Ye Han shook his head and knocked his finger on the table a few times: "It's not a sneak attack, but a rainy day." ”

"Wait, I'm a little dizzy!" Fang Yan made a pause gesture and sorted out the thoughts in his heart, "Director Ye, I don't quite understand, which play are you playing?" ”

He is engaged in technology, and he is relatively slow to things like human feelings, and he vaguely feels that Ye Han and Luo Qi are talking about something amazing.

Ye Han didn't answer the rhetorical question, smiled slightly and said, "Fang Gong, let me ask you if something is done?" ”

"Yes, of course." Fang Yan nodded immediately.

Ye Han looked serious: "What did the aliens do along the way?" ”

"I didn't do anything, I just followed." Dialects are said as a matter of course.

Ye Han looked at Luo Qi again: "What do you think?" ”

Luo Qi smiled: "The vigilance is very strong, and the arrangements along the way are also very strict, staring at us from beginning to end, if you want to slip away, you will definitely not be able to escape their eyes, that's all for the time being." ”

Ye Han turned his gaze to Fang Yan again: "Fang Gong, what do you think?" ”

"How can I feel?" The dialect is called an inexplicable, "Is it normal for aliens to guard against us?" I can't dig out my heart and lungs if I leave me. ”

Ye Han and Luo Qi laughed together, and Ye Han said after laughing: "Fang Gong, don't you all understand, the aliens are guarding against us, we must also guard against them, it's best not to fight, in case of fighting...... Hehe, you get the idea. ”

Fang Yan nodded thoughtfully: "I think I understand what you mean...... I don't understand military matters, what I want to say is that the situation of planetary engines is very complicated, although we are just looking at the situation, but I dare to guarantee that the technology applied to planetary engines is at least a few hundred years more advanced than ours, not to mention the technology in it, even if it is surveyed and mapped, it is a very huge project. ”

Speaking of this, the excited dialect changed his tone: "We can't spend more than ten days going back and forth every time, from the perspective of convenient research, we must build a research base in the center of the earth, I will take the lead in stationing, and I won't be able to get up if I don't get a result from research!" ”

Ye Han smiled dumbly: "Fang Gong, don't get excited, I'll help you report this matter, but I can't guarantee whether the above approves it or not, you'd better write a formal report, and the possibility of approval from above is higher." ”

"Okay, I'll go back and write it right away!" When the tongue is spoken, stand up.

Ye Han hurriedly stopped: "Don't be busy first, Fang Gong, the ugly words are ahead, even if it is approved by the above, it is not certain that the aliens will not agree." ”

Fang Yan suddenly had a constipated expression on his face: "This can't do this, that can't work, how else can I study planetary engines?" ”

Ye Han thought for a while and said, "In this way, if the aliens don't agree to us also give a discount, don't build a base, and build an elevator that leads to the center of the earth, what do you say?" ”

"Elevator?" The dialect hesitated a little, "Can it work?" ”

"If it doesn't work, try it first, and then use a helicopter, now the initiative is in the hands of aliens, they say no, let's find a way." Ye Han said.

"This ......," Fang Yan hesitated, "what if the plane won't let me?" ”

"Then change the engineering vehicle, or build a slide rail, in short, the living can't let the urine suffocate to death." Ye Han said firmly.

He is now the chief steward of the forward base, and may still be the head of all the stationed personnel in the future, and must solve the worries of the researchers.

"Okay, I see." Fang Yan sighed, "If there's anything you need me to do, just say it." ”

"Don't worry, I'm definitely not polite to you." Ye Han said with a smile.

"Then you go on, I'll go back first." The tongues spoke, and turned away.

Luo Qi looked at Fang Yan's back and asked in a low voice, "Boss, is it really that difficult?" ”

Ye Han said in a low voice: "Maybe this time is too smooth, I always feel that something is not right in my heart, or maybe I am too sensitive." Okay, let's continue with what happened just now, you said that the helicopter can go down? ”

Luo Qi nodded: "There is still some hope for the helicopter." ”

Ye Han shook his head: "The helicopter is definitely not good, the diameter is only ten meters, and the rotors are too close to the wall." ”

The environment of the passage is not suitable for helicopters at all, and if you don't pay attention to the rotors, you will hit the wall and fall into the end of a plane crash.

It is not impossible to fly, but the pilot must always be nervous.

And from the ground to the center of the earth, the vertical distance is more than 4,000 kilometers, and the inclination angle of 60 degrees is oblique, and the actual distance is not too much worse than 5,000 kilometers.

Moreover, the downward airflow generated by the rotor of the helicopter is extremely strong, and one aircraft has a limited capacity, and the two aircraft must be separated from each other, otherwise the helicopter below will inevitably be seriously affected by the airflow, and it will be out of control or wrecked.

Luo Qi's face turned red, and he touched the back of his head in embarrassment: "Boss......"

"Okay, no need to explain, pay attention next time." Ye Han said.

Luo Qi hurriedly found a step for himself: "Helicopters can't do it, so you can only use a single aircraft." ”

"Not necessarily." Ye Han said, "Have you written down the terrain on the road?" ”

"Wrote it down." Luo Qi nodded immediately.

Ye Han showed a pleased smile: "That's fine, when the time comes, blast the entrance open and just smash a few cruise missiles into the hole!" ”

Although Ye Han didn't know about planetary engines, judging by common sense, that thing must be very sophisticated, as long as it was hit by a nuclear bomb, it would definitely lie down, and at that time, Europa could only be fixed at a distance of 60 million kilometers from the earth, and could no longer move.

Remove Europa's henchman, and the alien fleet will be much easier to deal with.

Luo Qi thought for a while and said, "Boss, I always think that passage should go straight to the center of the earth, are those dungeons in the middle deliberately detoured by aliens?" ”

"Feelings?" Ye Han frowned, but did not refute Luo Qi's meaning, "Why do you think so?" ”

It feels like this kind of thing is too idealistic, and he should have ignored it, but after so many years on the battlefield, it is not uncommon for veterans to escape because of their feelings.

However, Ye Han believes that the feeling of a veteran is not the sixth sense of the mystery and mystery, but the rich combat experience that plays a role.

Luo Qi thought for a while and said, "Before the passage ends, the aliens will take us into the dungeon, I think something is wrong, maybe there is something I don't want us to see." ”

Ye Han nodded slightly: "Don't mention this matter from now on, I'll apply for a batch of microrobots when I go back, and next time you follow, find a chance to release the robots and see what the aliens are doing...... How many are there that are not right? ”

"All three, I've recorded them all." Luo Qi said.

"That's good." Ye Han stood up suddenly, "Send me the video immediately!" ”

"Yes!"
