It didn't take long for Zhang Yuan to find that the jade box had turned into powder, but the aura stored in it was gone.

The jade box could no longer provide spiritual energy, and Zhang Yuan had to use his spiritual power to refine medicine.

Zhang Yuanpan sat on the ground, holding the medicine tripod with both hands, motionless.

It didn't take long for Zhang Yuan's face to be covered with sweat, obviously, the load of this refining medicine was too great.

Finally, the sound of whirring wind sounded around Zhang Yuan, and the medicine tripod also rotated rapidly, if anyone was here, they would find that a tornado seemed to have formed around Zhang Yuan, and Zhang Yuan was right in the center of the tornado.

This time, although Zhang Yuan was very tired, he didn't have the feeling of being squeezed dry like last time.

After another period of time, the rumors stopped, the medicine tripod stopped turning, Zhang Yuan's face looked much better, and the refining of the medicine was finally over.

"Whew!" Zhang Yuan let out a long breath, ready to take out the medicine powder in the medicine pod.

At this moment, Zhang Yuan suddenly felt a feeling of suffocation, and before he had time to think about it, Zhang Yuan held the medicine tripod and quickly moved a few meters sideways.

"Bang!"

The place where Zhang Yuan was sitting before immediately had a large pit more than one meter deep, and black smoke was still rising from the big pit.

"Look for death!" Zhang Yuan didn't have the slightest affection for these killers who wanted to kill him several times.

Zhang Yuan didn't have time to think about it, because another dangerous feeling lingered in his heart.

Zhang Yuan jumped up again, leaving the position where he had been standing.

There was a loud bang, and there was a big crater on the ground again.

"Rocket artillery! You really can afford to look down on me. ”

This time, Zhang Yuan, who was in mid-air, finally discovered the location of the killer and also discovered the killer's weapon.

"Bang!"

Seeing that Zhang Yuan dared to jump into the sky, the killer immediately seized the opportunity and sent out another rocket launcher.

When there was a bang, Zhang Yuan blocked the cannonball with the medicine tripod, his arm was shocked and numb, not to mention, the whole person was knocked out, in a hurry, the medicine tripod in Zhang Yuan's hand was not completely aimed at the cannonball, and after the cannonball hit the edge of the medicine tripod, it actually wiped Zhang Yuan's stomach.

"Huh?" After being rubbed, Zhang Yuan immediately felt abnormal and knew that he was injured.

"Bang!"

The killer is sophisticated and can seize the best time to shoot every time.

"Die!" Zhang Yuan didn't have the slightest pity for the killer who almost killed him, and immediately, Zhang Yuan made a magic decision and quickly flicked a fireball at the killer.

With a snort, Zhang Yuan's fireball turned the killer into ashes.

"Although the cultivators of this world are far less powerful than the cultivation realm, this weapon is much more advanced!" Zhang Yuan couldn't help but sigh.

Zhang Yuan was going to absorb the aura here to heal his wounds, but found that there was no trace of aura here.

"Did I suck it all dry?" Zhang Yuan was a little puzzled, and at the same time dispersed the medicine in the medicine tripod.

"Haha, it's another medicine powder!" Looking at the crystal clear medicine in the bottle, Zhang Yuan was indescribably happy.

"Huh?" Just as Zhang Yuan was about to put the bottle away, Zhang Yuan made an unexpected discovery, and said secretly, "This medicine powder actually contains so much aura!" It's all comparable to the next grade spirit stone! ”

To be honest, Zhang Yuan in the cultivation realm is just a casual cultivator, and his understanding of cultivation knowledge is also very limited, he still thinks that the presence of aura in the Yipin medicine powder is one of the characteristics of the Yipin medicine powder, but he doesn't know that except for the high-grade elixir used for cultivation, the rest of the pills have no aura.

"In this way, there should be a small spiritual vein here, but it was absorbed by Yaosan." Thinking of this, Zhang Yuan was excited.

This powder can not only be used to treat serious injuries, but also to avoid exhaustion in battle.

"Try the medicine first!" Zhang Yuan changed places, took out a small piece of medicine, swallowed it, sat cross-legged on the ground, and began to heal.

Zhang Yuan didn't know that he had been sitting for a full day and a night, and Zhang Yan was very worried. Li Chenghui's family comforted Zhang Yan while sending people to find Zhang Yuan.

However, Zhang Yuan's gains were also very great, not only healed the injuries on his body, but also broke through his cultivation to the middle stage of the second layer of qi refining, and his martial arts cultivation also reached the peak of Ming Jin.

After finishing the work, Zhang Yuan quickly returned to the villa.

"Brother!" When Zhang Yan saw Zhang Yuan, she finally put her mind at ease.

"Yanzi, I've already refined the medicine powder!" Zhang Yuan happily shook the bottle in his hand.

"Brother Yuan, you have been gone for a day and a night, and you don't say hello in advance?"

"Haha, Brother Li, it was my mistake!" Zhang Yuan touched his head embarrassedly.

"How could it be that long? Isn't it a moment's work? Zhang Yuan was a little surprised.

"You guy, where are you fooling around? I don't know when to say! Li Chenghui couldn't help but joke.

"Big brother, there is progress again?" Zhang Yan knew that Xiuzhen had no time, and asked expectantly.

"Hmm!" Zhang Yuan nodded happily.

On the same day, Zhang Yuan used his spiritual power to help Zhang Yan comb his wounds, and then handed the medicine to Zhang Yan and let Zhang Yan refine it by himself.

Just when Zhang Yan was refining the chemical medicine, Li Han came back.

Seeing Zhang Yuan, Li Han actually strongly asked Zhang Yuan to go to their class, and after the people in their school saw the photo of her and Zhang Yuan, they thought that Li Han had gone up by himself, which made Li Han depressed.

Zhang Yuan didn't want to be watched by others, so in desperation, he had to cooperate with Li Han to make a video to prove that he and Li Han were good friends.

Zhang Yan spent a day and a night to heal this time.

However, after the harvest, Zhang Yan also gained a lot, not only curing her leg injury, but also raising her cultivation to the middle stage of the first level of qi refining.

After teaching Zhang Yan the fireball, Zhang Yuan left the Li family and returned to Zhao City, where he wanted to uproot the black boss.

……

In class 051, Zhang Yuan distributed the rearranged materials to everyone.

"Wow, is this information the magic weapon of Zhang Yuan's counterattack?"

"Oh my God, this explanation is too strong, I didn't understand Lenz's law for a long time before, after reading this information, I will understand it once!"

"That's what the law of conservation of electrons is all about!"

"Haha, I can finally solve the genetic reasoning problem!"

In the classroom, after seeing the materials left by Zhang Yuan, there were exclamations.

After that, the teachers of Class 051 were surprised to find that these students were no longer naughty and engaged in learning, although these students still did not listen to their lectures.

"Zhang Yuan, thank you!" The head teacher of class 051 looked at this group of students who were on the precipice, and the corners of his eyes were moist. Because she doesn't know how to lead and speaks straightforwardly, she offends the leader, so she will serve as the head teacher of class 051.

The head teacher of a garbage class like this will not have a good future, but she now sees hope.

Class 051 will no longer be the bottom class.

Zhang Yuan avoided the head teacher's gaze and slipped away from class 051.
