Mo Fan followed the master downstairs.

"This is it. Tao Tao said with his foot on the cement floor.

Mo Fan glanced around, this is the ordinary first floor, empty, the only difference is that the floor of Mo Fan's room is a wooden plank, and this is a concrete floor.

Mo Fan glanced at the ball in his hand and muttered, "Do you have to be so careful?

"That's right! It's going to burn!" The gluttonous and sensitive ear heard Mo Fan's words, and he replied, "But it's not the fire that burns, it's you!"

"What! I'm on fire!", Mo Fan shouted, "Master, why should this fusion fire be burned!"

Tao Tao said: "You will understand in a while, give me the fire." ”

Mo Fan grimaced and handed the fire back to the glutton.

Tao Tao took the ball, put it away first, and condensed a water ball with a diameter of fifty centimeters out of thin air, he carved a very complex circular formation with water, and placed a bunch of materials and spirit stones in several circles in the formation.

"Master, what are those things for?", Mo Fan pointed to the pile of materials he didn't know.

"You don't know the specific name, but it's simply used to save your life. ", gluttony said.

He took out a jade bottle and handed it to Mo Fan, "This is the pill you just took, called Xuanshui Dan, there is still one left in it, you can open it again when I want you to take it later, understand!"

Mo Fan took the jade bottle and nodded, he already had a very ominous premonition.

"Okay, don't talk nonsense, just stay in the eyes of the formation, and I'll do the rest. ", gluttony said.

Mo Fan nodded, walked into the middle of the formation and sat down, at this time, he looked like he was panicked on the surface, but in fact, his heart was also panicked.

Seeing that his apprentice was ready, Tao Tao twisted the ball, and after twisting the upper part open, a strong fire light emitted from the ball.

Gluttony threw the outer shell of the ball aside, pinched a handprint on the ball with one hand, and the fire slowly flew up.

Mo Fan saw clearly this time, this was a small flame that was still burning without combustibles, a fiery red outer flame, a red inner flame, and a pure black flame heart.

"Mo Fan, open your mouth, ready to swallow it!", the gluttony shouted.

"What!", Mo Fan shouted.

Seeing a good opportunity, Tao Tao directly manipulated the flames into Mo Fan's mouth.

Mo Fan's eyes widened: !!

Seeing a small flame fly into his mouth, Mo Fan was stunned, and when he reacted and closed his mouth, the flame had already flown into his mouth.

"Endure the pain, swallow the flame into the stomach, and after the flame is withdrawn into the meridians, and return to the dantian after a week!", Tao Tao shouted while activating the formation, and a steady stream of spiritual energy gathered towards the formation, and with the cooperation of the pile of materials that I don't know the name, the spiritual energy of heaven and earth was transformed into a gentle water aura with healing properties.

In fact, there is no need to be gluttonous, after the flame flew into Mo Fan's mouth, he habitually swallowed a mouthful of saliva, and the little flame came to his stomach very smoothly along his swallowing action.

The burning sensation caused by the heat travels from the mouth, to the throat, to the esophagus, and finally to the stomach.

It hurts! It hurts! It hurts!

Mo Fan felt that this pain was no less than yesterday's pain, and he felt that the organs through which the flames passed were burned and dried.

"Extract it into the meridians and run it for a week according to your exercises!", Tao Tao said.

Mo Fan was so painful at this moment that he couldn't even speak, so he could only do what his master said.

The flame is very small, but the meridians are even more small, every time a trace of flame is pumped into the meridians, Mo Fan deeply feels that the meridians are about to crush and break because of the high temperature of the flames.

"Hold on! You must hold back!", Tao Tao shouted on the side: "It's already this point, you have no way out, Mo Fan can do it!"

Mo Fan listened to his master's words and continued to endure the pain and pumped the flames into the meridians.

An hour passed ...

Mo Fan finally completed the transfer of the flame at the speed of a snail's slow crawling, although it was said that the long pain was not as good as the short pain, but Mo Fan didn't dare at all! Every time he moved a little distance, the body's pain response was so sharp that he wanted to cry, if he transferred it all in one go, it was estimated that he would faint, and the flames that were out of control could definitely burn him to the slag.

The cold sweat on Mo Fan's original forehead had been heated into hot sweat by the temperature on the surface of his body, and he inhaled a breath, and the rich water aura continued to nourish and restore the burned organs with his breath.

Next...... It was to use this flame to run in the meridians for a week, Mo Fan thought.

Mo Fan closed his eyes tightly, not realizing that his body surface had changed from normal skin color to pale red, as if it had been steamed.

Tao Tao stood outside the formation and looked at Mo Fan, he paid close attention to the changes in his apprentice.

He found that Mo Fan's body had begun to emit white mist because of the rise in temperature.

He clenched his fists: it should hold on!

Mo Fan put aside all distracting thoughts, forcibly endured the burning sensation of not paying attention to the meridians, and began to cultivate.

Outcome...... The speed of this flame is several times faster than just now, there is no way, the meridians and nerves are extremely sensitive, and every time they are scalded, they must move forward a little, just like getting extremely hot items in winter, it is impossible to keep in contact for a long time, and only constant exercise can reduce the damage of heat to themselves.

At this moment, the meridians that Mo Fan runs have spread all over his body, but it will take a long time to go through all the meridians that need to be run.

Although he hadn't finished running for a week, Mo Fan already felt that his whole body was as hot as staying in the flames.

In fact...... He guessed right.

From the glutton's point of view, since Mo Fan started to run the flames, the pores on his body began to erupt into flames, one part after another, so the gluttony could clearly see which area of the body the flame was running at this moment.

Mo Fan's clothes had been burned at the moment, and only a vest transformed by a magic weapon was still in its original state.

After another few dozen minutes, Mo Fan could no longer bear the effects of the high temperature.

"Eat the pill!", Tao Tao noticed Mo Fan's strangeness and shouted loudly.

Mo Fan opened his red eyes, quickly opened the cork of the jade bottle, put the mouth of the bottle to his mouth, tilted his head back, and the pill rolled down into his mouth.

As soon as the pill was ingested, it burst out with an extremely comfortable coolness, which spread all over the body, and the previous high temperature burning sensation was also very effective in alleviating.

Mo Fan put the bottles aside, ready to finish the week while the effect of the medicine was still there.
