"I have I have!" A migrant worker presented a bamboo tube.

Zhang Hao took the bamboo tube and pulled some crystal particles out of the rock into the bamboo tube; when he saw the surface of the water, a thin layer of ice quickly appeared and the bamboo tube began to cool.

"Saltstone!" said the migrant worker who just handed out the bamboo tube, curious and surprised.

"Do you know?" Zhang Hao asked, also curious about this migrant worker.

"I know, there are so many things. Langzhong in the country often uses this medicine. I didn't expect there are so many here!"

Zhang Han said: "Younger brother, this man is the one who reported the discovery of the dragon blood stone veins, called the white dragon fish. The surname is white, and the name is dragon fish."

White Arowana...Curious about her name, why don't you surname ‘Gold’ Well, in the eyes of the locals, this is a good name, a good name with regular rules. "White" means that the surname can't be changed; dragon fish means leaping dragon gate.

"White Arowana..." Zhang Hao pondered for a while, and asked while walking forward: "White Arowana, are you literate?"

"Of course, I am the teacher in the village. This time, the migrant workers in the four surrounding villages were led by me."

"Oh..." Zhang Hao turned to Bai Longyun in surprise, and nodded slowly. The name "White Dragon Fish" clearly surpasses the education level of ordinary villagers.

After pondering for a while, Zhang Hao suddenly said: "White Dragon Fish, do you think, what is the relationship between this dragon blood stone and saltpeter?"

Zhang Hao picked up a piece of semi-red and white ore. This ore is half a dragon stone and half a white saltpeter; there is a transition in the middle, and the red gradually fades.

Bailongyu looked at it for a while and said, "Master, I think this saltpeter is more like a dragon bloodstone changed after losing something.

This wind blows the sun, and the surface rocks are probably already... Well, the sea rocks are rotten... just like this clothes, after a long exposure, they will fade. "

"It's weathering!" Zhang Hao smiled, but looked at Bailongyu's eyes, but was full of amazement. This person has training value!

Compared with digging the wall, Zhang Hao hopes to train his own talents. Such a person, faithful.

"Weathered?" Bai Longyu frowned for a long time, and his face showed a bright smile: "This word is really good."

Zhang Hao looked at Bailongyu with a smile: "Do you really understand? If you don't understand it, don't slap it!"

"Uh...hey...Master wise..."

Zhang Hao squatted down to observe in a transition zone between dragon stone and saltpeter, and at the same time, he used his identification technique that was not very skilled.

Identification requires experience accumulation. Zhang Hao has only identified black iron before, and this is the first time that this dragon bloodstone has been identified. However, with the help of the different feelings of identification, it is possible to roughly judge some basic information.

This appraisal technique is more like a "true element's eyes" or "true element's tentacles". It uses true elements to detect the internal properties of matter.

This transition zone, whether it is dragon stone or saltpeter, contains a lot of gravel. After appraising for a while, Zhang Hao gradually added a shocking speculation in his heart:

This saltpeter and dragon blood stone should have the same "material" composition; but dragon blood stone has more energy! In other words, this dragon stone is a strange spirit!

The biggest difference between this world and another world is the existence of Reiki; and now it seems that Reiki is related to neutrons.

Does it mean that under certain circumstances, saltpetre can absorb Aura, and it seems to react with Aura-now it seems that Aura in Dragon Blood Stone and Aura in Spirit Stone are two distinct states.

Is it the relationship between combustible ice and ordinary ice? After the wind and the sun, and the dragon stone weathered, it became saltpeter again.

Zhang Hao tried hard to recall his little knowledge, but most of it was changed to the teacher: I only remember that the main elemental composition of saltpetre is nitrogen, oxygen, potassium or sodium, but in the state of minerals, there are often carbonates in saltpetre, etc. Impurities. No amount...well, I can’t remember.

But it doesn't matter. This time, it seems to have opened a brand new door for Zhang Hao. This world...it's interesting.

After probably determining the main components of the dragon blood stone, Zhang Hao was full of longing for the "new gunpowder". Just the power of the Dragon Blood Stone burst is so terrifying, if it is equipped properly...

Think of Zhang Hao excited.

Taking a deep breath, Zhang Hao calmed himself down and turned his head to look at the white dragon fish next to him: "White dragon fish, if you are appointed as the person in charge of this mine, dare you do it?"

"Ah..." Bailongyu was directly dizzy by the dizzy smash of the pie. He just followed Zhang Hao step by step, also a little thought, but did not expect the young master would ask.

But sometimes, some people just seize the opportunity, and the white dragon fish immediately swears to the sky and swears that they must defend it if they die.

Zhang Hao nodded: "It is not necessary to swear to defend, the ore is ultimately the ore, and it has to be effective after treatment. You only need to ensure the safety of the workers and strict management. Let everyone not chew their tongues and so on."

"Understand, the villain understands."

Zhang Hao looked at the white dragon fish, "Then you will gather all the migrant workers. Tell everyone that there will be five times the wages. But you need to sign a contract, at least 10 years.

