"I really convinced him..." Ling Xingye held the package and couldn't help complaining.

Then, Ling Xingye walked directly into the opposite research institute—except for the sprites, he still had other equipment that needed to be replenished.

And in order to make a new puppet, he needs to borrow the 3D printer here.

Finding a spare laboratory, Ling Xingye opened the spider's package by the way.

There is only a stack of A4 printing paper inside, and nothing else.

"Is this what he said could improve his strength?" Ling Xingye muttered.

A few days ago, when he contacted the spider email, the other party proposed to provide a "strengthening" plan.

I thought that the spider was also a senior "Silver" puppet master, and he should be able to teach himself some "Silver spells" similar to removing curses, but he got a document.

"Could it be some kind of secret book? But I have never heard that magic books can be printed with a printer."

Ling Xingye flipped through it patiently, and found that it turned out to be a paper.

"So that's the case... no wonder it can improve my strength." After reading the paper, Ling Xingye suddenly realized.

This paper describes the structure, properties and fabrication methods of a certain organic polymer.

Although the whole text is full of professional-level formulas and physical and chemical knowledge, it can be easily understood.

Because he has read a lot of similar papers, and actually participated in the publication of a paper.

The subject of that thesis was one of Ling Xingye's current combat equipment—spray quick-setting silk thread.

At this time, seeing the paper provided by the spider, Ling Xingye had a strong sense of déjà vu.

Because this is the article he personally participated in writing!

However, a part of the content was added at the end of the thesis—the spider gave a brand new formula, and as long as a slight modification was made on the original basis, a silk thread with better performance could be obtained.

It was even comparable to the silk of the precious "three thousand year spider" in Ling Xingye's hands.

This undoubtedly solved Ling Xingye's urgent need. With the improvement of his strength, the "Phase Fulcrum" has been confirmed to be upgraded to level 4, and the original "flying blade" and spray quick-setting silk thread are no longer usable.

There are raw materials and instruments in the laboratory, and Ling Xingye quickly prepared new silk threads.

After experimenting, it really can withstand his more powerful quick operation now.

"Unfortunately, the effective time is still less than 700 seconds, otherwise it is simply a miracle material."

Ling Xingye sighed, and improved all the sprays in the bag to the latest version.

After doing this, I went to the next door laboratory to print out the parts needed to make the puppet.

Ling Xingye didn't leave the institute until one o'clock in the afternoon.

"Next... what should I do?" Ling Xingye looked up at the dazzling sunlight outside, "Well, take a break today, so I won't go to the show."

Thinking of this, Ling Xingye walked back, took out his mobile phone, and called Hitomi Shiranui.

"It's so rare that Xingye actually thought of taking a rest!" Hitomi Shiranui said in surprise.

"Is it that exaggerated? I'm human too, and there's always time to rest." Ling Xingye said helplessly, "Anyway, are you free now?"

"Of course!" Hitomi Shiranui immediately replied, "It's rare that Xingye invites you, let's go out and play!"

"That's right, there is less than a week left in the summer vacation, it's time to enjoy the vacation."

After making an appointment, Ling Xingye bought some bread nearby for lunch, and then rushed back excitedly.

He and Hitomi Shiranui agreed to meet at the apartment.

Ling Xingye thought that he should really relax and adjust his state.

This summer vacation was so abnormal that Ling Xingye almost forgot the fact that he was still a high school student.

School will start in a few days! You must break free from the daily routine of fighting and killing recently.

Ling Xingye returned to the apartment by car, and began to check the information of the sixth school district in the car.

It's home to Academy City's - probably the world's - best amusement park.

And it's open 24 hours a day.

The ticket price is naturally expensive, but Ling Xingye booked two tickets without hesitation.

…

"Then, what's going on here?"

——At the door of his apartment, Ling Xingye's keen ears heard the noise in the house, and an ominous premonition suddenly rose in his heart.

As soon as I opened the door, I saw that my house was full of people!

Of course, this is an exaggeration. However, as long as there are more than three people in a single apartment that is not spacious, it will be very crowded.

They are all familiar guys—except for Hitomi Shiranui, Misaka Mikoto and Misaka 10001, and the relatively unfamiliar girl Harukami Jinyi.

For a moment, Ling Xingye thought he had gone wrong—maybe this is the girls' dormitory?

But the various puppets and dolls all over the house still brought him back to reality.

Seeing the owner of the house come back suddenly, the children all over the room suddenly fell silent, and hurriedly put the doll back to its original place.

Shiranui Hitomi looked at Ling Xingye who was stunned at the door with apologetic eyes.

"...So, what's going on here?" Ling Xingye asked again with a blank expression.

Misaka 10001 raised his hand first: "Misaka is taking advantage of free time to go home and visit. My sister and the others came here without authorization. Misaka is the first to file a complaint."

"I heard that you are not easily allowed to go out, so I came here to accompany you!" Misaka Mikoto retorted immediately, "Also, what the **** is going home to visit! This is Xingye's apartment!"

"Ah, it's so rare that someone still remembers that this is my house..." Ling Xingye said indifferently.

"Because Misaka lived here before, this is Misaka's first residence outside of research facilities. So Misaka thinks this is Misaka's home. Misaka explained her reasons."

"It's really abnormal!" Shirai Heizi jumped out, "You man, what did you do to my sister!"

"Hey..." Ling Xingye tentatively accepted the fact, and pushed away the guy who jumped in front of him, "Is your discipline committee member so idle?"

He went in, looked around, and saw that the room was a mess—although it was a mess.

It can be seen that when he was planning to go to the amusement park, these middle school students seemed to regard their room as an amusement park...

During the day ~lightnovelpub.net~ the dolls and puppets in Lingxing Night House are not scary at all.

—Should let these girls come over late at night to take a look...

"I'm sorry, I'm sorry," Saten Ruiko folded her hands above her head and bowed at ninety degrees. "We just want to see the performance that we missed the day before yesterday."

Chuharu Riya bowed together: "I'm very sorry."

Chunshang Jinyi hugged a doll bear, and sat on the ground blankly, but did not respond.

"Okay, let's drink tea first." Hitomi Shiranui brought out the brewed black tea and snacks from the kitchen, and took the initiative to entertain the guests.

After temporarily calming down the situation, Ling Xingye followed Hitomi Shiranui into the kitchen.

"I'm sorry, Xingye," Shiranui Hitomi smiled wryly, "I didn't expect it to become like this..."

"So, what happened?" Ling Xingye sighed for the third time.
