The bell tower is built.

Another drum tower has the same style and size as that of the bell tower. It is equipped with a large drum hanging inside, with a diameter of 3 meters and a thickness of 1.6 meters.

This is a huge drum.

Ye Qing chose mulberry trees that have grown for many years.

When making drums, he didn't know what kind of wood is good.

Then he adopted the principle of proximity and selected a dead mulberry tree that had been cut down by the tribe.

He just wants to save time.

This mulberry tree is already very dry, and it is much less likely to deform and crack.

The diameter of the mulberry tree is naturally not as thick as three meters. He made the mulberry tree into plates and then spliced ​​it into a drum body like a wooden barrel.

The drum skin is made of elephant skin.

The buffalo skin is covered with drum, a little small.

Fortunately, some tribes have hunted elephants, and some of them have been preserved.

After the drum was made, the sound of beating was very thick, and Ye Qing was very satisfied.

After completing the bell and drum tower, the most important building on the rooftop is the Water Transportation Camera Platform.

The water transport instrument station is both a mechanical device and a building.

When Ye Qing made a water transport gazebo platform, he would naturally not be as complicated as the one made by Su Song of the Song Dynasty in history.

He used a large number of bronze cast gears, bearings, and other parts, which simplified the structure of the water transport gazebo platform and the final size was much smaller.

Although he has simplified the design a lot, it still took him more than a month.

Moreover, a large amount of casting and polishing work was completed by the tribe members.

He just made casting molds for various parts, which made him so busy.

This is still the case when he has gold fingers.

If you are an ordinary person's hand speed and dexterity, it will take more than a year to make the casting mold for these parts.

At the Water Transportation Camera Station, Ye Qing still abandoned the use of wood. The shell and load-bearing columns are all made of blue bricks, while some of the internal beams are made of bronze beams, and even the internal floor slabs are made of copper plates.

In the end, the bronze used in this water transport instrument station was in the amount of four or five bronze bells.

The copper ingots that the tribe had accumulated for several months were consumed again.

After all the spare parts are ready, it takes not much time to assemble and build them. The construction takes only a few days to complete.

This is a platform that approximates cubes.

The bottom is a square with a side length of five meters, and the side length of the platform at the top is slightly smaller, and the height of the entire platform is also five meters.

The top platform also has a ceiling that can be opened and closed at will.

This is to prevent rain and observe astronomical phenomena.

The ceiling closes when it rains and opens when it is observed.

Extremely convenient.

The final completed water transport cabin is a mixed copper brick building.

This is the most luxurious time when Ye Qing used bronze.

This is also the biggest test of Ye Qing since time traveling.

He didn't need to use his brain to the inventions and creations he had made in the past, they were commonplace things, so where did he need to think?

This time, the production of the water transport instrument station took a lot of energy, calculation, thinking, reasoning, and even experiments...

After the manufacturing of the water transport meter station was completed, he specially made several sets of copper plate design drawings to keep as souvenirs, which was also convenient for the tribesmen to learn. After all, the maintenance work in the future still needs to be done by tribesmen.

If one day the water transport gazebo platform fails and he is not in the tribe, wouldn’t the tribe stop operating?

This water transportation gazebo platform is related to the work and rest time of the tribe.

The water transport instrument station is stopped, but time cannot be stopped.

Once the water transport instrument station stops operating, the work and rest of the tribe will be completely chaotic.

Ye Qing was a little confused about this.

Shouldn’t the work and rest time of the tribe members be so rigid?

As he invented and created more and more machines, the operation of the entire tribe became closer and closer.

Many times, if a problem occurs in one link, a series of subsequent major problems will arise.

The feeling that the tribe is becoming more and more like a closely-run clock, and all the time and work flow of the tribe are closely connected.

Is this right?

But then I thought about it again, this is also an inevitable thing.

If the tribe develops quickly enough, it can only work hard to improve the productivity of the tribe.

This situation is naturally inevitable.

However, this also reminded him that when formulating many rules, systems, and work plans, he needed to leave a margin and arrange backup plans and measures to allow the operation of the tribe to have certain fault tolerance and avoid problems in one link, which would cause huge chaos in the tribe.

Therefore, Ye Qing did not abandon the original sundial and hydraulic crawler, but moved it to the rooftop to allow it to continue running in case.

After the water transport instrument station was created, the most excited person was the patriarch.

This device that Ye Qing once mentioned is fatal to the temptation of the patriarch.

What he most expects is that this device can distinguish seasons and seasons.

Can identify the time!

This is knowledge that only the witch king of the Dayu Kingdom mastered.

Although the great witches from various countries can distinguish the time, that way of distinguishing is simplified.

Why can no one in all countries distinguish the time of the sky in this way?

The patriarch did not know whether the Witch King of Dayu Kingdom understood the truth, but this method was spread by the Witch King. I think the Witch King must know more than the Great Witch King of various countries.

Now that the Fangfeng tribe has this device, the seasons and seasons are no longer necessary to rely on others.

This made the patriarch's face full of redness and his spirit even more refreshed, as if his size had become much taller.

For the school-minded patriarch, he was naturally eager to ask Ye Qing about how to distinguish the weather through this device.

In fact, this instrument water transport instrument station is very simple to operate, and it is completely fool-like.

The operation requirements are that water flowing to low places needs to be transported to high places and regenerate potential energy, and there is no need for any human interference in this operation.

Reading the result is just as simple.

Seasons and time are automatically displayed.

Just like modern people read clock data.

However, the display of the water transport console relies on a rotating panel, rather than digital hops like electronic watches.

The real difficulty is the operating principle of this water transport mesh.

If you want to explain the principle clearly to the patriarch, it would be a huge systematic project.

In order to make a more intuitive explanation, Ye Qing pinched a solar system model with his hand.

"This starts with the entire solar system..."

"The sun, the moon, the earth, the ecliptic, the equator..."

“…”

"In this way, you can rely on this device to observe astronomical phenomena, distinguish the seasons, and calculate the time!"

The patriarch was stunned.

The witches from various tribes who were watching around were also stunned.

Dozens of black mouths appeared around Ye Qing.

They could understand every word Ye Qing said, but they could not understand a single word together.

Is there no heaven in heaven?

Only nothingness?

To them, Ye Qing's words were the real book of heaven.
Chapter completed!
