The world's largest wolf is 2 meters long and 1.1 meters tall at the shoulder, and the wolf that appeared in front of the Dongfeng ironclad car obviously exceeded this value. The head wolf has gray hair, a pale complexion, a slender nose, a pair of oblique triangular eyes glowing green, low canopy teeth, thick and vigorous limbs, a body length of nearly 3 meters, and a shoulder height of nearly 1.5 meters. Standing in front of the Dongfeng Iron Armor, the threat is full of momentum.

"It's a real wolf." Wang Jiaer almost stuck to the car window to look at it, looking a little strangely excited.

"Oops, it's actually a mutated wolf pack, and after the zombies of people and animals, the animals have also mutated. After the Dark Moon, the world is getting worse and worse, so how can humans survive?" Bai Zhen said worriedly.

"Grandma's, I only thought that there would be no zombies without people, but I didn't expect animals to mutate, this is the rhythm of using a whip to force me to improve. It's going to be harder to catch them in the future, my food! Wang Jiaer wailed.

The originally dignified atmosphere was interrupted by Wang Jiaer, and the painting style was suddenly crooked.

Su Ruolan smiled knowingly. Qin Zhihan picked up the walkie-talkie and said calmly: "The mountain road is steep, don't use bombs, let them feel the strength of our wolf company." ”

The head wolf felt neglected, and became angry, his ears were flat and outstretched, his eyes were wide open, and he raised his head and roared, and a wind blade quickly slashed towards the Dongfeng Iron Armor. Other mutant wolves also launched a collective attack, dividing up their work, some slamming into the car in an attempt to knock over the car, and some slashing through the roof door with their sharp claws, scratching people inside.

The front of the ironclad car was quickly covered in hard steel, and Shengsheng took the attack, leaving a deep mark on the car. Wang Jiaer forcibly suppressed the blood and qi in his heart, and said seriously, "It's actually the wind system, the second-level peak." ”

"It's left to me, and you go deal with the other wolves." Qin Zhihan was full of fighting spirit.

Since the end of the world, humans have struggled with the Chaos Zombies for two years, gradually awakening their abilities, slowly building bases, and adapting to survival and development. The first zombie cat appeared in the last three years of the apocalypse, and then animals began to be zombieized in various places, and at the same time, the zombies transformed by humans also appeared with special abilities, and the struggle between humans and zombies became more acute and intense. Some small bases were simply disbanded or wiped out. In the last four years, the dark moon is coming, not only the human world is full of mourning, but real events have been exposed, and many people can't stand the huge psychological pressure and choose to commit suicide with their families; Moreover, the zombie world has also been affected, and zombies and zombie animals have become sluggish, slow to react, and even hibernating, and humans and zombies have entered a period of relative peace.

But since the end of the world, in addition to encountering the unknown level of the sound zombie, the highest level zombie known in human society is the second-level high-level, and the mutant wolf in front of him has broken the historical record. According to the combat power of animals of the same level, which is half a level higher than that of humans, this wolf is already equivalent to a third-order human ability. And there is only one person with the strongest ability information that has been circulated by the human race, and the thunder system is a third-level high-level.

Su Ruolan had heard of the deeds of the strongest, but she had never been able to meet them. She didn't know if the thunder and lightning she saw slashing zombies the last time she was alive and dead was her hallucination, or if it was a real thing. But even if Qin Zhihan has a dual-line ability, he doesn't meet the characteristics of the strongest. This time the situation is critical.

Qin Zhihan held the platinum golden sand eagle and shot specifically at the eyes of the mutant-headed wolf, fast and accurate, several bullets in a row, getting out of the car while hitting and constantly approaching the head wolf.

Although he had never seen a bullet, he instinctively sensed the danger, and the head wolf ran from the side to get out of the way. One forward, the other sideways, staggered, Qin Zhihan and the head wolf switched positions. Behind the head wolf was Su Ruolan, who was poised to attack.

Qin Zhihan shook his head slightly, and said loudly: "Come here, let me see what you are capable of." Then he raised his gun and shot at the head wolf again, this time the bullet was castrated directly at the lower three-body, and he continued to run forward while firing.

The head wolf was suddenly angry, ignoring Su Ruolan and the other wolves behind him, and released a giant wind blade, chasing after Qin Zhihan.

Su Ruolan instantly understood Qin Zhihan's intentions, and followed not far behind.

