Fantasy Game: Infinite City

"Boom!"

"boom!"

"Ho~~!"

Three different sounds were heard in the heavy rain outside the cave. The first was thunder that sounded from time to time. The falling thunder briefly illuminated the space outside the cave, and one could see a group of monsters moving like a tide, causing the ground to shake violently.

The second sound was some distance away from the cave. It was the sound of an explosion, and it was also approaching the cave. As the sound of the explosion rang out again, the soldiers inside the cave finally heard clearly that it was not the sound of a single explosion, but a series of explosions with very short intervals, very similar to the sound of a cluster bombing.

The third sound was the deafening roar coming from the group of monsters. They sounded angry, but there seemed to be some other emotions mixed in.

As the group of monsters gradually approached, Heidi gave an order, and all the soldiers, including herself, turned on the optical camouflage on the auxiliary armor. They remained still behind the fortifications they had built to avoid making any sound as much as possible.

"Boom boom boom~!"

A series of explosions sounded again. This time the sound of the explosion was very clear, and one could even hear the screams of many monsters before they died. After a moment, the noisy sound gradually quieted down.

However, the soldiers' tense nerves did not relax. They waited quietly because the group of monsters in the rainstorm were still approaching the cave.

Heidi observed the situation outside through the night vision function of the helmet. She found that the monsters seemed to have stopped moving forward and were wandering in place, with their heads facing the direction of the explosion.

At this time, a wave of heat blew into the cave from the rainstorm, bringing fresh air from outside, mixed with some strange smells, which seemed to be the smell of something burning. In the rainstorm far outside the cave, something lit up like a lighthouse on the dark sea, the light kept pulsing, and more heat waves were blown into the cave. But soon, the spread of the heat wave stopped, and the light in the distance also stopped where it was.

A glimmer of hope surged in Heidi's heart. She guessed that it might be a friendly attack. However, no one dared to act rashly for fear of attracting the attention of the monster. The soldiers did not rush to send a signal, but decided to wait a little longer and observe the changes in the situation.

When she saw that the light in the distance was no longer flickering but stayed in place, Heidi suddenly thought of something. She removed the optical camouflage on her arms, made a few gestures, and then hid in the optical camouflage again. After seeing her gestures, the air in the cave refracted abnormally several times. It was two soldiers who began to move under the cover of optical camouflage.

They came to the temporary signal group, quietly dismantled the signal group, and quietly returned to the location of the exploration team below through the hole at the bottom of the cave. After relaying the above information to the team, they re-established the communication signal group on this floor. After the assembly was completed, they immediately began to contact the rescue personnel.

"This is Exploration Team β! Rescue Team, can you hear me? This is Exploration Team β! Rescue Team, can you hear me?"

“Sizzle…Sizzle…”

There was a lot of interference coming from the other side of the signal group, which made the team leader a little frustrated, but he still did not give up hope and continued to call the rescue team.

"This is exploration..."

"Zizi... Exploration Team β, this is the rescue team. Your communication is very clear, indicating your location. There are a lot of monsters outside, and I can't accurately determine your specific location."

"Alas!"

Hearing the clear voice coming back from the other side, everyone in the exploration team breathed a sigh of relief and couldn't help but cheer. The person in charge couldn't help but shout along, but he quickly recovered his composure.

"Rescue team, we are located in a collapsed building, about 20 meters above the ground. Below us is a huge shaft consisting of multiple collapsed rooms. Above us is a cave connected to our location. We have sent you the structural diagram of the area we passed, including the cave. Inside the cave, our armed personnel are defending the entrance. Our specific coordinates are..."

The person in charge quickly sent the specific coordinates of the exploration team to the rescue team. After receiving the information, the rescue team heard more explosions through the communication group. However, based on the coordinates that were finally displayed on the communication group, the person in charge discovered that the rescue team's moving route did not go directly to the location of the cave, but instead left in the opposite direction.

"Let the... ziz... ziz... retreat... ziz... the specific... number of people... ziz..."

As the distance between them increased, the communication was disrupted again, but the person in charge immediately understood what the rescue team was going to do and immediately responded to the rescue team.

"Exploration Team β includes combatants, a total of 57 people remaining. Repeat! A total of 57 people remaining!"

