Undertale starts with Sans' abilities

……

"Oh, I see.……"Yuan Shan answered nonchalantly.

He didn't believe Liu Yang would let them make such a thing, not to mention that it would be useless.

In this temporary period of peace, there was no need for such a thing.

Even in wartime, the one they made would be enough.

In fact, Liu Yang didn't want them to make something like an atomic bomb...

If a weapon with great destructive power like an atomic bomb was released underground, it would probably cause a lot of nuclear pollution.

……As for the ground, I will not consider it for now.

"Let's go see what's going on with Dr. Efes? The door there is very strong and should not be easy to break through."Yuan Shan said to Liu Yang

"good!"

……

Outside the laboratory, Liu Yang and Yuan Shan came to the door.

Several monsters possessed by hatred slammed the door... and the door of the laboratory was stable as expected, and it didn't look like it had been breached.

"I'll take care of it. The war machine is being repaired. Can you go and see how Dr. Efes is doing?"Liu Yang said calmly.���said.

Yuan Shan nodded, came to the front of the laboratory and teleported in.

The laboratory was very quiet. Yuan Shan came to the elevator and pressed the second floor.

The elevator door opened...

After waiting for a while, Yuan Shan successfully climbed to the second floor.

Yuan Shan followed his memory to Dr. Efes's work area.

After a few steps, he could vaguely hear the sound of typing on the keyboard.

As expected, Dr. Efes was busy in the work area and looked very anxious.

"Doctor, here I come."

Yuanshan picked up the work clothes beside him and put them on, then walked towards the direction where Dr. Efes was working.

"You...why are you here, Sans?"

"You were also attacked on the way?"

Yuan Shan was stunned for a moment. Attack? What attack?

Dr. Efes tapped on the keyboard and said,"It was those monsters outside."

"What about my brother?" Yuan Shan asked nervously.

"Papyrus? He's fine now, we lied to him that we had some important work to do. He's probably having a picnic on the ground right now!"

"call——"Yuan Shan breathed a sigh of relief

"Look, this is the information of those monsters."Efes stopped his work and pointed to the big screen in the center of the room.

Yuan Shan couldn't help but look up at the big screen, but……

……Nothing on the screen

"Doctor, this……？"

Yuan Shan wanted to turn around in confusion……

""Swish!"

A dagger stabbed at Yuan Shan's back.

Instantly,"blood" gushed out.

Yuan Shan knelt on the ground, touching the place where he was stabbed, gasping for breath.

"Doctor, how are you?……？"Yuan Shan said in shock.

Dr. Efes stood in front of Yuan Shan holding a dagger, his glasses reflecting white light, and the"blood" on the dagger was dripping.

"Haha, didn't expect that?"

"After that battle I invaded this body"

"The energy I have can only occupy this body with an important identity. I only need to defeat them one by one, and I can control the world in my hands."

"It's your turn next... Sans."

The possessed Dr. Ephis smiled smugly.

"What about my brother and others?" Yuan Shan asked anxiously.

"They are still traveling on earth. Don't worry, they will be the next to you."

"Ha ha ha ha……"

The possessed Dr. Efes played with the dagger for a while and slowly walked towards the original shirt.

"This knife is to send you away. As for the one outside the door, I will kill him in the same way and then parasitize him."

"What a perfect plan, isn't it?"

"Bye now……"
