The Ancient God Emperor Gai Xuan's worries were reasonable, he witnessed the theft of the 72-story tower with his own eyes, and saw that the passage of the God Realm was briefly opened, and there was an indescribable unknown force pouring into it, anyone would suspect that immortal in the God Realm, anyway, Zhang Ruochen had also seen the Eternal True Ruler make a move, although his providence was not annoying, but it was not strong to that extent.
And let's not forget, Gai Zhen also had been in the Eternal Heaven Kingdom for a period of time, although he did not enter the core camp, but he also more or less understood some of the methods of the Eternal True Zai, which was easy to identify, not to mention that at that time, the Eternal True Zai went to the Dark Abyss to fight the Hongmeng Black Dragon, and it was unlikely that he would come over, so he hurriedly ran away to prevent being killed by the immortal in the God Realm.
If this is the case, we have reason to suspect that the immortal space-time ancestor of the god realm has returned from time and space, and he is sitting in the god realm, before Zhang Ruochen flickered the void to go to the god realm to deal with the Nine Dead Alien Emperors and rescue the Heavenly Demons, the Space-Time Ancestor was not there, and when the Immortal Ancestor sent the Nine Dead Alien Emperor, it was not to send him to death, so the Immortal Ancestor was the first to get this news.
Eternal Zhenzai once said to Zhang Ruochen that the ancestor of time and space is not in the current time and space, and it is very likely that he was injured in the battle of that year, such as the great emperor of Fudo Ming who hid in the long river of time and space to cultivate, with the time and space ancestor of the way of time and space, he can even peek into the past and the future.
Looking at the Ancestor of Destiny, it is not difficult to find that when he was on the Great Wall of Beize, if he was not stopped by the Ancestor of the Underworld, he would even be able to come across the long river of time, and the cultivation of the Ancestor of the Destiny was not as good as the Ancestor of the Immortal, and he almost completed this feat, not to mention the Ancestor of Time and Space.
There is also the Immortal Ancestor, she was injured by the Immovable Ming King Dazun across the long river of time and disappeared for a long time, but the Immovable Ming King Dazun calculated at which point the Immortal Ancestor would come, and sent the Reverse God Tianzun to intercept it, so that the Immortal Ancestor was injured and injured, and the situation of the Time and Space Human Ancestor may be similar, he came from the past time and space to the present.
But the layout of the Ancestor of Time and Space is more clever than that of the Ancestor of the Underworld, because he can see the future in the past time and space, and he can calmly arrange it to pave the way for his future self, to put it bluntly, he is like us watching a video, and he sees the situation of the entire universe, so he can make a move at a critical moment and steal the 72-story tower.
If that's the case, the injuries of the Time and Space Ancestor are still not healed, he can only sacrifice the 72-story tower to trap the Immortal Ancestor, let the King of Jizo blow up the divine source, and he himself needs to continue to hide, he also knows that his identity can't be hidden for too long, so he let the Eternal True Zai build altars everywhere to divert everyone's attention and provide enough energy for himself.
Looking at it this way, now the divine realm is the tiger's den in Longtan, and whoever goes will die. But if you think that the time and space human ancestor only has these methods, then it is a big mistake, because he has already seen that the ancestor will fall in this battle, then he must know the people who participated in the war at that time, and he doesn't know Zhang Ruochen's true identity.
Moreover, the Space-Time Human Ancestor spied into the future, knowing that someone had saved the Heavenly Demon, but still let it go, there were only two possibilities, one was that he had a way to deal with these people, and the other was that as long as the strength of the Space-Time Human Ancestor recovered, he would not be afraid of anyone. The latter scenario is more likely, otherwise he would not have put so much effort into building the altar.
