The old man's dantian was obscured by a layer of hazy mist.

At first, Zhang Bairen thought it was the internal force defense of the old man Tianxin's own dantian, but he found that the mist was very domineering and weird, and it was incompatible with the internal force wandering in the meridians.

In other words, it is devouring the internal forces in the meridians.

"This is the weird internal force that Senior Bao said?" Zhang Bairen whispered in his heart.

His mind was able to sink into it with the internal force, and now the internal force he entered the body of the old man of Tianxin was only as little as a finger, and it was not at all more than that strange internal force.

It's not that he doesn't want more internal force to invade it, it's just that the damage to the meridians of the old man Tianxin is too serious, and he is worried that any more external internal force will be a burden to the old man.

Zhang Bairen began to control the internal force, turning into a screen in the sky and enveloping the old man's dantian in Tianxin.

Fortunately, although the old man's dantian was huge, the incomparably thin demonic internal force still wrapped it.

At this moment, even the internal force in the meridians can't get close.

After the demon's internal forces approached, those strange internal forces seemed to be stimulated all of a sudden, and they became manic.

As soon as it went berserk, it began to impact, and it seemed that it also knew the strength of the demon's internal force, so it didn't dare to rush outside, so it had to pour into the dantian.

"Uh~~"

The old man of Tianxin screamed miserably, and the whole person bent up, like a bent shrimp, and his legs were staring high. His deep-set eyes widened suddenly, as if they were about to pop them out.

"Senior brother!"

Mr. Guo was so shocked that he was about to stretch out his hand to play the piano.

"Hmm!"

The old man of Tianxin jerked up left and right, signaling him not to move.

At this time, Zhang Bairen had already closed his eyes and devoted himself wholeheartedly, he was sweating profusely, and even the fingers that pinched the old man Tianxin were sweating.

The old man of Tianxin gradually became soothed, and the whole person lay flat again, but his eyes were open, as if he was looking at the ceiling, and occasionally he could see what he seemed to be fighting with.

In the old man's body, the old man had completely closed the dantian, and he was still preventing external internal forces from entering it.

Zhang Bairen is constantly using his demonic internal power to assimilate that strange internal force, as long as he assimilates it, he can take it away and solve the problem.

It's not that he doesn't want to be directly brought into the demon space in one go, it's mainly that this internal force almost grows in the body of the old man of Tianxin.

If he wants to take away this internal force, it is equivalent to taking away the old man's dantian.

In this way, the old man is also a wasted person when he is better, and without strong skills to protect him, the injury will break out immediately, and the old man will die!

The minutes ticked by.

Zhang Bairen's back was already wet with sweat, and even his hair was wet, clinging to his back.

Finally, half an hour later, Zhang Bairen's internal force completely assimilated the strange internal force, and then began to guide them back to his body, and he sucked it into the dantian to strengthen his body.

At this moment, Zhang Bairen's internal strength was also a little stronger. Although it has not yet reached the middle stage of condensation, it is no longer as weak as when it has just broken through to the early stage of condensation.

The old man had already fallen asleep, and Zhang Bairen withdrew his hand.

"Bairen, how is my senior brother?" asked Mr. Guo hurriedly.

Although he was asking, his hand had already caught the pulse of the old man, and his consciousness sank into it in an instant, investigating the situation.

Zhang Bairen didn't answer, he sat cross-legged on the ground, running the demon code, and he had to completely absorb this internal force.

After a while, Zhang Bairen got up, and Mr. Guo also stood up, his face full of joy.

"Haha, Senior Brother's internal force is full of meridians, and the internal force is full of vitality, and there is no longer that weird and domineering internal force in the dantian. Moreover, his internal force automatically drove my internal force out. ”

Mr. Guo was like a child, dancing excitedly, and almost threw his frost piano.

"Haha, Bainin, thank you. Mr. Guo held Zhang Bairen's arm and couldn't help but burst into tears.

Zhang Bairen shook his head and said, "Seniors don't have to be polite, I just happen to know this kind of kung fu." ”

He said that this is kung fu, but he didn't say that it was a gong, but he didn't want to cause unnecessary trouble.

Mr. Guo didn't care, he only cared that Old Man Tianxin was fine. He hurried to the entrance of the cave and greeted Bao Renjie, who was guarding not far away.

When he entered the cave again, Bao Renjie's footsteps were a little faster, and when he came to the cave, he also gave the old man Tianxin a pulse.

"Hey, my brother's internal force bounced me out. Bao Renjie let go of his hand, but he was very happy.

The two of them naturally thanked Zhang Bairen again, and almost knelt down. After that, Bao Renjie immediately went to get some healing pills.

Seeing the two of them in a hurry, Zhang Bairen said on the side: "Two seniors, I don't think there is any need to make a big deal about this matter!"

Both of them were stunned, they were still planning to hold a feast, after all, after the old man Tianxin recovered, it would be a great joy, and it would be able to deter the heroes!

Zhang Bairen said with a smile: "The old dean's recovery is naturally a gratifying thing." But for many people, that's not a happy thing. ”

What he said was a little vague, but both of them were understanding people, and they woke up in an instant.

Yes, the old man of Tianxin was wounded and dying by the enemy, this is the news that everyone in the Netherworld and the Ancient City of Ten Thousand Ancient Cities.

When the news of the old man's recovery spreads, all he does is to startle the snakes, so that the people of the Netherworld will hide deeper, and they will find an opportunity to make a comeback.

However, if you can lure the enemy deep and expose them all, with the strength of the old man of Tianxin, and lead the strong people of the academy, you will definitely be able to repel the strong enemy and defeat all the people in the Netherworld.

Bao Renjie patted his head and said, "Look at my head, under the surprise, I don't think as much as a junior." ”

Mr. Guo smiled: "It's natural that you are not as good as him, Bairen is not only outstanding in talent and strength, but also amazingly talented." He's a real man and a man, how can you compare to him with that little bit of brain?"

Bao Renjie hurriedly said: "Yes, yes, I'm not as good." ”

Then there was a long laugh, very happy.

Old Man Tianqin stood up and said, "Bairen, although I have been taking care of my senior brother all this time, I have also heard a lot about you. Your combat power far surpasses that of your peers, but you are more than fierce and not soft. Kung fu requires both rigidity and softness, and during this time, you might as well learn the piano from me!"

Zhang Bairen smiled: "Senior, if it's a sonic attack, the junior also has a trick that can do it, and this piano doesn't have to be ......."

"You're underestimating people who use musical instruments as weapons. Mr. Guo waved his hand and said, "Sonic waves don't have to kill, the most important thing is to achieve the goal!"

With that, he stroked the surface of the piano, and a delightful sound popped out.

Zhang Bairen felt a gust of spring breeze, and his body couldn't help but tremble a little.

The sound of the piano changed again, and a gust of hot wind hit, and Zhang Bairen felt as if he was walking in the hot summer.

The sound of the piano has changed again, two changes in a row, and Zhang Bairen has gone through the four seasons from spring, summer, autumn and winter. It wasn't until the sound of the piano stopped that he recovered, and his eyes sparkled.

"Now, do you think that sonic power can only be used to kill and injure?" Mr. Guo stood with his piano in his hands, smiling slightly.
