"Anomalous tremors detected!" Just as the python-like monster was rapidly approaching, a member of the Thunderstorm Mercenary Regiment in the underground base immediately detected the source of the epicenter.

"Leave it alone, keep moving forward!" Thunder Tiger gave an order, and the Thunderstorm Mercenary Regiment advanced again. Just replenished with ammunition and energy, the combat effectiveness of the Thunderstorm Mercenary Group has been restored, and the long-lasting combat effectiveness is also very strong. Therefore, Lei Hu is not worried about the back road being blocked. This strategy of the monster means that the monster's attack on the survivors of the underground base has been weakened.

It's just that just as the Thunderstorm Mercenary Group entered a narrow corridor, the camouflaged walls on both sides of the corridor that were as similar to the walls suddenly came to life, quickly filling the entire passage like explosive dust!

"Flame Spray!" The sudden danger caught the Thunderstorm mercenaries off guard. However, because it was only a matter of consciousness, the mercenary robots of the Thunderstorm Mercenary Group were just panicked. With Thunder Tiger's order, the mercenary robots scattered all over the team quickly took out the flamethrower and sprayed the blazing flames towards the roof of the corridor! Don't spray flames at the walls on either side because you are worried that the flames that bounce back will directly burn your own mercenary robots. Spraying the overhead canopy will also have the effect of burning the entire channel. Dust or something is the easiest to ignite! Even the dust is a tiny piece of metal that burns under the flamethrower flames at high temperatures!

But the flamethrower didn't work as well as expected, as the oxygen in the tunnel was quickly depleted! When the oxygen is exhausted, no matter how high the air temperature is, it is difficult for the dust in the air to burn.

"Shoot a low-power compressed air cannon!" After running out of oxygen, Lei Hu ordered again. Dealing with a large number of small monsters, the compressed air cannon with less energy consumption is an effective way to deal with it. After a rapid sound of pumping air, a series of low-power compressed air cannons with a power equal to none for the mercenary robot were launched, violently vibrating the monster particles that were secreting strong acid attached to the mercenary robot.

"Take the squad as a unit and quickly pass through this corridor!" Using the compressed air cannon to hit the teammate in front of him, dispersing most of the monster particles adhered to his teammate's body, Lei Hu ordered in the communicator.

"Captain, the robot is seriously corroded, and those monster particles are infiltrating into the robot!" One of his squad leaders exclaimed.

"Rush out first!" Shocked, Lei Hu still insisted on his previous order. Because the robots of the Consciousness Advent are free, Thunder Tiger can't expect these robots to be high-end at all. But even for the general public, the external armor of these robots can't be corroded so easily! After all, acid corrosion is just a chemical reaction, and for those superalloy armor that are stable and closely arranged, strong acids have very limited corrosion ability. What's more, these robots are also coated with a special acid-resistant enamel protective layer on the outside!

By the time the Thunderstorm Mercenary Group broke out of the dust range of the corridor, three mercenary robots had already lost contact with the team. As for the mercenary robot that broke out of the tunnel dust, the body did not suffer much corrosion.

"It's targeted against corrosion!" Cleaning up the residual dust from the robot's body, Thunder Tiger finally realized the monster's purpose. But why would the monster do it? Do you just want to concentrate your firepower to break them one by one?

Outside the underground base, Tang Chengyi, who had been observing the situation below with a mechanical gecko, received a request for help from the Thunderstorm Mercenary Group, "Come and save us, our Thunderstorm Mercenary Group is dying!" ”

"I see." Wu Tian, who was hiding on the side, finally understood all this after receiving a request for help from Tang Chengyi below. Whether it is the Thunderstorm Mercenary Group or the Huaxia Mercenary Group, they all have to obey Wu Tian's command and orders. It is precisely because of this that Wu Tian has the right to monitor all the information exchanges between the two mercenary groups in real time because of his higher authority! And before, Lei Hu, the leader of the Thunderstorm Mercenary Regiment, did not send a rescue request to the top at all! And if it was only the members of the Thunderstorm Mercenary Group who sent out a request for help, they could only send a request for help to the Thunderstorm Mercenary Group, but not to the Huaxia Mercenary Group!

Since it is very likely that the person who sent out the request for help was a monster, the request for help that Wu Tian received from the deepest part of the base before would most likely be a trap set by the monster!

Seeing that the Huaxia mercenary group was about to enter the base to rescue, Wu Tian couldn't sit still anymore. The alien that blends in with the surrounding environment quickly turns into a striking red warning color, and Wu Tian, who is usually attached to the wall with a screensaver, immediately attracted the attention of almost all the mercenaries of the Huaxia Mercenary Group! Almost at the same time, all the mercenaries aimed their guns at the liquid gold mecha where Wu Tian was!

