It is a lightning spire, which can attract lightning from heaven and earth to gather in the tower, and release it when needed, which is earth-shattering.

This is a unique structure in this world, extremely difficult to build, only some large settlements have enough resources and technology to build, and only a dozen of them will be built in fortress-like giant settlements like the City of Flames to withstand monsters from the depths of the wasteland, as well as outer gods and nightmares.

Lin Chen followed Lero and the others to the huge canyon, and could see an iron chain bridge made of several thick iron cables connecting this side to the other side of the hundred-meter canyon, a few hundred meters away from the wall of the Flame Fortress.

The cables were dark and dull, each one thick, and the cables were linked together to form the shape of a bridge, covered with thick planks large enough to accommodate two armored vehicles walking side by side.

This is the only way to enter the City of Fire, and other than that, either fly over it or bypass it from the far other side.

There is a small outpost checkpoint at the head of the bridge, Lero took them here, and stepped forward to negotiate with the defenders of the outpost, Lin Chen saw that they looked at him, one of the one-eyed officers nodded to him, and he also responded kindly, after a while Lero and the officer came over, Lero said:

"I'm sorry, Your Excellency, but according to the rules, everyone needs to check before entering the Flame Keep, including us."

Lin Chen raised his eyebrows and said:

"What to check"

The one-eyed officer said:

"Please rest assured, just check the contamination value and whether there are any infected people lurking, as long as it does not exceed a certain value, it will be fine."

"Come on!"

This Lin Chen is relieved, he has just come to this world, and he has not seen the so-called infected person, so he will definitely not have any pollution value, let alone be an infected person.

The detection is very simple, with a device swept back and forth on his body, the so-called contamination can be detected.

Watching them simply sweep back and forth, the green light on the instrument kept displaying, and Lero and the one-eyed officer knew that they had passed the test with a look of surprise on their faces when they saw the result, but they were not alert.

Just as the one-eyed officer took out a sign indicating approval and was about to give it to him, suddenly there was a scream from among the civilians behind him, and then everyone retreated like a tide, revealing a civilian lying on the ground with a severed head.

"Kill it!"

The one-eyed officer reacted immediately, pulled out his command knife with a 'choked' sound, pointed at the center of the crowd and shouted:

"Civilians gather on one side, and they must not run around, otherwise they will be killed on the spot!"

At this time, the body of the civilian lying on the ground had rapidly expanded to about three meters, looking like a little giant, and the outer layer of robe was torn open, revealing sharp bone spurs and a black shell.

"This is the Infected!"

Lin Chen asked in surprise, Lero was not surprised that he didn't know this, Lin Chen's identity was a traveler who had just entered this world, and it was normal not to know, and explained next to him:

"Your Excellency, this is a kind of infected person, the real name is Deep Diver, and it can be hidden in the human body at a deep level, and ordinary small settlements may not be able to find out if you are not careful."

Lin Chen nodded clearly, his eyes looked at the many civilians dressed in sackcloth who were driven aside, just now, he felt a strange fluctuation flash away, and asked:

"So what is the source of infection?"

"The source of the infected, the energy source continues to release the power of pollution, pollute and corrupt some weak and undetermined ordinary people, transform them into deformed infected, and drive them to destroy human civilization, many settlements are accidentally infiltrated by the source of infection, so that the entire settlement is destroyed."

Lin Chen: .....

He found the world to be a bit chaotic, steam, orcs, gods, gods, gods, nightmares, mutations, pollution, and other things he hadn't seen before, tsk, it was a hodgepodge, so messy that he didn't even know what to say.

However, the civilization of this world is really tenacious, and this situation can still be held, and it has not been destroyed, which is also admirable to him.

Lin Chen didn't know what the strange fluctuation he sensed just now, but it didn't prevent him from reminding them, he tapped his fingers on Lero's metal shoulder helmet and said in a low voice:

"I just sensed a strange fluctuation of power in that group of civilians, but I don't know what."

Lero's face immediately changed, he looked back at Lin Chen and nodded again, he immediately became serious, strode towards the one-eyed officer with a confession and whispered, and the one-eyed officer immediately shouted:

"Everyone, retreat to the outpost and send a warning fire to the fortress!"

