A-level items are generally top-notch when they reach A10 level, and there are also A11, A12 or above, but most of them are just gimmicks from merchants to increase prices.

In terms of utility, it is better to be of B-level B. Du Bixing found a B1-level Beast Bone Marrow Essence on the Hunter Alliance Mall, which costs 990,000 yuan, which can greatly improve bone strength.

For this reason, Du Bixing not only spent his savings, but also borrowed some money from his roommate.

In the gravity practice room, Du Bixing brought the essence of the bone marrow of a strange beast and prepared to carry out the final practice of iron bones here.

There is a ten times the gravity field in the practice room, and Du Bixing first warms up the starry sky guidance technique as usual.

The early bone discomfort period has passed, and now ten times the gravity is no longer a problem for Du Bixing.

After warming up, Du Bixing began to practice the Force. He took the essence of the bone marrow of a strange beast. Because this thing contains too much energy, it seemed like swallowing hot magma into the esophagus. Du Bixing felt that it was about to spit out the fire in his mouth!

Using his exercises, he decomposes these energy consumption into the most basic cosmic force and absorbs it by himself. Some of the materials that are beneficial to the bones are also activated by the force and transported to the bones for absorption and strengthening.

His bones began to undergo a final transformation. Just like those strange beasts with exoskeletons, the bones grew from a thin film to a hard weapon!

And the most amazing thing is that this is not to really turn the bones into metal, similar to transforming humans. Instead, it strengthens the strength and toughness of cells, which can either become a hard skeleton or flexible cartilage.

With the strengthening of the bones, Du Bixing's body's evolution has also increased. Now it has reached more than 90% of the intermediate original warriors!

"Master, the evolution speed has slowed down and the pressure needs to be increased. It will be eleven times the gravity!" The ball woman was always observing his physical condition.

Du Bixing acquiescedly, the gravity of the gravity field was increased to eleven times! In just ten minutes, the ball girl increased to twelve times!

Every time, the ball girl doubles the gravity. Du Bixing no longer has the energy to consider how many times the gravity it is. He can only concentrate on practicing the martial arts, allowing the Force to penetrate every cell and provide them with evolutionary energy.

I don’t know how long it took, but Du Bixing only felt a sudden relaxation in his body, as if a hill carrying him was suddenly removed by someone. The bones were completely closed and stopped growing.

The voice of the ball girl rang in his ears: "Congratulations to Master, you have completed the iron bone practice and successfully advanced to the advanced original warrior!"

"Success!" Du Bixing stood up, feeling extremely happy all over his body. The "weakness" and "sour and itchy" of his bones that had been nearly two months old finally disappeared.

"Why is it so easy? Is gravity shut down?" Du Bixing asked.

As soon as he finished asking, he saw the virtual panel in the room showing that the current gravity increase was fifteen times!

"What? It's fifteen times, why am I not tired at all?" Du Bixing said in surprise.

The ball girl said: "Because you are already a high-level warrior! And you also have iron bones, and this pressure can be fully withstanded!"

Du Bixing was still surprised. His mentor Yan Jingrong said before that a high-level warrior directly enters the ten times gravity practice. After two months of training, he should be able to support fifteen times gravity, but it is absolutely impossible to be as relaxed as him.

In other words, Du Bixing can withstand higher gravity and will not feel struggling!

Moreover, this is just the ability to withstand. After reaching the advanced original warrior, Du Bixing's physical fitness and force level have been improved.

...

Soon, it was the day for the first freshman assessment of Zhenwu Academy. All students in the college conducted gravity field adaptation training at the beginning. Therefore, this assessment is also about gravity field.

The students in the class have arrived. Yesterday, Yan Jingrong informed them that the assessment will be held today.

Du Bixing hasn't met these "classmates" much for two months, by the way, there is also a tutor.

Before Yan Jingrong came, the students were having a lot of chatting.

"I'm going to have an assessment today, so nervous! I can only adapt to six times of gravity now!"

"Don't worry. You are an intermediate original warrior, and you should pass the exam six times."

"Tian Hui, how many times can you do?" someone asked.

Tian Hui said proudly: "Ten times!"

"Ten times!" the students said in surprise, "You are the intermediate original warrior, you are already ten times! This assessment is almost certain, no wonder the mentor focuses on cultivating you!"

Tian Hui pretended to be modest and said: "Overall, Lei Ye is the strongest in our class. He is now a high-level original warrior and has been able to practice in the fifteen times gravity field for a whole day!"

"Fifteen times!" The students took a deep breath and looked at Lei Ye, "This multiple is normal to practice, and his physical fitness is too strong!"

Lei Ye was relatively calm and said, "On average, it's not the limit yet. I just hope to get a ranking this time and strive to join the Taizhou Club!"

"Taizhou Society, big guy, can you join the Taizhou Society?" several students asked hurriedly.

"Not sure. But I heard that those who perform well among the freshmen can be invited by the Taizhou Society."

"It's amazing. We only want to pass the exam. The geniuses are already thinking about how to enter the Taizhou Club!" The students were moved. They have begun to realize that even in the Taizhou University, which has many geniuses, the gap between people is still so big!

"That presumptuous question, how many colleges are needed to join the Taizhou Society?" Du Bixing interrupted.

He is very interested in Taizhou. What is an organization that brings together geniuses from all generations of this school?

When the other students heard Du Bixing's words, they fell silent at the same time, all looking at him with strange eyes.

A second later, Tian Hui laughed and said, "You ask this? Do you want to join the Taizhou Club? Stop being funny!"

Others also laughed, "You should care about how many times the gravity can pass!"

"I think I should be worried about not being dropped out of school! If the credits reach less than minus ten, I will be dismissed from withdrawing!"

For two months, they almost never saw Du Bixing while practicing in the gravity room. So everyone agreed that this classmate should have a poor talent and could not endure hardship, so he gave up on himself.

Before they knew it, they had already excluded Du Bixing from the collective.

Even the mentor Yan Jingrong gave up after several random checks, after not finding out that Du Bixing was practicing in the gravity room. He even felt that if Du Bixing's grades were assessed this time, it was necessary to ask the school to persuade the student to withdraw so as not to affect his tutor's evaluation.

Du Bixing said calmly: "What are you excited about? I'm asking Lei Ye."

He looked at Lei Ye, but Lei Ye didn't laugh at him. He was too lazy to joke about it. In fact, in Lei Ye's mind, the people around him were also optional.

"About the top ten." Lei Ye still answered.

"Thank you." Du Bixing nodded.

"Are you planning to get tenth place in the academy?" Tian Hui teased deliberately, "Come on, I'm optimistic about you. It's not OK to count, and there's still a countdown!"

Everyone laughed, and Du Bixing saw Tian Hui's expression, as if he had seen Zhang Zhigao in high school. He snorted coldly: "Sensationalism."
Chapter completed!
