Pei Qi walked to the door of the house, and Mo Qingyan also followed to the door of the house.

She glanced at Mo Qingyan, this man had no intention of leaving at this time.

Fortunately, my uncle was on a business trip today, and there was no one at home.

At this moment, Pei Qi is extremely glad that his uncle is a golden bachelor, and when he is not at home, there is no one in the family.

"Aren't you going to go?" Pei Qi raised his eyebrows and stared at Mo Qingyan, unable to see any of his motives.

Mo Qingyan pouted, in fact, he didn't plan to, but if he didn't leave, he would do too much, and he would be hated.

"Then I'm leaving."

Mo Qingyan turned around and walked away step by step.

Pei Qi's eyelids jumped, and he always had a feeling that he was bullying the weak.

Approaching the study, Pei Qi suddenly breathed a sigh of relief.

Why did I feel wrong after I met that man?

Okay, we only love to learn?

The actor suddenly jumped out from behind Pei Qi and jumped into her arms, white and soft, with big watery eyes, which inexplicably made Pei Qi feel a trace of happiness.

Pei Qi thought of Mo Qingyan inexplicably, pressed his temples, and felt that he was stunned.

Shaking his head and taking out the textbooks and test papers he brought home from school, Pei Qi fell into a state of study.

Nitrogen oxides (NOx) is one of the air pollutants, and NH3 is used to reduce NOx to N2 under certain temperature and catalyst conditions in the industry. Answer the following questions:

(1) Preparation of ammonia

(2) Pre-collect a bottle of dry ammonia gas, select the device in the above figure, and its connection sequence is: generator →______ (according to the direction of the air flow, indicated by lowercase letters).

……

After doing a few sets of exercises, Pei Qi said that he was physically and mentally comfortable.

Continue to study, forget about weekends and holidays, and learn from the wilderness to the old man, semester after semester, and still can't enjoy learning.

Your life as a scumbag is not for me, and indulging in learning is what makes me happy.

It's better to study and worry-free.

The little white cat actor looked at Pei Qi's page with round eyes, Xiao Qiqi likes to study, and he has to study hard, but every time Xiao Qiqi learns, he can't notice him.

After studying the school curriculum for a while, Pei Qi began to think about how to solve the problem of eating.

She should be able to make a set of robots that cook automatically.

Xiao Zhengtai blinked his eyes, so what's the use of his loser system? You can lose, you can come to the system space to exchange for robots!

However, someone does not have this kind of realization.

There are too many technologies in the loser system, except for some old small toys that can be taken out to play, other technologies are not suitable.

Her force value is limited, she can't handle too many people, and to prepare for the future, she needs a lot of robots with attack performance.

Compared with the bodyguard, Pei Qi trusts the robot he made more and will not betray.

Thinking about taking out his phone and ordering a takeout, he began to think about the feasibility of robots in this era.

When it comes to launching at a certain point, it should be able to make a lot of money.

The value of the loser can't be maintained by demolishing the house all day long, and she is tired of dismantling everything at home.

There's really nothing else to tear down.

When he was really busy and dizzy, Pei Qi turned his head and the little white cat could fall asleep on the biology book.

Pei Qi raised the corners of his lips, his eyebrows were full of soft color, and his heart was warm.

At that moment, I felt a little healed.
