The counterattack system is only available in the Mahayana period

Professor Feng was as unconscious as Alzheimer's disease. He squatted on the ground, spread his arms, and flapped up and down, like a bird.

Xia Chao and Qiushi hurriedly dialed the phone, trying to call an ambulance.

The ambulance arrived slowly, so Jiang Li directly picked up Professor Feng and took him to the largest hospital nearby.

The medical staff had seen many situations similar to Professor Feng's, and they skillfully carried him to a stretcher and sent him to the emergency room.

"Why is the patient this time only in his fifties?"

"Who says it's not the case? I've read on the Internet that the age of patients has been declining recently. We're not special, it's the same across the country."

Two nurses followed the doctor into the emergency room while talking in low voices.

"In your world, this kind of situation is very common?" Jiang Li discovered that there were many symptoms similar to Professor Feng's in the hospital.

The patients talk nonsense in a way that makes it impossible to understand what they are trying to say.

At first he noticed this with his spiritual consciousness, but he didn't take it to heart. He thought that Alzheimer's disease in this world generally starts early.

Now it seems that this is not the case at all.

Xia Chao nodded: "Well, we call this assimilation disease. It is a symptom that has existed since the birth of the beast master system."

"The contracted beast is not very intelligent and its brain is chaotic. We cannot understand the meaning of the contracted beast's language. After signing the contract, the contracted beast will affect the beastmaster's brain all the time."

"There is almost no impact when you sign the contract at the beginning, but as time goes by, the impact will gradually become greater, as if there is another voice in your head, constantly saying words of unknown meaning."

"In the end, the beast master's mind will be completely occupied by another voice, and he will eventually go crazy."

"The instructor has always emphasized the need to be friendly to the contracted beasts, treat the contracted beasts as friends, and try to understand the meaning of the contracted beasts' language, because doing so can delay the onset of assimilation disease."

"Professor Feng's condition has reached the advanced stage of assimilation disease. If he comes back a few more times, he may really go crazy." Qiushi was worried, and the joy of just learning to cultivate immortality was gone.

Professor Feng is a very good teacher. Although he is serious, he always brings some short stories when giving lectures. The class atmosphere is lively and he doesn't leave much homework.

"Professor Feng has been reminiscing about the past recently. I thought he was thinking about the glory of the past, but I didn't expect that he just wanted to sort out his memories before going crazy."

The two of them had long discovered Professor Feng's anomaly, but neither of them took it to heart.

After all, Professor Feng is only in his fifties and is not yet the age where assimilation disease occurs.

"Now it seems that the onset of assimilation disease is advancing earlier." The two also heard the conversation between the nurses.

"I remember Professor Feng specifically talked about the age of onset of assimilation disease. Two thousand years ago, even if you lived to be 120 years old, you would not get the disease."

"Later, as the beast master system continued to improve, while we gained the power to fight monsters, the onset of assimilation disease gradually advanced, from one hundred and ten years old, to one hundred years old, to ninety years old... and now to more than fifty years old. age."

Everyone is destined to suffer from assimilation disease, but some people get it early and some get it later. Generally speaking, the age of onset of assimilation disease is earlier.

And Lingxi World has not found a good solution.

Jiang Li frowned, this was no small problem. He no longer blindly studies the effects of the master-servant contract.

"You guys wait here for a while, I'll call an expert."

Xia Chao and Qiu Shi look at each other, experts? There are many experts on assimilation diseases in this hospital, and even experts on assimilation diseases in the capital come here to discuss and study.

Where can Brother Jiang find experts?

Jiang Li disappeared directly from the eyes of the two people, and Qiushi was shocked.

"Don't worry, it's normal operation." Xia Chao looked calm. He had been flown to space by Jiang Li and was a person who had seen the world. Now even if Jiang Li crushes the planet, he will not be surprised.

"What on earth did you summon?" Qiushi can guarantee that Brother Jiang is definitely not from their world.

"immortal."

…

"Old Bai, where is the elder of your Dao Sect who knows the way of contract? I have something to do with him." Originally, Jiang Li wanted to study the master-servant contract slowly and leisurely, but now that something like this has happened, he can no longer play with it.

The way of contract is a very unpopular way of cultivation in Kyushu and is almost extinct. Only the Dao Sect still has its inheritance.

Nowadays, the way of contract has been revived in Kyushu, and Lingbao contracts can be seen everywhere in Kyushu.

The blueprint for the Lingbao Contract came from Dao Zong, an elder who was good at contracting.

"Are you looking for Elder Tang Xing? He's on that hilltop." Bai Hongtu pointed to a place, and Jiang Li turned around and left.

"Is Elder Tang Xing here?"

Hearing the voice of the Human Emperor, Elder Tang Xing hurriedly came out to greet him.

With the promotion of the Lingbao Contract, Elder Tang Xing's status in Kyushu has increased, and his salary has been several levels higher than before.

And all of this is due to the dichotomy of Lingbao proposed by Jiang Li at that time, that is, Lingbao is bound by law in the Great Zhou Dynasty, and Lingbao is bound by contract in places outside the Great Zhou Dynasty.

Jiang Li also found the Brahma Tower and asked the Brahma Tower to temporarily build a space channel to teleport Elder Tang Xing over.

On the way, Jiang Li briefly talked about the master-servant contract. Elder Tang Xing was cautious and did not express an opinion, saying that he would have to see the real thing before he could make a conclusion.

Professor Feng was still in the emergency room. Jiang Li and Elder Tang Xing disappeared and entered the emergency room.

"It's the most troublesome soul contract."

"Let me see the effect of the contract. The contract can only be established if both parties to the contract are willing."

"The contract between master and servant, one party is the master and the other party is the servant. The servant must help the master absorb spiritual energy from the air and feed it back to the master."

"A servant cannot surpass his master in cultivation."

"A servant must obey all his master's orders."

"Well, if the servant cannot understand the master, he will be forced to understand the master's meaning."

"The master-servant contract is rooted deep in the soul and is passed down by blood. The more people the servant's ancestors sign the contract with, the more servile the servant will be, and the sooner he will be forced to understand the master's meaning."

"It seems that this is the problem. Monsters can only open their spiritual intelligence when they reach the stage of becoming gods. Before that, they can only speak simple monster language. Understanding monster language is too difficult for humans who have not practiced it, which will lead to the spiritual platform Assimilation, collapse.”

"In order to resist the attacks of monsters, everyone in the Lingxi world is a beast master, and their ancestors are all beast masters. Over time, the master-servant contract will become more and more mandatory, and the age of onset of assimilation disease will also advance. .”

"In another thousand years, you will get assimilation disease in your twenties and thirties, and by then the entire human race will be finished."

Jiang Li roughly guessed what the slow death poison that the extraterrestrial devil had given to the Lingxi world was.

It's this master-servant contract.

"Can I terminate the master-servant contract?" Jiang Li knew that he could terminate the contract with Xia Chao, but he was not sure if he could terminate the contract with others.

"The master-servant contract involves the soul, so it is logically difficult. But after all, the Emperor is in the Mahayana stage. It is not difficult for the Emperor to terminate the master-servant contract. There is a 90% chance of success."

"However, if the Human Emperor wants to terminate the master-servant contract around the world, there is a 10% chance of failure, and the result of failure is death."

"In other words, 10% of people will die from breaking the contract?"

"yes."
