Excellent tutor

Professor Liu took everyone ashore and walked to the pier for transporting ore.

"Zhang Gong! This is the way you envisioned transporting ore, what do you think?"

Wei Lai saw two huge barges parked in a waterway. A huge turntable was constantly rotating. It clamped the regular iron ore on the barges one by one and put them on a platform. On the platform were two huge turntables. The robot arm puts the ore blocks into a slide one by one.

Every ten seconds, a pendulum moves, and the ore blocks go into a deep black hole.

"The efficiency is not bad! Can we ship a lot this day?"

"Two hundred thousand tons of ore a day is no problem, not to reduce the impact on the existing iron ore market, but it will be much faster!"

"So many wow! Two hundred thousand tons! How scary?"

"Lailai! Our country imports more than 2 million tons of iron ore a day, which is nothing! Only one-tenth, not much at all"

"If so much is harvested in one day, how many years can it be harvested here?"

"Wei understands, don’t worry! The mines in this cave are not much less than those in the whole world combined. To put it simply! The ore exposed outside is enough for our country to last for hundreds of years."

"Wow! There are so many, this is really a treasure cave!"

"That is really a treasure cave, the ore here is easy to mine! good luck! Good practice! It is the best ore in the world! God bless China! No more worrying about others getting stuck."

The cruise ship arrived at the ore land that Zhang Chi visited last time. It

's much more lively here now.

There are bright lights everywhere, and various types of mining machines and special vehicles are constantly shuttling back and forth.

Fortunately! The lake in the mining area is illuminated by the lights They are all transparent.

It seems that mining pays more attention to environmental protection.

"Mr. Zhang, all the wastewater produced by mining here needs to be recycled.

It is not allowed to flow into the lake, and all wastewater generated from daily life must be recycled!

Although the lake is large, it has no sunlight and algae plants, and its self-cleaning ability is poor."

"Although the cost of water jet mining is higher, it makes less noise, less pollution, and is safer.

The key is that the mining operation is also simple! Easy to operate!

It’s just that the equipment wears out faster!

But it would be better if the waterjet equipment could be optimized!"

"Professor Liu! It's not impossible if you want me to do something, just give me another pack of stones from last time!"

"My Mr. Zhang! Last time I picked up two small stones on the ground to test, and the two people behind me kept staring at me!

You picked up such a big bag, and before leaving, you picked up a big one to play with.

I didn’t see them say anything!

All I have to do is help you carry your backpack!"

"That thing is inedible! You can’t drink it! Even if you have more women! That one pack should be enough, right?"

Professor Liu finally let out the suffocation he had been holding in his chest.

"hey-hey! This time half for one person!"

Professor Liu looked at the three people in the back row guiltily.

"don't want!"

"The water jet I designed was not what it looks like now! , the efficiency is more than 5 times higher, and the cost is reduced by at least 4 times, which is not only economical! And it’s very durable! At least ten times more durable."

Zhang Chi began to seduce Professor Liu!

Professor Liu believed that Zhang Chi did not lie to him!

"Just a small pack!"

"make a deal!"

The cruise ship arrived at the cave where the treasure was picked up last time!

It has changed a lot now.

There is a large iron gate at the entrance of the cave, and there are two guards. A guard on the ship and the guard at the cave entrance each entered Password, and then use their own keys to open the door. As soon as the door opens, the cave is brightly lit.

A transparent glass tunnel appears in front of you.

Walking along the tunnel for a while, it feels like you have entered the Dragon King's treasure house. A large number of gems of various colors are inlaid and scattered on the upper, lower, left and right sides of the glass tunnel.

Under the illumination of the light, a strange treasure light shines!

It seems that I have arrived at the treasure cave of the Dragon King of the East China Sea.

"Professor Liu, there didn’t seem to be so many at the beginning! I didn’t see any at the top either!"

"Of course there weren’t so many at the beginning, but some of them were cleaned out from under the ground and some were processed, so it’s what it looks like now!"

"Processed some! What's the meaning?"

"hey-hey! Processed gemstones are not uncommon on the market!"

"You mean those artificial jewelry?"

"Who can figure out whether it is true or false?"

"Have you really replaced everything?"

"Is there any? In addition to your pack, I took two more for testing.

Not one of the original trees is missing, they are all here! Just spread them out!"

"You asked me to check it myself! How do I know who is real and who is fake?"

"It depends on your vision and luck!"

"Not marked?"

"No matter how it is marked, I don’t know whether it is true or not. I won’t know until I take it out for testing!"

Zhang Chi knew that he had been fooled!

Professor Liu did not lie to him and agreed to let him check a pack and take it back.

But it was true and false! Although

Zhang Chi also has a detection method and guarantees 100% accuracy, he doesn't want to use it.!

There is no need to worry about these beautiful stones!

Just leave them here for everyone to enjoy!

It is better to enjoy them alone than to enjoy them all!

"forget it! If I dig out some trees, I have to trouble you to build some and refill them. It takes a lot of effort, but you still don’t know whether they are true or false? If I were to give someone a glass ball, my face would not be disgraced!"

"Zhang Gong’s ideological realm is completely different! It’s really worth learning! that is……"

"That's another matter. I don't want to check it. It's not that you don't give it!"

"Lailai! I promised you to pick up some rocks and take them back…"

"Brother Chi! The big bag of stones you picked up last time was put in the cupboard for no use. You can’t put it in the cupboard again if you pick up another bag! We won’t pick it up anymore!"

"Zhang Gong! Wei understands! In the geological exhibition room outside, there is a golden mountain, which is intended to be used as a treasure of the museum. It is more than 4 meters high, has strange shapes, is exquisite and porous, and is shining with gold. It will definitely be excellent as a decoration in the hall! Don't know…"

"Jinshan! real or fake?"

"Of course it is true, but the gold content is definitely not as pure as the 24K gold outside, but the main reason is that it has high ornamental value and artistic value!"

"Better than nothing! Something is better than nothing!"

"If you watch it, you will definitely not regret it! Now I regret changing this one."

"Will this treasure cave be open to the public in the future?"

"Not only this treasure cave, but also the Shambala Cave will also be partially open to the outside world. The gap where you released the drone last time has been renamed Tongtian Cave. In the future, we plan to build an elevator over 3,000 meters there, which will lead directly to the Tongtian Cave. to the Qinghai-Tibet Plateau.

Now the plateau and desert are really a natural and dangerous way."
