Li Yue completely devoted his body and mind to doing the problem.

This daughter-in-law of a science and engineering bully looks pretty good when she works hard, well, the more I look at it, the more I like it.

After Li Yue finished the question, he took out Huarong Dao again.

Zhang Yang looked at it curiously, "Didn't you lose this thing?" ”

Li Yue smiled and said, "It's a pity to lose it." ”

After speaking, Li Yue began to move the squares in Huarong Dao, her little face frowned, and she moved extremely carefully.

After a long while, Cao Cao finally walked out of Huarong Dao.

She jumped into her arms excitedly as she watched her success, "I did it!" ”

Zhang Yang looked at her and said, "Some formula conversions and operations in science also exercise logical thinking skills. ”

Li Yue smiled so much that his eyes became crescent-shaped.

Growing so fast before you know it.

Zhang Yang thought about it, maybe Li Yue himself didn't expect that his logical derivation ability had become very strong.

This kind of progress happens without you noticing, that is, you are exercising again and again while doing the problem.

Li Yue took out another Rubik's cube, the Rubik's cube is relatively small, which is three times three, and there are nine grids on one side of the hexahedron.

Because the precision of the tool is not enough, this level can only be achieved at the moment.

In the past, the Rubik's Cube also made Li Yue crazy.

Now she stared at the Rubik's Cube with a solemn gaze, the six blocks of different colors had not been put together since the last time they were scrambled.

After a careful turn, she fell back into deep thought.

After a while, turn it again.

Zhang Yang grinded and preserved some saltpeter and observed Li Yue's expression.

She turned the Rubik's Cube again, and her expression became more and more focused.

It was rotated more than a dozen times in a row, and finally by the last turn, the color of the six sides was complete.

Li Yue's face was full of a sense of achievement.

This is the embodiment of logical derivation ability, which is unconsciously improved when doing problems.

This is a change that she may not have noticed herself.

When she comes back to her senses, maybe she will be shocked to realize that she has done something that she couldn't do before.

It has not been in vain to bury one's head in the past few months.

Her learning ability is really strong, if it weren't for mathematics, she didn't know she had this talent when she did some math problems.

In the evening, I made another meal of wine-stuffed balls to celebrate Li Yue's progress.

There are still some lees left in the jar.

Zhang Yang was busy in the kitchen, making two more scallion pancakes in addition to wine-stuffed balls.

After the two bowls of wine-stuffed dumplings were ready, Li Yue tasted them carefully and said, "Why don't you drink?" ”

Zhang Yang said: "How good it is to make balls with wine, and you can resist hunger, but you won't be too drunk." ”

Li Yue raised his chin, "You're just afraid of getting drunk." ”

Zhang Yang said earnestly: "Drink in moderation, otherwise you will become a little drunkard." ”

"Don't you like me drinking?"

"I'm here for your health."

"Hmph, that's all an excuse for you to cover up your poor drinking."

Zhang Yang ate the pancakes without changing his color, showing no signs of being seen through by her.

At night, after the couple washed their feet together, Li Yue returned to his room.

Not long after Zhang Yang fell asleep, Li Yue slipped into the room again, and then got into the bed very openly.

Actually, tonight is quite warm, and her hands and feet are not very cold.

Oh, she just wants to sleep together.

The two snuggled together.

In Zhang Yang's heart, there was a big knife that kept swinging.

All night long, Zhang Yang silently recited in his heart: calm, calm, slash the heart demon, slash distracting thoughts, slash, slash, slash, slash......

In a daze, he seems to be asleep, but not completely, and occasionally has dreams.

When I reopened my eyes, it was already dawn.

Zhang Yang got up early and started cleaning the yard.

There were still a lot of raisins left, and Li Yue seemed a little reluctant to eat them.

Grabbing a handful of raisins, Zhang Yang sat in the yard and ate, blowing the cold wind of the early morning in winter, there is no sun today, and the weather looks like it is going to rain.

This winter, it was unusually cold and rainy.

Yesterday it was warm, but this morning there was a shivering northwest wind.

At this time, there is still cold air coming from the northwest in Guanzhong, which is really rare.

It's also a good thing, the larvae in the fields can freeze to death in the cold in winter, and the next year should be another good year.

I don't really want to go out today, so let's get the recipe for the fireworks right now.

When breakfast was ready, Li Yue got up and brushed his teeth sleepily, and then washed his face and hands to eat.

Pay attention to hygiene, you must wash your hands before eating, and the little daughter-in-law's habits are good.

Li Yue ate a bun and said, "Did you steal my raisins?" ”

Zhang Yang, who was tinkering with saltpeter, coughed twice, what is it called stealing raisins, your raisins are what I made, okay?

So possessive.

"The weather has been humid lately, so I'm just going to help you see if it's broken." Zhang Yang explained calmly.

Each finished material is put into a bamboo tube at a time, then compacted, and a hemp rope coated with wax oil is used as a lead.

Zhang Yang placed it in the corner of the wall, then lit the fuse, and stood in the distance watching intently as the fuse burned into the bamboo tube.

Li Yue also looked at it.

The lead has burned out, and the bamboo tube is beginning to smoke.

A few breaths passed, and the bamboo tube did not move at all.

Li Yue was curious, "What is this?" ”

Zhang Yang still looked at the bamboo tube, "Artillery battle." ”

Li Yue: "What is the artillery battle?" ”

Zhang Yang: "You can't eat it anyway." ”

Li Yue: "......"

A few more breaths passed until the bamboo tube stopped smoking and the burning inside was over.

Zhang Yang stepped forward, opened the bamboo tube and looked at the burning situation inside, the smell of gunpowder smoke was very pungent.

Then write down your own experimental records, the first cannon duke, the experiment failed, the reason for the failure: the ingredient ratio is wrong, and the ratio needs to be re-proportioned.

The proportions were readjusted, and Zhang Yang did another artillery battle.

This is like crossing a river by feeling the stones, and you can only adjust the proportions again and again until you succeed.

Lighting the fuse again, Zhang Yang watched the fuse burn, and the smoke with the pungent smell of gunpowder smoke came out again.

After a while, the whole bamboo tube burned again.

Zhang Yang shook his head wistfully and wrote down the experiment record again, and the second artillery battle burned as a whole, and the experiment failed......

The third time, the artillery battle kept emitting white smoke, and it stopped for a long time, causing a large area of smoke in the yard.

It lasted about three minutes, and there was still no explosion, and the third artillery battle, the experiment failed......

Three experiments filled the yard with the smell of gunsmoke.

Li Yue covered his nose, "So this is specifically used to create a stench?" ”

Zhang Yang nodded and said, "Actually, this gunpowder smoke can repel insects, um!" ”

Sure enough, behind every success there are countless failures.

Failure is always the mother of success.

Li Yue looked strange, "Do we have worms in our house?" I've always cleaned up pretty cleanly. ”
