Wen Hao returned to the Escape Courtyard and immediately began to study the 'Demon Heart Covenant'.

The Demon Heart Covenant needs to be imprinted on the scroll of a special material, so the material also needs to be carefully considered, and careful polishing can make the true qi evenly distributed.

Therefore, Wen Hao carefully selected and finally took out a demon wolf skin.

True qi appeared on the palm of his hand, and Wen Hao's palm was like a blade, cutting through the skin of the demon wolf, carefully polishing.

Laugh at.

Wen Hao's strength was slightly greater, and a dent appeared on the demon wolf skin that was difficult to distinguish with the naked eye.

"No, this piece is ruined!"

Xiao Chao sighed.

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

"Come again!"

Wen Hao made persistent efforts.

Sealing the coat of arms, Xiao Chao can use the function of a mobile phone to take pictures, simplifying the complex, but selecting materials and polishing materials requires him to do it himself.

After scrapping more than a dozen in a row, Wen Hao finally got a good animal skin, and then began to make the 'Demon Heart Covenant'.

He found the picture of the 'Demon Heart Covenant' and injected true qi into it.

This time, Wen Hao immediately felt the true qi in his body flying, as if the 'Demon Heart Covenant' heraldic in his hand had turned into a bottomless pit, frantically devouring Xiao Chao's true qi.

"Although it is a kind of heart oath, the covenant made with the consent of both parties has the least consumption of true qi, but if you want to be able to punish the demon king, you must also need the power of the demon king."

Wen Hao was not surprised, the true qi in his body was frantically injected into the demon heart covenant.

The time was not long, but the true qi in Wen Hao's body was consumed.

After a while, a demon heart covenant appeared in Wen Hao's palm, and then pressed it on the demon beast skin that had been prepared a long time ago.

Bang.

With a loud bang, the furniture in Wen Hao's house was blown up, and the 'Demon Heart Covenant' made this time also failed.

"What's going on?"

Wen Hao looked puzzled, unwillingly picked up a few fragments and examined them carefully.

In the end, Wen Hao found the reason.

It's not that Wen Hao isn't good enough to polish the hides, but that there is a problem with the materials selected.

On the animal skin he selected, there was a silk-like texture, which should have been a scar from the past, and it was this scar that destroyed the material and caused the power to be unbalanced.

"It's really difficult, and you can't even make mistakes and omissions!" Wen Hao shook his head and said, "It seems that I am still the most suitable for those sealing seals that can be arranged directly with true qi without materials!" ”

In the end, Wen Hao rested for more than an hour, and his true qi returned to his peak state, and he began to polish the animal skin again.

After a few damaged, I finally succeeded once.

This time, Wen Hao can be said to have carefully selected and made sure that the materials were not defective, and then he began to make the 'Demon Heart Covenant'.

True Qi was once again consumed wildly, and not long after, a 'Demon Heart Covenant' appeared in Wen Hao's palm, and then pressed it on the animal skin.

Rumble.

The Demon Heart Covenant centered on Wen Hao's palm, spreading out around the animal skin, and finally condensed into shape.

"Ding, get a demon beast covenant, and you can make an oath with the level 1 demon king!"

A prompt also appeared on the phone.

"Finally it worked!" Wen Hao checked it again, and now the seal seal is not flawless.

It's not that there is a problem with heraldry, the problem lies with Wen Hao and the material.

Because Wen Hao's true qi is not enough, and he is not as pure as the Martial King, the power of the 'Demon Heart Covenant' is not strong. In addition, the skin of the demon beast is a little worse, and to make a Xuan-level seal seal, it is best to make the skin of the demon king, or the material for forging the king's weapon.

"However, with the strength of the Martial Sect, it is very rare to make a Xuan-level seal seal, and I heard that it is difficult to produce one in the Heaven and Earth Sacred Courtyard in hundreds of years."

Wen Hao was not disappointed.

In the next few days, Wen Haoyou practiced more than a dozen times, made more than a dozen scrolls of the 'Demon Heart Covenant', polished hundreds of finished animal skins, and went to the Sealing Soul Courtyard again.

"Is it really here? What do you think? Learned the Demon Heart Covenant? When the old man saw Wen Hao coming, he couldn't help but show a look of emotion.

If you dare to come, you will definitely achieve something.

"Well, I've mastered the Demon Heart Covenant!" Wen Hao said.

"I've got it!" The old man's eyes flashed, and then he took Wen Hao and came to Huayue's room next to him again.

Hua Yue's eyes lit up when she saw Wen Hao coming, and she said, "Come, show it!" Ben Meow waited. ”

"Wait a minute, senior!"

Wen Hao nodded, took out a piece of animal skin, and the palm of his hand was attached to the true qi, and he was very skillful and repeatedly polished it several times, and a smooth surface of the animal skin was formed.

Then, Wen Hao put the scroll on the table, the true qi was running, and a 'Demon Heart Covenant' immediately appeared in the palm of his hand, and with a 'bang', the 'Demon Heart Covenant' was pressed by Wen Hao on the animal skin, and the pattern of the seal seal spread out, and finally spread throughout the entire animal skin, and a 'Demon Heart Covenant' was completed.

Wen Hao's movements were completed in one go, without half a minute of hesitation and pause.

On the side, Hua Yue and the old man's expressions were already quite moved.

After the 'Demon Heart Covenant' was made, Hua Yue picked up the scroll with her claws, looked at it carefully, nodded with satisfaction, and said, "I don't need to try, I can see that this palm 'Demon Heart Covenant' can restrict the Demon King or Martial King of Level 1!" ”

"Show me!" The old man also couldn't wait to snatch the scroll from Huayue's claws, and when he looked closely, he was even more full of praise, and said: "Genius, sure enough, genius, Heaven and Earth Holy Courtyard, no, there has never been such a person in the entire Tianwu Great 6."

If it weren't for the lack of skill and material limitations, such an accurate seal sigil would be enough to control the 1o level demon king, and it would be a perfect seal crest! ”

The old man's eyes lit up and he was full of praise.

"Senior, I can join the Soul Sealing Academy!" Wen Hao said.

A few days ago, the level was undecided, and Wen Hao's information had not been filled in, and he had not officially joined the Soul Sealing Academy.

"Yes, of course!" The old man hurriedly took Wen Hao back and wrote Wen Hao's Soul Sealing Master realm into a Xuan-level 1 grade.

Xuan-level spirit sealer, there are only 3 grades, Wen Hao is currently the lowest level, but as long as Wen Hao's skill improves later, it will naturally improve.

"Also, this is the Xuan-level seal book promised to you!" The old man took out another sealed book.

"The Book of the Fu Emperor's Seal".

Wen Hao took a look, there are not many contents in this seal book now, but all the seals recorded are Xuan-level seal seals, and there are more than a dozen kinds of seal seals that can seal the Demon Emperor, and they all seem to be seal seals without materials.

"It's just right for me!" Wen Hao was overjoyed, and then thanked the old man.

"This is the Soul Sealing Academy Student Token, with this token, you can complete some tasks of the Soul Sealing Academy, go to the 2nd floor of the Hidden Scripture Pavilion to watch the Xuan-level Seal Book." The old man took out a token printed with the word Sealing Spirit 2, opened it, and said, "Let's go, I'll take you to see the courtyard master, your talent is enough to become the chief of the Sealing Spirit Academy!" ”
