Old An observing Chen Feng's expression was very concealed. When he saw that Chen Feng's eyes were extremely clear and had no evil thoughts, he breathed a light tone.

Then, he smiled bitterly in his heart with some self-deprecating smile: "You, you have lived for thousands of years, but you are still testing a boy."

"It's really not true that you still have doubts. In the future, you must not doubt him."

It turns out that Old An said this, deliberately telling the preciousness of the Hell's heartless fire to test whether Chen Feng has evil thoughts.

What made him feel relieved was that Chen Feng did not have any intention of robbing the mysterious fire and taking it for himself.

This also strengthened the idea of ​​Old An: Chen Feng is a person worthy of entrusting and must teach him all his life's learning.

After Mr. An explained, he began to refine alchemy.

His hand shook slightly, and the Hell Wuxin Fire flew under the Qingmu King Cauldron and attached it to the bottom of the Qingmu King Cauldron.

And almost at the same moment, the firepower penetrated into the Aoki King Ding.

Chen Feng saw a cluster of flames instantly appearing inside the Qingmu King Ding.

The color is the same as the heartless fire in hell.

While moving, Old An explained: "The first step in refining alchemy is to extract spiritual medicine into spiritual liquid."

As he said that, he controlled the heartless fire of hell in the cauldron. The flames licked the spiritual medicine inside with great agility, and squeezed out the spiritual liquid in the medicine little by little.

No trace of medicine was burned, nor was there any trace of medicine.

Soon, the ten medicinal materials thrown into it were squeezed out, and the size of spiritual liquid was distributed on the wall of the Qingmu King Ding.

In the air, the fragrance of medicine is everywhere.

Then, Old An kept throwing the spirit herbs into the dragon head on the top cover.

Soon, more than a hundred spiritual herbs were thrown into it, and the spiritual liquid inside turned into a large ball.

However, there are all kinds of colors, and the medicinal power does not merge into one.

Old An explained: "What you need to do at this time is to temper the spiritual liquid into a spiritual pill."

"You must remember later that your energy must penetrate through the flames, like a hand, gently..."

While refining, Old An kept teaching Chen Feng this.

Chen Feng listened very seriously, and before he knew it, half an hour passed.

The alchemy has come to an end. With a clanging sound, the top cover suddenly jumped up.

Then, a pill, black and black, flew out of the Qingmu King's Cauldron and fell into the hands of the old man.

This pill is very strange.

Half of it is red, half of it is green, and the fragrance of medicine is everywhere. It makes people feel refreshed when they smell it.

And half of the air is filled with a fiery and hot air, and the other half is filled with vitality.

The dark veteran threw the pill to Chen Feng and said with a smile: "This pill is called Fire Mu Zhen Pill."

"After swallowing this pill, you can temporarily change the attributes in your body, allowing you to have the body of fire and wood attributes within one month, so that you can refine the pills."

"But, only one month!"

"After a month, this system will not only disappear, but will cause extremely severe damage to your body, and may even reverse your strength."

"Whether to eat or not, you can make your own decision."

Chen Feng swallowed it in one bite without hesitation and said resolutely: "Even if I pay such a price, I must eat it!"

"I must save Bai Shanshui and Xue Feng, and I must help Ling Xiao unseal the seal!"

An Lao laughed and said, "Okay, Chen Feng, I'm not wrong with you. You are indeed a person who values ​​love and righteousness."

"Since that's the case, today I will teach you the method of refining alchemy and personally help you refine Xiaohuan Dan."

Old An laughed: "By the way, isn't there a very interesting little guy around you? Why didn't she come out? Could it be that she was scared to see me?"

As soon as he finished speaking, Zi Yue suddenly floated out of Zi Yue's knife and appeared in front of Old Dan.

She snorted arrogantly: "I'm not afraid of you, the old guy?"

"Anyway, you are in the state of soul body, so you can't do anything to me. We two are not talking about the second one now."

"Haha!" Old An laughed, he seemed to like the quirky Zi Yue very much, and said:

"You little girl, although we are both soul bodies, I am older than you and have lived for thousands of years. You must respect me!"

Seeing that An Lao and Zi Yue got along very well, Chen Feng showed a smile on his lips.

He was actually a little worried just now. After all, Old An and Zi Yue both exist in the form of soul bodies. If they were hostile to each other, it would be really hard to deal with.

It would be embarrassing to get stuck in the middle.

Old An and Zi Yue had a while of their mouths. Not to mention, he really loved Zi Yue very much and kept smiling.

Chen Feng looked around and felt that Dan Lao was like an ordinary old man sitting under his roof, making fun of his granddaughter.

Old An looked at Chen Feng and said in a deep voice: "You can eat this Fire Wood True Pill now!"

Chen Feng nodded and put the pill into his mouth.

Then he felt an extremely hot force blooming in his mouth and then surged into his body.
