Apocalyptic starship

The Rubik's Cube quickly separated the soil and drilled into the ground. By detecting the soil, it locked the general direction of the tunnel and dug downwards. When it was about two hundred meters underground, it found the first mechanical soldier. Some kind of hard ore crushed the chest of the mechanical soldier. The energy device caused the death of the mechanical soldiers, and then the remains of more than thirty dead mechanical soldiers were discovered one after another. After continuing down, they finally found the injured and still alive mechanical soldiers. The high-end mechanical soldiers were safe and sound. The ordinary mechanical soldiers were severely damaged, and most of them were injured. The mechanical spiders used to dig holes were fine, because they ran to the feet of the high-end mechanical soldiers to avoid disaster the moment they collapsed. It turned out that their choice was very correct.

"Creator, we were ambushed. A large amount of high explosives were placed below. They are not the explosives of our mechanical army. The composition is different. Zombies will not do this. There may be someone else." A high-end mechanical soldier was in the collapsed narrow space. Said to the Rubik's Cube.

"We'll talk about it later. Take those who can move with you and those who can't. Bring the bodies of the dead soldiers with you. Let's go up."

"yes."

Except for being hit by the special hard metal ore in the cave, damaging and dying, the mechanical soldiers buried in the soil were fine. Through the information sharing Rubik's Cube, we can see the cause of the incident. Originally, a group of standard combat units entered the cave with standard tactics. Zombies were indeed found, but the level was not high. There was a dry underground river underground. The dark river led to nowhere. Just when the mechanical soldiers were about to throw a few scouts to draw the river map, the zombies used torches to ignite the explosives. , the result Rubik's Cube saw.

Following the temporary holes excavated by the Rubik's Cube, severely damaged mechanical soldiers climbed to the ground one by one. The transport helicopter landed. Rescue robots transported the damaged mechanical soldiers away or replaced parts on the spot. The remains of the dead were brought back to the factory to be refurbished...

The huge underground river, Rubik's Cube felt that the zombies absolutely did not want such a hidden underground activity place to fall into the hands of the mechanical army, so they used explosives to blow it up. There is no need to guess the source of the explosives. They must be the same group as the blasting mountains. The weird thing is how they secretly Transporting so much explosives into the southern part of the mountains.

Rubik's Cube dispatched a group of excavation robots to excavate the location of the city's underground rivers. At the same time, it sent satellites to investigate several countries near the northern part of the mountain range. High-altitude reconnaissance aircraft also cooperated with the satellites to search.

"If I knew which bastard dared to send zombie explosives, I would soak him in sulfuric acid for ten years!"

The damage to the mechanical army made Rubik's Cube very angry. While intensifying the search, it also intensified the attack on the zombies. The artillery troops moved forward, multiple temporary bases and field airports were established, and the railway lines were extended to the front line to transport ammunition supplies. Since If you dare to resist, then be prepared to face more severe attacks. Anyway, there is no need to pay taxes for ammunition manufacturing and metal mining.

After being ambushed in the cave, the mechanical army changed its program and set many new combat rules. It is no longer possible to use the cave to bury the mechanical army.

Mo Yaner was grounded, and if Ling had some free time, Ziyi could also take the opportunity to wait and sleep. The excavation team made rapid progress and opened up the river in both directions at noon the next day. This time, in order to prevent losses, a large number of aggressive mechanical insects were first used Searching for zombies and bombs, densely packed mechanical insects flew ten kilometers in two directions, but no zombies or explosives were found. The only information was that the underground river was very long and contained a strong smell of zombies.

Ordinary mechanical soldiers are easily damaged in the face of collapse, but high-end mechanical soldiers are not afraid of being buried by mud and rocks. Naturally, they become the main force in exploring underground rivers. Two teams of high-end mechanical soldiers search and advance on both sides of the river...

…………

The length of the cave was beyond the imagination of the mechanical army. Rubik's Cube focused all its energy on the direction leading to the huge mountain. Rubik's Cube suspected that explosives were smuggled from the north of the mountains to the zombies through this underground river. Along with the death scorpions and iron armor, there were fifty Two high-end mechanical soldiers headed north along the ancient river.

The river is very straight, and the Rubik's Cube can even fly underground with its mechanical army to speed up the journey. After flying for a few days, the Rubik's Cube guessed that it had arrived near the mountains, leaving five high-end mechanical soldiers to dig holes upwards to break through the ground, and continue to move forward with the rest of their men. .

What makes the Rubik's Cube strange is that the further north you go, the less zombie smell you get, until you can't find any trace of zombies at all. Why is this?

Why give up on such a hidden passage, most likely through a mountain range? Even if we can't pass through the mountains, placing explosives in the river will create a big gap. There is only one possibility. The front is very dangerous. It is so dangerous that even high-level zombies are not sure of safety, so the river can only be used with open eyes.

The Rubik's Cube stopped flying and landed on the ground, and a group of men behind it also stopped.

When the detection equipment was scanning the air in the ancient dry river, it was found that the air flow was flowing slightly and repeatedly, which meant that it moved forward and backward for a while. Death Scorpion and Iron Armor also discovered abnormalities.

"The change in airflow is somewhat similar to..."

Tie Jia seemed to have thought of something similar, and Death Scorpion followed.

"Like the breathing movement of the lungs of cellular organisms, the airflow moves in opposite directions with each inhalation."

The Rubik's Cube did not object to the possibility that Death Scorpion said. In the Shenwu Continent, in this world of cultivating immortals and demons, everything is possible. Behemoths have not been seen before. Many of the messy behemoths on the seabed cannot be named. Occasionally, they appear on land. A giant beast is normal, but the question is whether the other party likes to eat steel. Zombies don't dare to get close anyway. What if they get close and get eaten?

"Detection capability failed, send out a reconnaissance device!"

He took out the reconnaissance device and threw it out. The two small balls flapped their wings and flew forward quickly while scanning the river terrain. It was better to be careful in everything, otherwise, if you walk into the mouth of a giant beast, it would be bad.

Time passed slowly in the anxious waiting...

Suddenly, the three Transformers of the Cube looked at the depths of the river. The two reconnaissance devices just now were scrapped instantly. There was no attack and no one appeared. It just broke down suddenly. The Cube didn't believe that the reconnaissance devices he made would have mechanical failures at the same time. Software failure was even more impossible. The only possibility was that they were attacked by some powerful creatures.

"Should we... continue to release reconnaissance devices? Or mechanical insects." Tiejia asked.

"No need. No matter how many reconnaissance devices are sent, they will be destroyed. Our current geographical coordinates are... in front of the mountains?"

The Cube didn't expect that there was a tall mountain range less than ten kilometers above its head, and the place where the reconnaissance device just lost control was almost below the mountain range. What was there in the mountain? Just when the Cube was considering how to scout, a low voice suddenly sounded in the ancient river...

"Come here, I won't hurt you."
