The Qin army retreated all the way, and the Zhao army followed them all the way.

While retreating, the Qin army fired fire bombs and ignited the plants and trees to protect the flanks with a fire wall.

The Zhao army's cavalry could neither bypass the mountains nor rush forward, so they could only follow behind slowly.

In fact, the Zhao army's cavalry could bypass the mountains on both sides, but the time spent may be much more than waiting for the Qin army to retreat on the spot.

So the two armies slowly "maintain contact".

Occasionally, a few cavalrymen shot a few arrows at the Qin army, but they were quickly shot back by the Qin army's crossbowmen.

Infantry can use the crossbow.

The cavalry either uses a bow or an arm to open a crossbow, and of course the front cannot be defended from the much longer range of the crossbow.

After finally retreating to the Great Wall, the Qin army hurriedly deployed defenses under the city, but suddenly found that the cavalry in the north were gone.

Fatty Tun asked with lingering fear and expectation:

"May the Zhao army retreated, right?"

Chen Bing smiled:

"How can the Zhao army retreat?"

"Li Mu will not give up until he comes here!"

"Wait!"

Cang was shocked in an instant:

"Then why aren't there?"

"What should I do?"

"Senior brother, think of a solution..."

Shen Bing was speechless.

He is a man or not a god, and he cannot solve any problem.

The knowledge and skills he brought from modern times may be okay to deal with ordinary people.

For example, Xuchang and Wang Bai.

But he was unable to deal with Li Mu.

Because he is a war god with rich experience in combating cold weapons.

An invincible military strategist.

A central figure who is respected and respected by the military and civilians of Zhao State.

...

He can almost be said to be the peak of this era and the soul of Zhao State.

If Shen Bing is given some time and resources to develop, he may be able to fight against it.

But Shen Bing only came to this world for a few days, and he has been poor and busy with survival.

Then he bumped into this evil star head-on. How can I find a way?

After waiting for a while, the more everyone could not see the enemy, the more they felt panicked. Everyone looked nervous like a tense arrow string.

Chen Bing sighed in his heart:

Li Mu is indeed a military force, knowing how to play with the enemy in his palms, especially his mentality.

Then, even Yang Ting couldn't stand this kind of depression.

She walked out of the city tower, with Zhang Xuan, whose injuries had not yet been healed...

Since Tian was "harmed by heroism", the only 2500 masters who are older than Zhang Xuan, so he became Yang Ting's assistant again.

This is a good thing, because Zhang Xuan and Chen Bing were already together at this time.

If Li Mu's army was at the city, it would not be a good thing if the Qin army was still in conflict.

Yang Ting stood on the city tower and looked into the distance, and walked back and forth several times anxiously.

When he saw Shen Bing standing under the city, he shouted: "Shen Bing, go to the Arrow Tower!"

Chen Bing responded to the promise and turned around and climbed up the steps.

But this time, I was not as confident as usual.

As soon as Chen Bing walked into the arrow tower, Yang Ting, who was restless, immediately asked in a row of cannons:

"Then why didn't the Zhao army attack?"

"Do you have a strategy to defend against the enemy?"

"How can I rescue the general?"

...

Another person who regards Shen Soldiers as gods.

Chen Bing's helpless answer:

"The lieutenant forgives his crimes, and his subordinates have no plans to defend against the enemy."

"There is no way to save the general."

"I'm afraid this time..."

Yang Ting interrupted Chen Bing without thinking:

"Don't bully me, how could you not have a way to defend against the enemy?"

Shen Bing was speechless for a moment:

Who was going to Matou Mountain just now?

Who is going to burn Li Mu?

Blame me?

But of course, Chen Bing would not answer like this.

"I don't know if the lieutenant still remembers that the attack was greater than the defense?"

Yang Ting replied:

"certainly!"

"Our army has to disperse its forces to guard the Great Wall."

"However, first you have your 'responsible soldiers and show that the enemy is weak', and then Tian was 'explored to help the enemy'."

"What can Zhao Jun do to me?"

Chen Bing sighed:

"One time and another time."

"At that time, I was facing Xuchang, but now I was facing Li Mu."

"Showing the enemy is weak, the doubtful soldiers may be able to deceive Xuchang, but how can they deceive Li Mu?"

Yang Ting asked again:

"So what about exploring the enemy and supporting him?"

The so-called "exploration of the enemy and support" is what Tian said before, and then reinforce wherever the enemy attacks.

However……

Chen Bing shook his head and said negation:

"This method may be possible for infantry."

"The infantry marching slowly for only fifty miles a day."

"We can check the enemy's whereabouts in time before changing the deployment to rush to reinforcements."

"Now what Li Mu is leading cavalry..."

There is no need to say more about the next one.

The advantage of cavalry is its high mobility, and it can be said that it can be at least a hundred miles a day.

So even if you know which direction the cavalry is heading, the Qin army is afraid that it will not be able to rush forward to reinforcements.

If Li Mu used the cavalry to play the trick of beating east and west, the Qin army would probably be transferred like a monkey.

Therefore, Chen Bing had to bow helplessly:

"Forgive the incompetence of my subordinates."

"Unless the general leads the main force and breaks out and arrives at the Great Wall in time."

"Our army may have the power to fight!"