"I am a foreseeer." Wu Tian's voice came into the robot where Tang Chengyi's consciousness was. hurriedly lowered the muzzle, and Tang Chengyi hurriedly asked the members to lower the muzzle.

Under the surprised gazes of the group members, Tang Chengyi looked at the liquid gold mecha where Wu Tian's consciousness was very envious, and asked in a respectful tone, "Mr. Foreseeer, I don't know what you command?" "In the previous battle to usurp the interstellar aircraft carrier, Tang Chengyi saw Wu Tian's ability to calculate with his own eyes, and almost fought a bloodless battle against an interstellar battleship! Although the main contributor is the "Conqueror" Demon Emperor, the role played by this wise man in front of him is equally crucial!

"There's probably a trap down here, and the so-called survivors are likely to have been killed." Wu Tian said.

"But the sudden mission issued by the Lord God?" Tang Chengyi said without saying anything. If the survivors below are dead, then why would the Lord God issue a mission for the purpose of saving the survivors?

Up to now, although Tang Chengyi has faintly felt that the main god space is not like the one in the network, he still has twelve points of trust in the mysterious "main god". If there was no main god, Tang Chengyi would have died in the near future because of terminal cancer! It is precisely because of the main god that Tang Chengyi not only snatched back a life from the hands of the disease, but also felt much younger!

"Although there is no problem with the tasks issued by the main god, there are possible traps hidden in some sudden main god missions." Of course, Wu Tian couldn't attack the image of the main god in the hearts of all the adventurers, but he only gave a slight hint.

"Why do you set traps in missions?" Tang Chengyi was shocked by Wu Tian's words, and hurriedly asked.

"No one knows the exact answer, but I guess it's a test of our intellect set by the Lord God. The Lord God requires us to improve not only in combat effectiveness, but also in intelligence. Wu Tian replied.

"But if we don't complete the mission, we will suffer a high penalty for failing the mission, so should we go down?" Tang Chengyi asked again.

"As long as the task in front of you is successfully solved, the conditions for the completion of the unexpected task will most likely change." Wu Tian explained.

It wasn't until Wu Tian explained everything that Tang Chengyi and the other mercenaries breathed a sigh of relief, as long as it wasn't a mission that was bound to fail.

"Mr. Foreseeer, are you here for this sudden mission?" Tang Chengyi asked in an earnest tone.

"That's right, I need your help to deal with the monsters below."

Under the leadership of Wu Tian, Tang Chengyi led twenty elite mercenary robots to rush towards the base with Wu Tian. Along the way, the mercenaries of the Huaxia Mercenary Regiment also maintained the necessary patrols and vigilance to ensure that they could detect the danger at the first time, rather than waiting for the danger to break out before reacting.

Along the underground entrance, which was much wider than the entrance of the subway station, Wu Tian's figure disappeared again from the field of vision of Tang Chengyi and the other twenty mercenaries, stealthily sneaking in front of Tang Chengyi and the other mercenary robots.

Just when Wu Tian took Tang Chengyi and other mercenary robots into the underground base of the base, the three mercenary robots who had lost contact with the Thunderstorm Mercenary Group had already turned into monsters, wrapped in clumps of viscous substance, and hidden in a space that appeared at the corner of a corridor. If you look at it from the outside, the walls of this corridor are very smooth, and there is no sign of entrance or exit. Even the architectural drawings of the underground base do not indicate the entrance to this place. However, under the corrosive infiltration of monsters, the secret passages opened up from the underground have connected the multi-layered space of the underground base. Like a spider's web!

However, for Wu Tian, the moment the three missing members of the Thunderstorm Mercenary Group sent a request for help to the Huaxia Mercenary Group, the general intention of the monster was already known to Wu Tian. And with the emergence of the new ability of the demon virus, a new crisis has also emerged. The demonic virus, which was originally confined to the Earth Star, may even spread to the entire galaxy! In order to determine the magnitude of this possibility, Wu Tian had to come down and investigate!

Sneaking silently, Wu Tian always kept an eye out for any abnormalities that might occur around him. However, it seems that the scale of Wu Tian and his party is not small, and there are mercenary robots in the rear to ensure the way out, and the demon monster did not immediately attack, but launched a second wave of attacks on the thunderstorm mercenary group deeper in the base!

At Wu Tian's prompting, Tang Chengyi and other mercenary robots took the initiative to turn on the equipped flaw detector to detect possible holes or cracks in the wall. In this way, along the way, breakthroughs that may be used by monsters have been found, and ventilation pipes and drainage pipes have also been specially marked, but, as the mercenaries continue to advance underground, the mercenaries' mood has become heavier and heavier. Because this underground base seems to have been corroded to the core, cracks and holes are almost everywhere! If it weren't for the fact that these gaps and holes were deliberately avoided by the load-bearing beams, this underground base would have collapsed long ago!
