Three days later, in a room in the highest-level underground laboratory, Richard carefully placed a whole thousand compound explosive blocks on the table into the spatial iron ring.

Stepping out, he walked out of the underground laboratory and appeared in the open space in front of the main laboratory in the Garden of Eden.

Here, Pandora, the old lich man Afu, and the eight-armed skeleton Anan are all there.

Among them, Pandora and the Old Lich Man are standing in front of a skeleton, discussing how it would be better to further transform it.

The eight-armed skeleton was in the distance, quietly looking at the dozens of new spell puppets that the old man had created during this time, looking like a gluttonous gourmand picking out pork belly at the butcher's shop, thinking about which piece would be more delicious after cooking.

The old man of the lich had obviously been wary of the eight-armed skeleton's actions for a long time, after all, he had been "patronized" by the eight-armed skeleton many times during these days. So, while discussing with Pandora, he glanced at the eight-armed skeleton from time to time.

As soon as he saw that the eight-armed skeleton was inclined to make a move, he immediately shouted unceremoniously: "Hey, don't touch it, don't touch it, it's mine! Stay away, if you want to find a bone, go to your own warehouse to pick it, don't rob me of the one I chose, ask for face!"

Listening to the old lich's words, the eight-armed skeleton withdrew his hand a little stupidly, but did not leave there. Still reluctantly hovering beside the spell puppets, looking patiently waiting for the old lich to relax.

Seeing this, the old lich man became more vigilant, glancing at the eight-armed skeleton more and more.

Richard took this scene into his eyes, and couldn't help but shake his head lightly, originally thinking that the old man of the lich and the eight-armed skeleton could coexist peacefully, form an Amnesia Alliance club or something, and huddle together to keep warm.

Now, it's almost impossible.

Actually, this is indeed a problem with the eight-armed skeleton, there are obviously a lot of purchased bones in the warehouse, why do you hold on to the old man's spell puppet?

Could it be that the bones that make up the spell puppets are a little different from the bones in the warehouse, and have undergone some changes?

Well, maybe it's really possible, and when you're done with this, you can try to study it.

Richard thought to himself as he walked towards the spell testing ground at the bottom of the sinkhole.

Pandora saw Richard, stopped talking to the old lich, looked at Richard and greeted him, and asked, "Hey, Richard, aren't you done yet?

"Hey, don't touch it!" the old man yelled at the eight-armed skeleton, then looked at Richard and asked, "Richard boy, you've been busy for almost ten days, what are you busy with, I still haven't understood." ”

"I'm going to test compound explosives. Richard said to Pandora, then looked at the old man of the lich and said, "As for the purpose of being busy, it is just to study a weapon, and now that it is almost at the end of the process, it should be successful in a few days." ”

"Weapons?" the old man of the lich asked, "What weapon?"

"It's kind of powerful. Richard knew that it would be difficult to explain it to the old man of the lich, so he simply said vaguely.

"Can that be used against the tree in the room that is locked up again?" asked the old lich, "I know that tree is subdued, but I always feel that it is not a good thing, and I may rebel again in your absence." If you can use that weapon, maybe it will save you some trouble. ”

Will it save some trouble to use nuclear weapons against Ximu?

I'm afraid that this is not a matter of saving trouble at all, and it is almost the same as destroying the entire Garden of Eden.

Richard couldn't help but smile bitterly in his heart, looked at the old man and said, "The use of my weapon is somewhat limited, and it is not suitable for dealing with Ximu. So, Mr. Afu, if you find a problem with the tin wood, it is easier to tell me in advance and let me solve it. ”

"It can also make the Garden of Eden safe for a while longer. Richard said silently in his heart.

"It's fine. The old lich man listened.

"Then you guys get busy first, I'll go. Richard said.

"Good. ”

"I'll see you later. ”

The Old Man Lich and Pandora each waved.

Richard stepped back to the spell testing ground at the bottom of the sinkhole, where the old man and Pandora turned to discuss the improvements to the spell golem, while the eight-armed skeleton stared at a pile of spell skeletons, waiting for an opportunity.

......

Spell testing ground.

Richard walked here, reached out from the spatial iron ring, took out pieces of explosives, and placed them around.

What he was going to do now was to test the explosives one last time to test the results that had been determined. If there is no problem this time, then we can put some finishing touches on the construction of nuclear weapons, and we can completely build nuclear weapons.

In order to ensure that there were no problems, he used twelve points of seriousness this time, and it took nearly half an hour to completely place the explosive block.

Compared to usual, this time it was a little slower than usual - usually once is only about twenty minutes - if it was shorter, it would be easier to go wrong, after all, the position of each explosive must be accurate to the micron, and the detonator used for detonation must be as exactly the same as possible.

Half an hour later, I saw a whole hundred blocks of composite explosives regularly arranged in an ellipse, each of which was connected to a detonator, which was equipped with an excitation structure, and the wires behind the excitation structure stretched out, and finally all the wires were combined into a strand that extended to a console dozens of meters away.

Everything is ready, only the east wind is owed.

Richard looked at it, nodded with satisfaction, and took out a model for testing from the spatial iron ring.

Unlike the previous model, in order to simulate the actual detonation of a nuclear weapon as much as possible, this model is no longer a simple stainless steel block, but a replica of the "Crystal Heart" metal uranium component.

The shape and dimensions are exactly the same as the original, and in fact even the material is the same - it is made of uranium.

The only difference is that the Crystal Heart uses the precious weapons-grade purified uranium-235, while the replica uses unpurified uranium metal - that is, most of it is the isotope uranium-238, and only a very small amount of uranium-235.

In this way, more than 99 percent of the simulations can be achieved, after all, except for extremely small differences, the physical and chemical properties of isotopes are almost identical—this is the knowledge that has been taught in middle school physics.

At the same time, because the replica contains only a very small amount of uranium-235 (less than 1%), no matter how much it is squeezed, it cannot reach a supercritical state to cause a nuclear explosion.

In short, a replica made of unpurified uranium metal is a perfect test target.

Perfect...... Richard said silently in his heart.

Richard held the silver-glittering replica, gently placed it in the center of the explosive, and after making sure that it was correct, he walked to the test bench dozens of meters away.

The last explosives test, begin...... Richard said inwardly, reaching out and pressing a red button on the console that connected the wires.

"Smack!"

"Boom!"

Almost at the same time as the button was pressed, a full hundred pieces of explosives arranged in an elliptical circle exploded at the same time, spreading the tremendous pressure towards the center.

The flames rose, and Richard's eyes flashed with a ghostly light, using the clairvoyance of the Gaze Eye to look through the flames and dust to the replica. I saw that the replica of the strange water cup was only squeezed into a cylinder by the blast wave of explosives in an instant, not much bigger than a human finger.

If it is uranium-235, it can definitely reach a supercritical state and cause a nuclear explosion in this state.

Very good...... A reassuring thought crossed Richard's mind.

As a result, before the thought could completely disappear, Richard's eyes shrank.

In his field of vision, he suddenly saw a faint wave of energy light, flashing on the surface of the test target that was squeezed into a cylinder, and then violently spreading.

This is?
