Traveling through the Great Northern Wilderness and marrying the most beautiful educated youth.

The spray dosage calibration sheet from the Dongfeng Brigade.

I just locked it in the metal cabinet.

Han Changsheng then took the homework diagram.

They came back.

"Accountant Wei."

"I'll ask you too."

"Which flight is the third one?"

Wei Dacheng opened the homework sheet.

"576 mu".

Han Changsheng placed the drawing on the table.

"I'll go ask about the numbers too."

"No need to ask about the acreage."

Wei Dacheng stopped.

Tian Xiaoman leaned closer to take a look.

The map only shows a red pencil line.

Which trip started from which place?

Where to fly and stop.

Not a single penny.

Logically speaking...

"The area matches."

"What do you care about the number of trips?"

Han Changsheng raised his eyelids.

"Stop spraying halfway through the flight."

"Land and then get up again."

"Which route should I pick them up from?"

Tian Xiaoman pointed her hand at the picture.

"Check if the bean leaves are wet."

Xu Chunyan shook her head.

"The wind blows."

"It wasn't done before."

"Let's get to the bottom of this first."

"What are you looking at?"

Old Gu used that oval spray nozzle.

Put it on the corner of the table.

"Repeat it once."

"Eat the bean leaves again."

"One less."

"Leave a long strip of insect."

"The total acreage is all written correctly."

The room fell silent.

Su Qingyun opened the drawer.

Take out a blank sheet of paper.

Wei Dacheng handed over the pen.

Su Qingyun continued writing.

Route connection record sheet.

Task partitioning.

Starting marker.

Termination marker.

Effective spray width.

course.

Flights.

Airplane number.

Number of spraying passes.

The number of trips was empty.

Stop spraying position.

Restore position.

Signal numbers at both ends.

Ground counter.

Substitute counter.

Pilot's log.

Landing point verification.

Local person in charge.

Tian Xiaoman looked down and counted them once.

"Eighteen items."

Su Qingyun flattened the paper.

"The plane will fly over there."

"It doesn't mean the medicine will be sprayed over there."

"Which time did you turn on the shower?"

"You must remember this clearly."

……

It was a little after 8 a.m.

A Jeep.

Two medicine trucks followed behind.

It stopped at the entrance of the work station.

The car door opened.

A square-faced man came down.

A map clip was tucked under his arm.

He was also carrying two wooden plaques in his hand.

He glanced at the watch on the table as soon as he entered.

I scanned a new order.

Only then did he extend his hand.

"That Comrade Su Qingyun, right?"

"I'm going to the Red Flag Commune too."

"Advanced Brigade".

"Secretary Liu Zhankui."

Su Qingyun shook hands with him.

"Secretary Liu."

Which plot of land?

Liu Zhankui spread out the diagram.

"Xigang soybeans".

"Three thousand mu."

"Meadow borer."

"Ten networks and forty-five articles."

Insect infestation.

There are seventeen items in total.

Liu Zhankui placed the two wooden plaques.

Put it on the table.

"Airline routes are also regulated."

"One per head."

"The plane will take you there."

"Move the wooden sign twenty steps to the side."

"I even went and practiced with the people there."

Han Changsheng picked up the wooden sign.

One piece reads "South".

One piece reads "North".

"Who moved it?"

"Two militiamen."

"A southern head."

"One north end."

"Taking the same steps?"

Liu Zhankui was taken aback.

"It's all twenty steps."

Old Gu raised his eyelids.

"A very tall guy."

"A little dwarf."

"Can you walk to a place in twenty steps?"

Liu Zhankui's lips twitched.

Logically speaking...

"Just one or two steps away."

"The plane can be aligned in the air."

Han Changsheng picked up his flight cap.

"Go to the field."

"Let's see your twenty steps first."

"How far exactly?"

……

Xigang Bean Field.

Both the north and south ends.

Each of them had a militiaman standing there.

The one in the south has broad shoulders and long legs.

The one in the north is only sixteen or seventeen years old.

It was just taller than the wooden sign.

Liu Zhankui got off the car.

He waved to the two of them.

"Just like yesterday."

"Go through it once."

The militiamen from Nantou strode forward.

It takes twenty steps.

They stuck the wooden sign into the ground.

The young man from the north also took twenty steps.

He stood still, holding the wooden sign.

Wei Dacheng took a steel ruler and measured it.

Nantou.

Twenty-three and a half meters tall.

North end.

Sixteen meters and nine inches.

Two wooden plaques.

It slanted out almost seven meters.

