A few days later, Tang Chen's batch of Seven-Star Spirit Grass had fully matured, and the preparations related to alchemy had already been made.

Auxiliary elixirs and ores, Tang Chen found a batch, and in order to prepare for this alchemy, Tang Chen also deliberately went to a deep mountain in the Jianghai region.

Because although the elixir can be bought in the medicinal material market, it may not be possible to find a very satisfactory one. As for the ore, it is even more difficult to find, and you have to go deep into the mountains to find it.

There is also the water used in alchemy, the tap water for industrial processing is obviously not good, and the natural river water is also okay, but ......, to be honest, Tang Chen has not seen a clean and clear river in Jianghai for so long.

The water of alchemy still has to be the mountain spring in the deep mountains.

In the past few days, Tang Chen has been busy with these things.

There is also a small alchemy room in this courtyard of Dr. Mo, and even the alchemy objects are there, but the alchemy furnace Tang Chen is not satisfied, so he goes to change it again.

It's not the first time to refine pills here, Tang Chen has helped Leng Haishan refine two Guyuan Pills before.

Tang Chen still spent three hours refining two Gu Yuan Dan pills today, which were intended for Su Ya to take.

The cold spirit in Su Ya's body was expelled, but because the aura in her body was absorbed, her body was now weak, and she needed to recover her vitality.

Gu Yuan Dan, this basic physiotherapy pill is relatively easy to refine, Tang Chen is now rich in elixir resources, and the efficiency is even higher than last time, Tang Chen also added a fruit of the Seven Star Spirit Grass to it, which greatly increased the effectiveness of the refined Gu Yuan Dan.

"This is my precious spirit grass, it's really cheap for you girl!" Tang Chen took the two Gu Yuan Pills that had been successfully refined, smiled playfully and said to himself, and then, he put these two Gu Yuan Pills into a small blue and white porcelain vase.

Today's refining process of this Guyuan Pill can be regarded as a warm-up, warming up for Tang Chen's further refining of the Qi Refining Pill.

Tang Chen fused the treated spiritual grass and the mountain spring together, started the furnace fire, and then used saltpeter, tin and other ores to assist the furnace fire.

The use of spirit grass is very particular, this seven-star spirit grass can really be used for alchemy, in fact, there are only flowers and fruits, as for those rhizomes and leaves, although they also contain the ingredients required for the elixir, they are already very low, so simply remove them, so as not to affect the ingredients of the elixir and increase the unnecessary alchemy time.

Ore is also a must, these ores found by Tang Chen are very ordinary, if you can find such a good thing as a spirit stone, then the alchemy efficiency can be said to have greatly increased.

The same is true of this mountain spring, if you can find the spiritual spring, it will also greatly shorten the time for alchemy.

Therefore, this alchemy is a cumbersome systematic process, and the quality of the time to become a pill is closely related to many factors.

However, whether it was Spirit Grass, Spirit Stone, or Spirit Spring, these things were extremely rare resources, whether it was Spirit Grass, Spirit Stone, or Spirit ......Spring. Tang Chen wandered in the mountains for a few days this time, and he didn't find a single spiritual object that could surprise him a little.

There is no way, resources are hard to find, and for the time being, we can only settle for a while.

Tang Chen knew that he was now refining the Qi Refining Pill, the first element of the spirit grass, the spirit stone, the spirit medicine, the spirit spring and so on were all auxiliary elements.

If these things are in poor condition, then the time to refine the Qi Refining Pill is seventy-seven and forty-nine days. Of course, the premise is that these things are very poor, and the refiner is also a beginner cultivator.

Although Tang Chen's things were of average quality, they were not very bad, and he was also a cultivator in the middle stage of Qi refining.

Taken together, this refining time can still be shortened, especially Tang Chen, who now has enough True Qi in his body, and can use True Qi to stimulate the fire and further reduce the refining time.

Tang Chen immediately activated the true qi, and the furnace fire quickly rose, and the golden furnace fire was immediately wrapped with a faint red halo, which was a flame urged by the true qi, which already had a certain spirituality.

At that moment, Tang Chen closed his eyes and devoted himself to the process of alchemy, refining for another three hours.

Compared to the three hours of refining Gu Yuan Dan before, these three hours were much more tiring. If the first three hours were a walk, those three hours would be a triathlon.

At the end of the three hours, Tang Chen was sweating profusely, as if he had just come out of the sauna.

It's still early for Dancheng, but he can't bear it, this kind of true qi depletion is too great, and he can't completely exhaust all his true qi because of alchemy, he always has to keep some.

