Li Zhong walked along the way and took more than two hours to arrive at the Black Iron Mine.

It is still empty, with crystal-like ores everywhere, only scattered and special species growing here.

After Li Zhong passed through most of the mine, he came to the center of the mine. A cave stood here, which was the entrance to the mine.

Li Zhong took a deep breath, a trace of light flashed in his eyes. He held two rechargeable pistols in his hand, filled with crystal coins, and then entered the cave step by step and began to move towards the depths.

Along the way, Li Zhong encountered a fork in the road from time to time. Every time he reached a fork in the road, Li Zhong would use his former words - a man, write a sentence to ensure that his mark will not be repeated with other explorers, resulting in getting lost.

I don’t know how deep this mine is. Li Zhong encountered dozens of groups of crystal monsters along the way, but most of them were because of too many, and Li Zhong was not easy to start, so he only gained very little.

The black spirit flower that Li Zhong was looking for was an extremely rare treasure. He had also heard that it was said that it had almost disappeared in the human survival area, and it could still be found in the no-man's land outside.

In legend, the Black Spirit Flower can make people have the possibility of special evolution. Although it is only a weakened version, for most people, it is already a rare thing to encounter, which is enough to make ordinary people a real strong man and pave the way for the future.

Most of the true strong people among humans have special physiques, which are incredible. Almost all of the strongest twelve heavenly swords in humans have special physiques.

Li Zhong searched countless caves in the dark mine, but most of them were dead ends or the nests of crystal monsters, and there was no sign of black spirit flowers at all.

Li Zhong stopped at the end: "It's not a solution to continue like this. I have been searching for so long but haven't found it. It seems that this black spirit flower doesn't need to think about it. It's true that countless adventurers have searched here countless times but have not found it. I can't be lucky enough to find it. It seems that hunting the crystal monster is serious."

Thinking of this, Li Zhong said, "Forget it, no matter what, just keep your feet on the ground. Such luck-making things are not very suitable for me."

Li Zhong re-set his goal and began to hunt down crystal monsters in the cave.

Li Zhong appeared in the nest of each crystal monster. He walked eight steps under his feet to catch cicadas. His figure was as fast as lightning. His charging guns were shot in his hand, turning the crystal monsters into piles of gravels.

The core of crystal monsters was taken into his backpack by Li Zhong, and the milky white polymerized meat was also taken away. After some hard work, Li Zhong calculated in his mind that he had probably hunted the crystal monster worth 5,000 degrees of crystal coins now, and the two complete black-scaled beasts had about 7,000 degrees of crystal coins.

Li Zhong took a deep breath and said to himself: "It's quite fast to get money. Or just be a hunter. However, hunters have limitations. It's not a solution to rely on buying and selling dark beasts to obtain crystal coins and then purchasing potions to maintain various consumption. It's not a solution. You still need to be able to configure potions yourself to solve the consumption problem. Otherwise, the cost will be too high. I don't want to run around every day, so I don't have time to practice martial arts in peace."

At this time, Li Zhong was standing in a crystal monster nest and pondering. Li Zhong, who was standing among the corpses of crystal monsters, seemed particularly mysterious.

At this time, a wisp of water sounded into Li Zhong's ears. Li Zhong practiced martial arts, and the muscles and membranes of his body were connected together in the process of evolution. He felt that they were several times more sensitive than ordinary people. When he heard the sound of water, his face changed slightly and he thought to himself: "How could there be a sound of water here? Is it an underground river?"

At this time, a trace of inspiration flashed through Li Zhong's mind, "Yes, the underground river, there is an underground river here. Maybe the black spirit flower is where the underground river grows. No wonder there is no trace here."

When Li Zhong thought of all possible things, he immediately began to shake his ears and listened carefully to the direction of the underground river.

After a while, Li Zhong slowly moved his foot and quickly walked to a cave wall next to him. A huge crystal iron ore blocked Li Zhong's face. Li Zhong frowned slightly, and then took out a giant horn from his backpack, which was three feet long. This was something from the body of a giant bull-shaped dark beast. Although the level was very low, the giant horn was very hard. Li Zhong deliberately kept it.

Li Zhong held the three-foot-long giant horn and began to smash the hole wall with his arm. In an instant, pieces of fine crystal stones fell on the ground.

Crystals fell one by one, ding dong, and the sound of dong echoed throughout the cave.

As time passed, half an hour later, Li Zhong felt a lightening of his hand, and a hole appeared in front of him, and the half-meter-thick stone wall was dug through.

With a smile on Li Zhong's face, he immediately began to exert force and expanded the height of the cave.

Soon enough for a person to pass through appeared. Li Zhong put away his huge horns and stepped in one step. He stepped on a hard stone. There were bright lights around him. Fluorescent bacteria were everywhere. An underground river three meters wide appeared in front of Li Zhong. Countless fluorescent bacteria grew at the bottom of the river, and the river water was clear and clear.

Li Zhong was delighted and knew that he might have found the right place, so he immediately began to walk downstream along the river bank.

There are countless plants on both sides of the river bank, but most of them are dwarf fungi plants, and Li Zhong did not move because these plants are generally highly toxic, especially in this era.

Some of them were known to Li Zhong, and some of them had never seen them. Anyone who had never seen them before would never get close to them. Just walking, swaying and walking, after an hour, Li Zhong collected a lot of medicinal materials, all of which were valuable things. It was a great harvest. Li Zhong no longer worried that he would not have enough money. The various medicinal materials he collected were enough for Li Zhong to squander, worth at least 30,000 crystal coins. This was because Li Zhong did not conduct extinction collection.

When he arrived at the end of the river, a huge lake appeared in front of Li Zhong's eyes. The entire lake was bottomless. Various herbs were grown by the lake. One by one, familiar herb names appeared in Li Zhong's mind. Li Zhong, the black spirit flower alone, saw no less than three.

Li Zhong was shocked, but after a moment, Li Zhong immediately became alert. This place covered with countless herbs was too incredible, and there were probably something unusual in it.

Thinking of this, Li Zhong did not move rashly, but just hid quietly by the side and observed the surrounding scenes.

Li Zhong's eyes were sharp and he stared at everything around him for a quarter of an hour. Li Zhong's eyes suddenly shrank. He saw that on the ground of the herbs, there were some small insects densely covered with green bodies, which were very terrifying.
