There are at least one million green soul bones here, and there are more than ten thousand wooden frames. On each wooden frame, there are densely packed green soul bones. On each wooden frame, at least a hundred green soul bones are placed.

It is not easy for Yuan Zhi of the divine beast level to grow to maturity. With so many green soul bones, it is unknown how many human warriors the poisonous demons have killed.

Qin Ming guessed that these green soul bones were different from other beast-level source plants, and they probably only needed the blood of a large class of warriors to grow rapidly.

Because the more mature the green soul bone, the more resentment it will have.

Based on Qin Ming's understanding of Yuan Zhi, these green soul bones seemed to be alive, and the speed of maturation was certainly not the same as that of other beast-level Yuan Zhi.

"Brother, there is a door here!" Qin Xixuan said suddenly.

After she came in, she kept paying attention to her surroundings.

She is different from Xuying, Xuying is sentimental, she is most concerned about Qin Ming's safety.

So after entering the room, she has been checking to see if there is a powerful poisonous demon here, but she accidentally found a door.

Of course, it was also because the door was so conspicuous.

Qin Ming looked in the direction of Qin Xixuan's finger, and he saw a dark red door.

The door is locked and protected by a formation.

"I'll open it!" Qin Ming closed his eyes, but he didn't feel the breath of life from inside, so he came to the door and summoned You Huo.

Because it was to break open the formation silently and break open the door, so when using Youhuo, Qin Ming made Youhuo burn very vigorously.

In just a moment, the formation couldn't bear the Youhuo, so it melted a big hole and disappeared with a bang.

When You Huo touched the door, the metal door was like a paper paste, it was turned into a liquid, before it even flowed to the ground, it was burnt into gas by You Huo.

Xuying watched from the side, she thought that Qin Ming's Youhuo could only break through formations and burn Yuanzhi, but she didn't expect that even metal doors could be melted away.

"This is black gold, a hard metal used to refine beast-level weapons. Because it is so hard, it is very difficult for even a refiner to melt the metal."

"Qin Ming, you turned the black gold into gas!" After recognizing the metal on the door, Xu Ying opened her mouth wide and looked at Qin Ming in disbelief.

Black gold is not uncommon, but it is also not common. There are many places in the supreme world where this kind of black gold can be mined.

With the power of the Poison Demon family, it is not very difficult to mine some of this black gold.

Mining black gold is difficult because it is so hard.

It is even more difficult to make it into a door.

The poisonous demon family put the door made of black gold here, without the protection of the beast-level defensive formation, one can imagine how much the poisonous demon valued this place.

Perhaps the poisonous demons of the poisonous demon family would never have imagined that someone would be able to break open the door made of black gold like this!

Xuying felt that unless it was a supreme powerhouse, it would be impossible to break through the door made of black gold.

If she had known that this door was made of black gold, she would have advised Qin Ming not to try it.

Fortunately, she didn't warn her, otherwise she might be laughed at by Qin Ming.

"Qin Ming, what kind of Dao Origin Skill is You Huo? Why is it so powerful? It's the Dao Origin Skill of Fire?"

"Absolutely impossible! If it is the Dao Origin Technique of the Dao of Fire, then the Dao of Fire is definitely stronger than my Dao of Space!"

"Could it be your bloodline ability?" Xuying looked at Qin Ming strangely and asked curiously.