With an order, the soldiers at the outpost immediately retreated, not even caring about the infected person who was deformed, and Lero also said to Lin Chen:

"Your Excellency, please come with me."

Seeing the soldiers quickly retreat to the high wall of the outpost, and the rows of weapons moved to the outside, the civilians who were being examined seemed to realize something, and shouted in horror, and many of them separated from the people around them, and shouted with their heads pulled down to reveal their own appearance:

"I'm not infected, and I'm not mutated."

Many people did the same to pull down the sackcloth to prove their innocence, but there were also many who did not pull down the sackcloth and stood silently in place without moving.

The one-eyed officer slammed his sword against a gong hanging from the wall, making a loud noise, and shouted:

"Don't climb the wall, step aside, or kill on the spot!"

But at this time, those civilians who stood in place without making a sound or moving had begun to show signs of distortion, trembling all over, and their bodies under the linen cloth began to twist and swell and deform, which made these civilians who were not infected with mutations frightened.

The one-eyed officer didn't ignore this, and sent a small number of sergeants over to watch, lest there be infected people who pretended to be civilians and fled to the back before sneaking up.

This kind of thing is not impossible, although the infected are like beasts without a little intelligence, but the source of the infection that directs them is wise, otherwise they would not mix in the fleeing crowd and want to steal into the Flame City, many of the poorly equipped settlements are destroyed by internal attacks in this way.

The infected are much stronger than the mutant monsters they encountered before, and their size alone is several times larger, and their combat power has increased by a large margin, looking at the number of infected people who are mutating, this outpost is estimated to be difficult to stop.

The one-eyed officer also seemed to notice this, and bowed his hand to Lin Chen:

"Please also ask your Excellency to help fend off these infected."

"I'll help you stop the source of infection."

Lin Chen didn't want this Flame City to be destroyed, he still had to survive for three months, staying in the city was definitely much better than staying in the wild.

With his assurance, the one-eyed officer was much more relieved, and it just so happened that the infected had already completed the distortion, turning into a three-meter-tall monster with twisted upper body muscles like a ball of flesh, and a large mouth full of sharp teeth flowing a cloudy liquid towards the city wall.

"Shooter ready!"

The one-eyed officer commanded the knife to be raised, and a large number of soldiers with steam guns on the watchtower opened a certain mechanism, and white steam began to emit from the steam canister behind it.

"Put!"

"Bang bang bang..."

With a series of loud sounds, metal bullets erupted from the muzzle of the gun, hitting the infected with precision, directly into the twisted muscles, large swaths of flesh exploding and pus spurting all over the ground.

On the sentry wall, a row of white steam rushed up to the old high, and a series of air pressure sounds sounded neatly.

This steam gun is really powerful, stronger than the power of ordinary modern rifles, only inferior to sniper rifles, that is, the rate of fire is a little slower, it takes about fifteen seconds to shoot a shot, after a wave of shots, immediately retreat and wait for the next wave of steam pressure to rise, another row of shooters immediately stepped forward to aim, and another row of bullets was shot.

It's just that this shot is very powerful, but the infected person's vitality is too strong, one shot knocked out a large piece of flesh and blood, and replaced it with an ordinary person to kill it directly, but for them, it was just a light shot, and as the flesh and blood squirmed quickly regrown, quickly approaching the sentry wall.

At this time, the other defensive weapons on the sentry wall came into play, there was a tall sentry tower behind the sentry wall, on which were placed two bronze steam crossbows, with a column of white steam rushing up, with a muffled sound, a giant crossbow the thickness of a baby's arm shot out, directly piercing an infected person and nailing it to the ground, the terrifying kinetic energy directly tore it apart, and the remnants of flesh and blood did not need to be wriggled to heal, but this damage was too great, exceeding its life limit.

The power of this bronze steam crossbow is very great, and Lin Chen's visual analysis of ordinary second-order powerhouses may be difficult to block, but the firing frequency is too low, and it takes more than half a minute to shoot a shot, which is quite easy to use against the leader, and it is a waste to deal with miscellaneous soldiers.

