Just as Changsun Wuji was convinced, a burst of exclamation came from the river.

"It's cracked, it's cracked!"

"The ice cracks open!"

After Xue Yimang's eighth hammer fell.

There was a loud "touch".

The thick cracked ice layer could not bear the force and fell into the duck-green water, splashing water droplets more than meter high.

Li Shimin widened his eyes and stopped watching from afar, but walked forward with big strides.

Changsun Wuji was also shocked. His disbelief in his mouth actually felt that Li Yuanai could succeed. After all, he has created too many miracles in recent years.

The reason why I said it firmly was actually for Li Shimin.

Because Li Shimin didn't believe it, but he also felt that Li Yuanai could succeed.

So he said.

But even if he was mentally prepared, he could see the huge ice shattering and falling into the lake and his eyes were shocked and shocked.

Awesome.

Li Yuanai was very arrogant and hugged her chest with her hands, looking for granted, everything was under control.

This is the power of science.

As the saying goes, if you want to hit someone, learn to be beaten first.

The same is true in architecture. If you want to build a house, you must first learn how to demolish the house.

Hook's law discovered by British scientist Hooker is one of the foundations.

Simply put, the ice layer has a force point belonging to the ice layer. Li Yuanai planned out the ice layer that needs to be broken, calculated his force point, and destroyed the force point. The ice layer naturally could not withstand the attack of huge force and thus ruptured.

Just like demolishing a house, just find the key points of the building and bury explosives. Just a little explosive can overturn the entire building.

There is a similar plot in the classic American drama "Prison Break", which later generations. The protagonist used a trick-and-two device to open up a six-foot concrete wall. Although it is a bit exaggerated, it is also in line with scientific basis.

Seeing Li Shimin strode towards him, Li Yuanai hurriedly stood up straight and called the soldiers to cast a net to catch fish.

Li Shimin came close to look at the rectangular gap in front of him, his eyes full of shock.

It was not that he had thought of chiseling ice to catch fish. After all, in this harsh climate, if the soldiers could drink a sip of hot fish soup, it would also greatly improve the morale of the army.

It’s just that the ice layer is too thick, and soldiers swing their hammers and digging holes on it, which is neither dangerous nor efficient, so they can only give up.

Then now I just punched more than a dozen small holes and hammered the ice surface in just a few hammers.

"Sixteen, is it really yours? How did it do it?"

Li Yuanai explained respectfully: "My brother will build a house and will also demolish the house. The ice surface is like a foundation. My brother destroyed the foundation on the ice surface by drilling holes, and the ice layer will be vulnerable."

Such a simple explanation made the generals who accompanied him blushed.

They are also good at this, but they don’t understand!

I don't understand at all.

Li Shimin is the best. He never takes into account the cause and effect of things that he is not interested in. It doesn’t matter if he doesn’t understand it, as long as someone understands it.

"Don't go back, just stay here to help me. You immediately use the same method to dig a pit on this ice surface and arrange soldiers to fish."

Li Yuanai bowed and said, "My brother will accept the order."

At this moment, a burst of exclamations came from the surrounding area, "Fish, so many fish."

Li Yuanai hurriedly looked down at the river, and the fish under the water began to gather towards the gap, with as many as a hundred tricks.

Li Yuanai suddenly thought that when he was watching short videos in his later generations, he saw a polar bear fishing video and witnessed the special fishing skills of polar bears.

In winter, polar bears will crazily drill the ice surface, shoot a small hole, and then the fish will jump out and serve on the door, which is more dedicated than the takeaway in later generations.

I was extremely curious at the time and couldn't help but click on the comments, and immediately let the omnipotent netizens give them popular science.

That's because fish need to breathe. The river surface is frozen and is isolated from the outside air. The oxygen in the water is severely insufficient, and a gap is broken on the ice surface. When the air is transmitted into the water, the waters in this area are sufficient oxygen, and the fish will involuntarily gather at the gap.

Some anxious fish will even jump to the ashore to breathe.

Thinking of this, Li Yuanai hurriedly said, "Get out of the way! The fish are coming. Don't scare away the fish here. Just leave a few who can cast a net to catch fish."

Li Shimin didn't wait much after hearing this. The current importance of the entire army is the plump school of fish in the river.

Sure enough, with the gathering of fish, some fish really jumped ashore to die.

A skilled soldier could easily catch more than a hundred pieces of them in one net.

Li Yuanai began to use Hook's law to tear up the ice layer and arrange for soldiers to catch fish in this fish pit.

This is almost a hundred thousand troops, and it is not a small number.

Fortunately, the water is rich in resources at the bottom of the Yalu River, and the fish in the water are instinctively coming up to die because the river surface is frozen and lacks oxygen.

The legendary six-second memory was destined to send them to Tang Jun as food.

Yaluzha East Coast.

The Tang army, the Goguryeo army, separated by a river.

The movements of the Tang army could not be hidden from the Goguryeo Army. Looking from a distance, the Tang army caught the fat fish from the river one by one, and their eyes were straightened.

As Li Yuanai said, Goguryeo's food is indeed better than that of the Tang army.

The Tang army mainly used corn, but the side dishes were just pickled sauce.

The front line is too long and fresh food cannot be delivered at all. As for various meats, it is impossible.

Wouldn't it be better to have this energy to give some food?

Goguryeo is at home. As a fishing and hunting nation, there are many cured meat, jerky, salted fish and dried fish stocked in the country. They can not only eat corn and wheat, but also eat meat from time to time.

But seeing the Tang army carrying the fresh fish back to the barracks bag by bag, the soldiers' eyes turned red.

Yuan Gai Suwen looked at Tang Jun in the distance with a pale face, and his gums were itchy.

At this time, the camp gate opened wide, and 180 soldiers jumped out of the camp gate.

Yuan Gaisuwen was shocked and shouted, "Stop, who would allow you to go out?"

Soldiers under the camp stopped.

At this time, a voice came from behind Yuan Gaisuwen: "Let you go to dig ice and catch fish, you go, what are you going to do?"

The soldier heard this shout and stopped hesitating to go upwards.

Yuan Gaisuwen didn't say anything anymore, just to ask for trouble for Tang Jun opposite him.

Yuan Gaisuwen turned around and in front of him was an old man in his sixties, and smiled and said, "Why should Mr. Gao do this? If you want to eat fish, just say it to someone. Why take this risk?"

The old man's name is Gao Zhenhong, who is the leader of the Wu tribe, Nossa Guilou tribe.

The second most powerful among the five divisions is not the strongest, but he is the oldest and has the highest status. At this moment, the remaining four divisions obviously regard him as their respect.

Gao Zhenhong didn't say anything.

The other three Pinuosa also gradually came and said, "I'm afraid that you can't satisfy us if you take some fish. You're going to beg for food, so you might as well catch it yourself."

Just as he was talking, another soldier left the camp.

As the supreme commander of the military camp, Yuan Gaisuwen was completely unaware of it.
