With Li Tai's on-site assistance, this open class went smoothly. Baidu search literature network, more good free reading.

Ding Yi took out the convex mirror and staged a nameless fire

Then he drew a diagram of the light concentration on the blackboard.

Then there is the concave mirror, or the schematic diagram is drawn.

After the public class, Li Tai became a sweetheart, and the research institute was frequently visited by students, which was tiring to the craftsmen

So many people want concave mirrors and convex mirrors, this project is a bit big, and in the end, in order to meet the students' enthusiasm for learning, Yin Zhiming applied to Xiao Qing to make it in the glass workshop, and the workshop can now directly make finished products, and it is very convenient to polish them.

Ding disappeared as soon as he finished class, and he brushed off his clothes, hiding the taste of merit and fame.

Li Tai didn't come out of the lab now, and he didn't go to class

Because after using the telescope, Li Ke put forward an idea, if this thing is used in the army, can it be able to anticipate the enemy's opportunity

The two brothers basically lived in the laboratory, and the two of them did not give up, wanting to pull Ding Yi into the water, because Ding Yi said that Li Tai's telescope could see a little close

And Ding Yi persuaded the two of them with great truth, if this thing was made by the two of them themselves, it would not be rewarded for giving it to His Majesty, and even looked at it differently.

If he joins in, His Majesty will definitely think that he made it, and the effect will not be so obvious

However, Ding Yi still promised to give the two of them some knowledge and theoretical help, and every day after dinner, the two brothers would be seen dragging Ding Yi to the study to learn about light.

For more than ten days, Ding Yi was so annoyed that he wanted to beat the two out every time

On this day, the two did not come, and the dinner was sent by Duhe and them.

But Xiao Jian came

Shiping's mansion has a more complex secret room than Chang'an, and the door to enter is in the treasury, which is also where Ding Yi stored gold and silver. Baidu search literature network, more good free reading.

Turning around, he dodged the traps of the unknown number and finally arrived in the secret room.

This is no longer the mansion, but the underground of the National Police Department

Xiao Jian leaned quietly against a wall, his right arm on his stomach, his left arm on his right arm, and his left hand supporting his left face.

"Have you read some books that you shouldn't have read recently?" Ding Yi said speechlessly.

This kid said that his knowledge is shallow, and he has to go back to Ding Yi's study from time to time to take some storybooks. Those were some martial arts that Ding Yi recalled in his spare time.

"Hehe, young master. No, I'm thinking about it," Xiao Jian said with a hippie smile.

Ding Yi doesn't care about these things, this kid has learned badly

"How's it going?"

Xiao Jian immediately became serious, and said with a solemn face: "The person has found it, but he can't get close." ”

"What's going on?"

"Speaking", Ding Yi had a bad premonition.

"Ding Sen was accepted as a concubine by Cui Bin." Xiao Jian was embarrassed.

"Smack"

This time, it's really the nameless person who grabbed me and got straight to your bed

It's revenge for why I just want to involve innocent people

After "how is Ding Sen" calming down, Ding Yi is no longer entangled, it's good that people are fine, and being a concubine of the Cui family is better than running around all day long.

"I can't approach it for the time being, but I heard that the people of Cui Mansion said that Ding Sen lives alone in a separate courtyard and is being served."

"Figure out Tinson's situation as soon as possible, if it's her voluntarily then let her go, if"

"Got it"

"Young master, we found out some news from the remnants of the previous dynasty."

"Say"

Originally, they caught the groom, thinking that the clue was broken, but by chance a nail was inserted.

According to the news from the nail, these people seem to have made a big move some time ago, but they haven't found out what it is.

And recently, the gang of bandits has run to the border

"Go deeper, as long as the intelligence" Ding Yi gave instructions for the spy, he didn't think he had the ability to destroy these people, and there was no need, leave it to Li Er to have a headache for himself.

Ding Yan is already fine, but he is a little lame when he walks. Now I'm just in charge of trading the market, and I'm free every day.

It's just that he is unwilling to live like this in his heart, and his heart has long run away with a girl

The young master had promised him to find Ding Sen, and he would ask every few days, and today was the same, he came to Ding Yi's study again.

"There's news"

As soon as Ding finished speaking, Ding Yan pounced on the desk and hurriedly asked, "Young Master, where is Ding Sen, why didn't she come back?"

Ding Yi can also guess the things between the two of them, when he first assigned people, Ding Yi thought that someone would make a couple, and he was also happy to hear about it.

And Ding Yan and Ding Sen became the most unfortunate couple

Acquaintance, acquaintance, love.

They were all ready to report to Ding Yi and then get married, but God didn't fulfill people's wishes

"She's doing well, I want you not to worry." Ding Yi didn't want to hit him, this was a person who was loyal to him, because his own affairs made him end up like this, if he hit people again

"Young master, don't comfort me. Is she dead?" Ding Yan saw Ding Yi's embarrassed expression, and his heart was sad, and he actually cried for a while.

"She's not dead, it's just"

"Young master, just tell me, no matter what the result is, I will accept it."

"She, she and Cui Bin's concubine" Ding Yi was ruthless and told him the truth directly.

Ding Yi has not experienced any ups and downs, except for crossing over to the Tang Dynasty.

He couldn't understand Ding Yan's mood at the moment, but he could see his loss and even some despair from his expression and eyes.

This kind of sentiment Ding Yi has also had a similar one

After being dumped by his ex-girlfriend

It was his first girlfriend, who had been in love for more than 20 years, and was in love for the first time, and was ruthlessly dumped by someone, and he didn't even know the reason.

It's not necessarily the kind that makes a lot of jokes and makes people laugh

After coming out of the shadows, he regretted that what he had done at the beginning was completely embarrassing and unworthy

said that it is unforgettable, and the scars of the beginning have been erased in a few years, but subconsciously I occasionally think of the original person.

The current Ding Yan may be slightly different from himself, but it is not much different.

"I've asked people to investigate, if Ding Sen is forced, I won't let Cui Bin go. If the

"I hope you can accept that it's not a way to get better." This is Ding Yi's concept of love, he just wants to persuade Ding Yan, and he doesn't want him to be decadent.

However, Ding Yan did not respond.

Long

Poof

Ding Yan knelt on the ground

"Young Master, Ding Yan thank you for your cultivation, it's just that Ding Yan wants to find out the truth by himself, no matter what happens afterwards, Ding Yan will come back. For the young master to go up the knife mountain and down the sea of fire, this life was originally given by the young master, and it will be returned to the young master at that time."
