Lu Tianyu stood at the exit of the passage and silently watched the battle between humans and the Taka people, it was the second time he heard about the Taka tribe, the first time was in the Blood Clan Castle, the old man named Prince Akhara gave himself a very dangerous feeling, and his strength should be very strong.

But it was the first time Lu Tianyu saw the complete form of the Taka people, which is a creature that looks like a reptile lizard on the earth, living thousands of meters underground all year round, adapting to the underground high temperature and high pressure environment, burly and stout, extremely explosive, fast and agile, flexible in action, rich combat experience, like close combat, Martian civilization calls them lizard people.

At the beginning, Lu Tianyu didn't want to get involved in this battle, of course, because he didn't want to expose himself.

But when Lu Tianyu saw that a soldier was ready to sacrifice himself and blow up the entrance of the passage to buy time for the other comrades to retreat, he couldn't think of it.

Maybe it was because they were both earthlings, or maybe it was because the sacrifice of this warrior infected him, Lu Tianyu was about to detonate the grenade, and his figure had already appeared next to the warrior, grabbed the warrior's neck and threw it into the passage, and kicked all the grenades towards the taka people with a flying kick.

With a "boom", the grenade exploded above the head of the Taka people, stopping the rhythm of the Taka attack.

The warrior was thrown into the passage by an inexplicable huge force, and looked around with a confused expression, when Wang Qiang, who was left at the end, rushed over, with a cloudy expression on his face, and he didn't understand what was going on.

Outside the passage, Lu Tianyu took out an electromagnetic pistol from the storage space, and began to shoot at the Taka people, a circle of visible ripples appeared in the air, a Taka man couldn't dodge, was hit by an electromagnetic bullet, the armor on his body had no defensive effect at all, and his body more than two meters tall was swept away by the impact and hit the wall behind him.

The other four taka people noticed that something was wrong, and looked around vigilantly for something, screaming "wow" from their mouths, while looking for objects to hide their figures.

At this time, whether it was the rescued search team or the Taka people with only four people left, they still didn't understand what was happening?

"Beware of ambushes!" A Taka man shouted to alert the surrounding Taka people.

"Bang bang bang!"

After a few more bullets, a Taka man hiding behind the pillar fell to the ground, and the Taka man hiding next to him saw ripples in the air, although there was still no trace of the sneak attack, but judging from the trajectory, the sneak attacker was next to the Taka man who had just fallen to the ground, and slashed at him with a strange scream.

The scimitar, more than a meter long, slashed at an extremely tricky angle, and the light of the knife cut through the air without the slightest hindrance or dullness, and the taka man immediately realized that it was not good, and just wanted to pull back, but then the dull sound of gunfire rang out again.

"It's an invisible man, be careful, get out of here!"

The remaining two taka people finally sensed that something was wrong, the other party had stealth equipment on them, which was not something they could fight against at all.

"Bang bang!"

Just as one of the taka people was about to turn and retreat, the gunfire rang out again, and even the most elite taka warriors could not dodge the ubiquitous sneak attack when they did not know the direction of the sneak attacker.

In fact, the perception ability of the Taka people is very strong, but they have never encountered such a situation today, but at the last moment of the death of the Taka people, they saw a shadow in the air, but they couldn't lock it at all, and it was impossible to retreat.

As the last gunshot rang out, there was a brief silence under the dome, Wang Qiang and the six soldiers watched the five taka people fall to the ground after being shot, and a monstrous wave was set off in their hearts, from the appearance of the sneak attacker to the total destruction of the five taka people, the whole process was less than thirty seconds, this kind of terrifying battle makes people's scalps tingle just thinking about it.

"Captain! All five Taka are dead! ”

"Isn't that nonsense?" A soldier peeked out from inside the passage, his eyes full of horror and disbelief, and wondered, "It can't be our reinforcements arriving!" ”

"We have reinforcements there! Let's go out and see first! Immediately report what happened here to the headquarters ....... ”

For Lu Tianyu, killing five Taka people was both a trivial matter and an accident, and he didn't take the feelings of the search team to heart at all, the only thing that made him feel a little unhappy was that he killed five Taka people and fired 9 shots, which was a bit low.

