let go of that priestess

No one closed their eyes and covered their ears, but all of them stared their eyes wide open and their ears pricked up.

What a joke, this is the moment to witness the miracle with your own eyes and up close.

Ji Cheng shrugged, it was time to be reminded.

He put one hand on Honglian's shoulder, and Honglian was ready to release magic at the same time, one person and one dragon at the next moment.

The flash came suddenly, followed by the roar.

The enhanced version of lightning magic accurately split on the iron block, and the wood used to fix it below turned into coke.

Ji Cheng stepped forward to pick up two powerful magnets that were bathed in lightning.

It feels hot to the touch, but it has the power of a dragon to block damage and is fearless.

After adjusting the direction of the magnetic poles, he put two powerful magnets facing each other, and Dragon Force forcibly pressed down one of the magnets, and then let go.

Without warning, the magnet was 'bounced' high by an invisible force and fell to the side.

Seeing this scene, the scene was quiet, Hong Lian's eyes flashed, looking at Magneto, then at Ji Cheng, and the eyes of the team members stared even wider.

Ji Cheng smiled, picked up the magnet again, and this time put one of the magnets on the ground and the other directly above it, using both hands to help balance.

The phenomenon of magnetic levitation appears, and the performance is more intuitive.

Then he turned the upper magnet to its magnetic pole, and the magnet on the ground below instantly sucked itself up, with a bang and a loud bang.

This sound seems to be the final word for today's popular science experiment.

Ji Cheng paused, looked up at the crowd, met shocked and excited gazes, and finally asked:

"Does magnetism exist?"

"exist!"

The 150 people answered thunderously, no less than the previous lightning roar.

Ji Cheng nodded: "Very good! Then the magnetic force exists, and the magnetic prospecting mentioned earlier is established.

After the magnet cools down, I will hand it over to you, so that you can experience this power for yourself, and at the same time, you can make your own prospecting tool in the future—the magnetic needle compass. "

Chapter 192 Find More Wives Quickly

With two powerful magnets, the magnetic needle can be artificially magnetized——

Using the magnetic field of the magnet, the arrangement of the magnetic domains inside the needle tends to be in one direction, so that the needle shows magnetism.

To put it simply, it is to grind the small diamond-shaped iron needle made by Ji Cheng on the magnet for more than 20 times in one direction.

The friction magnetism method is quite simple, but it brought a very practical magnetic pointer to Damimura, as well as the enthusiasm of the team members for prospecting.

Under the guidance of adults, I made a magnetic needle by myself, and made a compass by dividing east, west, north and south.

All the compasses point to the same point, and they deviate from different angles in front of the various ores that the adults took out, amazing!

At the end of the morning, when the team members left, they carefully held their small compass in their palms one by one. If the baby is not good, if they encounter any stones, they should try it with enthusiasm to see if the pointer is shifted.

They had already fully understood its usage, and Ji Cheng gave them half a day to go back and figure it out on their own, and at the same time urgently deployed the Moonlight Wolf in the village.

We patched things together from various groups, and finally transferred 20 horses.

These moonlight wolves will follow the prospecting team to go prospecting everywhere, and will be responsible for detecting the magic essence that may be contained in the ore.

Xiaobai explained to the 20 wolves the task of sensing magic essence, and then asked them to stand by.

Ji Cheng watched the 20 wolves leave, patted Xiaobai on the head, and said earnestly:

"Find some more wives."

"what?"

"I see you are quite relaxed now."

Ji Cheng shrugged: The moonlight wolves in the village have been working for almost a month, and they are more proficient in the work they are responsible for. There are fewer and fewer people who need your wolf howling to direct, so... eat and drink enough It's all right, why don't you go find your wife? "

"Master, I found it at night..."

"Oh, work harder!"

At the beginning, Damu Village took the employment problem of Moonlight Wolf quite seriously, but now there is a shortage of everything, and soon it will not be enough.

Just like this time, if each prospecting member is equipped with a moonlight wolf for transportation, wouldn't the prospecting efficiency be greatly improved?

As long as sufficient supplies are prepared, one person and one wolf are a prospecting team.

