Excellent tutor

Zhang Chi came out to rest for two days.

Accompanied by Professor Liu, we entered Shambala Cave again.

Xiaoya did not go in this time, but accompanied her aunt and drove a helicopter up to Kunlun Mountain.

The Kunlun Mountains are a barrier between Tibet and Xinjiang. It is also because of them that Tibetan water cannot flow into Xinjiang.

It's been two days since Zhang Chi came in, and there's no information at all! This makes Xiaoya very worried!

A message came through on my aunt's satellite phone.

Xiaoya's helicopter started again, flying towards a target in the hinterland of Tibet.

Under a completely uninhabited snow-capped mountain, although the scenery here was beautiful, Xiaoya saw a deep canyon from the helicopter. Although it was not wide, it was bottomless.

Xiaoya and her aunt found a leeward valley on the edge of the canyon and started having a picnic

"aunt! look."

A small drone slowly rose from the gap in the canyon.

It flew straight towards their picnic spot.

The drone stopped.

Xiaoya happily opened the belly of the aircraft, took out a box, and wrote a letter He took the letter received by Xiao Zheng and gave it to his aunt.

In order to coax Xiaoya not to follow him into the cave, Zhang Chi promised to give her a gift.

There was something wrapped in cloth under the letter, and the bag said"Xiaoya's gift" A few words.

Xiaoya took out the cloth bag. It seemed to be a pair of men's underwear, and it was Zhang Chi's. Xiaoya had just taken it off himself two days ago, so he was very familiar with it.

This Zhang Chi, what is it wrapped in underwear? He also said is a gift

"Wow! so beautiful!"

A sapphire as big as an adult's fist emits a faint blue light in the sun! Xiaoya's hands and half of his body are reflected in a mysterious blue.

Xiaoya puts the ice-clear sapphire on his face, and it feels cool. It's so slippery, I've long forgotten that it was wrapped in Zhang Chi's underwear

"cough!"

Xiao Ya glanced at her aunt guiltily, and saw that her aunt coughed and had no other reaction. She quickly picked up Zhang Chi's underwear from the ground, rewrapped it, and put it into the bottom of her backpack.

This underwear was to be taken home for washing. of

"Put away the gifts after receiving them!"

My aunt looked at the canyon below and seemed to be talking to herself.

"Aunt! Do you want to write a reply?"

"No, they will be out soon."

Zhang Chi really couldn't bear to come out!

This is a cave! It's completely the treasure house of the East China Sea Dragon Palace! There are so many gems! Blue, red, green, purple, yellow...

Zhang Chi didn't know which one was best, so he picked it up I picked up a lot of good-looking, bright and transparent ones.

They filled all the gaps in the backpack.

Fortunately, the backpack was relatively strong.

Professor Liu also picked up two trees. Seeing Zhang Chi stuffing them into the backpack, he also had some ideas. He looked back at the two trees. The guards, seeing him looking straight at him motionless, had no choice but to reluctantly leave.

One of the guards said to the other guard:

"Report to superiors, this needs to be sealed!"

This one is so round, colorful, shiny, so beautiful! Just right for Wei Lai!

This blue one is so beautiful, like a huge eyeball, and like a deep blue ocean.

This one is for Xiaoya.

It can't fit in the backpack. , all in the pockets of clothes.

By the way, I checked two more pleasing ones and gave them to Professor Wei. Didn't the two guards have any plans this time? They reluctantly left the Gemstone Cave.

They came to the place where they found yesterday. Under the gap of light, the leader of the guard was writing a letter, while Zhang Chi was looking for something to wrap the gems.

I don't know what the situation is outside, and it would be bad if I didn't wrap it up. It was really hard to find, and the only thing he could take off was his underwear.

The one who delivered the letter The drone set off.

In addition to the guard's letter, there were also Zhang Chi's underwear and the wrapped gems.

The colorful gems were a bit big!

Zhang Chi could only hold them in his hands.

The two guards didn't seem to see Zhang Chi throwing them up and down in the air for fun. gems……

"lead! We are about to go ashore, put it in your pocket! Be careful of falling into the water!"

The guard kindly reminded Zhang Chi.

The engineering 3D printer has arrived.

There are more than a dozen factory technicians accompanying him.

According to Zhang Chi's drawings, this is the first official trial of the new equipment made by the factory. The factory was worried and sent a A strong technical team.

On the left side of the hole, Zhang Chi pulled out a concentrator tube from the mobile concentrator truck and inserted it into the jack at the tail of the 3D printer.

The 3D engineering printer has a total of eight moving arms, just like A giant octopus.

Five of its arms have five small moving arms, just like the five fingers of a giant stretched out.

Under the operation of factory technicians, the 3D engineering printer stretched out eight more legs. It stretched out like a spider. In all directions, the 3D engineering printer was lifted into the air.

The 8 big arms and 5 little fingers of the 3D engineering printer all moved.

Two of the little fingers shot out two laser lines and irradiated the heads of the ground piles at the same time..

The manufacturer's master explained that this was to determine the accuracy.

A big arm that seemed to be equipped with an impact chisel started to move first.

The chisel on the big arm chisled the pile head.

The other three big arms each clamped a bundle of steel bars..

Oh! This is not an ordinary steel bar! It is a porcelain steel bar.

It is produced by the newly invented process equipment in the Huizi Nianzhang Factory. It will never embroider and has the toughness and strength of steel. It is more durable than ordinary steel bars. There are more.

The little fingers on the big arms cooperate with each other! They aim the heads of the porcelain steel bars at the newly chiseled ground pile steel bars.

Two more big arms with fingers come, starting from the spread fingers High-temperature concentrated light was emitted from various degrees.

The porcelain steel bars and the porcelain steel bars in the piles were quickly welded together.

At the same time, another arm suddenly stretched out a thinner porcelain steel bar, like a spiritual snake in the big porcelain steel bar. The steel bars move upstream.

The condensed light at the same time flashes continuously, welding the large and small porcelain steel bars into one.

While the porcelain steel bars are fixed and welded, five concentrated lights are emitted from the five fingertips of a big arm, heating the ground pile head.

Wait for the top of the ground pile head When the surface started to turn red, another five-finger spread out and shot out a flow of heated fine sand at high speed towards the top of the red ground pile.

A horizontal ground beam of 60cm wide and 80cm high was soon printed.

The ground beam It quickly extended to the other end.

At the same time, the other end also extended to the middle.

Half an hour later, an 18-meter-long ground beam was completed.

"Zhang Gong! This is the slowest speed to start, because it is debugging, and also to let you see the process clearly."

"Make a few more test beams and columns to check their strength and parameter indicators! Zhang

Chi turned around and asked Ren Gong next to him:

"How about this method and speed?"

Ren has not fully recovered from the shock.

There is no need to set up formwork! There is no need to tie steel bars! There is no need for concrete! As long as there is sand! And any kind of sand can be used!

The life of concrete depends on the service life of the steel bars inside. This Porcelain steel bars can be used for thousands of years. Houses built in this way are really impregnable!

The speed is so fast! This equipment is so powerful! The efficiency is so high! It doesn’t even use much labor!
