After the last time the toilet was asked for paper, this time Tao Li had an extra heart, a total of two squatting pits, Tao Li after some inspection, found that there was no one, so he walked into one of the squatting pits by the inside and locked the door.

"The bathroom near the principal's office is high-end, and there is not even a urinal!" Tao Li muttered as he locked the door.

After staying in the principal's office for so long, Tao Li had long wanted to release himself, but after entering the bathroom, he found that there were no urinals except for two squatting pits.

The man's self-esteem makes Tao Li unable to tolerate squatting and booing, especially squatting and booing when he is not pulling, it is simply a humiliation under the crotch!

I'd rather pee in my pants standing than squat and sprinkle in a squatting pit!

Tao Li is such a principled person!

Speaking of this, Tao Li couldn't help but think of the black history in kindergarten, wearing a skirt and braids, he was led into the women's toilet as a girl......

"Forget it, let's hold it for a while!" Tao Li took a sharp breath, for him who had already practiced the eighth layer of the Dafa of Holding Gong, this was not a matter at all!

Hold back and shoot freely, this is the embodiment of a man's true ability!

"What the hell is the system mall?" asked Tao Li impatiently after sitting down.

"As an extension of the system's functions, the mall was set up to better serve the host!" the system quickly replied, but such an answer seemed idiotic to Tao Li.

"Can you be more detailed!" Tao Li was helpless, so he could only ask again.

Such a system is too unintelligent, as if he can only answer the question in detail if he concretizes the question, otherwise, it will be like a bead on the abacus, dial it before moving, very stupid!

"All the things that the system has, can be exchanged in the mall through points, mall items, according to the category is divided into technology and props, technical goods according to A, B, C, S, X grades, the required exchange points increase step by step, and the props commodity registration system is not obvious, but according to the power of the function, its price will be graded!"

While explaining, the system showed the interface of the system mall to Tao Li, although the system's answer still did not meet Tao Li's requirements, but Tao Li already roughly understood what the situation of this mall was.

Under Tao Li's operation, a large screen similar to a holographic projection soon appeared around Tao Li's body, and this should be the main interface of the mall. The main interface is very simple, there are no fancy things, just simply display the two options of "technical" and "prop".

Tao Li thought about it, and then clicked the "Technology" button, without any delay, the interface in front of Tao Li changed instantly, densely covered with various teaching techniques.

Board book technology!

Chalk word technique!

Marking technology!

Question technique!

…………

There are about more than 100 in total, Tao Li randomly clicked into one, and found that each technology is different according to the level, and the points required to exchange are also very different, just take the "multimedia courseware production technology" obtained by Tao Li at the beginning, the lowest level A only needs 10 points to successfully obtain, but then to the B level, the required points suddenly reached 100 points!

The S-level technology obtained by Tao Li is as high as 1,000 points! Not to mention the highest X-level, the high exchange price of 5,000 points is enough to discourage Tao Li!

Of course, not every A-level technology is so cheap, in the last row of the interface in the last option called "Teaching System Design Technology", just the A-level technology, it takes 20,000 points to redeem!

In the other "Turning Stones into Gold Technology", the most basic A-level technology also requires 5000 points to be redeemed! In the introduction of this technology, Tao Li also understands why this technology is called "Turning Stones into Gold" and why it is so expensive!

In the introduction of this technology, it is written that "this technology can help the host guide any student with corresponding talent to obtain national and even Nobel Prize-level scientific research results!"

Although there are only a few simple words, Tao Li is clear that if this technology can be sold at a clear price in reality, it is definitely the kind that has no price and is the kind that grabs the head!

With this technology, those mathematical and physical problems that have puzzled mankind for decades or even hundreds of years, such as the crown Goldbach conjecture in number theory, and Einstein's unified field theory of the universe, which he failed to solve in his lifetime, may be able to solve them easily!

But if you want to solve such a "stone into gold", I am afraid that at least X-level technology will be required, Tao Li looked at the price of 100,000 points, and then looked at the few system points he had left, so he had to temporarily dispel this idea.

You still have to work hard to earn points!

In addition to the lack of points, Tao Li was unable to obtain these technologies, Tao Li also found that some of the technologies in this are highlighted, and some are dim, such as the teaching system design technology, although you can click in to view, but if Tao Li wants to redeem, there will be a few prompt texts such as "Please get computer programming technology first"!

It can be seen that the system is still very strict in terms of technology exchange, if you want to obtain one of the technologies, you must have the corresponding other technologies as support, just like the board book technology obtained before Tao Li, if Tao Li wants to exchange in the mall, you also need to obtain chalk word technology, typesetting technology, drawing technology and other related technologies!

This arrangement also reflects the gradual cultivation of a person, rather than pulling out the seedlings to help them grow!

After reluctantly exiting the current interface, Tao Li clicked into the screen of the props class to check, and I have to say that the things here also make Tao Li feel crazy!

Super Particle Collider!

Black Hole Simulator!

Tripetone supercomputer!

Universal Mathematical Reasoner!

…………

These props, supplemented by the corresponding technology, are simply an incubator for the Nobel Prize!

After reluctantly forcibly exiting the mall interface, Tao Li was full of ambition, and the unlocking of the mall made him see thousands of possibilities!

However, this kind of thing still has to be played by RMB players!

Just like Ma Huateng said, there is no game that can't be solved by charging money, if there is, it means that you don't have enough money!

After squatting for more than ten minutes in a row, Tao Li's legs also felt numb, Tao Li stood up and slowed down. was about to open the door and walk out, but a voice came that almost made him hold back for a long time.

It's not that I encountered a dead pervert who borrowed paper again, but the voice Tao Li heard, it was really a woman's voice!!

Tao Li subconsciously looked at the paper basket at his feet, and sure enough, he saw something that he shouldn't see, revealing a hint of red......