Or there is a shortage of transportation. If there are enough moonlight wolves, Ji Cheng can vigorously develop the logistics industry in primitive society.

What a pity, what a pity...

But fortunately, wolves give birth to many litters, and the pregnancy period is also short. If the pups are handled properly, the cubs will not die young. There are seven pups in one litter, and 14 pups are born every year. It is not a joke.

The spring estrus is approaching, and the autumn estrus can also be expected.

Ji Cheng grabbed Xiaobai and told him to cast the net widely and sow more seeds, so that the blood of the wolf king should not be wasted. Then he formulated a plan for the moonlight wolf clan to have more children within one year, and gave preferential treatment and subsidies.

Preferential treatment and subsidy [-]: Female wolves will get maternity leave when they are pregnant until the time of childbirth, so they can give birth with peace of mind. The food they earn from daily work will not be reduced and will be distributed as usual.

Preferential treatment and subsidy [-]: The thermal insulation room for wolf cubs will be built, and the experienced members of the breeding team will ensure the healthy growth of each wolf pup as much as possible.

After explaining this, Ji Cheng drove Xiaobai to start a relationship.

That's right, love.

Since the Moonlight Wolves were able to communicate more frequently and directly, Ji Cheng and Xiaobai communicated and learned that the wolf clan will also develop emotional construction.

For example, the accident where the little white wolf howled to communicate with the moonlight wolf in the village was actually caused by the two wolves having a good chat and delaying work.

That is to say, fishing at work, being displeased by other wolves who ate dog food and making small reports.

This incident surprised Ji Cheng and made him think deeply.

The emotions of the moonlight wolf are now obviously moving closer to those of humans.

If it is about love, that is, falling in love with the other party, it is not completely controlled by physiology, but more factors come from the spirit, psychology, and are controlled by the heart.

Of course, Ji Cheng didn't like this kind of idealism.

He prefers scientific discussions.

Can magic element allow a race to undergo fundamental evolution?

From animals to intelligent creatures?

The answer is not yet clear, see later.

Thinking a little too much for a while, Ji Cheng withdrew his mind, and asked the communication room to send a message to the government hall, ordering the technical manufacturing team 1 to start manufacturing the second waterwheel after completing the recent work.

This waterwheel will serve the third-generation kiln and forge, with a higher upper temperature limit, in preparation for the smelting and forging of minerals collected in the future.

And when the prospecting team hadn't found the mineral in the early stage, Ji Cheng could also use it to make glass, which was then used to fulfill the promise of the thermal insulation room and unlock other glass-related technologies.

......

The next day, the prospecting and mining team, who had been familiar with the magnetic compass for half a day, left the mining personnel necessary to supply the village, and the rest were divided into 20 teams.

Each team is equipped with a moonlight wolf, with a full month's worth of supplies and comparison mineral samples, centered on Damu Village, and headed for the surrounding mines.

Half a month later, the second bucket-type waterwheel vehicle, the third-generation supporting kiln and forge were completed, and Ji Cheng plunged into the research and development of glass.

Glass is fused silicon dioxide, or silica, which is the main component of sand.

Damu Village adheres to Ji Cheng's good habit of never wasting anything, and there is a lot of sand sifted out when sifting clay in Damu Village.

So the material issue is not a concern, the issue is the melting point and other aspects.

The melting point of silica is 1700°C. Even the third-generation kiln has a hard time reaching this temperature, so the best way is to lower the melting point.

Add plant ash to the sand. When heated, the heat will dissolve grass alkali into the sand to lower the melting point. Then add some quicklime to this mass to improve the durability and corrosion resistance of the glass.

After one pass of operation, only repeated proportioning tests are left.Find the ideal ratio of silica, quicklime, and plant ash for glassmaking.

A few days later, after knowing the approximate proportions, Ji Cheng tried and tested again and again, and finally got the first piece of glass that he was satisfied with.

Write down the ratio, send it to the technical manufacturing group 2, and give them the task of making an incubator——

Glass and wood are used to build the supporting structure of the incubator, and leather is used to make hot water bottles, which are placed in the partition of the incubator.

