Ji Xiaotiao spent the whole day hiding in her room, biting her pen and staring at the exercises on the table with bitter hatred.

"Ah, ah, ah, ah! I"m going crazy. . . "

Is this really an exercise in Grade Two of High School? Did the teacher make a mistake? Why is it so difficult?

She fretfully scratched her head; her black hair was scratched into a straw nest. What should she do? School would begin the day after tomorrow. There was still so much homework left!

Huh? This question. . .

What can solar energy be converted into when the sun heats the ground? Hot air rises and air flows to form wind. What energy does solar energy convert into? Plants absorb sunlight and produce photosynthesis. What energy does solar energy convert into? The sun heats the ground and water, and part of the water evaporates into the air to form rain and snow. What energy does solar energy convert into?

What’s with this problem? What am I supposed to do? How should I know this?

Bang!

She crouched desperately at the table; maybe it would be easier to decide whether or not to have self-determination. . .

I got it! Ji Xiaotiao sat up violently, her eyes sparkling, as if she had thought of something.

Isn"t the guy next door a ready-made walking dictionary? A gifted teenager with an IQ of 245! Although he wasn’t in school, winter vacation homework shouldn’t be difficult for him.

The only issue was . . . would he even help her? What if he just scolded her, called her a fool, and threw her out?

Ji Xiaotiao arrived at Xu Moqi"s door with her homework in her hands. She knocked on the door with courage after hesitating again and again.

A moment later, the door opened. And Xu Moqi, who was 1.82 meters tall, stood in the doorway, coldly looking down at Ji Xiaotiao.

"Er. . .  That. . . "

Ji Xiaotiao couldn"t say why. Actually, Xu Moqi"s height was oppressive to her. Now the atmosphere was so stiff. The young man seemed to be in a bad mood. Was she going to ask for help, or not?

"Cat got your tongue? Or are you an idiot who can"t even talk?"

Either he didn’t open his mouth or he didn’t speak well when he did. Ji Xiaotiao rolled her eyes. She thought that had made the storm get worse. Anyway, she had come to this point. Fight!

……

Taking a deep breath, Ji Xiaotiao looked up at Xu Moqi.

"I, er . . . I haven"t finished my winter vacation homework yet. Can you help me? Please?"

She held her exercise books out with both hands, bowing her head and pleading. She cheered herself in her heart, making a promise. Although she was handing the reins over to him, at least he could help her to overcome her current difficulties.

After a while, she saw no movement. Ji Xiaotiao looked up a little and saw Xu Moqi smiling brilliantly.

What? Is it possible?!

Just thinking about it in her heart, she saw him bow his head slightly. Bending over Ji Xiaotiao"s ear, he uttered two words.

"No way!"

"Xu Moqi, you. . . "

Ji Xiaotiao"s small universe had not erupted yet when the door was slammed shut. “Ah!” There was a scream. A certain someone’s innocent little nose had just taken damage!

"The sun heats the ground and converts solar energy into heat (or internal) energy. Hot air rises, air flows to form wind, and solar energy is converted into dynamic (or wind) energy. Plants absorb sunlight and produce photosynthesis, and convert solar energy into chemical energy. The sun heats the ground and water, and part of the water evaporates at high alt.i.tudes to form rain and snow. Solar energy is transformed into gravitational potential energy."

Xu Moqi sat at the table, and helped explain the exercises to the girl. That was the result of b.u.mping her little nose. d.a.m.n it! How was he supposed to know that the girl was so silly that she didn"t even know to dodge when he closed the door?

Ji Xiaotiao wrote the answer happily, then looked up at him worshipfully.

"What"s in your head? How could it be so smart?"

He glanced at her and was lazy to speak. "Obviously something different from yours!"

With the help of Xu Moqi, Ji Xiaotiao wrote out the exercises like she was receiving divine help. Physics is done, next is mathematics!

Watching someone who’d stared at the exercises for half an hour, Xu Moqi could not help speaking.

"What’s the problem?"

Ji Xiaotiao scratched the back of her head and showed a face of embarra.s.sment.

Xu Moqi accepted his fate once again. "Well, which answers do you know?"

She was speechless, and made the same action.

He nodded."You don"t have to explain it. I already know. The issue is, you don’t even know what the problem is. . . ”

Her eyes sparkled."Wow, you"re so intelligent. How can you even know that? You surely are the super genius with an IQ of 245.”

Xu Moqi grabbed Ji Xiaotiao"s exercises and said, "You! Give me a break now. Come back after fifteen minutes! Whatever you do, don"t disturb me! Do you understand?"

She nodded obediently and saluted him with delight. "Yes, sir!"
