Chapter 394

It is clearly Du Yuan who takes the initiative to tease him. Why refuse him?

Shen Yan's desire has overwhelmed all the other considerations in his brain. He hooked Du yuan's neck and came to him indignantly.

"Well..."

Du yuan just resisted symbolically, and then put his hand into Shen Yan's clothes.

"Ji Chenyan, you answer this question."

"Ji Chenyan?"

"Ji Chenyan"!!! Turn on your camera! "

On several softwares, the teacher drew Shen Yan to answer questions in the studio, but he didn't wait for feedback for a long time. He couldn't even see Ji's real-time actions, so he couldn't help being a little annoyed.

Shen Yan wakes up and refuses Du yuan.

"Never mind." Du yuan's voice is very dull, as if from the eardrum friction.

"There will be points deducted!" Shen Yan pushed Du yuan away, finishing his clothes and connecting the wheat quickly. He said in a hurry, "Miss Yang, I'm here!"

Du yuan looks at Shen Yan's way of answering questions seriously, and he is secretly annoyed. He finally got Ji Chenyan to take the initiative. As a result, the live broadcast software made trouble again!

How about spicy chicken!!!

Du yuan turns back to pick up his mobile phone, clicks into the app store, and makes a bad comment on several apps. He points his finger and writes a comment full of resentment: "anti human existence!"!!! Suppress human nature!! The capital product of all evils! "

Damn it!

If you can score zero, he is too much for one star!!

Du yuan is very angry, but Shen Yan is still answering questions. Although he came out of the cabinet in public before, now with the camera on, Du yuan has no face and no skin to stick to it.

However, I don't feel reconciled when I think about it.

It was the closest home run ever!!!

"The purpose is..." Shen Yan is answering the second question. He feels cool.

He was so surprised that he looked down. Du yuan looked at him with a bad smile.

"Er..." Shen Yan shuddered all over his body, and his insteps were strained.

"What is the purpose of the first washing operation in this experiment?" Mr. Yang was already angry. Seeing that Shen Yan couldn't answer all of a sudden, he scolded, "Ji Chenyan, you are good at examining the topic!! Have you read it clearly? "

Er

Shen Yan suppresses the low breath that is about to rush out of his throat. On the one hand, he suppresses Du yuan's action. On the other hand, he raises his mobile phone so that the camera can only capture his face.

In this case, but also focus on reading chemistry, it is a huge test.

Shen Yanqiang suppressed the abnormality and said in the most normal voice: "the first washing operation is to wash away most of the sulfuric acid and acetic acid..."

Du yuan's heart is dissatisfied, oh, so tense? The voice is normal, even the expression is no different, this is an insult to his technology!

"What is the purpose of the second washing?" Teacher Yang asked.

"Er..." All of a sudden, he was treated so well that Shen Yan didn't hold it back. He quickly covered his mouth with his hand and looked down at Du yuan angrily.

Du yuan raised his eyes to see him, his cheeks bulging, and his eyes were full of successful bad smiles.

"Ji Chenyan!" Mr. Yang raised his voice to urge him.

Shen Yan's whole body is numb, and his fingers go through Du yuan's hair. He tugs at Du yuan's hair with shame and annoyance. Unexpectedly, he hears the latter hiss with pain.

The corners of Shen Yan's mouth were slightly raised, which made him feel better. His voice was a little hoarse. "The second time was to wash off ammonium bicarbonate."
