Under normal circumstances, it will rain before dark clouds can condense and then lightning will be generated. Moreover, the changes in the celestial phenomena are a large area and will take a long time to brew. But at this time, the black clouds above the mountains are extremely abrupt, and lightning only falls to the same place when they are targeted, which is obviously abnormal.

"This desert is so dry, there are no lakes and plants within hundreds of miles. It's impossible to rain, right?"

Lu Xin looked up at Tianji and spoke with frowns fiercely. Monk Yan Cen stopped the movement in his hand and then took the words over.

"This is the heavenly tribulation of the tiger demon, which will occur every 7749 years. No wonder he will go to the city today to plunder the people. He should have wanted to use human flesh and blood to spread his vitality after the heavenly tribulation."

"The heavenly tribulation? The cultivation of the tiger demon has reached the point where it can trigger the heavenly tribulation?"

Lu Xin's face changed slightly. The heavenly tribulation is an obstacle for heaven to practitioners. In other words, God does not like creatures on the earth. He can cultivate to the point where he can fly to the sky and escape, or even break through space and ascend to the upper realm. Therefore, he will reduce various tribulations and punishments in the process of living creatures to hinder his practice. Li Chunfeng once said that when the Onmyoji practices to a certain level, he will cause thunder tribulation. But the first thunder tribulation is also when the Great Perfection of the Return to the Micro Realm is needed to break through to the God Realm. If the cultivation of the tiger demon is already strong and can trigger thunder tribulation, how could he be his opponent?

Monk Yan Cen seemed to see Lu Xin's concern, bent down and buried the last talisman in the sand, signaling Lu Xin to sit down.

"The demons are different from humans. The demon clan has a strong body and a long life span. Compared with our human clan, they have many advantages. The fair way of heaven will bring down more tribulations to hinder the monster's cultivation. The thunder tribulation that appears once every 7749 years is a heavenly thunder that transforms the body of the tiger demon and its method of the Huntian Xuan Gong. With his cultivation level, the thunder tribulation should be able to pass it. But after the thunder tribulation, he must have been greatly damaged, which is the weakest moment of his destiny. Now I understand why Xuanzang asked you and me to enter the mountain to collect monsters in these two days."

After saying that, Monk Yan Cen slowly closed his eyes. Compared to this, his expression was obviously much relaxed. Lu Xin also breathed a sigh of relief after hearing the words. The weaker the tiger demon, the safer he was. The appearance of the heavenly tribulation is undoubtedly a favorable phenomenon. But in the same way, if Xuanzang even clearly calculates the matter of the tiger demon passing the heavenly tribulation, then this monk's Taoist practice would be too terrifying.

The thunder clouds over the mountains lasted about half an hour before slowly dissipating. The sky returned to normal, but the sunlight was obviously weakening little by little. After that, Monk Yan Cen waited for another hour before standing up and signaling Lu Xin to follow. The two walked towards the mountains in the distance. Although there was nothing wrong, the boy's heart was still hanging. What if the tiger demon had eaten the little monkey? What if the tiger demon who had survived the heavenly tribulation became stronger?

Lu Xin is actually not a sentimental person, but when he has too many concerns, the burden on his back will naturally be heavy. The little monkey has saved him. If he cannot bring it out of the tiger demon, Lu Xin will be uneasy for the rest of his life.

According to Monk Yan Cen, the mountain range in front of you is called Tulong Mountain, which is the largest and only mountain range in this desert. It is about a hundred miles long from east to west, and the highest mountain is called Hu Xiao Peak, which is also the location of the tiger demon's nest and the Black Wind Cave.

The terrain of Tulong Mountain is not steep and there are few plants and trees. For Onmyoji like Lu Xin and Monk Yan Cen, the road to the mountain is not difficult to walk. At the beginning of Shen Shi, the two of them walked to the Black Wind Cave. At this time, the sun had already set off, and the yang energy between heaven and earth gradually faded.

Monk Yan Cen paused in front of the cave for a moment, and used a golden paint to draw a Buddhist talisman on Lu Xin's chest. It is said to be the mantra of the Tiger and Arhat, with powerful Buddha power. Lu Xin asked himself that his cultivation was insufficient, and that You Xianjian had been taken away by Naihetian, so he just did whatever the old monk could do.

"Okay, let me in and do everything with caution."

The Black Wind Cave is a naturally formed wind-formed cave on Tiger Roar Peak. This is not uncommon in arid desert area. The diameter of the cave is four or five meters wide. As soon as Lu Xin enters it, he feels gusts of cool breeze coming. Moreover, the moisture in the air is very sufficient. In other words, there is a source of water in this cave.

The road under your feet always tilted downwards, and the deeper you go, the more you smell it is. About five hundred meters away from the entrance of the cave, a large number of bones began to appear on the ground. Some animals and some people were. Only then did Lu Xin truly understand the terror of monsters at this time.

"Here, turn the corner in front of me and it is the tiger demon's nest. I think he should have discovered you and me."

Monk Yan Cen suddenly stopped and pointed to a light not far away and said. When Lu Xin heard this, the light at the corner flickered and darker, like a candle blown by the wind, swaying and extinguishing at any time. He was about to urge Monk Yan Cen to continue walking forward, but just as he was about to speak, a sensational grin sounded in his ears.

"Hehehehehehehehehehehehehehe...Monkey Yan Cen, today, is he going to drink a bowl of delicious human flesh soup with me? Or come and show his compassion and take these people away? If it is the latter, I think you may not be far from seeing the Buddha Lord of the West."

After the grim laughter, Lu Xin was almost before he could come back to his senses, and then he flew forward quickly without saying a word. When he landed on the ground again, he had already arrived at the other end of the corner. He stood up and looked around. In front of him was a huge cave with a radius of more than a hundred steps. In the center, he set up a big pot and was cooking the rolling soup. A middle-aged man in black was sitting casually on the stone in front of the pot. His hair was very long, almost reaching his waist. His eyebrows were like peaks, his pupils were as strong as abyss, and his momentum was really unfathomable.

In addition, behind the man in black, there were five people lying, and the little monkey was among them, but he didn't know whether it was life or death. Lu Xin was a little excited and took a step forward suddenly, but was immediately blocked by Monk Yan Cen.

"My Buddhism takes it as its mission to save all sentient beings and never kill innocent people indiscriminately. You are already a demon king who has achieved success in practice and no longer be confused. Taking people as a means of feeding on heaven and harmony after all."
