The visitor was Zhang Zhengye, the second boss of the sand and gravel factory.
After hearing Liu Wei's answer, Zhang Zhengye nodded with a smile and said, "Don't panic now. We'll talk about it later in the night."
Liu Weilian claimed that it was, and also talked about Tang Songyuan's confrontation with him:
"I brought Xiaoyong here, but Xiao Tang, the excavator guy, didn't hand over the keys and said he had to call Mr. Xu..."
Zhang Zhengye frowned slightly and said, "How has Xiaoyong been studying during this time?"
Liu Wei patted his chest and replied with a smile: "I have studied with a famous master in Blue City for more than a month. There is no problem at all in this part of the sand factory."
"He has nothing to do at home. Although this job is a bit tiring, he earns more than 8,000 yuan a month, which is more money than most jobs in society."
Zhang Zhengye said: "Okay, I'll just call Lao Xu later."
"But you have to pay attention to me and don't affect the work of the gravel factory, otherwise... I won't be able to protect you!"
Liu Wei patted his chest again and promised, "Don't worry, my brother-in-law, there will definitely be no problems..."
Tang Songyuan returned to his dormitory, but secretly he had opened his perspective to observe Liu Wei's movements.
He could clearly see the process of Liu Wei carrying bags into the warehouse to put things away and chatting with Zhang Zhengye.
The living area of the gravel factory was not large, just within the fifty-meter range of Tang, Song and Yuan's clairvoyance powers.
Although he couldn't hear what the two were talking about, Tang Songyuan thought with his feet and knew that it must be something that was not very beneficial to him.
After watching the two of them leave after their conversation, Tang Songyuan focused his surveillance on the warehouse.
The warehouse is kept very neatly, and various mechanical parts or supplies are neatly placed on different shelves.
The only thing that caught Tang, Song and Yuan's attention was a small gas tank placed in the south corner of the warehouse, as well as a spray gun, measuring cups, crucibles and other utensils.
Next to these things, there is a locked cabinet.
Tang Songyuan had some guesses in his mind and focused his vision to look inward.
Ouch~!
Locked in the drawer of the cabinet were two pieces of yellow and golden dog-head gold ore!
There are two pieces, the big one weighs 6.7 kilograms, and the small one weighs 4.5 kilograms.
Really hammered!
Now Tang, Song and Yuan finally knew the reason why Liu Wei bought hydrochloric acid and nitric acid.
He wanted to mix hydrochloric acid with nitric acid to prepare aqua regia, and then use aqua regia to purify gold.
This sand and gravel factory not only produces various types of sand and river sand for construction, but also gold sand. This is no secret in the entire factory.
The excavator dug up all the sediment mixed with sand and gravel from the river bed, loaded it into the truck, and pulled it to a designated large funnel for unloading.
Then a spray gun with a large amount of water will be used to flush the sand and gravel.
The heavier pebbles are sent away by the conveyor belt and crushed into sand and other building materials. The lighter silt will pass through a downward sink together with the water.
A blanket is laid in the tank, and the gold sand that is heavier than river sand will be trapped by the blanket, and finally collected by a person trusted by the big boss.
Tang, Song and Yuan heard that two to three taels or even half a catty of gold sand could be collected in one day.
The upper reaches of the Yangtze River is the Jinsha River, and there are gold rush stories and legends in Blue City since ancient times.
But judging from the current situation, it is very likely that Zhang Zhengye and Liu Wei picked up these two pieces of gold nuggets privately and planned to swallow them alone.
Otherwise, Liu Wei would not secretly plan to prepare aqua regia to refine gold.
However, the secret plan of these two people was seen clearly by Tang Songyuan through clairvoyance.
With the weight and purity of these two pieces of nugget gold, at least ten kilograms of pure gold can be extracted. According to the current gold price, the value is as high as four to five million.
The profit of the sand and gravel factory is only three to four million a month, and this is only when the market is good.
Of course, this does not include the gold sand collected.
"Master Tang is at work!"
Soon it was time for the night shift, and the workers, who had almost rested, walked to their workstations one after another. Someone who passed by Tang Songyuan's dormitory called him by the way.
Tang Songyuan responded with a smile, turned off his perspective vision, and found a few bags to put in his clothes pockets.
Then walking around the living area, Tang Songyuan came to an awning where more than a dozen motorcycles were parked.
Taking out the keys and riding on one of the dilapidated motorcycles, he turned on the ignition and throttled the gas pedal. Tang Songyuan got on the motorcycle and rode straight to the excavator.
When the night shift started, it was completely dark. Tang Songyuan simply plucked up the courage, started the excavator and started digging towards the location where he found the gold nugget.
With his clairvoyant vision open, any movement within fifty meters could not escape his eyes.
People fifty meters away could not see his subtle movements at all, and would only think that he was digging sand.
In less than ten minutes, two trucks were loaded and sent away. Tang Songyuan had already dug out the entire location where the gold nugget was, and dug a huge deep pit in place.
If someone comes closer and shines a flashlight, they can see the dazzling golden color.
But all this was within Tang Songyuan's expectation. While the vehicle was returning, he dug down the bucket and easily dug out the piece of gold nugget that looked like a crouching tiger along with the sand around the ore.
The whole process took less than ten seconds, and there was no trace of sloppiness.
Sure enough, technology is the primary productive force.
Mining ore with an excavator is easy.
Tang, Song and Yuan were overjoyed and quickly folded the excavator bucket close to the cab.
Then he opened the door of the cab, jumped on the tracks, rushed over in a few steps, and held the gold ore in his hands.
Then he quickly returned and put the piece of ore into the small space behind the driver's seat without even looking carefully.
The lights of the truck coming from afar came on. Without any time to think about it, Tang Songyuan operated the excavator as if nothing had happened and began to prepare to load the truck.
Got rich~!
Tang Songyuan felt a burst of joy, excitement and wild excitement in his heart. He had picked up money, rice ears, and fish in the ditch before, but this was the first time he had picked up gold ore.
Getting rich, Tang Songyuan thought with great joy.
If given a choice, how many people don’t want to be rich...
And this thing, just like those who pick up stones, belongs to whoever picks it up.
However, Tang Songyuan also knew that now was not the time to completely rest assured.
Until this nugget of gold ore is safely taken out of the sand factory by him, it is not considered safe.
It was twelve o'clock in the evening, and when it was time for midnight snacks, the workers also turned off their machines and walked towards the living area one after another.
Tang, Song and Yuan Dynasties first used prepared black plastic bags to wrap the gold nuggets tightly in layers, and then put them into a cloth bag.
After jumping off the excavator, there was no one around.
Tang Songyuan quickly used the key to open the storage box under the motorcycle seat, and then put the cloth bag containing the gold ore into the storage box.
He then breathed a sigh of relief, sat on his scooter and drove toward the living area with satisfaction.
