"The world is changing, the friendship is the same, and the atmosphere in the group is as harmonious and lively as ever. ”

Baili Qingfeng watched everyone quickly build a "cute new trembling" expression building in a joking tone, and said with deep emotion.

For two years, there was only their Golden Champion of the Golden Zodiac.

Baili Qingfeng glanced at the news that popped up on the whole site, and estimated the effect......

In a way, it is equivalent to announcing the world?

So I chatted with everyone in the group for a few more words and withdrew.

After closing the interface of the Tianji Palace, Baili Qingfeng looked at the time, although it was not very early, if he ran over, it would not take long to reach the laboratory in the Bikini Basin.

"Time is of the essence. ”

Baili Qingfeng stood up, went downstairs, and said to Shi Yiyi, who was about to prepare dinner: "Don't worry about me for dinner, I'll go to the laboratory first, there are some things that need to be dealt with over there, and when the matter over there is almost resolved, I will go to the Aurora Empire, do you have any specialties that I need to help you bring?"

"Aren't you eating?"

Shi Yiyi was a little disappointed, but still said: "Pay attention to your Aurora Empire, safety first." ”

"I will, it shouldn't take long, half a month soon, a month or two at the slow, and it will be able to stabilize over there in a month or two, even if I'm not over there at that time, it doesn't matter. ”

"Hmm. ”

Shi Yiyi nodded.

At that moment, Baili Qingfeng called Haisen, and then went out the door and headed in the direction of the laboratory.

Although the laboratory is more than a hundred kilometers away from Char, it is only twenty minutes away from the full speed of the hundred miles of Qingfeng, which is why he needs to be careful not to damage the flowers and plants, otherwise the efficiency will be faster.

At this moment, the strength of the laboratory defense seems to have risen again, and the garrison stationed here has risen from a company at the beginning, to a battalion, then to a regiment, and now, it has reached half a division, a full force of 8,000 men, which is enough to deal with any conventional danger.

Even if the ninth-level celestial people were not practical and fought and retreated, they would not dare to attack the base camp of the eight thousand modern elite army.

"Commissioner Hayzen. ”

Baili Qingfeng's figure flashed and appeared in front of Haisen, who was waiting for the door.

Due to the subtlety of the realm of heaven and man, and the fact that he deliberately reduced his speed when he was about to arrive, so that he only brought a gust of fresh wind.

"Chairman Baili. ”

Haysom greeted him with a smile.

And the soldiers at the door shouted at the same time after seeing Baili Qingfeng coming: "Salute!"

For a while, dozens of people were in unison, and at the same time saluted to Baili Qingfeng, their eyes were full of respect and heat.

In the battle on the northern border, Baili Qingfeng has been shaped into a legendary hero by the Xia Kingdom with all his might, and has a high reputation in the military department, and in the battle of Yandang Mountain, he defeated the impact of tens of thousands of cave people with the power of one person, which pushed his prestige to the peak, and even gradually mythologized, up and down the military department, his reputation is loud, even compared to Qiao Sen.

"You've worked hard. ”

Baili Qingfeng saluted back to these soldiers, and then followed Haisen towards the laboratory: "How much enriched uranium have you prepared during this time?"

"It's still a little short of your requirements, so far only 91.4 kilograms meet the standard......"

"Ninety-one kilograms......"

Baili Qingfeng nodded.

The number did not exceed his expectations.

After all, time is too short, even if he has a steady stream of raw materials to support him, and all sides are open to convenience, but efficiency is here.

Unless Baili Qingfeng is willing to expand production, otherwise, the output will not go up in a short time.

If the expansion of production is easy to cause the problem of leakage, once the matter here leaks out, I am afraid that the eyes of the whole world will be attracted to it, and he does not plan to build more uranium enrichment plants until he is sure to ensure secrecy.

"I see, how is the test equipment I asked you to prepare?"

"Preparations and assembly have been completed, and the reactor is fully operational. ”

"Alright, I'll leave the rest. ”

Baili Qingfeng Road.

At that moment, Hayson took him directly to a heavy water nuclear reactor underground.

On the battlefield of Tianque Mountain, when facing the cave people who were all over the mountains, Baili Qingfeng had a feeling that he had more than enough heart and not enough strength.

Fortunately, all the cavemen I met that time were the cavemen of Blood Wolf City, and these cavemen broke down when they saw them and fled quickly, but if the cavemen who attacked them at that time were not from Blood Wolf City, or if these cavemen of Blood Wolf City still chose to launch a death charge even in the face of themselves, even if he would be exhausted and out of breath after killing thousands of them, he would have to choose to retreat.

As soon as he retreats, the remaining cave people will surely flood Yandang Mountain like a tidal wave, devouring the 80,000 soldiers on Yandang Mountain led by the First Army under the command of Qiao Sen, and further spreading to the capital Hill's Light, destroying Hill's Light, resulting in tens of millions of casualties.

If that happens......

It's a human tragedy!

At present, the cave people of Tianque Mountain have not fled back, not only did they not flee back but also got strong reinforcements, the original 50,000 cave people, after a series of battles, only about 30,000 remained, after getting the second wave of support, the number of cave people has exceeded 80,000!

