Hearing Yun Fei's words reveal the source of his injury, the Tai Demon Bear couldn't help but be surprised, then nodded, and said slowly: "Back then, although I used the Tai Demon Fist to defeat the Golden Head Fox unexpectedly, that guy's bloodline was extremely peculiar, and when the Xuan Qi in my body was exhausted and weak, the blood poison it left in my body suddenly exploded, polluting eight tenths of the meridians in my body. ”

"Blood poison, is it those red substances attached to the meridians?" Yun Fei asked, he had just probed and found a large number of red substances attached to the meridians of the Tai Demon Bear, but it didn't seem to be anything special.

The Demon Bear nodded, "That's right, that's the blood poison." Usually there is nothing unusual about staying there, but when the Xuan Qi flows through those meridians, it will unconsciously be contaminated with its toxicity. In the long run, the Xuan Qi in my body will always be completely polluted by blood poison, and I will become a bloodthirsty monster. So ......"

"So you completely gave up the cultivation of Xuan Qi and concentrated on the physical body. Yun Fei continued, and his understanding of the Demon Bear was refreshed again. Even if it is reduced to a bloodthirsty monster, with its strength, it can still easily occupy the medicine mountain, but for the other demon beasts in the medicine mountain, that day will be miserable.

"It seems that this guy took the initiative to give up Xuan Qi cultivation for the sake of the Medicine Mountain Demon Beast. From this point of view, the talent of this Demon Bear is a bit terrifying, in a hundred years, with simple cultivation, he can improve his physical strength to the eighth rank of gods, which is completely different from Xuanqi cultivation. Yun Fei muttered to himself.

"You asked me about the Xuan Qi grade, but it's because you've found a way to get rid of blood poison?" Yun Fei asked.

The Tai Demon Bear nodded hurriedly: "Judging from my experience of fighting with this blood poison for many years, as long as the Xuan Qi grade is high enough, it will not be contaminated by the blood poison and will be dispelled bit by bit. Judging from my experience, the Xuan Qi grade must be at least seven grades before it is possible to expel the blood poison. ”

"Is the Xuan Qi condensed by the Seven Rank Exercises?" Yun Fei still agreed with the conclusion reached by the Tai Demon Bear. Seventh-rank and above Xuanqi does possess a lot of incredible power. Just as the strength of a high-level godman far exceeds that of a sixth-order godman, this is a qualitative leap.

"What's going on?" asked the Demon Bear.

Hearing this, Yun Fei slowly shook his head and said, "Lord Tai Demon Bear, I can't do anything at the moment. ”

"You're kidding me?" said the Demon Bear's tone.

"Slow and slow, you can listen to me. Yun Fei hurriedly waved his hand, signaling the Demon Bear to calm down, "I just said that I can't do anything at the moment." In this way, Lord Tai Demon Bear, you and I will sign a gentleman's covenant, you will teach me the Tai Demon Fist, at least three months, at most a year, Yun Fei will definitely return here to heal your old wounds!"

Yun Fei naturally had his considerations when he said this, and in two months, it would be time for Luo Cheng to agree to ask for the Heart Protector for him. If the Heart Protector Grass really had a miraculous effect, and Yun Fei really re-cultivated the Qi Fusion Heavenly Yuan Gong, then he would naturally return here to heal the Tai Demon Bear, and if the Heart Protector Grass had no effect, then Yun Fei would have to go around again for medicine to heal his injuries. If you haven't found that kind of miracle medicine after a year, half of the three-year period agreed by the old ghost has already passed. Then Yun Fei could only give up cultivating the Qi Fusion Tianyuan Gong and concentrate on tempering his body. When the time comes, Yun Fei will come back here and teach the Tai Demon Bear a book of seven-grade exercises, and let it practice on its own, which is also the biggest reliance that Yun Fei has so much fear.

"Why should I believe you?" said the Demon Bear uncertainly.

Yun Fei shook his head slightly, and said with a smile: "Lord Tai Demon Bear, Yun Fei is not an ungrateful and untrustworthy person. ”

"Roar...... Okay!deal!" The Devil Bear grinned and happily agreed.

Just like the female spotted tiger said, after the past few days of fighting, the Tai Demon Bear and Yun Fei have developed that very delicate hostile relationship.

"The key to the Tai Demon Fist is very simple, there are only four words - want to raise and suppress first! First compress the power in the body, and then burst out in a very short period of time in the form of a fist swing at extreme speed!"

Yun Fei listened carefully to the Tai Demon Bear's explanation of the key to the exercises of the Tai Demon Fist, and there was a hint of realization in his eyes: "Is this the reason why the Tai Demon Bear is sluggish every time he performs this move? It turns out that it is not the momentum that is sluggish, but the momentum is compressed." ”

"The power of the Tai Demon Fist mainly depends on two points, the first is the upper limit of the power you can compress, and the second is the speed at which you swing the punch. No matter which point of it, there are extremely strict requirements for physical strength, I don't worry about your physical strength, the only thing to worry about is the strength of your arm bone, I don't know if it can support such a strength of strength. "Tai Demon Fist is no matter how big or small, and he tells it one by one, but he is an extremely qualified teacher.

Yun Fei nodded secretly when he heard this, "Indeed, although the strength of my physical body is constantly improving, the cultivation of human bones is not emphasized in the Eternal Immortal Body. Whether it is compressing the power or throwing punches quickly, there are not low requirements for the arm bones, which is a difficult point. ”

"Lord Tai Demon Bear, I don't know how you exercised the strength of your arm bones when you studied Tai Demon Fist back then?" Yun Fei asked.

The Demon Bear smiled bitterly, "What's the solution, it's just that the bones are broken too many times, and they will naturally become hard." ”

Hearing this, Yun Fei's face suddenly turned slightly pale, this sentence is simple, but the pain of broken bones is not something that anyone can bear.

"Okay, just say that you don't practice fake tricks, I have already taught you everything that should be taught, and the rest is up to you. Remember, if you want to practice the Tai Demon Fist well, it's actually very simple, just break the bones a few more times. The Demon Bear commanded lightly, and then turned around and lay aside.

Yun Fei showed an extremely ugly smile on his face, and after breathing slightly, he began to compress the power in his body according to the law of the Tai Demon Fist.

With Yun Fei's movements, he felt as if he had been seriously injured, and the originally majestic momentum around his body suddenly declined, exactly the same as when the Tai Demon Bear used the Tai Demon Fist.

"Yo, I'm learning pretty fast. "The Devil Bear turned his attention here.

Yun Fei's face turned red, desperately squeezing the strength of his whole body, letting them slowly gather towards his arms.

Suddenly, an extremely crisp "cluck" sound came from his body, Yun Fei's complexion changed, and a sudden pain appeared in his mind.

"Ah...... It hurts. Yun Fei couldn't help but scream, the power in his arm suddenly dissipated, and Yun Fei lay on the ground like a loss of strength.

"Haha, I tasted it. It seems that this is the only way to go today, you should first take a good breath, and with your resilience, you should be able to try again tomorrow. Don't be in a hurry, the cultivation of the Tai Demon Fist is in a hurry...... Eh, what are you doing?" the Demon Bear's self-talk stopped abruptly, and it watched Yunfei's movements in a daze, and was speechless for a while.