Cover the incubator with a glass cover, so as to ensure that the cubs are breathing while reducing the complex air flow, air infection, turbulent flow, noise, and unnecessary disease vectors.

Generally speaking, there is nothing too technical about making an incubator. It is just a box made of new materials. After Ji Cheng gave a brief explanation, he returned to Shenju and met Xiaobai who came back to report today.

The spring breeze was proud of the wolf's hoof disease, Xiaobai ran over with his tail flicking, the wolf's face was happy, and the content of the wolf's mouth report was relatively simple and unpretentious:

"Master, I have two more girlfriends! Oh, I'm a little tired!"

"Oh, you've worked hard, and you've dated two more, so you've dated fifteen girlfriends at the same time, and the speed is really fast in more than half a month."

Ji Cheng roughly calculated: "Then if nothing happens, next year you will be the father of hundreds of children."

"Uh, there's nothing unexpected on my side."

Xiaobai was very confident in his wolf-like charm, blinked and said, "How is the wolf cub insulation room at the master's side?"

"Don't worry, the technology has already made a breakthrough. I just handed over to the technology manufacturing group 2 to start making incubators, but I still need to make a thermometer out of glass to complete all the technical projects."

"thermometer?"

"Well, it's a tool for measuring temperature."

Ji Cheng nodded and explained: "The body temperature of wolves is generally 38 to 39 degrees, and whether there is any change in the moonlight wolf will be measured in detail at that time.

Then after getting the specific temperature, hand the thermometer to the member of the breeding team who is in charge of managing the wolf cub insulation room, and she can observe the temperature of each incubator to ensure that the wolf cubs grow up healthily at the most suitable temperature, and the premature death rate will be greatly reduced. "

"So that's how it is!" Xiao Bai understood and was shocked.

He also predicted that he would be the father of hundreds of children, and he already had a sense of responsibility as a father in advance.

And the master cares so much about his child, it really touches the wolf!

Xiaobai felt a little bit tired before, and wagged his tail and said loudly: "Master, before the spring, I will work harder!"

"Uh, you are also moderate and do what you can."

Ji Chenglue blushed and patted the wolf's head: "Estimate yourself, don't be powerless at that time... If you talk about it, you have to be responsible for it, don't be a scumbag."

Chapter 193 Thermometer

, let go of that priestess

The full set of facilities in the wolf cub insulation room is short of a thermometer.

However, it is more difficult to make this thing than an incubator, which is why Ji Cheng put it in the later research and development.

At present, the glass of the incubator does not require too high precision thickness and transparency. It only needs to be roughly on a plane, then cut into regular glass surfaces, and then assembled with wooden structures.

But the shape and structure of the thermometer is a hollow tube with two glass bubbles and a scale. The difficulty of making it is straight up, and it requires a very fine craft-glass blowing.

Ji Cheng tried it himself, it was quite fun.

It's fun to blow, and even more fun to throw... He won't be doing it anyway.

After Xiaobai left, he asked the communication room to notify the technical manufacturing group 2, and transferred a team member with the most exquisite craftsmanship to go to the third-generation kiln together.

When they arrived at the place, Ji Cheng drew drawings and descriptions for the other party, explaining the required shape, and then handed over all the glass blowing to her, and went to tinker with mercury.

Among the minerals spit out by red lotus, there is cinnabar, and cinnabar can be used to extract mercury.

This bright red mineral is often found near hot springs and areas of historical volcanic activity.

So Liyan Mountain is not a real volcano, but Honglian should have been to a real volcano.

Uh, by the way, thinking of this, Ji Cheng suddenly slapped his head, and quickly used the communication magic to cast Honglian.

During this time, Honglian was practicing lightning magic in the backyard again. After receiving the communication, after listening to Ji Cheng's description and questions, she thought about it:

"It turns out that you call that place a volcano. I have indeed been there, but it is far away from here.

When I was looking for magic stones along the way, I found some in the cold area of ​​the north. After eating them, I continued to search, and finally landed in Liyan Mountain. "

"Ah, well..."
