In the blink of an eye, it was seven days later.

The spirit points on the panel have increased a lot.

If you want to come up with a number, then Zhou Ye feels that the spirit points that die twice are enough.

Glancing at the cooling time on the panel, Zhou Ye became a little excited, and the incense was finally cooled down.

His movements began to quicken, and the seven hardened materials began to gather together and begin to merge.

Slowly, the seven immortal-level materials continued to fuse, and there were no accidents in the process.

At this moment, Zhou Ye's mood is still quite good.

He had this self-confidence, and with his refining ability, there would definitely be no accidents when the materials were fused.

Half a quarter of an hour later, seven pieces of immortal-grade material essence were smelted into black crystals the size of half a fist by Zhou Ye.

The black crystal is diamond-shaped, and the tip part of the two days is semi-circular to prevent stabbing yourself when using the crystal.

"The shape is complete, and the interior needs to be remodeled. ”

Zhou Ye muttered, and then began to transform.

He divided the interior of the crystal into two spaces, one very large and one very small.

The large space is used to seal the power of burning incense, while the small space has the power to seal the reincarnation.

Zhou Ye had already thought clearly, when he hit the sharp part of the diamond-shaped crystal hard, the two internal spaces slowly shattered, and after a while, the power of reincarnation touched the power of burning incense, and then if nothing else, the enemy would burp.

But this is all an assumption, what the specific situation will be, Zhou Ye still needs continuous experiments and improvements.

"By the way, precise guidance is required. ”

As if Zhou Ye remembered something, his divine thoughts poured into the crystal, and a miniature formation was carved in the crystal.

This formation is not very high-end and not very strong, and at the same time, it can't break out with any power.

The only use of this formation is to lock in.

As long as you lock the opponent with the formation when activating the crystal, the power of the crystal explosion will directly lock the opponent, either the power will dissipate, or the opponent will burp, which is so violent.

"Wait, should I add another thruster that automatically absorbs energy?"

Zhou Ye began to think.

There is no problem that can stump the brilliant scientists of Zhouda.

"The speed that a formation can provide for the crystal is certainly not slow, but it is a little difficult to chase the enemy, after all, the other party is not a fool, and the other party will also run away...... If one doesn't work, then add ten, and if ten doesn't work, one hundred, I still don't believe it. ”

Zhou Ye continued to struggle, constantly carving miniature magic circles on the inside and outside of the crystal, and even in order for the magic circle to work perfectly, Zhou Ye also dismantled some ninth-order materials to arrange those miniature formations.

"According to my assumption, after the crystal is activated, if there is the strength to support the operation of these formations, then this crystal should be able to burst out of the extreme speed of the peak of the Emperor Realm...... That's a bit slow. Zhou Ye shook his head slightly, a little disappointed.

In Zhou Ye's opinion, the complete state of the nuclear explosion crystal can erase the existence of the late stage of the Freedom Immortal and severely damage the peak of the Freedom Immortal.

If only the speed of the Emperor Realm is limited...... I definitely won't be able to catch up with each other.

"Fortunately, these formations can automatically absorb the spiritual energy of heaven and earth at all times, theoretically speaking, as long as the formation is within its service life, it can always maintain this speed and fly infinitely!"

Zhou Ye suddenly found that this design was simply amazing.

Anyway, this crystal must be the level of an immortal soldier in terms of hardness, and it is not clear what grade Zhou Ye is.

But after blessing the power of burning incense and the power of reincarnation, it is definitely not so simple to destroy this crystal.

When the time comes, once the enemy is locked in, he will have no choice but to flee.

It doesn't matter if the crystal can't catch up, you can fly slowly, anyway, the other party may not be able to destroy the crystal directly.

"I have to do things just in case, what if the other party suddenly gives me a kite flying style? One attack can't be destroyed, then two or three times...... So, you need to add an attack evasion formation!"

Zhou Ye continued his research.

This has not yet been integrated into the power of burning incense and reincarnation, and the entire crystal is full of formations inside and out.

This crystal with a pitch-black body can no longer be described in words.

Immortal-level materials may not be anything in ancient times, but in today's heaven and earth, they are definitely incomparably precious.

But this crystal used seven immortal-level materials at once.

If it weren't for Zhou Ye's wealth, it might have been really painful.

And the depicted formation also consumed a lot of good things from Zhou Ye.

"Well, it should be perfect now, right?"

Zhou Ye fell into deep thought, and he deduced in his mind what to do with this crystal if he encountered it.

After thinking about it, the only way to do this is to find a way to lock onto the crystal with your attack and destroy it, or use some artifact with a large area to block the crystal from chasing and killing, and make the crystal explode after touching the artifact.

"If that's the case, then it can't be changed to a delayed explosion, it should be changed to an instantaneous explosion, after all, the explosion power is too concentrated, basically narrowed within a range of ten miles, if the other party blocks the nuclear explosion crystal and then escapes, then with the current detonation speed of the nuclear explosion crystal, the other party will definitely escape to a safe place......"

After thinking about it, Zhou Ye began to modify the internal structure of the nuclear explosion crystal.

The nuclear explosion crystals must be made to explode the moment they are touched.

At the same time, in order to prevent operation errors, Zhou Ye will find a way to make a box and seal the nuclear explosion crystal inside.

In order to be safe enough, this box must be at the level of the Imperial Soldier, otherwise it will be blown up directly because of accidental shattering.

