Since that human race was all mortals, and they also knew that the ability of the immortal cultivators was high, they only allowed the Thunder Sky Clan's team to send one person over, and if there were too many people, they would refuse to board the ship.

Whoever he sent was not very relieved, Lei Tianzi knew that the immortal cultivators under his command were used to being arrogant, and if they disagreed, they would have conflicts with others, and once someone was killed or injured, they would form hatred, so he decided to go over and see for himself, and the mortals who could gather a starry sky battleship must be a powerful force in science and technology.

Lei Tianzi changed into a cloth suit that he hadn't worn for hundreds of years, and he didn't even wear a defensive armor, so the big thorn flew over, and the Terran starry sky warship had already scanned that Lei Tianzi didn't have a magic weapon, and they seemed to be very surprised, and opened the hatch early to welcome Lei Tianzi, and played a cheerful music.

Lei Tianzi entered through the wide open hatch, and then through a decompression chamber, looking around, these two cabins were quite beautiful, and very practical, he concluded in his heart that the group of people in front of him must belong to people with more advanced science and technology, at least more advanced than the earthlings that Lei Tianzi had seen.

After the decompression chamber, a group of men and women in uniform stood at the door, and when they saw Lei Tianzi, they immediately covered their hearts with their right hands and bowed, Lei Tianzi knew that this was a meeting etiquette, and hurriedly returned the salute to each other.

The man standing at the front was probably in his forties, and he spoke, "Welcome cultivators to the Brave spaceship, I am the captain here, my name is Jin Kaiyuan. ”

"Hello, my name is Lei Tianzi. ”

Jin Kaiyuan shook hands with Lei Tianzi, but this etiquette was initiated by Lei Tianzi, Jin Kaiyuan may not have the experience of shaking hands with people, and his movements are relatively dull.

Lei Tianzi's glazed divine sense swept and found that the people here were really mortals, there was no immortal cultivator, but there were two people who cultivated to belong to the spiritual period, which showed that Jin Kaiyuan and the others were not unable to cultivate, it seemed that they had not embarked on the path of cultivation, I don't know if it was because there were no resources or other reasons.

Lei Tianzi took out thousands of jars of Tianzilang wine, and it didn't seem appropriate to send other things, and the spirit fruit was a kind of immortal treasure that mortals couldn't eat more, it was a tonic for immortal cultivators, and it was poison for mortals.

As for the magic weapon space and immortal crystals, mortals can't use them.

Jin Kaiyuan smiled bitterly and said, "When we entered the starry sky, it was the first time we encountered a cultivator who was so generous. ”

"Do they look down on you?"

"You're really right!" Jin Kaiyuan gave a thumbs up and said, "If it weren't for the fact that we don't have any money, I'm afraid we would have been robbed a long time ago." ”

Lei Tianzi couldn't help but laugh and said, "Why don't you cultivate?"

"A matter of philosophy. Jin Kaiyuan looked at Lei Tianzi very confused, and then explained: "We are from the Shui Yuan Star in the Qiluo Star Domain, where there are no immortal cultivators at all, and then after millions of years of long historical evolution, we have been able to conquer the starry sky, and sent a lot of fleets to find other human beings, but I didn't expect that most of the cultivators in the starry sky are cultivators, they look down on us, called mortals, and really regard themselves as immortals!"

Lei Tianzi nodded slightly, the current situation in the immortal cultivation world is like this, immortals are different, basically they rarely come and go, although they are all human beings, they have the same tense relationship with other races, and sometimes it is better to have a close relationship with immortal cultivators of other races.

Then Jin Kaiyuan talked about the Brave they controlled, which had walked in the black starry sky for three thousand years and changed twelve captains.

Lei Tianzi was very surprised, he always thought that mortals only had a hundred years of life, but Jin Kaiyuan said that they already had a very developed medicine, overcoming the secret of human aging, a person can live for about a thousand years, in this way, the scientific process has been greatly strengthened, talented scientists can live to about a thousand years old, and the research in a separate field is more in-depth.

Jin Kaiyuan seems to be in his forties, but he has actually lived for more than eight hundred years, which is almost the same as an immortal cultivator in the solid foundation period.

Lei Tianzi was very happy, talking about a few medical problems, Jin Kaiyuan was not a medical expert, he invited a woman to talk to Lei Tianzi about medicine, Lei Tianzi found that this elegant woman's medical theory was very exquisite, at least a lot higher than the level of the teacher Chi Deshui.

The secret of longevity researched by the Terrans of Shui Yuan Xing is a potion containing vitality, not collecting plants and animals as medicinal materials, but all based on chemical synthesis, this drug injected into the human body can slow down the aging time of the human body.

Lei Tianzi said: "Can I take some anti-aging drugs? and I am willing to cooperate with you in many fields." ”

Jin Kaiyuan thought for a while and agreed, science and technology can only be secreted in the field of top weapon systems, and most of the technology in other fields can be shared with others.

After Lei Tianzi returned to the Cave Heaven Blessed Land, he began to recruit volunteers in the age group under 20.

Hearing that it was to learn skills from mortals, most of the immortal cultivators retreated, and in the end, Lei Tianzi had to forcibly order his children to learn techniques.

There weren't too many of his children in the Cave Heaven Blessed Land, and most of them went to guard one side, but fortunately, Pang Duoer became pregnant again immediately after returning from the Origin Star Domain, and this time after ten years of gestation, she gave birth to hexaplets.

The number of children born to Pang Duoer at one time may have something to do with her background, Pang Duoer belongs to the river mussel creature, and the number of eggs laid is hundreds of millions of dollars.

