The prehistoric demon forest...

The moonlit night like water is shrouded in the prehistoric demon forest. It is still as dangerous as ever. The demon forest in the night seems even more mysterious. In this case, few monks can practice in the demon forest deep in this situation.

Under the strong dead aura, a light and shadow quickly passed by the horizon. It was a golden light, which was so fast that even the middle-stage expert in foundation building might not be able to reach it, and he could not even see the essence of the golden light.

After passing through the dense forest, the golden light had been gone for a long time before it brought out a harsh sound of wind, blowing the branches and green leaves and falling.

The prehistoric demon forest is vast and has a territory of millions of miles. When Lu Chen was practicing in the prehistoric world, although it was divided into outer and deep areas, this depth was much smaller than the real prehistoric world.

The monsters that appear there are at the lowest stage of foundation building, and they go deeper into layers. Even in the foundation building, there are many monsters in the later stage.

According to the "Precious Ksitigarbha Map", the real depths of the prehistoric world are the territory of the golden elixir monsters. They do not enter the east and west sides of the prehistoric world, but only lie dormant in the deep forest.

Time passed slowly. Seven days later, Lu Chen's figure appeared in the depths of the prehistoric world, riding on the golden thread eagle, identifying the direction, and learning that this place was a very deep area in the prehistoric world, and that all the monsters below were in the foundation building and their later cultivation level was in the later stage.

Holding the "Princess of Ksitigarbha" in his hand, after looking around for a week, Lu Chen patted the back of the golden thread eagle. The brightly shiny golden thread eagle turned into a golden light and disappeared in an instant.

When it appeared again, Lu Chen came to a huge basin. It was said that it was a basin. There was still a hill several hundred feet high in the south. In the basin at the bottom of the mountain, there was a hollow area where there was no vegetation. It was bare. The moonlight was projected through the dense forest, and there was a faint blue and white light flashing.

To the south of this place is overgrown with weeds, and many precious medicinal materials are everywhere. Because this place is far away from the outer periphery of the prehistoric world, no one picks rare medicinal materials, it is also an excellent place for alchemy. The contrast between the two places can further show that the minerals here are extremely rich.

"It's here." Lu Chen's face was happy, and he stepped lightly under his feet, turning into a shadow and landing.

When you enter the basin, the scenery inside opens Lu Chen's eyes. The huge rocks everywhere are scattered in the basin, both big and small, forming together, like a natural array.

Among the huge rocks, there are shiny ores everywhere. They are embedded in the huge rocks. The mountains emit a faint white light. The white light will sometimes dim and appear as a blue dim color.

"The prehistoric Ksitigarbha Map is indeed right. There are earth crystal ore veins here. Now there are as many as a hundred earth crystals scattered on the surface of the earth, and there must be more underground." Lu Chen murmured to himself, his tone filled with joy.

Old Man Qi Jing also had his eyes lit up: "Let's just go here. Most of the monsters here are in the foundation building. In the later stage, they will not pose any threat to you. There are many earth crystals and can be used everywhere. It is an excellent treasure land for refining weapons."

Lu Chen nodded without looking sideways, took out a few of the top-grade spirit stones that had already been exchanged for in Lin Hongjin's hand, waved them around with a casual wave.

In an instant, a violent gust of wind blew in the middle of the basin. Lu Chen kept waving his hands, and a series of magic seals were successively cast out. The huge rocks were placed outside the basin as if he was driving them.

In a short while, a circular area with an area of ​​about 500 feet was cleaned out by Lu Chen.

After doing all this, Lu Chen seemed a little tired. This was the first time he set up a magic circle by himself. The hard work was no less than a battle with a late-stage expert in foundation building.

The gravel in the circular area was cleared out, forming a relatively empty space. The old man Qijing thought for a while and said, "I think you need to go back again."

Lu Chen was slightly stunned and asked, "Why?"

The old man replied: "You have never refined magic weapons, so naturally I don't know how difficult it is. It takes a long time to refine them and have experienced countless failures to get a skill that is easy to master. The ores here are all earth crystals. If you use this kind of thing to refine magic weapons at the beginning, not to mention the loss, even if you refine the low-grade magic weapons, some of them are due to the spiritual energy of earth crystals, and you cannot maximize your refining skills. Sit down low in everything, I suggest that you use tungsten gold and cold iron as the material, first refine the flying sword, and then use earth crystals after you are proficient~"

"So that's it." Lu Chen suddenly realized and said, "But no tungsten gold and cold iron ore veins were found in the prehistoric world. It will take at least three years to retreat this time. Where can I get so many ores for use?"

"Stupid." Old Man Qi Jing said: "Aren't you a disciple of the Immortal Alliance? Go there to buy them. Although these two things are very expensive, they are not rare. There must be one in the Immortal Alliance. Even if there is not, the Immortal Alliance's attention to you now will definitely satisfy your wishes."

"Well. How much does that need?" Lu Chen is still a beginner who has not even stepped up the threshold and has no idea how much material it needs.

The old man Qijing pondered for a moment and said, "Not much. In the early stage, you should first buy 100 tons of tungsten gold and one ton of cold iron, which is almost enough for you to use it for a while."

"How many? 100 tons of tungsten gold? And... one ton of cold iron?" Lu Chen was shocked after hearing this and almost sat on the ground without a single butt.

Tungsten gold, the price on the market is 5,000 low-grade spirit stones per ton, with a total value of 50 low-grade spirit stones; cold iron is 2 million per ton. The old man Qijing said a few words lightly, and the 2.5 million spirit stones are gone. This... there are too many.

Lu Chen was sad and said, "It's not that he didn't have 2.5 million low-grade spirit stones, but the spirit stones he had in his hand now were cheated from the Second Immortal Temple. 2.5 million was just emptying his pockets.

The old man Qi Jing was not surprised at all, but instead curled his lips and said, "Is this too much? It's too little. I have to use up all the things I said in less than three years. You need to buy them again. I guess, if you want to skillfully refine a low-grade magic weapon, at least you have to use all these materials. If you don't have enough, it's not enough."

"And (5), ore is not ore concentrate. You must be proficient in purifying ore concentrate. Only by extracting all the essences in the ore and melting all the impurities, so that the flying swords and even future magic weapons can be considered high-quality."

100 tons of tungsten gold...

1 ton of cold iron...

Lu Chen touched his Qiankun bag, and finally gritted his teeth, and a look of perseverance appeared on his face: "Okay, 100 tons is 100 tons..."

Lu Chen never wants to be chased again. In order to improve his strength, it is worth spending all the spirit stones.

When the old man Qi Jing saw Lu Chen gritting his teeth and decided to make a decision, he was quite amused and said, "Actually, you don't have to be like this. You can refine weapons. In the end, the flying sword you refined can be sold at the Immortal Alliance Auction House for a high price, and you may not be able to make a profit."

"Yeah, that's right." Lu Chen nodded, looked at the magic circle he had just set up, and said firmly: "First go back to the auction house to buy the ore back, and then go into seclusion."
