On top of a huge stone pillar in the stream, the surface of the stone pillar was shallowly covered by flowing water, and the touch was smooth and abnormal under the washing over the years, Jiang Yichen sat cross-legged on it, and the breath of the sun was not as hot as he imagined, feeling the warm breath under the bottom continued to be transmitted from the buttocks, and the whole body was wrapped by the breath of the sun, and soon, Jiang Yichen's forehead and back were already sweating.

Single-minded, calm and calm, hold the yuan and keep one, and enter the state of cultivation.

Cultivating internal strength, in short, is the process of refining and refining qi, refining qi and transforming gods, refining gods and returning voids to the void, and finally forming Zhou Tian in the body. If it is divided into levels and repetitions, then refining and refining gas is the first layer, divided into one to three, and those who refine the first layer are small successes.

Refining Qi and transforming God is the second level, that is, three to sixth, and those who have cultivated to the second level have already achieved cultivation.

Refining the gods is also the third layer, seven to nine levels, and after the cultivation of this layer is completed, it is a great achievement.

If we go one step further, it is the cultivation of the Void and the Harmony of the Dao, which can already be said to cultivate the internal strength to the tenth level of the supreme realm, generally speaking, it is almost difficult to cultivate the tenth level of the inferior internal strength mental method, after all, the exercises are relatively superficial and cannot reach the supreme height.

At the beginning of his cultivation, Jiang Yichen was at the top of refining and refining qi, gathering the essence in his body and the aura outside his body at the acupuncture points of the bearing pulp and the front top, mixing and condensing.

Gradually forgetting the perception of the body, the whole body is as soft and soft as a baby, comfortable and comfortable, as if it were dead.

Suddenly, as the cold qi refined became thicker and thicker, a trace of coldness arose in the jaw and the heavenly spirit cover, and gradually the cold became more and more intense, this cold breath was not good at all, even if it could be borrowed to resist the hostile invasion of this cold qi on the meridians around the body, Jiang Yichen's jaw and hair roots were already forming patches of frost.

With the deepening of cultivation, the cold qi ran along the meridians of the Du pulse from the front to the top of the back to the top of the back, Qiangjian and other acupuncture points, Jiang Yichen only felt that the top of the entire back of his head seemed to be sealed into an ice cave, and his jaw was frozen to the point of losing consciousness, his lips could not even be closed, his head was dizzy, and he almost wanted to fall.

This frost and snow true qi is really vicious and abnormal, he has just woken up from a coma and is so aggressive, in the end he still overestimates himself, if it were not for the pure yang eyes with this supreme yang breath to continuously provide himself with warm qi, I am afraid that he has been frozen into a popsicle, life and death are unknown.

It was only a moment of distraction, and the inside immediately changed, and the cold in the front and back began to invade the nose and the intracranial center.

Half an hour passed, and the sun was at the end of the day, bringing a lot of help to Jiang Yichen's cultivation in the external environment, sweating outside his body, and a chill in his skull, with some meaning of ice and fire. Under Jiang Yichen's continuous gritted teeth, he finally stabilized the cold qi on several acupuncture points on his head, which can be regarded as forcibly completing the first cultivation of the cold ice true qi.

Unwilling to procrastinate, striking while the iron was hot, Jiang Yichen desperately absorbed the Yang breath from the bottom of the quotation to fight against the cold qi, and extracted all the energy remaining in the meridians after taking the strong pill, and went all out to overcome the second weight.

With a muffled snort, blood overflowed from the corners of his mouth that couldn't be closed, and the blood was condensed into frost in an instant, Jiang Yichen couldn't help but smile bitterly, and thought to himself that he was still in a hurry, although he barely cultivated the second one, he consumed too much energy, almost causing the cold to backlash and hurt the roots.

At this time, it was already noon, the strength of the whole body was completely empty, and the stomach was empty, so today's cultivation could only end here.

Raising his eyes, he moved his gaze to the gazebo not far away, only to see that the two old men were still waiting for him, and he didn't know if he had eaten, so he didn't want to go, so he got up and hurried over.

After having lunch with the second elder, Jiang Yichen did not continue to cultivate, it is not a good thing to be in a hurry, not to mention that he is still seriously injured and newly recovered, and his body is still weak, and the second elder does not allow himself to be too aggressive.

Jiang Yichen can afford to put it down, knowing that the cultivation of internal strength is not an overnight thing, so in the afternoon after the rest, he no longer thinks about the cultivation of internal strength, but relaxes himself wholeheartedly, and goes to talk to the second elder, the second elder is very kind and is an old man, rich in experience and knowledge, if you don't take this opportunity to ask for more teachings and learning, I am afraid it will be difficult to have such a good opportunity in the future.

