I started on a deserted island and encountered Ying Zheng, who insisted I was an immortal.

There, an endless sea of ​​golden flowers rippled in the sea breeze.

"Sir, what are those yellow flowers?"

Zhang Ying looked in the direction he pointed, her smile slowly fading, replaced by a hint of nostalgia.

"Oh, that's rapeseed flowers."

"Rapeseed flowers?"

"Hmm." Zhang Ying's voice was a little lower.

He gazed at the golden sea of ​​flowers, as if he had transcended time and space.

"When I was a child, the hillsides in my hometown would be covered with these flowers every spring."

"pity……"

"There's no going back."

"Sir, besides being ornamental, is this flower used for anything else?"

Ying Zheng's voice pulled Zhang Ying back from her brief daze.

"usefulness?"

Zhang Ying smiled; that sadness came and went quickly.

"It's incredibly useful."

He walked to the edge of the flower field and pointed to the rapeseed plants that had already formed green pods.

"When these pods mature and turn yellow, the seeds inside are black, and they are called rapeseed."

"Collect these seeds, roast them, and then press and extract them to make oil."

"Oil?"

Wang Ben was the first to lose his temper and cry out.

His concept of "oil" consisted only of the milky white lard rendered from fatty pork or the mutton fat rendered from sheep's tail.

How to extract oil from grass?

This is even more outrageous than the stories told by storytellers.

"Yes, oil, rapeseed oil."

Zhang Ying looked completely at ease.

"The hot and sour shredded potatoes you ate before were stir-fried with this oil, weren't they?"

One sentence left both Ying Zheng and Meng Yi speechless.

They recalled the taste of that dish: sour, spicy, refreshing, and with a pure, fresh plant aroma they had never tasted before.

It turns out that the fragrance comes from the oil extracted from these daylilies.

This realization overturned their common sense that they had held for decades.

The common people of the Qin Dynasty might not even get to eat a few drops of meat all year round.

Animal fat is a food that is just as valuable as meat.

But now, someone is telling them that oil can be obtained from plants that grow everywhere.

What does this mean?

Ying Zheng's heart skipped a beat.

This means that the Qin army will have a more stable source of oil, and the soldiers' physical strength will be greatly guaranteed.

This means that ordinary households can also use inexpensive cooking oil to improve their diet.

National strength and people's livelihood are all contained in this small patch of yellow flowers.

"Come on, let me show you the animals I keep."

Ignoring the three people's shock, Zhang Ying turned and walked towards the other end of the field.

He felt that explaining modern agricultural science to these drama queens was like casting pearls before swine.

After passing a trellis of melon and fruit vines, a huge enclosure with a fence made of thick wood came into view.

It covers an area as large as two football fields.

Inside, dozens of plump goats were leisurely grazing.

On the other side, twenty or thirty large wild boars were grunting and rolling around in the mud.

The tusks of these wild boars have clearly been broken off by humans, making them look less fierce and more cuddly.

Several brightly colored pheasants strolled around the corner of the fence, seemingly oblivious to their surroundings.

"Are all these your pets, sir?"

Meng Yi looked at the plump and strong wild boars, somewhat incredulous.

Wild boars are fierce and extremely difficult to tame; even the most experienced hunters dare not provoke them lightly.

"Yes, caught on the island."

Zhang Ying spoke of it casually.

"The males were all castrated to prevent them from fighting every day, so we kept two as breeding pigs."

He pointed in the direction of the pigsty.

"I'll just keep them. I'm too lazy to go fishing in the sea, so they eat these. They'll find their own food anyway, and I only need to feed them occasionally."

As he spoke, he walked to a thatched shed by the field and dragged out a huge wicker basket.

The basket was full of things.

It's a potato.

The basket was full, weighing at least 100 kilograms.

Ying Zheng and the other two stared at the basket of potatoes, still reeling from the shock of the vegetable oil.

Then they saw Zhang Ying drag the basket of potatoes to the edge of the pigpen, and with a forceful pull of her arms, dump the entire basket of potatoes into the stone pig trough with a "whoosh".

The twenty or thirty fat pigs seemed to have heard the signal to start the meal, and they swarmed over, burying their heads in the stone trough and making grunting chewing noises.

Crisp and melodious.

Wang Ben's body began to tremble slightly.

He looked at the potatoes that the pigs were rooting around in, each one so round and plump.

This very creature, capable of saving countless lives, is now being used to feed pigs.

Although he had heard Zhang Ying mention feeding pigs with potatoes before, seeing this scene still made Wang Ben feel a surge of bloodlust rush to his head.

"you!"

He lunged forward and grabbed Zhang Ying by the collar, his bruised panda eyes wide open.

"What a waste! You're really wasting precious resources!"

Zhang Ying was stunned by his sudden action and forcefully shook off Wang Ben's hand.

"Are you crazy? I feed my own pigs and use my own potatoes, what's it to you?"

"A divine thing? Divine my foot!" Zhang Ying thought this person was truly unreasonable. "I have so many potatoes here that I can't eat them all. If I don't feed them to the pigs, am I supposed to let them sprout and rot in the ground?"

Wang Ben pointed at the fat pigs that were happily eating, then pointed at himself, his whole body trembling.

"Sir, do you know that in our Great Qin, during years of famine, the land is scorched and barren, and people resort to cannibalism?"

"Sir, do you know how many ordinary people starve to death because they can't even afford to eat tree bark and grass roots?"

"This divine object, capable of sustaining countless lives, you use to feed these beasts!"

"You...is your heart made of stone?!"

As Wang Ben finished speaking, this man who shed blood but not tears on the battlefield actually had tears in his eyes.

Seeing his expression, Zhang Ying's anger subsided.

He sighed, thinking that this guy was really too immersed in the role, and had even become obsessed with it.

"Alright, alright, Lord Tongwu."

The Qin Dynasty has been gone for over two thousand years, can we please stop acting like this?

Zhang Ying's tone carried a hint of helpless mockery.

"You, a mere Marquis, have the right to control everything, yet you dare to tell me what to do, like feeding my pigs?"

These words were like a bucket of ice water poured over Wang Ben's head.

He stood there, stunned, and for a moment, he didn't know how to refute it.

Ying Zheng stepped forward, patted Wang Ben on the shoulder, and signaled him to calm down.

He knew why Wang Ben had lost his composure, but he was even more aware that provoking Zhang Ying at this moment would be a very unwise move.

"Old Wang was just concerned about the people; he acted rashly in a moment of panic. Please don't take offense, sir."

Ying Zheng spoke to Zhang Ying in a calm tone.

Just when the atmosphere was getting a little tense.

Zhang Ying's expression suddenly changed.

He stared intently at the bushes behind Ying Zheng.

"Old Ying!"

His voice suddenly became sharp and urgent.

"Don't move!"

As an emperor, Ying Zheng had never been reprimanded like this before.

He subconsciously took half a step back.

It is precisely this half-step.

A dark figure darted out of the bushes like lightning, so fast that no one had time to react.

"hiss!"

Ying Zheng felt a sharp, stabbing pain in his calf, as if he had been stabbed hard by a red-hot iron needle.

He looked down.

A venomous snake, entirely black with a triangular head, was biting his calf tightly.
