After a fight, each with losses, Zhang Yu adjusted his defense.

The remaining well fences are protected and can no longer be destroyed by the enemy.

Although Lu Bu and the others destroyed more than half of the well fence, the situation did not improve much.

Because they lost a big general, it had a great impact on morale.

The next day, Zhang Yu sent troops again.

"It's not easy to fight, I guess I'll have to fight hard. I don't know how much will be lost. Looking at the tall city wall, Zhang Yu was deeply helpless.

I don't like this style of play, the loss is too big, but there is no good way to do it now.

The strong attack continued, and after a day of fighting, Zhang Yu's losses increased significantly.

Without more than half of the archers on the well fence to suppress, Zhang Yu's battle losses increased a lot.

At night, Zhang Yu walked alone outside the barracks, watching the soldiers patrolling back and forth, and also saw the soldiers on the well fence observing.

"That's right, the well fence can be seen from afar, and you can see everything on the top of the city, isn't this the watchtower of the future?"

There is a watchtower above, and the cannonballs below me are ready to be fired, as long as they are in command, the archers below will have eyes to point and shoot.

After having an idea, Zhang Yu hurriedly went back, and after going back, Zhang Yu found Guo Jia.

"Bong-hyo, let the soldiers on the well fence observe the movements in the city, and then command the archers below to let the archers strike accurately." Zhang Yu said.

Guo Jia thought carefully and said: "Lord, it is easy to command the direction, as long as the command flag is pointed, the soldiers can know which direction, but how to command the distance, this is difficult." ”

Guo Jia has a point, distance is the key.

Not only should the shooter know the distance, but the first observer must know how to visually measure the distance.

Visually determine the distance, and then add the direction, which can guide the archer to the target.

"There is a way, we will use the city wall as the baseline, and the archers below have been fighting for so many days, and they are very clear about the distance of the city wall, and they are very clear about the distance where they stand."

"After that, there is a view of the watchtower, and the archers can also hit targets behind the walls."

The purpose of the watchtower is not only to observe the movement on the city wall, but also to observe the movement behind the city wall.

Where there are more troops, where supplies are being transported, where are preparations for a storm, where are the positions of the archers.

All of this information is useful.

Zhang Yu trained a group of observers overnight, and then discussed with them how to command.

There are also some problems with the command, that is, the archer cannot always look at the commanding standard-bearer on the well railing.

Therefore, Zhang Yu set up a few people in front to observe the bannermen above, who faced the archers and turned their backs to the city wall.

However, this is dangerous, it is relatively close to the city wall, and it is already within the range of the enemy, so it requires several people with shields to protect them.

The standard-bearers on the watchtower pass the message to the flag-bearers on the ground, who in turn pass it on to the archers, all commanding the flags.

It is also simple to command, pointing in the direction with one hand and directing the distance with the other.

It is not difficult to command distance, and various actions represent different distances.

After Zhang Yu formulated a method, let them start practicing.

After dawn, Zhang Yu and the others began to attack.

Suddenly, there was an extra part of the well fence with a command flag in their hands, and there were two soldiers next to them to protect them.

The same is true of the city, where there are a few more people, most of whom are holding shields to protect a person.

As soon as the offensive began, a high-intensity war broke out between the two sides.

"It's strange, why are the archers of the Jiangdong army so disorganized today, is there some conspiracy?" Chen Gong guessed after reading it.

The flag-bearer on the well fence and the flag-bearer Chen Gong below both knew, but they hadn't guessed their role yet.

Chen Gong also guessed that it was the archers on the ground commanding, and the problem was that their combat effectiveness had dropped very badly by them as soon as they commanded them.

It's easy to understand that after the first flag-bearer commands, the flag-bearers on the ground can't immediately react accurately and give instructions to the archers.

And the archers can't react immediately after seeing these actions, and there are always many people who don't understand.

The archers are not timely when they shoot their arrows, and many people are still in the wrong direction and distance, which does not form a joint force.

The total reason is that this plan does not work smoothly.

"Send two more people up, one to direct the direction, one to command the distance, and the other to shout the distance to me." After watching for more than an hour, there were still too many mistakes when commanding, so Zhang Yu arranged for someone to go up again.

The flag-bearers selected by Zhang Yu are all from Jiangdong College, although most of them are elementary colleges, but their cultural level is not low, their minds are flexible, and they learn quickly.

After sending two more people out, the effect is obviously much better, at least as long as the flag bearer commands with one hand, the action will not go wrong, and there is no need to worry about the situation of drawing a square with one hand and a circle with the other.

At least some of the archers in front of you who could hear the shouting were quick and accurate.

The archer's skills improve, and his reaction speed gradually increases.

In the afternoon, Chen Gong found that the archers began to have a discipline, and sometimes they could cause a lot of damage to themselves.

The standard-bearers commanded more and more accurately, and they attacked wherever there were many people in the city.

"It's very troublesome that this Zhang Yu can come up with such a solution."

Now the power has not been fully reflected, but there are already signs, so Chen Gong has to be on guard.

Chen Gong tried several methods to kill those only standard-bearers, but in the end they were unsuccessful.

These people are well guarded, and unless you go out of town to kill them, it's hard to take them out with archers, or even javelins.

After trying it for a day, Zhang Yu felt that the effect was gradually reflected, and the archers had eyes, so the battle was much easier to fight.

The results of this day were not very good, because both sides were not yet familiar.

That night, Zhang Yu summoned all the flag bearers.

"I'll tell you, we should focus on attacking important targets, not just where there are many people."

"Key targets, unprotected targets, generals, transport teams, and timely suppression of the enemy and cooperation with the siege team."

Zhang Yu summoned them over for training so that they could command better.

The generals at the head of the city are undoubtedly important targets, staring at one person, hundreds of arrows are killed together, even if he can't be killed, he will be scared half to death, so that he can't concentrate on commanding, and one will hang up if he is not careful.

After Zhang Yu's training, these people returned to work.

This time, they will choose the target when they attack, and it is not where there are more people to attack.

For example, they found a young general at the head of the city and commanded hundreds of archers to attack together, and the young general was shot into a hedgehog.

As soon as the young general died, there was chaos around him.

This was a great blow to the enemy's morale, and many generals shrank back when they commanded, and the soldiers were afraid when they saw it.

In addition, there were people who carried rolling wood and stones, and they were in the closed beta, but after they were discovered, they were also attacked, and they were defenseless and were killed a lot.
