In the few days after Su Zhan's death, although the Su family was a very ordinary small family, they were also busy for several days.

A little bit of rain, stepping on the rain, Su Wu came to the uncle's house.

After explaining the reason, Su Wu handed the bank card and battle card left by Su Zhan to his uncle. Uncle is also a petty local official, so he naturally knows the purpose of the battle card.

"Since it was given to you by your brother Zhan, you can take it. The uncle looked at the bank card and battle card, and suddenly smiled, and Su Zhan naturally left a letter for them.

"Stay and have a meal. Your Brother Yun is in the study, you go to him first. After speaking, Su Wu's uncle handed Su Wu the bank card and battle card, and patted Su Wu on the shoulder.

Su Wu came to the study and saw that Su Yun was reading a book, which was a book about formations.

"Brother. Su Wu screamed softly.

Su Yun turned his head and smiled, "Sit." ”

Su Wu came to Su Yun, sat down, and looked at Su Yun with glasses, his eyes were still slightly swollen. Su Zhan is Su Yun's own brother, and he is a little sadder than Su Wu compared to Su Yun.

"Do you like formations?" asked Su Yun.

Su Wu nodded, in fact, he also has a skill in the martial arts, which is the formation. But a person like him whose system is too poor to cultivate spiritual power, even if the formation theory is extremely outstanding, cannot actually use the formation.

"Actually, the formation does not have to have spiritual power, but only needs to use spiritual power to draw the structure of the formation, so that they are connected and form many related nodes. Arrayists are like programmers, they don't need to write their own code, they need a tool. Do you understand my words?" Su Yun said softly.

Su Wu nodded obediently, what Su Yun meant was that although Su Wu couldn't use his spiritual power to depict the formation, as long as there were spirit stones or other mediums, as long as the formation map was completed.

Su Yun smiled very happily, and Su Zhan told him in the letter that he would help Su Wu become strong. And the only thing Su Yun knew was that Su Wu was a formation genius, so he was ready to teach Su Wu the formation. For Su Wu, this couldn't be more suitable.

After exchanging some formation knowledge, Su Wu was finally promoted from a primary school student to a junior high school student.

"Brother, do you know what a demon crystal is?" Su Wu was holding a high-level formation book, and suddenly saw the 'demon crystal'.

Su Yun said unhurriedly: "The demon crystal is the essence of the demon beast, the more powerful the demon beast, the stronger the demon crystal will be, and the more functions it will have." Legend has it that the Soul Demon Crystal has a magical ability to suck the soul of a dying person into it, and the dying person can live for at least ten years, and with the help of an unknown number of divine objects, it can resurrect a person. But... It's just a legend, even if it's true, what can it be?" At the end of speaking, Su Yun seemed to see the reality clearly, and there was a kind of gloom.

"The meal should be ready, let's go eat. Su Yun was afraid that his emotions had affected Su Wu, so he hurriedly smiled.

After eating, Su Wu said goodbye.

When he got home, he immediately opened the battle card shop, looking for information about the demon crystal.

Beginner Demon Crystal (Body Refining Realm):

Segments 1~12: 100~5000 contribution points

Intermediate Demon Crystal (Imperial Spirit Realm):

1~10 sections: 8000~20,000 contribution points

High-level Demon Crystal (Soul Realm):

1~5 sections: 50,000~300,000 contribution points

Best Demon Crystal (Access requires Ensign or Parallel Clearance)

Su Wu took a deep breath, from Su Zhan's letter, he knew that contribution points were not good at all. The 100,000 contribution points he obtained, one is that maybe the invention is really important, and the other is that there may be Yan Lao operating in it.

However, thinking of the materials for the black technology upgrade in his hand, Su Wu spent 120 contribution points to buy a lowest-level demon crystal, first, to see what kind of thing the demon crystal is, and secondly, to verify how powerful this black technology in his hand is. Anyway, it didn't say what level of upgrade materials you wanted.

Soon, Su Wu received the package. But it wasn't delivered by a courier, but by a plainclothes man with a mask. Su Wucai doesn't care who sends the things, as long as he can get them.

When I opened the box, I saw a knuckle-sized crystal. The whole body is transparent, and there are some impurities in it, but when Su Wu took it in his hand, he felt a trace of weight and temperature.

After smelling it, there was no smell, and Su Wu felt that his mind became refreshed.

The hardness is not as hard as imagined, just like transparent glue, Su Wu gently pinched out a little with his fingernails, and then put it in his mouth. He checked that the demon crystal was actually edible.

The taste is average, but it melts in your mouth and has an excellent texture. Soon, Su Wu had a slight feeling, but it was not too obvious.

Su Wu decided to get more and see what the effect would be. But the watch in his hand didn't seem to be happy, and suddenly stabbed with electricity, and then, the demon crystal disappeared in front of Su Wu's eyes.

"Damn!" Su Wu subconsciously shouted, although it was very low-level, it was also worth 120 contribution points!

He hurriedly raised his hand and looked at his watch. A string of characters appears in my mind: system upgrade······

Su Wu was speechless, damn it, it's really black technology. An electronic watch can be cultivated and upgraded!

Speechless is speechless, but after seeing the watch, Su Wu suddenly thought of a person, silly Bai Tian!

Because of many things, Su Wu forgot all about the stupid Bai Tian.

