I let you cultivate immortality, not bring harm to the immortal cultivation world!

Late at night!

The prime minister stood alone in the study, the orange light burning quietly.

Tang Aotian's death was a big deal, and all the maids and guards in the mansion were busy in the front yard.

"I've said it before, Qin Yu is not that easy to kill!"

A voice suddenly came from the shadow behind the bookcase, and a moment later, a man in a black robe came out.

The prime minister sighed: "I wanted to use Tang Aotian's hand to get rid of Qin Yu, even if Xuantian Sect came to the door, I could just send Tang Aotian away."

"But I didn't expect that Qin Yu still had some skills."

His tone was full of regret for the failure of the plan, without any reluctance to Tang Aotian.

The man in black robe sneered: "The Prime Minister is so bold that he actually let his son be the scapegoat!"

The Prime Minister sneered: "He is just a waste."

"If you want to kill Qin Yu, there is only this way, unless...you can send out two people in the Tribulation Period!"

"Heh, that's impossible!"

"Deputy Sect Leader Xu has taken action once, and now he is in seclusion in the cave. If you ask him, he will only say one sentence."

The Prime Minister asked curiously: "What words?"

"There are many people in the Tribulation Period outside!"

The Prime Minister changed the subject without changing his expression. At this time, whoever is not in the Tribulation Period will be embarrassed.

"If you want to kill Qin Yu, you can only take advantage of the opportunity that Xuantian Sect wants its disciples to die and then train them."

"It's a pity that in order to maintain my personality outside this time, I have offended Xuantian Sect. During this period, I have to shrink my power in the court."

"Don't meet recently, so as not to be discovered."

"Okay!"

......

Early the next morning, Qin Yu went to the central square of the outer gate.

The house arrest only prohibits Qin Yu from leaving Xuantian Sect, and does not restrict Qin Yu's freedom in the sect.

Qin Yu posted his task and offered a price twice as high as the task reward.

There are also many strong men in the outer sect. There must be brave men under a high reward. Qin Yu believes that someone will take up this task soon.

Qin Yu went to the Refining Peak for nothing at the moment.

The little gadget he thought of on a whim was still being made here, and he wanted to see the progress.

Qin Yu quickly found Shi Yi of the Refining Peak.

The other party was still knocking on something in the studio, so Qin Yu did not rush up, but waited until the sound inside stopped before knocking on the door.

"Brother Qin Yu, you came just in time!"

Shi Yi greeted him enthusiastically. After all, Qin Yu was now his client, and he had to serve him well.

"How is the weapon I requested a few days ago?" Qin Yu asked.

Shi Yi handed Qin Yu a small ball that was still warm.

The small ball was only the size of an egg, and a layer of formation was engraved on the outside, which looked extremely delicate.

Shi Yi introduced: "Brother Qin Yu, according to your requirements, this ball is made of 32 sharp fragments, hollow inside, with a layer of enhanced array on the inner wall. As long as the internal force breaks the array, the 32 fragments will be like 32 swords, becoming a killing weapon."

"At the same time, each fragment is engraved with a defense-breaking array, which maximizes the power of this weapon."

Qin Yu looked at the small ball. The 32 fragments were angular, and the edges looked polished and extremely sharp. The material looked like iron.

"It looks good. I'll go back and try it. If it works, we'll start mass production!"

"Okay!" Shi Yi smiled.

......

Qin Yu brought the small ball to the bottom of the cliff where he fell before.

'Before falling off the cliff, I could only ask for help, but now I can fly the sword. I'm really awesome! '

Qin Yu took out the iron ball, and through the ability of the water spirit root to manipulate water, he converted the water molecules in the air into spiritual water and introduced it into the small ball little by little.

There are tiny gaps between the fragments of the small iron ball, but it does not affect the final power.

But Qin Yu encountered a problem, that is, the formation on the inner wall of the iron ball blocked the entry of water vapor from the outside.

Fortunately, Qin Yu is also a half-baked formation master, and he immediately used his spiritual sense to slightly modify the formation.

After a while, the formation became a one-way formation that can enter but not exit.

'This is a loophole, and Shi Yi needs to pay attention to it at that time. '

Qin Yu continuously infiltrated water vapor into the inside of the iron ball, and stopped only when the iron ball was half filled with water.

This also took Qin Yu more than two hours.

'It's a bit strenuous, next time let Shi Yi leave a small hole between the fragments. '

Qin Yu wrote down another modification suggestion.

"Next, let's try the power of this small iron ball!"

Qin Yu was a little looking forward to it. He had a vague hunch that the power of this small iron ball was definitely not weak.

Qin Yu put the iron ball on the ground, and then the whole person retreated, retreated, and retreated again.

The attack range of this small ball is 360 degrees without blind spots. Qin Yu dared not get too close before he understood its power.

Until Qin Yu retreated three kilometers, this was the maximum distance that his current mental power could control the fire element.

‘This distance should be enough! ’

Qin Yu thought, and caused the spiritual fire in the air to collide fiercely with the spiritual water in the small ball.

Instantly!

Under the extreme high temperature!

The spiritual water in the small ball instantly expanded thousands of times, and the huge force easily broke the binding formation on the inner wall and evenly transmitted to the thirty-two iron sheets.

With a loud bang, thirty-two pieces of iron were bombarded in all directions. Each piece of iron was turned into an afterimage, and sonic booms were heard wherever they passed.

Qin Yu's brows jumped because one of the iron pieces was heading straight towards him.

Qin Yu immediately used Xuantian's footwork to dodge behind him, but the speed of the fragment was too fast, and he was already in front of him in the blink of an eye.

Pfft~

The fragments blasted into the rock wall behind Qin Yu and sank deeply into the rock.

Immediately afterwards, Qin Yu heard a roar, which was a sonic boom caused by the fragments traveling too fast.

The speed of the fragments exceeds the speed of sound, so the fragments arrive first and the sound comes later.

Qin Yu swallowed, took out a healing pill from the Qiankun bag and swallowed it.

The wound on the shoulder began to heal at a speed visible to the naked eye.

"This... this is too powerful!"

"If I had this thing in my hand when I was being chased, I wouldn't have to run away at all."

Qin Yu murmured in disbelief.

He was three kilometers away from the iron ball. At such a long distance, he didn't even have time to dodge, and the iron piece easily broke his defense.

If it were detonated at close range, the force would damage the Nascent Soul.

‘Is this the horror of elemental spiritual roots? ’

This ball can erupt with such terrifying power, all because of the intense reaction of spiritual fire and spiritual water.

If it were replaced by ordinary water and fire, it would never reach this level.

And just now Qin Yu felt that before part of the spiritual water could turn into water vapor, the formation inside the small ball broke.

There are two reasons. One is that the formation is too weak.

The second is that Qin Yu's control over the fire element is not strong enough to turn all the spiritual water into water vapor instantly.

'If the internal formation is enhanced, or if I take a step further in controlling the energy of the fire element, the power of this small ball will probably be even greater. ’

‘And this is only the case where half of the spiritual water is injected. If it is filled with spiritual water, even the transformed spirit can break through the defense. ’

Qin Yu thought happily for a moment, and immediately took out a small notebook from the Qiankun bag, crossed out "Start cultivating immortality by practicing hard" on it, and changed it to "Start cultivating immortality by using steam"!

If you learn mathematics, physics and chemistry well, you will not be afraid of traveling all over the world.
