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. Now because of Zhuang Li'er, Huang Xiao, Bing Lan, and Bing Xin, it took Zhou Lei a hundred years to go back and forth to Qingxian Peak.

Since Zhuang Li'er, Huang Xiao, Bing Lan, and Bing Xin are safe and sound, and they are blessed by misfortune, then Zhou Lei also has to take Kang Tiantian to the Pure Demon Pool.

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. According to Zhou Lei's current cultivation to the late stage of Xuan Immortal, the 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. If it is extremely fast, it will take more than 100 years.

Above the Heavenly Court, the Heavenly Court, the center of the fairy world. It is surrounded by layers of clouds, pavilions, looming. The Xianting Mansion can be seen everywhere. High, trees can be seen fluttering. Low, you can see the undulating peaks. Cranes fly, colorful birds fly low, and fairy beasts step on the clouds. Between the comings and goings, the heavenly soldiers and heavenly generals, majestic and deterrent. Immortal fairy wind bones, come and go like flying. Streamers pierced the clouds, and wisps of colorful glow illuminated the sky.

Zhou Lei's sword flew extremely fast, like a streamer piercing the clouds, and the palace never stopped.

More than a hundred years is just more than a hundred days for Heavenly Court. As time passed, Zhou Lei encountered fewer and fewer palaces. Although the air is full of fairy energy, it is indeed less popular.

The Heavenly Court is so vast, it's no wonder that there are few battles. After all, when the place is bigger, there are fewer people, and when there are fewer people, there will be fewer troubles.

More than a hundred years later, Zhou Lei rushed to the Pure Demon Pool. The Pure Demon Pool is a sacred place in the fairy world, and it is naturally guarded by heavenly soldiers and generals.

"This is, the Immortal Holy Land Pure Demon Pool, come and stop. A heavenly general said, armed with a spear.

"This Heavenly General, I'm going to use the Pure Demon Pool. Zhou Lei put away the Bumen sword and said.

"The Pure Demon Pool is a sacred place in the fairy realm. Only those with deep merit can enter the Pure Demon Pool. Entering the Pure Demon Pool once, you need to consume 500,000 merit points, are your merit points enough?" This heavenly general saw the speed of Zhou Lei's sword's flight, and knew that Zhou Lei was not an ordinary person, so he didn't feel embarrassed, just business.

"Naturally prepared enough. Zhou Lei smiled and took out his identity jade card.

"Seven miles of river god, idle Taoist Zhou Lei. The heavenly general looked at Zhou Lei's jade plate and said.

"Yes, it's down there. Zhou Lei nodded and said.

"500,000 merit points are indeed enough. You are sure to spend 500,000 merit points to enter the Pure Demon Pool. The Celestial General confirmed here.

"Not bad. Zhou Lei replied.

"Okay, 500,000 merit points have been deducted, and you can go in. After deducting the 500,000 merit points in Zhou Lei's jade pendant, the heavenly general handed Zhou Lei's jade plaque.

"Thank you. After Zhou Lei took the jade card, he thanked him.