Now Pang Duoer's six children are all five years old, because they were born to be infancy cultivators, and their bodies are developing rapidly, Pang Duoer named the children Lei Luoqi, Lei Luofan, Lei Luo Xiangyu, Lei Luo Xiaoxiao, Lei Luo North and South, and Lei Luo Eleven.

Anyway, her children's names all have the word "Luo" in them, which is obviously different from Lei Tianzi's other children.

But Pang Duoer really doesn't have any culture, it's just Lei Luo North and South, and others can't say anything, but Lei Luo Eleven is obviously a girl, but the name is extremely weird, and it doesn't feel like a girl's name.

It can be explained clearly from the ranking of brothers and sisters, after all, it is ranked eleven, and outsiders will definitely feel inexplicable when they hear it.

In addition to these six children, plus Lei Luojing and her son-in-law Lu Yong, Lu Qi and others, they finally managed to make a learning team of less than a thousand people, and it can be regarded as Lei Tianzi attaching too much importance to mortal skills, and gave these people twice as much treatment as the sergeants of the Lei Tian clan.

Most of them sign up for high salaries, and they are not too optimistic about the skills of mortals.

Lei Luojing didn't want to learn any technology, but fortunately, her husband Lu Yong accompanied her, so she came together, and now Lei Luojing is also twenty-six years old, originally past the age of learning, because there are too few people to learn, Lei Tianzi named Lei Luojing to participate, and she came to the Brave unhappily.

Everyone else went to learn technology, Lei Tianzi and Jin Kaiyuan chatted and drank together, and Jin Kaiyuan said: "Thunder God King, you are fortunate to have met us, if you continue to move forward, maybe the whole army will be wiped out." ”

"What's the matter?Is there an alien army in front?" Lei Tianzi never told Jin Kaiyuan about how powerful his Lei Tian clan was, and he did not expose his strong military strength in front of Jin Kaiyuan.

"It's not human power, a hundred years ago, there was a planetary explosion here, and the aftermath of the explosion affected the starry sky in a radius of trillions of kilometers, and the place we are in at this time is still on the verge of the big bang, and it will take another ten years or so, and the residual rays of the explosion will weaken, so that we can pass carefully. ”

"Oh, I see. Lei Tianzi remained silent, he didn't think so, Jin Kai couldn't get through, it didn't mean that immortal cultivators couldn't get by.

Afterwards, a team of Lei Tian warriors were sent to explore the way, there was no trace of this part of the sergeants, Lei Tianzi died at this time, and he didn't dare to continue to send people to test, Jin Kaiyuan and others were able to sail on a starry sky battleship for thousands of years, and they must have no less technology than immortal cultivators, don't underestimate the ability of mortals, Jin Kaiyuan said that there is danger, and immortal cultivators may not be able to resist that kind of danger.

Lei Tianzi and the others quietly settled down in the starry sky, and arranged two billion kilometers of long-range sentinel spies in all directions.

Later, Lei Tianzi knew that Jin Kaiyuan's technology could monitor the starry sky tens of billions of kilometers away, even in the dark, he could see clearly any movement in the starry sky, and he was more convinced of the ability of those people in Jin Kaiyuan, according to the scientific and technological development of Shui Yuan Xing, human beings in the future can use science and technology to conquer the starry sky, there is no need to cultivate anymore, in fact, the ability of immortal cultivators belongs to individuals, such as being able to fly, and fighting, etc., science and technology use the power of the group, no matter how far science and technology develop, human beings cannot do without the environment of group living, immortal cultivators are not, as long as they reach the infancy period, a person can still cross the starry sky, but when you encounter an enemy, you can only ask for more blessings.

Lei Tianzi decided to add an item to the sergeants of the Lei Tian clan, that is, to master science and technology and complete it as a military task, so that the Lei Tian clan has cultivation skills and scientific development to walk on two legs, and will be invincible in the starry sky in the future, and there will definitely be dissatisfied voices at the beginning, but fortunately, Lei Tianzi's prestige is high, which is enough to suppress all opposition voices.

Immortal cultivators have an incomparably powerful divine sense power, which is an advantage that mortals can't catch up with, and they are much stronger than mortals in terms of memory, calculation ability, and ability to observe from a distance.

Lei Luojing and the others have a very fast learning speed, and after a year, they have begun to advance from the learning stage to the discussion stage, they have the ability to compete with the teacher, Jin Kaiyuan originally didn't know much about immortal cultivators, he used to be able to see immortal cultivators flying around, and they could use spells, they didn't know much about the power of divine consciousness, and immortal cultivators didn't disdain to interact with mortals, and they were very disdainful of the tools and equipment used by mortals.

So much so that there is a huge gap between mortals and immortal cultivators, and both sides look down on each other, always thinking that what they do is the best.

Jin Kaiyuan saw that the ability of immortal cultivators was far stronger than he imagined, and his thinking also changed a little, and he no longer rested on his laurels, and put forward several conditions to Lei Tianzi, the first of which was to ask Lei Tianzi to help them cultivate a group of immortal cultivators, including all the exercises and spells and materials such as cultivation experience.

Lei Tianzi agreed, Jin Kaiyuan proposed to need a batch of magic weapons, as well as the elixir taken by the immortal cultivator and some other spiritual herbs and elixirs to assist in cultivation, for this article, Lei Tianzi had already prepared, and also proposed the corresponding exchange conditions, the immortal cultivator exchanged resources for Jin Kaiyuan's equipment, including cutting-edge weapons and other equipment.

Jin Kaiyuan didn't want to exchange equipment for cultivators' resources, in his opinion, there was no precedent for such an exchange as a reference, and his side would definitely suffer, for example, how much was a solid foundation pill?

This negotiation was very difficult, mainly because Jin Kaiyuan always felt that he had suffered too much.
