The office was very quiet, the pin drop could be heard, and the vice principal was just watching something at the desk, and didn't pay attention to Ji Dong and the others.

"Knock knock~~!"

"Come in!"

"Hello Headmaster!"

"Hmm!"

The person who came was Song Liangren, Lin Lang and Lin Tao.

"It's all here! Then I will start to give you the rewards for the year-end assessment of the freshmen. The vice principal said.

As soon as they heard the reward, everyone's spirits were shocked, they were not keen on the so-called money or anything like that, but they were curious about the Nine Heavy Power Tower, which was said to be a cheat for cultivating skills.

"In this year-end assessment of freshmen, each of the top ten will have a [Bronze Guarantee Card]."

"Then it's the cultivation time of the Gravity Tower."

"First place, Ji Dong, the cultivation time of the gravity tower is 100 hours."

"Second place, Song Liangren, the cultivation time of the gravity tower is 90 hours."

"Third place, Tang Mumu, the cultivation time of the gravity tower is 80 hours."

"Fourth place, Wang Lei, the cultivation time of the gravity tower is 70 hours."

"Fifth place, Lin Lang, the cultivation time of the gravity tower is 60 hours."

"Sixth place, Ou Shuisu, the cultivation time of the gravity tower is 50 hours."

"Seventh place, Su Man, the cultivation time of the gravity tower is 40 hours."

"Eighth place, Lin Tao, the cultivation time of the gravity tower is 30 hours."

"Ninth place, Wang Hao, the cultivation time of the gravity tower is 20 hours."

"Tenth place, Zhang Ze, the cultivation time of the gravity tower is 10 hours."

"The gravity tower is a very scarce resource, and there are only two in the entire Tang Kingdom, so the cultivation time is calculated according to the hour, and it must be used reasonably."

Out of the office, Xue Mingyue led Ji Dong and the others straight to the Nine Strength Tower.

The Nine-Weight Tower, thirty meters high, is a hexagonal tower, and its exterior looks like it is made of black metal, rising straight and like a natural one.

Enter the gravity tower, which is brightly lit and technological, and on the side of the entrance, there is an elevator.

"Nine Heavy Force Tower, the first heavy force is up to ten times, suitable for the Black Iron stage, there are a total of nine rooms, we need to go to the second one." After speaking, Xue Mingyue took Ji Dong and the others into the elevator.

"Huh! Teacher, why isn't there a ninth floor? It's obviously a nine-fold tower! Zhang Ze pressed the second floor of the elevator, saw that the highest was only eight floors, and asked curiously.

"The ninth replay of the energy source of this gravity tower seems to be the beast crystal of a king-level fierce beast, and I don't know very well." Blood Mingyue said.

"King-level beast crystal?" Everyone was suddenly shocked, the beast crystal, it's still a king-level, if you can get it, then hehe.

"Ding~!"

The elevator doors open.

A corridor about one and a half meters wide, very narrow, on both sides of the corridor are rooms, there are only eight rooms, the space between the doors is very small, and the space inside is not very large.

"This is the second layer of the gravity tower, with a gravity of up to twenty times, which is suitable for bronze rank cultivation." Blood Mingyue said.

"Teacher, how can we get in, there is no gatekeeper here, and the school has not issued us any tokens or anything like that." Zhang Ze stood in front of the door, looking left and right.

"Stupid, there is someone in front of you, of course you can't get in, the school has already entered your information into the information database of the gravity tower, you just need to put your hand on the door, the door will automatically open, someone's room will be lit up with a red light, and no one's room will be lit with a green light."

'Green light! Ji Dong saw that the room next to him was a green light, so he raised his hand and put it up.

The door opens silently and automatically.

"Teacher, I'll try it first." Ji Dong stepped in.

"Alas~! I haven't..." Blood Mingyue was just about to stop it, but Ji Dong had already disappeared.

"Teacher, what's wrong?" Tang Mumu asked.

"I haven't told you how to use it yet! This little slippery head is too anxious. ”

in the room.

Ji Dong looked around, and there was nothing bare.

"What about gravity? Why don't you feel it? Ji Dong looked around suspiciously, "Huh? What is that? ”

Ji Dong walked to the side of the door, where there were four buttons.

Begin! Stop it! Aggravate! Lose weight!

"Small!" Ji Dong smiled confidently, reached out and pressed the green start button.

"Puff~!"

Ji Dong just pressed the start button, and suddenly his eyes went black, and the whole person fell directly to the ground, unable to move.

"Poof! Poof! ~~~~！ ”

The sound of the heartbeat was as loud as a drum, the sound of blood flowing was like a stream, and everything was so clearly audible.

"MMP, it's too big." Ji Dong thought of it, fortunately the door was closed, otherwise, he would not have been laughed to death by Xue Mingyue and the others.

It stands to reason that entering the gravity room should not be like this, but in the gravity room that Ji Dong entered, the gravity was adjusted to a maximum of twenty times at this time, and it was the first time that Ji Dong entered the gravity room, without any defense, and it was normal to be crushed.

"Arthur fits!" Ji Dong entered the state of the combined body of the heroic soul Arthur, and suddenly, his body strength increased by forty percent, and he staggered to his feet.

"I minus, I minus, I minus ······"

"Whew~!"

It was reduced to the lowest 11 times the gravity, and Ji Dong breathed a sigh of relief.

After acclimatizing for a while, Ji Dong began to slowly increase gravity, and with each double, Ji Dong adapted for a while, and finally the gravity multiple stopped at 15 times.

"Holy, is my body so weak? It can only withstand 15 times the gravity, which is so far from 20 times? "Ji Dong feels incredible, you know, he is now a bronze ninth rank, only two small ranks away from the silver rank, according to what Blood Mingyue said, the black iron is ten times the gravity, the bronze is twenty times the gravity, then the silver is not thirty times the gravity.

"I haven't even reached the average, what a weak chicken!" After Ji Dong finished complaining, he immediately began to cultivate.

Exercise! Exercise! Exercise!

Under the pressure of the limit, it is extremely difficult to complete a set of [Basic Footwork], and it is also a luxury to complete a set of [Basic Knife Technique].

Ji Dong sweated like rain, exhausted, gritted his teeth and persevered.

In a fifteen times gravity environment, Kito easily reached the limit.

Whenever his physical strength was completely exhausted, Ji Dong lay motionless on the ground like a salted fish, and after recovering his strength, he would devote himself to cultivation again.

Every step needs to grit your teeth and persevere, every move needs to use the strength to eat, and the sweat has already soaked the ground.

"Whew~!"

"Bang~!"

Finally, after three hours and fifteen minutes of cultivation, Ji Dong passed out due to excessive consumption of mental power, and his anger was like a gossamer, as if he had served eight young women in a row.

PS: As the saying goes, thirty is like a wolf, forty is like a tiger, and the tiger and wolf are powerful, so I ask you if you are afraid, if you can stand firm until dawn, if you can, don't vote, if you can't, please be conscious, haha.
