After covering the alchemy furnace, Zhou Lei pinched the immortal formula, activated the immortal array under the alchemy furnace, stirred up the Dan fire, and began alchemy.

Zhou Lei didn't know how to do alchemy, but he simply started the alchemy furnace and placed the medicinal materials, and he still understood something. It's just that Zhou Lei didn't know that when alchemy, placing medicinal materials was not as simple as indiscriminately putting them in the alchemy furnace, nor was it stirring up the Dan fire, so he left it alone. It's just that Zhou Lei finished all this according to the last steps.

In the end, Zhou Lei arranged eighteen prohibitions in the alchemy room, eighteen prohibitions on hiding from the sky and crossing the sea, and eighteen prohibitions on the end of the world.

The last time the nine pills were formed, the nine realms were immovable like a mountain of prohibitions, the nine realms were forbidden to hide from the sky and the sea, and the nine realms were close to the end of the world, and none of the nine pills could trap the nine pills. This time, just in case, Zhou Lei arranged some more prohibitions, so that Zhou Lei could be at ease.

…… ，……。

The Pure Demon Pool is a sacred place in the fairy world. Only those with deep merit can enter the Pure Demon Pool. To enter the Pure Demon Pool once, you need to consume 500,000 merit points. And the Seven Mile River God can get 500 merit points a year. I calculated it before, and it took Zhou Lei to be the god of the Seven Mile River for about a thousand years. Later, Zhou Lei made a fortune and obtained 10,000 merit points. Coupled with the period when Zhou Lei was the god of the Qili River, there are also merit points obtained by participating in the battlefield, a total of 200,000 merit points. There are still 300,000 merit points, and you can enter the Pure Demon Pool to save Kang Tiantian. 300,000 merit points, that is, 600 years left, can be completed.

Only later, Zhou Lei met His Royal Highness Kunxuan Wu and Mian'er. In order to refine the Ultimate Pill, it took four or five hundred years. In addition, His Royal Highness Kunxuan went to Heaven to identify the medicinal effects of the Extreme Pill, which delayed some time. In this way, there are still about two or three hundred years left to accumulate enough merit points. When the time comes, you can resurrect Kang Tiantian.

The role of the Extreme Pill can be big or small. If you let it improve its cultivation, you can reach the realm of the late stage of the Great Luo Golden Immortal. And there is not the slightest hidden danger, you can continue to improve your cultivation. If you are small, it is also feasible to have long hair. Especially at critical moments, the Extreme Dan can be said to be able to bring the dead back to life, and the magic is endless.

Zhou Lei still had eight extreme pills in his hand, but he didn't dare to give them to Kang Tiantian. After all, it was Kang Tiantian, Zhou Lei couldn't bear it, and he was not willing to take Kang Tiantian at risk.

For the sake of safety, Zhou Lei still has to take Kang Tiantian to the Pure Demon Pool to resurrect Kang Tiantian.

As for refining the elixir and the ultimate pill for His Royal Highness Kunxuan, Zhou Lei didn't pay attention to it. After all, Zhou Lei had eight Extreme Pills in his hands. Therefore, whether the refining of the Ultimate Pill can be successful this time, Zhou Lei doesn't care.

Two or three hundred years is a long time, but in Heavenly Court it is short after all. After all, one day in the sky, a year underground.

The Pure Demon Pool is a sacred place in the fairy realm, and it is naturally in the heavenly court. The Heavenly Court is vast and boundless, and the Pure Demon Pool is in the north of the Heavenly Court. Zhou Lei entered the Heavenly Court from the Five Elements Immortal Sect, and it would take a long time to reach the Pure Demon Pool. At that time, two or three hundred years had passed. Therefore, Zhou Lei quietly left Qingxian Peak, entered the heavenly court through the Five Elements Immortal Sect, and rushed to the Pure Demon Pool non-stop.

Zhou Lei's current cultivation is in the late stage of Xuan Immortal, and his flight speed in the Heavenly Court is naturally very fast. But the Heavenly Court is too big, and the Pure Demon Pool is too far apart. It takes two or three hundred days, that is, two or three hundred years in the Nether.

Zhou Lei's departure, no one noticed. Zhuang Li'er, Huang Xiao, Bing Lan, and Bing Xin were busy preparing things for Mian'er's marriage, and His Royal Highness Kunxuan was also busy. And they all thought that Zhou Lei was still refining the Extreme Pill in the alchemy room, but they didn't expect Zhou Lei to leave the Extreme Pill and run away.

Zhuang Li'er, Huang Xiao, Bing Lan, Bing Xin, were a little hesitant in their hearts, but Mian'er's marriage was busy, so I forgot about these hesitations.
