At this time, King Yin was lying in the corner of the living room, resting with his eyes closed.

The mutant cheetah was also lying next to the Silver King at this time. These two guys with similar body shapes seemed to have a pretty good relationship, even sleeping next to each other.

"You won't let me touch this guy, right?" Xu Xin was a little helpless.

Whether or not the Silver King should be allowed to mutate is a question that requires careful consideration.

The first thing to consider is whether the Silver King will lose his mind after mutating.

In fact, even if he loses his mind, Xu Xin can still use the mount contract to suppress it, just like the bat he used to contract with the mutated beast can still completely obey his command.

But after spending the past few days with the Silver King, and even experiencing extremely dangerous battles together, they already have a very tacit understanding. A Silver King who has his own will and can cooperate with Xu Xin is naturally better than a Silver King who just follows orders.

The Silver King is much stronger. And Xu Xin is not willing to let the Silver King lose his will. He has regarded the Silver King as a partner and does not want to turn it into a tool wolf.

Fortunately, Changyin also said that there is a high chance that Silver King will not lose his will.

However, even if he does not lose his will, there is another problem. If the Silver King becomes a mutated beast, when he faces those underground monsters in the future, will the mutated beast in his hand be replaced by a higher-level beast?

Beast influence.

Chang Yin told him that this contract was made with the blood of high-level mutant beasts, which means that high-level mutant beasts have the strength to make low-level mutant beasts surrender. If they are just frightened and unable to move, it is okay, in case they rebel...

After thinking about it, Xu Xin felt that the problem was not too big. First, he was bound by a contract, and second, he could put the mutated beast into the bracelet in advance.

Xu Xin finally decided to ask Silver King for his opinion.

He took out a bottle of mutation potion from his backpack, came to Silver King's side, and squatted down.

Seeing Xu Xin approaching, the cheetah on the side jumped to another corner and lay down, not wanting to get close to him at all.

"This guy..." Xu Xin glanced at the cheetah speechlessly.

"Ouch?" At this time, the Silver King also opened its eyes. When it saw the mutated potion in Xu Xin's hand, it let out a confused cry.

"Silver King, do you want to become as strong as that guy?" Xu Xin pointed to the cheetah lying on the side and asked Silver King softly.

Silver King's eyes lit up, and his crawling body stood up, letting out an affirmative wolf howl: "Aww!"

After bringing the cheetah back, the two big guys seemed to have had a brief spar. It was obvious that the Silver King was far inferior to the cheetah in both strength and speed, so it was naturally impossible for him to win.

As the former wolf king, he dared to face the jungle overlord, the brown bear, so he naturally had a strong heart. Now that Xu Xin said he could make him stronger, of course he would not refuse.

Xu Xin had long regarded Yin Wang as his partner. He sat next to Yin Wang and explained the pros and cons of the mutated potion.

I don’t know if Silver King’s IQ can understand what Xu Xin said. After Xu Xin finished speaking, it lowered its head and fell into deep thought. But in just ten seconds, it raised its head again and issued a message to Xu Xin.

A determined cry: "Ouch!"

Xu Xin understood that it wanted to take the mutation potion to mutate.

"Are you sure? I can't 100% guarantee that you still retain your will." Compared to Silver King, Xu Xin herself was still a little hesitant.

"Ouch--" Silver King let out a wolf howl, causing many frightened birds to fly out of the trees around the tree house. As if receiving a signal, different sounds continued to be heard in the originally quiet jungle at night.

The howl of wild beasts.

Canines repay their kindness. Xu Xin saved Silver King's life, and Silver King was naturally willing to fight with him as Xu Xin's mount. But as a former wolf king, it was also unwilling to surrender its strength to other beasts.

under.

Xu Xin understood King Yin's determination and opened the stopper of the reagent bottle in his hand. A strong smell of blood instantly rushed into his nostrils.

"If you really want to, just open your mouth."

The Silver King opened its big mouth without hesitation, and its sharp wolf teeth were so sharp that it seemed that it could tear any prey into pieces.

Xu Xin did not hesitate any longer and poured the entire bottle of mutated potion into King Silver's mouth.

Yin Wang swallowed the potion and stood there. Xu Xin also stood up and looked at Yin Wang with a serious expression, observing the changes in Yin Wang's body.

As a result, one person and the other stared at each other for a long time, but nothing happened to Silver King.

"Ouch?" Yin Wangba clicked his wolf's mouth and let out a confused cry.

Xu Xin also had a feeling of obstruction that caused the sneeze to not come out.

"What's going on? Why hasn't the Silver King changed? Could it be that the reagent doesn't take effect immediately, but subtly changes it?" Xu Xin frowned, "No, Chang Yin said before that the effect of the reagent is immediate.

"

"Huh?" Coco, who was about to fall asleep on the soft sofa, was also attracted by the smell of blood. He ran over and tilted his head when he looked at the two wolves looking at each other.

The mutated cheetah in the corner didn't react at all, probably because he was used to the smell.

After waiting for a few more minutes, there was still no change in the Silver King. Xu Xin had not said anything yet, but the Silver King was a little anxious. He seemed to think that he could not become stronger even with the medicine, and he let out a reluctant howl: "Ouch!"

"Huh?" Just when Silver King howled, Xu Xin caught a glimpse of its wolf fangs. The two sharp wolf fangs seemed to have grown longer, which reminded Xu Xin of the wolf statue on the altar.

