Last time, it was mentioned that Yang Liu and Long Yu made a verbal tirade at the forum of primitive society. It's a pity that due to cultural differences, the posts of the two could not get various comments from the original people.

After a vigorous real estate development, all the cave tribes on the top of the mountain have been relocated to a place that is easy to defend and difficult to attack. Thick wooden stakes were sharpened and driven deep into the ground, creating a wall that enclosed the entire tribal colony into a large square.

In order to be able to build the city wall horizontally and vertically, Long Yu even taught several women some experience in engineering construction. For this reason, the status of these women in the tribe was so great that they were able to command all the men.

With the protection of the wall, the attributes of the entire tribe have changed radically, from the former nomadic tribe to the agricultural tribe.

"Liu Liu, you actually store so many hybrid rice seeds in your storage equipment. Did you anticipate this situation before the crossing? Long Yu praised in a very admiring tone.

"Little junior sister, you really think highly of me. Actually, what I envisioned was completely different from the current situation. What I envision is that the two of us have finally found a planet suitable for human habitation after a long flight in the vast universe. Then it was the two of us who farmed and hunted together. Yang Liu smiled.

"It turns out that Liu Liu, you still have such romantic ideas! Some time ago, when I was browsing the Internet, I saw a website called Zhihu. There's a post about how a spacecraft can be in a difficult situation at close to the speed of light. When the speed of the spaceship exceeds half the speed of light, the near-nothing vacuum in the universe is actually filled with all sorts of dangers, the post said. Even those atoms passing through the ship will cause a lot of damage to the ship. Unless we keep the shield on. Otherwise, it is simply impossible to accelerate the spacecraft to close to the speed of light. Long Yu recalled.

"According to the calculations of the theory of relativity, if the speed of the spacecraft reaches 99% of the speed of light. The relative effects of time will become so pronounced that the passengers inside will even fly out of the galaxy within a few decades. Yang Liu discussed with great interest. In this primitive society. There is no human being who can speak a common language with either of them. Therefore, the two of them like to use small talk to pass the leisure time after cultivation.

"Yes! Zhihu mentioned a novel or movie on the Internet, about some humans flying into the depths of the galaxy in a spaceship that is close to the speed of light. Halfway through, for some reason, I had to speed up and fly out of the galaxy, finding a place with a very high vacuum to stop and repair the spaceship. But because the empty space of the universe is so far away, they must speed up to the extreme before they can find a suitable position, so that they don't die of old age during the journey. As a result, due to various accidents, the speed of the spacecraft increased and increased, so that it approached the speed of light infinitely. At such extreme speeds, the passengers in the spaceship witnessed the demise of almost the entire universe due to the relative effect of time..."Long Yo stated in a very complex tone.

"It's a creepy story!" Yang Liu sighed. How similar this is to the situation when we live with heaven and earth after attaining the Great Way. Day by day, we watched the entire universe sink and all the suns extinguish one by one, so that even the longest-lived brown dwarfs finally burned up and turned into cold rocks. The whole universe will be a dead silence. Yang Liu sighed.

"Isn't there a black hole? We'll still be able to get some energy on the black hole, right? Long Yu asked in a very concerned tone.

"Little junior sister, in fact, black holes are not so reliable. According to Hawking's theory, black holes are not like the legendary gluttony, but slowly emit radiation. Although this radiation is imperceptibly slow, it is a huge black hole under the relentless wash of time. Eventually, it will evaporate. Yang Liu struck.

"Liuliu, I feel that this world is really terrible. Even if we attain the Great Dao, it is still difficult to guarantee the end of the funeral with this world. What do you think we are still cultivating so hard for? Long Yuqing said in frustration.

"Little junior sister, these speculations we have now are based on the knowledge we have so far. But who can guarantee that all the knowledge we have so far is correct? Even the technological level of the blue home planet still hasn't given a final answer. So we have to buy ourselves more time to understand this universe. Isn't this the rhythm of the path of enlightenment? Yang Liu smiled.

"That's true! Liuliu, what you said is so good. What we have is time to think about it. Perhaps, as many scientists have speculated, outside of our universe. There are still many parallel universes. Isn't that proof of this through our various crossings with the little girl? Long Yu said happily.

Not only that, but the space jumping technology mastered by the blue parent star also points us to a research direction. As long as we can figure out those portals, the space folds. Space jumps and other principles may really be able to travel between universes as you like. Instead of bumping around like headless flies like now. Yang Liu smiled.

"Liuliu, as soon as you say that, I understand. Now that I have the motivation to cultivate again, I even feel like I want to break through now. It was really an epiphany. The benefits are endless! Long Yu's excitement was beyond words.

At this moment, a young and beautiful woman knocked on the door of Yang Liu and Long Yu.

"Lulu, did you come to us for something?" Yang Liu asked in the indigenous language. The language talent of the cultivators is not comparable to that of ordinary people, and it only took Yang Liu and Long Yu 3 days to master the indigenous language of the primitive people.

"Report to the two holy maidens, there are nearby tribes outside who are coming to defect, and the patriarch wants to ask you two to get an idea." Lulu replied respectfully. As the daughter of the patriarch, this beautiful little Lori is likely to become the next patriarch.

As Yang Liu and Long Yu brought metal smelting technology to the tribe, the life of the entire tribe has been fundamentally changed, and even the animal skin clothing they wear has been improved accordingly. After all, the advent of metal scissors and metal needles has made the production of clothing easier and more enjoyable.

Now Lulu is wearing a soft vest and fox fur skirt, and if she dyes her head green and wears smoky makeup, she will be a little girl in the 21st century on earth. (To be continued.) )
