She held two daggers in her hands, and her eyes were filled with a sharp killing intent.

The dagger was aimed at the back of Lu Yuan’s neck, which was not covered by his armor.

As the dagger approached the back of his neck, the elven girl’s eyes flashed with a hint of surprise.

Success!

Her Tier 1 combat technique was at leader level, and its destructive power was extremely strong. The genetic warriors she had assassinated were simply unable to defend against it.

Along the way, she had relied on her invisibility and powerful attacks to kill many genetic warriors.

Ding!

At this moment, the dagger landed on the back of Lu Yuan’s neck, making a clear sound.

The feeling of being stabbed on an indestructible steel made the elven girl’s smile freeze, and her pupils shrank violently.

What kind of defense was this?

Her scalp went numb, and without thinking, her slender waist bent back exaggeratedly, and her body jumped back as if she didn’t need to stop.

However, she had only retreated less than a meter when a dark red sword light flashed past. The elven girl’s consciousness fell into darkness.

Lu Yuan, who was holding the dark red blade, had already turned around. He looked at the corpse on the ground with a hint of surprise in his eyes.

This elven girl was a little strong.

Lu Yuan’s current perception ability was actually not considered weak.

However, he still couldn’t find the invisible elven girl.

It was not until she revealed herself and began her assassination that Lu Yuan sensed the danger.

Moreover, the power of her combat skills was quite strong. He could feel pain when he was stabbed in the neck.

This elf girl probably had a leader-level gene engraved on her.

The elven girl’s body turned into a white light and disappeared, leaving a pile of spirit geno fluid on the ground.

Lu Yuan’s eyes lit up, revealing a hint of surprise.

He picked up the items. There were a total of 78 tubes.

In addition to the spirit Geno fluid, Lu Yuan also obtained another item.

It was a red hexagonal metal pillar.

The information appeared in Lu Yuan’s mind.

[ X211 fire grenade: explosive power equivalent to a Tier 2 low-level leader’s full-powered attack. ]

Lu Yuan’s pupils contracted slightly as he looked at the grenade.

It was actually equivalent to a blow from a Tier 2 low-level leader?

If he were to be hit by the explosion head-on, he would be injured even with his current defense.

This elven girl’s harvest was really good.

As expected, she was quite strong.

It was a pity that she was unlucky to have met Lu Yuan.

Lu Yuan smiled and collected all the dropped items. He continued to move toward the hundred-meter-tall building, absorbing all the spirit geno fluid on the way.

……

The hundred-meter tall building was surrounded by low steel buildings, and in front of it was a small square with a radius of more than two hundred meters.

There were teams of mechanical guards patrolling near the square, and there were as many as ten teams.

The weapons in each of the mechanical guards ‘hands seemed to be of a higher grade and more complicated than those of the mechanical guards patrolling the streets.

At the entrance of the building, there was a three-meter tall mechanical warrior carrying a giant steel axe.

Just by standing there, the iron warrior gave off a strong sense of oppression.

There was only one street outside the plaza, and on one side of the street, three guilds were vigilantly sizing each other up.

In the distance, there were corpses of various races.

It was impossible for these people to be the only ones who had discovered the 100-meter-tall building, but the others had already died in their hands.

The three groups consisted of six houndhead men, five Kamen, and seven green goblins with green skin and red eyes. They were about 1.5 meters tall, with two curved horns on their heads.

The dog-headed people, Kaman people, and green devil people stood in a triangle, and the atmosphere was heavy.

They looked at each other with vigilance and cold killing intent.

After a moment of silence, the leader of the group, a two-meter-tall giant dog-headed man with a black iron staff in his hand, revealed a sinister smile.

“Our strength is about the same, so a confrontation here won’t solve anything. It’s just a waste of time. Every minute and second in the remains is very precious. You don’t want to waste it here, do you?”

The leader of the Kamen was a warrior with a giant axe. He looked at the houndhead man coldly.

“What do you want to say?”

The dog-headed man laughed. “What I mean is that we should work together and kill all these mechanical guards. After we take down this building, we will use our own abilities to fight for the spoils of war. What do you think? ”

The leader of the green devil men held a dark green staff and was surrounded by green mist.

He looked at the Kobold, then at the Kaman, and said in a sharp voice,

“Who knows if you’ll secretly plot against us?”

The Kaman people looked at the kobolds and green devils with distrust.

After all, this was the Aier mechanical ruins, and there might be a lot of good things in the hundred-meter-tall building. They were all of different races and did not even know each other, so how could they easily believe the words of a stranger?

These three teams had all displayed great strength before, so they were all filled with fear of each other.

“I’m Yu Wu, the 3rd son of the chief of the Iron Teeth tribe. In the name of the Iron Teeth tribe, I promise that we won’t harm our allies before we conquer this tower.”

Yu Wu grinned and said,

“We don’t have much time. Don’t forget that we’re not the only ones in this area. No one can guarantee that there won’t be other experts coming. Every second we waste here, the bigger the change. At that time, the treasures inside might not be ours! Are you just going to wait here?”

Hearing Yu Wu’s words, the Kaman and green devil people’s eyes flickered.

This was also what they were worried about.

There were too many genetic Warriors that had come to the Aier mechanical ruins.

Although a large number of weak guys had been eliminated in the beginning, there were definitely many strong people who had remained.

In fact, there might even be existences that were more powerful than them.

If someone else had their eyes on this tall building, they would have to face even more opponents.

After a moment of silence, the leader of the Kamen spoke first,

“Then Let’s cooperate! I’m Bammou!”

The red eyes of the leader of the green devils flickered and he revealed a wretched smile.

“I’m Nina, happy working with you.”

Yu Wu heaved a sigh of relief, and a smile appeared on his face.

“Very good! “The Mech warrior guarding the gate looks very strong. However, with the strength of our three teams, it should not be too difficult to break through this tall building.”

“There’s no time to waste, then let’s do it!”

Bammou said somewhat anxiously.

Nina nodded. Just as he was about to speak, everyone’s expression changed slightly and they turned to look at the street behind them.

A human man in black armor jogged over from the far end of the street.

Upon seeing this human male, the members of the three teams were stunned.

Yu Wu grinned hideously and said,

“Human? He was actually still alone? You dare to come over here?”

Bammou held the battle axe in his hand.

“Kill him, then quickly take action before more people come.”

Nina smiled, and a green light appeared on the staff in his hand.

In the next moment, a green arrow was shot towards the humans in the distance.

……

Lu Yuan walked along the street towards the 100-meter-tall building. He realized that the closer he got to the building, the fewer streets there were.

It was as if all the side streets were converging towards the main street, and soon there was only one main street left.

Lu Yuan jogged along the main road and saw more than a dozen genetic warriors gathered at the end of the road.

These genetic warriors were divided into three groups and were looking at each other.

Lu Yuan raised his eyebrows. He did not stop and continued to approach them.

From what he could tell, these three teams didn’t seem to be much of a threat to him.

He planned to get rid of all three teams before going to the building.

Just as Lu Yuan ran a few steps, a green arrow was shot at him.

The one who launched the attack was the green devil.

Lu Yuan was stunned.

He hadn’t even launched an attack yet, and these people had already attacked him.

The corner of Lu Yuan’s mouth rose, revealing a smile.

It was pretty good.

He clenched the dark red blade tightly, and the power in his legs exploded.

Boom!

A spider web-like crack appeared on the ground. Lu Yuan’s speed increased sharply. His figure flickered and he dodged the green arrow, rushing towards the three teams.
