Prince Xi felt that his heart was about to move.

Previously, he had always used the luthier profession as a means of controlling people's hearts, and rarely or almost did not use the sound of the piano to kill enemies.

This is determined by origin.

As a prince who was raised in the deep palace, had never been on the battlefield, and had always pretended to be weak, his ears and eyes were all about palace fighting methods, conspiracies and tricks to poison the like, and the matter of open fire was as far away as another world.

However, the monsters of the rock world made him realize that the enemies he had to face were non-humans.

They don't have a heart, they don't even have a mind.

The nod of the stubborn stone only exists in legends, and it is definitely not your character or virtue that can make it nod.

Only power!

The rock shakes, even on the verge of collapse, and its shape is unstable, which is why it gives people the illusion of "nodding".

Rough banging can't achieve this effect, but sound can.

As a pianist, he has dealt with sound all his life, but he didn't think of this truth for the first time, and the prince of Xi was ashamed.

After the weapon design drawing was in hand, Prince Xi immediately understood the principle.

He didn't show his abilities as a luthier in front of people, but that didn't stop him from studying in private and improving his sonic weapons.

Consumes less energy, almost two-thirds less.

The effective attack range is even greater - within 30 meters is effective kill, and it quickly decays after this distance, compared to 10 meters in the original version.

The original sonic weapon lasted for about 3 seconds, pausing for a few seconds after firing continuously for 3 seconds, while the improved sonic weapon of the Xi Emperor had a continuous attack of 10 seconds......

The first sonic weapons were put into real combat.

The prince and his staff carried heavy energy devices on their backs, and in their hands they held a long metal cylinder that looked like flamethrowers.

After discovering the rough-skinned and thick-skinned rock monster, more than a dozen people armed with sonic weapons immediately formed a fan shape, surrounded the rock monster in the middle, and immediately opened full fire.

The round mouth at the front end of the hand-held cylinder immediately emerged with a dense bundle of sounds, a bit like the sound of the engine when the plane took off, and a bit like the peak moment of the Qiantang River.

In short, it is a sound that surpasses the limits of human hearing, and even surpasses the limits of human hearing.

Under the fire of more than ten sound waves, the four-meter-tall rock monster rolled restlessly a few times, but it was a pity that its body was big and round, but its legs were still so short, it rolled one step, and the human race had already walked seven or eight steps, and it maintained a formation of surrounding the fire all the time.

With a roar of the dragon and impotent rage, the body of the rock monster finally began to "soften" and "deform", like grease on a hot pan, and it actually showed the flow of liquid.

10 seconds is instantaneous, but the humans have come up with the ancient three-stage strike tactic, and the firepower never stops, giving the monster no respite.

Whoa......

The big beads and small beads fall like jade plates, but the picture in front of you is not so poetic.

The rock monster collapsed almost instantaneously, without even a superfluous process.

It's like a wooden bar that has been bent to the limit, and there is no "click".

An egg-sized earthy yellow bead swirled and tried to burrow into the ground, but someone had already rushed up with a sapper shovel, and with a frantic digging, pulled it out.

"It's not small! Embryos that are the size of sesame mung beans are worth a lot more. ”

"Come on, this piece is worth a whole day's mining income."

"More production equipment, the most important thing we need now is manpower."

The production and improvement of sonic weapons immediately reached Xi Tong's ears.

This is what Xi Tong wants to see - the technology of the conqueror world is too low-level, and it is still in the stage of nuclear fission, and nuclear fusion has only just been touched, and it is not even comparable to the level of the earth.

But they have the advantage of being sensitive to military technology.

Like a round thing.

After the earthlings saw it, their first thought must be "this ball is big and round, it is better to sprinkle some cumin".

When the people of the conqueror world saw it, their first thought must be whether they could stone people to death if they threw it, and if they couldn't hit people on the spot, then stuff some explosives in it.

What if there is a 1 cm error in the shooting accuracy of the new weapon?

Normal people must be thinking about how to improve aiming, calibrate accuracy, and correct this 1 centimeter back.

Scientists in the world of conquerors will not be so troublesome.

Is it hard to add a detonation effect to a bullet? Isn't the explosion killing radius of 1 meter everything solved?

Just like the design of the E-class sonic weapon, when it came to the hands of this group of people, it immediately reached the level of D-level or even C-class.

Of course, there is the credit of Prince Xi, but the strong hands-on ability of others should not be underestimated.

Therefore, Xi Tong was very curious about what the technology of the Transformers would mutate into when it flowed into their hands.

Xi Tong doesn't mind giving Prince Xi more technology, provided that he can play with these technologies and bear fruit.

Plant a grain of millet in the spring, and harvest 10,000 seeds in the autumn.

At this time, the figure of the bumblebee fell from the sky, landed smoothly a hundred meters away from Xi Tong, and then walked a few steps and knelt down in front of Xi Tong.

"Master, this is the core of the just recycled."

The big box was full of indigenous creatures, the big ones were like basketballs, and the small ones were only as small as sesame mung beans.

Most of them were killed, and looking at the mottled sword marks on them, it was clear who did it.

There are also parts that are alive and conscious, and keep digging down, wanting to get into the soil.

Xi Tong glanced at the bumblebee, and his gaze seemed to fall directly on his core through the heavy armor.

However, Bumblebee is calm and does not hurt his emotions in any way.

Thinking about it, Bumblebee has been enlightened by Xi Tong and instilled by Luo Tianyi, and has already transformed into a new race - at least mentally.

The indigenous creatures of the rock world are not monolithic in the first place, there is neither the concept of a nation nor the identity of a race, all creatures are striped selves, how can they grieve for the death of their "kind".

Xi Tong nodded, and then released the earth spirit bead.

Click!

It was like stepping on a basket of eggs, all the cores were shattered, and the pure energy that escaped from them was devoured by the Earth Spirit Bead.

Along with it, there is also a trace of spiritual ideas that have infiltrated the will of the world.

It's negligible and almost undetectable, but it's not to be overlooked.

After all, this is the last existence of the will of the world, and it is also the root of the growing will of the world.

After absorbing it completely, the Earth Spirit Bead spit out a golden mist, permeating the radius of a hundred steps around Xi Tong's body.

Immediately, the ground slowly shook like boiling water.

One round core after another arched out of the soil, and he looked at the creatures in front of him with crystal eyes.

Although the bumblebee is huge, it is no different from mud, sand and rocks, and around Xi Tong, it is simply the glow of rotten grass under the bright moon.

The newborn stones were all looking at Xi Tong, and the first moment they were born, Xi Tong's figure had been deeply seared into their souls and origins.

Xi Tong turned to look at the harvest he had sown and smiled.

The Buddhist scriptures say that the sky is falling and the earth is surging golden lotus.
