After coming out of the playground and saying goodbye to Cao Feng, Dabao returned to the meditation room and entered the soul space.

A few pieces of dark iron ore that were traded just now were placed by Dabao in a utility room dedicated to placing sundries.

Dabao's eyes locked on one of the fist-sized ores, and took it out alone, the true qi was instilled in the palm of his hand, Dabao suddenly exerted force, the ore was torn apart, and a white jade-like walnut-sized stone emerged from it.

When the stone is held in the palm of the hand, it gives people a feeling of numbness and electric shock.

"Sure enough, it's Lei Yuanshi." Dabao was pleasantly surprised.

Lei Yuan Stone, which contains an extremely rich aura of thunder and lightning, is usually only available in places where thunder and lightning haunt all year round, and is an indispensable cultivation resource for cultivating thunder exercises.

In the world of the Royal Beast, the Lei Yuan Stone is known as the Thunder Jade, which belongs to the seventh level of resources, and after the death of the soul chain master above the Thunder Attribute Saint level, its soul chain is fused with heaven and earth, and the Lei Yuan Stone may be born.

"It's a pity that I didn't know where I dug it from the stall owner, so maybe I can get more Lei Yuanshi." Dabao said secretly.

It was still early before dawn, and Dabao decided to take advantage of this time to cultivate the Thunder Body.

Dabao sat on the ground with the Lei Yuan stone plate in his hand, and the true qi in his body traveled according to the meridians of the thunder body, and when a week was completed, the true qi in the body instantly became agitated, including the meridians and bones of the five internal organs, all began to ache faintly, and the skin was even more electrified.

In this regard, the treasure on the first floor of the thunder body has long been indifferent.

At this time, the Lei Yuanshi in his hand was pulled by the true qi, and a trace of electricity was withdrawn from the Lei Yuanshi and absorbed by the great treasure.

Don't look at it as just a trace of thunder and lightning aura, but the true qi in the body seems to have been given a catalyst, the degree of restlessness has increased exponentially, Dabao's brows suddenly wrinkled, and all over his body, from the inside out, Dabao only felt a hot sting.

Dabao endured it with all his might and continued to cultivate.

In the blink of an eye, it was early in the morning.

Dabao, whose face was still twisted, ended his cultivation.

"The thunder and lightning aura contained in this thunder yuan stone is really strong, but the benefits are also visible to the naked eye, and now the second thunder and lightning clone in the body is about to take shape, and stepping into the second layer of the thunder body is just around the corner." Dabao exhaled a breath of turbid air and sighed.

Dabao estimated that if all this Lei Yuan Stone was absorbed, the thunder body might be able to reach the third layer.

After washing up, Dabao went to class.

In the blink of an eye, another few days passed.

Dabao squeezed out a period of time every day to cultivate the thunder body, and the thunder body successfully stepped into the third layer, and the thunder and lightning aura in the thunder yuan stone was also completely absorbed.

After the third layer of the thunder body, Dabao temporarily stopped cultivating the thunder body and concentrated on refining the weapon.

With the assistance of the Hui Ling Pill, Dabao became more and more proficient in refining, and the original short sword had been refined by Dabao, and Dabao had to choose some materials, rebuild a long sword, and start a new round of casting.

After class this day, Dabao was going to go to the research room to continue refining.

As soon as I got out of the classroom, I bumped into a person, who was the stall owner of the ghost market to exchange talismans.

"Hello classmate, I don't know if you have made amulets recently, how many I want to buy?" The stall owner asked.

"I'm sorry, I haven't made it lately." Dabao said that, he bypassed the stall owner and continued to walk out.

"Classmates, your talisman is simply amazing, it doesn't look like mechanical equipment, how do you do it, teach me?" The stall owner caught up and said.

"If you have a Space Stone and a Soul Stone, I can teach you." Dabao didn't stop.

The stall owner was directly choked by Dabao's words.

"In this way, don't you want to know where my dark iron ore came from, I can tell you that there is a vein of dark iron ore comparable to a god-level resource, and I will use this news to exchange the method of making the talisman, okay?" The stall owner said.

"It's a loss." Dabao Road.

"I'm fine."

"I mean, I lost."

If it is really as the stall owner said, he knows a vein of dark iron ore, then what kind of stall does he still have, what kind of talisman do he need, isn't it fragrant to mine directly?

"I'll give you a discount, I'll tell you where to dig the dark iron ore, you just give me a hundred talismans." The stall owner did not give up.

"I'm going to do an experiment, please don't follow me." Dabao was unmoved.

"A hundred is not good, fifty is fine, but it is really not possible to have thirty, twenty, or ten cards, right?"

"Deal." Dabao finally stopped and agreed.

"Huh, you agreed?" The stall owner didn't react for a moment.

"Tell me, where are you digging the ground?"

"Chang'an Park."

"Chang'an Park?" Dabao was stunned.

Chang'an Park is located on the street next to the Imperial Capital University, with mountains and rivers, and a beautiful environment, many nearby residents will go to the park for a walk in the early morning and dusk, and sometimes the school's young couples will also go there for a date.

Dabao didn't expect that the dark iron ore dug by the stall owner would come from there.

"You're lying to me, aren't you?" Dabao questioned.

"It's true, there is a bamboo hill in Chang'an Park, and I dug the ore from that hill." The stall owner affirmed.

"How did you find out that there was ore in the hill, and even if there was, the park would allow you to dig it?"

"I also contracted a gold-swallowing beast, which is very sensitive to metal minerals, once I went to the park with my girlfriend to play, and by chance found that the hill contained ores, I naturally did not dare to dig during the day, so I had to sneak at night."

The Gold Swallowing Beast, which looks about the same as a mouse, is a high-level bloodline beast pet, and has first-class burrowing skills. Other than that, typical foodies, and only interested in metals.

After listening to the stall owner's explanation, Dabao called him a good guy, dare to dig with your front foot, and sell it with your back foot, no wonder the ore you set up in the stall has a fresh earthy smell.

"I've told you hundreds of millions of secrets, you should give me the amulet." The stall owner said.

"Wait for me to verify, and if what you say is true, I'll give you the amulet." Dabao Road.

Dabao agreed to meet again in two hours, and then went straight to Chang'an Park.

Soon, Dabao came to the bamboo hill that the stall owner said, the hill is not big, it is the size of a basketball stadium, like a dirt slope, the hillside is full of bamboo, it is very dense.

With the help of his divine sense, Dabao first circled around the hill.

The stall owner really didn't lie, there is indeed dark iron ore inside this hill, but the distribution is irregular, one in the east and one in the west, and there are many tunnels among them, which seem to be dug by the stall owner's gold-swallowing beast.

Dabao is sure that there are no veins of dark iron ore in the mountains, which are small hills formed by the accumulation of soil dug up elsewhere, and most of the dark iron ore is accidentally mixed in.

The real location of the dark iron vein may have to ask the master who excavated the soil.

Dabao's current divine perception range is only twenty or thirty meters, and there is no way to explore the entire hill thoroughly, in order to avoid missing Lei Yuanshi, Dabao glanced left and right, and after confirming that there was no one nearby, he drilled towards the bamboo forest.

If you stand on the top of the mountain and don't perceive Lei Yuanshi, then there is really none.

Dabao drilled into the dense bamboo forest, constantly marching towards the top of the mountain, the bamboo is hard, straight and dense, it is really difficult to pass through it, Dabao complained: "This bamboo is too densely planted." ”

As soon as he finished complaining, Dabao suddenly stopped and looked at the mountain with a strange expression.
