Regarding this, Li Rui is not worried, on the one hand, there must be a road before the car reaches the mountain, on the other hand, this is the task given to him by the system, he is convinced that one day in the future, he will definitely be able to recover these garbage like alien power stones.

It's just that Yutong didn't understand, Li Rui scavenged other things outside, and took them out to exchange them for copper coins, silver coins, and even gold leaves, but why did he put away this dull garbage stone?

Treating Yutong, Li Rui didn't want to lie, so he could only explain simply, the big guy outside, the silver-white disc flying saucer, if it wants it to fly, it must not only be repaired, but also energy, and it is this alien power stone that provides energy.

Obviously, the aliens invaded here in a flying saucer, only to find that the alien power stones that had used up their energy could not be recovered. Just like a battery that can be recharged and reused multiple times, if there is no electricity in ancient times, then this kind of battery that runs out of electricity can only be thrown into the garbage basket.

But Li Rui couldn't explain to Yutong with the example of a battery, because Yutong also didn't know what a battery was.

However, Yutong can still understand, but her new question arises, why can Li Rui know this, and can he fix that big guy? If not, then what's the use of holding these garbage stones?

Li Rui suddenly found that in the face of Yutong, it was like a little girl's 100,000 whys, and in desperation, Li Rui could only say that this was his secret.

After appeasing Yutong, Li Rui instructed the golden bear to drill around to see if he could find a collection room or something, especially those colors of stones, which are now more important to Li Rui than the alien power stone, because it is installed on the mecha, and the stone of each color has different functions, and the unique yellow one is installed in the heart of the Firebird mecha.

It turned out that through a large amount of new information in his mind just now, Li Rui had found a way to repair the Firebird mecha.

Unfortunately, the Golden Bear almost turned this ground into a hornet's nest, and found nothing else, let alone several colored stones.

Li Rui could only give up and continue the search.

He put the Golden Silk Bear in the Jade Tiger Ring, walked out of the retreat of the Undead Emperor with Yutong, and told the Undead General that he had cleaned it up.

The undead general was overjoyed, and said that in order to thank Li Rui for clearing a hiding place for the undead, these undead joined forces to give him gifts to express their gratitude.

Li Rui wondered, what gifts could ordinary undead give him?

However, Li Rui had no reason to refuse the gift, and he and Yutong followed the undead general to the small mountain village again.

The hundreds of undead who survived the bloody war before were divided into two rows to greet Li Rui, each holding one thing in their hands.

Li Rui didn't care about it, but when he saw the gift from the first undead, he was almost stunned.

This is a thin black plant that resembles wild ginseng, Li Rui can not only sense that it has a strange aura, but also a faint eerie black mist on its surface.

"What is this?" he asked, shocked.

The undead spirit said embarrassedly: "Respected human boy, I really don't have anything to give you, this soul ginseng is born from all the essence of my corpse. Thousands of years ago, as my corpse weathered, this soul ginseng also withered, but I have always preserved ......"

"Nope. Li Rui hurriedly took it, "This gift is too valuable, I can't take it for nothing, so let's do it, you don't plan to leave here, so it's useless to give you a golden ticket, if I give you a small drop of the essence of the Undead Emperor that I have refined, is it useful?"

Before this ordinary undead could answer, the undead general next to him was shocked: "No, respected human beings, a small drop of essence from the Undead Emperor is far more than this soul ginseng." ”

"Useful?" asked Li Rui, tilting his head.

The undead general bent down, "It's so useful, you should know that our undead can survive for 10,000 years, not because we can live forever, but because we can devour each other for a long time, and only by constantly devouring other undead can we get longer." ”

"You kill each other?"

"No, this ancient battlefield is not just a bunch of our undead, there are other places where we often have devouring wars. ”

Li Rui heard the enlightenment, and thought about it, this ancient battlefield under the sea is too big, it is a barren mountain and wild ridge that cannot be seen at a glance.

Li Rui thought for a moment, and said to the undead general sincerely: "The essence of the Undead Emperor is also useful to me, and I will need it when I cultivate my soul in the future, but this undead spirit has given me a soul ginseng that evolved from its corpse, and I can't say anything useful if I don't give it anything." ”

I didn't want Li Rui's words to fall, and the other undead all hurriedly handed over their gifts, hoping that Li Rui would take a look......

Li Rui could only shout: "Don't worry, come one by one, but whoever gives me a gift, I will give it a small drop of the essence of the Undead Emperor." ”

That's right, as soon as they were handed out, Li Rui quickly sensed the side, and he forced the surprise in his heart, although these gifts are different, they all have the same characteristics, that is, they reveal a strange aura, even if they are far less than the soul grass, I believe that they also have an auxiliary effect on soul cultivation.

Li Rui took the gifts one by one in ecstasy in his heart, not noticing that the tower-like undead general suddenly disappeared, and when it appeared again, the giant was actually holding something in his hand.

It's not small, but it's like a speck of dust in its giant hands.

It's a stone, an eerie black stone.

Li Rui froze, "Undead General, you won't tell you that this black stone is the evolution of your corpse, right?"

"No!" the Undead General shook his huge illusory head, "This is the collection of the Undead Emperor, a spar that has been precipitated by this mass grave for 10,000 years, similar to a mineral crystal. ”

"I'm dropping God!" Li Rui snatched it when he heard it, and almost at the same time, he also gave the Undead General a small drop of the largest Undead Emperor Essence drop.

Yutong behind him suddenly whispered: "Brother Li, give me this black crystal." ”

"What?" Li Rui turned his head.

Yu Tong said shyly: "My soul suit hook was given to you as a love token, I have no soul suit, if you give me this black crystal, I can ask the refining master to help me refine a soul suit necklace." ”

Li Rui was really reluctant to hear this, but the soul hook that Yutong gave him had already been damaged under the mechanical arm of the Undead Emperor, and this black crystal was too valuable, and he guessed that it was only a refining material of the upper grade of the Heavenly Rank.

However, Li Rui thought about it for a while and handed it to Yutong.

But although Yutong took it, her beautiful eyes did not leave the Jade Tiger Ring on Li Rui's fingers, because she knew very well that there were just hundreds of gifts in it, and each gift given to Li Rui by the undead could either refine the soul pill or refine the soul suit.

At this time, the golden bear in the jade tiger ring muttered to convey the meaning: "Master, it's too disgusting, don't put these weird things by my side, that girl wants it, you can give it to her." ”
