Soon, the sky turned dark. Su Bai took the cub to find a spot suitable for a rattan hut.

After several hours of searching, he still did not find anything interesting. The so-called ruins could not be found at all, and he was also unable to figure out the rays of light's source.

Su Bai seriously suspected that this was a relatively special phenomenon that did not have a physical trace.

Rather than looking for some relics, it was better to find some spiritual plants in this Thorns Forest.

He was completely disappointed about this place. He decided to eat some dry food for dinner while the pets fed on medicinal cakes.

His original plan to make new potions for the fox after eating dinner today had been disturbed by Wei Ya's sudden arrival.

"Howl!" Ah Bai, what do you want to eat? I will go and catch it for you.

After finishing its potion, Purple Jade walked over and blinked at the sight of him eating dry food.

The dino, fox, and dragon also gathered and leaned on him. Even if Su Bai said he wanted to eat a phoenix, they would catch it for him.

"Thank you, guys, but no need; this is enough."

He smiled and caressed their heads.

After his meal, the Blood Dragon shrank and wrapped itself around his wrist again. Su Bai then kept the Mewling Fox and Little Tyrant into his contract book.

In the cold night breeze, he slowly fell asleep while holding the cub.

The next day, he no longer looked around blindly but pulled out the wood-poison attribute light balls from the spiritual grass nearby. He then infused these light balls into the cub's vines.

After a long time of not using his ability to pick up light balls, he found that this ability had greatly improved. Previously, he could only pick up a few attribute light balls at a time, but now he could pick up lots of them at one time.

For example, he could only pick up four or five attribute light balls for the vines at a time previously. Now, he could pick up all one-third of the light balls of a vine. This ability of his had not just improved by half.

The cub unleashed a vine with thick cyan thorns which was as big as Su Bai's arm after being infused with several attribute light balls.

Strengthen +1 +1…

After infusing the vines with a few more light balls, they became as thick as his thigh, and their color changed from light green to emerald green, then from dark green to deep green.

Once their color reached deep green, Su Bai infused them with more light balls, squeezing them full.

I feel like they're going to explode if you keep stuffing them. The cub blinked at him.

"It's alright; just control it a bit." He gently caressed his pet's head.

With the integration of more light balls, the vines finally changed again. In the end, they became thicker in size, reaching a terrifying degree of one-meter thickness. Their whole body was deep dark with bright metallic luster, and sharp purple barbs grew out from them as well.

Wow, they're so thick and big. Too big, in fact! I don't think I can control them anymore.

The cub looked at the terrifying and hideous giant vines in front of it. They were too big and thick, even more so than itself.

"It's okay. Just get used to this; you can always control them." Su Bai looked at the vines in satisfaction. Their strength was probably reaching a high-level monarch?

Su Bai dared to conclude that no ordinary monarch fire pet could destroy these vines.

Wow! You are awesome; I love you! The cub licked his face happily.

"Come here and release some vines before we continue," said Su Bai with a smile.

"Howl~" Okay!

The cub quickly released some more vines.

While searching for possible relics in this forest via anomalies, he incessantly strengthened the cub's vines.

Everyone else who was on a treasure hunt in this Thorns Forest felt like something was wrong with the boy.

At first, they could not understand what he was doing, and it was not until the entire Thorns Forest withered two days later that they had come to a realization. It turned out that the surrounding Thorns Forest had been withering day by day.

Three days later, he looked at the Thorns Forest, which had completely withered, and bowed deeply. Sorry, he felt guilty.

"Howl…" I'm sorry; I'm the one who is guilty. Ah Bai is not at fault. The cub also bowed and apologized silently.

All its vines in the Thorns Domain had been strengthened by Su Bai into huge vines with purple barbs and metallic luster.

Moreover, because the cub's Thorns Domain was currently only seventy meters in size, the thickening of the vines at that time actually caused some others to be unable to emerge.

At this moment, the ten feet light rays above the forest suddenly shrank and turned into a Rainbow Flower.

"F*ck! The Rainbow Flower is real. It has actually appeared. Oh, my God."

