After returning to the Terran, Chiyou began to understand the secret of the "Twelve Gods and evil array" given by Xing Tian. The result shocked him. He didn't think that the requirements of the "Twelve Gods and evil array" were so high that it needed ancestral witches to set up the array. The "Twelve gods and evil array" in the later stage of the Lich war was not a complete version. It's impossible for him to set up this array now, The only way is to modify the "Twelve heavenly gods and evil spirits array". After thinking for several times, Chiyou finally came up with a way to change the "Twelve heavenly gods and evil spirits array", that is, to refine twelve heavenly gods and evil spirits flags to replace the twelve ancestral witches to arrange the array. Even so, the power of the large array will be greatly reduced, but the names of the three evil arrays in ancient times are not in vain. It is impossible to resist the power of this array by virtue of the cultivation of the immortals.

Chi you thought it was very good, but the reality was beyond his expectation. After the Twelve Gods and evil flags were refined, the "Twelve Gods and evil array" could not be put up anyway, which made Chi you very angry.

At this time, the great witch Fengbo said, "the Twelve Gods and evil spirits array is based on the twelve ancestors. Although these twelve gods and evil flags are also good treasures, they can't be compared with the twelve ancestors, because they don't have the brand of the twelve ancestors, so they can't arrange the array."

Hearing Feng Bo's reminder, Chiyou suddenly realized that since the Twelve Gods and evil array could not be arranged, he could create another array according to the principle of the "Twelve Gods and evil array".

So Chiyou began to work with the great witch Fengbo and the rain master to study how to create a powerful array based on the principle of the "Twelve heavenly gods and evil spirits array".

After many twists and turns, Chiyou and others finally created the "Xuanyin array" based on the "Twelve heavenly gods and Demons array". This array is a combination of the magic skills of Ashura road. The array uses 13 Xuanyin flags. On each flag, there is a day outside the demon as the flag spirit. Within a hundred miles of the array, it is shrouded by the spirit of Xuanyin, which makes people lost in the Xuanyin array, It is used to attack the 13 demons outside the sky. They are invisible and kill people. It can absorb souls and enhance their own strength.

As soon as this formation was completed, Chi You fell a big stone in his heart. He finally had the ability to compete with the elucidation and held back the elucidation of the immortals. Xuanyuan lost his greatest strength and was not the opponent of the Jiuli tribe army led by Chi you at all.
