The old dragon

He chose the last room on the third floor near the spiral staircase. There are a total of nine rooms on the third floor, and the remaining eight rooms have already been selected by his brothers and sisters, so he has no choice.

But Su Huan is not picky, he thinks this room with a bad orientation is good.

And the room next to him happened to belong to Bai Susu, the eighth senior sister who was brought by the teacher to the outside world for training two years ago.

After resting for a while, I felt the soft big bed.

Su Huan forcibly turned over and got up.

He took out all the metamorphosis materials of the dragon snake lizard collected during this period.

Put everything on the coffee table in the living room.

After a while, Su Huan left two items and put the others away again.

And locked into the bumper in the storage room.

The bumper password was still not set at the beginning, Su Huan set up a simple eight-digit password shortly before again, it was her sister plus her own birthday.

The two remaining materials are the essence of dragon blood and the essence of wind and thunder.

"The last ingredient of the main medicine is missing. It's time to prepare the prodrug and let the dragon snake lizard swallow it." Su Huan muttered to himself looking at the two ingredients in front of him.

The way of transforming a dragon into a terrifying species is very different from that of a dangerous species.

The biggest difference is that the way of transforming dragons in the future of most of the horror species is no longer simply to collect the materials, consume and digest the materials all at once, and then complete the dragon transforming ceremony to complete the way.

Instead, according to a specific process, the materials should be processed and formulated into a transformation secret medicine for pets to take.

The purpose is to better integrate the characteristics of different materials, greatly increase the efficacy of medicine, and improve the success rate of controlling pets and transforming dragons.

If it is not formulated into a transformation secret medicine, it is still like the dragon snake lizard and the treasure hunting beast to transform the dragon, let the pet control the dragon directly by taking the materials, supplemented by the dragon transformation ceremony.

There is also the possibility of success, but the success rate is frighteningly low.

The metamorphosis secret medicine is divided into "main medicine" and "predrug".

Before taking the main medicine, the prodrug must be taken and fully digested to increase the success rate of the dragon transformation process after taking the main medicine.

The formulation of the main drug usually requires the use of the main material of the metamorphosis pathway.

For the preparation of prodrugs, auxiliary materials can be used.

As for the secret medicine for the dragon snake lizard to transform into a dragon wind thunder dragon snake, there are only two ingredients for the preparation of the prodrug, 2000l dragon blood essence and wind and thunder essence.

These two materials have been assembled.

However, considering that after taking the prodrug, the main drug must be taken within a period of time after the prodrug is digested and before the residual drug effect in the body completely disappears.

Otherwise the predrug will need to be re-taken.

So Su Huan waited until Gillian City, harvested two main ingredients again, saw the hope of getting all the ingredients of the main medicine, and then prepared to prepare the prodrug.

However, the effect of the dragon snake lizard's prodrug lasted for as long as half a year, Su Huan considered that the nest disaster would sweep across in four months.

He and his teacher stayed in the outside world for a maximum of three months, and had to return to the Gray Wilderness to deal with the next crisis that the gathering place would face.

If within these three months, the Dragon Snake Lizard can't get together the last material to complete the transformation ritual and transform into a dragon, then there is no need to worry about the need to take it again after half a year when the effect of the former medicine disappears.

This is why I chose to prepare the prodrug now.

Although there are only two kinds of materials for the preparation of prodrugs, suitable various utensils are required for handling the materials.

Not to mention anything else, it is the essence of wind and thunder. Ordinary glassware will be broken by the energy of the essence of wind and thunder almost as soon as it is touched.

Su Huan doesn't have the teacher's strange thing that has a fixed space, and can carry the special utensils of his laboratory with him.

Only Liber could be found.

After learning about Su Huan's intentions, Zheng Li was quite surprised, but he still took Su Huan to the basement of the villa. A small and complete laboratory with all kinds of experimental vessels appeared in front of him.

The test bench is made of special anti-corrosion alloy, which is very expensive.

Su Huan was quite surprised.

The specifications of this laboratory exceeded his own small laboratory by an unknown level.

Originally, he didn't ask Liber Villa if there was a laboratory.

After all, in Su Huan's view, as the owner of the villa, the teacher has no such needs.

He just asked where to buy suitable test equipment.

Prepare to set up a crude laboratory in your surprisingly large room for the preparation of prodrugs.

Unexpectedly, there is such a perfect laboratory in the villa.

"This is the laboratory left by your sixth senior brother Cen Qin. He stayed in Gilded City for a long time and set up this laboratory." Li Bo's expression was slightly sad and regretful, It seems that he has a deep relationship with that sixth senior brother.

"Can it meet your needs?" Liber asked.

"Satisfied, it's perfect." Zhou He nodded in satisfaction.

Li Bo showed a smile and said: "Then I will go to work first. Here is the key to the laboratory. From now on, this laboratory will be handed over to you, Su Huan."

"Thank you, Uncle Li." Su Huan thanked.

Just when Su Huan was processing materials in the laboratory in full swing, preparing to prepare the prodrug.

Zheng Li was standing respectfully beside Zhou He, and reported: "Master, I have handed over Cen Qin's laboratory to Su Huan according to your instructions."

Zhou He nodded slightly, looking at the sky outside the floor-to-ceiling windows, his expression was equally effective and he said sadly: "Well, this is the best use of everything."

"When I took Su Huan as my apprentice, his performance was amazing, but I lacked the simplest understanding of him, and even had doubts about his extraordinary talent, but I still decided to accept him as my disciple. Do you know why? ?"

Zheng Li shook his head.

Zhou He said with emotion: "Because I saw him at that time, it reminded me of Cen Qin. They are both equally talented and hardworking."

"Like me when I was younger."

Zheng Li also nodded in agreement and said, "Yes, sir, when you were young, you came to the Gilded City alone, and with your own strength, you made a big name in this city."

"Cen Qin is indeed very similar to you. He was also almost the same among the same-age drivers in Gilded City back then. It's a pity that God is jealous of talents."

"I just don't know if this Su Huan can reach the height of Cen Qin?"

Zhou He sighed slightly, his eyes were full of expectation and said: "It's better than worse, sometimes I'm afraid I won't be able to hold on."
