Rongcheng is the largest city in the land of Sichuan and Shu, because the southwest is the border between Dafeng and Dali, here and Fujian, are directly under the jurisdiction of the imperial court, by a special governor is responsible for governance.

At the beginning, King Fu's henchman Chang Fulai, that is, the commander of the garrison in the land of Sichuan and Shu, after King Fu fled to this place, killed the original commander, occupied Rongcheng and secretly recruited troops, intending to make a comeback in the southwest.

It's just that a few days before he jumped, because the plan to capture the prince failed, he was dispatched by He Jin to attack the Yang family's army.

After the army conquered Rongcheng, although Yang Yunzhao led the men and horses to return to the court, for the stability of the land of Sichuan and Shu, before the arrival of the newly appointed governor and garrison commander of the imperial court;

His lieutenant general, Xu Liang, led more than 20,000 people and temporarily took over everything in Rongcheng.

In the few days that Liu Huayun was delayed on the way, the new governor Wang Ling and the government Yin Songkai had already taken office, and at the same time, he also brought over the holy decree that He Jin appointed Xu Liang as the commander of the garrison here, and his soldiers and horses were counted as the Sichuan and Shu garrison.

"Master Ma, Commander Gao, the lower officials have just arrived in Rongcheng, and they haven't had time to prepare for the branch newspaper, I hope you don't have to blame."

"Lord Wang, Lord Song, you don't need to be like this, Rongcheng is busy with all kinds of things, and some delays are understandable, how can I and the Holy Lord blame you."

Liu Huayun and Gao Cheng stayed in Xi'an for three days, visiting such as the Big Wild Goose Pagoda, Huaqing Pond, and Famen Temple...... and many other places of interest, after washing away the fatigue of the journey, they came to Rongcheng on horseback;

Along the way, you can see how tragic the battle was at the beginning, from the gates that were blasted open by Kamui cannons and the private houses that have not yet been renovated.

Therefore, when he saw the newly appointed and anxious Governor Wang Ling and Fu Yin Song Kai, how could he have any troubled thoughts.

"Brother Xu, in the future, the security of Rongcheng and the border will be due to you."

led people to repair the city gate and help resettle the people, naturally there was also a big man Xu Liang who was wearing civilian clothes but was covered in iron and blood, out of respect for Yang Jiajun, Liu Huayun wanted to talk to him.

"Brother Liu, I heard Dashuai say that you married the granddaughter of the old man, who is my Yang Jiajun's son-in-law; Don't worry, with Xu Liang in Rongcheng for a day, there will definitely be no accidents here......"

The original war lasted for nearly a month, and the people of Rongcheng were devastated by the war, and many buildings were basically abandoned.

After Liu Huayun arrived, it took two or three days to build a cement factory and a branch newspaper in the name of the imperial court;

After leaving the recipes for soap, soap, and candles to Song Kai, he took a team of Yang Jiajun dispatched by Xu Liang to the border between the two countries thousands of miles away under the protection of his son Xu Yunlong.

"Brother Liu, there are only two inns in this Limahe Town, but they are not very big, if they are all covered, they will barely be enough for us to live, you see......"

Following him from Rongcheng, it took nearly two days to arrive here today, and Xu Yunlong, who had finished inquiring about the news, came to Liu Huayun and asked with a light smile.

In fact, according to Xu Liang and Liu Huayun's original titles, Xu Yunlong called him his uncle when he set off, but the two were of the same age, and Xu Yunlong was not a few years younger than himself;

Therefore, Liu Huayun simply asked him to call himself the eldest brother like Chang Lang, which sounded more comfortable.

"Then it's all covered, let's go, Brother Yunlong, Brother Gao, let's put our bags in the inn, and after lunch for a while, we will go to the mountain over there to have a look......

Hey~~, wait, the color of this vessel is so familiar, is it made of nickel-copper alloy? ”

While speaking, Liu Huayun led the horses and walked towards the town under the guidance of Xu Yunlong;

Just as he was about to come to the Yunhe Inn, suddenly, he swept his eyes casually, and when he saw the white copper jar on a stall on the street, he immediately walked over excitedly.

"Uncle, do you like my copper pot? Only two taels of silver. ”

This is like a metal jar the size of an ordinary clay pot to carry it heavily, and while Liu Huayun was playing, a middle-aged man wearing a leather skirt with dust on his arms and face hurriedly walked out of the house;

It was not until this moment that everyone saw clearly that this was actually a blacksmith shop that smelted all kinds of agricultural tools, and the boss had a strong Yunnan accent, thinking that he had come from Dali.

Because Dali has always surrendered to Dafeng, the border between the two countries is not only not guarded by heavy troops, but also does not restrict the entry of the other party's people.

"Brother, I want this copper pot, but I'm curious, isn't all copper yellow? How do you make these colored copper cans, and can you show me the materials......"

When Liu Huayun first checked the information, he knew that in the Han Dynasty in 200 BC, some craftsmen had mastered the smelting technology of synthesizing white copper with copper, nickel and zinc.

He was not interested in the copper pot itself, but in where the strong man in the leather skirt in front of him collected the nickel iron, so he smiled faintly, took out two taels of silver from his arms, and asked while handing it to him.

"No problem, you see, the villain's ancestral craft is to fuse these two ores and brass......"

After receiving the silver, the strong man in the leather skirt immediately ran into the house with great joy, and walked out with a fist-sized piece of nickel iron and zinc without much effort.

This piece of ferronickel is silvery-white, at first glance I thought it was silver, obviously it is no longer the original ore, and the other gray piece is very easy to distinguish, it should be the finished zinc.

"Brother Liu, is this the metal you are looking for?"

Gao Cheng saw that after Liu Huayun took the ferronickel, he couldn't hide the excitement in his eyes, and he couldn't help but ask.

"Yes, this should be ferronickel smelted from nickel sulfide ore, which is exactly what I need, brother, where did you collect this ferronickel?"

Although Liu Huayun knew that the Limahe nickel mine had reserves of 2.7 million tons;

But at the same time, he also knew that the minerals hidden in the mountains after the founding of the People's Republic of China in the past life were not as easy to find as the surface laterite nickel ore in overseas countries such as Jinchuan in Gansu Province and the Philippines in the northwest border.

But as soon as he arrived in Limahe Town, he met a blacksmith who smelted alloy with nickel, copper and zinc.

"Yao~~~, it's on the mountain over there, if the official needs it, the villain can take you there."

He collects this kind of place called ferronickel by the other party, many of which can be easily mined, and it is not a rare thing at all; The strong man in the leather skirt saw that Liu Huayun was very bold and generous, so he pointed to the continuous mountains close to the big river not far away and said.

"Then there's Brother Lao, I don't know what you call it?"

That mountain range is dozens of miles longitudinal, and you can't see the edge at a glance, if you don't have a guide, don't say that you can find nickel ore in a short time, and if you don't get it, you will get lost in it, so Liu Huayun smiled faintly and said.
