Shi Lei drank two glasses of cold water before he finally calmed down his extremely annoyed mood.

Re-opening the reputation system, Shi Lei directly entered the D-level exchange menu, and then selected the option to exchange 800 reputation points.

Under this article, Shi Lei quickly found the card of elementary physics mastery, and he immediately chose to redeem it.

Then, he entered the C-level exchange again, first under the 1,000 reputation exchange option, exchanged for the card of medium physical mastery, and then entered the 1,500 reputation exchange option to exchange for the card of high physical mastery.

Because of the painful experience of the damn S-level exchange, Shi Lei didn't bother to check that he had more than 10,000 reputation points, and after successfully advancing to the sixth level of the reputation system, what types of cards were added under the corresponding level exchange.

Anyway, tonight's purpose is actually these three physical mastery cards, and by the way, he also figured out the reason why Guteyi brought such a high reputation value before, after Shi Lei withdrew from the reputation system, he silently used the three physics mastery cards one by one.

After waiting for a few minutes, Shi Lei knew that he had basically become the most high-end physicist on this earth now, and there must be no obstacles to understanding the knowledge that Kong Fandong had instilled in him.

So, he recalled the data and knowledge about new energy batteries that Kong Fandong introduced to him, and soon, he determined that Kong Fandong's research institute, its research and development projects, once they break through the existing stage, will usher in a bright future.

Based on Shi Lei's current proficiency in physics, he easily judged that the final result of Kong Fandong's research institute's R&D project was that a battery pack of the same quality could store about 30 times the amount of power today. The most important thing is that the loss of power in the output process will be about 6% of the current battery technology.

What does this mean?

This means that as long as this technology is successful, the battery launched by Kong Fandong's research institute will be able to increase the range of those pure electric cars in the world today by nearly 40 times.

At present, in the world, the normal cruising range of mass-produced electric vehicles is two or three hundred kilometers, and a little better, it is only four or five hundred kilometers.

The battery technology of Kong Fandong's research institute can easily increase this endurance figure to more than 5,000 kilometers, and this is still on the premise that the quality is reduced by at least half.

And, of course, there's the increase in charging speed.

According to the announcement of a mobile phone, if you charge for five minutes and talk for two hours, Kong Fandong's technology can easily be charged for five minutes and talk for a whole day.

To sum up, Kong Fandong's current research and development, if the range of 1,000 kilometers is required, then the quality of the battery pack only needs about one-eighth of the previous one, which greatly reduces the burden of electric vehicles.

Judging from the charging process of this one-eighth mass battery pack, it only takes about the same charging time to fully charge the entire battery pack.

The service life of this battery pack will also be about doubled, and the electric vehicle battery pack, which is currently required to be replaced once every eight years, will be able to be replaced again in up to 16 years. In terms of the normal service life of the car, this can basically drive the car to the end of life.

The only problem left is the manufacturing cost of the battery pack.

With the current level of technology, if you want to mass-produce this kind of battery, you need to invest tens of billions in advance to complete a basic production line.

The cost of the battery pack produced is also as high as about 30 times that of today's batteries of the same quality. Even if only one-eighth of the mass is required, this means that for an electric car to reach a range of 1,000 kilometers, it would require four times the cost of the previous battery.

It seems that Kong Fandong is still a little too optimistic!

However, Shi Lei found a problem, he now, not only does he understand this knowledge, but even when he analyzes these data, he has begun to produce a series of solutions in his mind. Of course, these solutions also require a lot of experiments to be proven, but this made Shi Lei realize that he can not only analyze and understand all this, but also give them many very constructive suggestions in the future research and development process, which can greatly shorten the research and development process of those experimental scientists.

This seems to be a bit enjoyable.

Even if the funds invested in Kong Fandong are not enough to cope with his research and development, with the suggestions put forward by Shi Lei, Shi Lei believes that Kong Fandong's research institute will be able to help him complete all the research and development before the end of his loan term.

This is a package solution to all the problems faced by Kong Fandong.

At the same time, Shi Lei felt that it was necessary for him to renegotiate the investment conditions with Kong Fandong.

After all, the help that Shi Lei can provide to Kong Fandong now is not only financial, but also includes technical support. Of course, how to win Kong Fandong's trust still needs a process. However, when negotiating, Shi Lei had to add this entry.

And if in the next experiment, Shi Lei can not only help Kong Fandong complete the breakthrough in this research and development, but also help him better reduce the cost of battery manufacturing in the future, and even reduce the input cost of the production line, then this research and development achievement can almost directly take away the breakthrough of the Nobel Prize in physics.

Shi Lei suddenly felt a little excited!

After calming down, Shi Lei suddenly realized a problem, since after he learned the mastery of physics, he could obtain the ability to help Kong Fandong, then, if he went to exchange for the mastery of genetic science, wouldn't he still be able to help Ding Yu?

Although Ding Yu has made a breakthrough on his side, after Shi Lei has studied genetic science, he can help him better improve their technology. The bigger key is to reduce the cost of genetic modification. After all, the value of a technology is closely related to the technology itself, as well as the cost of implementing it.

Shi Lei finally realized the importance of various learning cards, which were previously considered chicken ribs in his eyes, but now they may become treasures for the entire human race.

It's just that Shi Lei has suddenly become a top scientist in physics, a top scientist in genetics, and a series of top scientists in chemistry, biology and so on, which seems to be a bit beyond the limits of human beings.

Will this cause an earthquake? Will Shi Lei become a guinea pig directly?

Belch......

I can't seem to do that.

Shi Lei found that he had to be leisurely, and he must not be so outrageous, after all, the result of going crazy like this is likely to be that Heika thinks that Shi Lei's behavior has touched its bottom line, so that humans on the earth may discover the secret of Heika, and finally directly erase Shi Lei, a super scientist who has ever been proficient in all disciplines.

After thinking of this, Shi Lei couldn't help but shudder, he found that he was really thinking too much.

It seems that if he wants to use the technology brought by the black card to help the earth shorten the process of climbing the technology tree, Shi Lei must also come up with a foolproof strategy, otherwise, he will only be greeted by the end of becoming a guinea pig.
