Zhang Changlong was originally glaring at Li Tianbei, but after hearing this, his expression changed instantly.
Because what Li Tianbei said really makes sense.
Zhang Changlong is the only one who knows the spell.
In other words, he was the only one who could come in.
But with his strength, not to mention that the second level of the Earth, Fire, Wind and Water Formation is difficult to pass, I am afraid that the first level, the Mirage Oil Lamp, can directly take his life.
So Li Tianbei was right.
Speaking of which, Zhang Changlong's younger brother Zhang Changhu launched a coup, seized the throne, and occupied the Hehuang Flag, which prevented Zhang Changlong from entering the mausoleum and indirectly saved him.
If not for this, Zhang Changlong would have been unable to hold back and entered the tomb more than 100 million years ago.
"Interesting, there's something inside this cave."
Suddenly, Dongfang Bai pointed at the passage in front of them.
It was still pitch black.
But this time, there was no oil lamp inside.
Chen Xuan directly activated the Disk of Samsara to protect everyone, and did not let Zhang Changlong explore the way again, because he found that this guy's River Emperor bloodline was useless.
whoosh whoosh whoosh!
As soon as they entered the cave, countless sharp black arrows shot towards them.
Each arrow is coated with a special black liquid, which is highly poisonous.
Once shot, even a powerful Divine Emperor would be seriously injured. If he did not receive timely treatment, the wound would fester and would be difficult to heal.
It is even very likely that this will lead to one’s downfall!
Of course, all these arrows hit the Disk of Samsara, and there was no reaction at all. The Disk of Samsara shook slightly, and all the arrows were directly turned into powder.
There are also various mechanisms in this passage that are enough to hinder the progress of the powerful Divine Emperor.
But it’s useless. In front of the Disk of Samsara, all the mechanisms are not worth mentioning!
"Um, there's a blue mural?"
Chen Xuan used the law of fire to illuminate the entire passage.
He suddenly raised his eyebrows and saw that the walls on both sides were densely covered with murals.
"Why are all these murals blue?"
Chen Xuan was confused. He saw that the mural was all blue, and there were all kinds of blue-skinned monsters and little blue men, who were cheering and jumping for joy, as if they were celebrating something.
The passage was very long and there were many murals. Chen Xuan looked all the way and saw hundreds of murals.
But the embarrassing thing is, he didn't understand.
Li Tianbei, Zhang Changlong, Lin Xi, and Concubine Shu were all confused and bewildered.
"Dongfang, can you understand what this mural is trying to express?"
Chen Xuan discovered that Dongfang Bai had been looking solemn since he saw the first mural.
After looking at hundreds of murals along the way, a layer of gloom covered his face.
This shows that this guy understood the mural!
"This mural records four eras!"
Dongfang Bai's face was solemn. "I never thought that I would gain such a reward from this trip!"
Ever since he met Dongfang Bai, Chen Xuan had the impression that he was always calm and composed.
At any time, he always keeps aloof from everything that does not concern him. Apart from being a little interested in the Wheel of Samsara, he seems indifferent to anything else.
I didn't expect that now, Chen Xuan could see his other gloomy side.
"Four eras? What four eras?"
Chen Xuan spoke in surprise.
Because those hundreds of murals, to put it bluntly, look like a bunch of ghost paintings.
Chen Xuan didn’t know whether it was because he was too weak to understand it, or if this thing was just abstract?
In short, he just couldn't understand it.
However, he did imprint all these murals in his mind.
After all, just because you don’t understand it now doesn’t mean you won’t understand it in the future.
Dongfang Bai looked at Chen Xuan deeply, his face solemn as he said, "With your strength, it's no good knowing too many things. Once your realm is elevated, you'll naturally understand those things you didn't understand before."
Good man, it looks like he doesn’t want to say it!
"I won't ask you about anything else, but just now, what did you mean by the four eras you mentioned? You don't have to tell me anything else, but you have to tell me this."
Chen Xuan frowned and said.
Dongfang Bai paused, and after a moment of silence, he said, "Tell me how much you know about the times. If you know enough, I can tell you.
But if you know too little, even if I tell you, you won’t understand, so there’s no need to tell you.”
Chen Xuan's expression froze. He had a strong feeling that Dongfang Bai must have discovered something extraordinary.
After a moment's silence, he slowly said, "I know there was a mythical era, a barbaric era, and after the barbaric era, look at the new era that others are in now."
"Each era is based on the weakening period of the Abyss, and the Abyss falls into a weakening period every 2.296 billion years."
"In other words, the Mythological Age and the Savage Age have already lasted for two periods of 1.296 billion years!"
"And our current era has already passed nearly 700 million years, and there are still nearly 500 to 600 million years until this era ends."
Every word Chen Xuan spoke was sonorous and powerful. He looked directly into Dongfang Bai's eyes, and his meaning was very clear: I will tell you everything I know.
And you'd better not hide anything and tell me everything you know!
On the side, Li Tianbei and Zhang Changlong were both confused when they heard it.
What wild era?
Then another mythological era comes?
What's modern? It's been billions of years.
Why are these people talking so scary?
Anyway, they felt like they were listening to a foreign language and had no idea what was going on.
Neither of them understood, and Lin Xi and Shu Fei were naturally even more confused.
As for Dongfang Bai, he showed a look of surprise.
He knew that Chen Xuan knew something about the times, but he probably didn't know too much.
Especially Tianyuan, there is an era that is 1.296 billion years. Only a very small number of giants standing at the top of the world know this.
And Chen Xuan actually knew it.
This shows that he is really extraordinary.
"Who told you all this?"
Dongfang Bai asked.
"Of course my eldest and second brothers told me."
Chen Xuan blurted out, thinking of the King of Fengdu and Ksitigarbha Bodhisattva, and suddenly missed these two people a little.
Because if it were these two people, basically no matter what Chen Xuan asked, these two people would tell him without reservation.
Unlike Dongfang Bai, who talked a lot and kept asking questions, but never answered Chen Xuan's direct questions.