"Alas! Spirit grass, elixir, spirit stone, spirit spring, ......, these mainly determine the quality of the elixir, not the key factor that determines the refining speed, what really determines the alchemy speed is the heat! Tang Chen muttered to himself.

In fact, he thought about it before, does his stone bead have an auxiliary effect on alchemy? He also tried, but did not find any effect on alchemy.

"If you can take the spiritual fire of heaven and earth, then the speed of alchemy is bound to increase greatly, with the spiritual fire of heaven and earth, what is just a qi refining pill, Zhuji Dan, Yuanying Dan, and Huashen Pill, all of them are fine." Tang Chen's eyes were revealed.

Heaven and earth spiritual fire, that is even more unattainable!

Tang Chen had heard this thing from the mouths of those elders in the Immortal Gate, and he had not seen it with his own eyes.

The Qi Refining Pill was not refined, but with the assistance of True Qi, the time was greatly shortened. Tang Chen knew that as long as there was enough spiritual energy to replenish his body, this Qi Refining Pill would soon be refined.

With that stone bead to assist him in absorbing spiritual energy, he believed that refining the qi refining pill would be very fast, he estimated that if he could replenish enough spiritual energy, he could become a pill in seven days.

Tang Chen did the aftermath, and then took out the half-refined Dan liquid, took its essence, and removed its dross. Then, this alchemy caused the true qi to be seriously depleted, and he then used the stone bead to assist in absorbing some spiritual qi as a supplement for the true qi in his body.

By the time he finished work, it was already evening, and there was a sudden movement in the yard, and when he went out, he saw that there was actually a dog in the yard, eating the dross that he had thrown away from alchemy.

I go, does this dog also want to become an immortal?

Tang Chen smiled secretly, although this is the dross of alchemy, it is also a very good spiritual thing, many times better than the most nutritious food in the world, although the taste is not good.

The dog also had a big appetite and ate all those things.

The courtyard door was closed, Tang Chen didn't know where the dog came in, and the dog looked quite familiar, and he was also very warm to Tang Chen, as if he was the owner.

Tang Chen suddenly remembered that this dog was the Rottweiler raised by the Su family. When Tang Chen arrived at Su's house on the first day, there was a Kuo Shao with a "master" who used spiritual magic on it, trying to make it attack Tang Chen, but he was controlled by Tang Chen and bit the man's buttocks.

"Haha! Long time no see, friend! Tang Chen stroked the dog's head.

This dog was originally leashed in the Su family, but today it broke free from the chain and ran out, this is not surprising, this dog has already recognized the owner last time after being controlled by Tang Chen's input of true qi, just like Shen Mange's puppy, he saw Tang Chen very closely.

It seems that this Rottweiler escaped from the Su family and came to join Tang Chen.

"Well, you'll live here from now on." Tang Chen said.

Anyway, he is alone in this courtyard, and sometimes he is quite boring except for cultivation, so he treats him as a companion. Of course, the most important thing is that Tang Chen knows that this dog can't be beaten away after recognizing the master, unless it is killed.

…………

Tang Chen then took a shower, changed his clothes and went back to Su's house, and sent Gu Yuandan over for Su Ya to take it.

"After taking another Guyuan Pill in a week, Miss Su's illness will be completely cured, and I should almost leave." Tang Chen said to Su Yan.

"Let's go?" Su Yan was stunned for a moment, is this guy going to resign?

"Can you stay? The matter of salary can be discussed again. Su Yan said, this is the meaning of retention.

"This ......"

Tang Chen smiled: Does he still care about this bodyguard job with a monthly salary of tens of thousands now?

Although he could have come up with the momentum of "is there a difference between labor and management", he didn't. Speaking from the bottom of his heart, Miss Su was still good to him, helping him and trusting him when he needed it most.

If it weren't for a series of experiences in the Su family, he wouldn't have discovered the secret of that stone bead by now, and he wouldn't have achieved his current achievements.

"Sister, this guy is leaving, is it possible that you are still reluctant to give him up?" Su Ya exaggerated.

In fact, how to say it, Su Ya doesn't want this kid to leave now, although he hates it a little. However, Miss Su Er has always been unforgiving.

"I'm not sure about Su Ya's condition, you can stay a little longer." Su Yan found a reasonable reason.

"Alright! The two eldest ladies of the Su family jointly retained you, so you said that you would not give this face, right? Su Ya said with a strong face.

“……”

Tang Chen was speechless, are you retaining?

"We're going to have a drinking party tomorrow, shall we?" Su Yan said to Tang Chen.