Qin Zhihan ran forward desperately, taking advantage of the crooked mountain road, awkwardly avoiding the wind blade, the clothes on his body were constantly torn, and countless small wounds were oozing blood beads.

The head wolf chased after Qin Zhihan, and Su Ruolan put ice spikes behind her, like the thickness of an adult's forearm, and flew towards the wolf with a roar. The head wolf sensed the threat behind him, hurriedly avoided it, turned his head to glance at it, and continued to chase Qin Zhihan, who let this man make such a move, bite him to death first.

When Su Ruolan interfered, the head wolf's pursuit paused slightly, and Qin Zhihan gained a little respite. The two and a wolf chased each other like this. When Qin Zhihan was in crisis, Su Ruolan attacked behind the head wolf, and when the head wolf was angry and turned around to chase Su Ruolan, Qin Zhihan attacked in three ways behind the head wolf, and the head wolf was so angry that the head wolf lost his hair and chased and bit Qin Zhihan madly. Fortunately, Su Ruolan has just been upgraded to the second-level high-level, although her strength is not as good as that of the head wolf, but the head wolf can't help her if she runs away with all her might. Coming and going, it is dozens of kilometers away from the wolf pack. The head wolf also gradually understood the strategy of the two, slowed down, and stopped on the mountain road, and the two sides fell into a stalemate for a while.

In the early hours of the morning, although the sky gradually whitened, the moon still hung in the starry sky. The head wolf suddenly roared at the moon, his body swelled rapidly, and his belly was as big as a drum.

"Oh no, it's going to make a big move." Qin Zhihan and Su Ruolan were aware of the unusual flow of air at the same time.

With the head wolf as the center of the axis, the air rotated rapidly, and the air flow was sucked under the head wolf from all directions, and the head wolf's figure was gradually surrounded, and a tornado visible to the naked eye gradually appeared.

"You can't let it work at full strength." Qin Zhihan's luck condensed, and a huge hollow fireball gradually formed between his hands, and he vaguely saw a trace of thunder and lightning flickering on the edge of the fireball, and continued to compress and become smaller, smaller and smaller, from the basin to the size of a football, the fireball became more and more condensed.

Su Ruolan no longer retains her strength, and condenses the ice spikes with all her strength, from small to large, getting bigger and bigger, approaching 2 meters.

Now it's a matter of speed, to see which side can complete the attack faster.

The tornado finally roared, and although it was only seven or eight meters high, it destroyed everything in its path. The surface of the mountain road is broken, the cement layer rises from the ground, the boulders on the mountainside roll down, the trees break at the waist, and some fly in the air. All of this, with a ferocious killing intent, rushed towards Qin Zhihan and Su Ruolan.

At the last moment, the fireball in Qin Zhihan's hand and Su Ruolan condensed into an ice spike that had already taken shape and crashed towards the eye of the tornado. With a bang, the energy impact of the three was huge, directly collapsing the place where they were. The two of them fell off the cliff as a wolf. Qin Zhihan was very close to the head wolf, facing the enemy head-on, withstanding most of the attacks, being seriously injured, and a trace of blood overflowing from the corners of his mouth, and descending quickly. Su Ruolan landed above him, seeing this situation, she took out a nylon rope from the backpack that connected the space behind her, wrapped one end around her wrist, and quickly threw the other end towards Qin Zhihan, wrapped around his waist, and with a force in her hand, she swung Qin Zhihan towards the top crown of the forest next to him. With such a big move, the speed of decline became faster, but it surpassed Qin Zhihan.

Qin Zhihan had just landed on the top of the tree, and was about to pull Su Ruolan up, when suddenly a wind blade cut the nylon rope.

Although the strength of the head wolf alone is higher than that of Qin and Su, Su Ruolan has reached the second-level high level, and Qin Zhihan is the second-level peak, and he did not get a good deal under the siege of the two, but was injured in the end, and fell faster than the two. Seeing that Qin and Su were helping each other and were about to get out of trouble, they were even more unwilling, and condensed into a wind blade to cut off the connection between Qin and Su. If I can't kill you, I will take away your woman, so that you want to cut off my children and grandchildren, and you deserve it. The head wolf thought with hatred in his heart.

Su Ruolan was engulfed and fell by the last cyclone formed by the head wolf, and her eyes met Qin Zhihan's eyes, and the last picture that came into her eyes was his anxious and annoyed expression, and he stretched out his hand to her but didn't catch anything.

