Chu Shi believed it was not the right time to make contact with the aliens from outer space. Su Han readily agreed.
At this point, Chu Shi continued to check some data.
After finishing the checks, Chu Shi saw some figures and his face showed surprise as he said, "We've lost contact with a Globalized Type 3 drone."
Su Han asked, "Signal lost? Where did it go missing? I recall all the Globalized Type 3 drones entered high-speed mode yesterday. Can they still be shot down in that mode?"
Chu Shi replied, "It disappeared in the northwest direction, between 1,500 and 1,900 kilometers away."
Su Han recalled the signal transmission range of the Globalized Type 3 drones and asked curiously, "The signal transmission range of the Globalized Type 3 drones is only a few tens of kilometers, right? How can we know it disappeared over 1,500 kilometers away?"
Chu Shi explained, "The Globalized Type 3 drones transmit video and audio information over tens of kilometers. In addition to that, they are equipped with shortwave transmitters. These shortwaves can propagate by reflecting off the ionosphere. The ionosphere reflects shortwaves back to the ground, enabling communication over hundreds to thousands of kilometers. However, this consumes kw-level energy. So it's only used for distance positioning. A signal is transmitted every four hundred kilometers of flight."
"Signals are emitted at 1,100 km, 1,500 km, 1,900 km, and 2,300 km to determine flight distance and safety. After 2,300 km, no more signals are sent. Currently, only two shortwave signals have been received from the Globalized Type 3 drone flying in a circumnavigation pattern to the northwest. So it passed the 1,500 km mark. The third signal was not received. Therefore, we deduced the distance was between 1,500 and 1,900 kilometers."
So this Globalized Type 3 drone also had this function. Su Han was truly surprised.
Su Han inquired, "Was our Globalized Type 3 drone shot down by the aliens on this planet?"
Chu Shi stated, "There's an 80% probability it was shot down. A 20% probability it malfunctioned due to an anomalous electromagnetic zone."
Su Han mused, "The suspected main objective we found is in the southeast direction. Now the Globalized Type 3 drone flying in the northwest has lost signal. If we were following a novel, the aliens in the southeast would definitely be evading danger from the northwest."
Chu Shi reacted, "Huh? A novel? Number 0, what kind of novel would have such a plot? If that's the case, I'd really like to read it."
Su Han quickly replied, "Let's just say there are similar novels. Have the excavator equipment been brought over this time?"
Chu Shi confirmed, "It has been brought. It can be used as soon as it's assembled. It's already assembled."
"What's already assembled?" Su Han turned around and saw a small excavator already there. Standing beside it were Ye Fan, Xiao Yan, and Lin Dong. It was clear that this small excavator had been assembled by the three of them.
Lin Dong said with a sense of pride, "After we assembled the Globalized Type 3 drone, we saw that there were also excavator assembly parts and instructions inside, so we assembled it as well."
What else could Su Han do? Of course, he praised them.
"Very good, you've done very well. Start the excavator now and dig out the engine of that crashed spaceship!"
"Yes!"
Xiao Yan was the one who got into the excavator and started working.
Ye Fan and Lin Dong stood by watching.
Lin Dong exclaimed, "Xiao Yan can really drive anything. He can even drive an excavator."
Ye Fan replied, "Isn't that normal? Xiao Yan said he's mastered operating dozens of tools. He can drive planes in the sky, tanks, cars, construction machinery, excavators, trains, and bullet trains on the ground; boats, submarines, and more in the water."
To save space, the outer shell of the cockpit of this small excavator was removed. Simultaneously, metal plates were reduced wherever possible. So as Xiao Yan looked at the excavator, people behind him could see the internal parts of the excavator directly exposed.
And this small excavator was also handled with ease by Xiao Yan.
Xiao Yan first drove the excavator to the side where the spaceship was not exposed. Then, he began to clear away the debris at the bottom bit by bit.
Xiao Yan treated this pile of garbage like a tree to clear it.
When a large amount of debris was cleared from the base of the garbage mountain, and the garbage mountain was on the verge of collapsing, Xiao Yan drove the excavator to the side and gently pushed it.
Then, the dozens of meters high garbage heap, like a tree, directly collapsed to the side. Although it didn't collapse entirely, it revealed the bottom part of the spaceship wreckage that Su Han and the others needed.
At the bottom of the spaceship wreckage, there was something that looked like an engine.
"It's exposed! The spaceship's engine is exposed! Your driving skills are truly amazing!" Lin Dong said.
Su Han looked at the component that resembled the spaceship wreckage engine and said, "The main event is here, let's take the engine out."
The seven of them, including Su Han, walked over to the spaceship engine. This spaceship engine didn't seem as large as they imagined. However, there were a total of thirteen spaceship engines. But more than half of them were clearly damaged. The remaining half also had various kinds of damage.
Chu Shi inspected them and found the spaceship engine with the smallest damaged area, saying, "Let's take this one."
As they began to dismantle it, a problem immediately arose: they couldn't find the screw holes to detach the engine.
Lin Dong asked, "How do we take this apart? I can't find where to unscrew it."
Ye Fan next to him suggested, "Then let's just cut it off. Didn't we bring a laser cutter this time? Let's use that to cut it."
Xiao Yan, standing beside them, already took out the laser cutter.
This laser cutter was miniaturized.
Xiao Yan took out the cutter and asked, "Which part do you want to cut?"
Chu Shi looked at the damaged engines and said, "Cut it at this position."
Xiao Yan immediately began cutting.
The laser cutter's beam landed on the outer metal. However, the laser only left a small white mark.
"It's completely useless! Our cutter can't cut through it at all," Xiao Yan said, putting down the cutter in frustration.
