"What is this better than? The Shield of Thorns, the strongest defensive weapon under the artifact, the first head of the Stephen family's personal armor. ”

"Dark Arrow!"

"Big brother, what's the use of your second-order magic?" Many students couldn't help but shake their heads in disappointment after seeing the magic released by Ji Yunfan.

Why bother with this indifferent struggle? The Shield of Thorns, the strongest defensive weapon under the artifact, is invincible at the same level.

What everyone didn't expect was that Ji Yunfan's Dark Arrow did not directly attack Jesean Stephen, but attacked the "oxygen tank".

"Bang!" was another loud popping sound.

Without warning, the flames burst open.

Circle after circle of fiery snakes rolled around the position of the "oxygen tank" and flew wildly. The tumbling heat, the air vibrated under the explosion, and the fluctuations spread in all directions.

Jesean Stephen was once again pushed to the barrier by the powerful impact, and what people didn't expect was that under the protection of the Thorn Shield, the injuries on his body this time were more serious than the last time. Even Ji Yunfan was disgraced by this powerful blast.

"What the hell is going on?" everyone was dumbfounded, staring intently at the two men in the barrier.

Ji Yunfan involuntarily rubbed his ears, and he felt his ears buzzing.

Oh, my God!

What exactly did this little ancestor do?!

Confused, puzzled?

People hadn't recovered from the shield of thorns, and then they were blown up by Ji Yunfan's explosion, and the shock in their hearts couldn't calm down.

Everyone thinks the gods have played a big joke on them, and who can tell me what just happened?

Oxygen can fuel the most common problems on earth, and it exerts its unimaginable power in another world.

"I surrender!" As these three words were shouted, Jesean Stephen collapsed directly to the ground, and endless humiliation filled his heart.

It's just that they haven't been able to calm down until now, and the ending is beyond everyone's imagination.

You must know that a second ago they were still sighing that the shield of thorns was invincible, and ordinary people could not compete with it, who knew that in an instant, Ji Yunfan gave them a big surprise, but how did he do it, is Jesean Stephen just an actor? If you say that other people are actors, it can be said, how can this Stephen family cooperate with Ji Yunfan's performance.

"Mentor Anne, did you open a small stove for Dante, how could Dante be so perverted??" Avril couldn't help but ask.

This time, Princess Avril was completely convinced, and in her eyes, Ji Yunfan was an out-and-out pervert.

She Avril is a dignified princess, with countless resources, learning magic since childhood, Dante, this kid has only been learning magic for a long time, only half a year, today it only took half a year, he reached the fourth order, which is one rank higher than himself, and he has just mastered the third-order magic, this kid not only masters the fourth-order magic, but can even release the second-order magic. During this time, I thought that I had brought Dante closer to this guy a lot, who knew that this guy's cultivation speed was the same as that of a sitting divine beast!

"No, he wasn't in the academy at all during this time, he was all cultivating by himself. Mentor Anne shook her head.

"It's incredible. ”

......

Although the qualifying battle is over, the discussion of Ji Yunfan is indeed not over, and even Vice President Walter Cotton personally called Ji Yunfan into the office, and the two had a long talk.

"Oxygen, you used Oxygen to win against Jesean Stephen in qualifying, can you tell me what happened?"

Ji Yunfan was already surrounded by the tutors of the academy at this moment.

"Absolutely. Ji Yunfan smiled slightly, "Before that, I have a question I want to ask your mentors, how do you say the flame burns, or how does the flame come about?"

"Isn't it because there is a fire-type magic element in this world?"

"Yes and no. ”

"Yes and no?"

"So let me change the question, if you light the torch with fire magic, when the fire magic is removed, the flame will still burn, is this because there is a peace magic element?"

“......”

All the tutors were stunned for a moment, this seemed to be a commonplace phenomenon, and they had never thought about why this was before, but after Ji Yunfan said this, they seemed to be common sense, ignoring something.

"Have you ever thought that if you shut up a living being, that creature will be suffocated to death, why is that?"

Ji Yunfan asked a few questions in a row, and the tutors present who asked him were all stunned, these seemed to be commonplace phenomena, but they never considered why, they just felt in their subconscious that this should have been.

This is the same as the earth where Ji Yunfan originally lived, Newton discovered gravity because of the apple landing. Many times they form a fixed mind, subconsciously feel that it should be like this, and gradually lose the desire to explore the truth, and turn a blind eye.

"This ......"

The instructors present no longer knew how to answer.

"I conducted a series of studies based on these two phenomena, and I found that in a confined space, although the flame can continue to burn for a while, it will not be long before it is extinguished, and if it is in an open area, the flame will continue to burn until the torch burns out. Because of this experiment, I came to a conclusion......"

"What conclusion?"

"There is a special element in the air, this element is different from the so-called magic element, it can not only support the burning of flames, but also support the breath of living beings to survive!" Ji Yunfan said lightly.

"What?!" The mentors present were taken aback by Ji Yunfan's remarks, their first thought was that Ji Yunfan was talking nonsense, but they felt that what Ji Yunfan said was true.

"So I conducted a series of researches, and finally extracted a new element in the air that was different from the magical element, and I named this element oxygen, which can make the body and mind happy when inhaled, and living beings cannot survive in the air where oxygen is completely extracted, and flames cannot burn in this air. Ji Yunfan said lightly.

"What?!There is such a magical element in this world, we didn't even know about it all along?!" Even the two vice presidents of the academy were dumbfounded at the moment.