The smile on Liu Zhankui's face.

It disappeared in an instant.

"Why is there such a big difference?"

The young man's face turned red.

"I'm going too, even though I have short legs."

"We can't just give up now, can we?"

The militiamen from Nantou quickly shrank back.

"Then should I take fewer steps too?"

Old Gu spat.

"Pooh."

"A young man."

"More than a mile."

"Fly to the middle of the earth."

"Won't the flight paths become a twisted mess?"

The production team leader stood to the side.

I'm a little unconvinced.

Logically speaking...

"The bean field is so big."

"You can't tell if it's a few meters apart."

Han Changsheng did not argue with him.

He pointed to the track.

"Fill it with clean water."

"Lay out the paper."

……

No one is allowed to enter the fields.

Tian Xiaoman led the militia.

On the outer sides at both the north and south ends.

Each of them pulled out a steel ruler.

First, take a picture of twenty meters away.

Two sets of wooden stakes were driven in.

On the farm road in the middle of the field.

Three more black tarpaulins were laid horizontally.

On each strip of tarpaulin.

A row of absorbent paper was pressed down.

Unit 1 only holds 300 kilograms of clean water.

The first trip.

Follow the wooden sign at the south end.

According to the wooden sign at the north end.

The second trip.

Walk twenty steps in each direction.

Let's fly again.

After the plane landed.

Xu Chunyan took the absorbent paper back.

Article 1.

The two water droplets pressed together.

It weighed more than four meters more.

Article .

It's just right in the middle.

Article 3.

Between the two water droplets.

Leave a white border blank.

The widest part.

Nearly three meters.

The production team leader stared at the white border.

The mouth stopped moving.

Han Changsheng picked up the paper.

It was handed to him.

"Nantou is spraying again."

"The north end is leaking water."

You said you couldn't tell.

"You can tell it's an insect."

Liu Zhankui handed over three sheets of paper.

I looked at them one by one.

His face darkened slightly.

"Old Lu."

"How did you practice yesterday?"

The production team leader rubbed his hands together.

"I'll go and think about it too."

"Twenty steps is twenty meters."

"Who can walk one meter in one step?"

Old Gu raised his eyelids.

"You even know that?"

"Knowing that, why are you using your leg as a ruler?"

Several militiamen were standing nearby.

I couldn't help but chuckle.

The production team leader lowered his head.

I didn't dare to talk back.

……

The steel ruler was pulled back.

The bean field is located at both the north and south ends.

Every twenty meters.

Drive a short stake into each.

The pile heads are painted white.

Then write the number in red paint.

Number One.

Number Two.

Number three.

They lined up to number seventy-five.

Both the north and south ends.

Wooden stakes of the same number must be aligned.

Which one is off-center?

Measure again.

Liu Zhankui looked at the row of wooden stakes.

He frowned again.

"Let the plane take a trip."

"Move the signal to the next number."

"This time it finally worked, right?"

Han Changsheng looked at the two counting boards.

"What if we don't turn on the shower?"

Liu Zhankui was stunned.

"The plane has already landed."

"Can't we just not open it?"

Tian Xiaoman raised her hand and pointed at the wind bag.

"The wind shifts."

"Stop."

"The signal is not right."

"I also need to make time."

"On the ground, you can only see the planes pass by."

How do you know if it's been sprayed or not?

Han Changsheng handed over the flight itinerary.

"The aircraft numbers are separated."

"Unit 1, western half."

"The eastern half of Unit 2."

"Every time I go."

"The counters at both ends should check the spray first."

"I see the showerhead is on."

"Only then can you turn the number."

"Passed by empty-handed".

"Only remembering the empty moments."

"Immovable sign."

Liu Zhankui took the order.

"Do pilots keep records too?"

"After landing."

"I'll go report one last time too."

"Two numbers on the ground."

"A number in the sky."

"Nine don't match."

"Don't keep flying."

The production team leader muttered under his breath.

"Three people together."

"I'm also afraid that the more I count, the more confusing it will become."

Su Qingyun glanced at him.

"One person miscounted."

"Who knows where we went wrong?"

The production team leader opened his mouth.

It closed again.

Liu Zhankui pulled out the wooden plaque.

I personally inserted it next to the number one stake.

"middle."

"This time we won't measure by the legs."

"Don't even use your brain to guess."

……

11:20 a.m.

Northwest wind, level 2.

The wind direction is consistent at all three locations.

Record it three times in a row.

It's not chaotic.

The actual track length is 694 meters.

The ground is hard.

Both ends are empty.

