"What? Why didn't the father hear about it?"

Li Er frowned. It seemed that the thing Xiao Zhengtai said could break the city should be it.

"Your Highness, what you are talking about are those strange-shaped tubes?"

Cheng Yaojin's eyes were very confused. Before leaving Chang'an, he deliberately learned what the use of His Highness was. He remembered that the only thing His Highness responded to him was a mysterious smile.

"tube?"

Li Er was even more confused. What was he doing when he went to war to bring these things? If Xiao Zhengtai had no idea in his mind, he wouldn't believe it if he was beaten to death.

"Father, don't underestimate these inconspicuous tubes. Whether they can break the city, we all have to rely on him. This is something that my son spent a lot of time to make."

Xiao Zhengtai smiled mysteriously and just briefly explained it, but there was no explanation for what their actual function was.

"Zhinu, can you tell your father first what these tubes do?"

Since he had already started asking, he didn't mind asking the bottom line. It was so uncomfortable to have a slight understanding of it.

"Free fire prevention. If we had known we would have gathered together, if the enemy used fire attack, we would have been very passive."

Xiao Zhengtai said seriously, this is that the Goguryeo soldiers had problems in their heads. If they used burning arrow rain to attack them, their losses would definitely be even more serious.

Hearing Xiao Zhengtai's unreliable explanation, Li Er's eyes almost flew out. It was snowy and worried that the enemy would attack with fire. Isn't this nonsense?

"Father, look at this."

Seeing Li Er's unscrupulous gaze, Xiao Zhengtai directly poured the tea in front of him onto the ground.

The hot tea stayed on the ground for only a few minutes and then completely frozen into ice.

Li Er was very confused and looked at Xiao Zhengta for some unknown reason. It is normal to have such an effect in such a cold weather. Can he use him to demonstrate this to himself?

"These pipes brought by Father and son are not ordinary pipes. They are water guns that can be fired through mechanical principles, and the spray distance is very considerable.

As long as we pour boiling water into the water gun when the weather is cold, and then shoot them into Gaimu City, what effect will you think will be."

After saying that, Xiao Zhengtai looked at everyone with a smile on his face. He didn't believe it. He had explained to this level, and everyone would not understand.

"It's amazing! In such a ghost weather, it will be impossible to shoot water directly into Gaimu City. It will be an ice city there. Even if the Goguryeo soldiers have a lot of supplies, they will not be able to experience such things.

You can destroy this unbreakable city without spending a soldier. Your Highness’s wisdom is indeed not something they can imagine.”

No one present was a fool. After Xiao Zhengta explained, everyone's eyes lit up. They didn't expect such a wonderful idea.

"Haha, it turns out that God is helping the Tang Dynasty. Pheasant Nu, it is a blessing for the Tang Dynasty to have you here!"

After so many days, Li Er finally showed a laugh. After so many days of persistence, there was finally a result. It can also prove that there is indeed no word failure in his dictionary.

"Your Highness, I'm afraid that the entire Goguryeo soldiers would never dream of being frozen to death one day. Your Highness's wisdom is indeed admirable."

Cheng Yaojin hurriedly gave him a tough flattery. He was anxious these days. Now that he finally got a result, how could he not be excited?

"Uncle Cheng praised it. My nephew just played with a water gun in summer. With the current environment, I was just inspired by the feeling."

Faced with everyone's praise, Xiao Zheng waved his hand quickly. Although he thought of the solution, he would definitely not be able to accomplish it alone.

"The solution is good, but you should not think too easily. You should know that the range of the water gun is limited. If you cannot shoot water into Gaimu City, everything is empty talk.

You must be clear that once we enter their attack range, the enemy's rain of arrows will shoot at us without any mercy."

Li Er spoke at this time to interrupt everyone's laughter. There was no definite way, so it was still very difficult to perform the task.

"Father, you don't have to worry about this. I have calculated that the effective range of ordinary bows and arrows is only about one hundred meters, and the strong bows are only about one hundred and fifty meters. The water gun I designed quietly has an effective range of more than three hundred meters. The problem you are worried about just now does not exist at all."

Seeing everyone thinking, Xiao Zhengta grinned. Such difficulties were nothing to do with him.

Of course, such a thing is simple, but if you really want to operate it, it would be impossible to complete without the cooperation of ten or eight soldiers at the same time.

After hearing Xiao Zhengtai's words, Li Er glanced at him deeply. If he said that he was not prepared, he would not believe it if he was beaten to death.

I'm afraid that before he went to war, this little boy had already started planning. Once he encountered difficulties, he would support him as soon as possible.

Li Er was not ashamed of his life as a small strategy as his son, not to mention that he lost many soldiers because of his wrong decision.

"Since there is a way to break the city, Cheng Yaojin obeyed the order and immediately ordered the soldiers to put all the big pots on and start boiling water to rain on Gaimu City."

Li Er had been impatient for breaking the city. Now that he had such a clever plan, he naturally would not miss it, nor would he want to delay it.

"My minister, follow the order!"

After Cheng Yaojin respectfully received the order, he almost left. He also wanted to see what kind of virtue the frozen monkey would be.

With such an order, the entire Tang Dynasty soldiers began to get busy, constantly going out to cut trees, chop firewood, and burning water, causing a lot of noise.

Gaimu City also set up its own post, so the actions of the Tang soldiers were naturally impossible to hide from their eyes. They passed the news back immediately.

"Get off, something you don't have the eyesight to see. As long as it's not a big deal, don't bother me."

Xue Gang, the lord of Gaimu City, grabbed the dried fruit in front of him and smashed it over. He looked angry. The soldiers of the Tang Dynasty had been stalemate with them for so long. What's the point of making fire and cooking now?

What's more, if you didn't see him having sex with the beauty, this thing that doesn't understand the charm, you know that destroying his elegant delight and not punishing him on the spot is already his kindness.

The soldiers who came to report were beaten out by the city lord. Thinking about it carefully, the city lord seemed to have nothing wrong with cutting trees and burning fire, because they were cold or improving their food.

"General, why do you get angry about this? How could those little ones be the general's opponent? If they really had a way, how could they be delayed until now?"

Seeing the city lord angry, the woman hurriedly arched into his arms, and her body kept twisting in his arms, constantly teasing his emotions.

"Haha, you fairy, today I will let you see the power of this city lord and let you see what a real warrior is."

After Xue Gang finished speaking, he directly removed the animal skin from his body, revealing his black chest hair, gently lifted the woman's chin, and his eyes were filled with lewd light.
