My magic weapons are all rule-based

Xu Shan was in the Tianxiahui training ground.

There was no one around, and he had sent them all away in advance.

People had been sent to investigate the loud noise of the teleportation camp.

There was basically no other interference now, and the surrounding environment was safe.

There was only one thing he needed to do urgently.

Confirm the new prop, the boomerang.

This prop was only used once on Chen Zu, and its only feature was to hit the face.

It only hit the user's face, but he had not confirmed the specific power.

Now he finally had time to confirm it carefully.

The boomerang appeared in his hand, and Xu Shan observed it carefully several times.

He did not find anything special, so he threw it out.

The boomerang flew away, circled around, and automatically turned back, hitting his face.

Xu Shan raised his hand and swung again.

The boomerang was hit again.

When it turned back again, Xu Shan did not dodge and let the boomerang hit his face.

Xu Shan touched his cheek, picked up the boomerang and threw it again....

After trying three times in a row, Xu Shan was thinking hard while holding the boomerang.

He had basically figured out what this thing was.

First, the holder threw the boomerang, and the boomerang would automatically attack the holder.

The return force is the force of the initial throw.

If it is blocked, the force of the second attack will be superimposed on the force of the first attack.

And so on...In short, it will eventually pull back with the same force as the total force used to hit it, and it will not stop until it hits the face, otherwise it will never stop.

Before it hits the user's face, he can't even take back the prop actively.

But the problem now is, if one person throws it out, and the second person intervenes and hits the boomerang in the middle.

This...how to calculate it?

Thinking for a few times, Xu Shan took out the Poké Ball and summoned Lu Xiangjun.

This kind of problem can't be figured out by thinking, it can only be tested by trying.

A red light flashed.

As soon as Lu Xiangjun appeared in the training ground, she immediately shook her head left and right.

Seeing that only Xu Shan was there and no outsiders, she breathed a sigh of relief.

Walking up to Xu Shan, she hurriedly asked: "Junior brother, what's going on? Where is this? Have you come out of prison?"

In prison? It was a long time ago... But it's understandable that Lu Xiangjun didn't know.

I don't know what he is doing in the Poké Ball.

"Well, it's safe now. I have taken care of the matter. I will tell you in detail later... By the way, what have you been doing in my ball for so long?"

"Safe?"

Hearing this, Lu Xiangjun was completely relieved and answered casually: "Nothing, you have a strange box in there that can control the little man, and I have been playing with that little man?"

"What little man?"

"Uh, it's that dēngdēngdēngdēngdēngdēngdēng... Forget it, why are you asking me this, what's the situation, where is this?"

Absolutely, there is also Super Mario to play, much more comfortable than me.

Xu Shan scratched his head: "Well... this is in the Tianxiahui in Nanjiang."

"Tianxiahui... you mean the Tianxiahui of Zhenhai Xiejun?" Lu Xiangjun's expression gradually changed, "How the hell is this safe?"

"Calm down, Taigu Pavilion has always been a little wary of Tianxiahui, I was sent here to spy on the news... Actually, I have some status in it, you don't have to worry."

"Fuck, Junior Brother, you really can get along everywhere!" Lu Xiangjun widened her eyes and whispered, "Then have you seen Zhenhai Xiejun, what does he look like?"

"No, he is not often here... Don't ask for now." Xu Shan picked up the boomerang, "Come on, throw this out, use ten kilograms of force."

"I locked you up for so long, and when you came out, it became like this. You made me so confused... What do you mean?" Lu Xiangjun picked up the boomerang and threw it out.

The force was just right, just ten kilograms.

This level of power control is very simple for a Jindan cultivator.

Seeing the boomerang flying back, Xu Shan decisively hit it away, and waited for it to return for the second time, and then hit it again.

Lu Xiangjun was confused: "No, what are you doing?"

"Don't move, don't move, just let it hit you, you won't get hurt." Xu Shan said, and stepped forward to hold his arms to prevent him from making a move.

Seeing the boomerang coming towards her face, Lu Xiangjun's pupils contracted and she exclaimed: "Junior brother, you..."

Pah! Pah!

Before Lu Xiangjun finished speaking, the boomerang had hit her face.

Each of them was slapped.

Looking at the boomerang falling on the ground, Lu Xiangjun was confused: "No, what do you mean?"

"No, how much force did this thing hit you in the face just now?"

"About thirty kilograms."

Xu Shan's mouth twitched slightly.

It also hit him in the face with thirty kilograms of force.

He intercepted it twice with ten kilograms of force.

The effect of the boomerang was completely understood.

During use, no matter who touches it, it will hit them in the face fairly, and it will never miss anyone!

And all the forces applied to it will be accumulated.

It should be said that this boomerang is quite fair...

Very strong... It is definitely a super strong weapon!

As long as there are enough spiritual crystals and enough spiritual power support, he dares to kill even gods!

Thinking of this, Xu Shan suppressed his throbbing.

It is powerful, but the problem is that the biggest difficulty of this thing is how to make the opponent use it.

It's impossible for him to be beaten together with his opponent, that would mean both sides would perish together...

No, it can't be considered as both sides perish together. He suffered more, the boomerang consumed his spiritual power.

The greater the accumulated power, the more spiritual power consumed.

It's not easy to make the opponent use this weapon...

"Got it."

"Got it? What do you mean got it? Junior brother, what are you doing?!" Lu Xiangjun asked angrily, "You have messed me up from the beginning to now, can you please explain it clearly."

Xu Shan came back to his senses, took out the Poké Ball and smiled at Lu Xiangjun: "Senior brother, please go in again, I will explain it to you later."

"You..."

A red light flashed, Xu Shan ignored Lu Xiangjun's objection, directly put it into the ball, turned around and left.

.....

On the empty training ground, as the red light shot to the center, Lu Xiangjun appeared again.

Xu Shan hid in the house, peeking through the crack of the door.

Lu Xiangjun stood blankly in the training ground, her heart in a mess.

No...Where is my junior brother?

It's only been less than an incense stick of time, how come my junior brother is gone, and now I'm the only one left!

"Junior brother...Junior brother, where are you, don't scare me!"

Lu Xiangjun shouted in panic, looking around.

Suddenly, her eyes fixed on the ground.

There was a pile of V-shaped spiritual stones on the ground.

Lu Xiangjun picked it up without thinking.

When she got the spiritual stones, she felt something was wrong.

Lu Xiangjun was slightly dazed.

Something is wrong, this seems to be the weapon used by my junior brother just now, why is the surface covered with spiritual stones?

There is something on the back, what is it?

Lu Xiangjun instinctively turned it over to check.

On the back of the boomerang, there were densely packed special small darts, and it seemed to be stained with something else.

Lu Xiangjun's head buzzed, as if struck by lightning!

I...he...aren't these the things collected by my junior brother!

"Fuck!!!"

A scream echoed through the training grounds, and the boomerang was thrown hard into the distance.

.....
