Just as sailors can locate through night stars in the vast sea, during interstellar travel, pulsars can be used to navigate the vast universe.

The formation of pulsars occurs when a massive star evolves into a supernova and collapses into a neutron star. The pulsar will continue to rotate and emit electromagnetic radiation outward. The beams of these radiated light will flash at specific frequencies, just like a beacon on a lighthouse in the vast ocean.

Moreover, the pulsar spin rules are very stable, even comparable to the stability of atomic clocks in measuring time. Obviously, in interstellar travel, pulsars can be regarded as reliable beacons, and then the triangular positioning method can be used to accurately calculate their position.

At this moment, there was darkness outside the spacecraft, and even the stars could not be seen, without any light, and there was a void silence.

"It was detected that there was a large amount of interstellar material around it, mainly hydrogen. The spacecraft may be in a high-density interstellar dust, and dark clouds blocked all light." The data analyst said.

"Not good, boss, if my judgment is not wrong, this universe should be the original breeding ground for a star, and a new star should be born here in millions of years." Chu Siyuan said with his jaw holding.

"So?" asked another colleague.

"This means that the surrounding area is as long as light-years... If this is a nebula cluster, it may even reach a length of several light-years. In other words, we cannot get out. Only by leaving this star area and obtaining a better field of view can we discover pulsars and then calibrate. We cannot fly far with a working-free nuclear power engine, and we can only make a random jump." Chu Siyuan explained.

"What? Random Jump?" Eva Yelianna said in surprise: "Chu, you should understand how dangerous it is to make random Jump in the unknown interstellar world? We all know nothing about it here at the moment..."

"Of course I know that if we don't do this, we can't get out of this dark cloud, so we can only return the same way." Chu Siyuan said, pointing to the artificial wormhole outside the porthole. There is also a binary star resonance system at this end. The data detected is exactly the same as the periphery of the Kuiper Belt. The two systems form a stable wormhole bridge, connecting this unknown universe that is more than so far away and the solar system.

In any case, the one who creates artificial wormholes is an extremely powerful civilization. It is an existence that can only be looked up to when it reaches the current technological level of human beings. Antimatter, artificial gravity, and artificial wormholes are all things that human civilization cannot reach.

"Wentian, Wentian, it seems that we can only go and ask about the sky." Li Chuan said leisurely, then walked towards the console and asked, "How much fuel is left in the spacecraft?"

"The remaining nuclear material is 61.7%." Ai voice broadcast came.

At this time, Eva Yelianna walked up and said, "The nebula cluster is at least light-year scale, and our jump consumes nearly 40% of the energy, which is only a scale jump of 62 astronomical units. It is useless to jump within the cluster."

62 astronomical units, equivalent to 9.2 billion kilometers, or 0.09804% of a light year, Eva's meaning is very clear, and even if it is a jump, it is impossible to leave this nebula.

For a moment, the situation continued to stalemate, and the others watched silently, waiting for Li Chuan to make a decision.

After a while, Chu Siyuan suddenly had a bright light in his eyes, and he looked at Li Chuan and said, "Boss, I have a way. As long as we reduce the quality of the jump, we can do it..." As he said, Chu Siyuan quickly ran to the console, opened the display panel and quickly modeled and calculated, and added: "Under the same energy consumption, as long as the quality of the jump is reduced, the range of the jump scale can be expanded... If we remove the jump room and only carry the fusion core, the jump room and the work compartment..."

Chu Siyuan quickly calculated, and after a while the data results were listed, saying: "The total transition mass is only 72 tons, which is 91.5% less mass, and the remaining fuel can meet... the limit scale of one-time transition can reach 11.7 light years."

While speaking, Chu Siyuan withdrew his gaze and looked around everyone with a slightly excited gaze.

"Brother, do you mean to dismantle the spaceship? Here? Are you sure it's not a joke?" Liu Jin said in surprise.

"This method is feasible!" Li Chuan said, "I designed the spacecraft and built in a modular manner. It is composed of 184 relatively independent modules. The fusion core and the transition room can be unloaded independently from the spacecraft... Just do as Xiao Chu said, this is all!"

Li Chuan made a decision directly, and the crew began to unload the fusion core and the transition room as required. However, before that, the fusion core combustion chamber worked for a period of time, consumed about 2.2% of the remaining fusion nuclear material, collected fusion energy and saved it in the reversal energy core matrix to ensure that the spacecraft had surplus energy back to the solar system.

The entire operation took 87 hours to complete, and the sales volume was already good. A small jump shuttle completed modular assembly, with a total mass of exactly 72 tons, including a fusion core, a transition room, a work chamber, a spare quantum computer, communication and other modules. It takes as little as possible to reduce the overall quality of the shuttle.

After 95th hour, everything was done. Li Chuan summoned all the members on the bridge, "This operation is enough for Xiao Chu. Liu Jin, you are the acting captain. You are temporarily staying near the wormhole. We meet and need you to guide the beacon."

"I understand!" Liu Jin nodded and responded.

After explaining the matter here, Li Chuan shook his eyes at Chu Siyuan and left the bridge. The latter hurriedly followed. Six minutes later, the two entered the modified jump shuttle. Ten minutes later, the "Wentian" spacecraft started the engine and actively distanced the jump shuttle. The shuttle only had the jump capability but no relative conventional propulsion engine.

The four independent working-free nuclear-powered engines on the spacecraft can be removed and installed, but that will increase the mass of more than 80 tons and the fuel will not be enough.

The temporary tasks were also planned. The shuttle used the remaining energy to provide two jumps. The first jump was to find the pulsar and complete the calibration task. First figure out where it was here, and then use the last jump to meet with Liu Jin and others. Fortunately, there was a quantum communication beacon guide. After the jump was back, wait for Liu Jin and others to drive the spaceship to recover.

About twenty minutes later, the jump shuttle and the "Wentian" spacecraft had already opened a relative distance of more than 6,000 kilometers.

"Fortunately, there is Zhongjing material, otherwise it would be impossible. If it is a conventional alloy material, the shuttle machine will start at least 300 tons of mass." In the shuttle machine, Li Chuan debugged the machinery and equipment with a calm face. Next to them is the fusion core. The temperature in the combustion chamber reached hundreds of millions of degrees Celsius at a distance of less than one meter.

"The jump engine is ready, boss!" Chu Siyuan sat next to him and stared at various data. His hands never stopped. The work cabin was crowded, but there was nothing he could do. Li Chuan opened a display panel and looked at it. The nuclear fuel was left with 57%, only half of the first half.

"The longest distance?" Li Chuan asked.

"8.2 light years." Chu Siyuan replied. In other words, the shuttle will randomly jump in the interstellar space with a radius of about 8 light years, and within this range, it may appear in any space area.

"Just jump, just don't give me a 'one centimeter flash'." Li Chuan issued the last password, and ai's electronic synthesized voice broadcast rang: "The jump engine is about to start, the countdown is 9, 8, 7...2...1 starts!"