Lu Tianyu didn't have time to sigh, identified the direction, and continued to walk towards the center of the main city.

As you walk deeper into the main city, the surrounding buildings become more and more magnificent, and the decorations become more ornate, as if they are silently telling the glorious past.

The number of Taka people in the depths of the main city has increased significantly, and from time to time you can see a few Taka people hiding in the shadows, and even Lu Tianyu found hundreds of Taka people in a building, as if they were conducting unknown experiments.

In the face of so many Taka people, Lu Tianyu gave up the idea of cleaning them up, but the occasionally lonely Taka people were not so lucky, and before they could understand it, he sent them to hell.

After sneaking up on dozens of Takas, the Taka also seem to have sensed that someone had infiltrated the main city.

What Lu Tianyu didn't know was that the process of human exploration of the Ruins City was also a process of tug-of-war with the Taka people, so it had not been going smoothly, and so far the central area of the main city of the Ruins City was still controlled by the Taka people.

The human army often sends search teams such as Wang Qiang to approach the core area of the Ruins City, and the encounters between the two sides are carried out almost every day, but it is the first time that a Taka person has been killed by a human in the core area, and this time Lu Tianyu has stabbed a hornet's nest, and a large number of Taka people poured out of the nest and went in all directions.

Lu Tianyu avoided a patrol of Taka people, frowned, feeling that something was wrong, and he couldn't say anything wrong, and he didn't know that it was all because of himself.

When he was about to approach the central tower of the main city, Lu Tianyu found that the number of Taka people around the underground passage of the central tower had increased several times, and in the extremely wide passage, there were all kinds of strange-shaped equipment flashing with stars, which was the first time Lu Tianyu had seen the scientific instruments of the Taka people.

Lu Tianyu didn't feel strange when there was such a scene, the central tower of the main city was the core of the entire city of ruins, which was not only the center that controlled the entire city, but also the place where the central brain and force field device were placed, from the perspective of scientific research value alone, it was impossible for the Taka people to give up here easily, and it was not uncommon for a large number of Taka people to appear here.

However, so many Taka people are here, which has caused great difficulties for Lu Tianyu to sneak into the central tower, Lu Tianyu wandered around the periphery of the central tower for a long time, and found that there were a large number of Taka people in the eight passages leading to the inside of the central tower.

"I had to force my way in!"

Lu Tianyu assessed the strength of both sides, it was not difficult for his existing strength to enter the central tower, but it was a little difficult for the taka people to react and retreat safely.

What worries Lu Tianyu is also the reaction of the human race, once the battle starts, it will inevitably alarm the human army, and at that time, he will be exposed again, and it may not be easy to hide his whereabouts.

Lu Tianyu can't care about these now, there may be a gene therapy warehouse in the center tower that he needs, this is the only way to treat his sister at the moment, and he has to enter the center tower no matter what.

Lu Tianyu took out sixteen plasma grenades from the storage space, set the detonation time of the plasma grenades to half an hour later, and quietly placed two plasma grenades in each passage into the central tower, and then concealed them, and waited until they were detonated, taking advantage of the chaos to enter the inside of the central tower.

In a large conference room in the central tower, several Taka people in golden robes sat there, led by a Taka man who opened his long mouth full of sharp teeth, and let out a sharp roar from his mouth: "Tell me, why did a human stalker enter the central area, is it that the heroic Taka warriors are starting to coward, or is it that the humans have sent the ...... of the Awakened." ”

"Elder! We've sent all the warriors, and we believe it won't be long before we can kill this human! ”

The Taka people mistook Lu Tianyu for the awakened person in the human army, or the invisible person of the dark system, otherwise it would be impossible to inflict such a big loss on the Taka people.

"Elder, it's better for us to apply for sending our own Awakened One, only the Awakened can kill the Awakened, otherwise the price for our side will be too great."

"Then apply!"

The Taka Elder flicked his thick tail behind him and roared to the sky, "We must not abandon the central area of the Ruins City, where those despicable humans, hateful cockroaches, and insatiable parasites have snatched countless riches from the great Taka people, and it is time to teach them a lesson." ”

"Boom! Rumble! Rumble! ”

At this moment, there was a rumbling explosion under the entire central tower, followed by the ground began to shake, and the yellow sand fell from the sky overhead, and the whole building seemed to collapse at any time.

