The original version of "Golden Bell Cover" started with pure body refining. After the internal force was born, both body refining and Qi training were synchronized. However, the more important the Qi training went to the later stage, the more it became more prominent, and it was pure Qi training until the end. This is the biggest feature of "Golden Bell Cover".

However, Chen Kan's modified "Golden Bell Cover" is different. It will not be pure body refining or qi training. Only when he first started practicing, it is pure body refining. Although the internal energy has not yet been generated at this time, the internal energy transformed from the qi can also be improved through body refining, so it can be considered as qi training.

Especially after the first level is completed, internal energy will arise, that is, the real body refining and qi training will be carried out simultaneously, until the Golden Bell Cover is finally practiced, which makes it more difficult to break through the improved version of "The Golden Bell Cover".

As mentioned before, you must break through the internal energy and physical body at the same time before you can enter the next level. Now that the physical body Chen Kan has reached the level of success in the first level, it is not as good as the internal energy.

Internal force absorbs the vital energy that originally exists between heaven and earth, and then stores it in the body for one's own use. Chen Kan cannot learn the internal energy and mental methods of this plane because his meridians are different from those in this plane.

Under Lu Zhu's guidance, Chen Kan practiced this "Golden Bell Cover" that could produce its own internal strength, except for the legendary characters.

As long as the first level is complete and internal energy is born, Chen Kan can start to operate his internal energy in his body. Thinking about the internal energy he has always dreamed of will appear, Chen Kan is a little excited.

Chen Kan sat down in a Zen room with his five hearts facing the sky, and then began to temper his internal energy according to the method recorded in the secret book.

"Crash..." First of all, there was a sound of running water, which was the sound of blood flowing rapidly in the blood vessels, and it was also mixed with a slight "Crash" sound of heart beating.

Then a thin layer of qi film appeared on Chen Kan's body surface, which was almost integrated with the skin. This is the embodiment of the great achievement of the external qi realm of internal martial arts. Because the internal qi and internal qi stay on the surface, it is called external qi.

As the sound of running water slows down, the air membrane outside the body is slowly fading and then disappearing, and the body is like cooking shrimps and it begins to slowly turn red.

After Chen Kan entered the Gangjin, he could see inside, so Chen Kan knew very well what was going on in his body. It was originally just an internal energy that existed on the surface and began to enter the inside, the inside of the muscles, the inside of the internal organs, the inside of the meridians, and the inside of the bones...

If Chen Kan expected it was right, this should be the process of internal martial arts from external qi to internal qi, but now it is transformed from qi to more advanced internal qi.

The secret book said that this process will be very painful and lasts for a long time. Now Chen Kan has started sweating.

The internal energy that entered the muscles began to slowly enter the bones, and then there was the bone marrow. Chen Kan had never felt this severe pain before. Compared with the pain this time, the pain of each breakthrough before was so insignificant. Chen Kan even wanted to faint directly so as not to suffer such pain again.

This is just the beginning. The process of internal energy entering the bones is long, and the process of entering the internal organs is even longer. Every part of the body is in pain, and every place is in pain.

Entering the heart, Chen Kan felt that his heart stopped beating, and entering his lungs, Chen Kan felt that he could no longer breathe...

There were waves of colic from the internal organs, and the continuous pain was like someone was holding a mixer to stir their internal organs one by one.

"Ah..." Chen Kan finally couldn't help it and screamed. Now the internal energy began to enter the meridians, acupoints, and the acupoints in the body felt like they were hit hard, and no matter which acupoint was not spared.

Now, even if Chen Kan wants to faint, it has become a luxury, because the severe pain is so painful that it is impossible to even faint.

With a "drink." Chen Kan jumped up, "Bang!" He stuck his feet on the ground, stood up and down, hoping to relieve the pain in his body.

Although Chen Kan gritted his teeth tightly, the painful moans still came out through the gaps of his teeth, and his voice was low and hoarse, making people creepy.

Seeing Master Chi being outside the door, he also heard the sound, but he did not enter the room. The rosary in his hand was turning faster and faster, and his lips moved faster and faster, which showed that his heart was not calm.

Being able to hear the sound means that Chen Kan is still persisting, and the situation is pretty good; if you can't hear the sound, either Chen Kan will hold on or...

Both Chen Kan and Master Jianchi knew that this level was the most difficult to break through, but they didn't expect it to be so difficult.

At this time, Chen Kan began to expel some black dirty things on his body, which were the debris squeezed out by the internal energy entering his body.

If Chen Kan saw this scene, he would be very surprised. Chen Kan always thought that after he had been strengthened by serum and heart-shaped grass, all the impurities in his body should have been cleaned up long ago.

These are just some impurities on the body, and some impurities have been cleaned up by the internal organs, but those impurities cannot be directly excreted from the body, so they can only...

"Puff..." Chen Kan vomited several mouthfuls of blood in a row, all of which were black blood, all of which were impurities excreted from the internal organs.

However, Chen Kan didn't feel anything at all at this time because the pain was still going on. Now it was not just the pain, but it was also itchy. The itch coming from the bone marrow was more unbearable than the pain. Chen Kan endured it and would never let himself scratch it. Moreover, Chen Kan knew that this feeling came from the bone marrow and could not scratch it.

Chen Kan's body is now red and purple, and even steam is visible to the naked eye begins to emerge. These are sweat evaporated by the high temperature of the body. As for Chen Kan's clothes, they were destroyed by Chen Kan's internal energy long ago. Now Chen Kan is naked.

Chen Kan can see the rising blood vessels on the surface of his body. According to the body structure, the blood vessels we can see are venous blood vessels, and the blood flow is generally very small. What really transports blood are the arterial blood vessels that we cannot see.

But from Chen Kan's venous blood vessels that were rising now, you can feel the blood inside flowing rapidly. Now the internal energy has penetrated into the blood and it has begun to wash the blood vessels continuously.

Chen Kan's breakthrough came to the last level, which was the self-generating internal energy, which was the symbol of the first level of the Golden Bell Cover. Where did this qi come from? First, the completed external and internal qi enters the meridians of the body. This has been completed, and some of them must forcefully lead the qi into the body. This is the last level placed in front of Chen Kan.
