Metkai is a stubborn person, not as thoughtful as Kakashi. He heard Changfeng say he would wait for him for a while, and agreed without thinking.

"After you are ready, just tell me, I can start anytime."

He didn't ask Changfeng carefully why, and just put one hand behind his back and faced Changfeng sideways.

About two minutes later.

"The new day has arrived, your number of check-in times has been refreshed. At the same time, you have accumulated 7 days of sign-in, and the designated check-in location has been refreshed!"

"The current designated check-in location is [Koba Ninja Village - Naruto (290,990)]. Please arrive at Naruto before 23:59 today to sign-in!"

The system prompt sound in my mind made Changfeng slightly happy.

I didn’t expect that the designated check-in location would be Naruto. It was such a coincidence!

"You're waiting for me here."

Changfeng said to Maitkai, then turned around and walked towards the cliff.

"What are you going to do?"

"Take a deep breath."

When he arrived at the edge of the cliff, Changfeng issued a sign-in order to the system in his mind.

“Successfully checked in!”

"Congratulations on signing in at the designated location and obtaining [Strange Skills of Physical Art: Eight Gates Dunjia], the amount of chakra increased by 0.58%, and the money was 70,030 taels!"

"The reward has been issued to your system backpack, please go and check it out."

"Damn... the reward this time is actually the Eight Gate Dunjia?"

Changfeng couldn't help but feel overjoyed.

Sometimes things in this world are really such coincidences. Of course, he prefers that the system is giving himself "special care".

But it doesn't matter what it is.

He hurriedly opened the system backpack and checked.

At the same time, I felt a warm feeling in my body spread throughout every meridian.

The amount of chakra he currently has is no less than that of the Zhongnin, and even a special Shangnin.

Even though the total chakra volume only increased by 0.58%, Changfeng still directly felt his obvious growth in strength.

"Quantity change leads to qualitative change, and this sentence is never casually said!"

Changfeng laughed silently in his heart and looked at the skills in the system backpack.

【Secret of Physical Art: Eight Gates Dunjia】

The meridian system that can control the amount of chakra in a person's body and its flow and suppress or accelerate its release is called the "Eight Gates", namely the Open Door, Xiu Door, Sheng Door, Shui Door, Du Door, Jing Door, Jing Door, and Death Door.

Due to the excessively large chakra, the corresponding physical fitness is required to support it. Under normal circumstances, the "Eight Gates" will limit the amount of chakra in the human body to protect the human body.

Therefore, by unblocking the corresponding meridian acupoints where the eight gates are located, the body can temporarily gain powerful strength.

When the eight gates are fully opened, it is called the "Eight Gate Dunjia Formation". Those who open at this time can instantly gain more than ten times more than the Five Shadows.

It should be noted that the power of the Eight Gate Dunjia depends on the caster himself, and it increases exponentially based on the caster's own strength.

Therefore, after different people open the Eight Gate Dunjia, the increased power is different.

The most important thing is that after opening the eighth door, the "Death Gate" will eventually lead to death because of its own vitality entering an irreversible and rapid combustion.

Changfeng quickly swept the explanation and couldn't wait to extract this technique into his mind.

"Do you learn [The Secret of Physical Art: Eight Gates Dunjia] immediately?"

"study!"

The absolute risk of death after the eighth gate is opened is only for ordinary people. His immortal body, when he practices to the later stage, and has no seal regeneration, should be able to ignore the side effects of the eighth gate Dunjia.

So Changfeng chose to study without hesitation.

A large amount of information flow appears, turning into a permanent memory of Changfeng and stored in the mind.

In an instant, he completely mastered the method of opening the Eight Gate Dunjia.

But with his current physical strength, he had no idea which door he could open.

"call……"

Changfeng took a deep breath and turned to look at Maitkai.

"I have been practicing this technique secretly for many years. This is the first time I have been showing it in front of people."

"You're pretty good, Kay."

"Um?"

From the moment Changfeng turned around, Maitkai clearly felt an unprecedented invisible momentum released from the former.

He frowned, his expression became very serious, he immediately set off and prepared for the battle.

"Come on!"

Maitkai hooked his palm to Changfeng.

"Buzz--"

A slight wisp of chakra fluctuation was released from Changfeng's forehead.

In that moment, his clothes were windless.

The first door is to open the door, lift the brain domain restrictions, overload the energy of the body to increase strength and speed, and increase strength by up to 100%!

As soon as this door opened, the chakra aura on Changfeng's body immediately increased significantly!

Maitkai, who also practices the Eight Sects of Dunjia, is simply not too familiar with this scene.

As soon as he saw the change in the aura of Changfeng, he almost even widened his eyes!

"Eight Gates Dunjia? You..."

"The second door, close door, open!"

Changfeng sniffed again, opened the second door, lifted the fatigue limit, and increased the recovery speed of physical strength by accelerating the consumption of chakra and offset the excessive fatigue caused by physical strength.

"you……"

Maitkai's face became extremely solemn. He knew very well how powerful the Eight Gate Dunjia was.

Since the opponent used this move, he had to deal with it with the same trick, thinking that he quickly untie the bandages and weight-bearing turtle tools tied to his arm.

"The first door! Open!"

"The second door! Open!"

"The third door! Open!"

...

When the third door is opened, the color of the skin on the surface of Metkai's body has begun to change, because the accelerated flow of blood causes the skin to become congested and red.

At the same time, the skin, muscles, and even bones have begun to experience slight stinging pain, and the chakra in the body is burning faster, turning into blue-green steam and emitting on the surface.

He looked up at Changfeng opposite him and found that he was also staying in the third door.

"Although I don't know why you can also use the Eight Sects of Dunjia, since you are also practicing this physical technique, you should be very clear about its side effects."

Maitkai said in a deep voice.

"Ah, I know."

"The third disciple is the last safe area. Once you continue down, every move will cause physical damage and be full of fatal dangers."

"It can be said that starting from the fourth sect, it is considered the true 'Eight Gate Dunjia'."

After Changfeng finished speaking, the fourth door, the wounded door, immediately opened.

With a light "boom", the chakra on his body was released violently, and the green chakra steam on his body instantly surged by more than two meters, leaping straight up on the branches above his head.

At the same time, the muscles, bones, meridians, and every inch of the skin in the body began to feel very obvious pain.

Even with the repairing effect of the immortal body, this pain continues and cannot be completely ignored.

"Changfeng! You...!!"

"Prepare to take the call, Kai!!"
Chapter completed!
