Thanks to the drunken eyes of Thousand Peaks, book friends 130129000512008 for their rewards...

Liu Buji did not look too excited, but instead said in a deep voice: "Order the troops to be on guard, be careful!"

Rong Li shouted ashamed. He had lived so old that he almost lost his vigor. Fortunately, he came back to his senses. So many good things are true.

But how could such a place that can use iron ore to build a city become a ruin? Will there be great dangers?

"I heard that a kind of insect appeared in the soil, raging everywhere, which was quite dangerous. Are those insects dried here?" Rong Li said hesitantly.

Liu Buyi felt aroused in his heart and asked, "Word, what kind of bug?"

Rong Li said: "I can't explain it clearly, either. I just heard some vague circulating..."

Xi Gao asked in surprise: "Why haven't I heard of the wind?"

Rong Li smiled complacently: "I am living such an old age and staying in Xiatu for three hundred years. Of course, the news is much more informative than you!"

Sure enough, paper cannot cover the fire. Is there any news now? Liu Buyi's heart moved and shook his head in a deep voice: "So you are talking about this legend, I know. But it's not made by those bugs!"

Rong Li nodded and said, "Yes, the legend of those insects has only been around for nearly a hundred years. Look at the ruins that have been ruined for hundreds of years!"

Liu Buyi nodded. He knew more than Rong Li. Those insects would swallow all resources and transform them into a continuous army of Zergs. If it were really done by those insects, the place would probably become nothing, with no soil and rock left. Where would these ores be left?

It’s just that Liu Buye is unwilling to say these things. After all, these things are still confidential for the time being. If they are spread, they will only cause panic.

Liu Buji sent troops to search the entire ruins. Unexpectedly, there was no other movement in this except for some wandering wild ghosts.

There is no expected danger at all, and it makes people feel lost in the face of one punch.

Until Rong Li came to a building in the ruins, he suddenly shouted: "I know who did this?"

Everyone looked at Rong Li. It was a tall building that seemed like three-story building. It was not like other parts of the city, built with ore.

But it was built with a kind of wood. When it was in its prime, it should be very majestic. But now half of it has collapsed, and some remaining wood has traces of burning.

"This is a gloomy wood. However, it is different from the gloomy wood in the mortal world. It is also an excellent material, even a hundred times more expensive and a hundred times stronger than these dark irons!"

He touched the burning traces, and a complicated expression flashed in his eyes: "This is the trace of the burning fire after the thunder struck. This is the battlefield ruins left by the Heavenly Court when he conquered the landfall!"

After hearing what Rong Li said, everyone suddenly realized that even Liu Buji was the same.

When the Heavenly Court was first built, it was ambitious. Naturally, it knew the importance of the Yin world of the Lower Earth. In addition, among the indigenous gods in the Xuanhuang world at that time, there were great gods from the Lower Earth resisting the rule of the Heavenly Court.

Therefore, the Heavenly Court sent a large army, and even many masters from the Taoist Sect in the Upper Realm, took action personally, entered the Lower Earth, and killed the ghost kings, great gods, ghost masters, etc. in succession in the Yin world.

However, this war also caused heavy losses to the Heavenly Court. At least Liu Buji knew that there was a real person in Yuanxu Temple who died in the battle in this place of the lower land.

If it were the traces left by the war back then, then everything would be reasonable!

Based on the time of this world, this war has passed a thousand years. It is impossible for real people to have any danger. This makes everyone breathe a sigh of relief.

"Since there is no danger, then let's do it." Liu Buyi said: "How to bring these dark iron ore back is also a difficult task!"

This time, their main purpose was to explore the way. They also had plans to find a small batch of bargains, but they never thought that such a huge wealth would be waiting for them.

Therefore, it is difficult to transport things back. Liu Buji was the first to think of Shenxiao Heavenly Palace, but even after the Shenxiao Heavenly Palace is upgraded, the storage capacity is limited.

However, these ores that are larger than humans do not have much weight. The dark world is different from the sun, and they are the precipitation of shadows. If these things are in the sun, they may weigh at least a few tons.

But in the dark world, these things are only a hundred kilograms. Even so, after all, they are too large and it is not easy to carry them!

In other words, if Liu Buye takes away ten pieces of this kind of stone, Liu Buye will be at most.

According to Duan Ning's estimate, these are rich ores, with an ore content of about half. In other words, the minerals brought back by Liu Buyi can extract 500 kilograms of Nether Iron.

What can such a little thing be considered? Comparing the mountains of ore accumulated here, thinking about it, I can only take ten yuan away. What is the difference between this and going back to the treasure mountain with empty hands?

