Tianling watched Lord Song circle around a large number of things in the courtyard, and had a special sense of cuteness.

So he went into the house and moved a small bench, and sat on the side to watch Lord Song knock and beat.

As a little eunuch who runs errands, Tianling is only responsible for delivering things and passing words, although Lord Song has not avoided him, but what exactly is something Tianling does not know, at this time, sitting on the side and watching Lord Song sweating profusely tinkering with various wooden boards, Tianling remembered the scene when he was tinkering with those bottles and cans in the laboratory.

What a nostalgia! Those days of research!

"Zuo Wen, connect this to that board." Lord Song handed Zuo Wen a wooden handle.

"Pick this up and stand it up."

"Go over there and hold on."

"I'll go to someone to hold it later."

"Ahead, ahead!"

……

Looking at the shelf that could be erected immediately, it was about to fall to the ground because no one in front of him grabbed it, and Lord Song was so anxious that his voice broke.

In a hurry, Tianling didn't care about his small body, ran forward to grab a corner of the shelf, and helped to hold the shelf, although the wooden shelf is not a behemoth, but for a child of Tianling's age, it is still a little difficult to hold on.

Tianling's face was so red that he didn't dare to let go, and he didn't let go until Lord Song fixed his four legs.

"Thank you little father-in-law, Tianling, you helped me a lot just now, come, wipe your sweat." Lord Song took Tianling over, and stretched out his hand to wipe the sweat on Tianling's face.

"Don't, don't, sir, go ahead and get busy! I'll just wipe it myself! Tian Ling looked at the five gray-black finger prints on Lord Song's head, and dodged again and again.

However, Lord Song took advantage of the height and physical strength of adults, and his palm was directly pasted on Tianling's face, and then Tianling was lifted to the small bench and put down, looking at Tianling's face in an instant, Lord Song was very satisfied, laughed and returned to the middle of the courtyard to continue tinkering with his things.

Celestial Spirit: ......

Zuo Wen, who was free, couldn't stand it anymore, took out a handkerchief and handed it to Tianling, "Don't blame the little father-in-law, Lord Song likes you like this, His Majesty has limited him to three days to make a tool to remove the fine debris in the grain, and he is worried." ”

"Debris in the grain?"

"Yes, there is a painting from the Southern Elephant Kingdom, which is the one sent by the little father-in-law yesterday, and lies that they have made it, these shameless subject countries, provoking, Your Majesty ordered Song Dafang to do this." Zuo Wen also had a good impression of Tianling now, and when he saw that he was puzzled, he explained.

"Didn't you remove the debris from the grain before?" Heavenly Spirit asked.

"Yes, it is sieveed and dusted, and it is time-consuming and laborious, after His Majesty succeeds to the throne, the Ministry of Industry is required to report several practical new appliances every year, and Lord Song is talented in this area, and he was specially promoted by His Majesty." Zuo Wen continued.

Tianling nodded, deeply convinced, science and technology are the primary productive forces, and they can be applied at any time.

In his last life, he devoted himself to the research of social sciences and agriculture, and he took a fancy to the practicability of these two disciplines for people's livelihood.

Looking at Lord Song, who was smiling and sad for a while, Tianling didn't think that he was a nervous disorder, how similar he was when he was doing experiments before! Tian Ling spontaneously developed a kind of understanding and kindness, thinking like this, Tian Ling wanted to help Lord Song.

Grain debris removal?

Tian Ling searched his memory in his mind, in his previous life, he was only responsible for the process of grain crops from seed to maturity, and he only cared about the growth and yield of crops!

The only thing I remember about harvesting and handling the crops when they are ripe is that the students with them are running back and forth in the experimental field with the harvester......

Carefully going back and forth a series of knowledge such as various social human resources and crop growth and development laws and environmental ecology, it is impossible to deny the fact that there is a knowledge gap in mechanical manufacturing.

Create something with your bare hands, and look cool X? Inexistent!

……

Lord Song, please ask for more blessings! I can't help you with my major!

And Lord Song is worthy of being a mechanical expert, and directly restored the objects on the painting directly with a wooden board, and Lord Song asked people to pour a basket of rough grain into it, but what the rough grain looks like in and what looks out, the shape is made, but it is useless!

Lord Song dismantled the shell, added a few more boards and nailed them diagonally inside, made a stepped passage to make a compartment, and then poured a bucket of rough grain into it, and then the rough grain came out from the two outlets, and the grain and sundries were still mixed together.

"It's not going to work, just pouring things in and putting them out, it doesn't work at all." Tianling squatted and pulled the rough grain piled on the ground, and said to Lord Song.

"It's better to sift it clean." Lord Song frowned.

"Sieve, by the way, Zuo Wen, dismantle the edge of that sieve, and then give me the net!" Lord Song dismantled the sieve, stuck the screen into it, and poured in the untreated rough grain, but it was all blocked in the wooden box, and it couldn't get down at all!

……

I tried many methods, but they all failed.

It was getting late, but Lord Song had no intention of sleeping, so he directly picked up the lights and fought at night.

Tianling was okay and also helped on the side, but in the end, the child's body began to get sleepy after staying up for a while, so Zuo Wen found a mattress and spread it on the Luohan bed in the Ministry of Works, so that he could rest first.

Tianling opened his eyes and came out of the courtyard the next day, and saw Song Daren Zuowen and them lying in the courtyard, Tianling's face was full of black lines, if it wasn't for the snoring all day, I thought this was the scene of the murder!

Fortunately, this is summer, and they are all men with strong blood and blood, otherwise they will get sick if they lie on the ground all night.

Tianling had experienced death, so he cherished the life he was living even more, and thought like this, he went to the dining room, asked for a few side dishes and porridge, and brought them back to the courtyard of the Ministry of Works.

Hearing the sound, Lord Song was the first to wake up, saw the heavenly spirit, and beckoned, "Little father-in-law is awake?" ”

"Well, Lord Song worked hard, I went to the dining room to order breakfast, eat some and be busy." Tianling handed the food box to Song Ke.

Song looked at the steaming porridge and side dishes, and felt ironed, no wonder he was chosen by the emperor to serve at such a young age, it was so sweet!

"How did Lord Song get out last night?" Taking advantage of Song Qi's meal, Tianling looked at the wooden shelf and asked.

"To no avail." Song shook his head, "I tried to use a sieve dustpan, but it just changed its appearance, and it was essentially no different from a sieve dustpan." ”

Tianling's eyes rolled, thinking of those electric machines that removed dust and impurities in the previous life, in addition to adding crushing and sifting, there was also the use of wind to separate, right! Wind power!

Wind Valley Machine! Tianling suddenly remembered that once when she was sampling in a mountainous area, the wind valley machine used by the local people used to rotate the wind blades with their hands, and the wind generated separated the deflated grains of the grains!

Tianling slapped his head, why didn't he think about it earlier!

How do you tell Lord Song? Tianling pondered for a moment and said: "My lord, I went to the dining room in the morning, and the wind blew a lot of leaves, and I thought at the time, fortunately, the leaves are not stones. ”

Song was stunned for a moment, and then looked at Tianling directly, his eyes lit up!
