Chapter 331： Xuan Rank Seal Book (1/2)

Chapter Three Hundred and Thirty One

Xiao Chao returned to Xiaoyaoyuan and immediately began to study the'Demon Heart Covenant'.

The Demon Heart Covenant needs to be branded on a scroll made of a special material, so the material also needs to be carefully considered and polished carefully to distribute the zhenqi evenly.

Therefore, Xiao Chao carefully selected it, and finally took out a demon wolf skin.

Zhen Qi appeared on the palm of his hand, and Xiao Chao's palm was like a blade, tracing the demon wolf skin, carefully polishing it.

laugh.

Xiao Chao's strength was a little bit stronger, and a dent that was difficult to distinguish with the naked eye appeared on the demon wolf's skin.

"No, this one is ruined!"

Xiao Chao sighed.

Although it was only a trivial dent, it was enough to ruin the'Demon Heart Covenant\'.

"Come again!"

Xiao Chao made persistent efforts.

Sealing the coat of arms, Xiao Chao can use the mobile phone to take pictures, making it simple, but he needs to personally choose materials and polish them.

After more than a dozen consecutive scraps, Xiao Chao finally got a good animal skin, and then began to make the'Demon Heart Covenant'.

He found the photo of the'Demon Heart Covenant' and injected true energy into it.

This time, Xiao Chao immediately felt the true Qi in his body flow quickly, as if the'Demon Heart Covenant' coat of arms in his hand turned into a bottomless pit, devouring Xiao Chao's true energy madly.

"Although it is a kind of heart oath, the covenant made under the agreement of both parties will consume the least amount of qi, but if you want to be able to punish the Demon King, it will inevitably require Demon King-level power." Hey! Words! brother

Xiao Chao was not surprised, the true energy in his body was madly injected into the Demon Heart Covenant.

It didn't take long, but the true energy in Xiao Chao's body was rapidly consumed.

In a short while, a demon heart covenant appeared in the palm of Xiao Chao's palm, and then it was pressed on the demon animal skin that had been prepared a long time ago.

boom.

With a loud noise, the furniture in Xiao Chao's room was blown up, and the'Demon Heart Covenant' made this time also failed.

"what happened?"

Xiao Chao showed doubts, unwillingly picked up a few fragments, and carefully checked them.

In the end, Xiao Chao found the reason.

It wasn't that Xiao Chao was not good enough to polish the animal skins, but that there was a problem with the selected materials.

On the animal skin he selected, there was a silky texture, which should be a scar that he had suffered before. It was this scar that destroyed the material and caused the power to be unbalanced.

"It's really difficult, not even wanton mistakes!" Xiao Chao shook his head, and said, "It seems that I am still the most suitable seal coat of arms that can be placed directly with infuriating energy without materials!"

In the end, Xiao Chao took a rest for more than an hour, his Zhen Qi returned to its peak state, and began to polish animal skins again.

After several damages, it finally succeeded once.

This time, Xiao Chao could be described as carefully selecting and confirming that the materials were not flawed, and only then began to make the'Demon Heart Covenant'.

Zhen Qi was consumed wildly again. Soon after, a ‘Demon Heart Covenant’ appeared in Xiao Chao’s palm, and then he pressed a palm on the animal skin.

boom.
