As dawn approached, a large number of unmanned aerial vehicles appeared in the sky above Iron Blood City. The accident in the Shuo Rat Lab made the management of Iron Blood City very angry, and immediately blocked all the passages out of the city, and sent a large number of military police to carry out an indiscriminate dragnet investigation with the Shuo Rat Laboratory as the center. At the same time, the mercenaries outside the city also received a sternly worded warning, telling the mercenaries not to cause trouble in the last two days.

There are micro-robot pathfinders obtained from special forces such as Blood Wolf, and Zuo Zhe and Ruiya find several trigger bombs planted on the retreat road in advance along the way. After all, the retreat plan was obtained from the blood wolf, and Zuo Zhe's retreat route overlapped awkwardly with the black wolf who left early. Fortunately, the black wolf retreated ahead of Zuo Zhe, otherwise the two would have been able to fight in the spider-web-like underground water web. It's really hard to say who will be able to beat who at that time. If it is fought in too narrow a place, the war mecha loaded by Zuo Zhe may not be able to exert much combat power. After all, an underground river is not like an underground base, and the rock wall can easily collapse under the erosion of the water.

It is possible for a mech warrior piloting a solo mech to be killed by this preset trigger bomb, but Zuo Zhe will not. The loaded war mecha gives Zuo Zhe stronger defense, and even if it is affected by the explosion, it will not be too much of a problem. However, since the trigger bombs planted had been discovered in advance, Zuo Zhe would naturally go around. It's really unavoidable, and it can be detonated in advance. Even if an explosion collapses an underground waterway, Zuo Zhe can use the excavation equipment to quickly dig a passage.

After some tossing, Zuo Zhe finally rushed out of the underground river with a black rumbling rumbling. Crawling out of the laxly defended sewage treatment plant and hypnotizing it amid the shouts of the night workers at the sewage treatment plant, Zuo Zhe took a wide windbreaker in the duty room of the professional employees. And just when Zuo Zhe wanted to delete the video footage of this time, Zuo Zhe found that the video footage of the previous period had been deleted. When the poor treatment plant night worker woke up from hypnosis, he could never have imagined that he had been hypnotized twice in a row during the hours he had been on duty tonight.

Under the cover of a wide trench coat, Zuo Zhe, wearing a hood, dodged the street corners where there were police soldiers set up along the way. Because the sewage treatment plant is already a short distance from the laboratory of the rats, there are still a few street corners around that do not have military and police cards. Along these unchecked, Zuo Zhe quickly walked away in the dark night before dawn. Although the direction is in the direction of the city center, at this stage, the inspection in the direction of the suburbs is significantly stricter, and it is safer to retreat in the opposite direction.

Well, it's not very safe to retreat in the opposite direction.

In the sky, many ultra-small unmanned aerial vehicles hidden in the night locked Zuo Zhe on the ground with suspicious appearances, landed not far in front of Zuo Zhe, and issued an unquestionable order, ordering Zuo Zhe to immediately take off his hood and be inspected.

Zuo Zhe, who was seriously inexperienced, did not expect the danger to come from the top of his head. And Ruiya, who should have been aware of the danger in advance, was very tired because she hadn't slept all night. Coupled with the fact that the danger had passed, Ruiya fell into a drowsy situation in the soft cockpit of the war mecha, which was extremely suitable for sleeping, ignoring the danger that might come from overhead.

"I'm exposed!" The body stopped in place, Zuo Zhe only felt very uncomfortable, as if he was exposed to the spotlight of the stage without wearing anything, and he really wanted to find a hole to get into.

At this moment, Zuo Zhe suddenly began to miss the sense of security hidden under the surface before. Although the underground is cramped, at least there is no need to worry about threats overhead. Nima, I would have known it earlier......

Facing the micro-flying machine suspended ten meters in front of him, Zuo Zhe wanted to smash it with a fist. However, after Zuo Zhe realized that the danger was coming from above his head, Ruiya, who woke up from his drowsiness, told Zuo Zhe the cruel reality. Under the radar feedback of the war mecha, Zuo Zhe found that there was definitely more than one radar in the sky, not even dozens and hundreds! Judging from the communication signals between these micro drones, these micro drones are still networked with each other!

Resisting the urge to take out the excavation equipment and dig out a hole in the ground to run, Zuo Zhe forcibly suppressed the idea of smashing the drone with one punch, and finally chose to launch a telekinesis control on it!

Under the control of Zuo Zhe's telekinesis, this flying machine flew quickly in the direction of Zuo Zhe in Zuo Zhe's scream! The basin-sized flying machine crashed into Zuo Zhe's body at once, directly knocking Zuo Zhe into the "faint"!

"Aircraft 1566 malfunctioned, and Aircraft 1567 was immediately replaced. Notify the officers on duty at the nearest checkpoint to go to the scene to determine the identity of the injured. If there is no problem with the identity of the injured person, the injured person will be sent to the nearest hospital, and the logistics department will check the cause of the failure of the aircraft. "The control center, the first time there was a new control directive issued out, was split into several parts by different departments to jointly implement.

Dozens of seconds later, a single mecha with a standard coating of a police mecha quickly arrived at Zuo Zhe's location and came to confirm Zuo Zhe's identity. Only when the mecha warrior confirms Zuo Zhe's identity, the nearest hospital ambulance will take Zuo Zhe to the hospital for treatment.

There was no problem with the rigorous plan, and under the monitoring of the unmanned aerial vehicles that filled the positions in the sky in time, once Zuo Zhe had any abnormal movements, they would be captured by the aerial vehicles in the sky.

However, this kind of rigorous coping is not suitable for those who are very rare in the crowd.
