The hot temperature in the Tianfen gas tower is really terrible. If you are not prepared, the heat drilled into the body is enough to roast the human body from inside to outside.

Of course, for mu Qingxiao, the temperature in the tower is just right.

He not only inherited the characteristics of Phoenix, but also retained the preferences of Terrans. Although he did not like hot things, he did not hate them.

Looking at the poisonous gas from the body of the little medical fairy, mu Qingxiao raised his hand, gently put it on her fragrant shoulder, closed his eyes and checked her situation.

At this time, in his sight, a strange flame appeared in the heart of the little medical fairy, which was beyond common sense.

The flame is invisible and not too powerful, but the heart is always the most vulnerable part of the human body. A little carelessness may lead to serious consequences.

The flame emits extremely high temperature and roasts the channels, bones and various organs of the little medical fairy. If this goes on, the channels and organs in her body will die soon.

The most important thing is that the poison gas in the little doctor's body suddenly became violent under the extremely high temperature.

Even, there was a trace of fleeing from the ordinary seal, and fled away from her body, afraid to stay more.

"We can't go on like this. This is the last time to strengthen the seal. We have to find a chance to go to the bottom of the tower, otherwise it will be difficult to do."

After that, mu Qingxiao's hands were sealed, and the yin-yang aura crossed into the body of the little medical fairy. He swam in the meridians, forcing the poison gas to finally gather in the lower abdomen.

"Seal!"

Just after the seal was set, the yin-yang aura formed an encirclement net to wrap the poison gas in her body. The ordinary seal was formed.

While yin-yang aura seals the poison gas, the poison gas is slowly invading the spirit gas. After all, the little medical immortal is not the carrier of Yin-Yang aura, and the disaster poison body is also breeding poison gas.

If Mu Qingxiao himself, the yin-yang aura in his body is endless, and it is not a problem to seal the poison gas forever.

"There is no condensed poison pill now. You can't condense the poison gas with your own strength. Although your strength is improving, the disaster poison body is still beyond your control."

The little doctor pursed her red lips and looked at him with a red face. A layer of sweet sweat came out on her jade forehead. The overflow of poison gas just now really scared her.

With that, mu Qingxiao stretched out his right hand and sucked into the little doctor's body. Then a twisted invisible flame was forcibly pulled out.

Looking at the invisible flame beating in the palm, the black divine fire flashed and died, and the invisible flame has been swallowed up.

When his heart was extinguished, the little doctor's face gradually returned to normal.

"Don't worry. You'll soon find a way to seal the poison body. With me by your side, you can practice at ease."

Hearing the speech, the little medical fairy nodded slightly, stepped forward, Zhen's head gently leaned against his chest. Only his warm embrace could make her calm down and get rid of the trouble of misfortune and poison.

The two hugged each other, which made the old students in the gas tower cast strange eyes one after another.

...

...

A moment later, mu Qingxiao and the little medical fairy strolled in the Tianfen gas tower.

At the bottom of this deep buried tower, only a section of the Tianfen gas refining tower at the top of the tower is exposed, but the area inside the tower is somewhat unexpectedly spacious.

Along the way, he found that only the space in the first floor tower was enough for 500 students to practice at the same time.

In the circular distribution of the tower space, there are also training rooms of different sizes.

Of course, the training rooms at this time are almost occupied by students, and some mahogany cards are hung above the doors of these training rooms.

There are three types: high level, intermediate level and low level, which correspond to the level of the cultivation room in the tower.

The higher the students enter the training room, the cost of fire energy remains the same, but the corresponding strength is required.

Otherwise, even if you rush in, you will be quickly thrown out by other students.

Therefore, if you want to get better cultivation conditions, you need to work hard.

Students with poor strength can only practice in the peripheral low-level cultivation room, while those with strong strength can practice in the intermediate or high-level cultivation room, with very different effects.

For example, in the low-level training room, the training speed of students can be increased by 20%, while in the intermediate training room, it is 40%, and in the high-level training room, it is 60%.

After long-term cultivation, the students will find that they have long been dumped by dozens of streets in the same period.

It is this situation that makes them work harder.

Without facing difficulties, human potential will never completely burst out, and what the college provides is this kind of alternative depression.

As long as it is repressed to the extreme, there will always be some completely explosive students and fast speed to catch up with the previously hard to touch strong ones.

...

...

With mu Qingxiao and the little medical immortal walking from east to south, it is not surprising that the more advanced the training room is, the closer it is to the central position of the gas training tower.

In the periphery, there are intermediate training rooms and lower training rooms in the periphery, which are neatly divided and clear at a glance.

The breath is getting closer and closer, and the divine fire is hungry and thirsty.

A few minutes later, mu Qingxiao stopped and looked forward along his line of sight. They had reached the most central position in the tower.

"Is it here?"

Looking at the bottomless black hole in his eyes, mu Qingxiao slowly walked forward a few steps and came to the edge of the black hole.

Looking down, it was dark until the end of the line of sight. There was no light. It was like a huge mouth that ate people. It was dark and strange.

The black hole in front of us seems to run through the whole Tianfen gas refining tower. If we were not covered by the spire, we could have a panoramic view of the bottomless black hole.

Standing on the edge of the black hole, you can obviously feel that the air here is much hotter than outside, and the only thing that provides such heat to the Tianfen gas tower is different fire!

The little doctor followed him closely, but he didn't feel any discomfort. He just took a careful look at the black hole and took back his eyes.

"Boy, this is not where you freshmen should come. Get out of here quickly."

Just as mu Qingxiao was thinking, an old voice sounded behind him, pulling him back to reality. The voice was a little familiar. It was the voice heard outside the tower earlier.

Turning around, an old man with both hands stood behind them. The old man's white hair and muddy eyes flashed a trace of fear when he looked at the black hole in the center.

Mu Qingxiao nodded slightly, took the little medical fairy away from the black hole, came to the old man and said, "are you?"

"I'm the tower keeper on the first floor of Tianfen gas tower. You can call me elder Yang. Look at you, is it a freshman this year?"

Elder Yang stroked his white beard and said in a flat tone.

It turned out to be the elder guarding the tower. No wonder he has the strength of the four star king. It seems that the lower he goes, the stronger the elder guarding the tower is. He really deserves to be a Canaanite college.

"Mu Qingxiao, I've seen elder Yang."

"Hmm? Are you mu Qingxiao, the famous freshman?"
