Chapter 28： Unlock the mystery shop

When he got home, Cheng Xufan started alchemy without even bothering to eat. The metal droplets around him showed his inner restlessness.

"It's done."

Looking at the 114g golden sphere in front of him, Cheng Xu couldn't hold back his excitement any longer, and put it all into his portable space.

Although this 100 grams of gold does not belong to Cheng Xu now, the sum of the money and gold in his hand is enough for 100g of gold, and he can now complete the task to unlock the reward. Of course, he does not want to wait for several days.

"Task requirements: get 100g gold [completed]"

"Quest Reward: Mystery Store [Unlocked]"

Hearing this pleasant sound, Cheng Xu couldn't wait to open the system panel.

Gold: 37.1g

"Sure enough, I deducted 100g of gold, not 100g."

Cheng Xu thought about this possibility from the beginning. If he only had it, he would go to the gold shop and complete the task.

Then see the mystery shop he cares about most.

"It is detected that the mysterious store is unlocked for the first time, and the appropriate item reward is now given according to the host's situation."

Cheng Xu is happy, and there are free rewards. If everything in the store just unlocked needs to be exchanged for gold, then Cheng Xu still gets nothing and has to continue to save gold.

"Reward: [Titanium-based composite material formula and production method]"

Looking at the system reward in front of him, Cheng Xu fell into contemplation.

"Is this reasonable? How to reward such a thing?"

After thinking about it, Cheng Xu still accepted this fact. After all, this ghost system is unscientific and has a hint of science.

He thought about this question from the very beginning, why does this system require him to collect gold? Is it because gold is valuable? Obviously not.

Naturally, he also learned about the birth of gold, and understood that gold is actually a very scarce resource in the entire universe.

It is produced first from the supernova explosion, and second from the gold element formed at the beginning of the big bang.

Therefore, he has always assumed that the system is a certain future high-tech product.

In this case, the mystery shop rewarding new material technology also seems to make some sense.

Moving his mind to the reward, Cheng Xu suddenly felt that countless information poured into his brain. If he hadn't been using his abilities to exercise his mental strength during this time, I'm afraid he would have passed out of a coma.

The information transmitted into his brain was not as powerful as in the novels he read, which made him understand everything at once, and can do everything.

Rather, it was like an extremely clear memory stored in his mind. He could quickly extract every paragraph and every data in it, but he couldn't really understand the principle yet.

"Is this putting a big paper in my head?"

Cheng Xu tried to learn this knowledge, and found that there are a lot of professional terms in it, and it was daunting to look at.

Cheng Xu, who is already a junior, has naturally read a few professional academic papers. In fact, it is not something that you can read and understand when someone puts it in front of you.

It is often encountered that it takes more than ten minutes to read a sentence of dozens of words to understand it.

"No, this thing can still be like this?"

Cheng Xu found that when his thinking concentrated on a certain sentence, the annotations and explanations of all the nouns in the sentence would immediately appear in his mind, and the effect was comparable to that of a backgammon reading machine.

Cheng Xu, who already loves learning new things, is now a treasure, and instantly feels that this reward is so suitable for him.

He roughly scanned the properties of this new material. In fact, there are already some materials in the field of materials science. It originated from titanium alloys.

Although the properties of titanium alloys are very strong in all aspects, due to the high temperature requirements of titanium alloys, they cannot play a good role in many situations. received extensive attention.

Simply put, this thing is an upgraded version of the materials currently used, with higher strength and lower manufacturing costs.

Don't look at these strengthening values, which are only about a dozen points, but it is already a major breakthrough in materials science, not to mention its manufacturing cost has been reduced.

Cheng Xu looked at the other items unlocked by the mysterious store.

【Formula and production method of new graphene material】

Exchange: Gold 1500g

......

pull all the way to the back

【Design Plan of Satellite Weapon】

Exchange: praseodymium 10000g

【Controlled Nuclear Fusion Solution】

Exchange: Plutonium 50000g

"Damn it! What kind of stuff is this? He didn't know about praseodymium, he only knew that it was an element, but he knew plutonium. This stuff was made of atomic bombs. He even checked the price, and it cost more than six million dollars per kilogram. ."

"Forget it, it's important to eat, and then see if I'm going to be hungry."

Cheng Xu knew that it was not a matter of time and a half to fully grasp this information.

Of course he could write this information out by dictation, but just think about this kind of thing. How would he explain it if he really took it out?

It's like making a math problem but you can't understand the process of writing it yourself. The teacher knows that you copied the answer without thinking.

But where did the answer come from? Where did he go to explain it, so he still felt at ease and turned this information into his own knowledge.

The top priority now is to hurry up and cook. He is already hungry and his chest is on his back.

While reading the video of the dancing of the young lady, I gulps down the rice. I have to say that it is the most relaxing time when you don't have to use your brain.

"Combining work and rest, I'll go wash the dishes after watching the last video."

after an hour.

"Forget it, I'm a little sleepy. I wake up and wash the dishes."

In the evening, Cheng Xu, who had already gone to bed, suddenly wanted to keep a journal and recall what he did today.

"Look what happened today."

......

Looking at the log he listed, Cheng Xu couldn't help feeling a little satisfied.

"I really love studying too much. Most of the things are studying these materials. Go to bed. Tomorrow will be another day full of hope."

As usual, Cheng Xu got up early and finished running, took a shower, took a pot of water, and went to the yard to burn it on a coal stove. Compared with drinks, he was actually more accustomed to drinking plain water.

Turn on the gas stove, boil the water in the pot, put the noodles in the inside, the eggs in the inside, cook it out of the pot and add the seasoning.

But before he could take two bites, he heard some familiar and nauseating voices.

"It's really not over, come again?"

As soon as Cheng Xu opened the door, he heard scolding and the sound of the iron door being kicked.

"Little bastard, open the door for Lao Tzu, and I'll come to you every day if you don't come out."

"It's a real punishment, there are new characters appearing this time?"