"Master, it seems that we should set up a stronghold here." Rong Li said with a bright look: "Leave hundreds of troops to defend here, and we should decompose these ores here at will. We can even simply build this place into an iron-smelting base and directly refine the Nether Iron!"

"That's all!" Liu Buyi nodded. He suddenly realized that his thinking had entered a misunderstanding.

Now I am not a lone hero fighting alone, but a master of a big force. Many things do not require him to contribute, and so many subordinates are not in vain...

This place is about twenty days away from the Ghost Mansion. Of course, this is not a straight line, and it contains the time they waste all the way. So if you have to go all the way, you can take a trip in about seven to ten days, and it will only take more than twenty days to go back and forth.

I am barely within the controllable range, so I should manage it well. What I hate now is that I have too few slandering people!

Except for the two thousand ghost soldiers brought by Duan Ning, Liu Buyi's Ghost Mansion Xinli was not even two thousand. He originally thought it was a huge burden and was worried about supporting him. Now it seems that there are too few ghosts and there is no manpower to develop this huge ruin.

However, Liu Buyi immediately had an idea. Now that the upgrade of Shenxiao Heavenly Palace has been completed, he can sneak into the Tang Dynasty world without knowing it.

I don’t know how many ghosts I have gotten for myself, as well as military talismans I left there.

"Lord, there are a lot of gloomy trees in this city. Although some wastes, we can build large trucks, so the transportation volume will increase greatly!" Duan Ning gave an idea.

Even the elite ghost soldiers under him were already very powerful in the average control of ten kilograms of objects. Then two thousand ghost soldiers, one person, ten kilograms, but they could only take away 20,000 kilograms of ore.

Moreover, this is impossible. The key is that these ghost soldiers are equipped with armored weapons, weighing at least six or seven kilograms. In other words, they can take away less than ten thousand kilograms of ore back at most.

It's said it's a lot, but it's too inefficient to face this huge mineral deposit. Therefore, it's very necessary to build tools.

Liu Buyi asked, "Do you have anyone under your command who can build a big cart?"

Duan Ning said anger: "How can we miss all kinds of equipment to siege and defend the city in war? The last general happened to have a craftsman in the camp."

Liu Buyi smiled and said, "No, not bad. I see that your subordinates are so elite, I thought they were all war soldiers!"

When things were solved, everyone was excited. Since they wanted to build a big cart, they naturally couldn't leave immediately and had to set up camp.

Fortunately, there is a thick and tall city wall, so this matter is much simpler. In the soil, the cold wind often blows from time to time. The cold wind is like a steel knife, shaving the soul.

If it is alone in this kind of yin wind, it would be difficult for this kind of ghost soldier to control ten kilograms of objects. Even ghost generals who control hundreds of kilograms of objects will be difficult to bear.

Fortunately, the army formed a formation and the ghost energy condensed together to compete. Now that we have this thick city wall, it is even simpler.

Don’t look at the huge collapse of the city walls, but the city walls that are more than ten meters tall and four or five meters thick are simply no different from small hills. Camping at the foot of the city is enough to block the cold wind.

Liu Buyi's subordinates were all talents, and they were responsible for setting up camps. The others were responsible for breaking the stones and decomposing these large pieces of ore weighing one or two meters high for easy removal. Otherwise, they would not be able to handle them at all.

Duan Ning personally took his craftsman camp to collect gloomy woods and build a big cart. However, Liu Buji explained to Li Shimin: "I'll go out for a walk, if someone looks for me, you should know how to deal with it!"

Since Li Shimin entered the lower land, he became completely disappointed. His cultivation level was too low and he had no place to use his magic patterns. Liu Buji was willing to take him to his side, and the most important thing was to train him.

Liu doesn't even believe that Emperor Taizong of Tang will definitely become one of his subordinates, one of the best generals, or even a marshal-level figure in the future.

Although Li Shimin didn't know what Liu Buye was going to do, he understood it: "Don't worry, lord, I know how to deal with it!"

Liu nodded with confidence. If Li Shimin had no such ability, he would have recognized the wrong person.

"In theory, there should be more wild ghosts in this place!" Liu Buyi paused and said, "But now there are only a few hundred wild ghosts, which is unexpected!"

Li Shimin showed deep thoughts and walked along the way. He often encountered strong winds, like a knife.

This is not an exaggeration, but the strong wind of the earth is really as powerful as a knife.

A stone, a stone the size of a head, can be blown away in the gale of wind, and it will soon disintegrate, and it will be fine sand.
