Lin Han didn't bother to care about the many black stains that had been forced out of his body, he wanted to try where the limit of his promotion was.

After hollowing out all the green ores, Lin Han found that his body had also reached the limit, and his cultivation had also been raised to the level of the third order of the spirit immortals, although the green spirit stones were not comparable to the number of purple spirit stones, they were already quite a lot. It was only after all of them were used up that they were promoted to the third order of the Spirit Immortal, although it made Lin Han a little painful, but thinking that some people couldn't break through for thousands of years, he was already very lucky.

And to be able to improve so much in a short period of time is already a miracle.

Cross-legged pranayama, Lin Han planned to digest the spiritual power he had absorbed first, and then try to refine some Xuan Immortal grade pills. After all, time stands still in this space, and he has time to refine. And the promotion of the rank will not bring thunder tribulation, and when you come out of this space, there will be a thunder tribulation.

After searching in his mind, Lin Han found a pill recipe, and the origin of this pill recipe was naturally obtained from the desert palace of Boya.

Thinking of Boya, Lin Han's face was a little solemn, he hoped that Boya could always be so pure and innocent, at least in this way, she would be happy. If you remember the past, I'm afraid you will have to go on the road of blackening every minute.

He must try to be strong, strong enough to protect anyone around him.

Looking for the medicinal materials on the pill from the ring that Qing Shengzi gave him to store the medicinal materials, Lin Han found that they could all be found, and after picking out these medicinal materials, he began to refine the pills.

It is indeed very difficult for the Spirit Immortal Rank to refine the Xuan Immortal Rank Pill, but it is still within the range that Lin Han can bear, and there is still an Immortal Rank Pill that can improve his spiritual power on the side. Lin Han's entire refining process was basically spent refining while taking drugs.

Lin Han couldn't figure out how long he had been in this space, he should have spent several months cultivating by himself, and now he was refining again, and it would take a long time to come out.

It's just a pity that although the first pill was made, because the grade was too low, it was directly broken into slag. His first attempt failed. Gritting his teeth, he began to try a second time.

The elixir he refined was considered mid-level among the Xuan Immortal Rank products, neither high nor low. Because medicinal materials are relatively common, there are a lot of medicinal materials given to him by Qing Shengzi, so Lin Han plans to refine this elixir.

Wiping his nose, Lin Han continued to refine with perseverance.

This time, he was more engrossed in alchemy and devoted himself to alchemy.

Even Shennong came out and sat on his shoulder, he didn't know.

Shennong was naturally attracted by the medicinal fragrance, the fragrance of medicinal herbs is an extremely tempting existence for every Dan Ling, Shennong jumped down from Lin Han's body, and began to help Lin Han clean up the residue on the side, casually picking up the broken pill residue and eating it.

Although it is a failure, at least the above medicinal effect still has a little effect.

When Lin Han finished refining the pill, he was pleasantly surprised to find that he had become a pill, although it was a little lower than he expected, but it was already much better than the first time he fried the pill. Looking at the Xuan-level Xuanxian elixir in his hand, Lin Han looked relieved.

Suddenly, there was a sound of rustling in my ears, and when I looked down, I found that Shennong was picking up medicine residues to eat.

The corners of Lin Han's mouth twitched, feeling that he couldn't bear to look at him directly.

"Tell me if you want to eat! Why eat all these scraps? Lin Han asked puzzled.

"The residue is also a medicinal herb, don't waste it, and the effect is good! What kind of elixir are you refining? Shennong found that after eating these medicinal residues, his whole body became significantly lighter, as if he had returned to the feeling of his youth.

When he raised his hand, he found that the skin on his hand had become smooth and firm, and he was surprised to raise his hand and touch his cheek, and found that his cheeks had also regained his youthfulness and his long beard was gone.

"The effect of this rejuvenation pill is good!" Lin Han examined the changes in Shennong's appearance, and finally simply stuffed the Rejuvenation Pill that he had just refined in his hand into Shennong's mouth.

"What are you doing?" A pill of this size was stuffed in his mouth, and Shennong's entire cheeks bulged. "Help me try the medicine!" Lin Han said with a smile.

"Oh......" Shennong puffed out his mouth, and after saying a word, the elixir in his mouth gradually melted.

When he reacted, he found that his body was a little smaller again, and he looked up at Lin Han in front of him in shock, and he seemed a little at a loss.

"I'll go! How to become a baby! "Shennong is drunk, the medicinal properties of this rejuvenation pill are also terrible, he became a young man after eating some medicine residue, and after eating a whole pill, he directly became a baby.

"It seems that my result is successful, and I will practice a few more times to be perfect." Lin Han nodded with satisfaction, gently picked up Shennong, and put it on his shoulder.

Shennong was speechless, only blaming himself for being greedy and being used as a test specimen by Lin Han.

He is the spirit of the Ten Thousand Saints Pill! How can you go out to meet people when you become this milk doll!

Next, Lin Han was familiar with the refining method of the Rejuvenation Pill, and he also successfully refined the Rejuvenation Pill of the Yellow Order. After putting away this elixir, Lin Han felt a sad gaze looking at him, turned his head to look, and found that it was Shennong.

He suddenly thought of an elixir that was the opposite of the Rejuvenation Pill and could make people grow quickly.

Thinking of this, he began to look for medicinal materials for alchemy again, in short, Lin Han was completely immersed in the world of alchemy, and he didn't know how long it had been. He sent the refined elixir to Shennong's mouth.

Shennong was a little afraid, for fear that Lin Han would feed himself some strange pills.

However, succumbing to Lin Han's slightly threatening eyes, he swallowed with tears.

The moment he swallowed it, he found that his body was growing rapidly, until he became an ordinary young man, and then stopped growing.

"My old fellow is rejuvenated!" Shennong opened his mouth happily, and Lin Han's growth made him very pleased.

"Well, sort of!" Lin Han nodded, estimating that the time was about the same. And after such a long time, he felt like he was about to collapse.

After putting Shennong back into his own space, Lin Han left this space.

As soon as he went out, he saw Qing Shengzi guarding his room, and after seeing himself come out, he greeted him, "How is it?" What level of elixir can you refine now? "Actually, Qing Shengzi didn't have much hope, but Lin Han was always able to create miracles, so he also had some small expectations in his heart.
