The red-haired wolf's heartbeat suddenly stopped. However, Gu Yun did not want to perform chest compressions and artificial respiration on the little wolf, and planned to use another more effective method to save the little guy.

That's it – cardioversion!

And what is cardioversion?

Cardiac cardioversion, also known as defibrillation, is the most effective way to rescue fatal tachyarrhythmias.

To put it bluntly, when a person is dying or in cardiac arrest, the doctor uses that iron-like thing to shock the patient's chest, which is performing cardioversion.

The device with something like an iron attached to it is called a defibrillator. The principle is to use a strong pulse current through the heart to eliminate arrhythmias, cardiac arrest, etc., so that it can restore sinus rhythm.

Although Gu Yun did not have this heart defibrillator by his side. But no problem, Gu Yun has electricity!

Because Gu Yun has electricity, use electricity to perform cardiac electrotherapy on the red-haired wolf or something, that's a matter of sprinkling water~~

I saw Gu Yun stretch out two claws. The electrical energy in the body is then released.

At the beginning, Gu Yun didn't dare to open it directly. So I added it little by little. Then, two paws were placed on the chest of the red-haired wolf. As soon as the electric current stimulated, the red-haired wolf's heart and entire body trembled.

But he only jumped once, and then he didn't continue to jump.

So Gu Yun increased it again, and then came at the little wolf's chest. But as before, it didn't work.

Seeing this, Gu Yun frowned. Directly from the double dose just now, an obvious electric current could already be seen, and it pressed down on the chest of the red-haired little wolf.

It's just three things, if it's useless this time, Gu Yun won't care about him. And Gu Yun's current this time, if it is for human beings. That would definitely electrocute people directly. But what about Warcraft......

This time it really worked.

This time, the red wolf's heart was back beating.

I saw him and coughed a few times. Then spit out several sips of water.

Seeing this, Gu Yun directly grabbed his tail and picked him up. Fell on a few shakes. The red-haired little wolf was touched by Gu Yun like this, and suddenly spit out several mouthfuls of water.

But the belly has become significantly smaller. It seems to be quite effective, and the water in my stomach is almost poured out.

Gu Yun put the red-haired wolf on the ground again.

Although the heart has returned to beating. I vomited water in my stomach.

But the little guy was still fainting and showed no signs of waking up.

Gu Yun looked at the little guy, stretched out his claws and scratched his chin.

Or...... While he is still awake, sign a master-servant contract with him directly...... But Gu Yun was still a little hesitant, wouldn't it be too despicable to take advantage of people's danger like this......

But soon, Gu Yun decided, sign it! Anyway, in the world of Warcraft, the weak have no right to speak.

He is better than him, and it is his honor to be willing to accept him as his younger brother. He can't refuse, and he's not qualified to refuse.

However, it is really not good to sign here...... Let's take him back to the cave first......

Thinking like this, Gu Yun stretched out his tail. Scoop up this little guy. Put it on your back and walk towards the cave.

----------------------------------------------------------------------------------

After arriving at the cave, Gu Yun pulled a small piece from the extra part of his cloud cotton grass mattress. It's not big, it's only two meters long, about the same as a little wolf.

Then put the red-haired wolf on top of the small piece of cloud cotton grass.

Then, it's time to sign the master-servant contract.

Because the red-haired wolf passively accepted the contract, Gu Yun had to sign the contract in a tougher way.

Unlike the heart contract that Sophia signed with Gu Yun at the beginning, there is no contract.

Just the use of spiritual power, Gu Yun wanted to forcibly break his spiritual imprint into the sea of consciousness of the red-haired little wolf, and he wanted to integrate part of the little wolf's spirit into a drop of his own blood, and then integrate it into Gu Yun's body, forming a blood-colored spiritual imprint representing the little wolf, which existed in Gu Yun's sea of consciousness. At this point, the contract was established. Gu Yun can decide the life and death of the red-haired wolf through this spiritual imprint.

However, Gu Yun's temperament is still very peaceful, and as a former human being. As long as it is not a serious matter, he will not choose to use such an inhumane practice. Although he is no longer human......

Of course, under normal circumstances, the wolf cub will be in pain. But he's passed out now. Even if the pain was so painful that his body kept twitching, he couldn't feel it.

This is the master-servant contract between Warcraft, simple and rough. The strong can decide the life and death of the weak. If the contracted party is strong enough in the future. The spiritual power has also surpassed that of the contractor. That can also unilaterally break the contract, and even in the most powerful cases, it can counter-control the contractor.

Of course, as Gu Yun's younger brother in the future, he would never be able to do this.

After signing the contract. Gu Yun relied on the induction of the contract. I also know the current state of the red-haired wolf, who is still in a deep coma. I'm afraid I won't be awake until I sleep until night.

Then Gu Yun didn't care about him. Anyway, the master-servant contract has already been made. Even if he woke up early and wanted to escape, he wouldn't be able to escape.

Because as soon as he woke up, Gu Yun could feel it, and then rushed back.

So Gu Yun threw the red-haired wolf in the cave. Then I went out and dug the soil myself.

Gu Yun plans to pave all the ground of this cave with soil during the day. At night, it's time to go out and look for all sorts of glowing plants to come back and fill the cave.

Gu Yun came out of the cave directly, but he didn't go far, because he was just digging the soil.

By the way, Gu Yun also caught a zero-order demon sheep when he went back in the evening.

This was not eaten by Gu Yun himself, after all, after tasting the meat of the Rank Rank Demonic Beasts, Gu Yun was not interested in these Rank Zero Demonic Beasts at all.

This sheep was a gift he prepared for his little brother.

After Gu Yun returned to the cave with the sheep, he saw where the red-haired wolf was still lying the same as when he came back a few times before.

Gu Yun smiled and put the demon sheep beside the red-haired little wolf. Then he walked to his cloud cotton grass and lay on his stomach, and through the spiritual imprint, he said to the little wolf who was still resting over there:

"Still not up?"

But the little wolf remained motionless.

Seeing this, Gu Yun smiled, "Why do you think I brought the food back to the cave? Don't pretend, I signed a master-servant contract with you, I don't know if you faint or not?"

After Gu Yun finished speaking, the red-haired little wolf also knew that he couldn't pretend to be able to do it. He opened his eyes and raised his head to look at Gu Yun.

Gu Yun saw him looking up at him, so he asked him:

"What's your name?"