However, the fee paid by the hotel has not yet arrived, I don't know if the silly Bai Tian has left?

Su Wu hurriedly got dressed and took a taxi to the hotel.

Maybe it's because I'm thinking too much, silly and sweet and carefree eating food and watching TV. When he saw Su Wu coming, he was not surprised at all, and he was even abandoned······

"People will eventually die, or heavier than Mount Tai, or lighter than a feather. Your brother's sacrifice is heavier than Mount Tai. Ye Chengfeng said softly.

But when Su Wu saw his pretended profoundness, he wanted to beat him to death!

Sensing Su Wu's unkind eyes, Ye Chengfeng hurriedly stood up, losing his previous appearance.

"How do you know?" Su Wu couldn't figure it out, how did this guy know that his eldest brother had died? Wait, he said before that he knew about computers.

"I ······ I guess. Ye Chengfeng said nonsense.

Su Wu glared at him with disdain and said, "Don't peep at me again in the future! ”

"Also, why don't you go home and always eat and drink at my place?" Su Wu teased.

Ye Chengfeng was also a little embarrassed, he wanted to rob Su Wu before, but he was mistakenly wrapped up by Su Wu... Offering for a few days, yes! It's an offering! It's not a package!

Seeing Ye Chengfeng looking at him directly, Su Wu was also speechless, is this guy eyeless?

As the saying goes, cannibalistic hands are short. Aren't you ready to do something when you give money?

"I don't have a home, so you'll treat me as a bum. Ye Chengfeng puffed out his cheeks, and his shameless appearance made Su Wu laugh.

But Su Wu didn't get used to him, and said with a very angry look: "Hmph! Okay, I'll leave the room later, and then go to the police station to report the case, and say that you eat the overlord meal! And rob and threaten!"

With that, Su Wu walked out. Ye Chengfeng, who was behind, saw that something was wrong, and hugged Su Wu like a fly.

But who would have thought that Su Wu threw him away. Ye Chengfeng lay on the ground and looked at Su Wu in surprise, but he knew how powerful Su Wu was before, he hadn't seen him for a few days, and Su Wu was able to break free from him.

"What do you say you want me to do?" Seeing that Su Wu was about to go out, Ye Chengfeng yelled, he didn't want others to know that he was here.

Su Wu stopped, turned his head, and smiled wickedly at Ye Chengfeng. Ye Chengfeng suddenly felt uncomfortable and had a pimple.

Seeing Su Wu walking towards him, he subconsciously retreated.

"Since you know a little bit about computers, then help me get a computer. "Su Wudao, if this guy doesn't know anything, he will really send Ye Chengfeng to the police station and ask the police uncle to send him home.

This kid Su Wu felt that his brain was a little problematic, and his ability to handle things was the same as that of a child, and he couldn't see the appearance of a young man in his twenties at all.

After getting Ye Chengfeng, Su Wu paid another month's fee, and by the way, he asked Ye Chengfeng to buy a high-end notebook. This guy is actually very useful, since even the system of the cultivation room can be invaded, he knows that the system of the cultivation room is studied by the top talents of the country.

When he got home, Su Wu took a look at the black technology watch, and the system had been updated.

Wealth value: 7.981 million

Strength: 14 pounds

Dexterity: 0.0021 Hz

Spiritual power: 0.0001 yuan

Constitution: 83 (undecidable)

Super Space: 0 (1 million/1 sq.m.)

Inquiry: 50/person

Upgrade materials: 1,000,000 wealth (completed), a mid-level demon crystal, 10 catties of beginner-level demon beast meat.

Note: The system is upgraded, and the product can be hidden.

Seeing the newly added functions, Su Wu was stunned, what is the super energy space, it is too expensive.

However, he couldn't give up the child and couldn't trap the wolf, Su Wu's mind moved, and he hurriedly looked at the watch.

Wealth value: 6.981 million

Strength: 14 pounds

Dexterity: 0.0021 Hz

Spiritual power: 0.0001 yuan

Constitution: 83 (undecidable)

Super Space: 1 (1 million/1 sq.m.)

Inquiry: 50/person

Upgrade materials: 1,000,000 wealth (completed), a mid-level demon crystal, 10 catties of beginner-level demon beast meat.

Seeing that the wealth was worth a million less, Su Wu's heart was dripping blood, although this was virtual, but it could also help him refine his body!

However, in order to prove that he had not lost, Su Wu hurriedly tried how to use the super space.

After a long time, Su Wu was startled when he saw a book disappear on the desk in front of him, and then his mind moved, and the book reappeared, intact.

"Impossible!" Su Wu's heart trembled, this is not in line with the theory of science and technology at all!

But this is the case, Su Wu can only accept it, since it has appeared, then there must be a theory that it is in line with, and he can only blame himself for being lonely and unheard!

However, Su Wu had a bold idea.

System: At this stage, the Super Space cannot store physical life, please upgrade the system.

Su Wu's idea was frustrated, if he could put people inside, it would be really terrifying. However, even now, Su Wu felt that this black technology was very terrifying!

Who lost it? Why was it picked up by himself? A series of questions came up, Su Wu took a deep breath, Su Wu didn't think much about it, maybe it was really a coincidence?

Just like in the movie, the sandpiper and the clam compete for the fisherman's profit.

That's luck!
