The so-called innate and acquired nature is the division of the realm in this world. The acquired nature is equivalent to the Qi storage period in Yan New World. Acquired nature perfection means the Qi storage completion.

The innate period is the stage of meridian opening, and the innate one is called the master in this world. The owner of this body, Xu Zhengyan, is in this state and has opened the first meridian, the hand sun meridian.

Yan Xin is still in the Qi storage period, and he knows very little about the Opening period. He only knows that the internal exercises of the Opening period can open the twelve positive meridians of the human body and form a large internal circulation, also known as the small world of the human body, and then open the Ren and Du meridians, known as the bridge of heaven and earth, so as to communicate with the big world of the outside world with the omnipotence of the void, and feed back the small world of the human body, thereby achieving the realm of anti-emptiness. Every move and gesture can transform the energy of the void for one's own use, and every move brings the power of the heaven and earth.

Through Xu Zhengyan's memory, Yan Xin discovered that the innate exercises in this world, that is, the innate exercises, are not complete. For example, the Xiyang exercise practiced by Xu Zhengyan is still the same as in the Qi storage period, but when it comes to the Qi opening period, there is only the method of practicing the left hand sun meridian.

After opening the hand sun vein, the power of the Xiyang fist used is greatly increased. It can emit fist energy through the left hand and cause damage from the body. The fist energy has a brilliant power, just like the rising sun and the sun is coming, and the evil demons retreat. But that's all. If the twelve regular meridians cannot be opened, it will not be able to form a small world in physical strength, and the true qi cannot naturally circulate in the body.

Not to mention opening the Ren and Du meridians, connecting the heaven and earth, feeding back the void of all things to their own small heaven and earth, and further achieving anti-emptiness.

Xu Zhengyan remembers that the cultivation of other people is roughly the same. For example, the heroic technique practiced by his brother-in-law Zhen Yingxiong, the Qi-storing period is the same as in the present world. After the innate nature, he only cultivates the Yangming meridian.

However, the internal and mental methods of this world cannot be practiced at the same time, that is, the practice of opening different meridians cannot be practiced at the same time to achieve the possibility of opening two or even more meridians.

There are thirteen acupoints in the hand solar vein that Xu Zhengyan practices. As long as the three acupoints at Quyuan, Shaoze and Xiaohai in the middle are condensed, the hand solar vein can be initially opened and reach the innate realm.

In addition to these three acupoints, Xu Zhengyan also condensed the other seven acupoints in turn. Only when the remaining wrist bones, Houxi and Qiangu were all condensed, they could become the master of this world.

This is the general situation of Yan Xin's current body. He is now in the Demon Cloud Castle. If he wants to rescue his niece Zhen Cailing, he may have to face two masters, "Vajra Butcher" Murong Bei, who are in the same realm as him, "Beautiful Snake Demon" Wan Yanyao, and Meng Feiyun, the master of the Demon Cloud Castle who has completely opened all the acupoints of the meridians he has cultivated.

The situation is not optimistic! Yan Xin thought.

The main line given by the Immortal Furnace is to survive for one hour, that is, two hours. Yan Xin decided to hide in this room first, give it to the main line, and then see what the main line is. If there is no conflict, he will do his best to rescue Zhen Cailing.

As for why he had to save Zhen Cailing, it was because Yan Xin considered a problem that he was just a temporary passerby in this world, and his body was temporarily borrowed and used. When he left, he would have to return it to the main owner.

Le Yuan, who was in the previous world, had long been completely lost after suffering a blow, like a living dead person. In addition, he was old and weak, and was about to die. Yan Xin naturally had no taboos when using it, and did whatever he wanted, without any burden in his heart. The final outcome of death might be exactly what the Lord hoped, let alone died for the sake of chivalrous and righteousness.

But this world is different. The main master’s biggest obsession at the moment is to rescue his niece Zhen Cailing. If he only cares about completing his main line, regardless of Zhen Cailing, it will lead to an accident during this period. What should the main master do after she leaves? What do you think?

As a person with a bottom line and principled self-righteousness, Yan Xin feels that what he needs to do is to do while completing the main line while doing his best.

The Five Sects of Zhengdao have previously questioned through spies and disciples of the Demon Cloud Castle, and have drawn up the map of the Demon Cloud Castle, and have also figured out the approximate work and schedule and operating mode. Xu Zhengyan made sufficient preparations before setting off and remembered them all in his heart.

There are three floors above the Moyun Castle. The first floor is the hall, the second floor is the living place for high-rise buildings, and the third floor is Meng Feiyun alone. There are two floors underground. The first floor is the living place for ordinary disciples and servants of Moyun Castle. The second floor is the dungeon, which is Xu Zhengyan's destination.

There are two patrol teams patrolling every day in the fort, from the second floor to the second floor of the underground, and conducting repeated inspections, with a quarter of an hour apart.

Yan Xin is now located on the basement of the Mo Yun Castle. After Xu Zhengyan sneaked in, in order to avoid the patrol team that happened to patrol the basement, he casually found a room to hide, and then Yan Xin came over.

The patrol team only inspects public areas such as corridors and does not patrol every room. In addition, Yan Xin, who has the highest cultivation level in the patrol team, is not as successful as a acquired state, and is already innate. After restraining his breath, he is not worried about being discovered at all.

Therefore, Yan Xin simply sat cross-legged in this room, familiarizing himself with the running route of Xu Zhengyan's martial arts, while waiting for the main task to be completed.

Every quarter of an hour passed, a patrol team passed by outside. Yan Xin silently remembered the seventh time in his heart, and estimated that it would be less than a few minutes away from an hour.

When Yan Xin thought that he would soon complete the main task 1 and the Immortal Furnace could remain on, he couldn't help but feel a little ups and downs.

At this time, the sound of the patrol footsteps came into Yan Xin's ears again.

Yan Xin quickly calmed down, kept the ancient well without waves, and calmed down his breath.

Don't go to the last step, but be careless and fail.

The footsteps were getting closer and closer, and they had already reached the door where Yan Xin was, and then continued to go in.

Just when Yan Xin thought it was the same as the previous seven times, the patrol team suddenly stopped, and there was a silence outside the door.

Something happened!

Although I don’t know why there has been a change, it will definitely not be a good thing. Yan Xin was instantly alert, and the true energy in his body flowed like water, ready to turn into the most powerful energy at any time.

One second,

Two seconds,

Three seconds,

Quiet outside,

Silent inside.

Four seconds,

Five seconds,

six…

A sound of poncho!

The wooden door was split into pieces, and countless wood chips turned into hidden weapons from the outside to the inside, shooting towards every corner of the room with a whizzing sound of breaking through the air.

A figure followed the flying wood chips and entered the room, and the weapon in his hand turned into a shadow and slashed towards Yan Xin.

Yan Xin was already wary of it. At the moment when the wooden door was split, he suddenly stood up, and his feet were not bad, and he punched out with his left hand. The extremely fast-moving true energy in his body was like a dam breaking a dam, rushing out along the sun's veins in his hand.

The energy that broke through the body emitted a strong golden light, like the sun in the sky, with a brilliant momentum, smashed the wood chips shot towards Yan Xin, hit the weapon that turned into a afterimage, and repelled the figure that broke into the door.
Chapter completed!
