After the most difficult time, gradually, Yang Kai felt that his abdomen was no longer so swelling, and the power of pure yang was condensed by himself. The most significant change was that the gold color on the Taoist seal increased a lot.

He took out the Yuanyang Chronic Acid from the Tianyin Jade Box again and took a few bites.

The golden pure yang power in his body exploded again, squeezing his internal organs, filling his body with flesh and blood, and even causing him to emit a faint golden light.

The power of the Taoist seal is activated again, causing the pure yang to pour into it.

For a long time, Yang Kai was repeating this process.

I don’t know how long it took, but the pure yang power in the seal gradually became full, and the Yuanyang Xuanguan that he spent 200 million to exchange for was basically consumed by him.

When the last bit of Yuanyang Scarborist's medicinal effect was dissolved in the abdomen and the power of pure yang poured into the Taoist seal, Yang Kai suddenly felt that he had some unusual changes.

I realized in my mind that my own yang movement has been completed, and now there are only two steps left before the Kaitian Realm!

And now he has reached the point of opening the sky halfway.

Generally speaking, as long as a warrior can condense five kinds of power, it can be called the half-step opening of the sky. This is not a realm, but it can exert more powerful power than the Idle Emperor.

Half-step opening of the sky is of great significance to other warriors, because after practicing to this level, they can look forward to the real opening of the sky and their own strength can also be improved leaps and bounds.

But for Yang Kai, it was useless.

Because even if he only condensed four kinds of power, he could already compare with the lower grade Kaitianyi. Although he has refined the seventh grade Yangxing, he needs three uses of one mind to activate the heart sutra of the reverse Yin and Yang Five Elements to maintain the stability of the Taoist seal, and his own strength has not increased much.

This is just one mind and three uses. If you look back, you will need to use one mind and four uses, and the impact will be greater.

The best way is to first condense the gold movement, so that he can correct the situation and no longer has to worry about maintaining the operation of the Xuanyu Heart Sutra against Yin and Yang and Five Elements.

But the best resources are hard to find. Who knows if you will get a gold or a Yinxing next time?

After calming down, checking himself, and confirming that there were no hidden dangers, Yang Kai breathed a sigh of relief and calculated the time. It took him almost two months to refine Yuanyang Xuanguan this time.

This time is definitely not long. If it were other warriors, even if they succeeded in the end, it would most likely take a year and a half, or even three or five years.

After all, condensing the power of Yin and Yang and Five Elements has a huge burden on one's own Taoist seal. If you act too quickly, it is very likely to cause unnecessary trouble.

Which warrior is not careful when refining the power of Yin and Yang and Five Elements, for fear that the Taoist seal will not be able to withstand external pressure.

Only Yang Kai has a strong foundation and has taken more than a dozen drops of Taoist Divine Water to strengthen the Taoist Seal to the limit, so that he can ignore this influence.

Waves to remove the ban in the secret room, and soon the door was opened. Yuehe and the boss lady came in together. The two of them should have been waiting outside, otherwise it would be impossible for them to come in so soon.

When he came to him, the boss lady looked at him and said, "Is it done?"

Yang Kai nodded slightly.

The boss lady was a little surprised: "It's quite fast."

Yuehe is not surprised. When Yang Kai condensed earth in Taixu realm, it seemed that it took almost so long.

"Where are the things I want?" Yang Kai looked at Yuehe.

"It's all here." Yue He immediately handed out a space ring.

Yang Kai nodded and took it, and his spiritual thoughts swept into it to investigate.

At the same time, the boss's wife tapped his forehead with one hand, and the strength around her body surged silently to investigate the situation in his Taoist seal.

After a while, it was confirmed that Yang Kai was really not a problem, so he took his hand back and looked at him with a serious look: "Boy, the road you are walking is very dangerous and is very likely to cause a disaster for one's own life. Even if there is no disaster for one's own life, it will be very obstacles. You have to think clearly."

Yang Kai smiled and said, "Boss, you have said this a lot. Since I have this unique advantage, if I don't try it, I will definitely regret it in the future. As for obstacles and dangers... I will just block the water and soil!"

He initially refined the essence of the immortal tree without knowing it, and had a very high starting point. Later, he obtained the Golden Crow True Fire, and then obtained the dragon ball of the earth-type dragon...

With such a powerful foundation and advantages, how could Yang Kai not work hard to advance to the top-grade Kaitian? People go to high places and water flows to low places, which is the eternal truth.

The boss's wife's head and nodded, and she didn't say more.

Yang Kai asked again: "When will the Blood Demon Cave Heaven be opened?"

The boss lady closed her sleeves and said, "I have been paying close attention to you. There is no movement yet. I am afraid I will have to wait for a few more months."

"Then I'll ask the boss to continue to pay attention. I'm going to retreat. If there is any news on the Blood Demon Cave, I'll notify me as soon as possible."

"Don't worry, you won't miss this opportunity." The boss's wife angrily glanced at him, knowing that he had something to do, so she gave a few words of advice and took Yuehe out.

