"You mean...... What creatures are diving into the water in a big boat?"

Qin Fengyi put down the hammer and the little chisel, and looked at Lin Qingxue, who was very frightened, this girl was timid, and she would think crankily when she heard any strange sound.

Yesterday when I explored the ghost ship, I really felt that something was wrong, Qin Fengyi thought it was a mouse on the ship, after all, it was normal for such a big ship to have mice, but the grain brought back was piled up in the bamboo house, the sack was almost not broken, and there were no mouse holes in the granary of the big ship.

If there were rats on the boat, it would definitely turn the granary upside down, so ...... There might be something else on the big ship.

The skeleton that resembled a mermaid appeared in front of Qin Fengyi's eyes at all times, and the bones of a group of human beings seemed to be very unusual to kill even if they were crawling forward.

"You say...... Can skeletons dive?" Lin Qingxue was still thinking about the sound of diving, and Xiao Nizi thought that the skeletons on the deck were alive, and then ...... Diving.

"How can a skeleton come back to life?" Qin Fengyi got up and stroked Xiao Nizi's skull, "Don't think too much, I'll help you hold it when the sky falls!"

"Hmm......" Looking at Qin Fengyi's still handsome cheeks, Lin Qingxue pursed her lips and nodded slightly.

"Qin Fengyi, we also found an alarm clock outside, but there is no battery, I think it should still work. Han Xuening handed the alarm clock to Qin Fengyi.

After taking the alarm clock and playing with it a few times, Qin Fengyi frowned and said, "There is no battery, but it doesn't matter, we still have potatoes!"

"Teacher Han, I guessed correctly, I know that Qin Fengyi is going to use potatoes to generate electricity!" Lin Qingxue seemed to have had some communication with Han Xuening, and at this moment the two girls were muttering quietly.

Came to the small vegetable garden to dig potatoes, today's plants have not yet been born, Qin Fengyi stood in the center of the vegetable garden, another wave of spells.

"Grow up, my sweet little darling!"

[The host successfully spawns plants, and the growth rate of plants within 30 meters diameter is +60%]

There are many plants, among which the fastest and most obvious are watermelons and pumpkins, more than 20 pumpkins are all ripe, these big guys can no longer give birth, continue to urge is estimated to be old.

"Looks like we have to pick pumpkins and cucumbers!" Looking at the pumpkins and cucumbers on the shelves, they are all overgrown, and when you pick them, you can leave a few big, watery melons and fruits, continue to grow, and when it is old, you can leave some seeds, and then plant them again.

The potatoes in the vegetable garden are growing against the sky, and because they have been growing, these large ones completely absorb the nutrients and water in the soil, and one of them has emerged from the ground, and there are round bumps under the diameter of the poles.

Cut off the stem diameter of the potato, and then quickly dig out the potato, there are some bugs in the soil, earthworms are very common in the black soil, and it is not uncommon to dig this thing.

What is strange is to dig up a big white bug, when this guy is wriggling, through the white tender skin can see the black stuff inside, which seems to be its internal organs.

"Let's escape...... "Now that the food is sufficient, if you are so hungry that you can't eat, Qin Fengyi will definitely catch it and roast it and eat it, when you first came to the desert island, you didn't have anything to eat, and you used to eat insects.

Bringing the potatoes back, Qin Fengyi began to test the alarm clock, if the alarm clock can continue to run, try to set a time for it, here each time concept is basically made at sunrise and rested at sunset.

"Qin Fengyi, why do you want to use two different wires? Isn't it longer to use copper wire?" Lin Qingxue watched Qin Fengyi's operation, he was holding the copper wire and the iron wire, which were pierced into the two ends of the potatoes respectively, and then connected the copper wire to the negative pole of the battery, and the iron wire to the positive pole of the battery.

"Potatoes do contain starch, but if you want this to be a battery, you have to use wires of different materials to guide it, otherwise it will not be able to become the output of the battery. Qin Fengyi continued to operate, repeatedly switching the angle and position of the positive and negative electrodes and the potato copper wire and iron wire.

After a few minutes......

"The pointer has moved, it has moved!!" Lin Qingxue pointed to the pointer of the alarm clock that was turning step by step, clapping her hands excitedly.

"There's a watch, we have a watch!" Han Xuening was also very pleased, she was hugging Lin Qingxue, bouncing, the two white rabbits were really good-looking together.

Clock!

The thing that records time is something that has been studied by human beings over many years.

The simplest form of a clock is to erect a small straight branch on the ground, and the shadow of the branch will change with the turn of the sun, and the shadow of the morning and afternoon will be the longest, and the shadow of the noon will be the shortest.

It's hard to imagine that the ancestors of mankind discovered the key to recording time with a simple wooden stick, and then slowly added many things, such as scales and discs, and then developed technology and machinery, and developed the current clock!

The time on the alarm clock shows 3:15, which is the time when the alarm stops, which is inaccurate.

Looking up at the sky, Qin Fengyi glanced at the sun roughly, and then inserted a branch on the ground to observe the shadow of the branch.

"Guess what time it is, and I'm on a pair of watches. Qin Fengyi probably had a guess in his heart, but it was just a very general guess concept.

"Hmm......" Lin Qingxue stretched out her little hand, groped her pointed chin, and was frowning and thinking, she would look up at the sky and the sun for a while, and look down at the shadows of the branches on the ground, "It should be around 9 o'clock ~ 11 o'clock in the morning." ”

"Damn, you've been down for 3 hours. Qin Fengyi was speechless, Lin Qingxue's answer range was too large, and the answer in Qin Fengyi's heart was closer than hers.

"What about Teacher Han, what time does Teacher Han think it is?" Lin Qingxue pouted helplessly, guessing the time, this is very difficult, okay.

"I think...... It should be 10.12 points!" Han Xue Ning thought about it for a while, and nodded affirmatively, "That's right, it should be at 10:12." ”

"You really dare to guess, it's almost a few seconds. Qin Fengyi pouted helplessly, his guess was very close to Han Xuening's, but it was not accurate enough to be like this.

"What time do you think it should be now?" Lin Qingxue was very curious about Qin Fengyi's answer, and crouched down to look at the pointer that had been walking the watch.

"Between 10:15 and 10:40......" Qin Fengyi's guess was mainly based on the degree of hunger, the temperature and position of the sun, and the length of the shadow of the wooden sticks erected in the sun.

After repeated discussions, everyone set the time of the clock at half past ten, and there is a gap in the time of each country, such as the time difference between Huaxia and the United States for a full 8 hours (according to memory, I don't know if it's right).

The clock is placed on the table of the bamboo house, so you don't have to touch it often, so you don't have to worry about damaging the clock.

Of course, the power of potatoes is limited, and it is normal for the clock to stop turning one day.

At the same time, Qin Fengyi's stone mill was also completed, he was doing experiments, the target of the experiment was wheat, and the hoarding of wheat in the bamboo house was enough to weigh tons and could be tossed for a long time.
