Zhang Fei's replaceable fourth skill is called ten thousand men are invincible.

When Chen Ze heard the introduction of this skill, he was severely surprised.

Without him, this skill is really abnormal.

If Zhang Fei doesn't bring a soldier, his force value will increase by as much as 100 points to 247 points!

This force value is the highest value Chen Ze has seen so far. He even believes that even Lu Bu, who is known as the invincible in the world, does not necessarily have 247 points without the technical support of generals.

When attacking Xifeng City, didn't Xu Qing, who entered the city, show his magic power because of Zhang Fei's martial arts skills, so as to frighten the defenders in the city at one fell swoop?

If it weren't for Zhang Fei's skill, he would be able to beat Xifeng City, but it would be much more difficult.

However, because of this, this skill looks very powerful, but it is a icing on the cake skill.

Does Chen Ze need icing on the cake now?

No, he needs help in the snow.

No matter how strong Zhang Fei is, he can't fight the enemy's 400000 people alone. No matter how high his force value is, he can't help being surrounded by a sea of people.

Therefore, even if Chen Ze appreciates this skill again, at this time when the enemy is approaching, he can only change an individual general skill for Zhang Fei first.

The reason why we chose Zhang Fei instead of Zhao Yun is that Chen Ze configured Zhao Yun with a group growth skill. Group growth or Ma Teng's skill of reducing the benefits of the other group is the most suitable general skill in the situation of playing more with less.

What kind of skills can be given to Zhang Fei is a problem.

That's why Chen Ze took Li Quan'an and Meng Yang out of the city to look for possible opportunities when there was a systematic map.

After turning around and coming back, Chen Ze had a dispute in his heart. Only then did he divide 10000 people from the army and go out of the city led by Xu Qing.

While walking, he was crazy about buying generals. In order to find suitable generals as soon as possible, he even spent a lot of money and chose epic generals.

So after consuming a lot of war achievements, Chen Ze got what he wanted.

Jiang Wan, the Prime Minister of Shu Han, is a famous official known as the four prime ministers of Shu Han together with Zhuge Kongming.

People who can be called phase with Zhuge Kongming are naturally very strong, but Chen Ze forced himself not to see Jiang Wan's numerical value, but only focused on his second military general skills.

Ambush!

You can lead soldiers with the maximum command power to ambush in advance. Within a mile of the ambush, the combat power of all ambushes will be doubled!

This is the same skill as Cheng Yu, which can double the combat effectiveness of soldiers ambushed in advance!

When defending the city in Xiyun City, Chen Ze used this ambush plan to double the fighting capacity of the soldiers defending the city, and then caused a heavy blow to the poison fog army with a catapult at an unexpected distance.

This time, Chen Ze still wants to repeat his old skills, so the first thing to do is to prepare the catapult first.

In order to make the projectile hit by the catapult exceed the enemy's expectation, you have to cooperate with a person who has the plan of ambush, that is Cheng Yu.

Then Cheng Yu can only stay in the city to provide group gain for the soldiers and command some archers to attack with arrows and rain.

But Chen Ze doesn't want to stick to it. He understands that with the thickness of urban defense of Xifeng City, there must be no possibility that he can't stick to it.

Not to mention anything else, because of Yan Haomiao's relationship, the enemy knows that he has only 100000 people.

Only 100000 people, how to defend the attack of 400000 troops?

The other party only needs to divide troops to besiege the other three city gates, and Chen Ze's forces can't be pulled open. He can't evenly distribute 100000 people to the four city gates. In this way, there are only more than 30000 people in each city gate. What a fart?

Therefore, he needs an ambush to attract fire outside the city, and even accidentally cause a heavy blow to the enemy.

Zhang Fei is the most suitable candidate for this task.

Although his generals' skills sound very suitable for attacking the city, in fact, whichever of his first three skills is taken out is also suitable for the frontal killing of the two armies.

With an ambush plan that can double the combat capacity of his soldiers, it is not easy for the enemy to take advantage of Zhang Fei.

Moreover, Zhang Fei's greater advantage over Cheng Yu is that he has two types of soldiers.

As long as the soldiers' command type is set to cavalry and archers, it is possible to attack and escape. You can pull the enemy's front by flying a kite, so as to greatly alleviate the pressure of guarding Xifeng City.

Therefore, the ambush plan is very important for Chen Ze's city defense plan, which is why he wants to get this skill at the expense of a lot of war achievements.

As for buying other legendary generals directly.

On the one hand, the time is tight. On the other hand, he is not sure what kind of skills the newly purchased legendary generals will bring him, and whether they are suitable for guarding the city.

What's more, it's still the same old problem. He doesn't have enough troops on hand!

The so-called clever woman can't make bricks without rice. There are generals but no soldiers. What's the use of a legendary general?

If the generals alone can win the victory, he doesn't have to replace Zhang Fei's invincible skills. Let him really take charge of the pass. Isn't it over?

Therefore, in the end, Chen Ze chose to replace Jiang Wan's ambush plan with Zhang Fei. Even if so, he would lose one of the four phases of Shu Han forever, Chen Ze could only express helplessness.

Time is very tight. He doesn't have time to make too many choices in the selection of generals. He is lucky to get the ambush skill. He can't be picky.

After replacing the generals' skills, the people also came to the predetermined incubation point with Chen Ze, which is not the only way for the troops of the three border cities, but slightly close to the interior of Fengqi province.

The commander of the other side never thought that Chen Ze not only dared to divide his troops when his own forces were far inferior to the other side, but even placed the divided forces in the interior of Fengqi province.

Such a bold act, isn't he afraid that if reinforcements arrive from Fengqi Province, they will make dumplings for him and even destroy the whole army?

Chen Ze is really not afraid.

He knew very well in his heart that even if reinforcements arrived at Fengqi Province, it would never be Xifeng City, but the three border cities with empty rear defense!

Even Chen Ze can imagine that at this time, there must be troops rushing to the three border cities to fill the defensive space of the three cities after the 400000 troops leave.

After all, Yan Haomiao still leads millions of troops around the periphery. If there is no support, the three border cities dare to make such a big fuss, that's a ghost.
