Tian Hao did not stay in the Songshan territory, leaving Laudenu and others to help Zuo Lengchan collect food, and then took the family and women of the Songshan Sect to go upstream on a boat and return to the Huashan Sect.

Feiying had already sent a letter to explain the situation, and his master Yue Buqun had already sent someone to clean the empty rooms of the Huashan School.

After all, the Huashan Sect was rich in those days, with thousands of disciples and disciples, so they naturally owned many houses, which was more than enough to accommodate thousands of women, children and families of the Songshan Sect.

These women, children, Yue Buqun and others are naturally very welcome, and they are all full of potential stocks!

Moreover, most of these women had just died and happened to take advantage of the situation.

There is no way. There are too many bachelors in the Huashan Sect now. They urgently need qualified girls to practice the Sunflower Book and the Epiphyllum Book to speed up their practice.

It is time for these families, women and children from the Songshan School to come.

Even Yue Buqun was like Tian Hao, staring at Hengshan Sword Sect.

It would be a pity to let those girls be nuns and stay alone for life.

As for Ren Yingying, it is enough to repeat Shangguan Haitang's original treatment process, but the shackles were directly upgraded from Xuan Iron to Xuan Iron.

"The Hengshan Sword Sect can't be in a hurry."

After communicating with the cheap disciples, Yue Buqun understood that he had to slowly approach Hengshan Sword Sect, and according to the current situation, he could just let it go.

"It's true that we can't hurry, but we have to step up preparations, especially the construction of weapons. Haven't the iron ore veins in the Qinling Mountains been found yet?"

Nodding, Tian Hao asked about the investigation of the Qinling ore veins.

When he knew that Zhao Bulu and others were secretly rooted in the Qinling Mountains, he asked Zhao Bulu and others to inform the mountaineering people in the Qinling Mountains to search for mineral veins, especially those open-pit mineral veins.

Although a black tungsten ore was found at the bottom of Huashan Mountain, its reserves were very touching and the difficulty of mining was not low, and it was not even considered an ore vein.

It is naturally difficult to separate enough iron, at most it is only enough for Huashan School to use for its own use. They need a real iron ore vein.

Only with enough steel can you create enough weapons to prepare for war.

After all, you can’t go to fight against other alien cavalry without any hand!

"I found some ore, but I can't confirm it for the time being. You have to go and take a look."

Yue Buqun was also quite distressed about this. Although the invasion of the alien races in the grassland was a major disaster, it was also a great opportunity for their Huashan Sect if it was operated well.

At that time, the entire Guanzhong area can be directly occupied and Guanzhong will be transformed into their private territory of the Huashan Sect.

Then, with the Yellow River as the boundary, it is not a big problem to keep it.

However, this requires enough army and enough steel to build weapons and armor, but it is very difficult to find iron ore, not to mention that they cannot find it openly now, and can only place their targets in the vast Qinling Mountains, which undoubtedly increases the difficulty.

Moreover, if you want to build weapons in large quantities, you must not lose coal, and you cannot find that thing openly, so as not to attract the attention of the court.

"Take me to see."

After being shocked, Tian Hao decided to see if the stones brought back by everyone had iron ore.

There was a period of time in his previous life that he was interested in ore and found some pictures. If it really didn't work, he could take it to the laboratory for a slow inspection.

"Lava? How can there be lava in the Qinling Mountains?"

Soon after coming to the secret room where ore was stored, Tian Hao's eyes were attracted by a stone at the first time, he picked it up and observed it carefully, and confirmed that it was a piece of lava.

Although he had never seen this thing in his previous life, he had seen it many of it on Tianshan last time.

But the Qinling Mountains are geologically stable, so how can there be lava?

"That stone was found on a mountain 150 miles south of our Mount Hua. By the way, there is a small lake on that mountain."

Picking up a booklet and opening it, Yue Buqun found the corresponding page and explained.

"There is lava, and there is a small lake on the mountain. Could it be that there is also a volcano?"

Tian Hao thought something and had a bold idea.

"Master, let someone go to the mountain and dig down to see if the temperature is very high there. If the temperature is high, it will prove that it is a volcano.

Then we will dig a tunnel and we will use ice and fire jade to extract earth fire energy to make steel."

Generally speaking, coal can only be used as energy source when making steel. However, in this different world, the piece of ice and fire treasure jade obtained from Tianshan can extract earth fire energy, which is the most suitable thing to use to make steel.

