This is the first-level monster it once defeated. As a spoil, it was kept in a doghouse.

It took it out without hesitation for life-saving intentions.

Because these crystal nuclei are no different from the stones next to it.

Therefore, these crystal cores that can sell two or a half gold coins in human stores were generously sent out by the Black Demon King.

Looking at these crystal cores, Gu Zheng seemed to have some thoughts flashed through his mind.

In this huge dark forest, isn’t it too lonely to live alone with only a lonely snake?

Because of the racial characteristics of the promotion period, no one guarded him during the evolution process. Now it’s okay in the low-level forest. If the level is higher in the future, the surrounding enemies will be surrounded by them. If you sleep for two or three months, how can you ensure your safety?

If you can accept one or two younger brothers at this time and temporarily take them as a guardian, it seems that you won’t have so many concerns, right?

Thinking of this, Gu Zheng slowly slid towards the location of these crystal nuclei, circled around the small pile of crystal nuclei, and issued an order he had just come up with to Xiaowangshu in the sea of ​​spiritual consciousness.

‘Low down your contract book by a certain level, make a simple version of the master-servant contract like this world summoner, and take it out and sign it with the black demon dog on the opposite side.’

‘In this way, when I am promoted to the second-level monster, I don’t have to worry about being swallowed by my own world.’

Xiao Wangshu refused this in his heart, but his actions were in harmony.

It dared not reiterate to Gu Zheng how high its contract is. It can only contain grievances. It transformed a contract that should have been signed with the world's most resentful human beings into tens, and transformed into a low-version of the small world master-servant contract that Gu Zheng needs now.

Looking at the contract that appeared in front of him with a white light like parchment, Gu Zheng expressed his satisfaction.

He held the piece of paper that suddenly appeared in his mouth, turned his head and turned to the place where the Black Dog was.

At the position where the contractor stamped it, he pointed it with the snake's head, stuck out his tongue at the big dog opposite, and waited for the other party to answer.

The black demon dog was confused about this kind of animal language and was not connected with each other.

It huffed and looked at the dog's head and sniffed it towards the contract book.

The impatient Gu Zheng was too lazy to continue to explain. The moment the Black Demon Dog lowered its head, it shot out like a spring. The poisonous fangs were retracted, and the sharp teeth stretched out. With a click, two small holes bit out of the wet nose of the Black Demon Dog.

The black demon dog was in pain and took a step back. He sat in the turf of the black grassland.

A drop of blood splashed out happened to be dripping on the parchment paper, where the contractor should sign.

The most amazing thing is that when this drop of black blood stained the paper, it seemed to be absorbed by the paper, and the red blood instantly disappeared without a trace.

But at the location where the contractor signed the signature, a small puppy that looked like a black demon dog appeared, as if it was involved with the leader of the huge black demon dog opposite, making the big dog on the opposite side who had already squatted in the grass forget to bark, and suddenly became dumbfounded with a slightly confused expression.

From this moment on, the contract of master and servant drafted by Xiao Wangshu was officially completed.

The Gu Zheng, who had already slid down from the dog's nose, could only move the black demon dog sitting opposite him with just one thought.

Similarly, Gu Zheng can empathize with the joys, sorrows, sorrows, and joys of the Black Dog that became his first contract beast.

‘Oh, that’s really good.’

‘Let’s try it first, Black Dog, you look at your darkness, and you will be called Xiao Hei from now on.’

‘From now on, I will be your master. Your master’s surname is Gu’s name, and you are my dog, so you will naturally be Gu Hei.’

‘I am very satisfied with the Warcraft Crystal Core you paid tribute. Master, I will absorb and evolve now. You are the leader of this area. Do you know if you know a safe place that allows me to advance safely and quietly?’

Gu Zheng just thought in his mind that as his contract beast, the leader of the Black Demon Dog could understand it.

Maybe I thought of a very good place. After waving Gu Zheng twice, this black demon dog crawled down, and was about to carry his master.

Gu Zheng was really a person who was used to being a landlord and wealthy. He climbed up the backbone of the black demon dog without hesitation and was planning to ride the mount comfortably, and saw behind his tail point, swaying and following a fat puppy with a fat breast.

Isn't this the little puppy of the Dark Dog?

Is this going to ride with King Gu?

Before Gu Zheng could figure it out, the black demon dog who had already set his identity... was afraid that his youngest son would anger the current owner like a big demon king, so he hurriedly arched his nose and pushed the little breast into the dog while the fat dog was about to climb up.

The little black dog, who had not yet evolved into a monster, felt aggrieved for a moment. Among the small puppies, he was the weakest one. He had been collectively cared for by the dog group since he was a child. When had he ever been so disliked? In his round little eyes, pitiful tears appeared at that time.

Gu Zheng, who saw the fluff control, felt a little guilty at the time. After giving a command to the Black Devil Dog that could be done in the same process, he slid his body to the position where the big dog's head was.

As a cool demon king, just give the dog's back to the cub who is still breastfeeding.

