With the placement of the key, the purple light of the entire stone ball was diffuse, and it continued to be intense, and in the end, the entire stone ball turned on its own like a Rubik's cube.

Wow!

Under the rotation of the stone ball, four pillars of purple light suddenly bloomed from the inside of the stone ball, and landed on the eyebrows of Chu Nan and the four of them, forming a ...... Purple Mark!

"This is our combined attack formation?"

Buju and the others were very surprised.

Carefully feeling the purple mark on the center of his eyebrows, he only felt that the mark contained extremely profound power, but he didn't know how to use it.

Chu Nan's heart moved.

Airplanes!

The purple mark on the center of the eyebrows suddenly opened, and the eyes were instantly covered with purple light.

And the purple seal in the center of the eyebrows of the three people seemed to activate with Chu Nan, and their eyes were instantly covered with purple light.

Under this purple light, they found that there was some kind of connection between them.

Not only can they transmit sound to each other, but they can also transmit power to each other!

They can even ...... with the consent of the other party Take control of each other's bodies!

In addition, every time the strength of the four of them improves in the future, the formation will inherit a part of the strength they have promoted, and this part of the strength will be equally divided among the other three.

In other words, if one of them has improved his strength, then the other three will also be improved!

"This ...... What kind of combined attack formation is this!"

Buju and Miao Shi were quite surprised.

This is completely different from the combined attack formation they have known before!

Even the most powerful combined attack formation they knew didn't have such a function.

Even Yang Wei, who has a certain degree of attainment in formation, said that he had never seen this kind of combined attack formation.

Chu Nan's mind was completely immersed in the purple mark on the center of his eyebrows at this time.

He could feel that the purple seal he had here seemed to be the eye of this formation, just like the control center of the entire formation.

In his feelings, in this purple seal, there seemed to be many rooms, each of which had an ability, but these rooms were locked and needed to be unlocked before he could obtain a new ability.

"I need your strength. ”

Chu Nan spoke.

When the three of them heard this, they did not hesitate to transfer their strength to Chu Nan through the formation.

This formation is very powerful, and the power they transmit to Chu Nan will not bring burden and discomfort to Chu Nan's body, even if the power they transmit exceeds the tolerance limit of Chu Nan's body, as long as it does not exceed too much, there will be no problem.

Chu Nan concentrated the power transmitted by the three of them on the purple seal in the center of his eyebrows, and coupled with his own strength, he suddenly formed a strong force to unlock the ability in the imprint.

The unlocking of these abilities requires great strength.

With Chu Nan's personal strength, it was completely insufficient.

Now, after combining the power of the three of them, he has finally barely unlocked one of the abilities.

This ability can be said to be just the basic ability of this combined attack formation.

After the imprint is opened, the four of them will have a comprehensive improvement in strength, protection, speed, and recovery.

And with such an improvement, their strength will be much higher than others in the same realm.

"It seems...... What other way can this uplift, even greater!"

Chu Nan could feel that there were many abilities in the entire purple seal, and they could even continuously enhance these abilities, but at present, they had just obtained this combined attack formation, and they still needed time and energy to study it.

Judging from Chu Nan's current feelings alone, if they want to unlock more abilities, they need the four of them to have more powerful strength to cultivate.

"I think in the Primordial Spirit Realm, it is already difficult for us to unlock other abilities, and we need to break through to the Spirit Fusion Realm before we can unlock them again. ”

Chu Nan told everyone.

The ability to unlock this combined attack formation requires a very strong force, and there are also requirements for cultivation, if there is not enough cultivation, it cannot be unlocked at all.

Everyone nodded.

The improvement that this combined attack formation has brought to them is huge enough, and the most important thing is that this combined attack formation has a strong growth potential, and with the improvement of their strength, the power and effect they can exert will become greater and greater.

In this way, after the combined attack formation was in hand, they did not stay here too long, and returned all the way back to the elite department.

Their harvest from this trip was huge, and now everyone was quite rich, and then they were ready to use this harvest in exchange for the cultivation resources they needed, and raise their cultivation to the Great Perfection of the First Spirit Realm as soon as possible.

They knew that a month before the start of the exorcism trial, the Elite Department would provide all elite students with a chance to break through the Primal Spirit Realm.

Prior to this, all elite students had to raise their cultivation to the Great Perfection of the First Spirit Realm.

After Chu Nan returned to the Elite Department, he began to think about another plan of his own.

He already had a specific idea in his head, and now he needed to make some detailed adjustments and refinements.

And the next plan, he is mainly aimed at Zhou Shao and the top of the elite department.

However, he also knew that with his current identity and strength, it was impossible to deal with the top level of the elite department like he did with Han Xiaolei's gang.

In fact, it is impossible to deal with the top of the elite department as an elite cadet.

However, he is very confident that as long as his plan is successfully implemented, it will inevitably cause huge losses to the top of the elite department, and he will slaughter them in the heart, so that they know what pain is!

"I'm Chu Nan, I'm not easy to bully!"

On the same day, Chu Nan began to prepare.

Meanwhile.

After Gong Zhifan and others returned from the Land of Secret Keys, they also attracted Zhou Shao's attention for the first time.

For their ambush this time, Zhou Shao was full of confidence and felt that he was nine out of ten.

After all, with the many treasures he provided, as well as Gong Zhifan's joining, he couldn't think of a reason to fail at all.

It's just that after Gong Zhifan and the others came out, before he could take the initiative to contact him, Gong Zhifan's roar had already been conveyed through the communicator.

"Zhou Yuanqi, I'm not done with you!!"

Zhou Shao was stunned, and before he could react, the communicator rang again one after another, and everyone's voices were heard.

"Zhou Shao, we can't afford to provoke this Chu Nan, we really can't afford to provoke it, you better find someone else......"

"All the treasures you gave us were snatched by him, so go find him and ask for them......"

"Zhou Shao, I advise you not to mess with this guy, this guy is ...... He's not human!"

Everyone's words made Zhou Yuanqi completely stunned.

This was completely different from the result he imagined, his brain was confused, and he didn't react for a long time.

It stands to reason that with their staffing and the treasures they provide here, it is impossible to fail, but now they seem to be not only failing, but ...... Fiasco!

"What the hell is this...... What the hell is going on!!"
