Yang Fengtian walked into the solar energy collection room, sat cross-legged, a large amount of light elements shone on Yang Fengtian's body, and then was greedily absorbed by Yang Fengtian's body, Yang Fengtian felt that the physical strength of his whole body was very abundant.

If it weren't for the fact that there were still more than two months left before the Ten Divine Academy was about to open, he really wanted to continue cultivating here, because a large amount of light elements would really help him too much, and it could greatly speed up his cultivation progress. However, he is mainly still cultivating the "Ducangran!Creation Sacred Technique" because a large number of light elements and spiritual power nourish his spiritual power, and the progress is very significant, and when it is time to recover his spiritual power, Yang Fengtian will have to look at the drawings and make scientific and technological products.

Even at night, Yang Fengtian entered the laboratory outside, still practicing, although the progress was slower, but it was not small, but he was not looking at the drawings at night, but reciting the "Complete Parts" and "The Complete Tools", which were deeply imprinted in his mind, ensuring that he would not look at these two books during the day.

......

Ten days later.

Yang Fengtian's hands were quickly assembling parts one by one, he was engrossed in looking at the small piece of iron, thinking carefully, every ten seconds his hands took out the parts from the silver barrels and assembled them.

After about ten minutes, Yang Fengtian suddenly had an extra silver glittering electric fan in his hand, but this electric fan was different. The silver fan was rectangular, and the only hole in it was a crack in the middle of the front, and there was no other gap.

Yang Fengtian took out a solar stone plate full of solar energy and inserted it into a card slot behind the electric fan. Then he pressed the on/off button, and there was no noise, but Yang Fengtian's surroundings were much warmer, although this laboratory was not cold in the first place (Dr. Hailong's technology was so advanced, wouldn't it be a piece of cake to build a cooling and heating equipment).

The material used in this electric fan is very ordinary, just the common fine iron, the only difference is that it uses a new science and technology inside, called "multi-energy conduction technology" by Dr. Hailong's planet, which is a kind of electricity that can convert electrical energy into temperature, this process will not make any sound, and the power consumption is very low, generally a solar slate can support it to run for ten days, you can imagine the practical value of this fan, assuming that it is put on the earth, it is also simple to become a billionaire with this technology.

This is Yang Fengtian from the drawings that Wei Wei took to make it, this is the last drawing. A stack of drawings, through Yang Fengtian's ten busy days, was produced, which can be described as really not easy. Now Yang Fengtian is basically doing this kind of small technology product every hour, of course, this is when he prepares the parts in advance, if he encounters more complex parts, it will naturally take a long time, but he has not encountered it yet.

This is a book written by Dr. Hailong before his death, called "The Light of Science and Technology", which introduces the scientific and technological products that Dr. Hailong has seen in his life, which have detailed introductions and production methods, the master now has the strength to read this book, I believe that the master will be able to make a lot of progress through this book. Then a familiar mechanical hand held a book ten centimeters thick and twenty centimeters long, and slowly moved to Yang Fengtian's face.

Yang Fengtian took it, but he didn't read it, but first cultivated the "Ducangran!Creation Holy Technique", which is not to say that Yang Fengtian is not interested in that book, but because his spiritual power is full, in order not to waste time, he went to the Ten Divine Academies to register within the specified time, so he can only cultivate first, after all, he can't read books when cultivating spiritual power.

Three hours later, Yang Fengtian finally finished his cultivation, he took the golden book of "Light of Science and Technology" and began to read it with relish. Open the book, the first page is crowded with the names of a large number of scientific and technological products, it is obvious that this is a catalog, but this catalog makes Yang Fengtian a little numb. After turning dozens of pages, I finally turned to the first technology product, this is called "weight scanner", which says: press the button to aim at the person to be tested, observe the screen, you can find out the person's weight, and it is also possible to test some objects, if you want to test the total mass of multiple people or multiple objects, you can double click on the home screen to lock.

Here's what to make parts, advantages, and drawings. Surprisingly, there is a drawing for every technology item, which is really very complete.

Yang Fengtian flipped to the catalog, looked carefully at the scientific and technological products on it, and suddenly he saw a scientific and technological product that he was more interested in, called "Purple Laser Pistol", he quickly turned to the page where it was, and he suddenly found that this was a scientific and technological product similar to the Earth Pistol, except that this was a laser, and it was very small, only half a cubic decimeter in size. There is a sensor on it that can be fired with a single hand press.

What is surprising is that the source of his energy is not solar stone, but a metal called purple iron, which seems to be a metal that can absorb ultraviolet rays. Yang Fengtian suddenly felt a little curious and was ready to make it.

But just when he was just about to make it, Wei Wei's words struck him like a bolt of lightning.

"Master, you can't make this thing now, do you see that there is a triangle in the upper right corner of that page! This represents that it can only be made by a creation that has reached the first realm of the "Ducangran! Creation Holy Art", because the core technology in it requires extremely strong spiritual power or decades of scientific experience to make it. The circle in the upper right corner represents the second realm of heaven viewing, and the heart in the upper right corner represents that it can only be made when the last realm is controlled. Wei Wei reminded cautiously.

Sure enough, Yang Fengtian was indeed split by Wei Wei, after all, this product is the one that excites him the most at the moment, but he does not have the ability to make it, I have to say that it is a sadness.

Yang Fengtian secretly shouted, I'll go! Hurry up and cultivate, why can't you reach that realm with so many restrictions!

Yang Fengtian quickly recovered his spiritual power, but this did not mean that he only did this one thing, because he felt that after these days of cultivation from the solar energy collection room, not only did his cultivation of the "Creation Holy Technique" greatly improved, but his spiritual power was also growing very rapidly, he felt that the spiritual power in his body was now very full, and he was getting closer and closer to the next realm of a one-star ninth-level scholar, it seemed that the difference was just a barrier, and it only took one accumulation to break through in one fell swoop.

Yang Fengtian's days in the laboratory, except for food, were basically local tyrant-level treatment. After all, Dr. Hailong has already built this place very comfortable for better research, but because of Dr. Hailong's death, the crops cultivated have long since died, so the only food here is mushrooms in the shadows, and various nutritious drinks converted from the spring water in the cave with a "drink preparation machine".

In fact, you can be full just by drinking drinks, because nutrients can be added to drinks at will, but Yang Fengtian is not used to drinking drinks as food every day, so he added a vegetarian fried mushroom, although it is also very monotonous, but at least it is much stronger than just drinking drinks.
