The whole class travels through time, the school belle becomes Yu Ji and I become Xiang Yu

The uproar continued for several hours before it ended.

After the sky cleared and snowed in, Lin Yu walked out of the army tent to check,

I saw in the barracks, on the battlefield outside, and under the city of Chang'an,

Accumulated a thick layer of snow,

Enough to submerge soldiers' knees.

While Lin Yu was observing the situation, Zhou Yu walked back from the outside with great difficulty stepping on the snow,

Helplessly shook his head at Lin Yu and said:

"Brother Yu, the situation is not good, the snow is too deep."

"In this situation, even war horses can't run, let alone infantry,"

"In my opinion, I'm afraid we can't attack Chang'an until the spring of next year and the snow has completely melted."

"Besides Chang'an City, Cao Ren raised his exemption card,"

"Obviously they don't want to fight us."

Lin Yu frowned and said:

"That won't work."

"Cao Zhi hasn't responded to my messages for several days,"

"It is estimated that he is being tortured to death by Zhao Guo,"

"If it is delayed until next spring, he will definitely not be able to hold on."

"I can't just watch my old classmate get killed."

When Cao Zhi was mentioned, Zhou Yu also showed a sad face,

indeed,

It is urgent to save Cao Zhi.

"However, if it's freezing cold today and the snow doesn't melt, how can we break through Chang'an guarded by Cao Ren?"

Zhou Yu asked.

Lin Yu did not answer right away, but fell into deep thought looking at the white snow in front of him.

This heavy snow, looks like a hindrance,

But can it turn from a hindrance to an advantage?

The advantage of breaking through Chang'an City?

After pondering for a moment, Lin Yu suddenly had an idea, and said with a smile:

"I have an idea."

Zhou Yu asked curiously:

"What's the idea?"

Lin Yu smiled and said:

"Since it's snowing heavily, I will use this heavy snow to break through Cao Ren's guarded Chang'an!"

After saying this, he didn't explain any more, turned around and walked towards Huang Yueying's tent in the barracks.

Zhou Yu saw that he was talking halfway, and said depressedly:

"Brother Yu!"

"Brother Yu, don't go!"

"What the hell do you mean?"

"Explain clearly before leaving!"

Lin Yu disappeared on the snow without looking back.

Only an ethereal voice remains:

"You'll know when the time comes..."

"You will know..."

"understood……"

"That's right..."

"It's..."

Chapter 367 The Principle of Leverage

Stepping on the thick snow, there is a "creaking" sound under the feet,

Lin Yu soon came to Huang Yueying's military tent,

Opening the curtain and walking in, he smiled and said:

"Yueying, what are you busy with?"

However, when he looked up, he didn't see Huang Yueying's plump and graceful figure.

I saw a brazier next to the bed in the depths of the military tent, and under the quilt on the bed, there was a delicate figure trembling constantly.

_(:」∠)_

trembling...

Lin Yu suddenly realized when he saw it.

It was freezing cold, and snow had just fallen, and the temperature in the barracks dropped sharply.

The woman is already cold, and she does not have Lin Yu's innate and innocent holy body to resist the severe cold, so she will naturally shiver from the cold.

He hurriedly walked to the side of the bed, sat down beside the bed, and hugged Huang Yueying who was trembling constantly,

Thoughtfully said:

"Yueying, is it too cold?"

The poor beautiful woman said with trembling teeth: Wwω.Eьòókbá

"Yes yes yes... yes,"

"Ever since it snowed, this, this... this military tent has been... just as cold as an ice cellar..."

"It's so cold... so cold."

Lin Yu showed a sympathetic expression, and stretched his hand into the bed to test it out.

Can't help but shake his head and say:

"Oh, the rabbits are freezing all over."

"This is not good. If this continues, I'm afraid I'll catch a cold."

"That's all right, let me warm you up."

Lin Yu has an innate innocent holy body, he is not afraid of heat in summer and cold in winter,

Although the temperature in the military tent was extremely low at this time, his whole body was like a small stove, and he was not affected by the weather at all.

In the blink of an eye, he took off his armor three times, five times and two times,

He lifted the quilt and got into the bed.

this moment,

Huang Yueying just felt a warm current hit her, as if a large warm water bag suddenly appeared in her arms!

In this freezing environment, this kind of warmth is like the light in the dark!

She immediately wrapped Lin Yu tightly like an octopus,

happily said:

"Bawang is so warm!"

"Really amazing!"

Lin Yu smiled triumphantly, and said happily:

"of course,"

"I am the overlord of Western Chu, but I am the most warm-hearted man in the Qianyuan Continent!"

Then he bit Huang Yueying's fair and delicate ears, and said with a smile:

"Yueying, do you know how to get warmer?"

Huang Yueying looked bewildered, shook her head naively and ignorantly, and said:

"I don't know about myself."

Lin Yu smiled lightly, lowered his voice and said:

"Friction creates heat."

Huang Yueying's pretty face blushed immediately, and she twisted her body and started humming.

Lin Yu was unambiguous at all, and began to explain this simple junior high school physics knowledge to Huang Yueying.

……

Under Lin Yu's hard work,

Huang Yueying finally warmed up, no longer shivering,

After finishing his work, Lin Yu put his arms around her and said softly:

"Yueying,"

"Now the snow is so deep that Cao Ren can't hold on,"

"It is not so easy to break through Chang'an."

Huang Yueying deeply agreed, and while arranging her slightly fluffy and messy hair after the fierce battle, she said approvingly:

"Winter is not conducive to marching and fighting,"

"Heavy snow is not suitable for siege."

"There is snow and ice, and the city walls are icy and difficult to climb. If we forcefully attack the city, I am afraid that many soldiers will be lost."

Lin Yu said:

"But I have an idea, maybe I can turn the disadvantage into an advantage,"

"Break through the city gate in one fell swoop."

Huang Yueying was taken aback when she heard the words, a pair of star-like eyes shone with hope, and asked quickly:

"Overlord, please elaborate!"

Lin Yu took a pen and paper from the table next to the bed, and then the pen walked away, and began to draw a design drawing.

This design drawing was not original by him, nor was it a gift from the system, but it was written down in his mind.

The design drawing is very simple, and the core meaning is only four words——

The principle of leverage.

Here is a sketch of a catapult.

The catapult was originally designed by Liu Ye in the Three Kingdoms period, and it had not been adopted on a large scale in this era. Therefore, after seeing this sketch, Huang Yueying was shocked for a while!

"This is……"

"This is indeed a siege weapon!"

She sincerely admired it.

Lin Yu nodded with a smile, and said:

"Yes."
