I have to say that the two have too rich ideas.

Lin Yang would not try medicine with a living person at all. Even if he tried the medicine, he would do it himself.

After all, only by realizing the efficacy of the medicine can you understand the shortcomings of the medicine.

"It's almost done!"

After some sorting, Lin Yang walked over with a large number of medicinal herbs, then jumped onto one of the cauldrons, hooked the lid with one foot, and threw the medicine inside.

When everything was ready, Lin Yang turned his head and said, "You can come here and make a fire."

"good!"

The two nodded.

Once the lid is closed, the firewood will begin to be lit, and then activate the energy to control the temperature of the flame.

"The temperature of this furnace of medicine needs to undergo 137 changes. I will tell you dictated it. It must be strictly controlled according to what I said. Do you understand? There is no deviation at all."

Lin Yang walked to another medicine furnace to prepare medicine and said.

"More than 130 changes?" Chen Nianhua was shocked and asked in surprise: "How long will this pot of medicine be refined?"

"Five hours!"

"What? Five... Five hours?"

"That means that during these five hours, we have to keep piping off anger and making fire?"

"Yes!" Lin Yang nodded.

"This is impossible! We will die in exhaustion!" Chen Nianhua almost roared.

"Control the temperature of the flame with qi is a fine job. With our current strength, it would be good to last for an hour. If you last for five hours? This is impossible!" Bai Nanli said gritting his teeth.

"How can you know if you don't try it? What's more, you are in the Xuanyi School Academy, in my territory. Here, if you want to die, it's probably not that easy!"

Lin Yang smiled slightly: "Don't worry, use your energy boldly! Even if you are exhausted, I will help you recover! I will guarantee your safety, but you must ensure that the pot of medicine is made safely. If something goes wrong, you may not be able to bear the consequences."

Speaking of this, his expression had become extremely serious.

The two of them trembled all over, and did not dare to hesitate, and immediately began to control the fire.

However, as they said, after only an hour, the two of them were sweating and panting, as if they could no longer hold on.

Lin Yang, who was practicing elixir alone here, saw that his fingers moved.

Whoosh swish swish swish...

Several silver needles flew over and pierced directly into the two of them.

In an instant, the qi veins of the two gradually became full and moist.

"So amazing!"

The two of them couldn't help but their eyes lit up.

"Nanli, I didn't expect that this small silver needle could make my qi veins continuously produce qi! This magic doctor Lin is indeed well-known!" Chen Nianhua whispered.

"It's really unique. In the age of the age, maybe we can use his silver needle to cultivate qi and improve our realm!" Bai Nanli whispered.

Chen Nianhua focused on the key point: "When practicing in the past, once it was exhausted, it would take at least one day to recover. However, with this silver needle, it could be filled in instantly. In this way, the cultivation speed has been increased by several times."

"Quick, keep urging your anger!"

"good!"

The two became serious.

Five hours passed so.

The two of them were still exhausted and collapsed on the ground.

At this moment, their bodies were wet. Even if Lin Yang urged the silver needle, they could not recover their qi.

They wished they could die now.

Lin Yang stood up straight, walked over, and opened the lid of the cauldron.

In an instant, a intoxicating fragrance filled the entire medicine room.

"The quality is very good, it seems that you have a good control over the heat." Lin Yang nodded with satisfaction.

The two looked at him powerlessly, unwilling to speak.

But Lin Yang took out two pills from it and threw them at them.

"Eat it."