The work area has been cleared.

Security was in place at all four locations.

The nozzle's flow rate is set at half a minute.

All correct.

Four thousand five hundred kilograms of liquid medicine.

The sampling at the top, middle, and bottom is consistent.

Gao Jianjun turned the abacus twice.

"Unit 1".

"The first flight weighed 900 kilograms."

"Unit 2."

"Nine hundred kilograms."

"None of them exceeded the limit."

Han Changsheng sat in Unit 1.

First, look at the white cloth indicating arrival.

Let's look at marker number one again.

Finally, he looked at Tian Xiaoman.

"route?"

Tian Xiaoman held up the record sheet.

"The north and south stakes have the same number!"

"Start-up One!"

"The spray width is twenty meters!"

"One counter each for the north and south!"

"No account will be updated if the page is left blank!"

Han Changsheng nodded.

"Remember the takeoff."

Two An-2 helicopters.

They rushed off the track one after the other.

Liu Zhankui stood at the south end.

I didn't check the medicine mist first.

First, keep an eye on the counter.

The first spraying operation of Unit 1.

Turn to number two at the south end.

The north end also turned to number two.

The second trip.

Both ends flipped to number three at the same time.

The first flight landed.

Counting from the south.

Fifteen trips.

Counting from the north.

Fifteen trips.

Han Changsheng took off his flight cap.

"Fifteen trips."

Three numbers.

Not one was missing.

Wei Dacheng is on the map.

Numbers one through fifteen.

Mark each lane in red.

Liu Zhankui reached out and touched the wooden stake.

"Fly according to number."

"It's much clearer than looking at a bean field."

……

The third sortie had only flown halfway through its flight.

The white cloth at the northwest end.

Suddenly it swayed due east.

The meteorologist picked up the piece of iron.

when.

when.

when.

The signalman crossed two red flags.

The white cloth covering the aircraft was quickly folded up.

Aircraft number one in the air.

We just entered the line from the 37-yard mark.

The showerhead isn't turned on yet.

I saw the stop spray signal.

Pull it up immediately.

Go around the work area.

The counter at the south end saw the plane pass by.

He casually played the cards.

I turned to number thirty-eight.

The young man from the north didn't move.

They're still holding onto 37 yards.

The production team leader saw it.

Quickly shout towards the north.

"Flip the card!"

"The plane has passed!"

The young man hugged the wooden sign tightly.

"I didn't see any medicinal mist."

"Cannot be turned over."

The production team leader's face darkened.

"I saw it from this side too."

Don't make a big deal out of nothing.

"Quickly flip through it."

The young man's face turned pale.

But his hand didn't move.

"That's what Captain Han said."

"No criticism."

"Even if the plane passes by, it doesn't count."

Liu Zhankui walked over from the edge of the field.

First look at the thirty-eighths in the south.

Then look at the thirty-seventh point to the north.

His expression slowly darkened.

"Who made the mistake?"

The counter at the south end rubbed his hands together.

"I'm going to watch the plane land too."

"It flipped over."

The production team leader quickly responded.

"Just one more step."

"Wait for the wind to return."

"Just keep flying at thirty-eight."

Logically speaking...

"A difference of twenty meters is nothing."

Tian Xiaoman took the previous piece of white paper.

It was snapped into his hands.

"That's a small amount."

"Take it back."

"Should we get the bug to sign something?"

The production team leader's face froze.

He didn't say a word.

After Han Changsheng landed.

Open your notebook.

"Finished after thirty-six sprays."

"Thirty-seven yards."

"Passed by empty-handed".

Wei Dacheng looked at the counting boards at both ends.

"North end is right."

"Nantou Cuo".

Liu Zhankui ripped off the wooden sign at the south end.

Insert it back into the 37 yards.

He turned and glared at the production team leader.

"Missing one isn't a big deal?"

"Twenty meters wide."

"More than two miles long."

"Several dozen acres of land."

"What will you use to make up for it?"

The production team leader wiped his forehead.

"I'll go think about it too..."

Don't even think about it.

Liu Zhankui took the white-edged paper.

She tucked it into his arms.

"We won't be able to see the medicinal mist anymore."

"Don't touch the cards with your hands."

……

The wind calmed down for twenty minutes.

Three white cloths.

Turn southeast again.

The meteorologist took three measurements.

Northwest wind, level 2.

Han Changsheng finished reading the record.

They asked again from both the north and south ends.

"Thirty-seven yards?"

Nantou held up a sign.

"Thirty-seven!"

The person in the north followed suit and raised a sign.

