"Three, two, one, launch!" Mark's hand lightly rested on the launch button, and the electrical signal was transmitted to the ion cannon through the computer system on the spaceship, and all the remaining energy in the ion cannon poured out without reservation at this moment, through the heating cannon barrel that had not been fully buffered because of the previous launch, and rushed into the space, the spacecraft was pushed in the opposite direction because of the strong recoil, and the small space bubbles around it were like the Red Sea divided by Moses, and were separated on both sides of the spaceship.

The barrel of the cannon has not been cooled in the first place, it has become very fragile, the powerful momentum of the cannon suddenly washed away the barrel, and the originally damaged spaceship was disassembled because it could not withstand such a strong propulsion, the broken fragments were scattered, and the scattered fragments were scattered all over the road of time and space, and those small mass fragments were instantly captured and assimilated by the surrounding space-time system, and the scattering became a high-dimensional crystallization with multiple cones that were constantly moving topological in space.

"Catapult!" With a shout from the other party, Mark quickly started the program, and started the ejection just when the buffer layer in front of him collapsed.

Sun Tan and Mark when the potential energy of the spaceship was at its maximum, they issued the last command on this spaceship, and the mecha they assembled was instantly ejected into the outside space-time by the catapult system, and the small space bubbles around were agitated by the potential energy and stretched into straight lines, due to the speed of movement, Sun Tan and Mark couldn't see the scenery in front of them at all, countless scenes from different space-time reference frames, tumbling in front of their eyes, as if they were being quickly turned pages. It's like layers of paper tossed by the wind.

Both of them were wrapped in heavy mechas, their bodies could not move, it felt like a large stone pressed against their chests, this uncomfortable stiffness lasted for a long time, until they broke through several layers of time and space bubbles, the speed of flight slowly slowed down, and Sun Tan and Mark were enough to look down on the scenery in front of them...... The scenery of this nascent universe unfolded in front of the eyes of the two of them, this scenery is not something that everyone can appreciate, Mark has developed the ability to look directly at the high-dimensional space because of the experience of the dream world, and Sun Tan grasps and understands it by reducing the things in front of him into a mathematical model, which is just a picture of chaotic lines in the eyes of ordinary people, and an incomparably magnificent and wonderful picture in their eyes.

In their eyes, the main body of the small spaceship carrying the fort and losing control has shrunk into a small point, Sun Tan silently recorded in his heart the moment when the spaceship disappeared to the point where it could not be seen, he will always remember this moment, the efforts made by himself and countless people who have devoted themselves to it, and the great contributions made to human civilization, hoping that these deeds can be recorded in the annals of human history forever in the future......

"If the world is full of darkness, I would like to be a star and light up the night sky...... The starry sky is so shining...... It's because of me, you, and everyone who stands in the depths of the stars......" Sun Tan silently sang an old poem, mourning the spaceship, the pulsar and the curvature gap, and the countless people who dedicated themselves to this cause, hoping that no one will sacrifice for this in the future...... Of course, this is an ethereal wish, as long as humanity still has to move forward, there will be thorns ahead, he looked at Mark beside him, and Sun Tan read the same enthusiasm in his eyes. Death is a sign of new life, and the destruction of that pulsar has brought the possibility of human civilization, and the death of the great universe has created the rebirth of this miniature universe......

The resistance in time and space is still beyond Sun Tan's prediction, they hit these micro space bubbles, those small space bubbles will not cause space movement, but they will lose the power on their bodies, and soon the inertia of the spaceship is exhausted, Sun Tan and Mark turned on the power system on the mecha itself and continued to move towards the target space bubble, the short distance seems so far away now, at this moment the power system and residual inertia of the mecha are the only straw for Sun Tan and Mark to save their lives, If kinetic energy and inertia run out, they will lose hope of survival.

Time passed second by second, and the energy of the mecha itself had all been exhausted, and only inertia was slowly pushing the two forward. There is still a short 20 centimeter standard space ruler from the space bubble, but in the eyes of the two of them, it is as difficult to be crossed as a sky slash, and the effect of inertia gradually decreases in the resistance of space...... The speed of the two of them was dropping dramatically, and ironically, by the time they slid past, the space-time bubble might have just been within reach.

"Use this." Sun Tan opened a spare oxygen tank, released the pressure inside as power, and at the same time constantly unloaded the heavy objects on the mecha and threw them in the opposite direction of the space bubble, converting the excess mass into kinetic energy, Mark also followed him to do the same action, the two of them almost kept the same speed forward, and slowed down at the same time, at this time they were less than ten meters away from the space bubble.

Sun Tan threw the completely deflated oxygen tank into the distance, and then used to remove the extra armor on his body, and the two of them moved desperately towards the shore like drowning people, until there was nothing extra on their bodies to maintain their speed, and the space bubble itself was also moving, if their speed began to fall below the speed at which it moved, then they would never be able to catch up with it......

"No, everything that can be thrown has been thrown away...... It seems that this vast gate of time and space is our burial place" Sun Tan looked at the space in front of him and said with a wry smile, he stretched out a hand, but he couldn't hold it, his protective armor had been disassembled to the limit, if he continued to unload the weight and accelerate, even if he could get by, he would freeze to death, or the air pressure was unbalanced and exploded to death.

Mark had a big smile on his face at this moment, he had thrown away all the heavy things like Sun Tan, and at this moment he heard the illusory voice again, Mark knew that he still had something to do, and he also knew what to do next.

"No, we still have a load to work with." Mark stretched out his hands and pressed Sun Tan's back, and stuffed the oxygen tank he was using to him, the power in the mecha ran out, and the communication began to blur, but it still supported the two to finish the last paragraph.

"Hey! What are you doing? Loosen! Let's go together! Sun Tan realized what Mark was going to do, but it was too late.

"My kinetic energy, to you." Mark pushed Sun Tan forward with all his might, transforming his mass into kinetic energy in his body, Sun Tan struggled to be pushed into the space bubble above, while Mark's own body quickly sank in the opposite direction.