It has two extremely sharp and huge wolf teeth, which looks extremely terrifying.

"Silver King, open your mouth!"

"Ouch?" Silver King was annoyed, but after hearing Xu Xin's words, he still opened his wolf mouth.

Sure enough, the two canines on the upper jaw became a little sharper and more protruding at this time, but the change was not very big.

"Could it be that the dosage of the reagent is not enough?"

At this time, the cheetah walked slowly from the side, raised its paw and pointed at the Silver King, and made a "wow" meow at Xu Xin.

"What do you mean?" Xu Xin was confused.

Several of his contracted beasts were like spirits, each one smarter than the other, but Xu Xin couldn't understand what they were saying!

When Coco heard the cheetah's cry, she began to bark at Xu Xin again and made gestures with her two paws.

It took Xu Xin a long time to understand, and raised his eyebrows: "Let King Yin continue to drink?"

Seeing that Xu Xin understood what she meant, the cheetah licked its paws and returned to the corner to lie down again.

The dose was really not enough! His eyes lit up, Cheetah must have said this because of his experience, which means that Silver King is probably as powerful as Cheetah!

He immediately took out another bottle of reagent and poured it into King Yin.

This time, Silver King seemed to have some reaction. His originally dark pupils turned a little red, but there was still no big change.

It wasn't until Xu Xin gave the Silver King all the six bottles of mutated potion in his hand to drink that the Silver King's reaction began to become violent. Its body was shaking uncontrollably and its teeth were clenched. Xu Xin could clearly see

Then, its eyes began to turn blood red.

Then, from what seemed to be the heart under its body, red blood lines began to spread outwards rhythmically. The rhythm seemed to be the same as the heartbeat of the Silver King. The blood-red patterns looked a bit dazzling on the Silver King's silver-gray body.

.

But gradually, the speed at which the blood-red patterns spread slowed down, and the Silver King also let out a somewhat painful cry.

"The dosage is still not enough!" Xu Xin quickly went downstairs to the mutated potion synthesis table, used an empty reagent bottle and contaminated meat to make a new mutated potion, and rushed upstairs to drink it for Silver King.

The Silver King's expression was soothing, and then the blood-red patterns suddenly spread all over its body. At the same time, the two teeth on the Silver King's upper jaw quickly grew outwards, and the fangs also had blood-red patterns, making it as powerful as a saber-toothed tiger.

The pupils turned completely blood red, and the Silver King suddenly raised his head to the sky and let out a long roar: "Ouch————"

The roar was louder than the last time, but this time no beast in the jungle dared to make a sound. There were no too bright red dots around the tree house, and the beasts around were not strong, so they did not dare to attack the Silver King at all.

Now Changxiao responds and provokes.

"Did you succeed?" Xu Xin looked at the Silver King in front of him nervously. He was a little afraid that the Silver King would lose his will.

He looked at the pair of blood-red eyes. The coldness in his eyes dissipated instantly when he looked at Xu Xin. The Silver King took two steps closer, rubbed Xu Xin with his head, and made a sound of "ouch"

Call.

"Haha! Success!" Xu Xin rubbed Silver King's big head, "Let's go down and take a walk!"

"Hey!" Coco heard Xu Xin say this and climbed directly onto his shoulder, indicating that it wanted to go down too.

The cheetah beside him also stood up.

One person and three animals were standing under the tree house at this time.

He stepped on King Yin's back: "Come on, King Yin, use your fastest speed, let's go to the salt mine!"

"Ouch--" Silver King let out a wolf howl and rushed forward quickly with Xu Xin on his back.

"Fuck!" Xu Xin was shocked by the speed of Silver King at this time. Before the mutation, Silver King ran very fast, at most about 40 kilometers per hour, and the speed at this time made him feel faster than before.

Times!

Carrying Xu Xin on his back, he can reach a speed of 80 kilometers per hour! It has reached the lowest limit of highways on earth and can go on the highway!

The fierce wind blew into Xu Xin's face, almost paralyzing him. He took out the iron helmet from his backpack and put it on, using it as a motorcycle helmet. Or should we call it, a wolf cavalry helmet?

Coco had already climbed down from Xu Xin's shoulders and firmly grasped the hair on the back of Silver King's neck, otherwise he might be thrown off directly.

A speed of eighty kilometers is nothing to the cheetah. Even if it does not mutate, it is still faster, so it is running beside the Silver King very easily at this time.

But Xu Xin knows that even if this speed is nothing to a cheetah, it can't run for long. It will be exhausted in a few minutes at most. Endurance is the biggest shortcoming of cats, but the Silver King can maintain this speed and run for a long time.

!

Not far away, a sika deer was chewing the grass on the ground.

They come out to eat grass late at night. Life is too irregular. This is not good!

"Silver King, kill that deer!"

"Ouch!" Silver King howled and flew towards the sika deer.

The sika deer was frightened by the cry of the Silver King and ran at full speed. However, its speed was too slow in front of the current Silver King. The Silver King directly chased after it and bit the sika deer on the neck.

As Xu Xin watched, the two fangs directly penetrated the sika deer's neck. The Silver King Wolf closed its mouth and bit the bone instantly, and the entire deer head was directly separated from the body!

Silver King shook his head and threw the deer head in his mouth to the ground.
Chapter completed!
