As the illusion crystal was continuously eroded, Han Tu's aura became stronger and stronger, and gradually, it was able to affect the flow of aura outside his body. This is a sign of breaking through to the eleventh layer of Qi training! It seems that as long as there are no accidents, these eleven layers can be regarded as nine out of ten.

But at this moment, there was a sudden knock on the door. Han Tu didn't want to pay attention to it, but the voice gradually became messy, and there was a tendency to become more and more intense, which made Han Tu, who was usually calm, gradually become a little irritable.

He opened his eyes and stared at the door, as if wondering what someone would choose to bother him when he broke through.

When most people break through, they will cause strong aura fluctuations. Others, when they notice it, will also choose to avoid it. After all, for disciples in the Qi refining period, it was common to break through more than ten times. If you disturb others to break through, aren't you afraid that the other party will interfere with you in the future?

But the person outside the door had no intention of stopping, but began to beat more violently.

As the wooden door continued to tremble, the closed iron lock gradually loosened. Finally, after a few breaths, the lock broke in half and fell to the ground.

At this time, Han Tu's eyes exuded a chill, and he originally thought that no one would affect his state of mind. But when he saw the person outside the door, he still couldn't help but be angry, and a mouthful of blood gushed into his heart and spurted out.

No, I'm afraid, it's a more serious dispersion of the spirit.

Thinking of this, Han Tu hurriedly adjusted his mentality, and after stabilizing his breath, he no longer paid attention to the person in front of him, but concentrated on breaking through.

The little girl outside the door was stunned for a moment, but quickly reacted, and after closing the door, she left alone.

Although Han Tu's eyes were closed, he still vaguely felt the other party's departure, and he couldn't guess the other party's thoughts for a while, so he could only leave it behind and make plans in the future.

Perhaps because he had suppressed it for too long, after spitting out a mouthful of blood, Han Tu felt much better and felt refreshed. This feeling hadn't appeared for a long time, and he hurriedly took this opportunity to try to break through to the eleventh layer of Qi cultivation again.

As a large amount of aura poured into the dantian, the position above the dantian vaguely seemed to form a vortex, which could absorb the aura more quickly while also providing the thickness of the aura.

This is a precursor to a cyclone that can be connected to break through the foundation building period. When this thing appeared on the dantian, Han Tu could finally be regarded as having successfully broken through to the eleventh layer of qi training.

It is only one step away from the final foundation building period.

It's a pity......

Thinking of this, Han Tu sighed.

This is just one step away, and there are more than a million immortal cultivators who are blocked......

Han Tu retracted his mind, and now he obviously had more important things. He came out of the room, leaned out half of his body to look around, and after making sure that no one was there, he returned to the room again.

He didn't want to have a second time for what he had just experienced, if it wasn't for the little girl who took away his Zhuji Dan, but someone else, maybe he wouldn't have almost broken the Dan and scattered his spirit.

Han Tu sat cross-legged on the bed and tried to guide the black pipe to the next breakthrough.

Since the beginning of the fifth layer of Qi training, all I can feel is the ability to increase the thinking ability of my brain and the air cushion that can support my short-distance displacement in the air. Other than that, the other abilities are only slightly increased by one order.

And the black pipes on his hands and chest did not show any effect. This is undoubtedly extremely disappointing for Han Tu, who has always relied on the black pipe.

It is precisely because of this that he is so eager to see if there is any new effect on this black pipe, which has undergone further changes.

Under the deliberate control of Han Tu, the black pipe began to make changes to the next stage. Fortunately, as Han Tu thought, all parts of the body have opened up black pipes, and it is still unrealistic to want to extend new black pipes again.

But the subtle changes that came from the black pipe made Han Tu unbearable to let go of his cultivation about the black pipe.

Just as Han Tu was focusing on the changes in the black pipe, night had quietly fallen. In the blink of an eye, four hours had passed. His advancement in the black pipe was even more time than it took to break through the eleventh layer of Qi training.

Just when Han Tu was about to lose patience, the black pipe finally had a noticeable change. The second-order black pipe, which was previously hidden behind the first-order black pipe, has been looming until it is used. Vaguely, there were signs of attaching to the first-order black pipe, and there was a tendency to merge.

He didn't know whether this change was good or bad, but at the moment, there was no other way.

Han Tu activated the aura, intending to further promote the fusion between the black pipes.

The night passed quickly......

The Dust Cutting Sect is one of the best sects, and it is one of the eight major sects that are famous far and wide. It is reasonable that such a sect has a place dedicated to providing low-level spiritual grass for its disciples.

The Herb Hall is in the inner town of the Dust Slashing Sect, and although his owner is an immortal cultivator, he likes to gather with mortals on weekdays to tell about his troubles.

What was even more surprising was that when facing immortal cultivators, his attitude was even worse.

On this day, he had already made an appointment with the neighbors to play chess, but suddenly a young man with a not very outstanding appearance and slightly dark skin because of his perennial appearance stopped him and asked to sell medicinal herbs.

He was not in a good mood, but after seeing the dozens of medicinal herbs of the young man, he was even more furious.

It's hard to imagine that an old man of nearly 100 would be furious because he was disturbed to play chess.

"Are you innocent to tease the old man, and where did you come from this pile of rags?"

"Elder Hui, these are the materials for Tsukidan, which were given to me by another elder. ”

Seeing this, compared to most people who had already guessed, this young man who was going to exchange medicinal herbs with the old man was the Han Tu who had just broken through the eleventh layer of Qi training.

And this is nothing, his biggest gain in the past few days is that he has finally completed the training of black bones in three days after continuous efforts day and night.

That's right, in the future, Han Tu will use black bones to refer to the black pipe that can transmit aura. When the two black pipes fused, Han Tu did not stop them, but helped them, so that they could be perfectly combined and show an appearance that was incomparably close to human bones.

It is precisely because of this that Han Tu calls these black pipes that exist in his body and resemble human bones black bones.