It’s only so impressive that you can sit on the dog’s head.

The Black Dog is very grateful for Gu Zheng's decision.

It no longer cares about its weirdness at this time and its mighty image erected earlier.

A snake in front and a milk dog behind, with this strange combination, traveled through the territory of most of the other first-level monsters in the Black Grassland, and came to the safe and huge doghouse belonging to the Black Magic Dog.

As its pace approached, more and more black dogs ran out of their habitats, which were basically built in half-high mounds.

As if they were greeting their leader, they shouted loudly in the direction where the leader of the black demon dog was running.

Unfortunately, after seeing the image of their patriarch, the dogs with great vision seemed to be strangled by someone, and their screams instantly broke.

Wow, wow?

It would be fine to bring this puppy, but what happened to the terrifying worm that is nearly four meters long?

This is definitely not a prey, the hissing tongue shows that this snake is alive.

Unfortunately, the leader of the Black Dog, who had never really enlightened, could not explain it. He just shook his back and shook the little breast from above, and then rushed straight to the deepest place of this tribe with Gu Zheng.

There, there is a mound like a small hillside.

There is a huge hole in the center of the mound.

When Gu Zheng entered the entrance of the cave under the leadership of the Black Dog leader, he realized that this place was a naturally formed stone cave with extremely large space.

The stone in the cave is very strange, and it actually has the effect of warm jade.

Because there are sparse air vents inside the hole, although the hole is a little dim, it is absolutely warm and comfortable.

This is indeed a good place for advancement. When Gu Zheng thrust the crystal core in his belly into the hole, the black demon dog who received Gu Zheng's instructions walked out of the cave obediently, stuck his tongue out, guarding the house for him, and doing the work that the guardian should do.

With enough wine and full of energy, it is time to raise your level up.

Thinking of this, Gu Zheng opened his bloody mouth and sent these crystal nuclei into the snake's mouth one by one, biting the crystal nuclei one by one.

A stream of abundant energy spread along Gu Zheng's stomach, tearing his muscles and bones, and the rest were heading towards the black and dirty magic crystal formed in his skull.

I don’t know how long this process has passed, but Gu Zheng is as if he has drunk too much wine, sometimes sober and sometimes confused.

When the heat all over his body subsided, a cool feeling rushed straight to his forehead. When the tiny magic crystal made a crackling sound of reshaping, Gu Zheng opened his vertical pupils that he hadn't opened for a long time.

A long-lost hissing sound also came out of Gu Zheng's throat. As he swung his stiff head a few times, his waist raised, and bang! Gu Zheng suddenly hit a star in his eyes.

What's going on?

Gu Zheng, who felt a huge pain on his head, looked at the top of his head and realized that the cave roof, which was originally quite tall for him, became narrower and shorter because of his six molts and the promotion of the monster this time.

Gu Zheng was originally only three or four meters long, but after being promoted this time, he suddenly lost half of his length.

Even if Gu Zheng stood up, his entire height reached an extension of three and a half meters.

His length exceeded six meters. According to the judgment of snakes in reality, he can be regarded as the length of a small giant python.

In addition, his originally slender body, under the double bonus of molting and promotion, suddenly became the thickness of a human forearm, making his originally slender small scales as black sesame, all turned into willow leaves.

A mutated black demon snake with black oil and shiny black magic snake has become a unique existence in this dark forest.

Gu Zheng, who discovered his gratifying change, did not care about the severe pain above his head, and slipped out of the hole that was originally the leader of the Black Devil Dog.

When Gu Zheng's snake head poked out of the cave, the leader of the Black Devil Dog, who had been crawling outside the cave for nearly a month, was the first to feel Gu Zheng's changes.

It first barked twice, suppressing the restlessness caused by Gu Zheng's appearance among the clan, and then took the initiative to come to Gu Zheng's side, waiting for the next order from the strange snake owner.

‘Follow me.’

'This kind of low-level territory is not suitable for you and me. Only with me can you become promoted to a higher bloodline.'

‘So, your decision?’

"Woof woof woof!!"

Without further ado, looking at the firmness in the eyes of the big dog, Gu Zheng understood the other party’s choice.

During the more than a month of guarding the law, the leader was actually ready to wander around the world with Gu Zheng.

Since it signed a master-servant contract with Gu Zheng, the big dog understood that its clan could not have a man-controlled monster as their leader.

Its last destination is probably to be placed on the magical black snake.

Therefore, the original leader was quite decisive at this time.

Even though Gu Zheng is so huge now, it still carried the other party on his body very loyally.

The evening in the Black Forest is very depressing for many monsters.

Today, for the overlord Black Demon Dog family in the Black Grassland, this kind of depression is particularly serious.

The whole clan has a total of twenty-nine black demon dogs, and today they sent away the strongest clan leader in the clan.

From now on, the most promising demon dog in the Black Demon Dog family will embark on a completely different evolutionary path from them.

A group of dogs with tears sent away their leaders.

Their inner entanglement and relief are so obvious.