"Collect... sizzle... sizzle...! 10 minutes... sizzle... sizzle... Stay... sizzle... Defensive! sizzle... sizzle... Monsters... sizzle... Group... sizzle... Go!"

Soon, it seemed that the communication distance had reached its limit, and the communication with the rescue team was disconnected again. After the communication ended, the person in charge issued an order, and a soldier returned to the upper cave to inform the remaining soldiers to withdraw to the safe lower space. Using the optical camouflage on the auxiliary armor, more than a dozen soldiers guarding the upper cave, including Heidi, were all evacuated safely and returned to the safe area below.

"What did the rescue team say?" Heidi came to the person in charge and asked.

"Let our people evacuate the cave and wait to build defenses. I have reported the remaining number of people in the team. The rescue team should be looking for a vehicle or something similar that can allow us to move in the highly corrosive rainstorm. At the same time, they are also leading the monsters away. Let us wait for ten minutes, but the communication is severely interfered, so he may mean at least ten minutes."

Through the cooperation of the communication group and the scanner, the exploration team observed that the group of monsters on the detector was moving to the other side, just above the previous pool of water where the monsters spawned.

"Boom!"

"Clang!"

Continuous explosions sounded, and the entire area of ​​the building buried underground began to shake. Some damaged building debris fell from above and hit the ground at the bottom through the huge hole below.

"Pfft!"

When the debris hit the bottom, there was a loud splash. It seemed that the bottom layer had been filled with backflowing rainwater. Now there was no possibility for the exploration team to return the same way they came.

"If this huge rainstorm continues, in two hours, these highly corrosive rainwater will rise to the floor below us, and in three hours it will flood our floor. I hope the rescue team can get back in time."

Unfortunately, things did not go as planned. An hour later.

The accumulated water below was rising higher and higher, and now the water surface could be clearly observed with the naked eye. To make matters worse, bad noises were also coming from the cave above.

“Crack…Crack…Crack!!”

"Boom... Plop!"

Perhaps because of the erosion of heavy rain, the cave above suddenly collapsed, and some huge rocks blocked the cave entrance on the bottom floor. Moreover, due to the structural changes caused by the collapse, the pouring rain outside also flowed down the slope inside the cave. Fortunately, the huge rocks blocking the bottom of the cave changed direction, and the heavy rain flowed directly down along the big hole below.

"The good news is that we don't have to worry about monsters now. The bad news is that the water level in the pond is rising faster. In about fifty minutes, we will be swallowed by this highly corrosive water."

After analyzing the changing terrain, the researchers holding the scanner told the person in charge and the soldiers about the difficulties they were facing. After relaying the situation, they sat down on the ground in frustration.

"Cheer up! Don't give up, we still have a chance! Rescue workers will be here soon!"

Heidi and the person in charge calmed the other members of the exploration team while ordering the remaining soldiers to find other safe locations.

Time passed by minute by minute, and the rising water was less than ten meters away from the exploration team's location. The soldiers quietly conveyed the worst news to Heidi and the person in charge.

There isn't any other safe space around.

"Although we have destroyed the huge rocks blocking the road, the cave has collapsed. That place is completely exposed to the rainstorm. Several of our brothers were almost caught in it."

"Boom!"

The bright light of lightning came from the cave where there was no cover. The person in charge sighed and looked up there. But at this moment, the outline of something appeared in his eyes and was rapidly enlarging.

"What is that...!"

"Bang! BANG! BANG!" The loud noise of heavy metal colliding with rock instantly attracted the attention of all members of the exploration team. The cave that could occasionally emit lightning suddenly lost all light. A large metal object smashed into the cave, blocking the light. At the same time, because it blocked the cave entrance, the speed at which the accumulated water rose also slowed down.

“Dang…dang…dang!”

“Shhh~Shhh!!”

Inside the metal structure, there was the sound of boots stepping on the metal floor. Judging from the sound, it should be a sturdy and tall humanoid creature. The completely enclosed metal structure had some noises coming from the bottom that tilted downwards. It seemed that the metal was being melted by something. Looking at the red outline, it should be someone making a door.

"Bang!"

As the "door" was kicked away and embedded in the opposite wall, a two-meter-tall muscular man with a wet shirt wrapped around his suite walked out of the "door". When he appeared in front of the exploration team, the communication group also rang at the same time.

