Liu Chengzhi saw that he was depressed, so he tried to distract him and asked, "Senior Wang, you just said that there is a law of heaven and earth here, I don't know how you found it?"

Wang Xinyi stretched out his right hand, and saw a red gemstone ring on his thumb, and the ruby was shining brightly.

At this time, Xuanqi Baojian also emitted a yellow light, and the voice of the pot also appeared in Cheng Zhi's mind: "Cheng Zhi, there is indeed the law of heaven and earth here!"

Liu Chengzhi hurriedly said: "Senior Wang, let's not hesitate, without further ado, quickly find out the law!"

Wang Xinyi hurriedly said yes, and the two began to look for it in this secret room.

At this time, Liu Chengzhi found a small protrusion on the central wall of the secret room, he moved in his heart, pressed it, and only heard the sound of "bell!"

The two did not hesitate and immediately rushed into the cave.

Inside the cave is a huge desert, the wind and sand blow, the heat is pressing, but the laws of heaven and earth have not manifested, so the two of them did not find it at all.

The two of them walked in the desert for about half an hour, but found nothing.

At this time, a gloomy gate suddenly appeared in front of the two.

Wang Xinyi secretly screamed badly, took Liu Chengzhi's hand and stepped back.

There was only a "bump" sound, and the place where the two of them had just stood was struck by the flames from the gate, and a large crater was blown out.

Liu Chengzhi just wanted to ask what was going on, but he saw the gate slowly open, and a burly general in gold clothes, holding a blood-red machete in his hand, walked out of the door.

Wang Xinyi shouted: "Liu Chengzhi, you go back first, he is the god of war, you are not an opponent!"

When Liu Chengzhi heard this, he was taken aback.

The god of war laughed and said, "Don't let any of you go!"

With that, he pointed with his right index finger, and saw that the entrance to the cave where they had entered was suddenly sealed, and the gloomy gate was gone.

The god of war looked at the world with a look of intent, and said to Wang Xinyi: "Wang Xinyi, we meet again! I didn't expect you to be able to kill Wu Yong and Yan Nu today! I really made me look at you differently." I'm still the same, would you like to be my doppelganger?"

Liu Chengzhi shouted angrily and said, "I killed both of them, and you came at me for anything!"

The god of war smiled and said, "Then I can't even think of it!"

But the afterglow of his eyes stayed on Liu Chengzhi for a moment, and he couldn't move away, and said: "Unexpectedly, the five elements physique, the extreme refining body of the twenty-three meridians, and the twenty-ninth level of spiritual power actually appeared in your little boy at the same time!"

He pondered for a moment and said, "As long as either of you agree to become my God of War clone today, I will spend a lot of effort to cultivate!"

Wang Xinyi sneered and said, "You died of this heart!"

Liu Chengzhi laughed and said, "Why can't you be my doppelganger?"

When the god of war heard this, he couldn't help but be furious: "Hmph! Toast and don't eat penalty wine! Okay, I'll let you see what it means to be high and thick today!"

With that, snapped his fingers.

Liu Chengzhi only felt that the skeleton of his body was gurgling, and his knees were gradually bent, and there was a tendency to bow down to the god of war.

But he used all his strength to resist this feeling with all his might!

The god of war saw them fighting to the death, and just wanted to snap his fingers a second time.

I only heard the sound of "zi", and Liu Chengzhi's chaotic qi diagram flew out of his arms, hung it in the air, and unfolded automatically, and then a Taoist with a crane hair and a childish face walked out.

"Yu Yidao! You're here! Let's compete today!" said the god of war, gritting his teeth.

Yu Yidao grinned and said: "God of War, you are now a god to control qi, and your strength is not as good as one-ten-thousandth of usual! And I am a wisp of remnant soul, and I can use one percent of my strength! Do you think you can beat me?"

The god of war said: "Don't talk nonsense, look at the knife!"

After that, a knife was slashed, and the entire desert was suddenly covered with wind and sand, showing a cyclone, blowing towards Yu Yidao.

Yu Yidao saw this move, but he didn't dare to slack off, put his hands together, slowly moved his hands over his head, and slashed forward, only to see nine lightning bolts fly out of Yu Yidao's palm, each lightning showed a giant dragon, nine giant dragons, opened their big mouths, stretched out their front paws, and rushed towards the desert cyclone.

I could only hear a few loud bangs, and the whole desert was covered with yellow sand, and I couldn't see my fingers, and this lasted for a full hour.

Finally, the wind and sand gradually stopped, and Wang Xinyi and Liu Chengzhi were able to raise their heads and see the surrounding situation clearly.

I saw that the giant knife on the back of the god of war was no longer in his hand, but was inserted in his own chest, and blood was dripping from the corner of his mouth, and he slowly fell to the ground, and then disappeared into the desert.

Yu Yidao turned his head, looked at the two of them, and said, "My mission has been completed, whether I can find the law of heaven and earth next, it depends on your understanding!"

"But I can't help, otherwise it will be against the principles of heaven, no different from the god of war, and I will leave!"

After that, he slowly walked into the Chaos One Qi Diagram, the Chaos One Qi Diagram rolled up, and then returned to Liu Chengzhi's arms.

The two continued to search for the law in the desert, but after searching for a long time, they still found nothing.

Liu Chengzhi couldn't help but stop and asked Wang Xinyi: "Senior Wang, may I ask what are the four laws at the top of the Demon Suppression Pagoda, do you know?"

Wang Xinyi said: "I didn't know before, but after thirty years of fighting with the God of War clone, I slowly learned that these four laws are 'light', 'darkness', 'yin', and 'yang'!"

"And according to some seniors, Yu Yidao's predecessors have found the 'yin' law!"

Liu Chengzhi said: "I heard Yu Yidao's predecessor talk about it, he found the law in the Yunhai Snow Field, and the name of this law is 'Yin', that's right!"

Liu Chengzhi suddenly realized and said: "We have entered this Heartless Cave Mansion, and we feel that Yang Qi is pressing, and this must be the law of 'Yang'!"

"So what is the best representation of 'yang' in this desert?"

He pondered for a moment, then set his eyes on the sun in the sky.

"The desert is only when there is a sun, and the yang energy is pressing! Besides, we are always in the cave, how can there be a sun?"

Thinking of this, Liu Chengzhi stood tall and pointed his palms at the sun in the sky.

Slowly, the sun's rays faded, and the piercing sensation faded into a soft glow.

At this moment, the whole earth began to shake, and the desert where they were suddenly disappeared.

Liu Chengzhi's entire arm was entwined with a vast energy, constantly radiating a scorching light, making Liu Chengzhi's entire body exude a divine aura.

Wang Xinyi was overjoyed and said, "Liu Chengzhi, you have found it!"
