Chapter 558 Small Spiritual Vein

However, Cao Fang also knew that this was impossible, at least in the presence of Duke Guan, he really couldn't bring himself to deny the debt.

At that moment, Cao Fang endured the intense heartache in his heart, handed the Yin-Yang Fish Jade Pendant to Su Chen, and snorted coldly: "This time, you are lucky!"

After that, Cao Fang felt too embarrassed to stay here any longer, and said to Guan Fan: "Duke Guan, since you have already asked for someone else, I will leave first, goodbye!"

Having said that, Cao Fang bowed and was about to leave the carriage.

"Wait a minute, Master Cao." Guan Fan hurriedly called out, "Please don't leak the matter of the black iron ore!"

Cao Fang snorted coldly and said: "Of course, we have professional ethics, how could it be leaked?"

Having said that, Cao Fang jumped off the carriage and left.

Su Chen shook his head and said, "Duke Guan, it seems that I have caused you trouble."

Guan Fan smiled and said, "What's the trouble? Cao Fang is just an appraiser. The Guan family can afford to offend him. It's better for people like him to leave. Since Master Chen also knows how to identify black iron ore, I'll have to trouble Master Chen next."

"You're welcome, Duke Guan."

As he spoke, the carriage had already driven out of the imperial capital and headed towards a place outside the imperial capital.

After driving for a day and a night, the carriage stopped in front of a rocky hill.

This hill had no plants growing on it. It was bare, like a mound of earth.

At this moment, a circle of Guan family flags were planted around this hill, and many Guan family guards were stationed here.

Guan Fan and Su Chen got off the carriage. Guan Fan pointed at the hill and said to Su Chen: "Mr. Chen, this is the mine. There may be black iron ore in it."

"Master!"

The Guan family guards around saluted.

Soon, someone brought over a few ores in a tray: "Master, this is the ore mined from the mine."

Guan Fan took it and handed it to Su Chen: "Mr. Chen, please identify it."

Su Chen took one of the ores, scanned it with his soul power, and nodded: "It is indeed black iron ore."

Then, Su Chen identified the other ores and confirmed that they were all black iron ore.

At that moment, Guan Fan immediately showed a relaxed look, and the other people in the Guan family were also beaming with joy.

Even for a large family like the Guan family, the benefits brought by a black iron mine are extremely considerable. After all, a black iron mine is something that even the royal family would be jealous of.

"Mr. Chen, thank you for identifying the black iron ore for us this time. After this black iron ore mine is officially mined, please accept 10% of the income of this mine as a reward."

Guan Fan said to Su Chen.

Su Chen waved his hand: "Don't worry, although the ore mined from the mine is black iron ore, it is not certain how much black iron ore there is in the entire mine. If there are only a few pieces of black iron ore just now, it is not worth mining."

"Mr. Chen means that you want to go into the mine to investigate?" Guan Fan said in surprise.

Su Chen nodded: "I'll go in and take a look."

"Master, the mine has not yet dug out a passage, only a few caves have been dug, and it is impossible to go too deep, let alone detect what is inside the mountain." A leader of the Guan family came over and reported.

Su Chen laughed and said: "I have my own way to detect the situation inside the mountain."

As he said, Su Chen jumped up and entered the cave in a few steps.

Guan Fan looked at Su Chen's back thoughtfully. He didn't know how Su Chen could check the situation inside the mountain. Those caves were only dug outside the mountain, far from the inside of the mountain.

In the cave.

It was pitch black.

Su Chen opened the "Eye of Heaven" and scanned the surroundings, but found no other black iron ore.

He knew that black iron ore mainly existed inside the mountain, and the cave he was in was only on the outside of the mountain.

If you want to enter the mountain and check the situation inside the mountain, generally there is only one way, that is to dig a passage all the way to the depths of the mountain.

However, Su Chen obviously didn't have the time now.

He had a simpler method.

"Lu'er." Su Chen called secretly.

The Soul-Eating Gu Worm Ancestor heard this and immediately crawled out of Su Chen's arms and fell to the ground.

"Lu'er, send your soul-eating insects to explore the depths of the mine to see if there is any black iron ore in the depths of the mine."

Su Chen knew that many of the soul-eating insects on Lu'er were extremely small. When they gathered together, they looked like a ball of liquid, and the outline of each individual insect could not be seen at all.

Such tiny insects can often penetrate the gaps between stones.

Of course, this is also because Su Chen found that the stone of this mine is loose. If the stone is tight, the soul-eating insects may not be able to penetrate.
