On the one hand, its functionality is quite strong. Soul fog can obscure perception and distort the opponent's thinking and cognition, and its uses are very wide.

On the other hand, Jiang Chen judged that the value of the Soul Ancestor's arm should be greater than the total value of the remains of a bunch of powerful monsters and the arm of the pseudo-god-level ancient blood demon.

In short, this Yinsha leader should have great potential to be tapped.

Finally, after about half an hour, the Yinsha Commander successfully broke through. The magic on its body became more vivid, and there seemed to be many more strange magic characters. In addition, lines of soul power laws lingered around it, making it look more ancient, mysterious and difficult to guess.

The armor also changed, the edges becoming a black robe style, and the iron armor covering the face disappeared, replaced by a ball of black mist that could not be seen.

It looks a bit out of place now.

However, Jiang Chen guessed that once he broke through to the great power level, this commander would undergo a huge change, which was equivalent to growing from a low-level troop to a higher-level troop.

"Walk."

He gave a call, and Tiezhu took the two of them and disappeared at an extremely fast speed.

Soon after, they appeared in a wilderness. The ground was cracked on all sides because all the grass and trees were dead. There was no sign of life around. In the distance, there was an unfinished building complex with several brick houses. Judging from the architectural style, they were built decades ago.

This should be an area that the White Elephant Kingdom was planning to develop, but in the end it had to be stopped due to certain things.

More than three thousand meters to the left of the building complex, there is a huge sinkhole with a diameter of fifty meters. The land is charred black and is dozens of feet lower than the surrounding area. The area above the sinkhole is very strange, as if the colors have been sucked out, and the clouds appear a terrifying grayish-white.

Watching from a distance, one can't help but feel a sense of horror.

It seems that once you step into there, a part of the living person will be pulled out and no longer belong to you.

In the center of the tiankeng is a huge portal close to the ground.

It is dark black and translucent, like crystal or some special jade, more than three meters long and one and a half meters wide.

There was a strong chill coming from this door, as if it was enough to freeze the whole world.

"This is a treasure of heaven and earth. That's why Jitu is the best-preserved of the six forbidden areas." Tiezhu spoke from the side, showing off his profound knowledge. He held his head high and chest out, looking like he was pointing out the world.

Jiang Chen looked over, with a hint of surprise in his eyes.

He had seen more than one gate to a restricted area, so he could naturally tell that this one was the most unusual.

"What do you mean?" he asked.

In order not to miss any evil ghost, they chased it all the way here. Although they didn't get any other gains, they came here to take a look as they thought they were close to the Land of Silence.

Tie Zhu organized his words, "I'm sure you've heard about this, Dad. The Forbidden Zone portal has little to do with the Forbidden Zone itself. It was built by people in later generations to seek some psychological comfort."

Jiang Chen nodded. Erlang had mentioned this to him before.

"But think about it, Dad. Are those powerful people who dominated the world in every era, even Daoist masters, really so foolish as to do useless work?"

"In fact, someone once used a seal cast by someone else to intercept the existence in the restricted area."

"But this incident is like a legend or myth, only mentioned in some ancient books."

"It's said that this happened during the Glorious Era. An earthly immortal used a peerless treasure to refine a portal in an attempt to permanently seal the six forbidden areas. Although it wasn't completely successful, it did have some effect."

"The most famous one at that time was the portal to Jitu."

"A mysterious figure made a lavish effort to find a piece of Qianshi Immortal Jade. Subsequently, over ten Earth Immortals of the time worked together to refine it for nine days and nine nights, ultimately creating a supreme treasure comparable to the Book of Life!"