One drop of water on the face and two drops of water on the face. As soon as Su Ruolan was excited, she immediately sobered up, sat up immediately, looked vigilant, and prepared to meet the enemy.

"You're awake." A familiar mechanical voice remembers.

Su Ruolan raised her eyes and looked around, only to realize that the surroundings were very familiar, and this was not her own space. But there are nuances, which are twice as large as the original.

"When you were promoted to the second-level high level before, the space also had the conditions for upgrading, but the previous environment did not allow it, so I suppressed it. This time you were injured again and fell unconscious, so I had to absorb all the remaining crystal nuclei to heal you, and I couldn't suppress it anymore, so I had to risk upgrading. Fortunately, when upgrading, the energy is more riotous, otherwise it would not be able to suppress the little wolf. "Returning to zero explains Su Ruolan's situation after she fell into a coma.

"The wolf is also in space?" Su Ruolan asked in surprise.

"Yes, I don't want to say it, but that man is really good. Finally, a bolt of lightning struck the wolf. The wolf's heart and mouth blood are swallowed by you a little bit. When I summoned you in, it followed. However, the man's serious injuries should be well cared for, otherwise he will be left with the root of the disease. Zero said with regret.

Su Ruolan was shocked, she had known Qin Zhihan for a short time, but she had to be taken care of and rescued by him many times, this friendship was deep and could not be forgotten, and I still don't know how his injuries are and how to repay them in the future.

"You said the wolf came in, where is it now?" Su Ruolan asked.

"Confined in that corner, what are you going to do with it, contract? Although it hurts you, its strength is good, I haven't transformed yet, and it can protect you from the outside. Zero said as a corner of the space that had been murky became transparent. Inside was sealed a silver gray wolf lying on the ground with serious injuries, although he was mentally weak, his eyes were not less ferocious.

"Zero, how much can I contract?" Su Ruolan heard for the first time that she was able to contract animals, and she couldn't help but be very curious.

"At present, there are 2, including 1 soul contract and 1 master-slave contract. When you are strong and I continue to level up, the number of contracts will continue to grow. Zero said proudly.

"I'll definitely try my best." Su Ruolan was very happy to hear that she could transform into a shape when she returned to zero. After several life-and-death situations, Su Ruolan has full trust in Zero and hopes that he will get better and better. "Then how do you sign a master-slave contract?"

"It's very simple, as long as it presents you with a drop of essence blood and swears to be loyal to you for the rest of your life, you can establish a master-slave contract in Zhihai, and you can decide its life and death in one direction in the future. You give birth to it, you die and he dies, and his death does not affect your survival. The little wolf's heart blood contains some essence blood, and now as long as it completes its oath, it will be fine. Zero explained in detail.

Su Ruolan nodded and slowly walked to the corner of the confinement. He stood there silently, not saying a word.

The silver gray wolf looked at Su Ruolan with a fierce gaze, but he still couldn't hide a trace of panic about the unknown.

"You only have two paths now, surrender or die." Su Ruolan said coldly. "Surrender, I will make a pact with you, and from now on go side by side; Otherwise die. I'll give you half an hour to think about it. ”

"We wolves are a noble race, so we will not be slaves to humans." The silver gray wolf stared at Su Ruolan hatefully.

Su Ruolan found that there was an immature little boy's voice in her head, and she was almost startled, "Zero, what's the situation?" ”

"It's now halfway through the contract with you, and you can sense its thoughts in this space. Even if you want to set it free, it's impossible. No contract, I will kill it, our secret cannot be exposed. Zero said evilly.

Su Ruolan was embarrassed. Looking at this silver gray wolf, he said sincerely: "Surrender to me, I guarantee that you are not a slave, you are a partner, trustworthy, and the kind of relationship that can be entrusted to your back." ”

"How cunning humans are, I don't believe they are so kind." The silver gray wolf was skeptical.

"Now you can only trust me." Su Ruolan said.

"I don't surrender, I'd rather die." The silver gray wolf howled.

"Are you still young and have no unfulfilled wishes, and you are so willing to die? I promise you, as long as you don't betray me, I will break the contract after five years and give you back your freedom. Su Ruolan looked at the silver gray wolf and said sincerely.

As if remembering something, the silver gray wolf was silent for a while, and then said firmly: "There is no one who betrays his partner, I believe in you." I make a pact with you, and I hope you will keep your promise and set me free after five years. ”

Su Ruolan and the Silver Gray Wolf completed the oath-taking ceremony.

"Welcome, my partner, I'm Su Ruolan."
