Tang Yue sat cross-legged on the floor of the experimental cabin, holding cans in his hands, and his body was jolting with the car, like a migrant worker eating a boxed lunch on a train.

Canned beef is canned, beef is the best Qinchuan cattle beef, specially cultivated by Northwest A&F University for the Mars landing program, special food, the outside world can not buy, the meat is delicious, fatty, juicy and nutritious, compared with compressed biscuits and tomatoes, this is simply a fairy-like enjoyment, if it was put two months ago, for such a canned Tang Yue can sell the old cat.

Wait a minute.

It's a bit of a loss to exchange an old cat for a can.

Let's change to two.

Tang Yue took off the heavy Mingguang armor, every day he only had a little time to eat to get rid of this layer of impermeable turtle shell, the Mingguang armor was covered with a fine grid woven by liquid-cooled hoses, and the coolant flowed in the hose to dissipate heat, if this layer of net was straightened and connected, the total length could be more than twenty kilometers, in most cases, the inside of the Mingguang armor was not hot, but it was not hot, it was still the same stuffy.

The oxygen produced by the emergency oxygen production system always carries a smell of burnt plastic, I don't know where it comes from, and lithium hydroxide can't absorb it, this smell gathers in the Mingguang armor, and Tang Yue is about to suffocate.

Tang Yue then tore open a pack of Kobe Wagyu beef soft canned food, as we all know that Kobe Wagyu beef is the top ingredient in the restaurant, the price is expensive, you have to find an 80-year-old shop on the streets of Tokyo or Osaka, with the sake recommended by the owner, fry so two slices in a small way, five or six medium rare, you can't eat more, you will get tired of eating too much.

I don't know which god of food also made Wagyu beef canned, a package is only the size of a palm, I think it is used as an embellishment for the main meal, but Tang Yue has no consciousness of treating high-end ingredients at all, tearing open the package and pouring it into his mouth.

After eating, Tang Yue licked his fingers, licked and licked and suddenly remembered that he had just cleaned the urine collector of Mingguang Armor, and suddenly froze, half of his ring finger was still in his mouth.

Tang Yue thought for a few seconds.

Half a finger remaining.

To lick, or not to lick?

This is a problem.

Tang Yue drank a large glass of orange juice and burped contentedly.

At this time, the Martian stray dog shook and stopped, Tang Yue glanced out through the porthole, and held down the earphones, "Old cat? How did you park the car? The wheels are stuck in a pit again? ”

"Nope." The old cat replied, "Come down and take a look." ”

Tang Yue put on the Mingguang armor, put the garbage into a plastic bag, then opened the hatch and threw all the garbage out.

The old cat had already gotten out of the car and was standing on the edge of the front of the car, with his back to him, the wheels of the Martian stray dog had not sunk into the pit, everything was normal, Tang Yue stepped forward, "What's wrong?" Why park? ”

The old cat raised his paw and pointed to the horizon ahead, "That's our target." ”

Then it turned around and pointed in the direction the rover had come from, "That's Kunlun Station." ”

Tang Yue nodded.

"What do you want to say?"

The old cat didn't speak, and drew a line on the side of the wheel with his paws, "We are now one hundred and forty kilometers away from the destination, one hundred and forty kilometers away from Kunlun Station. ”

Tang Yue was startled for a moment, and immediately understood what this line meant.

This is Deadline.

Dead line.

This is the deadline that Tang Yue can reverse, this line is 140 kilometers away from the target location, 140 kilometers away from Kunlun Station, it is the middle point of the line between the departure point and the destination.

"So soon?"

"It shows that our attempts have paid off, and we have traveled a total of 40 kilometres today." The old cat snorted at the rover, and they hung solar panels on the body of the Martian stray dog, while slowing down the speed of travel considerably, charging as they went to extend the daily travel distance.

It turns out that the calculations of Lao Mao and Tang Yue are accurate, and the charging and discharging speed of the Martian stray dog battery has reached a delicate balance, and the power consumption rate of the battery has been significantly reduced.

Tang Yue...... It's too late to regret it now. The old cat turned around, "Turn around here and go back, our remaining supplies and supplies can still last until we reach Kunlun Station, once we cross this line, there will be no turning back." ”

This is the midpoint, the midpoint of the total journey, and the midpoint of material consumption, as long as Tang Yue says now that I regret not wanting to go, then the old cat will immediately drive the Martian stray dog and turn back, and they will return to Kunlun Station together to eat and drink, no longer care about any envelopes, no matter what coordinates, let them all go to hell.

Tang Yue stood beside the old cat and looked at the shallow ravine under his feet.

As long as he takes this step, then he will never be able to turn back, and the remaining materials will not be able to support him to return to Kunlun Station, and he can only go one way to the dark.

"Tang Yue, go back and forget the hellish letter." The old cat whispered, "If you don't go, no one will blame you, you don't have to be responsible for anyone, don't wait for Godot, Godot can't wait." ”

Tang Yue didn't speak.

"We still have enough survival supplies, enough food, enough fresh water, enough electricity, you can live a very moist and comfortable life when you go back, and the plants in Kunlun Station are still waiting for you to take care of ......"

Tang Yue clenched his fists and took a deep breath slowly.

"There is no hope for this road to go on, you can only wait silently in the wasteland to die, you will suffocate to death in pain because of the depletion of oxygen, do you understand?" The old cat seemed to be shaking when it saw Tang Yue, it took a step forward and grabbed Tang Yue's hand, "I don't want to see you in so much pain, and I don't want to transport your body back." ”

"Thank you for taking care of you, old cat." Tang Yue pulled the old cat's paws away, "But I'm just a wheel." ”

The old cat was stunned.

"Wheels?"

"I'm just a wheel that rolls forward by inertia, have you ever seen a wheel like this that turns and turns back?" Tang Yue took a step forward, then another step, crossed the line, and then walked forward step by step.

"I'm as free as the wind." Tang Yue walked with his arms outstretched and shouted towards the sky, "My soul is as free as the wind. ”

The old cat looked at the back of the young man who was gradually moving away, and suddenly understood that Tang Yue may never have cared about the authenticity of the letter, nor did he care whether he could win the lawsuit or whether the earth could be fully restored, he was just walking towards his doom and death step by step, firmly and resolutely.
