In a lounge in the college's office building, Zheng Jian sat intently in his seat.

The wanderer stood on the steps ahead, with a movable blackboard behind him.

"If you want to learn to develop electromagnetic forces, you must first understand electromagnetic forces!" The wanderer shouted as he wrote something on the blackboard.

"So Garfield, tell me what electromagnetic force is?" After writing the formula, Wandering looked at Zheng Jian.

"Well... Well, the electromagnetic force is one of the four fundamental forces. Zheng Jian exclaimed while trying to recall the knowledge of his own evil supplement, "Electromagnetic force is the general term for the force exerted by electric charges and currents in electromagnetic fields......

"Yes, you already have a preliminary understanding of electromagnetic forces, so let's get back to the topic, how do we develop electromagnetic forces?" Wandering glanced at Zheng Jian appreciatively, and then asked, "Do you have any ideas of your own?" ”

"Electromagnetic cannon!" Zheng Jian didn't think about it, and blurted out directly.

"What else?" Wanderer asked.

"Manipulate the magnetic field!" Zheng Jian said a little unconfidently.

"Anything else?" The wanderer continued.

Zheng Jian shook his head, "I don't know!" ”

"It seems that we need to start learning from the basics...... wandering earnestly and in detail, "it is shown in Coulomb's law and ampère experiments that an electric charge is subjected to the Coulomb force in an electric field; The current is subjected to ampere force ...... in a magnetic field"

Zheng Jian: (⊙x⊙; )

"Therefore, as mentioned above, under the condition of keeping the charges in the electric field unchanged, when the force of the charged body has a component in a certain direction, the movement in that direction will inevitably lead to a decrease in the energy of the electric field......" The more he talked about it, the more he talked about it, completely ignoring the fact that Zheng Jianxue was a scumbag.

"Ahem!" Zheng Jian, who was in a state of confusion, had to interrupt the wandering, "That dean, don't we start from the basics?" ”

"That's the foundation!" Wandering said in surprise.

Zheng Jian:(⊙_⊙; ）

Wandering looked at Zheng Jian's bewildered expression, and finally reacted, "Alas! Let's lay the basics first! ”

..........

On the playground of the academy, Zheng Jian, who had been studying in the wandering area for more than half a month, found Rose and wanted to learn from each other to test his learning results.

In the past half a month of study, Zheng Jian has a clearer understanding of electromagnetic force and has developed it to a certain extent.

"No, no, your attack is completely useless! Don't leave your hands on Rose! On the playground, Zheng Jianzheng and Rose were fighting.

Zheng Jian deliberately stabbed Rose with words, wanting to force out Rose's full strength, so as to test his new skill, the defensive power of the magnetic field.

Through the control of electromagnetic forces, Zheng Jian created an invisible protective force field in and around him to resist most attacks.

"Damn!" After scolding angrily, Rose stepped aside and began to calculate and analyze the magnetic field around Zheng Jian with all her might.

Seeing that Rose had finally moved seriously, Zheng Jian deliberately stopped the offensive and stayed in place constantly changing his magnetic field to fight against Rose's cracking.

Ten minutes later, Rose still couldn't crack Zheng Jian's magnetic field, and could only reluctantly quit the operation mode.

"Aren't you cracked?" Zheng Jian looked at the rose that stopped and asked out loud.

"Humph!" Rose, who was in a bad mood, did not answer Zheng Jian's words, and left with a cold face.

Zheng Jian looked at the back of Rose leaving, and a happy smile appeared on his face, "It seems that the development is very successful!" ”

After testing his new abilities, Zheng Jian, who was beautiful, touched his fleshy belly, walked towards the cafeteria, and was ready to enjoy lunch.

With the privilege of the teacher, Zheng Jian had a big meal in the cafeteria, and then walked to the dormitory with his bulging stomach, ready to take a nap.

In the afternoon, Zheng Jian, who was still sleeping, was woken up by the sound of knocking on the glass.

"Who! Bastard! Zheng Jian got up slowly, walked to the window, and said unhappily.

When Zheng Jianyi came to the window, his eyes widened again, "Another one!" ”

"You're the mysterious creature?" The girl outside the window asked very arrogantly with a pair of big breasts and a tall look.

"Yes, my name is Riri!" Looking at Rena with an arrogant face, the unhappy Zheng Jian deliberately mocked.

Hearing Zheng Jian's words, Rena didn't react at first, but soon her face changed, "Bastard! ”

After scolding, I saw a huge amount of energy gushing out of Rena's hands, and it slammed directly at Zheng Jian through the window.

"Phew! Bah! Zheng Jian, who was attacked suddenly, still looked a little embarrassed although he blocked the attack with a 24-hour full-open magnetic field.

"How dare you offend God?" Through the dust, Rena, dressed in armor, walked towards Zheng Jian angrily.

"Isn't the god of fart a super gene warrior?" Zheng Jian, who was a little angry, released a small electromagnetic cannon directly towards Rena.

In the face of Zheng Jian's surprise attack, Rena reacted quickly and summoned a shield to block the attack.

"Nice attack!" Rena, who blocked the attack, said arrogantly.

"There's even better!" Hearing Rena's words, Zheng Jian pursed his mouth in disdain.

Although Rena is very strong, Zheng Jian, who has a hole card, is not false at all, anyway, if she can't win, she will run!

The confident Zheng Jian fought against Rena like this.

"Boom! Rumble! As the intensity of the two's attacks continued to escalate, various large craters appeared in the open space in front of the dormitory, the ground was covered with rubble, and the air was filled with dust.

"Ahem, ahem! Stop it! The wanderer, who had come from afar, hurriedly spoke out to stop him.

After finishing speaking, the wanderer first looked at Rena, and after signaling Rena to stop, he said to Zheng Jian: "Okay, Garfield!" Don't you want to go to admissions? Rose is leaving, come with her! ”

Hearing the wanderer's words, Zheng Jian grinned, glared at Rena, who had been glaring at him, before turning around and leaving, ready to go to find Rose.

When Zheng Jian left, the wanderer looked at Rena seriously, "Rena, control your emotions, your abilities are powerful and dangerous!" ”

"Got it, Mr. Liu!" Rena said in response.

"What do you think of Garfield's strength?" Wandering did not continue to teach Rena a lesson, but instead asked about Zheng Jian's information.

"It's kind of funny, he didn't go all out, and of course I didn't. And I always feel that he has some hole cards, and he just showed that he is too confident! Rena said fearfully, recalling the battle just now.

After listening to Rena's words, the wanderer nodded lightly and continued: "Okay, Rena, you go back and rest first!" I'm going to take care of something. ”

After saying that, the wanderer was shrouded in a blue light and disappeared in an instant.

Seeing that the wanderer left, Rena also relaxed, turned around and walked towards the dilapidated dormitory, and kept chanting the words in her mouth: "Damn fat cat, this goddess will teach you a good lesson sooner or later..."

On the other side, Zheng Jian, who had received the consent of the wanderer, easily discovered the location of the rose and hurried over.

Rushing to the school gate, Zheng Jian stopped the car in which Rose was riding.

"Garfield, what do you want to do?" Rose asked, looking out of the window, confused.

"Dean Liu, let me go with you!" Zheng Jian walked to the car door and explained.

After listening to Zheng Jian's words, Rose and the colleague sitting in the driver's seat glanced at each other before saying, "Then you come up!" ”

"I've come up, let's go!" While Rose was still talking, Zheng Jian sat in the back seat of the car very consciously.
