"I am the Emperor of Huode, and the compilation of the Book of Changes should be headed by the Hexagram, but in the end I have to be headed by the Hexagram, and I am looking forward to the birth of your Book of Changes."

"Why is this", Feiyang looked puzzled, with what hexagram as the head, it should be his own freedom, why did Shennong say that.

"I am prosperous and prosperous, and then compile a book of changes headed by the hexagram, which will inevitably flourish and decline, so I can only use fire to generate earth, headed by the Gen hexagram."

"I see", Feiyang finally understood why Shennong, as the emperor of Huode, had to write "Lianshan Yi" in the end, but Feiyang still had a question, "What about His Majesty Xuanyuan? He is the emperor of Tude, why is he headed by Kun hexagram in the end."

"Xuanyuan Yellow Emperor is different from me, he was born to expound teaching, and he has Pangu Banner to suppress luck, so he doesn't have to worry about prosperity and decline."

After figuring this out, Feiyang had a better understanding of Yi Dao and even the number of days, and immediately thanked Shennong, left Huoyun Cave with pills and herbs, and hurried in the direction of Xiqi Yingzhai.

After returning to the Xiqi camp, Feiyang couldn't help but breathe a sigh of relief, during the period of Feiyang's absence, Yu Hualong did not send troops to attack the Xiqi camp at all, he should have waited for all the Xiqi army to die, and he didn't spend a single soldier to protect Tongguan.

And after Feiyang entered the camp, he found that Yuding Zhenren and Huanglong Zhenren had come, and Feiyang immediately said, "I just came back from Huoyun Cave and asked for three pills, which can be used for poison gas."

When everyone heard this, they were overjoyed, and quickly watered the three pills, the first one was fed to King Wu, the second was fed to Ziya, and the last one was sprinkled all over the camp.

The next day, Ziya convened the generals to discuss the strategy of breaking the pass, and after seeing the scars on everyone's faces, he was immediately furious, and immediately discussed with everyone to take Tongguan to vent their hatred, and everyone immediately shouted, "If you don't take Tongguan today, you won't return to the army!"

On the eighth day of Yu De's poisoning, he thought that the Xiqi army had been poisoned, so he went out of the city to investigate, and found that the Xiqi army was all alive and vigorous, not at all like a serious illness, although there were scars on the face, but there was no pox, Yu Hualong's family was suddenly shocked, and Yu Delai was counted, if he was not self-righteous, and asked everyone to wait patiently for all the Xiqi soldiers to die, they would have already taken advantage of the other party's pox rash and sent troops to eradicate them.

Yu De is also puzzled by this, his master taught him this technique, it is a hundred tests, who would have thought that they would miss today, however, Yu De thinks that they still have a chance to win, and now the soldiers are recovering from a serious illness, and their bodies are still very weak, as long as they take advantage of this time to attack, they will definitely be able to eradicate them all.

Immediately, Yu Hualong's family led a large army to attack the Xiqi camp, Ziya and others were discussing a strategy to break the pass, but they didn't expect Yu Hualong to call at this time, and immediately gritted their teeth one by one, vowing to eradicate Yu Hualong's family.

Immediately, Ziya led the army to battle, only to see Jin Zha Muzha angry bull fight, Yang Ren had smoke in his abdomen, thunder Zhenzi sound like a thunderbolt, Wei Hu gritted steel teeth, the dragon beard and tiger were angry, Li Jing wanted to choose someone to eat, and all the people rushed up to fight around this father and son.

After a while, Nezha showed three heads and six arms, stepped on the hot wheels, and flew into the city of Tongguan.

Yu Hualong's father and son saw Nezha enter the customs, so they became delirious, and were sacrificed by Lei Zhenzi to the wind and thunder, which hit Yu Guang's head, and pitifully his brain burst and died.

Seeing this, Yu Da's eyes were red, and he came to fight Lei Zhenzi, but Wei Hu took the opportunity to sacrifice the demon pestle, beating Yu Da to death, and his flesh and blood flew sideways, and at this time, Yang Ren fanned the five fires and seven birds, and Yu Xian and Yu Zhao immediately turned into flying ashes.

Yu De saw that all the four brothers were killed in battle, so angry that the three corpse gods jumped violently, and there was smoke in the seven orifices, and immediately rushed straight to Ziya, Ziya saw this, and hurriedly sacrificed the whip of the gods, knocked it to the ground, and was seen by Li Jing, and immediately stepped forward and stabbed it to death with a halberd, Yu Hualong saw that all five sons were killed, and Tongguan had returned to the western soil, and immediately killed himself with a sword.

After Yu Hualong's death, Ziya led the troops into the customs, went out of the list to settle the people, and checked the treasury.

When Feiyang saw Tongguan, he was immediately shocked, because next, what they had to face was the Ten Thousand Immortal Array, and in this big array, even Da Luo Jinxian was pinched to death like an ant, not to mention his small Mahayana period of scattered cultivation, so he immediately found Ziya and told Ziya that he was going to retreat in this Tongguan for a year and cultivate a great magical power, so that it would come in handy in the future, so he would not continue to go out with the army.

Ziya didn't know about the Wanxian Array at this time, and when he heard this, he had no reason to refuse, so he immediately agreed, and found a good house in Tongguan as a place for Feiyang to retreat.

A few days later, Yuding Zhenren came to tell Ziya, saying that the Tongtian Sect Master had set up a Ten Thousand Immortal Array in front of him, preparing to obstruct the army's eastward crusade, as soon as he heard this, Ziya immediately remembered Feiyang who had retreated, and immediately said with a disgruntled face, "You are easy to be a person, you are really a gentleman who does not stand under the dangerous wall, this time the Immortal Array was like this, and this time the Ten Thousand Immortal Array is the same."

And on this day, Ziya sent Wu Ji to come to the outside of the pass, set up a reed tent to wait for the arrival of the immortals, and finally came Guangchengzi, Red Sperm, Manjushri Guangfa Tianzun, Fuxian Zhenren, Cihang Daoren, Qingxu Dao Zhenjun, Taiyi Zhenren, Lingbao Grand Master, Daoxing Tianzun, Fear Liusun, Yunzhongzi, and Burning Lamp Daoren.

At this time, the Holy Mother of Jin Ling was in the Ten Thousand Immortal Array, and saw three flowers on the top of the Daoist who lit the lamp, and rushed into the air, knowing that the disciples under the Yuxu Sect were coming, and immediately sent a palm thunder, vibrating the Ten Thousand Immortal Array, and the smoke was filled in an instant, and tens of thousands of strange-shaped, blue-faced and fanged Taoists came out of it.

Randen immediately said to everyone, "Fellow Daoists, let's take a look, what kind of people from this sect are, how can they be a little like people in the Pure Immortal Dao."

Immediately, everyone came to watch the battle, but unexpectedly a disciple named Ma Sui came out to provoke, Huanglong Zhenren was furious, and immediately fought a sword to take Ma Sui, but Ma Sui sacrificed a golden hoop, put Huanglong's real head in the hood, and then silently chanted a spell, which made Huanglong Zhenren have a headache.

However, at this moment, the Yuan Shi Tianzun came, and when Ma Sui saw the Yuan Shi Tianzun, he was immediately shocked, and quickly retreated into the Ten Thousand Immortal Array.
