As soon as Onno and the others entered the tunnel, Ya had already scanned the air environment in the tunnel, which was no different from the outdoors, and the environment here was relatively more suitable for human survival. The results of this detection also indicate that there should still be a life support system in operation in the city at the bottom of the lake.

As I walked along the tunnel, the walls of the tunnel around me became transparent. Through the transparent walls, Onno could clearly see a carriage, and the original colors of the carriage had been burned into darkness by the flames. As for the creatures in the carriage, they have all turned into dried corpses without exception, still maintaining the frightened look they had before they were alive. At the front of these carriages, a streamlined locomotive was overturned by something and lay on the tracks. However, there are still some electronic devices flashing inside, indicating that there is still energy running inside these things.

Passing through the transparent wall, Onno and the others finally walked out of the tunnel! It was already a ruin of high-rise buildings, but a large number of plants on the ground had grown very well, and some had even arched several large holes in the ground. The red foliage and shimmering red bioluminescent trunks make the city look eerie.

And in the very center of the city, that is where Onno and the others will go. The location of the red dot of light is in that place. Walking on this quiet and uninhabited street, Onno and the others still did not dare to relax their vigilance. After all, for thousands of years, no one knew what was going on here, and it was unknown if there were any threatening creatures inside.

Walking in this huge lake-bottom city, the strangest thing is that it should be dark, but there is a relatively bright light, and when you look up, the dome above the sky is shrouded in a layer of dark red "clouds". Although the eyes can see clearly, in this environment, what the eyes see is not necessarily completely safe. Because of this, a sonic weapon behind Onno was used as a special radar device to continuously shoot ultrasonic waves into the surroundings to build a map of the city and detect dangers around him.

As everyone gradually went deeper into the city, there were also a large number of scrapped vehicles here, and by chance you could see a relatively well-preserved one, Onno stepped forward to try to see if it could be started, but it turned out that this thing must have four hands to control, and Onno's two hands could not make this vehicle move!

Ono reluctantly stepped down from this looking streamlined vehicle, and reluctantly glanced at this vehicle that looked like the most luxurious sports car in Ono hometown, feeling a little pity. And as Onno stepped out of the vehicle, his hand inadvertently touched a button in the vehicle. Immediately after, the remnants of civilization resounded in this silent city!

The loud sirens of the vehicles almost deafened Onno's ears! The three camouflage soldiers turned on their sound shields and looked around very alertly, constantly searching for possible enemies using the devices on their armor and the eyes on the back of their heads.

Onno hurriedly re-entered the vehicle and began to look for the mechanism that sounded the alarm, so that he could close it and calm his ears. After some searching, Onno found a red light switch on the console of the vehicle and turned it off, which made the deafening sound disappear.

Onno turned off the alarm and re-emerged from the vehicle. It was discovered that the three camouflage soldiers were engrossed in patrolling back and forth, because just as Onno had just turned off the alarm, some dark shadows appeared around him that should not have appeared. These shadows hid in the shadows of the surrounding trees, hiding themselves well.

When Ono turned off the alarm, some of those dark shadows showed signs that they were about to attack Ono and the others! After receiving reports from the three camouflage soldiers, Onno Jeanja fired a powerful ultrasonic wave from the modified sonic weapon to "shock" the shadows to see what they were.

When Ya got Onno's order and was about to carry it out, he suddenly felt some tremors on the ground, and then he heard a strange sound from a distance, which was like a galloping horse, and gradually looked closer to the place where Onno and the others were.

As soon as Onno and the others acted, the black shadows hidden behind the trees all showed their appearance from their hiding places, they had the appearance of humans, but this humanoid was all made of things like tree branches, and they were also wearing layers of tattered cloth "cloaks", and they were holding some weapons that could fire a red bullet in their hands!

Although the flight speed of these bullets was very slow, and Onno could easily dodge the past, the number of these black shadows was somewhat beyond Onno's imagination, and those red bullets formed a dense net that forced Onno and the others to fire and destroy these branch-like humanoid monsters. It's just that there are a lot of these guys, and they always act in a stealthy form, which makes it difficult for Onno and others to lock down these guys.

Onno and the others could only fight and retreat to the downstairs of a building, and the four of them smashed the glass and hid in the building. At the same time, the monsters that made the sound of galloping horses also appeared! These monsters look like balls, but on top of them are a pair of rather thick and powerful limbs. Some of these spherical monsters also have some cold weapons in their "hands"! The sharp edges of those cold weapons sent a chill to Onno's heart.

After the four of them cautiously hid in the building, the spherical monsters didn't seem to have intelligence, just a group of monsters gathered together. So when Ono and the others disappeared, these spherical monsters began to fight with those "tree people"! The two sides fought for everything, and either the bulbous monsters' thick hands and feet tore the treemen apart, or the red bullets fired from the treemen's hands killed these spherical monsters on the spot.

