Ma Jiang and Qi Yun walked into the first floor of the building, only to find that the hall on the first floor was full of monster corpses burning with transparent flames.

"These are the genetic warriors of Aegis Corporation?" Qi Yun had a surprised expression on his face.

The strength of the genetic warriors has been passed down among the survivors, but no one has ever seen it, after all, it was decades ago.

Even if there are still genetic warriors, they are not accessible to mercenaries living in the lower echelons.

"Why are they all dead, they look like they just got killed, could it be that someone entered this building before we did?" Qi Yun glanced up at Ma Jiang and couldn't help but say.

"Be careful, that man must not have left yet, don't attract his attention!" Ma Jiang said in a low voice.

"Captain, do you think this person will be Song Jian?" Qi Yun stared at the corpses of these genetic warriors and couldn't help but speak, he felt that the wounds on the corpses of these genetic warriors had some familiar feelings.

"He? How is it possible, this is a level 20 monster area, these genetic warriors have superhuman physical fitness, and their strength is strong, and it is not at all something that he can kill as a god of more than ten levels. Ma Jiang shook his head and sneered.

In Ma Jiang's impression, Song Jian's strength is indeed strong, but to say that he can kill so many genetic warriors, Ma Jiang still doesn't believe it.

What he didn't know was that although these genetic warriors were powerful, they also had obvious weaknesses, and Song Jian happened to have mastered a sword technique that could target their weaknesses, making it much easier to kill these level 20 monsters than even level 15 monsters. Even the "One-Yuan Chaos Immortal Sword Body" was not opened, and the entire first floor was directly cleared.

"The one who killed these monsters must be a very strong adventurer, we are not his opponent, and the other party's target is not necessarily that perfect quality genetic modification potion......" Ma Jiang said secretly in his heart.

"Keep up, be careful, don't let him find us." Ma Jiang said in a low voice.

"Captain, what is there here, it's worth such a big risk...... Qi Yun hesitated, you know, it must be very easy to kill so many people who are level 20 genetic zombies, killing the two of them.

If it were usual, when they encountered such a strong man, their choice would be to leave quietly and not alarm each other, but for some reason, the captain Ma Jiang actually chose to follow behind this strong man......

"What is there that the captain is willing to risk his life to obtain?" Qi Yun secretly guessed in his heart: "Ordinary genetic modification liquid, it won't make him even want his life, there must be some special treasure here!" ”

Thinking of this, Qi Yun also showed an expectant look in his eyes.

"Looks like you guessed it!" Ma Jiang glanced at Qi Yun and said, "Yes, this company also stores a large amount of genetic modification liquid, as long as we obtain it, we can have great power and huge wealth, which is enough for us to choose a city and become permanent citizens." But, more importantly, there is a perfect genetic modification liquid based on the genes of ancient giant beasts hundreds of millions of years ago, and with it, we can become the top existence in this world! ”

"Think about it, once we get that kind of earth-shaking power, it will be easy to kill Song Jian, and when the time comes, you can also ask for slave status, and I promise you that it will definitely come true." Ma Jiang patted Qi Yun's shoulder, looking full of confidence.

"Captain, I listen to you, I will do what you say!" Qi Yun suddenly became excited.

Isn't great strength and abundant wealth the greatest pursuit of people after the apocalypse, and if it can really be achieved here, it is worth taking even a little risk.

"We should be glad we don't have to face these monsters directly!" Ma Jiang glanced at the burning corpse on the ground, shook his head and said.

In the information he obtained at the beginning, it was not said that this building had become a gathering place for monsters, with the strength of him and Qi Yun, I am afraid that even these genetic zombies on the first floor would not be able to defeat them.

……

Song Jian came to the second floor, pushed open the side door of the stairwell, and a gene zombie covered with spikes turned his head violently, the two looked at each other, the gene zombie showed its sharp fangs, and made a threatening move towards Song Jian, and the spikes on the surface of his body also bounced out in an instant, flying towards Song Jian like a bullet.

Bo Bo Bo ~ Seven or eight long thorns more than a foot long pierced the side door behind Song Jian, Song Jian reacted extremely quickly, dodged the attack of the genetic zombie with a roll, and slashed towards it with a sword.

Da Da Da ~ The genetic zombie held the micro rush in his hand and shot towards Song Jian, immediately leaving several blood holes on the surface of Song Jian's body, and a series of damage numbers emerged from the top of Song Jian's head.

Boom!

The Red Fire Heart Ape Sword slashed at the opponent's arm, swept the momentum, and swept the micro rush in the hands of the genetic zombie monster to the ground.

Soul Control Swordsmanship!

A transparent long sword condensed above Song Jian's head and slashed towards the top of the opponent's head;

Oh~

A terrible scream sounded, and the genetic zombie held its head, with a hideous expression of pain on its face, and kept rolling on the ground.

Song Jian quickly killed the defenseless genetic zombie, harvested a genetic modification potion, and two long thorns on its body.

These two long thorns are also a forging material, and after Song Jian glanced at them, he put them in the package bar.

The second floor is a room, and it seems that it is also a piece of laboratory, Song Jian was about to enter the second floor, but after thinking about it, he retreated.

He took out a piece of steel bar from the parcel bar, inserted it into the side door handle of the stairwell, twisted it into a twisted shape, and completely blocked the side door, and Song Jian continued to climb up.

His purpose was the "polymer analyzer" on the thirteenth floor, not to kill all the monsters in this building.

However, after getting the task items, it does not prevent Song Jian from leveling up here, as long as he does not encounter particularly strong boss monsters, leveling up here is even easier than in the fifteenth-level monster area.

In this way, every time Song Jian went up to the floor, he would use some materials in the package bar to block the side door of the staircase, and after he went up to the seventh floor and blocked the side door of the staircase, he heard heavy footsteps from the seventh floor.

"This is the BOSS who looked at me before......" Song Jian's heart sank, he didn't dare to make a sound, and waited until the boss walked away, and then cautiously continued to walk towards the upper floor.
