The disc soon began to turn, and then, stopped.

【Ding! Congratulations to the host for obtaining the skill item: Cosmic Sub-Intermediate Creature Skill Book, this lottery costs 10,000 reputation points, and the current remaining reputation is 108964. 】

Although he is somewhat disappointed, Zhao Ping'an is still happy to see the skill books, especially the skill books in this new field.

As the saying goes, knowledge changes fate, and he has been convinced of this since he received a reward of 100,000 yuan for his first idea.

"Let's put it first, and then come!" Zhao Ping'an was undoubtedly ready to use up the remaining prestige directly, but this time after clicking the start button, the disc did not rotate.

[Operation error: The current reputation value is not enough to conduct a lottery!] 】

"What the hell? Dude still has more than 100,000 prestige? Brother System, are you mistaken? Zhao Ping'an's eyes widened, and there was a hint of doubt in his tone, which felt like his own things had been hacked.

This time the system finally responded.

[Hint: 100,000 reputation is the benchmark value of a level 1 craftsman, and cannot be used for lottery consumption!] 】

[Warning: Conducting multiple draws within the same level will most likely cause the host to not be able to advance!] 】

[Reminder: The higher the level of the host craftsman, the higher the grade of the lottery items!] 】

Well, if this thing doesn't show up, it will send three messages directly as soon as it appears, and Zhao Ping'an will be stunned.

"I see!" After he nodded, he had a further understanding of the rules of the system, and at the same time he was thinking that his approach was really inappropriate, and it seemed that the use of prestige in the future must be reasonably arranged, otherwise it was very likely that he would lose the opportunity to get a higher prize.

In fact, there is one thing he is also very puzzled about, that is, how much prestige is needed to advance to level 2 craftsman, but it is a pity that the system refuses to disclose it to him, and he can only hope that it will not be too scary.

After figuring out these things, Zhao Ping'an clicked on the warehouse page and directly learned the 'Cosmic Sub-Intermediate Biological Skill Book', knowledge is definitely prepared, and it is natural to learn it immediately if you have the goods at hand.

A majestic wave of knowledge burst out in his brain like a spring, worthy of the sub-intermediate grade of the universe (although he still didn't understand how this grade was divided), and the content was indeed much richer than the previous two low-level skill books of the universe, making him feel a little dizzy in his brain, as if he couldn't bear it.

After spending a long time receiving this knowledge, his forehead was already slightly sweaty, and at the same time, a whole new world opened its doors to him.

In addition to a detailed introduction to the structure, function, occurrence and development of various organisms known to the earth, as well as the relationship between organisms and their surroundings, this cosmic sub-intermediate skill book covers a wide range of topics, including morphology, genetics, embryology, physiology, ecology, biophysics, biomathematics, cell biology and biomolecules.

There is no doubt that if Zhao Ping'an can absorb all this knowledge, he will definitely become the world's top biologist, and there is no one!

However, becoming a scholar is obviously not what he is pursuing, he has a small heart, and he has no idea of spilling his blood for the exploration of natural science, and just wants to make some money through this knowledge.

He always remembered clearly what Shen Mengyu said to him at the beginning - you must reach the height of Jack Ma within two years!

Two years, and now undoubtedly half a year has passed.

Will he be able to achieve this goal?

If it was two months ago, Zhao Ping'an would definitely answer: I don't know - these are three words derived from the huge pressure mixed with a hint of luck.

But for now, he will answer.

Not necessarily!

The success of friction charging technology has given him great confidence, and there is no doubt that if he was willing to sell, he would have been able to become a first-class rich man with a net worth of more than 3 billion yuan. But who would know that in fact, the birth of triboelectric nanomaterials was just a reverie generated from his experience of buying a mobile phone?

To put it in layman's terms, it was just a small idea from life, and he didn't think too deeply, so it wasn't his pinnacle work.

Zhao Ping'an has never been a diligent and studious child, if you ask him what he learned in physics and chemistry in junior high school, he will tell you two words with a cute face, and forget. Before he obtained the craftsman system, his knowledge of natural science can be described in four words - he didn't know anything about it. Therefore, he didn't know what level of development the natural sciences on the earth had reached, and he didn't know the meaning of the two 'Universe Lower Chemistry Skill Books' and 'Universe Lower Physics Skill Books' in his mind.

He only knew that as he slowly understood the knowledge, some strange ideas would often burst into his mind, and to be honest, if he was only designed for the sake of invention, he was sure that he could design a lot of novel things in a very short time, and maybe break the world record of 1093 inventions held by Thomas Edison in one fell swoop.

But Zhao Ping'an was reluctant to do this, the reason is very simple, the advantage of numbers may allow him to gain fame, but it may not bring him much wealth, and he still can't reach the height of Ma Yun, at least not in a short time.

I have to say that the three words An Ruoxi have become a kind of magic in his heart, maybe this is love, love for no reason.

So Zhao Ping'an's long-cherished wish is very simple, that is, to make money! And to design, you have to design the kind of product that can quickly accumulate wealth!

In fact, in the past few months, in the dead of night, he will always lie in bed and think about this problem, and there are some ideas in his head, and such a product should meet the three most basic characteristics:

First, extensiveness, must be close to people's lives of the product, so as to have the largest consumer group!

Second, uniqueness, which must be unique, at least cannot be replaced by other products.

In fact, rubbing mobile phones has also done this, but it is not good enough, after all, not everyone is very serious about the matter of mobile phone charging, if it is really not good, there are not too many portable power supplies on the market, and the cost is cheap.

So this brings us to the third point, necessity!

After this product is designed, it must be coveted by those who need it, and if conditions allow, it must be obtained! Even if there are no conditions now, we must work hard to create conditions in the hope that we will be able to get it in the future!

If it can have these three characteristics, then there is no doubt that this product will make countless money, so Zhao Ping'an has always admired Jobs, his iphone4 was infinitely close to this kind of product, after all, it was not uncommon to sell kidneys back then, but unfortunately it was only close, or failed to completely meet the standard.

So what kind of product can reach this height?

In fact, the promise is very simple, just in each of us, Zhao Ping'an faintly has a very rough idea.
