The daughter of the emperor was reborn and was spoiled by the sickly prince.

To make medicine, one needs 108 kinds of the most poisonous poisons in the world, and they must be carefully mixed according to the principles of mutual promotion and mutual restraint before they can be made.

Aiqi swore that she would never let anyone else know about this.

Therefore, she had to prepare the herbs herself.

In the process of refining medicine, the order of using each poison and medicine is crucial. Any mistake will result in all previous efforts being wasted and even endangering Gu Mingzhao's life.

Therefore, Liao Qinglan naturally did not feel comfortable leaving this kind of thing to others.

She was with Aiqi every day, preparing the necessary poisonous insects and poisonous herbs together to ensure that every step was foolproof.

The two of them worked together in Crescent Bay for more than half a month before they prepared all the materials.

After all the preparations were completed, the three of them agreed on a time and sneaked into the secret room of the Five Immortals Sect under the cover of darkness and high winds.

The secret room is hidden in a cave with a heavy-looking stone door at the entrance.

The entrance of the cave is surrounded by dense ancient trees and fog. It is difficult to find this place if you just pass by.

Ai Qi took out a jade bead and embedded it on the stone door, and the door opened in response.

"Come in quickly."

After entering, there is a huge and empty cave, and every corner inside can be seen at a glance.

A strong smell of herbs wafted into the air, and a few oil lamps flickered with faint light, creating a very strange atmosphere.

There are many shelves around the secret room, and each shelf is filled with bottles and jars.

And in the middle is a huge pool.

This pool can accommodate one hundred people at the same time and should be used to soak medicine patients in potions.

The water in the pool was dark black, with a faint luster, as if it swallowed up all the light.

Liao Qinglan suddenly screamed "Ah", lost her balance and almost fell into the pool.

Gu Mingzhao was quick to move and quickly stretched out his arm to hold her firmly.

"What's wrong?" Gu Mingzhao frowned and asked with concern.

Liao Qinglan's face was pale and her legs were a little weak. She held Gu Mingzhao's arm tightly and tried to support her body.

She stared at the surface of the pool: "I... I just saw something in the pool..."

The words came to my lips, but I couldn't say them.

Her stomach churned and she couldn't help but dry heave.

Gu Mingzhao took a look at the pond and understood.

Ai Qi said nonchalantly, "It's just bones, don't make such a fuss. Refining medicine is a life-threatening business, so it's normal to see bones and corpses in the pool."

Gu Mingzhao gave Ai Qi a warning look, patted Liao Qinglan on the back, calmed her down, and tried to divert her attention elsewhere.

"The hole is so small that it can be seen clearly from the outside. What if someone comes in and finds us?" Gu Mingzhao asked.

Ai Qi said: "There are only two jade beads that can open this place. One is in the Elder Hall, which is the one in my hand. The other is in Feng Wan's hand, and Feng Wan will not come here."

Gu Mingzhao nodded: "Having said that, we still have to hurry up."

Liao Qinglan listened to them talking and recovered from her shock. She began to help Ai Qi prepare various medicinal herbs.

"Master Gu, the Five Immortals Sect's medicine refiners will select one hundred and eight extremely poisonous substances, and divide them into fifty-four for oral administration and fifty-four for immersion according to pharmacology. Each time, they will take one substance orally, and then soak in a medicinal liquid that conflicts with the substance. When the two medicinal properties cancel each other out, it means that drug resistance has developed, and they can move on to the next one. Once you survive fifty-four rounds, you will have developed the body of a medicine man, and from then on you will be immune to all poisons." Ai Qi explained to Gu Mingzhao.

"How long did it take to become a medicine man in the past?" Gu Mingzhao asked.

"It can be as short as three months or as long as half a year."

"It takes too long. Let's finish the test within a month." Gu Mingzhao said lightly.

"How is this possible!" Ai Qi blurted out, "Are you going to take two a day?"

"Why not?"

"No one has ever been able to withstand such a strong drug effect!"

"Then I will be the first one."

Liao Qinglan also felt that this idea was too radical: "A Zhao, it would be safer for us to take it slow."

"You understand pharmacology, but I understand human nature better. The longer we stay here, the more danger we will be exposed. If the people in the Five Immortals Sect find out, the consequences will be disastrous."

"But..." Aiqi wanted to say something else.

"No need to persuade me anymore. It's my own body, and I know my limits. If I can't bear it, I'll tell you."

Liao Qinglan and Ai Qi looked at each other and decided to improvise later.

Ai Qi took out a bottle, checked the name and smell of the poisonous weed against the notebook, and then handed it to Liao Qinglan.

Liao Qinglan checked it again, and after confirming that it was correct, she poured the liquid in the bottle into the sink.

The pool suddenly made a gurgling sound, as if countless lives were shouting and struggling in it.

"Next is oral administration." Ai Qi took out another medicine bottle and handed it to Liao Qinglan after checking it, just like before.

After Liao Qinglan got the medicine bottle, she did not rush to give it to him, but asked him to take off his clothes first.

Liao Qinglan held a silver needle in her hand and looked at Gu Mingzhao intently as she inserted the needle into the acupuncture point on his chest.

By doing this, acupuncture can be used to protect his heart meridians, ensuring that the toxic impact will not cause his qi and blood to attack his heart.

After the acupuncture was completed, she handed the medicine bottle to Gu Mingzhao and watched him take it intently.

After taking the medicine, you must immediately jump into the medicine pool to prevent the poison from spreading.

His body also began to change unconsciously.

The skin on his body turned red, as if it was burned by fire.

His brows were furrowed and sweat was pouring down, but he didn't make any sound.

Pain attacked him from all sides, making it almost impossible for him to breathe.

He closed his eyes, frowned, held the edge of the pool tightly with both hands, and tried his best to keep his breathing steady.

The poison in his body and the venom in the pool began to fight each other, and the two forces collided violently in his body.

Gu Mingzhao felt as if all his flesh and blood were being torn apart, and the pain was so severe that he almost fainted.

His strong body was trembling in the medicine and his face was abnormally red.

Liao Qinglan and Ai Qi both looked at him nervously.

After a long period of suffering, Gu Mingzhao finally felt that the two forces in his body began to gradually merge.

The body was slowly recovering and the burning sensation was gradually disappearing.

After opening my eyes, I saw Liao Qinglan's concerned gaze.

Ai Qi and Liao Qinglan both breathed a sigh of relief.

"A Zhao, how do you feel?" Liao Qinglan asked.

"I'm fine. How long did it take?"

"One hour." Liao Qinglan helped Gu Mingzhao walk out of the medicine pool. "Rest for a while and eat something. We can use the second one later."

Gu Mingzhao pushed away the steamed bun she handed over: "No need to rest, let's start now."

Seeing that except for his face being a little paler than usual, his other conditions were the same as usual, Liao Qinglan nodded and indicated that he could continue.
