Although the system is now less and less helpful for his cultivation, it is still very powerful in terms of support.

After five or six minutes, the system gave several ways to crack this spatial mixed formation.

Ling Li chose the simplest method of camouflage and deception verification, and passed these two protective formations, so as not to startle the snake.

Upon entering the hole, he judged that the passage deep into the ground was an abandoned mining tunnel in the ancient ruins. After gradually moving down for a few minutes, there was no light in the tunnel**, and it was pitch black all around.

Fortunately, this situation does not have much visual impact on Ling Li.

After advancing nearly 100 meters along the tunnel, there was another protective formation in front.

Such strict protective measures can also show the degree to which cult members attach importance to the interior.

Through this protective formation, he turned to the right again, and walked dozens of meters along an underground crack, and Ling Li entered a relatively open space. In this space of about 100 square meters, there are some artificial protective supports, but most of them have collapsed, and there are still two rusty and twisted railway lines on the ground, which should be the original tunnel to transport ore and minecart tracks.

In the dark passage, Ling Li continued to explore, only a few dozen meters forward, and then stopped.

In front of him, there were more than a dozen dark passage entrances.

Ling Li also had no choice, so he had to restrain his breath, radiate his divine sense, and carefully explore along the various passages......

Ling Li felt the breath in the passage for a moment.

Most of the passages have traces of human activity, and there are several passages with some residual smells, and the time of activity should be within a day, among which there is a main tunnel with a broken and broken track, and the residual smell is the most and the most obvious, and someone has walked not long ago.

Ling Li's gaze swept towards the pitch-black main tunnel, this passage was obviously much wider and longer, his divine sense actually failed to detect the bottom, but at a glance, that deep pitch-black space was like a giant mouth of a monster that chose people to devour, seeing this situation, he couldn't help frowning slightly.

This main passage is supposed to lead to the core, but the problem is that there are many dangers inside, and it is obvious that those cultists are very well guarded and have made quite a lot of arrangements.

Ling Li thought about it, but chose a small pit not far from the main tunnel.

It is a steep inclined shaft, with a long and narrow interior, and in many places it is only allowed to pass through it due to collapse. Ling Li walked inside, and saw some narrow places where the rock walls were smooth, apparently cut out by someone with a knife and axe during the recent cleanup.

The situation in this is similar to the scene in the ilmenite when Ling Li was trying in Huangyanggou, but it has to go deeper into the ground.

The tunnel is very long, and in this dark and deep mining tunnel, Ling Li feels like it is all the way down, as if there is no end, gradually going deep into the ground. As he went deeper and deeper into the tunnel, Ling Li noticed that the temperature in the tunnel was getting higher and higher, and even emitted a blazing aura.

Ling Li noticed that there were some traces and breaths left by the passage of people in this tunnel, and strangely enough, there were also traces of insect and reptile activity. Reptiles and insects do not leave a particularly large footprint, so it is assumed that they should be about the same size as the outside world.

As the source qi recovers, the size of the creatures also increases, mainly due to the change in the way energy is consumed. Before the cataclysm, the main energy of carbon-based life came from the consumption of oxygen, and with the genetic evolution of organisms after the cataclysm, the main energy consumption of organisms is shifting towards a nuclear substance similar to heavy oxygen.

The energy contained in this energy substance is hundreds of times that of oxygen before, and it is more stable, which is also one of the reasons why the original thermal weapons with deflagration as the main kinetic energy cannot be used, and the energy of a bullet may be equivalent to a missile in the past, which is difficult to control at all.

Due to their short life cycles, insects evolve extremely rapidly after the resuscitation of source qi. Supported by new energies, they became extremely large, and during the cataclysm, humans and even high-level creatures suffered near-extinction disasters, mainly due to insect plagues.

However, because they are low-level creatures, insects and arthropods are not destined to have the same huge size as vertebrates, and their bodies have too few muscles and too low energy transfer efficiency to support the energy consumption of larger bodies.

So, as the higher vertebrates begin to complete their new evolution, insects and arthropods slide back down the food chain.

Even so, after the source qi was revived, the mutant insects that were the first to complete their evolution were still very terrifying.

Further on, Ling Li found some circular openings on the rock wall with a diameter of about one meter. These are supposed to be insect or reptile caves, and the rock walls of the cave are very smooth, but no creatures have been found in them. Some of the holes have some traces of battle, and perhaps they have been cleared.

Although there are methods to control insects or reptiles, the intelligence level of these creatures is very low, and they can be nurtured according to their habits, but it is actually difficult to completely control them, and if they don't do well, they will be counterattacked.

The further you go, the more eerie caves you have, the closer they seem to be in a mother's nest. Although insects have undergone great mutation and evolution, some inherited things have not changed much, and the structure of the insect ** part is also roughly similar, but it is much larger than in the past.

Ling Li summoned Yutai Muye out in advance.

There is no way to do this, if the opponent's cultivation is a cut above him, especially in terms of primordial spirit, he will be able to cut off the connection between him and the trial space in an instant. He and the trial space are maintained by spiritual power, and if the spiritual power is imprisoned, it will be too late to operate it at that time.

Be prepared.

Until the critical time, Tantai Makino will not make an easy move.

Ling Li and Yutai Muye walked through the winding tunnels one after the other, and there was hardly any light in the environment, which had little impact on the two of them, and their speed would not be slowed down because of this.

The only thing to be careful about is the dense worm nests on both sides.

There must still be a lot of insects in there that haven't been cleaned up.

If the boat capsizes in the gutter and is attacked by insects, it will really make Tantai Makino see the joke.