"What's going on?"

"Elder, it's a big deal, we've been attacked by a human army!"

The sudden news stunned the Taka people in the room, the reason why the Taka people can still occupy the central area of the ruins city is not because of how strong the technology of the Taka people is, but because the environment here is really not suitable for large-scale use of troops, plus the human beings do not want to be destroyed together with the city of ruins, the attack will inevitably be restrained, and they will not be able to carry out a large-scale attack on the Taka people, which the Taka people know very well in their hearts, but they don't want to admit it.

"Destroy all the passages connected to humans, there is no passage, see how humans attack!"

"But...... Elder! ”

The Taka people next to him were a little unwilling, when did the Taka warriors ever cowardly, and the humiliating retreat would make the Taka warriors lose the courage to fight, which was an unforgivable sin.

"It is my mission to keep our soldiers alive, I will not send our soldiers to the meaningless battlefield in vain, carry out the order!"

After a while, there was another "rumbling" vibration from the ground, and this time the vibration really attracted the attention of the human army, and soon the human army sent its own soldiers to the explosion point.

When the human soldiers saw the blown up passage, they had no idea what was happening, and it was the first time that the Taka people took the initiative to retreat, this is not the style of the Taka fighting at all, is there something big about to happen?

In the central tower, Lu Tianyu climbed rapidly in the ventilation pipe, ...... tenth, twentieth, and thirtieth floors.

According to the data, the central tower is more than 600 meters high and is divided into three areas, upper, middle and lower, with a total of 88 floors. The lower area, which runs from the first floor to the forty-ninth floor, is the core residential area and where the elite of the City of Relics live. The middle floor, from the 50th floor to the 79th floor, is the core office area, which is responsible for controlling the operation and supervision of the entire ruins city.

The most important core area is located on the eighty floors of the upper area, where the central brain of the entire ruins city is stored, and the next layer is the force field device generation area, which is responsible for providing a force field protection cover for the entire ruins city, which is also a sign of the fourth-level scientific and technological civilization.

When Lu Tianyu entered the office area and was about to look for another ventilation duct, a team of Taka patrol soldiers found the open ventilation duct cover, Lu Tianyu triggered the detection device arranged by the Taka people in the central tower in order to avoid the Taka warriors, and for a time the harsh alarm in the central tower suddenly sounded.

"Alert, alert! An unidentified object was found to have entered, and the target location was ...... on the 50th floor of the office area. ”

Groups of Taka people poured in from different places, hundreds of Taka people appeared in the office area of thousands of square meters, and a steady stream of Taka people were rushing from the lower to the middle level.

Lu Tianyu gave up the plan to continue stealth, the longer the time dragged on, it was only a matter of time before he was exposed, once the Taka people knew their destination, they would inevitably block the upper area of the central tower, at that time, not only would they not be able to reach the upper area, but even the chance of escape was slim.

"In that case, let's go on a killing spree!"

Lu Tianyu took off his invisibility cloak and put on the flying wings, which wrapped Lu Tianyu's whole body up and down, opened the electromagnetic protective cover, rushed towards the elevator area of the office area, and after dropping a few plasma grenades in the elevator, he went up the fifty-first floor along the stairs.

At this time, a large number of Taka people arrived, and saw that Lu Tianyu destroyed the elevator in the middle area, and could only chase Lu Tianyu along the stairs, but as soon as he stepped on the first staircase, a shiny ball rolled down above, and ordinary Taka people didn't know the plasma grenade at all, and they were curious to pick it up and take a look, the rough big hand of the Taka people had not yet touched the ball, and the ball suddenly opened on its own, splitting into upper and lower halves, and the upper and lower halves flashed with a trace of current, and the current in the ball filled the entire stairwell in an instant like a flood that opened the gate, The surrounding takas didn't even have time to scream before they turned into charred corpses.

"Plasma grenade! It's the mysterious man, grab him, catch him at all costs! ”

The Taka elders saw the silver snake filling the screen through the surveillance screen, and the first reaction was to become extremely excited, as if he had seen a peerless beauty.