Moreover, more than half of the 80,000 cave people belong to elite warriors, regardless of combat strength, morale, and will to fight, they are far above the 50,000 cave people who were driven away by him before, and now they are gathered in Tianque Mountain and don't know what they are doing, but one day they will kill out of Tianque Mountain and sweep the Eastern Divine Continent.

As one of the countries bordering Tianque Mountain, if this kind of thing happened again, he didn't dare to guarantee that he would be able to repeat the miracle of Yandang Mountain.

In this case, he desperately needed some high-power weapons of destruction to deal a fatal blow to the 80,000 cavemen......

This weapon......

It fell on the heavy water nuclear reactor in front of me.

"Ninety-one kilograms of enriched uranium...... The utilization rate of uranium bombs is too low, the little boy used 64 kilograms of uranium, but because less than one kilogram was nuclear fission, the final power released was only equivalent to 15,000 tons of explosives...... The limit of ninety-one kilograms of enriched uranium is here, and the final equivalent cannot even break through the yield of 100,000 tons, which is too bad. ”

Because of this factor, what Baili Qingfeng wants to do this time is plutonium bombs.

The technical nature of plutonium bombs is much higher than that of uranium bombs, and the manufacturing process is prone to produce plutonium-240, that is, heavy plutonium, which is the same as plutonium, but has an extra neutron, which makes it highly radioactive.

And plutonium-240 will spontaneously fission, no neutron excitation is required, spontaneous fission randomly releases neutrons, and a careless manufacturing process will lead to early detonation, and once detonated in advance......

The results go without saying.

In addition to these difficulties, plutonium bullets are unstable in decay and are less conducive to preservation than uranium bullets.

But......

After Baili Qingfeng was built, he planned to throw it to Tianque Mountain, which was not conducive to preservation, but there was no need to consider it.

With the arrival of Baili Qingfeng, one order after another was transmitted, and suddenly, this huge heavy water reactor began to operate.

In the process of operation, Baili Qingfeng's spirit was highly concentrated, and through the spiritual perception of the Ten Levels of Refining God, the operation of the reactor was almost clearly exposed in front of his eyes.

At the same time, his spirit also permeated the reactor, trying to get a glimpse of the process of deuterium hitting uranium, witnessing the birth and decay of neptunium, and the final production of plutonium, but ......

In just a moment, he gave up.

"It's too fast, and the energy reaction involved in it is too violent, even if I have reached the tenth level of refining gods now, and my thinking speed has been significantly improved, if I want to observe and calculate this phenomenon, I still can't do anything, this difficulty is like how many raindrops have fallen in dozens of cubic meters on a rainy day. ”

Baili Qingfeng rubbed his eyebrows, and in just a moment, he felt that he was dizzy and his mental consumption was extremely amazing.

It's a pity that this kind of consumption is just a simple consumption, and it can't have a counter-shock effect on the mind, and naturally it can't achieve the purpose of refining the mind, otherwise......

Polishing your mind in this way will inevitably lead to a long time.

"Either my mental and computing ability can be greatly enhanced, or I can give the spirit 'tritium' attribute as soon as possible, otherwise, even if I have the ability to mentally interfere with matter, it will not be of much use, at best, I can only reduce the probability of failure of the experiment through observation......"

Baili Qingfeng thought to himself, but his mind was still focused on the heavy water reactor, observing the nuclear reaction between uranium and plutonium, and if there was any sign of a mistake, he would turn off the instrument as soon as possible to terminate the test.

Time passed, and in three days, Baili Qingfeng operated and produced more than 60 kilograms of plutonium.

Due to the relationship between the Miao family where the ethereal shrimp is located, he has already obtained the implosion-type detonation related equipment, and the next further production procedures have become a lot easier.

With the accurate observation and assistance of the Ten Spiritual Interference Substances of the Refining Gods, the entire manufacturing process was extremely smooth.

Of course, in order to pursue speed, radioactive substances, decay radiation, and the like are inevitable, but for Baili Qingfeng, who has already cultivated to the strongest level, this level of damage is not worth mentioning at all.

After all, this kind of negative energy only causes an impact at the cellular level, and what Baili Qingfeng is most afraid of is this kind of damage.

The observation and prevention of the spiritual realm itself is also able to move and move hundreds or thousands of kilograms of instruments at will, plus it has a wealth of knowledge accumulation......

Three days later, six plutonium bombs with a charge of 10 kilograms were successfully manufactured.

Looking at these six little guys who weighed only four tons, Baili Qingfeng held one in one hand and put them away.

After sealing the six plutonium bombs, he breathed a sigh of relief.

"Although once this weapon is used, Xia will immediately fall into the cusp and cause countless troubles, but it is better than being destroyed...... I hope that those cave people in Tianque Mountain can stay quietly, and it is best to wait for me to cultivate to the ninth order of the Supreme Strength...... Legendary creatures come out later, so that I'll be able to barely cope with Shia even if I'm in trouble. ”
