The immortals of the two worlds started from farming and refining pills.

Li Qing raised his eyebrows, turned the alchemy furnace back into Nirvana Fire, put it back into Dantian, and then picked up the foundation-building pill that was glowing purple.

This foundation-building pill is round and golden, with a light purple line on it.

Originally, after most elixirs are made, if they are not sealed immediately, their medicinal properties will dissipate little by little until they become useless.

However, this foundation-building pill is different. It is flawless and natural, and the medicinal properties are firmly locked inside the pill. It looks extraordinary.

"Could this be the legendary top-grade foundation-building pill?" Li Qing was slightly shocked.

However, this item was mostly circulated among Nascent Soul forces. Li Qing himself had never seen the real thing, and it was not mentioned in the two foundation-building pill recipes, which made him a little uncertain.

He hesitated for a while, sealed the foundation-building pill in a jade bottle, and put it in the pile to be handed over to Tanyuan Immortal City.

So far, Li Qing opened the furnace continuously and refined three rounds of foundation-building pills, producing a total of five genuine pills, one inferior pill, and one suspected to be of the best quality.

If a second-level alchemist like Liu He knew about this, his defense would probably be broken immediately.

He only kept one genuine pill for himself, then came out of seclusion, taking the other six foundation-building pills with him to find Master Cao.

Unexpectedly, Master Qingli had not left yet. He was in the spiritual field, observing the lotus flowers that were imbued with the mysterious yellow aura together with Master Cao.

"Fellow Daoist, have you come out of retreat?" The two Immortals looked over with a smile.

Li Qing smiled and nodded: "Hello, two Taoist brothers! I wonder if this lotus is pleasing to your eyes?"

True Man Qingli said with a smile: "Daoyou have indeed made great achievements in cultivating spiritual plants. After the blue lotus seed was transformed, it actually contained a mysterious yellow energy."

"Taking it after it matures can also have a good stabilizing effect on Jindan Zhenren's breakthrough to a small realm. It is also considered good among the third-level spiritual plants."

Master Cao also said: "I see that this lotus and your Kunpeng blessed land seem to be connected by destiny. In the future, when the blessed land is further developed, this Xuanhuang Qinglian will have the opportunity to transform."

Li Qing said modestly: "It will be very difficult for Fudi to advance further. I dare not dream that far. For the time being, I will be happy to manage this little piece of land well."

Qingli and Master Cao smiled but said nothing.

Suddenly, the sound of children playing in the distance caught Li Qing's attention.

He looked up and saw two Taoist children sitting under Master Qingli, laughing and playing with two half-demon children, Yuanbao and Chili.

Both are half-demons. Yuanbao and Yuanbao have now grown into young boys. They behave like ordinary people and have reached the middle stage of Qi training.

On the contrary, the two disciples of Qingli were a few years older, but they still looked like naughty boys, their behavior was childish, and their cultivation was almost non-existent.

Noticing Li Qing's gaze, the two Taoist children pulled their eyelids, made faces at them, and then burst into laughter.

Seeing this, Chili hurriedly bowed to Li Qing, and then gently advised: "This is a bit rude!"

The two naughty boys shook their heads and it was unclear whether they heard anything or not.

Taoist Qingli shook his head and explained to Li Qing: "These two children are born with a defective spirit and soul. Their intelligence has remained at the level of three or four years old. Therefore, they act eccentrically. I hope you can forgive me."

Li Qing sighed: "What crime did the child commit? How could I really tell them? But, is there no room for treatment for them in this state?"

True Man Qingli was helpless: "Even if True Lord Yuanying takes action, it will cost a lot."

"What's more, you should have guessed that it was not easy to save the lives of these two children in that case, let alone save them."

Master Cao at the side said with a smile: "Brother Daoist has great magical powers, I think he is not far from the Nascent Soul stage. When you succeed, cure these two kids, and no one else will have any objections." Master Qingli smiled and said: "Thank you for your good words, Brother Daoist."

He turned and looked at Li Qing: "I have finished everything on this trip. Now that you are coming out of retreat, it is a good opportunity for me to say goodbye to you."

"But these two boys are quite restrained in my Yanling Valley. When they come to your place, they can release their nature. I wonder if you are willing to let them stay here as guests for a few days?"

Li Qing was actually not very willing to do so, after all, there were many secrets in Qinghe Valley.

This time, in order to avoid revealing their true identity during the banquet, Asun and the others were specially sent to the elf world.

If we leave these two children in the blessed land, we will have to be careful when the elves appear, which is not very convenient.

Unexpectedly, Master Qingli continued, "These two naughty boys have special bloodlines. They are often accompanied by lotus-like spiritual plants, which can also promote their transformation. Perhaps they can be of some use to you in cultivating the Xuanhuang Qinglian."

Li Qing's words of refusal came to his lips, but he swallowed them back: "Sir, that's not right. I also feel deeply sorry for what they have gone through. Don't worry, I will definitely not let them down."

Qingli Zhenren laughed: "In that case, thank you very much, Fellow Daoist Li. You two stay for a while, I will leave now."

Having said that, he asked someone to bring his dragon beast Chenxiang over, and then he drove away in a carriage.

After he walked away, Cao Zhen said with envy: "Brother, when you leave, the next time you hear news, it will be when you break through to the Nascent Soul stage."

Li Qing was stunned: "Break through the Nascent Soul..."

Master Cao turned his head and looked at the two naughty boys: "Haha, it seems that I bet on the right treasure by having Tanyuan Immortal City here with you, Taoist friend."

"This one has the magical power of time and is quite talented in divination. He left these two with you, in fact, he is entrusting them with his care. From this point of view, your future is limitless."

Li Qing's mind was churning, but he never showed it on his face: "Brother Cao, you are too polite. Maybe Master Qingli really wants them to stay here and play for a while longer."

Master Cao just smiled and said nothing.

Li Qing did not dwell on this too much, and transmitted his spiritual consciousness: "In the past half month, I have tried to refine three furnaces of foundation-building pills, and the harvest was quite fruitful."

"Brother, please follow me to the cave and taste the foundation-building pill I made to see how it is different from that of fellow Taoist Liu He and fellow alchemists in the Immortal City."

Master Cao was slightly shocked: "Daoyou is really swift and decisive. I really thought you were in seclusion to meditate and discuss the Dao."

The two of them walked and talked, entered the palace, temple and cave, and then set up many restrictions.

When Li Qing took out the inferior foundation-building pill, Master Cao remained calm.

When Li Qing took out four foundation-building pills, Master Cao raised his eyebrows.

But when the foundation-building pill with purple patterns appeared in front of him, Master Cao stood up suddenly, with a look of horror on his face: "Top-grade foundation-building pill?! How is this possible!"

Li Qing thought to himself: "It is indeed a top-grade foundation-building pill."

He asked calmly, "Brother Dao, why are you so surprised? Is there anything about this top-grade foundation-building pill that I don't know?"

Only then did Master Cao realize that he had lost his composure, and he calmed himself down and said, "Daoyou, this really gave me a big surprise."

He sat down slowly, pointed at the purple-patterned foundation-building pill and said, "Daoyou, you should know that taking pills to build your foundation is a tricky thing to do."

"Although there will be no elixir poison left after the breakthrough, and there are no hidden dangers. But compared to building a foundation on your own, the true essence is a little less sharp." (End of this chapter)
