The group of robots were spinning around in front of the crashed flying saucer like headless flies, and it was not interesting to look at it anymore, Zhao Qiang and Yang Shiyun left, and the two wanted to find the launch command base again, but after searching the underground world in this underground world, they didn't find anything abnormal.

Thinking that the so-called control room had been destroyed, and there was nothing else of value to be found here, plus Zhao Qiang wanted to charge the super battery of the drilling rig, so the two secretly returned to the crack ground, although they were puzzled, but this was not the time to solve the doubts, the two could only guess secretly.

Back in Xiaowei's flying saucer, Yang Shiqi and Donna couldn't wait any longer, and before they could stand firmly, they asked, "What's the situation?" Have you spotted aliens? ”

Zhao Qiang shook his head: "There are only a group of robots experimenting with launching spacecraft, but the result we have seen is a failure." ”

Donna couldn't believe it, "What? Launching a spaceship? Wouldn't it be that alien technology still needs to be experimented with and fails? ”

Zhao Qiang said: "We can't believe it, but it's true, in addition to the surface facilities in the underground of that entrance, everything inside may represent that the alien high-tech has stopped running, and the dust on it is half a finger thick." ”

Yang Shiqi said: "Let's ignore them for now, let's talk about whether we can go back to the ground first." ”

Yang Shiyun said: "Who knows, do your best, it's a pity that you didn't find the source of the interference signal, otherwise there would be hope for leaving here." ”

Zhao Qiang is accustomed to raising his wrist to look at his watch: "It's not early, let's take the super battery back to the lake, prepare food there, and charge the super battery at the same time, and the rest of the things can only be said when we are ready to leave...... Hey. Zhao Qiang exclaimed.

Yang Shiyun said: "What's wrong? ”

Zhao Qiang handed his wrist to Yang Shiyun: "What do you think this is?" ”

Yang Shiqi leaned over curiously, "You have flowers on your arms?" ”

Yang Shiyun's face was also surprised: "Your watch? ”

Zhao Qiang said: "Easy to use? Sure enough, the time was displayed on it, and Yang Shiyun immediately found the perspective glasses to check, and the result was really open, not the gray patch that covered her vision before.

Yang Shiyun couldn't believe it: "Isn't it, the console we destroyed underground before is real?" ”

Zhao Qiang said: "How do I know, many things here are too weird, and the results are often unexpected." ”

Yang Shiqi said: "Then what are we waiting for, hurry up and prepare to leave, is it that the anti-gravity device has also been restored, and even the charging process is saved, we will return to the ground directly, I have had enough of this." ”

Zhao Qiang opened the hatch of the flying saucer, everyone left the flying saucer, and experimented outside, and sure enough, the anti-gravity device was also restored, and the interference signal in this underground world had disappeared.

Donna is also a little impatient, although the novelty here is full of amazing discoveries, but this is not a tour, there is danger at any time, and knowing that there are thick rocks all around, the depression in her heart is particularly heavy, no one wants to stay here longer, everyone is eagerly waiting for Zhao Qiang to give the order to leave.

Zhao Qiang said calmly: "You can't be in a hurry, you still have to charge the super battery." ”

Yang Shiqi asked, "Why?" The anti-gravity devices have been restored, you've successfully turned off their jamming signals, and we'll just fly out of here. ”

Zhao Qiang said: "The problem is that if we have a rock formation several kilometers thick above our heads, how do you say we can drill through it?" ”

Yang Shiyun said: "Yes, who knows if the crack when we came down is still there, even if it is, can we find it, in case the tunnel originally dug above the crack has collapsed, then how should we go up." ”

Yang Shiqi said: "Try it and then talk about it, anyway, there is no harm in trying, if it is feasible, it will save effort." ”

Zhao Qiang said: "If it is not feasible, we have lost the drilling rig again, what else do you think of, it doesn't hurt to be safe." ”

Zhao Qiang spoke Yang Shiqi only listened, so the matter was settled, and the four of them rushed back to the lake to prepare food first, because the anti-gravity device was restored, and the running shoes naturally began to work, and the return to the lake was shortened from the original four hours to less than half an hour, which made Donna very surprised, she said: "God, are they aliens, or are you aliens!" Your technology is also very advanced. ”

Yang Shiqi was a little proud, "There are many things you don't know, I told you that the first request must be kept secret, otherwise I will kill you now." ”

Donna was not afraid of Yang Shiqi at all, and said, "Then I'll dig out slowly." ”

Zhao Qiang personally went to the lake to fish, this time he even saved the harpoon, directly used the deformed device on his wrist, found that there was a fish shot out of his wrist, caught the fish directly through the water, and then threw it on the shore of the lake, where the three girls cut the belly of the fish to clean the internal organs, and then wrapped the fish with large leaves and prepared to take it back to the cave to roast.

About an hour later, Zhao Qiang had already caught a bunch of fish like a small mountain, brought them back to the cave several times, and then the four of them started to barbecue together, although there was still no salt, but thinking that this might be the last time to eat grilled fish, everyone's interest was still very high, Yang Shiqi promised Donna in pieces, back to the ground to Yanjing, she invited her to eat, it was definitely a taste of the delicacies of the mountains and seas.

