There are not many energy arrows, and Hong Yi needs to save some points, so now he basically relies on close combat. He has mastered various close combat tactics learned from the Evolution Branch. Even if he fights with students who are good at melee in the Evolution Branch, Hong Yi is confident of winning.

Through the two gates, Hong Yi finally arrived at the seventh floor underground.

The air here is colder, and even a thick layer of frost has emerged on the walls and floors.

However, when he arrived at the seventh floor of the underground, Hong Yi unexpectedly did not see any Wendigo. However, he still found blood stains in many places, which had turned into blood-red ice crystals, but it seemed that they had not appeared for a long time, and in addition to the cold, there was also a smell of blood in the air.

Hong Yi is now a mercenary, and the mercenaries have good noses and can tell the freshness of the bloody smell in the air.

Obviously, there was a massacre here not long ago.

But the weird thing is that there are no corpses here.

Hong Yi immediately became wary of the smoke and farts were next to him, and the little snake had already started to wander around to investigate the situation.

Most of the seven underground floors are various laboratories. Because the time is too long, many experimental equipment, including various utensils, have been scrapped and damaged. There are scattered paper scraps and balls of dark stains everywhere on the tables and the ground.

At this moment, a loud noise suddenly came not far away, and then two black shadows flashed, smashing the glass of a laboratory directly, and the things inside were flying everywhere.

"Smoke, go!"

Hong Yi had just seen it clearly that one of the two black shadows was a little snake. The other one didn't see it clearly, but it was definitely an enemy.

Yanba got the order. He immediately roared and pounced on it, and Hong Yi followed closely behind.

The little snake and the black shadow fought fiercely for a moment. The surroundings were in a mess. The power of the third-level mutant of ordinary people had exceeded that of ordinary people, or even more than ten times. Naturally, their attack power was extremely strong. Even some metal walls were still sank in the fierce battle.

At this time, the little snake was hit by the black shadow and was suddenly dispersed, and it was difficult to regain its shape for a while. Fortunately, the smoke fart was pushed up in time at this time.

Hong Yi could see clearly at this time. The black shadow turned out to be a very strange human figure.

He has a human body, but he has a long face that looks like an elk, his eyes are separated, his ferocious red, and his head is even more bizarre horns. His skin is tightly attached to the bone, like a skeleton, his arms are thick, and his teeth in his mouth are extremely sharp.

When Hong Yi saw this monster, his heart was thrilled. There was no doubt that this was no longer a third-level mutant of the White Star, but an existence that reached the fourth-level meter of the White Star.

In addition, Hong Yi felt a breath from the other party that was different from other mutants.

A little familiar, just like I've seen it somewhere before.

Hong Yi has no time to recall. Because Yanba is already fighting fiercely with the other party, the Yanba is at a disadvantage. Every claw of the mutant can tear off the flesh of Yanba. Fortunately, Yanba has the ability to speed and regenerate, otherwise he will have lost.

In this case, Hong Yi had to fight first.

Fire surged from the Night Blade, and Hong Yi jumped up and rushed forward. The mutant seemed to feel Hong Yi's threat, turned his head to look at Hong Yi, raised his claws and smashed it towards Hong Yi.

The next moment, the Night Blade collided with the claws of the mutant, and a spark immediately splashed out. Hong Yi immediately felt as if he was hitting a piece of diamond iron stone. A huge recoil force hit, and the Night Blade almost lost his hand.

Hong Yi immediately knew that this mutant was not simple, and his body was so hard that it was terrible. No wonder he was even defeated by smoke.

Seeing that the mutant was about to pounce on him, Hong Yi immediately condensed a ball of fire with his ring and threw it out.

No matter how you look at this variant, it should be a "Windigo". Bai Min said that from ancient legends, as long as it is Wendigo, you will definitely be afraid of flames.

The fireball exploded, forming a fire screen. The mutant was covered by flames and screamed and hurriedly retreated.

Hong Yi also retreated more than ten meters, and Yanba was covered with wounds. The largest wound was torn apart by half a meter long hole, and the flesh and blood were turned outwards. However, his powerful regeneration ability was soon repairing the wound. It would not take long for Yanba to recover as before.

Compared with the wounds all over the body of Yanba, the mutant on the opposite side was completely unscathed. Hong Yi clearly saw that it was hit by Yanba several times just now. How could this happen?

But soon Hong Yi felt relieved.

Simply put, the opponent's defense is too strong. Even the combat robot that is extremely expensive in the gathering place No. 7 and is equipped with fully protective alloy armor may not have this defense.

This can be seen from the moment when the Night Blade collided with the opponent just now. The sharp Night Blade, with the scorching heat of flames, only left a shallow mark on the opponent's palm.

