Old Tom and Li Zhong quickly shuttled through the forest. Under the dim fluorescent light, the forest was also a bit gloomy and terrifying. On the one hand, Old Tom kept watching the positions of the two on the locator, and on the other hand, he kept observing the situation around him, which was very familiar.

Li Zhongze followed him, guarding Old Tom's back to avoid sneak attacks, and also learning Old Tom's experience.

At this time, a foot-long black shadow flashed from the corner of Li Zhong's eyes and rushed towards him.

Li Zhong's multi-functional saber flashed with a flash of light, and the bitter sword light instantly split the rushing shadow from head to toe in half.

The black shadow fell to the ground and twitched. Only then did Li Zhong see clearly that it was an eight-clawed spider, colorful all over. It was the best protective color in this forest covered by a faint colorful light.

At this time, Old Tom noticed the spider corpse at Li Zhong's feet and was shocked and said, "My God, this is the Black Death Star. This is the most poisonous poison in this jungle. One milligram can kill hundreds of people. Many people once really under its mouth, this is a good thing."

After saying that, Old Tom immediately took out a syringe from his backpack, and at the same time used a saber to dissect the spider, dig out the poison sac, and then sucked out the toxins in it.

After the poison was sucked dry, Old Tom packed the toxins with a test tube, put them in his backpack, turned toward Li Zhong and said, "Let's go, let's go to the iron mine first, there are iron mountain trees there, and collect our next medicinal materials."

Li Zhong and his two feet were not slow, and soon arrived at a black land. After they arrived here, the surrounding scenery changed. The ground was no longer soft soil, but a fast and hard crystal rock, full of desolate atmosphere.

Old Tom said to Li Zhong: "This should be an iron mine. Originally, it was a place to mine iron ore before the catastrophe. Later, due to the arrival of dark matter, the subway here changed and generated a kind of crystal iron, a substance that can be used for alchemy. There is an iron mountain tree growing on it. The iron mountain tree is made of black crystals. It is very magical, but it is a plant."

Old Tom took Li Zhong through the iron mine. The surroundings of this place were crystals, and hazy light reflected from the crystals, which was very gorgeous.

The two of them soon arrived at the depths of the iron mine, and then crystal trees appeared in front of them.

Old Tom continued to introduce: "This is the Iron Mountain Tree. It used to be a tree that grew on iron ore and contains a lot of iron. Now it has changed a lot. Its seeds contain a magical substance that can be used and can quickly replenish the body's energy."

Li Zhong nodded, and had a preliminary understanding of the iron mountain tree. Looking at the black crystal tree, a hint of curiosity flashed in his eyes.

The two of them came to the iron mountain tree, and the old Tom said to Li Zhong: "Okay, go and collect herbs. There is no danger here, it's very easy, but the next medicinal material is not that simple, so you have to take some danger."

Li Zhong came to the Tieshan Tree alone, stretched out his right hand and touched the surface of the Tieshan Tree. Suddenly, a cold feeling reached his body, a cold texture belonging to rock metal.

Li Zhong looked at the iron mountain tree that was ten meters high, shook his head, and then began to climb.

However, Li Zhong immediately discovered that the Tieshan Tree was very bright and it took a lot of effort to climb up.

A smile flashed across Li Zhong's mouth and he thought to himself: "It's better to use the gecko skills."

Li Zhong's body changed, as if he had transformed into a gecko. His muscles began to climb up in the shining Tieshan Shushan, but in the blink of an eye, he reached the peak.

Li Zhong gently climbed onto a branch, waved his hand and took off the seeds of round and rolling thorns, and threw them into the storage bag, and quickly picked hundreds of seeds.

After Li Zhong finished everything, he jumped gently from the branch and returned to Old Tom and said, "Old Tom's business is done, where are we going next."

Old Tom said to Li Zhong with a strange look on his face, "Boy Li Zhong, what is your strange climbing skill? Why did you climb up the Iron Mountain Tree so quickly? You must know that people with inexperienced cannot do it, so they climbed to the top of the Iron Mountain Tree in one go."

Li Zhong smiled slightly and said, "It's just a gecko kung fu, specially suitable for climbing dangerous places. However, this kung fu requires a high requirement. You must train your muscles to stretch and retract freely. It is not possible for ordinary people to use it. If you are interested, I can teach you, but it will take a year or two to lay a solid foundation."

Old Tom shook his head and said, "Forget it, old man, I am already very old, but I can't stand the tossing. I have my own way. Next, let's go to the mine in the iron mine."

Lee nodded and then walked towards the depths of the iron mine with old Tom.

The two soon arrived at the center of the iron mine, which was deserted and crowded. Apart from the light reflected by the crystal, there was no life to see, and only the iron mountain trees were around.

A moment later, a cave appeared in front of the two of them. Old Tom said to Li Zhong: "Boy Li Zhong, take the rechargeable gun. Now we are going to enter the mine, where our next target, the crystal monster."

"The crystal monster is not a simple monster. It is made of crystal iron on iron ore. Life is born after the evolution of a large number of bacteria. It is a polymerized life form and is difficult to deal with. Unless it is dug out its core, it is completely impossible to harm these monsters. The black warrior with combat power is comparable to that of level 15. You need to be extremely careful, and the rechargeable gun cannot kill you in one blow. You should pay special attention to this."

After explaining various precautions, Old Tom led the way ahead and led Li Zhong slowly towards the mine cave.

The mine cave is covered with various luminous bacteria and moss, and the reflection of crystals is very bright, but the visibility is still not more than tens of meters.

But the two of them arrived at a fork in the road for a dozen meters. Old Tom immediately took out his saber and drove it to mark the hole wall, so as not to get lost and be familiar with the road. It seemed that he had done it many times.

After the two of them quickly passed through five or six forks in a row, they came to a huge hole. Old Tom and Li Zhong did not walk out rashly, but hid on the edge of the exit and watched the scene in the hole.

When Li Zhong saw it, he was immediately shocked. He saw that there was a huge cave. More than a dozen tall crystal-like monsters walking in the cave, very leisurely. From time to time, he grabbed crystal iron ore and threw it into his mouth. After chewing it, the crystal patch was chewed into powder and swallowed it.