"What the f*ck! We actually had to make the entire forest wither before the Rainbow Flower appeared?"

The other people returned to their senses from the shock of seeing the nine-colored Rainbow Flower in the sky. It was actually real!

At that moment, countless people with flying pets began rushing toward the Rainbow Flower as they started melee fights.

Very soon, pets died, and humans bled. Finally, someone managed to get close to the Rainbow Flower, but he actually passed right through it?!

It was intangible?

He could only see the flower but could not touch it?

"F*ck! Stop fighting; we can't even touch this Rainbow Flower!" someone shouted.

Many people stopped fighting, while some really tried to touch the flower. Indeed, it was untouchable.

"The Rainbow Flower?"

Su Bai stared at the nine-colored Rainbow Flower in the sky. He had caused this to happen?

Upon taking a closer look, a line of small fireflies appeared before his eyes: [This is a projection of the nine-colored Rainbow Flower. The real Rainbow Flower is located in the depths of the rainbow ruins.

[It was condensed because of the lack of power to seal the rainbow ruins.]

Lack of power?

Su Bai looked at the profile in front of him. He had used the light balls to wither the Thorns Forest and made the Rainbow Flower emerge.

Thinking about it this way, he understood that he must quickly kill all the remaining light balls in the Thorns Forest.

Although the cub's Vine Whip had reached its limit and could no longer absorb the light balls, it did not matter as the light balls would automatically dissipate in less than a minute.

A few hours later, the entire Thorns Forest was withered completely, and the projection of the nine-colored Rainbow Flower in the sky suddenly fell into the Thorns Forest and turned into a door frame hundreds of meters tall.

The door frame was light blue and looked like an ice-carving, with dense and primitive patterns engraved on it. Inside the door frame was a nine-colored spatial vortex.

This was obviously a space door.

"What the f*ck! The gate of the ruins has really appeared."

"Rainbow ruins, here I come!"

The adventurers in the Thorns Forest were so excited that they jumped into the spatial gate one after another.

Seeing them jump inside one by one, Su Bai shouted in reminder, "Be careful of danger inside! If you go in, you will be killed."

However, as soon as his voice fell, someone sneered. "Coward! Since I dare to come into the wilderness, how could I be afraid of death? How can I climb to the pinnacle of a Pet Tamer without risking my life?"

After speaking, this person jumped into the spatial door. Everyone else also sneered and jumped in without hesitation.

Seeing this, Su Bai shook his head helplessly. Since they had chosen to go in, he just hoped that they would not regret their choice in the future.

He said this because he knew the meaning of the patterns on the door. It meant that the ruins would only remain open for thirty minutes, and only one person would come out alive after entering.

After almost everyone had entered, he followed.

In fact, he was not sure if anyone who went in had a monarch pet. After all, with the pet book, there was no way to estimate the opponent's strength before fighting.

After entering the Rainbow Gate, only one person could come out. If there was someone with a monarch pet, he would be in great danger.

However, he did not worry so much and directly went in. No matter what, he really wanted to obtain the Rainbow Flower in exchange for Chen Ruoxue.

After entering the spatial door, he thought that he would come into a space full of spiritual energy and treasures, but the real situation was not like this.

He found that he had come to a ruthless world made of light blue ice. In the center of this world was a large humanoid ice statue.

Information of the status soon popped up in front of his eyes. This was a candidate base for the successor of a card family which had already gone extinct. This candidate base belonged to the Ice Card family.

Just touching this statue would activate the so-called candidate system.

Su Bai walked over and touched the huge statue. He was then directly teleported to an arena.

Opposite him stood a strange burly middle-aged. Beside the man was a peak high-level wood monster, the Multi-colored Tree.

Not long after, nine other people appeared in the ring.

Once the ten people appeared on the ring, a strange voice sounded out of thin air. Although he could not understand it, he could understand the meaning: 'Once the battle begins, there can only be one living person to be promoted.'

"Multi-colored Tree, use Wood Poison!"

Without a word, the middle-aged man on the opposite side issued an order to attack Su Bai, who was closest to him.

