Crayon Shin-chan: As someone who's traveled through time, all I want is a huge reward!

Shinnosuke Nohara seemed quite confident in Lin Yu.

"I wonder what exactly Teacher Lin has prepared..."

Just when the whole family was curious and making guesses.

Lin Yu, Ijiri Yuhei, and the others had already opened the city gates and gone out.

Chapter 78 Surprise? No, it's a shock!

"Please find out from which direction the Ōzōi army will launch its attack, and the high ground in those directions."

Direction, commanding heights?

Although Ijiri Matahei Yoshitoshi was a little confused, as an experienced general, he immediately led Lin Yu to a suitable location according to Lin Yu's request.

"This is the main direction of the Ōzōi army's attack."

Lin Yu looked in the direction that Ijiri Yubei Yoshitoshi was pointing and observed for a while.

"As for the high ground, it's roughly over there, around here..."

Ijiri Yoshitoshi pointed out a few more vantage points, and Lin Yu nodded slightly.

"enough."

As he spoke, Lin Yu put down his bag, unzipped it, and under the astonished gazes of Ijiri Yuhei and the others, took out three riot shields.

"You can take these three shields for now, to guard against any sneak attacks from the shadows."

Ijiri Matahei Yoshitoshi had several of his men take the shield, which could almost cover his entire body, with strange expressions.

After taking out his shield, Lin Yu didn't stop there and continued to reach in.

In a short while, they took out a green cube that was about the size of a computer screen.

There were also some miscellaneous items, such as a support panel, and an instruction manual.

Ijiri Yoshitoshi curiously came over, only to find that they had no idea what the thing Lin Yu had just taken out was for.

Only one line of large characters could be seen.

This side faces the enemy!

That's right!

The surprise Lin Yu mentioned was the Claymore landmine he had extracted from the system!

Lin Yu still doesn't know what this thing is for, even after all this time.

After all, in modern society, there's simply no way it could be of any use.

We can't exactly send him to be a terrorist, carry out some kind of terrorist attack, and then go around gaining negative attention.

That would be far too inhumane and antisocial.

It doesn't align with his values.

But in the Warring States period, he had nothing to worry about.

This era doesn't care about morality or ethics, especially during this war; it's either you die or I live.

When Lin Yu read the original novel, he remembered that Da Zangjing told his subordinates that he should kill all the men and arrest all the women.

If the castle were to be breached by Ozurai, he would be in grave danger, and his friends, such as Ohara Nanako, would also be in peril.

Faced with this situation, it's impossible to talk about benevolence and morality, nor is it possible to be soft-hearted.

"Lin Jun, is this the surprise you were talking about?"

"Yes, that's right, this is it."

Lin Yu nodded without offering much explanation, picked up the Claymore mine, and began reading the instruction manual.

Although this is a military weapon, fortunately there is an instruction manual, so it is not that difficult to operate.

The instruction manual provided by the system is extremely detailed. Following the instructions step by step makes it almost foolproof.

Following the instructions, Lin Yu began the assembly process.

The others surrounded Lin Yu with riot shields, wary of any sneak attacks or the like.

In a short while, after adjusting the height and tilt angle, Lin Yu finally placed the first Claymore mine.

After orienting the direction towards the enemy's Ōzōi army, Lin Yu began laying electrical wires.

This thing needs to be detonated within 30 meters. If you get too close, it won't just damage the enemy facing that direction.

After setting up the first one, Lin Yu held the remote control in his hand and said to Ijiri Yuhei Yoshitoshi, "Later, have someone set up a simple cover about 30 meters away and stand behind it. When the enemy comes forward and hears my command, press this button."

Thirty meters?

Ijiri Matahei Yoshitoshi gazed at the enemy in the distance, his expression somewhat grave.

"Mr. Lin, if it's thirty meters... I'm afraid the people left here will..."

Thirty meters may not seem like a long distance, but in wartime, those who stayed there would have been cut off from all hope of survival.

Don't underestimate the mere thirty meters; once the battle begins, there's no chance of escape under a barrage of arrows.

Lin Yu naturally understood the meaning behind Ijiri Yuhei Yoshitoshi's words and shook his head.

"Just bring armor that can withstand arrows, and you don't need to worry about anything else."

Once the enemy gets close, the Claymore mines will detonate, and there will be no more enemies in front of us, let alone any pursuers.

Before Ijiri Yoshitoshi could say anything more, Lin Yu looked at him and said in a deep voice.

"Trust me, I won't have any problems."

"And Mr. Ijiri, do you know the old Chinese saying, 'A kind heart cannot command an army'?"

Upon hearing this, Ijiri Matahei Yoshitoshi remained silent for a moment.

Finally, he nodded and agreed to Lin Yu's proposal.

As a general leading troops, how could Ijiri Yoshitoshi not understand the logic in Lin Yu's words? He was only hesitant because of his own personality.

Next, surrounded by the crowd, Lin Yu set up a total of seven Claymore mines.

It can almost be said that the entire Ōzōi army was surrounded from all directions.

Both rain and dew are touched.

Lin Yu planned to place the remaining three on the city wall as defensive weapons.

Having taken care of all that, Lin Yu clapped his hands.

"Alright, send someone over."

"The wheat in the wheat field is almost ripe. If the enemy is going to attack, they should be able to do so soon."

Ijiri Yoshitoshi nodded and quickly began making arrangements, preparing according to Lin Yu's instructions.

Soon, several fully armed soldiers with resolute expressions and a death wish were selected to be responsible for detonating the Claymore mines.

"We will definitely complete the mission, even if it costs us our lives."

The group spoke with unwavering resolve, as if it were a mission they were certain to die for.

Lin Yu was too lazy to introduce anything to them.

Although firearms and gunpowder existed in this era, they were still far too rudimentary compared to modern weapons like the Claymore mine.

After taking care of all that, Lin Yu and Ijiri Yoshitoshi returned to the city.

In the city of Kasuga, everyone is now preparing for war.

Lin Yu watched as logs were rolled up the city wall, along with fist-sized stones, which were neatly piled up. He wasn't idle either.

The remaining three Claymore mines were also deployed, and we were just waiting for the enemy to attack.

Ohara Nanako and the Nohara family were overjoyed to see Lin Yu return safely.

But when they arrived at the city wall and wanted to greet Lin Yu, Hiroshi Nohara looked at the three green bumps standing on the wall and the words "This side faces the enemy" written on them, and his expression suddenly became somewhat astonished.

"Teacher Lin, is this the surprise you were talking about?!"

"Yeah, that's right."

"I've also arranged some things below, and I'm sure Daizo-ji will like them very much."

Chapter 79 The army presses the territory

Lin Yu spoke with a smile, but Hiroshi Nohara's expression clearly betrayed his inner turmoil.

"Wait, isn't this surprise a bit too much?!"

"This is a Claymore mine! It's definitely military equipment! Professor Lin, where did you get this kind of thing?"

As a middle-aged man, Hiroshi Nohara also had some interest in military matters.

Things that are relatively well-known can still be recognized.

Just like the most common RPGs in movies, it can be said to be very familiar to everyone.
