The counterattack system is only available in the Mahayana period

The first thing that comes to mind is the contract that Xia Chao and Qiushi are very familiar with - the master-servant contract.

It's just that the usage of the master-servant contract on the mural is very different from the current Lingxi world.

Xia Chao saw the powerful contract beast on the mural surrendering at the feet of the human race and being loyal to the human race. The annotation on the side showed that this was a master-servant contract, and the mark held by the human race symbolized the master's intention.

"When the master-servant contract was first used, humans were the masters and the contracted beasts were the slaves. It is the opposite from now."

Xiaoqing and Bone Wing White Tiger were angry and dissatisfied with the previous era.

Why should humans be their masters?

Xia Chao ignored Xiao Qing, who was hanging on his neck and rolling his eyes, and continued to try to decipher the content of the mural.

The murals don't seem to record something as a souvenir. Instead, they seem to go crazy and crazy in despair, trying to record everything and leave their own traces in the world.

Therefore neither the frescoes nor the annotations are easily identifiable.

It's hard to imagine what happened to push a monk who was at least in the late stage of divine transformation into a desperate situation.

"Although they have signed a master-servant contract, the human race does not treat the contracted beasts as slaves and call them here and there at will. Instead, they treat the contracted beasts as friends and give them equal status."

"Contract beasts help humans practice, so some humans start to study the laws of various things in their spare time, summarize the laws, and use spiritual energy as a driving method."

"This method greatly promotes production and facilitates humans and contracted beasts."

"More and more contracted beasts like the human race's technology and voluntarily sign contracts to become slaves and serve the human race."

"Humans and contracted beasts develop harmoniously, and both sides become stronger and stronger."

"One day, a strange monster appeared. It had a snake-like body and nine heads. No one dared to sign a contract with the strange monster."

"A man named 'Ba' signed a contract with this monster."

"The nine-headed contracted beast cultivates very quickly. Due to the effect of the master-servant contract, the slave's cultivation level cannot surpass the master. 'Ba''s cultivation is always one level higher than the nine-headed contracted beast."

"When the nine-headed contracted beast reaches the stage of becoming a god, it opens its spiritual wisdom, inherits the memories of its ancestors in its bloodline, and finally understands its own life experience."

"The contracted beast with nine heads is named Xiangliu. It is a species of fairy beast. It has an atavistic phenomenon. The purity of its bloodline is highly consistent with its ancestors. This is why it cultivates so fast."

"Later, after continuous battles and killings, Xiang Liu became the period of transcending tribulation, and 'Ba' also became the period of transcending tribulation."

"At this time, people realized that above the integration stage is the tribulation stage."

"After that, Xiang Liu will become an immortal, and 'Ba' will also become an immortal."

In the mural, Xiang Liu, who is taller than the mountain, stretches out his nine heads to fight against the catastrophe of becoming an immortal. "Ba" stands next to Xiang Liu, asking Xiang Liu to stop the catastrophe of becoming an immortal for him.

The ladder to immortality appears, and Xiang Liu and "Ba" become immortals.

"This is both the first and the last person to ascend in the Lingxi world. Whenever someone asks how to become the Tribulation Stage, 'Ba' and Xiang Liu are worried that someone will surpass them, so they keep silent about it."

"No one in Lingxi World has ever become an immortal."

Seeing this, Jiang Li shook his head slightly, "Ba" and Xiang Liu openly said that becoming the Tribulation Stage was the one who harmed the Lingxi world.

It's a pity that people in the Lingxi world didn't understand what it meant, and thought "Ba" and Xiang Liu were unwilling to share their experiences.

"After one person and one beast ascended, they never came back. Perhaps they ascended to the fairy world and could not come back down."

After Xia Chao read the notes on the mural, he turned to ask Jiang Li.

"is that so?"

"Of course not. As long as there is a ladder to immortality, an immortal can go to any world from the immortal world, including the world he ascended to."

"Then why haven't they come back?" Qiushi was puzzled.

"Because 'Ba' has never practiced, it is equivalent to becoming an immortal while lying down. Although he has reached the immortal level, in terms of actual combat ability, he is far inferior to the same level. The immortal world is not a place where harmony and wealth can be made. After he ascends, he may Died in the battle. Due to the existence of the master-servant contract, when the master dies, Xiang Liu will also die."

"But these are just guesses and may not be accurate."

"Although 'Ba' and Xiang Liu did not come back, they left a rich legacy before their ascension. The world of Lingxi experienced a spurt of development. The number of contract beasts and monks continued to increase during the integration period. Various bounty competitions, world competitions, and league competitions were held. , both humans and contracted beasts are keen to participate in competitions to gain fame and wealth.”

On the mural, people and contract beasts are holding hands, with happy smiles on both sides.

"Everything was going in a good direction, but suddenly one day, a contracted beast became the Tribulation Stage, but its owner did not."

"I don't know what method this contracted beast used to break the contract and escape control."

"This contracted beast seems to hate both humans and monsters. It has a violent temper and has killed countless people."

"Humans and monsters want to resist, but unfortunately they have no power to fight back when facing the second Tribulation Stage."

On the mural, a monkey with a red head and white feet grins and looks ugly. At first glance, it looks like a ferocious monster.

Xia Chao and Qiu Shi have never seen this kind of monkey.

"It's Zhu Yan. Judging from the appearance of Zhu Yan on the mural, I'm afraid he's another atavist." Jiang Li and Bai Xueling both recognized him. Zhu Yan was also an immortal beast with a powerful bloodline.

Xia Chao continued to interpret the mural: "People had no choice but to hide in the air-raid shelters, hoping to block the terrifying contract beast."

"That contracted beast made humans no longer trust other contracted beasts. People abandoned the contracted beasts and hid alone in the air-raid shelters."

"The human race has built hundreds of large air-raid shelters, but every day we receive news that a certain air-raid shelter has collapsed. That contracted beast seems to be looking for something. What could it be?"

"It seems to have discovered that humans can communicate using radio, and for some unknown reason, it broke off the contact."

"We have completely lost contact with the outside world."

"That contract beast is coming..."

The fresco ends here; the monk who painted the fresco did not finish the last sentence.

Although it was not written, everyone could guess that Zhu Yan, who was in the tribulation period, broke open the door and broke into the air-raid shelter. No one was spared, including the mural author.

Although the author of the mural is in the late stage of divine transformation or even the integration stage, in front of Zhu Yan who is in the tribulation stage, there is no difference and can only be slaughtered by him.

"Gone?" Xia Chao didn't expect that the original era was destroyed by Zhu Yan.

But how Zhu Yan untied the master-servant contract, why he hated the human race, and where he is now are all unknown.

"Maybe there will be a follow-up." Jiang Li used his spiritual consciousness to scan the air-raid shelter and found something interesting.

Bai Xueling also discovered it.

The air-raid shelter is like a giant maze. Without a map, it is easy to get lost.

Under the leadership of Jiang Li, everyone came to a small room. There was a scattered corpse in the room. It was unknown whether it belonged to one person or several people.

Jiang Li picked up a diary. After two thousand years, the paper was so fragile that Jiang Li refined it a little to increase its strength and toughness.

The first page of the diary reads:

"Today I signed a master-servant contract with a little monkey with a red head and white feet."