Upon receiving the owner's order, the Multi-colored Tree rushed to him without a word and spat out a dark green acid.

At the same time, other people also launched fierce attacks.

"Howl! (▼ヘ▼#)" You are looking for death! how dare you try to hit my Ah Bai? Suffer under my lightning whip!

Letting out a furious howl, the cub unleashed a huge vine whip and swept over. The attack directed toward them exploded into thin air, while the vine whip swept across and directly sliced the Multi-colored Tree in half.

"F*ck! This is a vine whip?" The middle-aged man's eyes widened at the unprecedented sight of such a terrifying attack in his entire life.

"Hey, since only one person can walk out alive, then let them all disappear." Su Bai sighed. Since these people had chosen to come in, they had to bear the consequences of their choice.

"Howl!"

Nodding, terrifying spiritual power erupted from the cub's body, followed by its Thorns Domain. The thick horrible vines cleaned the place in just a few seconds.

The cub picked up ten backpacks with its spiritual power, cleaned the blood on them, and handed all to him.

Su Bai nodded and stuffed them into his space backpack.

He wanted to dissuade those people from coming in because they were too weak and were mostly at the warlord grade or had just reached the commander grade.

The Thorns Forest was an unpopular place, so the people who had come were naturally weaker.

He did not want them to enter because he did not want to bully the weak, but since those people refused to listen to his advice, he had no other choice.

In fact, as the person said, those who dared to come to the Scarlet Wilderness had already understood what they were facing.

Soon, he was taken away by the power of teleportation, and he appeared on a new ring.

Nine more people appeared one after another, and the game started with the same rule of only one person leaving alive.

"Brothers, this person appeared first, which means he finished the previous game the fastest. He is definitely the strongest here. Let's kill him first and then fight fairly among ourselves."

At the beginning of the battle, a coquettish woman in her twenties pointed to him as she spoke.

Hearing this, Su Bai looked up at her and the others and slowly smirked. "It's not that I look down on you, but nothing will change even if you attack me together. You are all trash."

"Brothers, did you hear that? Kill him!" shouted the coquettish woman.

"Flame Dog, kill him!"

"Pharmacy Rabbit, use Poisonous Kiss!"

...

A group of people commanded their pets to rush toward Su Bai.

"Howl! (▼ヘ▼#)" A bunch of garbage!

Purple Jade howled disdainfully and summoned its Thorns Domain from the ground. Countless terrifying vines entangled the area like giant pythons and strangled every pet alive.

From beginning to end, they were helpless, for they did not have any means of defense against these terrifying vines.

With a groan, the coquettish woman knelt and begged, "Big boss, don't kill me. I can do anything; I can do everything you ask me to do. As long as you don't kill me, you will be my master from now on…"

Terrified by this scene, she revealed not the slightest bit of viciousness in her attempt to survive.

"Jade, what are you doing? Su Bai frowned.

"Howl!" I just wanna see if she can continue being arrogant.

The cub ended her life with a vine whip and stuck out its tongue.

"The next time you do this, you can go to the contract book and reflect on yourself," he said angrily.

I was wrong; I won't do it next time. Purple Jade lowered its head and stuck out its tongue again.

Su Bai remained silent and collected the war gains by himself.

...

Time passed by, and in the blink of an eye, he had already gone through eight trials. It took effort and energy from the first spike to the last. At the eighth stage, he even needed to release the dino to defeat the stronger opponents.

In fact, Su Bai knew that he had picked up a bargain, and all he was facing was a bunch of crooked men.

If the people here were really of the same level as written on the door and were heirs of the card family, he would have fallen down a long time ago.

Fortunately, the card family had perished. Now, Su Bai was a little curious about what he would obtain after passing the test. Could it be a treasure of that card family?

Could it be a card or a pet egg?

With the power of teleportation coming again, he appeared on a new ring.

This circular ring was much larger than the previous ones, with a diameter of more than one kilometer. This time, it was not ten people but rather only five.

Each of them, however, was strong and had commander pets.
