"Sure enough, the defense is strong, if it is the opposite Wing Demon, I am afraid that this trick will be left with a core."

This is a seventh-order spell, condensed for such a long time, plus the assistance of the Thunder Crown. Jiang Hen knew how powerful this trick was.

However, this horned devil was severely injured, but still only had one head destroyed. One can imagine how strong this guy's resistance and defense are. It really deserves to be one of the top human shields among the demons.

But death means death, and the flesh and blood of this thing is of no use.

Jiang Hen took out the heart core and cleaned the corpse directly.

If this thing is left for people to discover, it will inevitably be wrangling in the future. Sure enough, if the strength is not enough to run rampant, it is troublesome. You must abide by all kinds of rules.

Looking at the other side, the Wing Demon who was attacked was in contact with his own Fire Phoenix.

No way, although the Arcane Fire Phoenix is ??powerful, it lacks the ability to kill with one blow. Even if the sneak attack is successful, it won't be possible for a while to win by relying on its own strength.

Jiang Hen worried that continuing to fight would easily attract other people's attention. Although it is far away from other places, who knows if anyone is staring here. So Jiang Hen started, and another thunder and lightning landed in the air.

Thunder and lightning accurately hit the Wing Demon, and instantly paralyzed it severely. Then the fire phoenix stepped forward and wrapped it in flames. Before long, the entire Wing Demon was reduced to ashes in the flames.

"Not bad, two more cores, now there are five in total."

For the Purifying Light to reach the seventh level, the perfect way to advance requires ten demon cores, which Jiang Hen calculated by himself. Now there are five, but unfortunately it still fails to meet the requirements.

But don't worry, as long as one's strength is enough, in this world, the core of the seventh-order demon is not everywhere.

Jiang Hen landed, and a gust of wind blew around, blowing the rocks on the ground one after another.

"How is this a green dragon? But that's right, only this kind of green dragon likes to live in the forest." Jiang Hen looked at the emerald green body, as if it was just a sleeping green dragon.

However, after turning it over, you can find a large wound on the green dragon's abdomen, and there is still a breath of demon power remaining on it. This is what the devil left behind during the battle.

But that was not left by ordinary demons, it was left behind when Tier 8 demons passed through here.

Even with just one wound, Jiang Hen felt a sense of panic from the heart. This is an instinct to face high-level creatures, and there is no way to suppress it.

It was just a wound, and it didn't hurt the vitality, and it could exhaust the vitality of this green dragon known for its vitality.

It was obvious that after the green dragon flew to this place, it really couldn't hold on anymore before it fell down and died.

It's really hard for the mages of Thorns City to be able to monitor the location of this green dragon. Jiang Hen didn't want to contaminate the scars left by the eighth-order demons, who knows if there will be an accident.

Once this kind of thing was encountered, Jiang Hen was not sure to use the light of purification to disperse it. If one is not careful, he will fall and become a part of the devil, which can be troublesome.

At this moment, He Zi also ran over. "This is, what is this!"

Seeing this scar, He Zi's face changed drastically.

"Don't come here, this is the scar left by the eighth-order demon, your current strength is easily affected even if you are close." Jiang Hen calmed Hezi with his strength.

He Zi was horrified in his heart, and quickly left this place. "I go to other places to exercise. Be careful yourself."

Jiang Hen nodded, he was only one level away from the eighth rank, so even though he had instinctive fear in his heart, as long as it was not deliberately contaminated, it would not have any effect.

Jiang Hen set up a tent next to it as a temporary laboratory, and then cut a hole in the green dragon to avoid the wound. Then he started to study the green dragon.

Jiang Hen was already familiar with the structure of the dragon clan, so it is easy to study now. Jiang Hen is very clear about what needs to be paid attention to, and all this is being recorded quickly.

In just one day, Jiang Hen completely recorded the entire Green Dragon structure.

"No, it can't be directly constructed like this. If it is constructed directly, it will also be a green dragon." The green dragon is notoriously poor in combat power. This is among giant dragons, but this thing has strong vitality.

Jiang Hen didn't want to make a battle difference, so he thought about it, and simply used a completely arcane structure.

But in that case, you need to go back and continue to study.

"According to my calculations, in addition to the blood skin and crystal nucleus, the heart and reverse scale of the dragon are needed. Fortunately, the reverse scale is intact and the heart is not injured.

Jiang Hen took it out carefully, and then slowly rubbed away all the traces he had left.

Those wounds created for experimentation were also disguised by Jiang Hen, making them look like demons destroyed.

In this way, even if they were discovered, they would have no evidence. After finishing all this, Jiang Hen walked out. "Leaving Hezi, let's go back." Hezi ran over quickly.

He can finally leave this place. He Zi has lingering fears about the wound these days.

Just the remaining power on a scar actually made myself so scared. The eighth rank is indeed not an ordinary creature, and He Zi is more determined to improve his strength as soon as possible.

Without strength, when facing those powerful beings, he didn't even have the qualifications to be cannon fodder.

In this way, the two came quietly, and then left quietly. There was a green dragon corpse with a few missing parts, and no one would find it during the whole process.

Even if the wizard of Thorns City saw it later, at best, he would just doubt it.

Who could have imagined that someone studying a dragon corpse would actually preserve the corpse so well. If it were them, to study this kind of thing, a lot of corpses would be needed, and each one would be completely mutilated.

With the improvement of his strength, Jiang Hen found that the effects of his endless knowledge and skill construction masters were getting more and more terrifying, and he could easily do many things that were miracles in the eyes of others.

After returning to the territory all the way, Jiang Hen directly confessed, then plunged into the laboratory and continued to experiment.

This time, Jiang Hen prepared to create the second seventh-order spell, a dragon-type summoning spell in one go.