Zhao Qiang was eating grilled fish while charging the super battery, and Yang Shiyun went outside from time to time to scan around with see-through glasses, and at the critical moment of this last step, both of them were worried about accidents, especially those unknown aliens, what happened to them, they were obviously guarding high-tech civilization but they were very unbearable, but it was a contradiction to say that they were unbearable and had ultra-advanced robots.

There are more and more fish bones piled up in the hole, grilled fish and barbecue are not a grade of energy, and it is more troublesome to eat, it is not harmful to chew casually like barbecue, if you are not careful, you may be pricked by the fish, but Zhao Qiang is not bold enough to take the initiative to fight a beast, although the meat is fat and thick, but it will be troublesome if it is discovered by aliens.

Finally, after a day and a half, the super battery was fully charged, and it took more than half a day for Zhao Qiang to replenish the energy for his body, and after a big sleep, he got up with a sore tooth, Yang Shiyun's three daughters had been waiting for the flowers thanks, Donna wanted to wake up Zhao Qiang several times to go early, but was stopped by Yang Shiyun, if Zhao Qiang did not rest well, there might be problems on the way.

"You're awake." Yang Shiqi and Donna said to Zhao Qiang at the same time.

Zhao Qiang waved his hand: "Let's go, let's go back to the flying saucer and see if we can start the drilling rig." ”

Yang Shiyun and Yang Shiqi pulled Donna left and right, the four of them blew towards the crashed UFO like a gust of wind, Zhao Qiang also carried a large bag of grilled fish on his back, which was kept for food on the road, of course, the drilling time on the ground will not be too long, but in case of an accident on the way, Zhao Qiang needs to replenish energy, so it is necessary to prepare these foods.

The successfully transformed drilling rig in the weightless space is still quietly suspended in the air, and Zhao Qiang carried it out of the flying saucer by himself, and the transformed drilling rig is like a large corn cob, with the big head facing forward and the small head facing backward.

Zhao Qiang installed the super battery into the drilling rig, started the experiment, and succeeded once. Calculated with the precision of the super biochip in Zhao Qiang's brain, it would be unreasonable if it didn't succeed.

Zhao Qiang opened the hatch: "Come on, it's time for us to go." ”

Yang Shiqi asked, "What about those aliens?" ”

Zhao Qiang said: "I want to know all of them, but it is obvious that this is impossible, and there will be danger, my idea is to leave here first." ”

Yang Shiyun said: "Yes, especially with the two of you, what if something happens to you?" ”

Yang Shiqi said unhappily: "Second sister, are you saying that we are a burden?" ”

Donna pulled Yang Shiqi and said, "Shiqi, your sister is also for our good, we really can't help." ”

Yang Shiqi said: "Okay, you can also help them." ”

Donna said: "I'm helping people, not helping people." ”

Yang Shiqi said: "Since you all said so, then I will obey the majority." ”

Yang Shiyun sat in the passenger seat, and she said to Zhao Qiang: "We can use the detection system of this drilling rig to check the situation here, at least we can know how big this underground cavity is, and how many metal bodies are in it, maybe we will have a general understanding of the aliens here." ”

Zhao Qiang said: "Yes, I also have this intention, let's go!" ”

Zhao Qiang is driving this thing for the first time, but as a modifier, if you can change it to an electric drive, you must understand its structure, and can you still drive it after understanding its structure? The drilling rig sent out a burst of vibration and plunged diagonally into the formation, and the rubble kept coming up to cover up the hole just drilled, and if you didn't have the intention to look for it, you wouldn't be able to see the abnormality.

The drilling rig is sealed as a whole, and the only way to see the outside is through the monitoring system, but the monitoring system can only see the stone wall, and if you want to look further, you can only turn on the remote detection system of the drilling rig, which is the preparation work before the drilling rig, and the unknown terrain drilling ahead may be dangerous, so this detection equipment is necessary for the drilling rig, and it is best to use it to observe the geological structure of this underground world.

After walking for less than an hour, he drilled to the stone wall where Zhao Qiang and Donna had been walking before, and at this time, the drilling rig issued a red warning sound, and Yang Shiyun said: "Isn't it a rock in front?" "Because as long as it is a rock layer produced on the earth, this drill rig can drill through, but now the drill rig is on the screen and indicates that there is a material layer ahead that cannot be drilled.

Zhao Qiang thought of the appearance of the stone wall he saw before, which was indeed different from the rocks on the earth, and he said: "It may be a fallen meteorite, let's change the place." "The rig is going in a different direction, and because it's fast, you don't have to worry about the trip.

Zhao Qiang drove the drilling rig to drill underground, and as a result, the stone wall that could be drilled up could not be drilled through, which made Zhao Qiang and Yang Shiyun very annoyed, if they couldn't find the way up, they would really be trapped here, you must know that the drilling rig can not fly, it can only drill in the stone layer, relying on the power generated when the drill bit rotates to drive the whole forward.

Finally found a rock that could be drilled upward, which made Zhao Qiang and Yang Shiyun finally breathe a sigh of relief, and along the way while scanning while making the geological structure here, as the higher the upward drilling, the terrain here can be looked down, and a relatively complete geological structure map appeared in front of the two of them.
