Wang Qing gradually clenched his right fist, and there was a crackling sound.

With strong willpower, Wang Qing quickly suppressed the throbbing in the depths of his heart.

Gentle Township is a hero's mound, his current strength is far from enough, and it is not the time to think about these messy things, working hard to become stronger is what he should do.

Glancing at the elves and Xia Lingyun in the training ground, Wang Qing asked them to train on their own first, and then walked to the research area that had just been set up today.

Geng Ghost Xiao Hei appeared, dumping a large amount of electronic components and some materials on the ground.

Today's main training has ended, and as Wang Qing expected before, Xiao Liu's performance is similar to that of Xiao Seed, and his personality is congenitally weak.

It's good to change the monster and change a little, and it is estimated that the progress of facing death should be very fast, but the temperament is a little casual, and there is no fighting spirit.

The Sun Ibu that Professor Bi lent him also has some problems, it is stronger than the weak character of Xiao Liu and Xiao Seed, but it is also limited, and the character has been finalized, and the effect of training is extremely poor, Wang Qing estimates that it will take about twenty days for Sun Yi Bu to pass the training of facing death.

But after all, it is Professor Bi's elf, and it will be returned in a month, and Wang Qing will go with the flow.

As for the other elves, Wang Qing was more satisfied.

Xiao Fei's strength has increased rapidly, and the growth he gets every day is visible to the naked eye, and the same is true of Xia Lingyun's big flower-eating Derpy, whose body is growing rapidly, and it seems that it is close to the next split.

In addition, Wang Qing's head iron dragon Xiaobao has finally evolved and turned into a crustacean dragon, Xia Lingyun's shuttlecock flower has successfully evolved into shuttlecock cotton, and the fluffy sheep is about to evolve into an electric dragon in the last two days.

After the evolution, Xiaobao is just like Wang Qing's guess, although he is still iron, but his IQ has increased a little.

It is not obsessed with flying, because it realizes that it can't fly, and it must have wings, so recently the iron dragon Xiaobao is thinking about putting a pair of wings on himself.

After the evolution, Xiaobao also knew that the fluffy sheep had been playing with it all this time.

For example, the former fluffy sheep used to create a trap on the ground, and it was even if it accidentally fell into it, and after crawling out, it was actually jumped down by the fluffy sheep, and jumped at least three times.

Yes, although the IQ has increased a bit after evolution, the head iron dragon Xiaobao is still not very smart.

At this time, the head iron dragon Xiaobao was thinking about treating others in the way of others, and decided to use his IQ to fool the fluffy sheep into jumping into the pit before it.

In short, although it is difficult for Xiaobao to get back to the field, the bond between Wang Qing and Xiaobao is clear.

In some ways, Wang Qing and Xiaobao are very similar, they both have a kind of persistence in trying hard to achieve their goals.

It is precisely because of this persistence that the bond between Wang Qing and Xiaobao has been strengthened a lot.

In addition, on September 1st, I saw the power of the dragon inspired by the body of the old king.

Wang Qing also vaguely felt that he could stimulate this power, and successfully stimulated it.

After using this power, not only can he use some dragon power, but he can even increase the strength of his dragon spirits.

It's too weak, though.

Moreover, this dragon power and the power of his holy light cannot be fused with each other, and there is even a trace of rejection.

Wang Qing didn't bother too much, just like when he gave up the flame power he had absorbed from the Hudi Gray Crystal.

The power of the dragon was also decisively abandoned by him, his current body has reached a bottleneck, and obtaining these miscellaneous powers, although it can make his strength temporarily stronger, it will make it difficult for him to break his limit.

In the long run, this will undoubtedly make him weak.

Without continuing to think, since the threat of the Sakura Alliance was approaching, and his main elf had fallen into a bottleneck, Wang Qing also began to develop the next hole card to prepare for the cultivation of the small fist stone.

There are already similar examples in another world, Wang Qing feels that if Xiaofist Stone can grow as it planned, and then carry out peaceful operations, destroy some important facilities, and some research bases, then there is a high probability that the Sakura Alliance will stop the war because of this.

