As Tang Mu continued to advance, Tang Mu found that the number of insects he encountered was increasing, the strength of a single insect was getting stronger and stronger, and the higher the rarity of insect mutations, which suddenly made Tang Mu cautious.

Judging from the distribution trend of the insects, Tang Mu guessed that when he entered this underground world from the teleportation light gate, he was likely to teleport to the periphery, and as he advanced, it was likely to be towards the core of the underground world, the depths, which can be seen from the fact that these insect divisions are becoming denser and stronger.

"Could it be that those teleportation light gates first entered this underground world, and they all teleported to the periphery?"

Tang Mu thought with some speculation in his heart, he was even more interested in the situation of this underground world, this underground world can be regarded as another world that is integrated with the earth, but it can also be regarded as the world in the earth.

This world looks like a beehive, the direction in which Tang Mu is moving looks very broad, but in fact it is like a huge channel, but this passage is too big, or in other words, the shape of this world itself is composed of huge passages and huge nodes.

"Gold Eater Bug, Metal Eater, Sharp Teeth, Able to Devour Everything, Special Rare Bug ......"

Soon, Tang Mu came to the first channel node, this is like a new world, in Tang Mu's opinion, it is not an exaggeration to say that it is a realm within the realm, in this node world, countless gold devouring insects are all over the node world.

Moreover, this node world is a world dominated by metal elements and supplemented by earth elements, in this world, Tang Mu sensed that this gold devouring insect is constantly devouring golden elements to grow, reproduce, and then devour each other, become stronger, grow again, and reproduce again,...... Repeating continuously, Tang Mu sensed that these gold-devouring insects were constantly getting stronger.

"In my estimation, the fourth catastrophe is the eighty-first year after the end of the world, and now it is the eighty-first year after the end of the world, and there is still one year before these zergs will really break out, and this year is actually the preparation time of human beings, but it is not the growth time of these insects."

Tang Mu felt a huge threat, with the reproduction and growth world of these gold devouring insects, it is estimated that after a year, the gold devouring insects here are not only the number, even if they are a single strength, they can reach a very high level, and at that time, they will definitely become one of the main forces attacking the human race.

Moreover, Tang Mu also sensed that as the gold devouring insect continued to devour the gold element of this world, and spit it out, a by-product of the earth element was born, making this world a world where the two elements of gold and earth coexisted.

And in this process, the earth element actually passed through the native gold, giving birth to more gold elements, so that the elements of this world produced a cycle, in the process of this cycle, the two elements of gold and earth continue to increase and strengthen, and this node world is also constantly getting bigger and stronger.

It seems that this world and the gold eater are in a symbiotic relationship, which suddenly made Tang Mu feel the magic of this underground world.

"This earth element is a kind of innate soil, called Nirvana soil, which is a precious innate territory needed to cultivate the innate spirit root, and it is also the best material for refining the earth element spirit treasure."

At this time, Tang Mu made a new discovery, those gold elements, there are many types, it looks very miscellaneous, there are innate iridium, congenital Gengjin, congenital Xin gold, congenital Taiyi fine gold, congenital bronze, congenital black iron, congenital gold...... and many other innate gold ore elements.

These elements are derived from Nirvana, which is a kind of magical soil, like Nirvana, which can transform and derive all kinds of innate gold elements, which is a kind of innate soil that is no worse than the interest soil.

Therefore, this node world, if human beings can occupy it, is definitely an important resource production world, and the resource production of this world, as long as this cycle is not destroyed, the gold and earth element resources of this world can be continuously generated.

It can be said that this node world is an automated factory for the production of natural innate metals and innate nirvana, as long as it is not exhausted and fishing, basically, it can continuously harvest the two innate materials of gold and earth.

Even, Tang Mu sensed that with the continuous development of this cycle of this world, this world is getting bigger, and the two innate elements of gold and earth produced by it are also constantly increasing.

"This underground world is not only a threat, but also an opportunity!"

Sensing the preciousness of the resources born in this node world, Tang Mu suddenly realized that the emergence of this underground world was the need for the birth of the fourth tribulation, but the calamity was accompanied by chance, and this underground world, along with the Zerg, appeared together with all kinds of resources, but it was the fate of human beings.

After all, the innate materials born in such a node world are definitely very precious, don't think that among human beings, there are a lot of chaotic spirit treasures at every turn, and there are a lot of chaotic materials and the like, and the chaos spirit treasures in Tang Mu's hands seem to be able to appear in batches.

But who is Tang Mu, he is the lord of the Flood Desolation Domain, the recognized human emperor of mankind, such an existence, with such resources, is nothing, but those low-level human beings, in fact, most of them have no treasures, and it is already good to be able to have the existence of innate spirit treasures.

Most ordinary people, if they want to get an innate spirit treasure, or accumulate enough money to buy an innate spirit treasure, it takes a long time to accumulate, so the innate spirit treasure is still very precious, at least on the earth, it is the mainstream.

Because of the innate spirit treasure, only when it reaches the seventh order, such a spirit treasure can not have much effect on it, below the seventh order, the innate spirit treasure is the most suitable treasure, and the spirit treasure above the chaos level cannot exert its power.

And the innate materials, that is, the refining of the acquired spirit treasure, and even the mainstream materials of the innate spirit treasure, especially after the natal magic weapon refining method was announced by Tang Mu, these innate materials have become more precious, and there are too many human beings.

If you can control such a world where innate materials can be born in a steady stream, it is definitely a huge opportunity, and it is also very useful for the development of the Flood Desolation Territory.

"I wonder if such a world can be controlled?"

Tang Mu began to sense, and soon, he found that such a node world had been integrated with the underground world, and it could be regarded as a blessed existence in the underground world, but it was relatively independent, and it was impossible to control it.

Therefore, in the world of this kind of production materials, if you want to get the innate materials inside, you can only get them by sending living beings to continuously enter here to harvest.
