"It's not so much an ancient city as it is a temple."

Professor Qin used to teach the Mayan history as if he was giving a class to the students, but the two 'students', Fu Qing and Wu Rong, didn't cooperate very well. This made Professor Qin less talkative, and after talking about Tong Fuyuan, he was inexplicably absent-minded. In the end, he simply skipped the history and only briefly talked about some things in the past.

"After researching, Tong Fuyuan believed that it was not a simple ancient city, but a temple left by the Mayans to worship feathered snakes. This research direction conflicted with his mentor, and Tong Fuyuan's project was ultimately rejected. Later, I heard that he organized a team to go to the Sonoran Desert in private, but encountered a black sandstorm that is rare in a century, and most of the people were folded in the desert, and he was lying in the hospital for more than three months."

Professor Qin shook his head: "Then he returns to China, and there will be no other contact between us."

"Why is Tong Fuyuan looking for the lost ancient Mayan city?"

Something flashed across Wu Rong's mind, but he didn't have time to grasp it. His expression was slightly solemn: "Does Feathered Serpent God really exist?"

The stone slab for the sacrifice, the source of the Great Tiankeng, and the endless cycle of sacrifices and offerings made Wu Rong couldn't help but think in that direction.

The so-called gods, do they really exist?

"Of course it doesn't exist."

Professor Qin glanced at Wu Rong with a subtle expression of "Why do you think so?": "Tong Fu went to find the ancient Mayan city, of course to become stronger."

At the beginning, Professor Qin specialized in ancient sacrifices and the Great Tiankeng, and also dabbled in the direction of the origin of supernatural resuscitation. At that time, he was studying at the first university in the United States, and his tutor was Professor Kelly Lang, who is famous all over the world. For such a long time, there have been several schools of thought and relatively systematic hypotheses and speculations about the causes of the spiritual recovery and the formation of the seven tiankengs.

"Some scholars believe that this is a disaster caused by the reversal of the magnetic poles and the dissimilation of the magnetic field. It is the mutation caused by human's wanton activities on the earth for thousands of years."

Qin Qing said: "Some people also think that this is an evolution of human beings."

After the supernatural recovery, all kinds of capable people emerged from human beings. Similarly, after people die and become ghosts, they can also become stronger and stronger. Humans evolved in both directions of life and death, just like the first batch of marine creatures that climbed onto land, they will eventually evolve into different species.

"They called the seven tiankengs evolution pits, energy pits."

In their view, the emergence of the seven tiankengs is a new possibility for human evolution. Some extremists advocate the survival of the fittest and survival of the fittest. They believe that the future of human beings should be the coexistence of strong humans and strong ghosts. Those who are not suitable for this world will be eliminated in the end, or become slaves of the strong.

So now everyone sees that the nine heroes sacrificed to seal the Great Tiankeng and save the world. But in the eyes of that small group of people, they are the sinners who blocked the path of human evolution.

Therefore, the think tanks headed by Professor Qin Zhennan who planned the route to the Tiankeng for the heroes hid their true identities and kept them absolutely secret, precisely because some people opposed the sealing of the Tiankeng. In that disorderly and chaotic situation, all accidents are possible.

Later, when the seven tiankengs were sealed and the world stabilized. This matter was exposed again. Most of the leaders of this group went to court and were sentenced to death for crimes against humanity. The rest were beaten like street rats, and most of them were under the supervision of the federal governments. Live the rest of your life.

"Although their claims are extreme, they do have some truth."

Professor Qin said objectively: "After the seven tiankengs were sealed, the strong men of the older generation died one after another, and the strong men of the human and ghost domains are all far behind."

Just like the current Grandmaster Lingyun can be regarded as the strongest among the younger generation of Longhushan Tianshi, and he is the leader who does his part. But at that time, each of the seven sons of Longhushan was as strong as him, not counting the celestial masters of the Maoshan sect and other sects. This is the case with the heavenly masters, and so is the case with Buddhism.

Master Kuchan, who was still immature back then, is now very old, but a monk who can take over his mantle has not yet appeared. Up to now, he has only accepted one apprentice, Huixin.

"Tong Fuyuan told me in private that he believes that the evolution of human beings cannot be terminated, and that the seal of the seven tiankengs will be released sooner or later."

Professor Qin said: "Ghosts can become stronger by devouring their own race and killing each other, but humans have already begun to enjoy false comfort. This kind of complacency will only harm themselves in the end."
