At this time, the area where Xiang Chen was located was the legendary Ten Thousand Demon Pagoda on the campus of Nanda University.

Looking at the small black tower in front of him, which was only three stories high, Xiang Chen couldn't help but be a little speechless, he thought that this so-called Ten Thousand Demon Tower would be a more imposing building, but he didn't expect it to be so frustrated.

As he walked into the area where the Ten Thousand Demon Pagoda was located, the number of students coming and going decreased sharply, and at the same time, the immature faces of the new students were basically gone.

Walking into the door of the Ten Thousand Demon Pagoda, a quaint atmosphere came to the face, and the decoration inside was incompatible with the current technological era, and there was an ancient feeling.

The only thing that has to do with technology may be the five elevators in the middle of the building.

At the same time, the moment Xiang Chen stepped into the Ten Thousand Demon Tower, his bracelet rang, and Xiang Chen clicked on it, it was a system email from the Academic Affairs Office.

"Student Xiang Chen, you are now stepping into the important place of our school, the Ten Thousand Demon Tower, please abide by the confidentiality treaty, and do not spread what you have seen and heard in the Ten Thousand Demon Tower."

"Ten Thousand Demon Pagoda Cultivation Rules: Ten Thousand Demon Pagoda is divided into 16 floors, of which 3 floors above ground are the tutor's rest area stationed here, students are prohibited from entering without permission, and the 13 underground floors are open to students.

The main function of the Ten Thousand Demon Pagoda is to greatly increase the cultivation speed of true qi and increase the growth of qi and blood.

Xiang Chen suddenly realized that the so-called Ten Thousand Demon Towers were not above-ground buildings in the general sense, but towers that were pierced into the ground in reverse!

As for the large number of words in its role, it made his eyes shine.

"Among them, the 13 underground floors are divided into five and 5 levels, with floors 1-3 being first-level cultivation grounds, and floors 4-6 being second-level cultivation grounds...... The 10th-12th floors are the fourth-level cultivation grounds, and the 13th floors are the fifth-level cultivation grounds, and there is no difference between the cultivation sites of the same level. Each level has a separate training room, and students can choose the appropriate level to find an unmanned training room to practice. ”

"Credit rules: Level 1 cultivation ground, 40 credits per hour, 80 credits per hour for Level 2 cultivation ground, 160 credits per hour for Level 3 cultivation ground, and 320 credits per hour for Level 4 cultivation ground. The fifth-level cultivation land cannot be entered by consuming credits, and can only enter the top ten of the overall list of the martial arts academy and obtain the corresponding quota. ”

Xiang Chen was secretly speechless, no wonder they all said that the Ten Thousand Demon Pagoda was a gold elimination cave, which was also too dark.

"Ranking rules: In each grade list, 21-50 students can get 40 credits of free cultivation quota per month, 11-20 students can get 80 credits of free credits, 6-10 students can get 160 credits of free credits, 2-5 students can get 320 credits of free credits, 1st place can get 640 credits of free credits, and unused free credits can be stacked to the next month.

Note: It is not recommended for new students to challenge the cultivation ground of level 2 and above, and the cultivation of the Ten Thousand Demon Pagoda is not risk-free.

The 6th-10th place in the overall list can get a free 1-hour cultivation quota for the 5th level cultivation ground every month, the 4th and 5th places can get 2 hours, the 3rd place can get 5 hours, the 2nd place can get 10 hours, and the 1st place can get 20 hours. The difficulty of the fifth-level cultivation ground is far greater than that of the fourth-level, so please do what you can. ”

Reading all the emails in one go, Xiang Chen also has a general understanding of the Ten Thousand Demon Tower, this rule is generally very good for freshmen, after all, for the seniors, maybe the rewards of the grade list are not very important, but for the freshmen, it is tantamount to sending charcoal in the snow.

Counting the 2nd grade in September and the 3rd grade in October, Xiang Chen has accumulated a total of 640 credits of free credits, that is, he can choose to cultivate for 16 hours in the first-level cultivation ground or 8 hours in the second-level cultivation ground.

Xiang Chen decided to choose a first-level cultivation place to try first, the system's prompts were not unreasonable, blindly challenging the high difficulty was just increasing the risk.

He entered the elevator and pressed the bottom 1 floor.

When the elevator door opened, Xiang Chen almost didn't spit out.

A fishy smell penetrated his nostrils.

Resisting the urge to vomit, Xiang Chen looked at the underground floor.

The entire basement floor is a circular corridor design, and the corridor is full of independent rooms, the room shows a green light to indicate that no one is occupied, and a red light means that it is occupied.

Curious, he took the elevator down a few floors to take a look, Xiang Chen found that the more down, the smaller the area of the floor, the fewer the number of rooms, on the contrary, the fishy smell of geometric multiples, but the students in the past seemed to be familiar with this.

As for the bottom 15th layer of item dust, there is no permission, and he can't get in.