Even coal is saved, and there is no flaw discovered.

Although Zhao Bulu and others wanted to dig out magma under Mount Hua as energy before, he did not think it could be successful.

Even though it is not clear whether this other world is still in a planetary form, the strata are undoubtedly thick, and it is too difficult and too dangerous to dig out the magma.

If there is a volcano, it will be much simpler, the underground magma there will be relatively shallower and the pressure will be much smaller.

Furthermore, they only need to dig up the level that can allow the ice and fire treasure jade to extract the earth fire energy, not really want to dig out the magma.

"I'll arrange this for a while."

Nodded, Yue Buqun recorded the matter.

"Millet tungsten ore? No, this part is not Millet tungsten ore."

Putting down the lava in his hand, Tian Hao continued to check the remaining stones and soon saw a special black tungsten ore.

This black tungsten ore is quite special. The real black tungsten ore accounts for only one-tenth of the tungsten ore, the remaining half is quartz, and the last four-tenth is another ore, which is closely connected to that part of the black tungsten ore, and even the black tungsten ore is wrapped in it.

"This was dug up at the bottom of our Huashan Mountain, which is much more than black tungsten ore."

Yue Buqun read the booklet in his hand and spoke.

"Is it manganese iron ore? It's a manganese iron ore vein below, and the black tungsten ore is just an accompanying mineral?"

As if he was thinking, Tian Hao probably guessed the composition of the ore vein at the bottom of Mount Hua.

"Dig, dig out all these black ores."

With a reminder, Tian Hao took the ore to do an experiment.

It is impossible to truly determine whether this thing is manganese ore by the naked eye alone, and chemical testing is required.

If it is really iron manganese ore, it will be developed.

This thing is much better than pure iron ore. It can be used directly to forge manganese steel, or even silicon manganese spring steel. It is quite good for forging weapons or armor.

In many short videos in my previous life, some great people bought large springs that cut into short sections forging knives.

It turns out that Tian Hao was lucky. After a series of chemical separations, it was finally confirmed that it was indeed manganese iron ore.

The content of ferromanganese is a little low, but it is also sufficient for smelting.

Now I'm about to go to the volcano to confirm, and then dig out a channel to make large steelmaking.

Of course, Tian Hao didn't need to be distracted from these things, so Yue Buqun and others handled them.

Even Zhao Bulu and others returned to the mountain villages in the Qinling Mountains again, and tens of thousands of people came to dig tunnels together, and the efficiency increased sharply.

Of course, these tens of thousands of people started digging from the volcano, after all, there is a Xichang station in the Huashan School.

Although people generally don’t come here, it is not easy to cover up if the noise is too big.

It is much easier to start construction directly from more than 100 miles away, at least the excavated rocks are easy to deal with.

Moreover, because it is a straight tunnel and the geology is hard, it can be used as a track by digging grooves on the ground in the tunnel. The rocks excavated with the black steel sword can be transported and exported directly, which is extremely efficient.

It can be dug dozens of feet a day, and it will only take more than a year to dig to Mount Hua. It is time to go.

The tens of thousands of mountain people gathered did not complain about this. On the one hand, it was because of the past kindness of Zhao Bulu and others, and on the other hand, it was because of too many sent by Huashan.

First, they promised that their children could join the Huashan Sect to study and learn martial arts, and then they promised that they would issue weapons, and even achieve the innate realm and could create magical weapons.

They are the long swords they use to dig holes now, like cutting stones and cutting mud. If they really have such a magic weapon, they can chop them up even if they encounter tigers and black bears in the mountains in the future.

Not to mention that the Huashan Sect also taught them that a sword function was used to swing the sword and dig holes, which could also strengthen the body.

Where can I find such a good thing?

With enough interests as inducement, everyone will naturally work hard.

Tian Hao, who was far away in the Huashan Sect, continued his own cultivation.

Cultivation and strength are the foundation of oneself, so he will naturally not forget this.

Moreover, his cultivation was at a critical moment, and the fusion progress of the yin and yang internal breath reached 2.5%, and he was marching towards 30%. That should be the fusion limit of the internal breath realm.

At the same time, the method of absorbing qi in the sun has also opened up a key point. As long as you work hard, you can create and improve it.

At that time, the absorption speed of the qi in the world can be increased and the cultivation can be accelerated.

It’s a pity that the tree wants to be quiet but the wind does not stop. Just as he is practicing with peace of mind, trouble or opportunity comes to him.