Cheng Yin has a lot of experience in the study of gossip metaphysics, and seeing that Jiang Yichen, a young man who is just starting out, has such a desire to learn and learn, he does not hesitate to give advice. With Cheng Lao's on-demand broadcast, Jiang Yichen undoubtedly has a deeper understanding of the Qimen Dunjia technique taught by Xuan Xiao, if he can cultivate his internal skills in the future and no longer rely on additional weapons, this unpredictable Eight Dunjia Sword Technique will undoubtedly be his sharp weapon to deal with the enemy on the spot.

Divine doctor Weng Zhenhuai naturally has a very high attainment in medical skills and pharmacy, and Jiang Yichen naturally made a pharmacological consultation with Weng Lao, and even learned the refining of boiling blood powder. The pharmacology of Boiling Blood Powder is similar to that of Vigor Pill, which uses external force to make the blood boil in the body and accelerate the internal circulation, so as to achieve a strong boost to the essence and spirit, that is, the so-called surging effect of blood, which is suitable for taking in battle.

In addition to discussing medical pharmacology and gossip metaphysics with the second elder, the second elder took the initiative to grant Jiang Yichen the principle of health preservation, of course, not to let him follow the two to retire, but to better recuperate.

In the evening, under the instructions of the two old men, Jiang Yichen rested early and fell asleep early, recuperating for the next day's cultivation.

After three days like this, the young man's body gradually recovered as before, and even more energetic than before, and the cultivation of internal strength has also entered a lot of realms, and it is already a small success, so progress can be regarded as a healthy step for Jiang Yichen.

However, when breaking through into the fourth layer, the cold qi had to condense at the acupuncture points near the lungs and back, and this is the root of Jiang Yichen's tuberculosis, therefore, Jiang Yichen was also more cautious, and gathered most of his strength to resist the cold and ice breath, but due to the excessive loss of power, he had no strength to impact the breakthrough, and he was exhausted and fainted and fell to the ground after failing to succeed.

......

Weng Zhen Huai guest house.

"Ahem...... cough cough cough ......" Accompanied by his own coughing sound, Jiang Yichen, who was asleep in the bed, woke up, still felt that his breathing was blocked, and hurriedly got up and crossed his knees to regulate his internal breathing.

According to what the second elder said, in terms of his physical condition, he must cultivate at least to the fifth level to control the cold qi in his body, and when he cultivates to the sixth level, he can control this frost and snow true qi, and according to the current situation, I don't know if he can survive it.

Just as Jiang Yichen was frowning, distressed by his own weakness, there were footsteps and conversations from far and near outside the door.

"After all, it's still unsatisfactory, are we in a hurry? This is Weng Lao's voice.

"The cultivation of internal strength should be gradual and gradual, so swallowing dates, this child is not talented, it is already a good result to break through the first layer in three days, and then force himself to break through like this, I am afraid that the extreme will be reversed, no, when he wakes up, I have to make it clear to him, if I continue to cultivate like this, I have to take his life, and at that time, we can't help it." This is naturally the voice of Cheng Lao.

"It's time to slow down, and I'm in favor of letting him rest for a day or two. Weng Zhenhuai said.

"Well, let's wait until he wakes up. Cheng Yin said.

Since it was the joint suggestion of the two elders, although it was a mandatory order, Jiang Yichen did not dare to object to it and complied with it.

During the two days, he no longer touched the matter of internal cultivation, paid attention to recuperation, and helped the second elder take care of the courtyard by the way, and moved his muscles and bones.

After two days of recuperation, although the injury healed, but because of the cultivation of frost and snow true qi, he would feel dizzy every day, according to the second elder, if it were not for the cultivation of internal strength to the sixth level, the cold qi in Jiang Yichen's body would be relatively concentrated in the skull, which would have an impact on his mental state, and the only way to solve the problem was to speed up his cultivation.

On the sixth day after the coma shape, Jiang Yichen tried to break through the fourth layer again, and at the critical moment, his lungs were cold again, and he coughed wildly, but fortunately, the breath of the Yang that emanated from the eyes of pure yang at noon was stronger, and finally helped Jiang Yichen get what he wanted, and the fourth level of frost and snow true qi was completed.

After resting, in the pavilion in front of Weng Lao's house, Jiang Yichen was standing aside and observing the game between the two elders, but he saw a person running on fire.

The person who came was Wang Shide, who was seriously injured after the fierce battle at the fork that day.

"What's the alarm?" Seeing Wang Shide's panicked expression, Cheng Yin threw away the chess pieces in his hand and asked.

"The cardinal is in a hurry, there is an enemy to cut off the beard!" Wang Shide said hurriedly.
