Lin Yu drew the internal structure of the earth-shattering thunder on rice paper.

The previous sky-shattering thunder was just the simplest structure, with black powder and shrapnel and leads.

But now Lin Yu has made all-round improvements to the Heaven-Shaking Thunder.

I've never eaten pork and I've always seen a pig run, so Lin Yu directly improved the Heaven-Shaking Thunder in the way of a grenade based on his own understanding.

Added a safety ring, a fuse plate, a firing pin, a fire cap, and a delay potion to the Earthquake Thunderbolt......

The delay medicine is similar to the firecrackers that children play with, the kind that will explode after three or four seconds.

Then there is the initiating charge and the main explosive.

Lin Yu listed them in detail......

"Breathtakingly, you don't need a fire breaker, pull out this so-called safety ring, you can make the earth-shaking thunder explode, and ...... What's more powerful?"

The male loser held the drawings in both hands, as if he was caressing his lover's flesh, affectionate and intoxicated.

Subsequently, the male loser sent someone to create the safety ring, fuse and firing pin fire cap on the drawing.

This kind of small thing, Tiangong Institute also completed the creation of three times and five divided by two, and took the lead in sending ten sets over.

Because Lin Yu also designed the earth-shattering thunder that could be detonated without the need for a fire fold based on his personal understanding.

The fire generated by the firing pin hitting the fire cap is enough to ignite the retardant charge, and the combustion of the retardant charge ignites the initiating charge, and the initiating charge ignites the main explosive to complete the detonation of the earth-shattering thunder.

Because of the successful experience of fireworks, Lin Yu still has some certainty.

Not long after, Lin Yu successfully packed all these newly added small things into a head-sized earth-shattering thunder.

and directly sealed.

There were seven or eight sets of assembly failures, so Lin Yu only succeeded in two sets.

With excitement and apprehension, the male loser took Lin Yu to the test hall.

This will be an epoch-making experiment.

Because if the Heaven-Shaking Thunder that can be detonated without the need for a fire break is successful, the Heaven-Shaking Thunder that Lin Yu envisioned to blow up the enemy camp thousands of miles away will definitely have the possibility of success.

Because if a sky-shaking thunder flying thousands of miles away still needs to ignite a lead, it is estimated that a sky-shaking thunder needs a lead hundreds of miles long.

What's the difference between this and waste?

Therefore, if this kind of sky-shaking thunder that can detonate itself is successful, although it is not enough to immediately bomb the enemy camp thousands of miles away, it can be regarded as a big step.

"Doesn't the Dean of Gong Yi invite the Heavenly Palace Masters to come over and observe?" Lin Yu suddenly looked at Gong Yu Zi and said.

"This ......"

The male loser was stunned at that time.

Then he understood, this was the moment when Lin Yu wanted the Heavenly Craftsman to witness the historic moment together.

So he immediately summoned the vice president Qingfeng, and summoned more than 1,000 heavenly craftsmen.

"That's good, these Heavenly Craftsmen are not ordinary people, absorbing a wave of their beliefs should be very helpful in improving their cultivation. ”

Lin Yu thought so.

In fact, he didn't want everyone to witness the historic moment at all, he simply wanted to absorb the power of faith.

In Lin Yu's view, a test explosion without the power of faith will be a failed test explosion......

He looked at the celestial craftsmen on the observation platform in the test hall, and a faint smile appeared on his face.

"This palace has always admired the dedication of the Tiangong Institute to the road, so when he had nothing to do, he casually created some gadgets. ”

Lin Yu paused for a moment, and then continued: "This palace may be the last time I come here in the next few years, so let's leave a small gift." ”

"Gifts?"

The celestial masters whispered, and a hint of anticipation appeared in their eyes.

Lin Yu lifted the improved Sky-Shaking Thunder and said loudly: "Presumably all of you Heavenly Craftsmen know that this Sky-Shaking Thunder was created by the main palace, and it used to need to go through cumbersome steps before it could detonate the sky-shaking thunder, but now, the improved sky-shaking thunder of the main palace only needs to gently tear off this safety ring, and it can explode directly......"

