In fact, Tong Chen already has experience in alchemy, all along, the old man Qian for the Tong family to refine is a kind of pill called "Huang Lingdan", the pill has the effect of accumulating condensation, warming the meridians and nourishing the pulse, in the eyes of ordinary people, this is already an excellent elixir, but compared to the Qingxin Pill refined by Tong Chen, the medicinal effect of Huang Lingdan is much worse.

Although both of them belong to low-level pills, they are only suitable for low-level cultivators, but the medicinal materials used to refine these two pills are 108,000 miles apart, as far as Tong Chen knows, refining Huang Lingdan only needs less than ten kinds of medicinal materials, but refining Qingxin Dan requires more than 30 kinds of medicinal materials, and there are no less than four or five kinds of precious medicinal materials, both are low-level pills, Qingxin Dan belongs to the low-level of the high-level, and Huang Lingdan is only an extremely common pill among low-level pills, and it cannot be compared with Qingxin Dan at all.

Therefore, for Tong Chen, who has refined the Qingxin Pill, refining the Huang Lingdan is really not difficult at all, if he wants to refine it in two days, he can refine one furnace, if it weren't for the insufficient temperature of the fire specially used for alchemy in the medicine garden, he can refine several furnaces a day, but in order not to make Zhao Lan suspicious, he can't start alchemy immediately, at least two trips outside, so that Zhao Lan feels that he can only start alchemy after going to his "master" for advice.

That night, Tong Chen transplanted the phantom spirit grass he brought back from the mountain into his world, and after that, his divine sense continued to explore in that world, aimlessly, in fact, he has often done this in the past few months, although that world belongs to him, but that world is too big, so big that even if he often goes in to explore, he can only barely detect a corner of that world.

Just when Tong Chen's divine consciousness was wandering aimlessly in that world, suddenly, he noticed that there was an extremely faint purple light in the distance that kept flashing, his heart moved, and his divine consciousness immediately locked on the purple light, and in an instant, he came to the purple light, and when the divine sense swept down, Tong Chen found that there seemed to be a big tripod standing on the ground below, and the purple light he saw from a distance just now was emitted from the big ding.

Curious, Tong Chen slowly approached the big ding, and after standing in front of the big ding, he found that this big ding was really shabby, and the black protrusion of the whole body was not to mention, and the texture carved on the stomach was blurry and couldn't see the original face.

Tong Chen was wondering how such a black and dull Dading could glow purple, when suddenly, he noticed that there was a light emitting from the lid of the Dading.

He jumped on top of the big ding, took a lot of effort to open the lid of the ding, and found that there was a wisp of purple fire in the empty ding, the flame was very weak, and it looked as if it would be extinguished at any time, Tong Chen was surprised by this, and suddenly found that the flame flew up from the ding and then rushed directly towards him, and before he could react to what was going on, he felt that the whole body was "soaring" The ground suddenly burned like a fire, and for a moment his mind went blank, and he only felt as if he had fallen into an endless sea of fire, and he tried his best to struggle in this sea of fire, but he fell deeper and deeper...... Sink deeper and deeper......

I don't know how long it has been, when Tong Chen's consciousness awakened again, there was a faint purple light flowing up and down in his eyes, he stretched out a finger and lightly touched the void in front of him, and in the next second, a wisp of purple flame burst out of his fingertips, and then jumped back and forth on his fingertips, looking very demonic!

At the same time, the words "Ziyang True Fire" suddenly appeared in Tong Chen's mind, according to the introduction of Ziyang True Fire in the inheritance obtained by Tong Chen, Ziyang True Fire is an extremely strong high-grade fire, characterized by never giving up until the last moment, and it is an excellent fire for alchemy refiners.

It stands to reason that this kind of fire should not appear in the mortal world, let alone in front of Tong Chen, a small monk in the spiritual period, but because of this wonderful world of unknown origin, Tong Chen saw the big ding, and then saw the remaining trace of the flame of the purple yang true fire in the ding, and under the mistake, he also absorbed the fire, and now this rare fire has been completely mastered by him.

After digesting the information about the Ziyang True Fire, Tong Chenzheng felt a little incredible, and immediately after, an image of a purple tripod appeared in his mind, as well as detailed information about this purple tripod.

This purple tripod is called Ziyang Baoding, yes, it is also "Ziyang", and the first two words of Ziyang True Fire are exactly the same, to say that this Ziyang Baoding, that is really the treasure of the fairy family, is made of a strange stone that absorbs the essence of heaven and earth, once the master is recognized, it can be used as an offensive and defensive treasure according to the master's ideas, and it is an excellent treasure for alchemy and refining.

Reciting the four words Ziyang Baoding silently in his heart, his eyes swept over the black tripod beside him, and Tong Chen was almost about to jump up in shock: "Isn't it? Could it be that the broken tripod next to me is the Ziyang Baoding? This is too bad, right?"

No wonder Tong Chen couldn't believe it, the Ziyang Baoding that appeared in his mind was full of brilliance, and it was not a mortal thing at first glance, but what about the big tripod next to him? Although the size and appearance of the Baoding in his mind were quite consistent, but this Dading was black and shiny all over his body, not to mention that the whole body still exuded a kind of rotten atmosphere, if it wasn't for careful confirmation and comparison, Tong Chen would not dare to associate the broken tripod in front of him with the Ziyang Baoding in his mind.

With the mentality of trying, Tong Chen bit his finger and dripped a drop of blood belonging to him onto Da Ding's body, originally he thought that this Da Ding was damaged like this, and he should not have any reaction to his blood, but he didn't expect his blood to fall on Da Ding, Da Ding

The body of the tripod immediately became brighter, although it was not as brilliant as the purple yang treasure tripod in his mind, but compared to the black tripod before, I don't know how many times more beautiful.

Tong Chen stretched out his hand to touch Da Ding's body, but the next second, Da Ding suddenly disappeared in front of his eyes, seeing this, Tong Chen's heart was tight at first, and then his mind moved slightly, and his divine consciousness withdrew from this world, and came to the Dan Sea, and sure enough, he found that there was a small Ding floating in the Dan Sea, which was the appearance of Ziyang Baoding after it became smaller.

"Could this be regarded as a success in recognizing the Lord by dripping blood?" Tong Chen muttered in his heart, and stared at the Ziyang Baoding for a long time, and then his consciousness withdrew from the Danhai.
