In the afternoon of this day, Yan Yan took Lu Jin's dinner in Cining Palace and came out of Cining Palace, Yan Yan went to meet the queen and the crown princess again, so delayed, it was almost dark when he left the palace, and he only knew that Lu You had come back early.

"Why are you home so early?" Yan Yan got out of the carriage and saw Lu You standing in front of the shadow wall, and was startled.

"So many things again?" Lu You took Lu Jin, and when he saw Qingyu constantly moving things down, he asked casually.

The two asked almost at the same time, then looked at each other and laughed.

It turned out that Lu You came back in advance to tell Yan Yan that the gunpowder spray cylinder had made progress, and it could spray about half a catty of gunpowder seven or eight feet away, and after it landed, the gunpowder also exploded.

Although this distance was too far from their expectations, this was already a breakthrough, because the previous one could only shoot two or three feet away, and there was even an accident where the gunpowder of the spray barrel exploded, and it almost injured people at that time.

However, there is also a problem, the bamboo tube will produce a kind of retreat force when the gunpowder is sprayed out, the farther the gunpowder is ejected, the greater the retreat force, for this reason, they are worried that if the gunpowder is really sprayed out ten or twenty feet away one day, this person should not be shocked away, right?

"Husband, there is, you think, we usually use two bamboo tripods to fix the bamboo poles, usually blowing so strong wind, that is, the clothes will be blown away and the bamboo poles will be blown off, but it is rare to blow the tripod over, it is better for you to try to find a way to fix the spray canister on the tripod, and in this way you can also avoid the damage caused by the explosion of gunpowder in the spray canister. There is one thing, I also came up with this idea by chance, and I can't guarantee whether it will work out. Yan Yan reminded.

"Makes sense." Although Lu You has never dried clothes, he has seen clothes drying in the yard, which seems to be the same thing.

"Lady, you are really my Zhiduoxing, every time I encounter a problem that cannot be solved, you can always point me in an unexpected way." Lu You held Lu Jin with one hand and freed up the other hand to hold Yan Yan.

"What's this, it's just a coincidence. By the way, husband, don't tell outsiders these words, just say that you thought of it when you went home and saw the yard drying clothes, I don't want to be doubted by others anymore. Yan Yan admonished.

Once or twice may be accidental, but too many times will inevitably arouse suspicion from the outside world, not to mention others, the emperor will test her a lot.

Lu You was entangled for a while, but quickly agreed, but didn't ask the reason, but took the initiative to change the topic and asked her why she came back so late.

Only then did Yan Yan tell him that he was going to Yan's house for a banquet tomorrow, and he also said the arrangements for his family to be treated, and at the same time he also said the Queen Mother's thoughts.

"Today, our mother really moved the Queen Mother, and gave this little thing a bunch of good things before leaving, and said that I would often take her into the palace to go around, I am afraid that the Queen Mother will regret it if she goes too much." Yan Yan pursed his lips and smiled after speaking.

Not only the queen mother, but also the queen and the crown princess also rewarded Lu Jin with a lot of good things, mainly because Lu Jin's mouth is too sweet, she can speak, and she is not strong when she plays with Li Xi and Li Ran of the same age, on the contrary, she will also take out her toys and share them with others, so the princess is reluctant to let go when she sees her.

In fact, Yan Yan was like a mirror in her heart, the reason why the queen mother, the queen and the crown princess asked her to often take Lu Jin into the palace was to put it bluntly, she wanted to investigate Lu Jin's character, and it was estimated that the dragon pendant given by the emperor made them unable to let go.

Of course, it is not excluded that the Queen Mother may really have family affection for Lu Jin at a certain time in her heart, because Lu Jin can evoke her memories of the past, according to her, the original owner was almost like Lu Jin when she was so old and began to enter the palace with Mrs. Yan, and the original owner at that time also loved to talk and laugh, and even older would sing a little hometown tune to her.

Lu You pondered for a while before he understood the meaning of Yan Yan's words, so when he saw the smile on Yan Yan's face, he was very puzzled, and at the same time a little hesitant, "Didn't you like to bring Jin Niang into the palace before?" Why did you change your mind now? ”

Yan Yan heard this and knew that her husband must have thought too much, "I didn't change my mind, this time it was the Queen Mother who specially asked about Jinniang, saying that I hadn't seen her for a long time, so I took her there, husband rest assured, if I can avoid it, I will not force my daughter to go to that kind of place, but everything must be planned in the worst direction, if we can't avoid it, we should also teach our daughter some skills to settle down, do you know what I mean?" ”

These words reminded Lu You of the night he and Yan Yan got married, Yan Yan was probably the first bride in the capital who dared to negotiate terms with her husband on the wedding night, the reason is that in addition to the fact that he is too useless as a groom, the bride's intelligence and ability are also her confidence, because Yan Yan has absolute confidence that she can support herself and does not have to be attached to anyone.

"Lady, I understand, I'm short-sighted." Lu You quickly admitted his mistake, and at the same time, he was still a little ashamed in his heart.

Fortunately, Yan Yan didn't dwell on this topic, but talked to Lu You about the battle situation between Yan Peng and Yan Ai.

While talking, the family of three entered the backyard and played with Lu Jin for a while, Lu You took a book and went to the inner room first, because he planned to try it in the spring next year, and now it is only three months away from the scientific examination, but he still has a lot of notes and righteousness that he has not understood.

It is also his bad luck, it turns out that the scientific examination of the Great Zhou is divided into three levels, the first level is the state test, the content of the examination is mainly based on the Ming Sutra, the Ming Sutra and the Moyi, these two basically rely on the strong memorization and recitation, especially the Sutra, even the annotation is not used, as long as the original text can be recited.

After the state test, it is the provincial test, and the provincial test is presided over by the Ministry of Rites, and the main content is also the scriptures, Moyi and poetry, and there is also a policy question, which accounts for a small proportion.

The last level of the examination is the palace examination, and the content of the palace examination is more lively, mainly based on policy discussion and policy questioning.

It is said that the state and provincial examinations have been jointly proposed by the three prime ministers, saying that the state and provincial examinations are too simple and impractical, especially now that there are frequent wars, coupled with floods for many years, and a lot of internal and external troubles, it is even more necessary to admit some talents who can be of great use.

And the people who can be of great use are certainly not those who can memorize a few books and five classics, but those who can apply the scriptures, that is, those who can deeply understand the essence of the books and find the concepts and methods of governing the country from them.

And a person's ability and specialty cannot be seen from the Ming Jing, and can only be glimpsed from the strategy and questioning.

So Lu You also knew that his previous advantage could no longer be an advantage.
