The city lord listened to Zhang Hao's suggestion and was silent for a while. A faint smile appeared on his sad face, like a ray of sunshine shining through the dark clouds, full of the radiance of hope.
He patted Zhang Hao's shoulder hard, "I suddenly understand why General Wu is optimistic about you. I will immediately pass on your suggestion to General Wu."
Of course, Zhang Hao had to be modest: "It's just an immature suggestion. If you want to truly implement it, you need an experienced person like the city lord."
"Haha..." The city lord laughed, but after a moment his face became serious again: "Zhang Hao, I have some news to tell you."
"What?" Zhang Hao's heart jumped.
"You are famous. Now everyone knows that you vomited blood after hearing about the princess. Some people even said that you fell into a coma after vomiting blood."
Zhang Hao:......
Zhang Hao's face was dark until he left the city lord's palace. Who is so gossipy? How could such information be spread all over the streets? No wonder when I first entered the city, the people along the way looked at me so strangely.
Woolen cloth.
From now on, this kind of thing will not be shameful and will be everywhere on the streets~~~
Zhang Hao and Zhu Yuantang returned to the guild together. Zhu Yuantang will come to negotiate on behalf of the city lord's palace. The results of the preliminary negotiations will be submitted to the emperor's court.
The Zhang family already had mature credit terms, and Zhu Yuantang himself participated in the discussion, and new credit terms were quickly drafted. The main purpose was to add tax mortgage terms.
Before getting the emperor's reply, he could only draft it. Then Zhang Hao hurried back to his family. There were still too many things to be busy with at home.
The situation is so critical, Zhang Hao must strengthen the Zhang family as soon as possible. To put it bluntly, as long as the Zhang family is strong enough, even if the country of Qixia is destroyed, the Zhang family can still fight with the country of Taihua or the country of Canglan.
Negotiate terms and continue to survive.
Since the beginning of the country, the Qixia Country has gone through several changes. However, there are a few families and sects that have remained prosperous.
For example, the Ouyang family where the prime minister belongs, no matter how the dynasty changes, their support is indispensable in the new country.
This is the power of the family, a power that is completely different from that of the country.
Even if the emperor hates the Ouyang family, Jiuyang Sect and other existences, he still has to smile.
In this world of spiritual practice, it is said that "family, country, and world" means family first, then country. This order is not wrong.
Zhou Jue hadn't left yet, and when Zhang Hao came back, Zhang Shengde was discussing cultivation issues with Zhou Jue. Compared to the knowledgeable Zhou Jue, Zhang Shengde could only ask for advice.
Zhou Jue himself is the young master of Xinglin Hall and the chief disciple of Jiuyang Sect. The words "family origins" are no longer enough to describe him. But Zhang Shengde was born in Yeluzi.
Zhou Jue talked and laughed happily, but he kept no secrets. Except when it came to the sect and the core of the family, he actually knew everything and talked about it.
Zhang Hao came over to pay a visit and then hurried back to the smelting base.
Zhang Hao had a vague understanding of Zhou Jue's thoughts: by talking about spiritual practice, he would not lose anything to Zhou Jue, but he could win over the Zhang family.
Just Zhang Hao's status as a registered disciple of the Xuan Zhen Sect is no small matter. What's more, the Zhang family's Xuan Iron smelting ability is enough to put a smile on Zhou Jue's face.
If the Zhang family wants to truly climb the high branch of Zhou Jue, the best way is to produce high-purity black iron.
In communication between families, interests come first.
When Zhang Hao arrived at the simple research room, he was surprised to find that Huang Mingshan and others were already testing quicklime water.
Seeing Zhang Hao, Huang Mingshan shouted excitedly: "Master, we found that the volume of the burned air reduced by about a quarter after injecting quicklime water."
In other words, the oxygen content of the air in this world is around 25%?
Zhang Hao read the experiments conducted by Huang Mingshan and others. The beakers and others were made of translucent quartz stone. Glass... There is no glass yet, and Zhang Hao doesn't want to produce glass now.
When the Zhang family is truly stable and can fully protect its wealth, it will not be too late to produce glass. Now that we have quartz, it is enough for experiments. Anyway, there are specially polished magic tools and spells, so it is not troublesome to polish these tools.
Under Zhang Hao's supervision, Huang Mingshan conducted another experiment.
The upper layer of the flask is directly sealed with a small spell, and then a piece of hot charcoal is inserted. After waiting for a long time to confirm that the charcoal has not changed, place the flask in lime water.
You can see the limewater rising little by little, finally occupying about a quarter of the volume.
And the lime water also becomes turbid.
This is a very simple experiment, but this simple experiment can open the door to chemistry.
Zhang Hao didn't say anything, but picked up a quartz tube with a central opening and blew it into the lime water. He saw that the lime water also began to become turbid.
"This..." Huang Mingshan and others were surprised.
Zhang Hao smiled: "I have been wondering whether there are reactions similar to combustion in our bodies? Well, we will discuss this issue later. What we need to do now is to obtain high-purity black iron.
Let’s do an in-depth experiment. What will happen if we insert a red-hot iron bar into a flask?”
At the beginning of the test, obvious rust appeared on the surface of the iron bar, and the seal on the bottle mouth began to dent.
Until the iron rod no longer changes, place the flask upside down in lime water.
This time, the lime water instantly rose to a quarter position, and the lime water did not become turbid.
Huang Mingshan thoughtfully said: "There is a certain component in the air that can burn with charcoal and also make iron rust. Combustion with charcoal produces a certain amount of gas that can make lime water turbid. After reacting with iron
, solid rust is formed, and this part of the gas disappears directly.
And it seems that what we need to breathe is this part of the gas.”
Zhang Hao nodded with a smile.
Huang Mingshan was encouraged and thought thoughtfully: "Could this be the aura between heaven and earth?"
"Pfft..." Zhang Hao spit out a mouthful of tea. This was such a big turn.
Huang Mingshan felt a little embarrassed: "Master, isn't it spiritual energy?"
Zhang Hao covered his head, "If this is spiritual energy, then why do we add spiritual stone powder when we smelt black iron!"
"Oh oh oh..." Huang Mingshan also realized his mistake.
Chen Feng next to him suddenly said: "Is it the legendary life force?"
"The power of life can make iron rust?!" Zhang Hao rolled his eyes, but patiently let everyone think.
This is the process of breaking out of the cocoon, and this process cannot be encouraged.
But Liu Ming next to him jumped up: "I know, this is burning element!"
Zhang Hao continued to shake his head: "If this is combustion element, then what is the gas with light blue flame that we produced by calcining the charcoal before?"
Huang Mingshan scratched his head and suddenly asked Zhang Hao: "Master, do you know?"
Zhang Hao chuckled, but his words were decisive: "I don't know!
But I know that your speculation is wrong, because there are other explanations.
There is only one truth, and there is only one answer.