In the secret room, Yang Kai re-opened the ban, rested for two days, and recovered his tired spirit.

Two days later, Yang Kai sacrificed a alchemy furnace and took out the space ring that Yuehe had given him before, as well as the elixir recipe for the Tianyuan Zhengyin Pill that he obtained from Danxia Auction House.

He wants to refine the Tianyuan Zheng Seal Pill!

This thing is priceless. Ye Jian and King Teng had previously pleaded for more than 20 million for the elixir. Once Yang Kai really refined this thing, he would no longer have to worry about the development of the void in the future.

Two months ago, Yang Kai ordered Yue He to purchase materials for alchemy according to the pill recipe. Qiandou Star Market is a large star market. No matter what goods it is, there are everything there, not to mention that it is backed by an intelligence collection place like the First Stack, so it is not a big deal to purchase materials on the pill recipe.

Now there are 200 pieces of materials for refining the Tianyuan Zheng Seal Pill in the space ring.

This pill is used by warriors in the Emperor Realm and promoted to Kaitian, so the level is not very high, but it was lost due to the extinction of the main material.

With Yang Kai's alchemy level, it is enough to refine the Tianyuan Zheng Seal Pill, but it is hard to say what level it can be refined. Yang Kai did not expect to eat a fat man in one bite and refine any pill-patterned pill cloud. As long as 10% of these two hundred pieces of materials are successfully refined, it will be a great harvest.

After a while, Yang Kai took out some elixir powder. It was what he had scraped off from the Tianyuan Zheng Seal Pill before, pinched some and put them in his mouth to taste it. From the process of refining the medicinal power, all kinds of thoughts in his mind sparked like lightning.

It took a full half month to make a decision and start the furnace to refine the alchemy.

The Tianyuan Zhengyin Pill can increase the chance of a warrior being promoted to Kaitian, and the Tiandi Source Liquid is the same. When Lao Bai was disturbed at the moment of promotion, he almost died. Yang Kai used the Tiandi Source Liquid to pull him back from the edge of life and death.

However, in comparison, the Tianyuan Zheng Seal Pill, refined with the main material of Tiandi Source Liquid, has a stronger effect. It not only allows warriors to appreciate the power of the first opening of heaven and earth, but also has the effect of stabilizing the Taoist seal.

Moreover, a Tianyuan Zhengyin Pill only requires a drop of Tiandi Source Liquid.

In order to save Lao Bai, Yang Kai took two bottles of Tiandi Source Liquid for him. The two bottles of Tiandi Source Liquid could almost refine dozens of Tianyuan Zhengyin Pills, and the consumption was incomparable.

Half a day later, Yang Kai, who was concentrating on refining alchemy, suddenly frowned, smelled a burnt smell, couldn't help but sigh and stopped his hand.

When the fire went out and the alchemy furnace was turned on, the burnt smell was even more intense and almost a bit pungent.

This first refining was a failure. I failed to grasp the temperature at a critical moment and completely scrapped a furnace of materials.

This is also normal. Although Yang Kai’s way of refining alchemy is good, it was the first time he refined the Tianyuan Zheng Seal Pill after all. He was not familiar with all the steps, so he did not expect to be able to refine it in one go. Therefore, he was not discouraged. After taking a short rest, he checked the place where he made a mistake and started the second refining.

Half a day later, the second furnace of materials was also scrapped, and a burnt smell came from the elixir.

This time, Yang Kai did not make any mistakes in the previous steps, but something went wrong in another place.

Alchemy has always been so rigorous that any minor mistake can lead to overall failure. It is precisely because of this reason that no matter where it is, alchemists can be so popular, and the prices of various rare elixirs have always remained high.

In the next month, Yang Kai kept trying to refine the Tianyuan Zhengyin Pill, summarizing experience, improving techniques, and grasping the timing of every moment based on repeated failures.

Every failure can make him reflect for a long time, and every mistake can make him grow.

According to the boss’s previous calculation, the value of this material is almost more than 100,000 except for the Tiandi source liquid. If the Tiandi source liquid is added, it cannot be calculated. At least one million is available.

For such a long time, more than one hundred pieces of materials failed to refine. In other words, more than one million yuan was wasted.

However, this investment is worth it. As long as you can refine the Tianyuan Zhengyin Pill, it will be a continuous way to make money!

Yang Kai couldn't help but think of his junior sister. Although he had some talent in the art of alchemy, his junior sister Xia Ningshang is the holy body of medicine and spirit. She was born to refine alchemy. If she were here, she would definitely be better than herself.

It was not until one day a month later that Yang Kai took out a spiritual pill from the elixir furnace.

This spiritual pill is basically exactly the same as the spiritual pill he got from auction house before. He gently scraped a layer of elixir powder and put it in his mouth to taste. There was no difference in taste or efficacy.

Yang Kai let out a sigh of relief, knowing that he had successfully refined it.

It is not easy to refine the first Tianyuan Zheng Seal Pill in one month.
