Rimbaud added: "There are two pens, capacitive pens, and I charge the pens."

Bai Chunian touched the solid wall in front of him. There was no grid on it. He took out his mobile phone and glanced at it. There was no signal, and taking pictures and posting questions would not work.

The puppet master asked, "Can the pen write on the door?"

Rimbaud tried it: "Yes, you can write black electronic handwriting."

There are actually two square grids in front of Rimbaud and Eris, displayed on the two doors, like two chessboards.

After discovering that the capacitive pen could write, Eris grabbed a pen and scribbled on the grid, drawing a stickman who was hanged, a stickman who cut his belly, a stickman who beheaded, in short, a stickman.

Rimbaud seriously wrote into the grid, 1234567... the entire grid was filled.

After a while, the grid lines flashed red, and a piece of paper was spat out inch by inch from the crack of the door. The paper fell to the ground and was picked up by Rimbaud.

It reads: "Transcript. Score: 2, Evaluation: D, failed this test."

Rimbaud frowned and found that Eris also received a report card, which read: "Score: 1, Evaluation: D, this test is unqualified."

Rimbaud laughed: "A rag doll without a head."

Eris rolled the transcript into a ball and threw it back: "It's only one point higher than me, and the evaluation is D. You can't do well, anyway, you don't pass, because the more words you write, the higher the score."

Rimbaud folded the transcript and stuffed it into his backpack: "I'm only three points away from the perfect score, which is a good result."

——

"Forget it." The puppet master listened to the discussion between the two people on the communicator and looked at Bai Chunian, "Let's find a way to solve our predicament first."

"Back up." Bai Chunian twisted his wrist, took a half step back, took a deep breath, and concentrated his strength to the heart of his fist. A wave of brandy-flavored pheromones instantly excited, his smooth arms varicose blood vessels and muscles swelled, a white lion's front paws transformed from fingertips to forearm to forearm, paused slightly in the air, and charged forward at an extremely fast speed. hit out.

Boom! The gust of wind he brought lifted the hem of the puppet master's trench coat, and the puppet master calculated his strength in his heart.

A feeling of numbness and numbness quickly spread from the fist bone to the entire arm. Bai Chunian's face was in pain.

Bai Chunian held his left hand and gritted his teeth and endured it. The wound began to heal with pain relief. He raised his head and saw that the digital display on the wall began to beat.

"Current punching strength: 6794kg, average punching strength: 3691.5, number of punches: 2."

Nearly seven tons, an amazing blow. The puppet master commented in his heart.

The light showing the numbers turned green, and then a piece of paper was slowly spit out from a small gap on the side of the wall.

The puppet master took the piece of paper: "Well, it's a transcript."

This is a piece of paper with a background pattern that resembles a certificate of merit. It is printed with: "Score: 78, Evaluation: A, pass this test."

The sturdy beating test wall rises slowly.

Bai Chunian glanced at the transcript and was surprised: "I only got 78 points?" He raised his head and kicked the wall: "Come down, I will take the test again."

On the other side of the communicator, Eris suddenly interrupted: "Ow? A perfect score of 100?"

When Lan Bo heard Bai Chunian talking to himself, he silently took out his transcript from his bag and ate it in a ball.

After the impact test wall was raised, a corridor appeared, and the two walked inward for about 30 meters along the corridor.

I thought the test could be finished behind the wall, but unexpectedly, a row of cubes of various materials were neatly arranged in the second room, and the electronic digital display on the wall: crushing force test.

"..." Bai Chunian took a deep breath, stepped forward and knocked on the cubes, including granite, steel and cast iron, and lead.

"Hey..." Bai Chunian sat down on the spot, lifted his sweaty neckline and shivered, holding the report card and fanning the cool air: "I'll take a break."

After a while, Rimbaud's voice suddenly became tense: "randi, randi."

"Fire..." Rimbaud's breathing became rapid: "Fire is chasing from the elevator."

Bai Chunian regained his energy and became vigilant. He glanced back at the way he had come. He quickly walked back along the corridor to the entrance and glanced at it. Sure enough, the flames had engulfed the elevator, and the fiery temperature was blowing towards him. The destruction device did not stop, but as a kind of countdown, it slowly chased, ready to destroy the slow-moving experimental body at any time.

It was a brutal competition, and he felt it right now.

"Break the door for them first." Bai Chunian ran back quickly and sat on the ground. He knew that Lanbo was afraid of fire. Eris' body is made of ceramic, and it doesn't matter if he gets burned, so the puppet master won't be in a hurry.

The puppet master didn't hesitate, and asked softly, "Eris, tell me what's on the door carefully, don't miss it."

Bai Chunian raised his eyes sharply and looked at the puppet master's expression. He didn't look so calm either.

Is the new mechanical core of Eris not fireproof, what non-fireproof material is suitable for the core?

It was too late to think about it, Bai Chunian could only think about Lan Bo's safety first: "Ran Bo, tell me how many grids there are in a row and how many grids in a column."

"Seven." Rimbaud counted carefully, "There are seven squares horizontally and vertically."

Eris replied, "A small number, 175, is written outside the grid."

Rimbaud: "Me too."

Bai Chunian and the puppet master ate at the same time and looked at each other.

"Forty-nine magic squares."

"Fill 1 to 49 in the grid, and the vertical and horizontal diagonals add up to 175."

"The two grids cannot be repeated." Bai Chunian snapped his fingers, "This is simple."

But they don't have a pen and paper, so they can only fill it out by mental arithmetic.

In the communicator, although Rimbaud did not ask for help, his breathing became heavy, and the temperature must have risen to a level that made him painful.