"A complete communication loop has been established. Multiple signal amplifiers have been detected and are being adapted... The adaptation was successful and the communication distance has been increased."

The person in charge and Heidi came to the edge of the hole, looked at the man above, and asked tentatively,

"Rescue team?"

"Exploration Team Beta?"

The person in charge nodded, and then the exploration team fell into a brief silence. A few seconds later, cheers broke out among the crowd.

"saved!"

"I won't die!"

"Boom!"

The members of the rescue team fell from a great height and walked into the survivors' camp from the darkness. The emergency searchlight finally illuminated his body, revealing his appearance. It was Han Zu, who was entrusted by the research center to rescue the survivors.

"They're so excited just because they saw me?"

Han Zu took off his wet shirt from the suite and threw it on the steel bars sticking out from the edge of the hole. He shook off the highly corrosive rain on his hands, walked up to the person in charge and shook hands with him.

"The fact that the headquarters only sent one rescuer shows that they have great confidence in your ability to rescue everyone. We all believe in the headquarters' judgment!"

After chatting with the person in charge for a while, Han Zu told them how to leave later and that he was currently lacking some necessary materials and needed to find them first. The team leader also informed Han Zu that the accumulated water was about to rise to a dangerous height.

"This is easy. According to my observations on the ground, the other side of this space is also a huge separated space. As long as we divert the accumulated water there, we can buy at least five hours of safety time."

"But with the equipment we currently carry, we can't destroy the wall..."

"Don't worry about this, I'll do it."

As soon as he finished speaking, the person in charge, Heidi, and several soldiers surrounding Han Zu discovered that there were six large holes on Han Zu's left and right shoulders. Han Zu pushed through the crowd and came to the edge of the collapsed hole, looking for something.

After locking a position, the people around discovered that twelve bone objects that looked very similar to rocket warheads grew rapidly from the big hole in Han Zu's shoulder, and then suddenly flew up, just like real rockets, and quickly slammed into the opposite wall with dark green tail flames.

"Boom boom boom boom!!"

Several huge holes were instantly blasted open on the opposite wall dozens of meters away, which were connected to each other to form a huge gap. A large amount of accumulated water was drained from the gap to the space next door. The accumulated water instantly dropped by one third, and the rising speed of the water also slowed down.

Although they had expected that the people who came to rescue them would be very powerful, they were still shocked after seeing the methods used by Han Zu, the humanoid weapon.

"In this case, there should be enough time. I need to find at least two giant iron chains that are strong enough and can resist corrosion. In addition, I plan to bring back two monster eggs, which may be helpful for your research."

After saying that, Han Zu turned around and prepared to jump directly into the pool of water below, but before he left, someone stopped her.

"Can you... take me with you? I want to retrieve the nameplates of my companions. They shouldn't be forgotten in this place."

Heidi called out to Han Zu who was about to leave, but soon lowered her head, perhaps because she noticed that her request seemed a little excessive.

"Okay, but have you ever driven a mecha?"

"Huh? What.. Oooooohhhh!!!!"

Han Zu's body suddenly split open and stretched out a large number of tentacles, instantly pulling Heidi into his body. As his body quickly returned to its original shape, Heidi was pulled into Han Zu's body, and it was completely invisible from the outside.

"Oh, sorry, I forgot to leave you a view."

The muscles on Han Zu's chest moved rapidly, revealing the observation position of Heidi's helmet.

"Is your helmet able to resist corrosion?"

"Huh? Oh, yes!"

The sudden change scared everyone around, but fortunately, this powerful and somewhat weird person was indeed on their side.

"Continue to rest. Although I have lured away the cluster of monsters before, you still have to be careful."

"Okay, you should also be careful Heidi and don't cause trouble for the rescuers."

"clear."

Han Zu simply signaled to everyone, then turned around and jumped, falling directly into the water. Although Heidi could not move her limbs, she was able to move her head and carefully felt this magical but weird feeling.

"It really feels like driving a mecha..."

After explaining to Han Zu the location where the soldiers had died, Han Zu used the high temperature to melt the metal buildings and rocks in a straight line, and swam quickly in the direction Heidi said.
