Accompanied by a sharp whistling sound, the high-explosive bomb dragged an orange-red tail flame and slammed into the rattan wall in front of the mine car.
The flame exploded instantly and spread rapidly along the dry vines.
After only burning for a short while, the vines seemed to come alive instantly and began to tremble.
The hard friction sounds were pieced together into vague syllables, forming a rich sentence that expressed the dungeon master's fucked-up mood——
"Lu Bing——I fucked your uncle——"
As soon as Long Long's words fell to the ground, the entangled rattan branches separated, making way for mining trucks to pass.
"I honked my horn politely before, but you ignored me..."
Lu Bing cooed under his breath, stepped on the accelerator, and drove the mining truck towards the exit!
Not long after leaving the vine wall exit, the sudden drop in temperature caused a layer of frost to form on the truck's windshield.
Fortunately, the mining truck has also been modified. After closing the surrounding windows, the temperature in the cab can be barely maintained.
Although it was also very cold, it was much better than when Lu Bing drove a convertible and directly felt the embrace of nature.
"Huh..." Looking at the white air exhaled in front of him, Xu Xiaoxiao glanced at the land-based mecha behind him with some worry:
"I forgot to consider the sudden drop in temperature just now... Old man and the others will not lose temperature if they stay in the mecha, right?"
"No..." Lu Bing replied feebly, "The driving principle of the Luxing Mecha is essentially close to steam drive. As long as the fission reactor keeps spinning, the two of them will not lose temperature..."
Probably feeling Xu Xiaoxiao's worry, the on-board communication of the mining truck also rang at this moment. When he picked it up, he found that it was the communication coming from the Luxing mecha.
The old man's voice came out, revealing the unique calmness of bionic androids.
"I have just debugged it. Most of the performance of the mecha 'Fortress' is fine. It's just that some of the transmission components are a little inflexible. It's probably because of the test machine and it hasn't been run in properly."
"The temperature in the dual cockpit is constant. The temperature I feel here is about 22C. The temperature in the co-cockpit may be higher, close to 28C..."
Before Hamilton could finish speaking, a burst of noisy white noise interrupted his narration, and a voice full of nonsense came from 173.
"Fat man, everything is fine here. How are you and Kegong doing?"
Xu Xiaoxiao glanced at Lu Bing and smiled maliciously: "Don't worry, Ketong and I are getting along well. He will drive the mine cart now."
"Okay...then call me if you need anything. I still need to be familiar with the operation interface of this turret. I haven't touched it in a few years, and I have almost forgotten it...His, what is this red button covered with a transparent plastic cover... …”
Lu Bing and Xu Xiaoxiao's hearts pounded hard when they heard that the World Breaker seemed to be about to press the self-destruct switch.
Fortunately, Hamilton's voice sounded in time, and they were able to dispel their worries.
"Don't worry, I have restricted the operating functions of the co-cockpit. Even if the World Breaker presses the self-destruct button, it will not be able to start the loading program."
"Huh... that's good." Xu Xiaoxiao and Lu Bing breathed a sigh of relief at the same time.
The vehicle rumbled forward, and soon left the underground and was once again riding on a wasteland.
Compared to the rugged roads of ZJ Underground City and Fengxian Shelter, the area around Kyoto Underground City seems much more empty.
There are great plains everywhere, with basically no ups and downs.
It is precisely because of this that the huge mining truck can move smoothly on the land filled with scarlet light. At first, Xu Xiaoxiao and Lu Bing were still on high alert.
After all, it's night now, and it's not only cold outside, but there are also various threats.
But after holding on for about three or four hours, the two of them got tired.
I don’t know if it’s because humans haven’t been active late at night for too long and are not aware of changes in the outside world;
Or maybe they came out at a good time and didn't run into danger by chance.
In short, no dangerous situation occurred.
Because he was bored, Xu Xiaoxiao simply turned on the in-car communication and started chatting with Hamilton.
As for the chat partner, why didn’t you choose Lu Bing or World Breaker 173?
nonsense.
One regarded her as a fool, while the other was treated as a fool by her.
Xu Xiaoxiao had no other choice except Hamilton, the bionic man.
A beep came from the car communicator, proving that the connection had been connected.
Xu Xiaoxiao chose to open the topic with a normal question: "Hamilton, how is the situation at the rear?"
The other end of the communication was silent for a while, and then came a response:
"There are no clouds in the sky and the field of vision is clear. Everything is normal here. How about you? Did you get into any trouble?"
Xu Xiaoxiao rolled his eyes at Lu Bing, the expression on his face was like a group of children in the kindergarten who were proud to have found a new partner.
She coughed lightly and responded in a slightly more enthusiastic tone than usual:
"There's no problem on my side. Lu Bing is driving now, and it's not my shift change time yet."