Of course, the war will not be stopped, and the peace operation will need to be carried out several times, and then it will be up to Wu Li's communication software to monitor it.

Wang Qing quickly assembled some equipment into a huge storage box, and then took out a heavy box with a ten-kilogram metal ball in the box.

This is Wang Qing discovered some uranium veins near the Kunshan underground palace, and then purified the uranium-235 obtained, with a purity of about 97%.

In fact, the principles of peaceful weapons are not complicated, detonating devices, initiating charges, cylindrical uranium blocks, hollow spherical uranium blocks, guide troughs, neutron reflectors, neutron sources, timers......

Weapons of peace may sound incomprehensible, but the actual principle is exactly that, to put it bluntly, it triggers a chain reaction that causes uranium-235 to fission, releasing a huge amount of energy.

The only difficulty is that there is no natural uranium-235 ore in the outside world.

It's like a perfectly blended black powder mixed into a bucket of sand, and it is impossible to ignite the mixture of sand and gunpowder, let alone detonate.

Of the isotopes of uranium, only uranium-235 is active enough to cause a violent chain reaction.

As in the other world, uranium-235 is only about 0.7% in uranium ore, and if Wang Qing wants to make a weapon of peace, he must separate the isotope uranium-238 from uranium ore.

As for why Wang Qing knows that the content of uranium-235 is about 0.7%, this world is not a pure scientific world after all, and Wang Qing also has some means to detect it.

The data is used in the field by Xiaolu, and then by perceiving the micro things in the field, statistics (counting) it.

But it is not enough to detect it, the most important thing is to separate uranium-235, and only a concentration of uranium-235 above 90% can meet the minimum requirements for making weapons of peace.

And if you want to separate uranium-235, even if you have a field, you can't do it directly, or the efficiency is too slow, if you select and separate one atom at a time, this ten-kilogram uranium-235 is enough for Xiaolu to collect for a hundred years.

Uranium-235 and uranium-238 are isotopes of the same element, their chemical properties are almost indistinguishable, and the relative mass difference between them is also small.

The simplest way is to use a gas centrifuge to separate the two atoms by rotating at high speed more than 20,000 times per minute, and the two atoms will be separated because of their different weights.

In another world, if you want to make peace weapons, you need a lot of centrifuges, and this is also the way that some powerful powers limit the production of peace weapons by small countries - the amount of electricity generated by using a large number of centrifuges will produce a lot of heat energy, which can be seen on satellites.

However, in this world, Wang Qing has Xiaolu, and these ten kilograms of enriched uranium are the field of Xiaolu's utilization, which took nearly half a month to purify.

Unfortunately, even so, this is a bit of a thankless move, because if Midori lets go of his hands and feet, it only takes a day to cause more damage than a simple weapon of peace.

But some information I got from Professor Bi recently made Wang Qing's mind gradually active.

"Wang Qing, are you going to make something?"

Seeing Wang Qing take out a lot of discarded electronic originals discarded by Professor Bi's laboratory for splicing, Xia Lingyun, who had been practicing daggers for a while, walked over.

"Well, it's to prepare for cultivating the Little Fist Stone."

After Wang Qing finished speaking, he handed a document to Xia Lingyun next to him.

Xia Lingyun looked at the information and said: "The small fist stone of the electric system and the rock system, is this an elf similar to the ice six tails?" Are you going to modify a small fist stone of the electric system? ”

Wang Qing shook his head and said: "To be precise, it should be the steel system, in fact, this statement is not very accurate, it should be said that it is the metal system, and the relativity of non-metal elements, corresponding to the two sub-branches of the steel system and the rock system, which is written in the high school's "Laws of Nature", but it is not too detailed. ”

"Are you talking about this metal?" Xia Lingyun had just seen the metal ball in the box from a distance, but just as he was about to touch it, Wang Qing grabbed his wrist.

Wang Qing said: "Don't touch it with your hands, you can use your telekinesis to perceive it, this metal will produce radiation ...... the human body."