And at the end of each year, different year-end awards will be issued according to their respective working conditions.

The year-end bonus is the most, and you can pay 12 months of extra money! "

"12 more months... that's two years..."

"Okay, you first let people look for the best-quality ore. Tell everyone that I will choose the 50-kilogram best-quality one. The one I selected will be rewarded per pound of ore-a piece of inferior spirit stone!"

"Ah..." Bailongyu opened his mouth in surprise. A piece of spirit stone is already a huge sum of money for ordinary people. Once, a spirit stone could be exchanged for one thousand black iron coins; and recently, a spirit stone could be exchanged for two thousand to two thousand five hundred black iron coins!

Under the reward...efficiency. But in a moment, more than 500 migrant workers all gathered in front of Zhang Hao.

The setting sun had already turned a little red, and it gave each migrant worker a layer of hope and excitement; the dragon stone in their hands was dazzling.

These carefully selected dragon blood stones are all pure and have the crystal state of the crystal column.

Zhang Hao turned his head to look at the white arowana holding the same piece of ore, and shook his head slightly: "White arowana, you come."

"Master." Bailongyu held the ore and ran over fartly.

"Baiyu, now give you a choice. Do you choose the ore or the deacon here?"

"Ah..." White Arowana was startled. Today his brain is a bit overloaded.

Zhang Hao looked at Bailongyu and stopped talking.

Bailongyu is worthy of being a teacher, and soon reacted, he dropped the ore to the ground. "Master, I see."

"It's about the same. Prepare to weigh and keep accounts."

Zhang Hao first walked around, looked at the ore of more than 500 people, and then started screening one by one. Zhang Hao picks and chooses only the best: the most crystal clear and the most perfect shape.

For every piece selected, Zhang Hao gave simple comments to convince everyone. Bailongyu don't know where to make a simple scale, which is not very accurate, but Bailongyu has also figured out Zhang Hao's mind at this time. It is not important whether the scale is accurate or not. This process is important.

And Bailongyu is a little smart, he chose the latest standard scale-decimal, rather than the traditional "half catty two" kind.

"Master, these twos."

"Um... less than a catty, send 600 black iron coins."

"Master, this is a catty."

"Send a spirit stone, plus 400 black iron coins."

"Master..."

The two came along and quickly selected 50 pounds of ore; of the more than 500 people, more than 150 were rewarded.

When Zhang Hao and Zhang Han returned to their homes, the lantern was already at the beginning of the first day. When they first met their father, Zhang Hao went to a beautiful courtyard to the west.

Entering the gate, Zhang Hao saw that Zhou Xueyao was quietly sorting out the books and materials brought from Xinglin Hall; the Zhangs gave Zhou Xueyao several maids to clean up.

Zhang Hao stood at the door, looking a little fascinated. Under the bright lights, Zhou Xueyao's serious and busy figure has an indescribable intellectual beauty.

A flowing black long hair and a plain white dress form a sharp contrast, quiet and soft...

and many more!

Zhou Xueyao turned suddenly, bright eyes staring at Zhang Hao fiercely. Suddenly his hands on his hips, Jiao Chi: "Come and help!"

Zhou Xueyao, who is busy, has quite a bit of majesty, what position to put the information on, and the commanding Zhang Hao round and round, and finally he sat down and let the maid beat the back, directing Zhang Hao busy.

Zhang Hao has a black line, but fortunately there are not many. When he was busy, he sat next to Zhou Xueyao and took out some beautiful dragon blood stones from the storage ring. "Xue Yao, found a mineral vein."

There was a little smile on Zhou Xueyao's face. After seeing the Dragon Blood Stone, it gradually disappeared.

Seeing this, Zhang Hao quickly drove the maid back.

Waiting for the maid to leave, Zhou Xueyao suddenly sighed, "Do you really want to study... this killing medicine?"

Looking at Zhou Xueyao's confused and painful eyes, Zhang Hao slowly got up and walked behind Zhou Xueyao and gently embraced her thin shoulder. "Xue Yao, this is not a killing medicine. This is also a medicine to save people."

The ancient medicine used to give people a strong body.

And now the explosives will give people a weapon against evil!

Actually, I was thinking that this practice is about saying "yin and yang". You look at the elixir and explosives..."

"Poof, I can pull it!" Zhou Xueyao burst into tears, only a little teardrop hung in the corner of his eyes.

"No, what I said is true." Zhang Hao looked serious.

Zhou Xueyao's face was a little ruddy, and some hurriedly got rid of Zhang Hao's claws to run. "Huh. Then I'll refine this dragon stone."

"Wait, Xueyao, I have an idea. Your previous method of refining dragon bloodstone with alchemy furnace may be wrong...cough...not the only way."

Zhou Xueyao akimbo again, exposing his own slender waist: "Okay, what else do you have?"

"That... I just have a vague idea. I want to use water to dissolve the ore, and then extract the essence of the ore like boiling sea salt."

"Can the stone dissolve?"

"If you try, you will know. Come, let's start now."
