The Seven Demon Lords seemed to see the dissatisfaction in Duan Chen's heart, and said with a smile: "Don't underestimate this Ancient Heavenly Demon Pattern, as one of the oldest Demon Patterns in the world, its level is so high, even if you look at the entire Space-Time Realm Sea, it is definitely enough to rank in the top three." ”

"Is it really so powerful?" Duan Chen's eyes flashed with suspicion, obviously a little disbelieving.

"There are many kinds of magic patterns, among which the ancient magic pattern is undoubtedly the highest one, but no matter which kind of magic pattern it is, it can be divided into two kinds, one is the inherent magic pattern, the other is the advanced magic pattern, and the ancient heavenly demon pattern belongs to the latter. ”

The Seven Demon Lords said slowly: "What I just passed on to you is the earliest level of the Desolate Ancient Heavenly Demon Pattern, and after that, as you continue to cultivate, this Ancient Heavenly Demon Pattern will continue to advance, and its final form is the real Desolate Ancient Heavenly Demon Pattern." ”

"I see. Duan Chen was stunned, then left the space-time altar and returned to the outside world, handing over the list of materials needed to engrave the Desolate Heavenly Demon Pattern to the old village chief.

However, after the old village chief finished reading the list of materials Duan Chen's needs, his face couldn't help but become quite strange.

"Is there a problem?" Duan Chen saw the clue.

"Sir, the material on this is ......," the old village chief said with some difficulty, "Very expensive." ”

"Very expensive?" Duan Chen was stunned.

The materials on the list are all some magic materials told to him by the Seven Demon Lords, and he himself knows a little about the value of these magic materials, and now when he heard the old village chief say this, he realized that this magic material is only afraid that it will not be easy to collect.

"Yes, these magic materials that Mr. needs are very expensive, like the first kind of magic material magic silver grass, the old man has only heard of it in the past, and has never seen the real thing, as for the rhino demon horn, the old man has never seen it, and there is no ...... in ordinary towns" The old village chief shook his head again and again.

"Can you buy it?" Duan Chenlian asked.

He obviously cares more about whether he can buy it than the problem of high price, as for the magic stone, although he doesn't have it in the storage ring, but in the Southern Regions, some big towns support the exchange of spirit stones for magic stones, so the problem in this regard is not very big.

"As long as there are enough magic stones, the old man knows where to buy them. The old village chief nodded.

"In this way, it will trouble the old village chief to run for me. Duan Chen couldn't help but breathe a sigh of relief when he heard this, and at the same time asked the ghost ghost to set off with the old village chief.

After all, the magic materials they want to buy are worth a lot of money, and the old village chief alone is afraid that it will not be enough to escort him back to the village safely.

As for Duan Chen himself, most of the injuries in his body have now healed, at least there is no problem in walking on the ground, and he doesn't need to carry it on his back at all times.

After sending off the old village chief and the ghost, Duan Chen returned to the space-time altar to continue his cultivation.

One year inside the altar of time and space, but only one day outside.

However, except for the first time when it took a year to open the space-time altar, the rest of the time period was normal cultivation.

After more than half a month like this, Ghost and the old village chief rushed back to the Moon Demon Village with a dusty face.

It can be seen that after this outing, the old village chief is obviously in awe of ghosts, and he is also very restrained in his speech, obviously he has seen the strength of ghosts.

However, Duan Chen didn't care much about this, he took the demon materials he collected from the old village chief, and went directly into the mountains and rivers, preparing to engrave the demon pattern on the body of the Blood Demon True Monarch and divide the demon thoughts.

Mountains and rivers, the cave world, on the altar of time and space.

"Have you thoroughly studied the Soul Splitting Technique and the Ancient Heavenly Demon Pattern that I taught you?" asked the Seven Demon Lords with a solemn expression.

"It's all understood. Duan Chen nodded. Qiqi Chinese Network

"Let's get started. The Seven Demon Lords didn't talk nonsense, with a wave of his palm, the body of the Blood Demon True Monarch immediately appeared on the space-time altar out of thin air, still lifelike, as if it was still alive, but without the breath of life.

Duan Chen took a deep breath, adjusted his mind, and began to engrave the Ancient Heavenly Demon Pattern on the Blood Demon True Monarch's body.

The Initial Rank of the Ancient Heavenly Demon Pattern was not complicated, and it only took Duan Chen half a day to complete the inscription.

Then he took out the pre-prepared medicinal liquid, used the inscription needle to drop it down, and repeatedly poured it on the engraved Desolate Heavenly Demon Pattern.

When the last drop of the medicinal liquid seeped into the body of the Seven Demon Lords, the magic patterns that were originally engraved on the surface of the Seven Demon Lords' bodies immediately burst into a dark purple magic light, illuminating the entire sky.

However, Duan Chen was not surprised by this.

Engraved Devil Pattern is only the first step, and it will take a process to completely merge the Engraved Devil Pattern and flesh and blood into one.

This process is called the Evoking Pattern, and as the name suggests, it means to awaken the Demon Pattern.

Only when the invocation is successful, the entire inscription process is considered successful, and the more intense the reaction when the invocation is invoking, the higher the level of the awakened magic pattern.

Generally speaking, only the highest-level magic patterns can glow with dark purple magic light when summoning patterns, while normal magic patterns, such as the black moon magic pattern, are generally black when they are called.

From this point of view, the Seven Demon Lords were not lying, this Ancient Heavenly Demon Pattern was indeed one of the highest-level Demon Patterns.

Time flies.

The entire process lasted for a full day, and the Desolate Heavenly Demon Pattern engraved on the surface of the Blood Demon True Monarch's body gradually faded away until it was integrated into his flesh and disappeared.

And the Blood Demon True Monarch's originally evil face also had an extra demonic intent that soared into the sky, and it looked like the same as the pure-blood demon clan.

This surprised Duan Chen.

After all, the Blood Demon True Monarch was from the human race, and just by inscribed the Demon Pattern, the breath in his body had undergone such a big change, which showed that the Ancient Heavenly Demon Pattern was indeed worthy of its name.

This made him look forward to the Demon Dao Body that was about to be born.

As for the remaining task, it is to perform the Soul Splitting Technique, to divide the demon thoughts and demon babies in the body, and move them into the body of the Blood Demon True Monarch.

This is the most critical step.

Even though Duan Chen had rehearsed this process dozens or hundreds of times in his mind, he was still a little nervous in his heart.

But nervousness is nervousness, and now it is impossible for him to retreat.

After all, whether it was for the sake of saving his life in the future, or in order to be able to continue to cultivate the Demon Immortal One Thought Method, he had to successfully refine the Demon Dao Body this time.

Thinking of this, Duan Chen couldn't help but take a deep breath, and revisited the complete process of differentiating the demon thoughts and the demon baby in his mind, and began to chant words in his mouth with a pinching of his hands.

After about thirty-three breaths like this, Duan Chen, who was originally sitting motionless on the altar of time and space, suddenly flashed with magic light on his heavenly spirit cover, followed by a purple light haunting the demon baby suddenly flew out of it.

It was the demon baby that Duan Chen condensed after breaking through to the Yuan Infant Stage.
