"You think too much! Those Supremes will leave a soul lamp in the clan before they set off, as long as the soul is not extinguished, that soul lamp will always be on, but guess what happened? All the people who tried to reach the upper realm through the Heavenly Divine Mountain died without exception, and even their souls were wiped out!"

"Is Tongtian Divine Mountain so terrifying?"

"Of course, one of our demon ancestors came down 20,000 years ago, and at that time, the barrier between the upper and lower realms had not yet been raised, but later, even he couldn't go back, so he stayed in the lower realm. ”

"I know that the Heavenly Demon God Senior is from the Upper Realm, but has he climbed the Heavenly God Mountain?"

"Of course not, are you stupid, brother of the Heavenly Desolation? Have you forgotten who we are? That's the Divine Mountain!"

Wu Kun was a little speechless and said, "Then what do you use the example of the predecessors of the Heavenly Demon God to illustrate......?"

"At that time, the Heavenly Demon God predecessor was not injured, I studied with him for a while, and he told me a lot of secret things, 20,000 years ago, that is, when there were no barriers in the upper and lower realms, it was easy for people in the upper realm to come down, but it was difficult to go up, at that time there were two roads, one was to reach the Heavenly God Mountain. ”

"What about the other one?" Wu Kun asked impatiently.

At that time, the Tongtian Divine Mountain was a place for the human race and the demon race to go to the upper realm, and there were many tests on the way, and when those who claimed to be geniuses passed through layers of tests and came to the upper realm that they had been thinking about, they would find that there would be a group of unkind people waiting for them. ”

"And then they're all dead?"

"No! it is more terrible than death! If it is a powerful demon beast, those in the upper realm will capture them and turn them into their own mounts or take them back to guard their mountain gates, and if they are human beings, they will take them as their servants. ”

Wu Kun was shocked in his heart: "Isn't this Tongtian Divine Mountain a trap?

"Think about it, those geniuses who were once invincible in the lower realm, but when they arrived in the upper realm, they were treated like this, is it more sad than death?

Wu Kun nodded and asked, "Then what happened later?"

"Later, there was a drastic change, and the Heavenly Demon God Grandpa was also sent down after that great change, he told me that the barrier between the upper realm and the lower realm was built by all the super clans in the upper realm, but the strange thing is that the interface between the Tongtian Divine Mountain and another upper and lower realm has never been affected by the barrier, so they sent countless strong people to guard the exit of the Tongtian Divine Mountain, no matter who it is, they will all be killed!"

"There is no one guarding the other place?" Wu Kun was a little puzzled, Yin Shiyin didn't seem to have missed it, her logic was very strict.

"No, because no one can pass through that place at all, that place is in the southernmost forbidden area! I think you have also heard of the horror of the forbidden area, however, the forbidden area is just the beginning, after entering the forbidden area, you will have to spend countless hours at the entrance to carry out endless reincarnation, if you are lucky, you may be able to reach the upper realm, but all this is not over, do you know that the road connects to the place in the upper realm?"

Wu Kun shook his head and said he didn't know.

Yin Shiyin continued: "The source of the Heavenly River! And it is in the middle of the river! If you can have the terrifying thunder power that is not afraid of the Heavenly River, you can give it a try." The Heavenly Demon God senior also told me that the Heavenly River is extremely mysterious, even if a god-level powerhouse accidentally falls into the water, there is only one way to wait for him!"

Wu Kun only noticed the first sentence Yin Shiyin said, and he asked with a little surprise, "The source of the Tianhe?"

He didn't expect that the heavenly river full of divine corpses actually flowed from the upper realm to this place, so logically speaking, this place should be between the upper and lower realms.

"Then can we go all the way up the Tianhe River that we can see now, and then go to the source?"

"I don't know, I didn't ask the Heavenly Demon God Grandpa at the time, and I didn't think that there would be a day when I would go up, wouldn't it be good to stay in the Nether?"

Wu Kun didn't speak, he kept these in his heart, what he thought was that he would give it a try after he reached the destination of their trip, who knew if he could reach the upper realm?

He turned his gaze to the matter in front of him: "After so many days, have you found anything?"

"I found some strange jade boxes with a lot of black liquid, and I don't know what they do. ”

"There's such a thing? Why didn't I find it in the first place? Show it to me. ”

"That's because you're blind!"

Yin Shiyin handed one of them to Wu Kun, Wu Kun didn't find them It was not surprising, there were tens of thousands of cubic meters of space in this ring, and there were countless things in each place that attracted his attention even more, such a few jade boxes were really inconspicuous.

"Nothing strange, is it? It's just an ordinary black spirit liquid. ”

Wu Kun took out some liquid, felt it with his spiritual sense, and said, there is really nothing strange about such liquids, even in their nether realm, it is very common. The effect is also very simple, that is, it can quickly extract the essence of the treasure medicine, and it is a liquid that must be added when refining medicine.

"I thought the same way you did. Yin Shiyin said unhurriedly.

"Don't be so mysterious, I know Sister Shiyin is the smartest, tell me quickly!"

"In that case, this holy woman will remind you, do you see if the jade box is particularly extraordinary?"

Wu Kun's face was black, and he thought to himself: "Isn't this jade box ordinary, do you still want to say it......

"Think about it, don't you think it's a little strange that such a jade box, which is far more valuable than the black spirit liquid, is used to hold such an ordinary thing?"

"I said, Sister Shiyin, why is your focus different from others? Also, you haven't just studied this box these days, right......?"

"Wrong! Who said these jade boxes are worthless? Look at what's on this jade box. ”

"Isn't it just a word?"

"Then you can try to inject your spiritual power into it. ”

When Wu Kun's spiritual power was input into it, the entire jade box instantly lit up with a green light, and the liquid in those jade boxes began to tumble, gathering little by little essence above the jade box.

"Devil's axe! Devil's axe! This word is actually a rune! Can actually hide the rune seal in the word, and can engrave such a formation, it must be a strong man who can do it!"

"Stunned, right? This was discovered by this saint!"