"Thirty-seven!"

"Was the blank space recorded?"

Wei Dacheng looked down at the order form.

"Unit 1".

"A wasted trip."

"The work area wasn't calculated."

Han Changsheng then put on his flight cap.

"recover."

The first aircraft took off again.

This time, they entered the line from 37 yards.

The medicinal mist was completely spread out.

The nozzles at both ends are visible.

At the same time, turn the card to number 38.

Liu Zhankui slowly exhaled.

"I almost called it by chance."

"Several dozen acres were lost."

The next two sorties.

After each flight.

Nantou reporting number.

Beitou Fuhao.

The plane landed.

The pilot reported it again.

On one occasion, livestock ran outside the cordon.

The signalman signaled the stop of flying flags in advance.

The plane circled around the ground.

Neither side turned the card over.

This time, the production team leader stood to the side.

Put your hands behind your back.

I didn't even dare to touch it.

……

Before it gets dark.

The last aircraft landed.

Both the north and south ends.

It stopped at number 75.

Old Gu checked the spray nozzles first.

There was no traffic jam.

The traffic volume remained unchanged.

Gao Jianjun lay on the cover of the oil tanker.

The abacus was turned twice.

"Five sorties."

"Nine hundred and sixty liters of oil were used."

Tian Xiaoman was holding the medicine tent.

They then immediately began counting off.

"Installation solution".

"Four thousand five hundred kilograms."

"Five kilograms of liquid remain."

"Recycle according to regulations."

Wei Dacheng spread out the map.

Xigang soybeans.

Seventy-five air routes.

Mark each line with a red pencil.

"Practical exercises".

"Three thousand mu."

"Two empty trips."

"Stop spraying once."

"The restored positions are all correct."

"No re-brought."

"Nothing was missing."

Xu Chunyan placed the paper in the middle of the ground.

They were laid out one by one.

Between each two lines.

The application of the medicine is evenly distributed.

There are no white seams.

There are no heavy wet areas.

Liu Zhankui took the work order.

Then I put the route connection record sheet.

Flip through it from beginning to end.

When I saw the 37-yard correction record.

My fingers paused for a moment.

"President Su."

"I'm going today too."

"It's called 'twenty steps'."

"Measure out a huge hole."

"We walked the same amount of time."

"It doesn't mean the plane will fly with the same precision."

Su Qingyun pushed the inkpad over.

"How will I receive calls if the connection is lost?"

Liu Zhankui pressed his fingerprint again.

"Steel ruler for stake setting".

"North and South have the same name."

"Only after the criticism is launched will the card be turned over."

"Record the blanks separately."

"Three numbers, one in heaven and one on earth."

"It doesn't match up."

"No one is allowed to continue this line."

The young man from the north stood at the back.

She pursed her lips and remained silent.

Liu Zhankui pointed at him.

"This short guy today."

"More than you high-ranking officials."

"They stand firmly."

The production team leader blushed.

Fold that piece of white paper neatly.

Stuff it into your shirt pocket.

"I'll go to the back too."

"Hands aren't as fast as eyes anymore."

Old Gu raised his eyelids.

"Don't let your brain outpace your counting."

Laughter erupted from the crowd.

……

The next afternoon.

Xu Chunyan returned from the Advanced Brigade.

She handed over the follow-up examination report.

It was placed on the table.

"Xigang soybeans".

"More than 80% of the live insects have been suppressed."

"Seventy-five air routes."

"We checked each one individually."

No missing tape was found.

"There was no heavy use of medicine to burn the leaves."

Wei Dacheng opened the new folder.

Insect infestation.

Route connection record sheet.

There are eighteen items in total.

He raised his head.

"President Su."

"This picture."

"How do I write the number?"

Su Qingyun picked up the pen.

Write it on the cover.

The Northern Wilderness Voyage, Part 16.

He took out the route connection record sheet.

Place it at the back of the dosage calibration sheet.

Then they took the test spray paper with the white edge showing in the middle.

I folded it and tucked it inside.

Wei Dacheng counted them once.

"Eighteen items now."

Su Qingyun closed the folder.

"One picture."

"Eighteen items."

"One thing is missing."

"It's not finished yet."

Han Changsheng stood at the door.

I glanced at the counting boards lined up against the wall.

"How many times has the plane flown over?"

"This only proves that it was here."

Su Qingyun locked the metal cabinet.

"The total number of trips to the bean field is not recognized."

"Yes, I admit it."

"Every application of the medicine is required."

"Did it fall behind or not?"