A large group of infected people rushed to the side of the outpost wall that was only five meters long, and began to frantically slap the sentry wall with their big claws, at first Lin Chen was puzzled that they were relying on this method to attack the city, and the next second he felt a wave sweeping, these infected people immediately rushed to the gate of the outpost, and slapped the gate one after another, and some jumped up along the city wall, and were quickly knocked down by the soldiers guarding it.

Lin Chen didn't even look in front of the gate, his eyes were fixed on one of the civilians who seemed to be scared on the ground, the corners of his mouth curled, a delicate longbow appeared in his hand, and a black iron armor-piercing arrow appeared in his right hand, put it on the bow, and slowly pulled it away.

This longbow is one of the collections of the previous world, given by the Son of Heaven of the human dynasty at that time, and is said to be one of the three famous bows that have been handed down since ancient times in the last world, called chasing the moon.

Lin Chen had tried it before, it was indeed a good bow, it was estimated that it was a war bow when the human world was not downgraded in ancient times, the material was very high-end, and with his strength, he felt that the bowstring was elastic enough.

Drawing the bow into a full moon, he loosened his fingers at the target he was aiming at, and in an instant a ghostly light flashed away, and the next second there was a loud bang in the distance, and the shockwave mixed with the debris and terror exploded, and there was an angry roar inside, and a strange force came with the roar, and he saw that the defenders on the sentry wall were all white.

"Sources of infection!"

Lero's tone was a little frightened, but also a little afraid, Lin Chen squinted and watched the gravel dust fall, revealing a large pit with a diameter of more than ten meters, and at the bottom of the pit that was three meters deep stood a humanoid monster only two meters tall covered in scales, and a faint aura of fear spread from under his feet.

This humanoid monster is not at all like the ugliness of the infected, it is obviously a monster, but it reveals a trace of dignity and elegance from head to toe, it looks like a nobleman, he looked at Lin Chen with a pair of red and bright pupils, and a smile appeared on his face:

"The Human Descendant!"

And Lin Chen was also surprised, on that source of infection, he sensed the breath of the same descendant, but not the same as himself, but the breath of another Tower of Eternity.

As the number of comings increased, the strength increased, and the understanding of the Tower of Eternity and the Void gradually increased, and what I knew in school was basically useless.

The information he knew before was only that there was only a human Tower of Eternity in the Void, but as his strength grew, especially the increase in the amount of information he obtained after worshipping the Mixed Yuan One Qi Sect, he knew that in the Infinite Void, there was not only one Tower of Eternity, but also other alien Eternal Towers.

I used to think that with the end of the Flood Shattering Era, all the immortals and demon gods disappeared, but now I know that they have not completely disappeared.

It's like reading a book, when you go to university, you will be surprised to find that the knowledge of the previous elementary or junior high school will be completely overturned in the university, and some of the previous theories will be wrong after the university.

But the truth is that these false theories can be applied to real life.

Some theories are correct for ordinary people, but for those elites whose knowledge is at the top of the human race, it is another set of knowledge theories, and the two are not in conflict because the levels are different.

You're welcome, Einstein and ordinary people are both human beings, but the realm of the two is completely different.

Well, it's too far, let's just say that now, after Lin Chen found out that the so-called source of infection on the opposite side was an alien race from another Tower of Eternity, he was not much surprised, but curious.

It was also the first time he had met the legendary Alien Descendant, and if he could, he would have liked to talk to them.

However, the reality does not allow it, because after seeing the unknown race descending, Lin Chen rarely received a task from the Tower of Eternity, killing the alien descender, and rewarding each one with one hundred eternal points.

Of course, he didn't pay attention to a hundred eternal points, but from this, it can be seen that the attitude of the Tower of Eternity towards foreign races is to kill when he sees it, and if he communicates with the other party in this case, he is afraid of .....

Well, the Tower of Eternity probably won't pay attention to such a trivial matter, he is afraid that the other party will cut it with a backhand.

He can receive this kind of task, and the other side is probably the same, they are naturally hostile, which can be seen from the way the infected source looks at him as if he sees a pile of walking points.

Lin Chen's neck turned and let out a series of crisp bone sounds, a sneer appeared on his face, he put away the bow, and then turned over a delicate sword in his hand, and gently pulled a cold sword flower at the tip of the sword.
