The Praetorian Guards were stunned for a while when they heard Yun Chen's voice, and then quickly removed their hands on the sword, clasped their fists and saluted, and the person at the head stepped forward and asked, "Your Majesty, why is it late, do you have anything to do?" ”

"I have something to do to go to the Tibetan Medicine Pavilion, you continue to patrol, you don't have to follow."

"Yes" Although they didn't know why Yun Chen was going to the Tibetan Medicine Pavilion to do it late, they still didn't ask.

The surroundings are silent, because during the cold winter wax moon period, even the small animals in nature have no sound. Only the faint footsteps of Yun Chen could be heard.

The Tibetan Medicine Pavilion Li Qianyun Hall was a little far away, and Yun Chen walked along the palace road for a while before he reached the Tibetan Medicine Pavilion.

Because the Tibetan Medicine Pavilion needs a key to open, it is not afraid of being stolen by others, so there is no one guarding it outside.

I took out the key and opened the door and walked in. Because of this Tibetan medicine pavilion, the inside is very clean, but it is very cold because of the sun that has not been seen for a long time.

This Tibetan Medicine Pavilion contains the elixirs collected by Yunguo for nearly a thousand years, with a wide variety and huge quantity. When I came in the morning, I didn't take a good look because I was in a hurry, but now I have the opportunity to take a closer look.

After taking a closer look, I saw boxes on the shelves, and the names of the spirit grass were written on them.

Yun Chen took out a product of alchemy cheats and looked for the elixir he needed according to the pill recipe inside.

Yun Chen found the second floor from the first floor, and it took a long time to find all the spirit grasses that he wanted to use.

Because she was trying to alchemy, she took dozens of copies of each spirit grass.

With the elixir in hand, I can't wait to give it a try. walked out of the door, took the key, and tiptoed the ground, and returned to the Qianyun Hall in an instant.

As soon as he returned to the dormitory, Yun Chen immediately moved his mind to enter the Qinglian Realm and walked into the Fengfei Nine Heavens.

There were six secret rooms in Feng Fei's Nine Heavens, and Yun Chen planned to transform them all for different purposes.

Walking into the first room, I took a look, and moved the tables and chairs inside to a simple alchemy room.

He put the alchemy furnace that had just come from the second floor of the Tibetan Medicine Pavilion on the table, took out the spirit grass and placed it next to it in different categories. Spread out the alchemy cheats, took a look at the spirit grass needed to refine the simplest pill, and then selected the elixir to be used from the many spirit grasses.

Alchemy requires spiritual fire, and this is thanks to the fire phoenix. The fire phoenix has carried the natal spiritual fire since it was born, and Yun Chen, as its deed owner, can naturally use it.

Moreover, the natal fire of the ancient divine beast is powerful, if it is used well, it can increase the purification and fusion of the elixir, making the elixir more pure and more valuable.

The required materials were all prepared, and Yun Chen seemed to start alchemy at a glance at the process of alchemy.

First of all, the spirit grass is purified to remove impurities and leave the essence part. However, Yun Chen purified it a few times, and felt that the purity was not enough.

He frowned and pondered the steps of purification. Suddenly, her eyes lit up, she knew what was wrong, when purifying, the use of spiritual power should be from the outside to the inside, the movement must be slow, not overnight, otherwise some parts can not completely remove impurities.

Finding the mistake in purification, Yun Chen once again purified the spirit grass.

She was very careful with every movement, and finally finished refining another spirit grass. After observing the purity, Yun Chen was overjoyed, although the purity was still not high enough, it was much better than before.

In this way, she continued to practice purification, and after wasting dozens of spirit grasses, she finally purified one with a purity of about ninety-five percent.
