Zheng Xiaotian has only one son, or the kind of son who has a great future for development, if it weren't for him to go to the front line to mix military merits, he would be reluctant to let his son go, what he didn't expect was that after his son arrived at the front line, he originally belonged to the alchemy department and was in the rear, but he was attacked by the enemy, and the entire alchemy department was served in one pot, and his son was directly destroyed after becoming a prisoner.

Zheng Xiaotian is still a character here, but in the whole country, he is not enough to see, and he wants to get a Haidan for his son, but he can't do it at all, and if he thinks about it, he can only refine it himself.

As a third-order Dan Master, Zheng Xiaotian still has self-confidence, as long as he has the materials, he believes that he can completely refine this elixir.

It took some time, Zheng Xiaotian still found all the spirit grasses, even the rarest thousand-year-old spirit grass was found here in the Dantang.

Overjoyed, Zheng Xiaotian planned to go to this Dantang, which had thousands of years of spiritual grass, to refine it.

Dantang is naturally the most suitable place for alchemy, and it is also convenient for all aspects of things.

In order to ensure that this spirit grass could be successfully refined, Zheng Xiaotian even invited some Dan Dao masters to help.

Sitting in the Dan Hall, looking at the people who were preparing, Zheng Xiaotian adjusted his breath, although he was confident, after all, he also rarely carried out the refining of this kind of sea replenishment, and the lack of spirit grass was a key.

"Keep them away from some. Glancing at the people who brought them to study, Zheng Xiaotian said in a deep voice.

When several elders waved their hands, Su Ningyu and the others all took a few steps back.

It doesn't matter if Suning Yu arrives, as long as he can observe it closely, with his eyesight, don't talk about this distance now, even if it is farther, it can be seen at a glance.

The elders were all inspecting the situation of the spirit grass one by one, and Su Ningyu started with the most ordinary spirit grass, and each one looked at it seriously.

After a while, Su Ningyu knew the medicinal properties of each spirit grass, and then looked at those spirit grasses with high prices.

Now Su Ningyu already had a database of pharmacists contained in various spirit grasses that he had made out by himself, and there were records of the medicinal properties of each spirit grass in some key years, which was his biggest achievement during this time.

Anyway, Suning Yu's brain space is getting bigger and bigger now, and he got some of the computer's programming methods here to design, so the entire database is very detailed in the data record, and it can be extracted as soon as possible when it needs any kind of data.

When doing this, Su Ningyu still has some understanding, in fact, his brain is completely a computer, and he can study this aspect in the next step, and it is estimated that he will be able to do something special.

After recording the medicinal properties data of these spirit herbs of Haidan, the next thing Suning Yu had to look at was the process of their refining.

"Let's start!" After Zheng Xiaotian said a word, the Dan Fire was activated, and the entire alchemy had already begun.

Zheng Xiaotian is a veteran of alchemy, and there is no problem with his technique at all, and Su Ningyu has even learned a lot from it.

Although he couldn't see the situation inside the Dan Furnace, Su Ning Yu's powerful divine sense was able to penetrate into the Dan Furnace, and he could clearly see the fusion of various spiritual grasses in the entire Dan Furnace, and these things would be used for deduction in the next step, which was a rare data.

It's time to merge into the thousand-year-old spirit grass!

When he saw Zheng Xiaotian pick up the spirit grass, Su Ningyu also looked at it seriously.

Just after the spirit grass was put into the Dan furnace, Su Ningyu found that the entire Dan furnace had undergone a great change in an instant, and the entire Dan furnace was boiling.

All kinds of medicinal power were fused in the Dan furnace, and Zheng Xiaotian's technique was also faster.

I don't know what the situation is, Su Ningyu found that there was a problem with one of Zheng Xiaotian's tricks, not only did he not speed up the process of this fusion, but after he played the trick, the medicinal fusion process in the entire Dan furnace became chaotic.

Not good!

With Su Ningyu's alchemy experience, as soon as he saw this situation, he knew that it was bad, and it was estimated that this furnace of elixir would be bad.

Su Ningyu quickly thought about ways to improve.

At this time, Zheng Xiaotian's face also changed greatly, and he used a faster speed to play all kinds of complicated tricks, trying to stabilize the situation.

Those Dan Masters also changed their faces slightly at this time, and they all played various tricks, trying to help adjust this chaotic situation.

However, even if they used such complicated methods to save the day, they ultimately failed.

First an elder stopped and sighed lightly, and then, one by one, the elders stopped, they knew that this furnace pill was ruined.

Zheng Xiaotian became furious at this time, and did not stop, but kept making tricks.

The son's hope is here, but it's a pity that he actually wasted this furnace of Dan refining.

Zheng Xiaotian knew that this was his own reason, because in the end, he was busy looking for the matter of Lingcao, and under the lack of mental strength, there was a problem with the trick he played, and he now regretted it extremely much.

After a while, Zheng Xiaotian looked at the Dan furnace in a daze, and when he reached out to open the lid, what everyone saw was that a waste pill was there, and it was not as clear as it was after becoming a pill.

Alas!

The elders all sighed softly.

Zheng Xiaotian was almost about to cry, so a furnace of pills was defeated in his hands, he had known that there would be such a situation, he should have taken a pill of Tuoshen Pill in advance, and now it was too late!

The people watching sighed secretly at this time, and no one expected such a situation.

"This Dan can still be saved!" Just as everyone sighed secretly, a voice came.

What the?

The sound was like thunder, shaking everyone hard, and all eyes were on the person who spoke.

As far as the eye can see, everyone sees a young man standing there quietly.

"What are you talking about, young man, don't talk nonsense!" said an elder.

Under the current circumstances, there are people who dare to say that there is still salvation.

Everyone's eyes fell on the pill again, but they shook their heads again, how can such a waste pill be saved, isn't it a joke?

"Who brought this in, play the piano indiscriminately!" another elder said in a deep voice.

"What are you talking about, and there is still salvation?" Zheng Xiaotian completely disregarded his image, rushed over and grabbed Su Ningyu's hand.

Yes, this is what Su Ningyu said, after studying the entire alchemy process, he knew that this pill lacked some medicinal properties, as long as it was integrated, it would definitely be able to be saved.
