After a pause, Lin Hai nodded and said to the drone controller, "Go back!" There are other collection vehicles around, so you can re-track them later! "It's more important to find a way to isolate the erosion of crystals like a virus than to find the location of the current base of the Sijing people. Pen & Fun & Pavilion www.biquge.info

Under the operation of the controller, the drone silently adjusted its direction in the air, returned to the previous route, and the ultra-clear camera scanned the target on the ground again.

"That's it." Sun Dahai walked to the drone controller in two steps, patted the other party, and then pointed to a corner of the main screen representing the drone's field of vision and said, "Enlarge that." ”

Another screen immediately showed the so-called crystal incorrosible object that Sun Dahai pointed out, which was indeed a metal jar, a huge metal jar.

"This thing looks like the tank part of a tanker." Cohen took one look at the thing and spoke.

"Look around this thing." Sun Dahai continued to instruct the drone controller, "Find out if there is a part of the front of the car." ”

"That should be it." The controller pointed to a crystal crystal block that looked a little square and said, "The front of the car should have been completely transformed." ”

"Everyone," Sun Dahai nodded, then turned to face everyone, and then pointed to the big metal jar and said, "Look, this jar, the front of the car has been completely crystallized, but the jar itself has not been eroded by crystals, maybe this is a way for us to find a way to resist transformation." ”

"Aren't these tanks usually just ordinary steel used?" Admiral Hammer looked at Lin Hai, "These materials shouldn't be able to resist the transformation and erosion of crystals, right?" ”

"That's right." Lin Hai agreed, "But this thing is in front of us, and it does not show any signs of erosion, so there must be some reason why ordinary steel has not been eroded." If the reason has nothing to do with the material, perhaps it has something to do with the contents of the jar. ”

Lin Hai glanced at the screen, and then said: "Look at the surface of the can, whether there is anything printed on it that proves what is in the can." ”

"It's liquid nitrogen." Without waiting for the controller to operate the drone to search for the tank, Cohen said, "There are several tankers transporting liquid nitrogen in the research base, and I am very impressed to see them every day these days. ”

"Liquid nitrogen?" Everyone turned their eyes away from Cohen back to the screen, where a snowflake-like low temperature warning mark had appeared, and the drone had found the mark on the tank.

"There are traces of liquid nitrogen leakage." The controller said while scanning the tank with the detectors equipped on various drones, "There are no obvious signs of damage on the surface, but the temperature of the tank is about minus 60C, which should be due to the rupture of the inner tank and the liquid nitrogen coming into contact with the tank shell." ”

"I just don't know how long the breakage has occurred before the temperature has reached the current temperature." Lin Hai said, "But it seems that those crystals seem to have some way to deal with ultra-low temperatures?" Perhaps we could consider treating the vehicle shell at ultra-low temperatures to prevent crystallization erosion. ”

"The destructive power of ultra-low temperature on the vehicle is not small, and the mechanism of the vehicle components will deteriorate." Cohen hurriedly said, "You can't let all the vehicles you send in become disposable, right?" ”

"I didn't say that the existing equipment should be directly frozen." After Lin Hai replied to him, he looked at Sun Dahai, "What do you think?" ”

"I haven't tested it, I don't know, but I can give it a try." Sun Dahai replied, "It's just that we don't have ready-made tools in our hands to carry out this modification, and we may need to study some equipment in the base." ”

"Is there any problem with borrowing your stuff?" Lin Hai turned his gaze to Cohen again.

"No problem, but my people have to watch it live, too."

After thinking about it, Yu Guang saw Sun Dahai nodding slightly, and understood that this modification would not reveal any advanced technology from them, so he also agreed and said, "Yes." Your people can participate in modding activities. However, since this is only testing, we will not modify many vehicles in the early stage, and we will not directly send humans to drive the vehicles for testing, but will need your robots to drive them. ”

"I understand." Thinking of what those rebel captives said about the fate of humans coming into contact with crystallized crystals, Cohen couldn't help but shudder, and then simply agreed to this request, "There are still some robots in the research base, and we can even organize a team composed of all robots to go to New York to test this aspect." ”

"It doesn't have to be that far." Lin Hai casually pointed to the map and said, "The crystal erosion test will not begin until we recover all the towns from New Haven to New York, and there are seven towns on the map alone, and five more on the flanks, and if we don't recapture them all, we can only cross Long Island Bay to bring equipment and personnel to New York." ”

"Well, I'm in a bit of a hurry." Cohen shrugged his shoulders and said unconcernedly, "I've had enough of this life, and I really want to end it immediately and return to my old life of being drunk and gold-addicted." ”

"Don't mind, he's been like this since he was a kid." Admiral Hammer said to Lin Hai's surprise.

"Have the drone keep an eye on a Sijing collection vehicle, and now we need it to take us to their base." Ignoring the small talk between Lin Hai and Hammer and the others, after learning that the low temperature might corrode the defense crystal crystals, Sun Dahai continued to command the drone controller to carry out reconnaissance missions.

In New York City, the drones hovering between several tall buildings immediately turned around again and flew towards a trilobite van that had been harvested with crystals, which would lead the drone directly to their base.

But when the drone was at an altitude of three or four hundred meters, hiding between the floors and tracking the collection vehicle all the way, a red flash suddenly appeared on the ground between the two tall buildings! In a world where there is no light, this flash of light is quite noticeable!

"Oops!" The controller's instinctive wrist moved, and the drone also deviated to the side, and a red beam of light passed by the side of the drone fuselage and disappeared into the night sky!

"The drone has been discovered!" Lin Hai frowned and said, "Quickly rise into the air, widen the distance from the ground anti-aircraft fire of the Sijing people, the effective range of those things is limited, after the distance is opened, the plasma will naturally dissipate after flying a certain distance!"