Hamilton said calmly:
"Then you can choose to take a rest. Our journey will last at least seventy-two hours. It is important to keep a clear mind and sufficient physical strength."
"Hehe..." Xu Xiaoxiao chuckled and tentatively said:
"Are you not sleepy now? Why don't you chat for a while? I feel quite bored..."
After saying that, Xu Xiaoxiao stared at the in-car communication expectantly, expecting Hamilton's crisp response to come from it.
However, to the woman's disappointment, Hamilton's line seemed to be disconnected, and there was no reply for a long time.
If the communication light hadn't been on, she would have even suspected that the signal was interrupted.
Just when the woman thought that Hamilton didn't want to say anything to her, a question from the bionic man came from the other end of the communication machine:
"What do you want to talk about?"
The expression on Xu Xiaoxiao's face quickly changed, and he said with a smile:
"Anything is fine... By the way, how long can the fission reactor of 'Fortress' support the mecha's activities?"
This question also came to Xu Xiaoxiao's mind temporarily. She was not familiar with mechas.
"I want it to be enough to last until we complete the mission or die."
"Although the working principle of 'Fortress' is very primitive, it has fuel rods large enough to support the mecha's activities for a long time."
"On the contrary, since the energy core of the land combat mecha after the iteration has been changed from a fission reactor to a fusion battery, the endurance is much worse..."
"Oh..." Xu Xiaoxiao nodded in understanding, and asked a little strangely: "Then why not continue to use fission reactors?"
"Because the instantaneous energy ratio is too low, the ultimate application of fission reactors can only be the 'Fortress' model."
Xu Xiaoxiao smiled sheepishly and said: "What, old man, you are talking in human language, I don't understand..."
Hamilton on the other end of the communication line sighed softly and explained:
"The speed is just too slow." "The application of fission reactors is nothing more than heating the working medium, causing it to vaporize and expand, in order to achieve the final effect of converting thermal energy into mechanical energy."
“No matter how sophisticated the parts are designed or how refined the construction process is, the essence cannot be changed.”
"The output power of the mecha is limited, which means that its speed will never increase."
"This is why fission reactors will eventually be phased out."
"I see..." Xu Xiaoxiao murmured, finally understanding the reason.
But she soon had new doubts, and there was even a little excitement in her tone.
"Old man, since you know the principles so well, can you think of a way to replicate the technology?"
"What I mean is that if we can iterate the land-based mecha three more times, develop the 'Slaughter Titan' you call it, and mass-produce it, then will the human race..."
"impossible."
Before Xu Xiaoxiao could finish his words, Lu Bing, who was driving, poured cold water on him mercilessly.
"As a protective bionic man, the old man knows a lot, but most of it only stays on the surface."
"Just like you."
"Like me?" A question mark appeared on Xu Xiaoxiao's head, "I'm not a bionic person..."
With a snap, Lu Bing held his forehead with one hand, his face full of helplessness:
"Give me an example."
"If you were thrown into the Stone Age now, could you use the knowledge in your mind to recreate this mining truck?"
Xu Xiaoxiao did not hesitate and shook his head decisively: "At most, I will teach them how to hunt and farm..."
Lu Bing shrugged: "Isn't that great? The relationship between theory and practice is not just a simple step."
"Even if you knew all the principles of this mining truck, you still couldn't produce a tire in a primitive era."
"Okay..." Xu Xiaoxiao was like a deflated rubber ball, leaning softly on the back of the chair.
"Sure enough, it was not unreasonable for the T organization to kill those top scientists in the world. Every step was calculated..."
The thing called hope is as precious as dewdrops in the sun, but the human race on this timeline has not seen that shine for a long time.
The atmosphere was gloomy and no one took up this heavy topic.
In the end, it was only when Xu Xiaoxiao, a very nervous woman, broke free from her depression that the suspended topic could continue.
"By the way, I've been wanting to ask this before..."
"Hamilton, why are you following Lu Bing?"
"What benefits has he given you that are worth your direct betrayal of Li Zhihao?"
Although Xu Xiaoxiao was not familiar with Hamilton, she still knew the character of the bionic man.
Affected by his innate mechanical thinking, Hamilton would rarely break his promise.
To put it bluntly, he is a super honest and honest person.
After the old man lost his escort target, Li Zhihao once showed kindness to him.
That's why Hamilton is willing to guard the gate of Fengxian Sanctuary.
But now, this super honest man not only betrayed Li Zhihao, but also helped Lu Bing destroy his hometown.
There must be something fishy in it!
After Hamilton heard Xu Xiaoxiao's inquiry, he did not answer directly. Instead, he asked Lu Bing:
"Can I say it?"
After getting Lu Bing's consent, he slowly said a few words:
"Because of my protection target..."
