After the first two legions appeared, the last legion appeared.

Although they walked slowly, it was not because they were weak, but because they were too strong.

The last legion, all dressed in black heavy armor, marched in a phalanx of 1,000 men.

They carry machetes in their hands, and if they ride a horse, they will be death knights.

This unit is actually the high-ranking class of the undead, the Black Knights.

It is a unit that is a little weaker than the Death Knight.

But if you really want to say that they are weak, that's not necessarily.

They are considered to have been developed against the swordsmen on the human side, and on the human side, there is a level 8 class called the Dragon Power Swordsman, which is the existence that can directly kill angels.

So the Black Warrior level is not low.

On top of that, this entire legion is a Black Knight.

Starting with their commander-in-chief heroes, to ordinary heroes, to every soldier, all of them are Black Warriors.

Their weapons and equipment are all similar in style, and their means of attack are similar.

Even if the black warriors in the front battle formation die, the black warriors in the back can be quickly replenished.

It can be said that as long as the Black Samurai start a war, their battle formation will not be easy to break.

Even in the face of the Death Knight's charge, they can directly take it down.

And as long as the death knight has no impact, in the melee, he is really not the opponent of these black warriors.

So the combat effectiveness of this legion is actually very strong.

It's just that when they walk, they always wear armor on their bodies, and when they are not fighting, their movement speed is not very high.

And the commander of this legion not only did not care, but was very proud that he would have such a legion, and chose a nice name for his legion.

Legion of Stone.

A legion that doesn't sound like the direction of the undead at all.

When the three legions were advancing, Chen Gu had already seen the situation of the three legions from afar.

At this time, Chen Gu invited Zehir out for the first time.

"Hey, the location doesn't seem right, what's going on? Have you abandoned the spirits of the Holy City? ”

"The undead have sent three legions, and there should be other miscellaneous troops behind them.

Fighting the Holy City now is tantamount to putting our backs in front of the undead, Zehir, I plan to use the legion to attack, six hours, can you destroy these undead legions? ”

"Will anyone else come over but me?"

Zehir did not answer Chen Gu's question directly, but asked.

"The flying troops will be in position in half an hour, and the Hydra Legion will be on the battlefield in an hour."

"That's enough time, I need to look at the terrain and pick a suitable location for the big battle."

"I can help find what kind of location I need."

"No, the position of the battle is still up to me, there are some army positions, I need to think about it carefully, such as where to put the long-range troops, so that I can accurately hit the enemy and the battlefield.

In addition, the cavalry troops need a gentle slope that can be used to charge, the main force needs a melee battlefield, and finally we need to leave the troops for sneak attacks and counter-sneak attacks, these things are all things we need to consider. ”

Zehir explained the selection of the battlefield to Chen Gu as he took Chen Gu around the neighborhood.

Chen Gu understood that this was Zehir guiding him to study.

In this way, if he encounters some small battles in the future, Chen Gu can occupy the advantage of geographical advantages and not have to worry about things like too many losses.

These are Zehir's real means, and they are the foundation for him to become an elven marshal.

If it weren't for Chen Gu being the owner of the territory, he wouldn't have taught these things easily.

When Zehir was teaching Chen Gu how to set up the formation, the army of the undead had already appeared in the position they were ready to arrange.

Chen Gu held a battle formation map that had just been drawn in his hand, watched the army of the undead enter the battlefield, and couldn't help but ask.

"Zehir, can you get started?"

"It's not time yet, we'll make a move when they get to the middle of the battlefield, and only by controlling the time to shoot is in our hands, we can be regarded as occupying the time."

Chen Gu also smiled after hearing this, for an elf, who is also there to talk about the right time and place, this is somewhat funny.

But Zehir studied these things one by one through his own understanding of the battlefield.

Chen Gu also had to admit that Zehir's talent.

Looking at the speed at which the undead troops were advancing, Zehir explained to Chen Gu in a low voice.

"When deploying troops, in addition to the time being critical, you also have to adjust to the enemy's position.

Have you ever noticed that there is a small distance between the second legion and the first? ”

With the position pointed out by Zehir, Chen Gu really discovered that there were some wrongs.

"There is a contradiction between the three legions of them, no, no, no, it is the speed at which they move, and the Bone Legion at the front has actually been waiting for the troops behind.

The troops of the Second Legion were quite disorganized, and there were both fast and slow troops in their ranks.

So sometimes they want to speed up, but they can't improve.

The third regiment was the slowest to go, but I think they should have the quickest reaction if it comes to a fight. ”

"That's a good observation, so when do you think we should make a move?"

"When the third legion is about to get to our attack position, it should be when the distance between the first legion and the second legion is at its maximum.

At this time, the first legion will take the initiative to attack us, and will not wait for the second legion to catch up. ”

"Very good, although it is still a little close, but it is enough for the battle situation in front of me, I will retreat first, and you will arrange it later."

Chen Gu nodded, he knew that Zehir and the Phantom Legion were one.

Zehir could come out alone, but he couldn't have been here while the Legion was attacking.

If Chen Gu wants to use the legion to attack, he must let Zehir go back.

After Zehir left, Chen Gu took the crystal ball of the Phantom Legion and stared at the every move of the three legions in front of him seriously.

At this time, the three undead legions also discovered Chen Gu's existence, and their team suddenly underwent some small changes.

"Opportunity."

Chen Gu decisively judged that this was an opportunity.

He launched a legion attack directly.

All the troops of the Phantom Legion appeared directly on the nearby mountains and plains.

Because the location was already laid out from the beginning.

After the Phantom Legion troops appeared, they immediately killed the undead troops.