Returning to the first-level cultivation ground, Xiang Chen swept open an idle cultivation room with a martial arts bracelet, and at the same time, the timer device in the cultivation room began to time.

The facilities in the cultivation room are very simple, a stove-like device connected to the ground, an iron bed, and no other facilities.

Xiang Chen sat cross-legged on the iron bed, and saw an electric switch-type switch on the wall, which was in a closed state at this time, and there was the words "Please turn on the switch when you start practicing" next to the light.

Xiang Chen pulled the switch, and the stove on the ground made a slight humming sound, and then a fishy smell mixed with the aroma of medicinal herbs emanated from it, but the smell was not very bad.

The smell of herbs wafted to Xiang Chen's nose, and after just smelling it, Xiang Chen's complexion changed.

He felt a fire burning in his lower abdomen, and at the same time, the temperature of his body rose rapidly, and soon exceeded the normal body temperature, his face turned red, and his clothes were soon wet with sweat.

Xiang Chen's heart beat violently, and a large amount of fresh blood was constantly pumped out, flowing to all parts of his body, and at the same time, the power of his qi and blood suddenly rose a little.

Xiang Chen's face was very solemn, the power of qi and blood is by no means the higher the better, the power of qi and blood can be quickly raised, but it is impossible for the body function to improve so much at once, if the body can't keep up, and the qi and blood are too high, soon his body will be like a balloon that has been blown up, exploding and dying.

Xiang Chen hurriedly set up the cultivation posture of the five hearts to the sky, and operated the Eight Extremes, such a pure power of qi and blood, the best way is to use it for cultivation.

Xiang Chen didn't blindly convert his qi and blood into true qi, which would cause his true qi to increase too quickly and become vain, destroying his foundation.

He frantically compressed his true qi and expelled the residue of qi and blood out of his body with his breathing, even so, Xiang Chen clearly felt that his cultivation speed at this time was far beyond that outside the tower.

Time passed rapidly in the process of cultivation, and after nearly two hours, Xiang Chen suddenly opened his eyes, and a light like a substance of true qi shot out from his eyes, more than a meter long.

Xiang Chen shook his hands, his face full of disbelief.

In this short two-hour cultivation process, not only did his qi and blood rise a bit, but even his true qi visibly increased a lot, and the effect was comparable to practicing outside for several days.

The distance from the dantian is completely full, and it is close at hand!

…………

Walking out of the Ten Thousand Demon Tower, Xiang Chen still couldn't help but look back at the black pyramid-shaped building.

"What a magical Ten Thousand Demon Tower." Xiang Chen sighed, and at the same time secretly wondered in his heart, what kind of principle this Ten Thousand Demon Pagoda was, but no matter how he looked up on the school's forum, he couldn't find any posts about the principle of the Ten Thousand Demon Tower.

Xiang Chen had no choice but to give up.

At the same time, he finally understood why the students who had seen them in the past showed such tired expressions.

This exhaustion is not physical exhaustion, but a feeling of swelling and pain from the meridians. The Demon Refining Tower is like having the effect of a turbocharger, increasing the cultivation speed of the True Qi several times, and this brings a tingling sensation after the excess True Qi is pressed through the meridians.

Feeling this tingling sensation, Xiang Chen knew that he would not be suitable to come to this Ten Thousand Demon Pagoda to cultivate for at least one day.

In addition to the tingling sensation in the meridians, another problem is the excessive exuberance of qi and blood and some physical fitness that does not match. Generally speaking, with the continuous tempering of the body and the cultivation of true qi, the qi and blood will also increase at a corresponding rate, but after the cultivation of the Ten Thousand Demon Tower, this balance has obviously been broken.

"How do you maintain this balance?" Xiang Chen pondered for a long time, and suddenly he had an idea, "Ten Thousand Demon Tower, gravity room, yes, these two places are simply complementary golden partners!" ”

Xiang Chen dragged his stinging body to the gravity room located in the special cultivation room of the Martial Academy.

At this time, there were already many martial artists practicing in the gravity room, and Xiang Chen went straight into the 2x gravity zone.

The so-called 2 times gravity is by no means as simple as bearing 2 times the weight, otherwise let alone 2 times, 20 times is not a problem for Xiang Chen at this time.

The real burden of high gravity is the internal organs of the human body, in the double gravity zone, Xiang Chen's internal organs are all operating under weight, and every beating of the heart is extremely heavy and slow.

The 2x gravity zone is extremely large, and in the far corner, Xiang Chen saw Wang Shilei who was practicing cross-legged, and secretly said that this guy is really hard enough to practice.

How did he know that Wang Shilei was stimulated by him in the gymnasium that day.

When Xiang Chen looked at him, Wang Shilei felt something, and opened a pair of tiger eyes, at this time he was sweating profusely, and the muscles of his whole body were shaking unconsciously, which was a sign of hard training to a certain extent.

After glancing at Xiang Chen, he looked away and closed his eyes again, bearing the baptism brought by high gravity to his whole body.