Lin Yu pointed to the ring at the top of the earth-shattering thunder.

"Unplug it and blow it up?hehe...... I'm afraid that the opponent didn't fall, but he fell first......"

Yang Qingfeng, who was defeated in front of Lin Yu one after another, laughed.

He didn't look at Lin Yu unhappy now, but simply thought that this was an unsuccessful improvement.

The other Heavenly Craftsmen exchanged their heads and ears, and they also felt that this would only make the Heaven-Shaking Thunder more dangerous.

Lin Yu glanced at Yang Qingfeng and smiled contemptuously.

Then, in everyone's wide eyes, he pulled out the ring on the earth-shattering thunder.

Everyone's hearts were in their throats, and even the male loser was so frightened that he wanted to protect Lin Yuquan.

But...... Yang Qingfeng's opponent did not fall, but the scene where he fell first did not appear.

Even...... Lin Yu calmly weighed it twice in his hand.

This scene almost scared the courage of the heavenly craftsman.

Three seconds later, Lin Yu directly threw it into the big pit in the test hall.

Subsequently......

There was a loud 'bang', and the earth was shaken.

The smoke cleared, and in the large pit in the test hall, there was a pit that was much larger than any other crater that had been blown up by the earth-shattering thunder.

The power is unfathomable.

Quiescence!

There was a deathly silence in the test hall, and a needle drop could be heard.

The male loser stared blankly at the deep pit in the test hall, and did not come back to his senses for a long time.

It worked!

Not only is it safe and convenient, but it is also extremely powerful.

Boom!

Yang Qingfeng collapsed to the ground again, and he was convinced......

The heavenly craftsmen of the Tiangong Academy had an incredible look on their faces, inhaling cold air.

This terrible scene completely subverted their imagination.

At this moment, the shock in their hearts far exceeded the fireworks created by Lin Yu.

There is no need for a fire breaker, just by relying on the earth-shaking thunder itself, it can complete the explosion.

In this way, it is even more effective than the magical power of the monk Wendao!

Who is Your Highness?

The brain melon seeds seem to be completely different from theirs!

Afterwards, Lin Yu felt the power of faith in the test hall, which swirled in the hall like a cloud.

Of course, this is only seen by Lin Yu alone.

So the nine-story glazed pagoda frantically absorbed the power of these beliefs, turned into a talent qi, and rippled in the fourth layer......

And Lin Yu's cultivation is also growing invisibly, and his strength is becoming more and more unfathomable.

It's a pity that Lin Yu never found an opponent.

Because he is His Royal Highness the Crown Prince, no one dares to fight him.

This made Lin Yu very distressed, because he didn't know how powerful he really was......

Is it really invincible at the same level?

After Lin Yu successfully detonated, the other one was handed over to the male loser, so that he could feel it for himself.

The male loser was excited and at the same time with strong expectations, he opened the safety ring of the earth-shattering thunder and threw it out......

Then the explosion effect was exactly the same as Lin Yu's, which completely made everyone in the Tiangong Academy boil.

And the male loser carefully put away Lin Yu's drawings, more cautious than holding the sage's heart.

"Your Highness, the old man can't accompany you more, the old man wants to study and study in person, you go down and let Cao Bai pick time to come to apprenticeship......"

After saying this, the male loser left the test hall in a hurry, leaving Lin Yu and a group of heavenly masters with a bewildered face......

"Dean, let's study together......"

The Heavenly Craftsmen were also extremely hot, they didn't expect His Royal Highness the Crown Prince to really give this improved Heaven-Shaking Thunder Blueprint as a gift to the Heavenly Crafts Academy.

Your Highness!

Subsequently, more than 1,000 people chased directly to the main hall of the dean of the Tiangong Academy......