It doesn't matter if Zhou Ye is blown up, if he blows up his own people, there will be no place to cry when the time comes.

After some modifications, the nuclear explosion crystal was already relatively perfect in Zhou Ye's eyes.

"It's an experiment, let's give it a try. ”

Zhou Ye knelt down towards the nuclear explosion crystal, but sealed the power of burning incense in half an hour.

The nuclear explosion crystal didn't react too violently, and everything went very smoothly.

In order to be safe enough, Zhou Ye waited for the nuclear explosion crystal to stabilize for a while before slowly introducing the power of reincarnation.

Zhou Ye's eyes stared at the nuclear explosion crystal in his palm, and his heart was extremely nervous.

The power of reincarnation slowly flows into the narrow space that was deliberately separated from the nuclear explosion crystal.

When the reincarnation power enters it, because of the deliberate isolation, the reincarnation power cannot contact the power of burning incense at all.

"It worked!"

The nuclear explosion crystal in Zhou Ye's hand is sealed with the power of burning incense and the reincarnation of life and death!

When the two ends of the nuclear explosion crystal collide sharply, the internal structure will be damaged, and then the reincarnation power can detonate the power of burning incense in an instant.

According to Zhou Ye's assumption, if the peerless powerhouse in the late stage of the Freedom Immortal was in the center of the explosion, he would be wiped out by the power of the nuclear explosion crystal in an instant!

Even if you are on the edge of the explosion, you will end up seriously injured!

"Perfect!"

Zhou Ye laughed, and his smile became more and more presumptuous.

"Next, isn't it time to do a confrontation experiment?" Zhou Ye's eyes narrowed slightly.

He felt that he had to test the performance of the nuclear explosion crystal.

Everything that exists is theory, and it is necessary to practice to know the true capabilities of nuclear explosion crystals.

"Who are you going to do this experiment with?"

Zhou Ye touched his chin and thought about it.

That wandering spirit in the fairy world?

There's no way, you can't find where the other party is, and there's no way to lock the other party.

The Endless Black Lake?

This place is not proper, if it affects the stability of the small world, he Zhou Ye will become a sinner.

Zhou Ye pondered and meditated, but he could never think of a suitable venue for testing the ability of nuclear explosion crystals.

It's a little awkward.

Do you really want him to gamble when he uses nuclear explosion crystals?

What if the nuclear explosion crystal does not explode, or the explosion is not powerful enough?

"We have to experiment!"

Zhou Ye made up his mind, but the key point was that he couldn't find a place for the experiment at all.

"You can also experiment in the starry sky, but the effect is definitely not so intuitive......" Zhou Ye shook his head slightly, a little helpless.

"Or ...... Why don't you just use it to beat the heavens when the old brother of the king crosses the heavens?"

Zhou Ye touched his chin and thought.

Suddenly, a flash of inspiration flashed in my mind.

"Brother Tianwang lives in the Sunset Abyss, the Sunset Abyss is big enough and mysterious enough, I can conduct experiments in the Sunset Abyss, and I won't die at all, even if I enter the Sunset Abyss, who can stop me from resurrection?"

Zhou Ye suddenly laughed.

He carefully put away the nuclear explosion crystal, and then took out three ninth-order materials as the main material, and ten eighth-order materials as auxiliaries, and spent an hour refining a black box that could hold three nuclear explosion crystals.

The grade of this black box has reached the top of the ninth order.

In the past, the ninth-order top emperor soldiers, who symbolized invincibility, were now in Zhou Ye's hands, and they were just boxes containing nuclear explosion crystals.

"Top Emperor Soldier, the strength is enough, although it can't withstand the attack of the existence of the Freedom Immortal level, but there is no problem in preventing accidents. ”

Zhou Ye nodded secretly and put the nuclear explosion crystal into the black box.

Subsequently, Zhou Ye set off and returned to the wood realm.

Qingxu Mountain.

"I'm back!"

Zhou Ye walked into the courtyard with the black box.

The Infinite Heavenly Demon appeared beside Zhou Ye in an instant, staring at the black box in Zhou Ye's hand, the lid of the black box was transparent, and he could see the nuclear explosion crystal in the groove in the middle.

"This is the finished product?" asked the Infinite Heavenly Demon with narrowed eyes.

He was a little curious, was this thing that blew up the sun after it detonated?

Zhou Ye saw that the Qingdi and Lu Xiaoyuan both came over, nodded and said: "Yes, this is the finished nuclear explosion crystal, the two ends will explode after touching, it is very dangerous, the explosion power is concentrated within the range of ten miles, within the range, it can wipe out the late stage of the Freedom Immortal or seriously injure the peak of the Freedom Immortal, the farther away from the explosion center, the less damage...... After I have arranged a thousand propulsion formations, I can reach the speed of the limit of the Emperor Realm, can lock on to the enemy and pursue directly, can fly infinitely in the case of automatic charging, and can avoid the enemy's unlocked attacks...... However, these are all theories, and the specific effects still need to be experimented. ”

Although the Qingdi face was flat, there were already huge waves in his heart.

He knew that his life was sad, but now that he saw it, it was too sad!

The Infinite Heavenly Demon gasped and asked, "Then where are you going to do the experiment?"

"The sunset abyss. Zhou Ye replied directly.

Qingdi's face froze.

Just after blowing up the sun, it's about to blow up the sunset abyss?