Gradually, the corpses of the orb monsters disappeared, and the treemen with guns returned to the shadows of the trees by the roadside and disappeared. Ron Nuo and the others cautiously walked out of the building, and after observing the surroundings, they picked up a weapon used by this monster from next to one of the torn treemen and examined it carefully.

This weapon has the same tree-like appearance as those tree men, except that the dark red fluorescence on the muzzle of the black hole and the gun gives people an indescribable weirdness. As for the overall structure of the gun, it is basically the same as the way humans use it, which is to pull the trigger and then fire the bullet! Thinking of this, Onno looked at the dark red fluorescence, shook the gun, and heard the sound of liquid flowing inside, so he was basically sure that there should be bullets in this thing, which could be shot.

Then Onno found a place to raise the treeman's gun and pulled the trigger, only to hear a muffled "poof", the treeman's weapon did not fire the red slow-flying bullet, but a rather viscous liquid, but this liquid sprayed quite far!

"Whew!" The liquid splattered into the spot where Ronno had been targeted, where there was an abandoned vehicle, which was contaminated with the liquid and instantly corroded, emitting puffs of white smoke. "Hmph, does it look like it's still very easy to use?!" Unnor muttered to himself, shook the weapon vigorously, and after hearing the sound of liquid inside, he was sure that it should have a lot of ammunition left.

With a new weapon, Onno took it and started to move towards the red point of light again! But before the four of them could take two steps, they heard the sound of thousands of horses galloping again! Seeing this, the four of them hurriedly ran back to the hall of the building where they were before, looked for a hidden corner, and quietly poked their heads out to continue to observe the monster that made the sound of thousands of horses galloping.

It's still those ball-like monsters, but this time, in addition to the monsters with cold weapons, the other ball monsters are holding something that looks like guns! These gun-like objects have a streamlined shape and black color, giving them a sense of slaughter. As the orb monsters ran, they came to the nearest building to Onno, stopped in their tracks, and then out of the orb monsters came a floating orb monster, this monster was not like the other orb monsters!

The other orb monsters were covered in a kind of short gray hair, and this floating orb monster looked as if it had just been fished out of the water, wet, and some bloodshot could be clearly seen on it. After this floating ball monster floated out of the many ball monsters, it didn't know that it was in a hurry and just floated quietly.

"Click!" When Ono peeked at this monster, he accidentally crushed a piece of wall in front of him! If this sound would not have been possible in the usual downtown area, but now in the middle of a quiet city, it is like a poor sheep falling into a pack of wolves.

After the sound came out, the floating ball monster turned around for the first time, and it was only when Onno and the others saw clearly that this floating ball monster was actually a huge eye! The unusually evil pupils of this eye stared at the building where Onno and the others were. Then I heard the whole body of the eyeball tremble, and let out a terrifying tremor, and those ball monsters rushed towards the place where Onno was like crazy!

As the monsters rushed, they also let out bursts of terrifying roars, and there was a feeling of ten thousand people charging in ancient wars! The monsters waved the cold weapons in their hands and rushed to the building frantically, and when Onno saw this, the weapon in his hand fired, and the red liquid that sprayed out quickly covered a ball of monsters!

The orb monster covered in red liquid did not corrode, but its round body suddenly exploded like a mushroom full of spores! A thick pink fog instantly enveloped the entire hall of the building! The orb monsters that came into contact with the pink fog fell to the ground in agony, their gray hairy bodies splitting apart, and a new tree man stood up from the corpse!

Seeing this scene, Onno and the others were stunned, especially Onno, he looked at the weapon in his hand in disbelief, he didn't expect that this weapon actually had such a function. But when Onno was even more surprised before he arrived, the pink fog in the hall disappeared, and more ball monsters rushed up with the newborn treemen with their teeth and claws.

Onno and the others ran all the way to the building, and finally got stuck in a corridor! In this somewhat narrow corridor, Ono no longer dared to use this weapon that could spawn tree people. The sonic weapon behind him was activated, and the camouflage soldiers began to bombard non-stop.

The number of orb monsters seemed to be endless, and everyone resisted for a full twenty minutes without seeing the number of these orb monsters decay. And their energy must be regenerated for a certain amount of time due to continuous firing! At this critical moment, the ears of Onno and the others heard the unique roar of the aircraft and the sound of a huge cannon!

The light above Onno's consciousness brightened, and when he looked up, he found that it was a flying machine with a picture of a toothless beast painted on it, and several people with three eyes and four hands were holding weapons to help Onno and the others clean up all those orb monsters......
