The mine cave is extremely dark without electricity supply.

When he went down to the depths of the mine, Fang Chong realized how troublesome it was to not bring lighting tools.

Fortunately, there are some "energy crystals" in the space. Under the prompt from "Maya", Fang Chong took them out as lighting tools.

The terrain of the mine is relatively flat, with an area of ​​about four meters wide and a height of about three meters...

"What is "special metal"?" Continue to move forward, without encountering any danger. Qin Lan asked Fang Chong and kept hearing Fang Chong say "special metal", but she didn't know what the "special metal" looks like.

"I haven't seen it either. I'll make the nose of the "Special Metal Detection Cat" light up later..." Fang Chong himself had never seen it, and hoped that it would just be placed on the "Special Metal Detection Cat"...

"Oh..." Qin Lan smiled bitterly. Fang Chong seemed too reckless to do this this time. What he didn't know was actually worth taking a risk?

The two continued to go down, and the area of ​​the iron ore cave was gradually increasing.

"Ding..."

Suddenly, a clearly visible sound attracted Fang Chong.

"It's lit?" Qin Lan also heard the red light on the nose of the "Special Metal Detection Cat" and exclaimed...

"Is there a "special metal" here?" Fang Chong asked a question in his heart. They are now at the bottom of the entire iron ore, and are about a hundred meters away from the bottom above the icon.

But because I discovered "special metal" in advance, I don't have to go to the end...

"Look, the "Special Metal Detection Cat" is walking over there..." Before Fang Chong could react, the "Special Metal Detection Cat" was already running forward happily, feeling like he discovered a new continent.

And behind, Qin Lan and Fang Chong had to follow him quickly...

"Beep, beep..." Continue to walk forward for less than twenty meters. The "Special Metal Detection Cat" stopped, and this time the small red light on the nose flashed constantly, and the sound also rang out in a series of sounds...

"Is there a "special metal" here?" Fang Chong took out a few relatively large energy crystals from the storage space.

Suddenly, the surrounding environment suddenly became much brighter, almost the same as the ground... You can also see clearly the place you chose for "Special Metal Cat" is the wall on one side of the mine...

Fang Chong looked at the wall of the mine while touching the head of the "Special Metal Detection Cat" to find out what the situation was...

The special metal detector cat has a small intelligent brain. Fang Chong touched its head and wanted to understand what the special metal detector cat's current reaction meant through the Mayan system...

"Super alloy hard iron..." Fang Chong's hand just put on the head of the special metal detector cat, Maya's voice sounded in his mind.

"Super alloy hard iron?" Fang Chong knew the name of the special metal of this name, but he didn't understand what it does.

"The density of super alloy hard iron is twenty times that of ordinary iron blocks, and the weight is also twenty times that of... Maya is used to explaining without Fang Chongwen.

"Twenty times?" Fang Chong was a little surprised. The density of iron was already high enough, but the super alloy hard iron was actually twenty times that of it. It was really incredible. No wonder it was called a special metal...

"This thing should be able to make some special weapons, right?" Fang Chong asked.

"Yes, super alloy hard iron should be able to break the defense of mutated creatures above level fifty..." Maya replied.

"Level 50, that's almost the same as an alien meteorite?" Fang Chong probably knew it.

It can break through the defense of about level 50, which is similar to the Qinglong Sword of the fifth commander last time. The Hulk is about level 50 defense...

"There isn't only one special metal, right?" Although it is quite good to be able to break through the level 50 defense, it is much stronger than ordinary metals on earth. At least this is the current technology...

But even now, there are more mutated creatures on Earth that are over 50 levels.

"Of course it is impossible. The special metals appearing in mines in different places are different. If you want more advanced special metals, you can also synthesise them.

For example, "super alloy hard iron" plus "liquid silver", and mixed with "red copper mother stone" is enough to break mutated creatures within level 200, and at the same time, it also has certain damage to the ordinary type of "Zak Clan"...

"Ordinary type of Zach?" Fang Chong has not heard Maya talk about "Zach". It was not that Fang Chong forgot it, but when he asked about "Maya" about "Zach", "Maya" looked confused. After Fang Chong failed several times, he could only give up temporarily..."

But Maya actually mentioned it himself today, so Fang Chong certainly needs to ask clearly.

The "Zakhs" can be said to be an eternal pain in his heart.

If the Zach tribe did not exist on Earth, he would not know how relaxed it would be now.

It is quite difficult to threaten him alone by zombies and mutant creatures...

"The Zach tribe is divided into many types, and they can continue to evolve and adapt to a creature of any environment and terrain. Moreover, the harsher environment evolves, the more terrifying the Zach tribe..." Maya's voice was very heavy.

"Can you determine their location now?" Fang Chong could feel from Maya's heavy words that the Zach tribe was really not simple.

However, not meeting a Zach tribe so far surprised Fang Chong...

At the same time, Fang Chong was still lucky in his heart, hoping that all the Zach tribes would die when they fell to the earth...

"If the level is not available, the system cannot find more information..." Maya replied.

"What can I do now is to improve my strength as much as possible..." Fang Chong also expected Maya's answer.

Although the information about the "Zakhs" is still in its primitive stage, Fang Chong still has a rough understanding of Maya's words just now.

The strength of the ordinary "Zak tribe" should be at level 200. Although its strength is terrifying, it can still be defeated.

But thinking of this, Fang Chong's scalp was also a little numb.

The ordinary "Zak" is at level 200, which is not scary, but what about the above?

There are "ordinary" and there are definitely "special", and there are many categories between "ordinary" and "special".

Fang Chong thinks there are at least three types: low-level, intermediate-level and advanced, right?
