The Wood God accelerated at full strength, and the speed of the ship climbed straight to 800 kilometers per second, and the speed was still increasing, and this acceleration alone, if the power of the engine was not considered, was enough to consume all the fuel of a conventionally fueled spaceship.

Mu Ling was still chasing the Wood God, but the distance between the two sides was no longer close, but gradually pulling away from each other, and finally escaped, Jin Ye was glad in his heart that the power system of the Wood God spaceship had improved a lot with his own participation, and it was no longer the most basic nuclear fusion engine, which gave him a chance to get rid of Mu Ling.

Wood Spirit is in the original world, and it is still of great help to Xiao Yu who has just entered the universe, first of all, when facing an unknown enemy, you can release Mu Ling to harm the opponent at a critical moment, which is a good hole card. Secondly, the radiation emitted by the wood spirit can have a strengthening effect on metal materials, and the sailing speed and the size of the spaceship in the early civilization are related to the bearing capacity of the spaceship shell material.

According to the information obtained by Jin Ye, the civilization that can master the power of nuclear fusion and carry out interstellar voyages belongs to the third-level civilization; those who can unify all the strong and weak interaction forces, master the theory of great unification, and realize the superluminal curvature navigation belong to the fourth-level civilization; those who can master, discover, and use particles beyond the speed of light, and use tachyns to detect the existence of faster-than-light flight, belong to the fifth-level civilization; as for the sixth-level civilization, they can divide space and use the fragmented space to create a small universe。

Although Jin Ye and Xiao Yu had only mastered the controlled nuclear fusion technology not long ago and had just been promoted to a third-level civilization, the strength of the new Edelman-like alloy provided by Jin Ye had already caught up with the spaceship shell that a sixth-level civilization could make.

However, Jin Ye still showed enough interest in the wood spirit, which is a creation similar to the soul, and Jin Ye's deity is the Emperor of the Underworld in the Heaven Covering World, controlling the reincarnation of all living beings in the entire world. So what kind of state of existence is the wood spirit? how does it transform from the soul? can it regain its original memory? can it be reincarnated?

These are all things that Jin Ye wants to know, fortunately, in this operation, Jin Ye has already captured enough wood spirits as samples for his experiments, and the rest of the answers can only be found by Jin Ye himself.

Loaded with the fruits of the harvest, Jin Ye returned to Titan again.

In the nearly three months that Jin Ye left, Titan was quiet as usual under Xiao Yu's control, and no accidents occurred, not even the expected invasion of black worms, causing Xiao Yu and himself to lose one or two sub-bases, this most likely scenario did not happen.

Jin Ye couldn't help but sigh at Xiao Yu's good luck, worthy of being the protagonist of this world.

In the main base, hundreds of Saturn planes take off and land back and forth every day, sending a steady stream of material resources from all over the place.

Immediately after the plane landed, there will be robots to classify the raw materials they brought, send them to different processing workshops, purify, or quench again, and then be manufactured into parts, and then there are robots to transport them to the assembly workshop, assemble them into large parts, and then transport them to a large plant to assemble them.

Countless robots are like industrious worker ants, and under the busyness of these industrious worker ants, in the factory, the village-level spaceships are gradually showing clues.

I couldn't wait to return to the main base, met Xiao Yu who was integrated into the computer again, and shared the data I had collected over the past period of time with Xiao Yu.

The relationship between Jin Ye and Xiao Yu at this time is a little special, the earth is destroyed, without considering Xiao Yu's mysterious female friend, there are only two of them left who are still alive, out of the emotion of the earth's civilization, and the relationship with the same people, the two are natural allies and have the same goal, Jin Ye has no need to hide from Xiao Yu in terms of data.

Jin Ye's data immediately attracted Xiao Yu's attention, in the era of the earth, people have never felt that there are so many lives in the universe, but since Xiao Yu and Jin Ye sailed to the present, it has not been a few years, and they have already encountered the black worm on Titan, and at this time, they have found the wood spirit, which can't help but make Xiao Yu have questions.

Is the universe really that empty?

Are there many advanced civilizations in the universe?

Is it true that the Earth was destroyed by itself, or is there some advanced civilization behind it?

"Looks like my Jupiter mining plan has to be canceled. After a long time, Xiao Yu's three-D projection shook his head and said.

"Jupiter's mining plan?" Jin Ye asked.

"I have an ambitious goal. Now, with a new type of Edelman-like alloy and an endless supply of resources, and with all our own stocks of titanium and zirconium, I plan to build a batch of "township" class spaceships, and if the power allows, I also plan to build a county-level spacecraft as a flagship. Xiao Yu introduced to Jin Ye with a little excitement that in the Earth Era, how could Xiao Yu have so many resources, and when had there been a robot with such strong execution.

But at this time, Xiao Yu can mobilize so many resources with a single hand, which is something that he never dared to think of before.

"Originally, I planned to wait for you to come back, and immediately send a mining spaceship to Jupiter to collect minerals, but unfortunately, now Jupiter is occupied by wood spirits, and now I can only go to the original location of the earth to collect resources. Xiao Yu shook his head and said, Obviously, going back to Earth to mine will consume more time, but considering the danger of Jupiter having wood spirits, at present, there is only that.

After the explosion of the earth, after several years of development, an asteroid belt around the sun has been formed in the original earth's orbit, with a total circumference of more than one billion kilometers, a width of about 10,000 kilometers, and a thickness of only about 10 kilometers. Jin Ye knew that this was formed under the action of the sun's gravity. The current earth is the "ring" of the sun, just like the rings of Saturn and Jupiter. In the future, these things can no longer be called the earth, but should be called "solar rings".

After observing the operation of the current earth through the Hope, Jin Ye sighed secretly, but he didn't know what he was sighing about, whether it was the fate of the earth, or the countless lives destroyed on it, as well as the civilization of the earth.

After determining the target, on the same day, among the main base of Titan and the ten Titan sub-bases built by Xiao Yu, more than 200 village-level mining spaceships spewed bright blue flames at the same time, slowly rising into the air and flying towards the boundless universe, flying to the original location of the earth.
