The ten levels on the fourth level of the Key Land have always been difficult for people to break through, and even the teams composed of those upper elites have difficulty passing the levels here.

This is not to say that those upper elites are not as good as Chu Nan, but these ten levels are not based on the team's combat strength, on the contrary, there are not many levels here that test the team's combat strength.

These ten levels are more of a test of the whole team's adaptability, execution, tacit understanding, etc.

Of course, there is still a certain test for the overall strength of the team.

Like the snowball level, it requires someone in the team who is good at formation, and the whole team needs to have enough speed and strength to pass that level.

In terms of team combat power, Chu Nan may not be as good as those upper elites, but in these ten levels, they are ...... An unprecedented record!

When the four of them and four beasts passed through all the wanderings and appeared on the fourth floor of the castle, everyone changed dramatically!

Even the war beasts with them have changed a lot.

Among them, the biggest changes are Buju and Miao She.

In the later levels, they have different creations, which gives them a huge boost.

Although Yang Wei's improvement is not as great as theirs, he also has a lot of new understandings in terms of formations.

And Chu Nan is here......

Although the black armor on his body is still the eighth layer, it still hasn't reached the ninth layer, but it is not far from the ninth layer of black armor.

This time, his gain, in addition to the stacking of armor, also has an increase in energy value!

These increased energy values are derived from ...... Knock on Lima!

In one of the levels, the fire energy in the body of the knocker was greatly enhanced, so that it successfully gave birth to the spiritual fire!

And the spiritual fire it gives birth to is different from ordinary spiritual fire.

It is more powerful and changeable than ordinary spiritual fire.

This kind of spiritual fire can not only be used for combat, but also can solve the needs of Chu Nan when cooking spiritual food.

It can be seen from the fact that it brought Chu Nan a ten-point increase in energy value at one time, its improvement is extremely huge, and at the same time, this increase in ten energy points also made Chu Nan secretly draw a card.

Although I didn't draw the most wanted exercise enhancement card at the moment, I also drew a very useful attribute card.

[Attribute Card: Recovery +1]

[Uses: After use, it can be used to recover from injuries.] 】

This attribute card is undoubtedly extremely useful for Chu Nan.

The armor stacking skill he practiced was itself a technique to resist beating, and it needed to be practiced by constantly being beaten.

Even the attack he received is too weak to give him a boost, and it is better to have an attack that can make him injured, so as to bring a greater counterattack power.

In the next few levels, Chu Nan had suffered several terrifying attacks, and even his eight-layer black armor was almost blown up......

And the shock power brought about by this terrorist attack, although it did not allow him to cultivate the ninth layer armor, it also made him not far from the ninth layer armor.

Today's recovery attributes, when paired with his armor stacking skill, are undoubtedly a perfect match.

After all, he now needs to be beaten and injured in order to speed up his cultivation......

The recovery effect brought by the spiritual food is not good, and after having this recovery attribute card, Chu Nan no longer has to worry about injury in the cultivation of the Stacking Armor Gong.

"Now, I'm really beating up the maniac......"

For such a thing as being beaten......

Chu Nan didn't resist either, especially after the cultivation of the Stacking Armor Gong reached this stage, many times those attacks fell on him, but it would make him feel very comfortable......

After these ten levels, in addition to their personal improvement, in the team, their tacit understanding and understanding of each other also enable them to better cooperate and play a stronger strength.

What they lacked now was a powerful combined attack formation!

As long as they have a combined attack formation, the combat power of their team will not be weaker than any team in the elite department.

In addition, after breaking through the ten levels, they have reached 300 keys in terms of keys!

This number of keys is quite terrifying, and it can be exchanged for the combined attack formation here at will.

"Unexpected...... We have completely passed these ten levels!"

Yang Wei sighed for a while.

Buju and Miao Shi also had a feeling as if they were dreaming.

When Chu Nan originally decided to come to this fourth layer, their hearts were full of apprehension, and they all felt that Chu Nan's heart was too big, but they didn't expect the final result to be ten levels, all of which were cleared, and they obtained three hundred keys at one time!

They knew that the reason why there was such a result was that Chu Nan played too much of a role here......

If there was no Chu Nan, they would definitely not be able to pass any of these ten levels.

In fact, the breakthrough of these ten levels was not in Chu Nan's original plan.

When Chu Nan told them about the plan, he didn't say that he was going to come to the fourth layer, this was a temporary decision made by Chu Nan.

Now is the time for them to execute their plan.

"The big fish above should be impatient to wait. ”

Buju licked his lips, his eyes glinting with anticipation.

Yang Wei and Miao Shi also laughed.

If they had just arrived, they would still not dare to be careless about Han Xiaolei and her gang.

After all, in terms of combat power, although they are not afraid of Han Xiaolei's gang, they lag behind them in terms of numbers.

Moreover, when Chu Nan told them the plan at that time, he had already speculated that it was impossible for Zhou Shao to sit idly by, and he would inevitably put some treasures on Han Xiaolei's gang to enhance their combat power to ensure that nothing went wrong.

It's just that Han Xiaolei's gang has the improvement of treasures, and Chu Nan and the others have gained even more improvement in the ten levels!

"Let's go, after preparing for so long, it's time to close the net. ”

Chu Nan grinned, led everyone, and began to head to the fifth floor of the castle!

Although there are no more level rooms on the entire fifth floor, it is extremely large, much larger than the four floors below.

When Chu Nan and the others came to the fifth layer, they were in the middle of the fifth layer, and in front of them, there were two paths to choose from.

One leads to the left and one to the right.

"Where should we go?"

Miao Shi looked at Chu Nan.

Don't wait for Chu Nan to speak here.

Call!

Suddenly, black mist came from all directions, and in an instant, these black mist enveloped Chu Nan and the others, blocking their vision, so that they could only see things within one meter.

The black mist quickly wrapped around their bodies like chains, as if binding their bodies, making them unable to move.

At the same time, along with these black fogs, there was a gloomy laughter.

"You ...... You don't have to go anywhere. ”
