Fan Mayong on the side strongly recommended the benefits of being a Yanshi, like what kind of welfare treatment is good, the social status is high, and he can use what he has learned to build the Zhenyuan Kingdom, and when he is fine, he can also make some Yanjia flying kites to play by himself.

Lu Shaoyun's idea is that although he has almost done this before, after all, time and space are foreign, and he has not even figured out the social structure here, let alone whether the physical laws are still the same as before, no, at least he has to calculate whether the gravitational acceleration is a g first.

"Let me think about it again." Lu Shaoyun wants to slow down first, not in a hurry to make a choice, and whether he can enter the top three is still a question? Before the college entrance examination, I was thinking about whether to take the Tsinghua University or Peking University exam, and maybe I would roast sweet potatoes in the end.

Fan Mayong nodded seriously and said, "That's okay, this matter really needs to be considered carefully, I still think this Yanshi ......."

"Is there a timekeeping object here?" Lu Shaoyun interrupted him at the right time.

Fan Mayong was stunned for a moment, and then replied: "Yes, yes, you wait a minute." ”

After speaking, he walked out of the door, and came back after a while, followed by two graceful maids.

Seeing this, Lu Shaoyun looked confused: "Is there something wrong with my statement?" ”

Fan Mayong smiled and clapped his hands, and the waitress behind him walked to Lu Shaoyun, one left and one right, each holding a square sandalwood tray in both hands, a bundle of incense on the left, and a delicate leaky pot on the right.

can make all kinds of precision machinery, the mechanism is armored, the timing tools are still so backward, this technology tree has grown into a crooked neck tree, Lu Shaoyun couldn't help but complain in his heart.

But then again, the organ armor I saw before was not very popular, it was more like a special group organization, and it was estimated that it was controlled by the imperial city, otherwise why had I never heard news of Chen Sheng and Wu Guang's uprising? Maybe there have been in history, but in front of the Yanjia army, it is like a grasshopper shaking a tree, which is not worth mentioning.

At this time, Fan Mayong spoke: "I said that I would send someone to protect you, and in the future, these two personal maids will be sent by you, just tell them to do anything." ”

Then he introduced from left to right: "Cangling, Su Shang." ”

After the introduction, the two waitresses bowed their heads slightly and said in unison: "I've seen Lu Gongzi." ”

Lu Shaoyun nodded politely and smiled slightly.

"I've got a room for you, and you can stay here for a few days." Fan Mayong added, "They will take you around the neighborhood, there are still a lot of fun places in Izumo City, in short, just tell them anything." ”

Lu Shaoyun still couldn't help but ask, "You don't want to ask me what I want to do with the timer?" ”

"If you don't want to tell me, I promise I won't ask." Fan Mayong thought for a while and said, "Brother Lu, it's good to treat this place as your home, feel free, it's okay." ”

After Fan Mayong left, Lu Shaoyun looked at the incense, then at the leaky pot, and decisively picked up the leaky pot and walked out.

He suddenly remembered something, and was about to turn around and ask, but found that the two maids had quietly moved behind him, Lu Shaoyun was slightly stunned, and still asked, "Do you know where it is higher around here?" ”

Su Shang put away the tray and said gently, "Childe, please come with me." ”

The Cang Ling next to him was still quietly holding a tray of incense, with a gentle face.

Su Shang took him to the Guanyun Tower in the middle of the Fan Mansion, Lu Shaoyun looked up, it was as high as seven or eight floors, and it was said to be a building, but it was actually more like a tall tower.

"How tall is this building?" Lu Shaoyun asked.

"Hui Gongzi, this building is seven floors and about ten zhang high." Su Shang replied.

Lu Shaoyun calculated in his heart, one zhang is about 3.33 meters, no, considering that zhang may have to be discounted in ancient times, it seems to be about 2.3 meters, that is, the height of the building is 23 meters.

Lu Shaoyun handed the leaky pot to Su Shang again, and said, "This will be used, right?" Later, I will throw a stone from the upper floor, and you will help me time it, and I will start the timer when I say that you will start, and stop when the stone hits the ground, and then tell me the time when the stone will fall. ”

Although Su Shang was a little puzzled, he still nodded and said, "No." ”

Then Lu Shaoyun began to look around for a suitable stone, the stone is too small and too big is not good, the surface is too rough, and the air resistance factor must be minimized.

Suddenly, he remembered that when he entered the Fan Mansion, there were two stone lions at the door, and the stone lions both had a smooth marble ball in their mouths, wasn't this the dream love stone he was looking for?

However, there is a problem, although the size of this marble ball is moderate, but the quality is not light, let him carry the ball to the seventh floor without exhaustion, although he also thought about getting a pulley conveyor, but at the moment there is a lack of relevant equipment, it is difficult for the Qiao woman to cook without rice, and he does not plan to get it himself.

Fan Mayong said that he arranged a personal maid to protect himself, but in fact he was just monitoring himself, since you asked me to do things casually, then there is no need to use it in vain, and don't blame me for not piping on the jade.

Thinking of this, Lu Shaoyun immediately spoke: "Su Shang, please help me bring the marble ball from the mouth of the stone lion at the door." ”

"Childe, it's just an ordinary stone, it's not valuable." Cang Ling, who had been silent for a long time, suddenly opened his mouth.

Su Shang didn't say anything, she handed the tray and the colander to Cang Ling's hand, and then walked to a side room, and after a while, she had an extra hammer in her hand, and then walked straight to the door.

Looking at her slender back, Lu Shaoyun suddenly felt a little unbearable.

After smashing the teeth of a stone lion with a sledgehammer, a stone ball is removed from its mouth.

The guards at the door looked at each other and were stunned for a long time.

When she returned, she was holding a hammer in her right hand and a stone ball in her left hand, and she didn't breathe, but her face was slightly flushed.

When Lu Shaoyun was about to take the stone ball, because he miscalculated the weight of the stone ball, he almost missed his foot, he quickly stabilized his body, or put the stone ball back into her hand, and smiled awkwardly.

Lu Shaoyun felt that the other party must have practiced, since this was the case, it shouldn't be too much for her to bring the ball to the seventh floor, right?

"Then please help me bring the stone ball to the seventh floor." Lu Shaoyun said with a blushing face.

Then he didn't forget to tell the spirit on the side: "Remember to time." ”

Su Shang stopped and glanced at Lu Shaoyun, although he didn't say anything, but his eyes were clearly saying, "Aren't you entertaining the slave family?" ”

But Cang Ling already had a lot of criticism: "Childe, if it's not something important, I hope you don't embarrass Sister Sushang." ”

"No, it's important." Lu Shaoyun suddenly became serious, "I decided to name my next experiment the Guanyunlou Experiment, haha, the first person to measure the acceleration of gravity, that must be me!" ”

The two waitresses listened to his incomprehensible words, and suddenly became foggy.