Ordinary White Star Level 4, or even White Star Level 5 mutations have absolutely no such ability. Obviously, this mutation is extremely special. At this time, Hong Yi suddenly thought of where he felt that this mutation was familiar.

It is its breath, its breath is exactly the same as Lin Yun's breath.

Hong Yi himself analyzed the things that occupy Lin Yun's body. According to the pig demon's statement at that time, the other party was an existence that was a demon-level mutant from birth. Unlike other mutants that improved their strength bit by bit, they were mutants born with a "calling golden spoon".

Obviously, the same is true for this in front of you.

Moreover, the opponent's strength is real Baixing's level 5, which is extremely difficult to deal with. It can even be said that even with Hong Yi's current methods, plus Yanba and Xiaoshou, they may not be the opponent's opponent.

The flame of the fireball was extinguished at this time, and the "demon-level original body" screamed and rushed over again. Its speed was so fast that it only left a afterimage in the air.

"Smoke, block it!" Hong Yi immediately felt frightened. The strength of his body was much worse than that of Smoke. This monster's attack would even Smoke suffer severe damage. You can imagine what the consequences would be if it fell on him. I am afraid that the armor on his body would become something as fragile as paper. You must know that he does not have the ability to speed regeneration like Smoke. Once seriously injured, he will basically have a dead end.

Bang!

The smoke fart was like a flesh shield, blocking the opponent's heavy blow for Hong Yi. The bone fragments and skin on his body were removed, and blood and flesh flew everywhere. Hong Yi immediately retreated quickly and he took away the Night Blade. In this case, fighting with a monster with infinite strength and steel body was a problem with his brain.

Taking out the battle bow, Hong Yi activated the state vision, shot the weak point, and directly attacked with the flame arrow. This is the only way Hong Yi could think of to restrain the opponent.

Rockets passed by like lightning and shot towards the mutant, but only a few hits, and the others were avoided by the opponent. Fortunately, Hong Yi's attack also had a certain effect. Because the opponent was also afraid of the attack of the flame arrow, he was temporarily suppressed by Hong Yi, but it was easy to injure it, but it was even more difficult to kill it.

The little snake condensed its body again at this time, but because there was too little blood and flesh on the ground, its size became much smaller, but no matter what, it could come in handy at this time.

"Nuwa, think of a solution!" Hong Yi could only use the flame arrow to suppress the other party. Once the biological energy was exhausted, he would be in trouble. The smoke fart could only block it for a while, but he was no match for the monster at all.

"Later, I'm repairing the fire protection system, and the pipes can still be used!" After Nuwa said something stupid, Hong Yi immediately heard a series of strange noises, as if water was surging in the pipes.

The next moment, the fire sprinkler above the head suddenly exploded, and a stream of water fell from the ceiling like rain, instantly pouring everyone into a drool.

"Damn, this is what you think of?" Hong Yi cursed and thought that Nuwa was too unreliable. She asked her to think of a solution, but it caused trouble.

However, Hong Yi soon knew Nuwa's intention. After a large amount of water fell, the little snake quickly became like a fish in water, and immediately condensed into a huge body, reaching fifteen meters in length, as thick as a bucket of water. After condensed, it immediately rushed towards the mutant.

The water was cold and terrible, but Hong Yi was very excited because the little snake had the help of water at this moment, and its combat power increased greatly and continued to attack the opponent. Even if it was smashed by the opponent, because it was full of water around it, it would immediately regain its shape and enter the battle.

This also reduced Hong Yi's pressure and gave him time to take a breath.

With just a moment of effort, the biological energy in his body had been consumed by 80%. Without this water, he would really not be able to hold on.

"That's all I can help you. The weapons defense systems here are all external and cannot attack internally!" Nuwa said at this time.

"You have helped a lot!" Hong Yi breathed a sigh of relief. As long as there is water, the little snake is temporarily invincible. Its body is completely condensed with water and can be recovered immediately if it is broken. On the contrary, the little snake's attack made the mutant overwhelmed. Because of the closure, the water under its feet is already as deep as the knee, which is equivalent to creating a main battlefield for the little snake to benefit it. Although it may not necessarily defeat the opponent, it can at least compete.

Hong Yi knew that this was not a solution, but after thinking about it, he came up with a solution.

He also has a big killer weapon.

Sword of Stone-Suppressing.

As long as you use the sword skill "domain" carried by the Stone-Suppressing Sword itself, you may be able to kill this mutant.

Thinking of this, Hong Yi immediately took out the Stone Sword and began to activate it, allowing the Stone Sword to suck his own blood, because in order to fight the sword skills, there must be enough blood to support it.
