Judging from the surface alone, the thickness of the black armor on Chu Nan's body surface has not increased much, but the color is much deeper.

And when the axe of the black humanoid puppet fell and slashed on the black armor, the black armor that was bound to have a large crack appeared earlier, but at this time, it only vibrated and there was no crack!

Even with Chu Nan's mouth, only a wisp of blood overflowed, and the damage was much smaller than before......

This made Chu Nan overjoyed.

The improvement of the seventh layer of black armor is very huge, in addition to the improvement of protection, there is also an improvement in cultivation, so that Chu Nan directly from the middle stage of the Primordial Spirit Realm to the late stage of the Primordial Spirit Realm.

With his current injury, even without the recovery of the elixir, he will be able to resist the axe of the black humanoid puppet within a certain period of time.

In this way, it is no longer difficult to pass this level.

"That...... Why don't you cut it slowly?"

Chu Nan looked at the red and ruthless eyes of the group of people in Buju, and couldn't help but speak.

After knowing that the Stacking Armor Gong had to be cultivated with the power of the anti-shock, Chu Nan felt that this was an excellent place to cultivate.

The black humanoid puppet is tireless and sane, and will constantly attack itself, bringing a steady stream of anti-shock power.

Such opportunities do not come around very often.

Buju and the others were desperately cutting down the tree, and after hearing the words, they were all stunned, and when they looked at Chu Nan, they also found that Chu Nan was not seriously injured in the axe chopping of the black humanoid puppet.

Chu Nan didn't hide it, and told everyone that he could practice armor stacking under the attack of the other party.

Everyone was amazed at this.

I've never heard of Stacking Armor Gong that can be cultivated under attack......

One by one, they were amazed.

At the same time, after seeing that Chu Nan could easily resist the axe slash of the black humanoid puppet, they were all relieved, knowing that it was no longer difficult to pass this level.

"I think...... We'll be the first team here to go through this level in this way......"

Miao She's expression was strange.

"It should be the last ......"

Yang Wei and Buju didn't know what to say.

This is obviously a level faster than the cutting speed, but because Chu Nan is directly in front of the black humanoid puppet here, and does not allow the black humanoid puppet to cut, this level has no difficulty.

Once this matter spreads, it will definitely cause a big shock.

A large part of the reason why Stacking Armor Gong is not valued in Shengcang Academy and no one cultivates it is because no one knows the correct cultivation method of Stacking Armor Gong.

I thought that I had to rely on a strong physique to cultivate more black armor.

Therefore, most of the students who practice the Stacking Armor Gong will find it difficult to make progress after cultivating the Stacking Armor Skill to the third or fourth layer.

Even if Chu Nan relied on spiritual food to enhance his physique, after cultivating to the sixth layer of armor, it became extremely difficult.

Fortunately, now he finally came to his senses.

This exercise......

It's purely an underwhelming exercise.

Under the uninterrupted attacks of the black humanoid puppet, Chu Nan felt that he had every hope that he could cultivate the eighth layer of black armor.

In this way, this was originally a level that was difficult for many people to pass, but now it has become Chu Nan's cultivation treasure, making his progress in the cultivation of Stacking Armor Gong indescribably fast.

This axe, which could have threatened his life, gradually made him feel a little comfortable when it landed on him......

"Am I addicted to beatings......

Chu Nan felt that this exercise had changed him a lot, turning him from a normal person to a beaten maniac who was addicted to being beaten and couldn't extricate himself......

Soon, when most of the trees in this area were cut down by a group of people, Chu Nan had successfully condensed the eighth layer of black armor!

At the same time, at the moment when this eighth layer of black armor was formed.

While!

The axe that fell on the black armor could not shake the black armor, and it could no longer hurt Chu Nan.

This made Chu Nan's heart full of joy.

Originally, starting from the sixth layer of black armor, the cultivation of each layer of black armor was extremely difficult, even if he knew that he had to cultivate with the power of the shock, he could not find a person who could constantly attack him......

It was only in this special environment that Chu Nan's cultivation speed reached such an exaggerated level.

This made Chu Nan a little reluctant to leave here......

"If only I could take this puppet away. ”

Chu Nan was thrilled by the black humanoid puppet in front of him.

However, when he cultivated to the eighth layer of black armor, the attack of this black humanoid puppet, in addition to being unable to shake his black armor anymore, could no longer bring him a boost in cultivation!

This made Chu Nan very depressed.

It was found that the anti-seismic force was too weak......

With the improvement of black armor and cultivation, the strength he can withstand here is also growing.

In this way, he would need even more powerful strength before he could use it for the cultivation of the ninth layer of black armor.

Now the attack of this black humanoid puppet is too weak for him......

This couldn't help but make Chu Nan feel pity in his heart.

If the attack of this black humanoid puppet could still allow him to cultivate, he could completely cultivate the ninth layer of armor here.

But Chu Nan is also a contented person.

This time, he has cultivated two layers of armor in a row, which is already a huge gain for him.

"In the later levels, there may be opportunities for this kind of cultivation!"

Chu Nan's heart was full of anticipation.

The crowd didn't know what to say, they were obviously here to break through, but now Chu Nan had turned this place into a place for cultivation, and they didn't even have the tense atmosphere they had earlier.

Later, they cut down all the trees in the area.

This is officially passed.

At one point, thirty purple keys appeared.

So that the number of keys they have here has suddenly reached sixty!

And just like the previous level, not only do two doors appear out of thin air, but there is also a quest reward that can be used for the next level, which is the black humanoid puppet!

It's a pity that this black humanoid puppet can only be used in these levels, and when they leave, neither the tomahawk in the first level nor this black humanoid puppet can be taken away.

And after going through these two levels, they are full of confidence in the next levels.

Especially Chu Nan's current eight-layer black armor makes him extremely resistant to beating, and once he encounters any powerful attacks in the later levels, he can directly go up to it.

In this way, the group of them quickly moved to the next level with a tomahawk and a black humanoid puppet.

Meanwhile.

On the fifth floor of the castle, after Han Xiaolei and the others arrived, they quickly laid an ambush here.

Now in this castle, except for Chu Nan and their team, there are no other teams, and they are not afraid of being injured by mistake, let alone Chu Nan and these people will not come to the fifth layer in exchange for the combined attack formation.

Even if Chu Nan and these people didn't get a single key, they would still come to the fifth layer.

Because the first floor is just the entrance, the fifth floor ...... is the exit from this castle.

Now, they are just waiting for Chu Nan and his gang to fall into the net.
