Although the system is helping him less and less in his practice, it is still very powerful in terms of assistance.

Five or six minutes later, the system gave several methods to crack this space hybrid array.

Ling Li chose the simplest method of disguise and deception verification and passed these two protective formations to avoid alarming the enemy.

After entering the entrance of the cave, he judged that the passage deep into the underground should be an abandoned mining tunnel in the ancient ruins. After gradually moving down for a few minutes, the tunnel was no longer visible, and the surrounding area was pitch black.

Fortunately, this situation has little visual impact on Ling Li.

After moving along the tunnel for nearly a hundred meters, there was another protective formation in front of it.

Such strict protective measures can also show the degree of attention the cult elements attach to internal importance.

Through this protective formation, turn right and walk dozens of meters along an underground crack. Lingli enters a relatively open space. There are some artificial protective support in this space of about 100 square meters, but most of them have collapsed. There are two rusty and severely twisted railway lines on the ground. They should be the tracks for transporting ore trucks laid in the original tunnel.

In the dark passage, Ling Li continued to explore forward, walked forward for only a few dozen meters before stopping again.

In front of him, more than a dozen black entrances appeared.

Ling Li had no choice but to restrain his breathing, radiate his spiritual consciousness, and explore carefully along the channels...

Ling Li felt the breath in the passage and lasted for a while.

Most of the passages here have traces of people moving, and some of them have some residual odors. The activity time should be within one day. Among them, there is a main tunnel with broken orbits that have the most residual odors and are the most obvious. Someone walked by them not long ago.

Ling Li's eyes swept towards the dark main tunnel. The passage was obviously much wider and long. His spiritual sense could not detect the bottom. However, at first glance, the deep dark space was like the mouth of a monster who chose to eat people. Seeing this situation, his brows couldn't help but frown slightly.

This main channel should lead to the core part. The problem is that there are many crises inside. Obviously, the cult elements have been well harshly guarded and have made quite a lot of arrangements.

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

This is a very narrow and long inward shaft. Many places are collapsed and only one person can pass through. Ling Li walked inside and saw some narrow rock walls smooth. It was obviously cut out by weapons such as knives and axes when they were cleaned not long ago.

The situation here is similar to the situation in the ilmenite when Ling Li was in the trial in Boxyanggou, but it has to go deeper into the ground.

The tunnel was very long. In this dark and deep mining tunnel, Ling Li felt like he was going down the road, as if there was no end, gradually deepening the ground. As he went deeper and deeper in the tunnel, Ling Li noticed that the temperature in the tunnel was getting higher and higher, and even emitting a stream of hot air.

Ling Li noticed that there were traces and breaths left by some people in this tunnel. What was strange was that there were some traces of insects and reptiles. The footprints left by reptiles and insects were not particularly large, so it was estimated that the body size should be similar to that of the outside world.

As the source gas recovers, the size of organisms becomes larger and larger, which is mainly caused by changes in the energy consumption method. Before the catastrophe, the main energy of carbon-based life came from oxygen consumption. With the evolution of biological genes after the catastrophe, the main energy consumption of organisms is changing towards a nuclear substance similar to heavy oxygen.

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

Because of the short life cycle of insects, they evolved extremely rapidly after the source gas was recovered. With new energy as support, their body size became extremely huge. During the catastrophe, humans and even higher-level organisms suffered nearly extinct disasters, mainly due to insect plagues.

However, because they are low-level creatures, the body composition of insects and arthropods is destined to not have a huge body shape like vertebrates. Their bodies have too few muscles and their energy transfer efficiency are too low to support the energy consumption of larger sizes.

So, after higher-level vertebrates began to complete new evolutions, insects and arthropods once again slid towards the bottom of the food chain.

Even so, after the source energy revives, the mutant insects that first complete the evolution is still very terrifying.

Further forward, Ling Li found some round holes on the rock wall with a diameter of about one meter. These should be caves for insects or reptiles. The rock walls in the cave are very smooth, but no creatures are found inside. Some holes have traces of fighting, and perhaps these places have been cleaned up.

Although the beast control technique has methods to control insects or reptiles, these creatures have very low intelligence levels and can be raised according to their habits. In fact, it is difficult to fully control it, and they may be backfired.

The more you go, the more strange and unpredictable caves inside it are, it seems to be close to the situation of the female insect nest. Although the insects have undergone great mutation and evolution, some things inherited have not changed much. The structure of the insect ** part is probably similar, but it is much larger than in the past.

Ling Li called out Dan Tai Muye in advance.

There is nothing to do about this. If the opponent's cultivation is higher than his, especially in terms of the soul, he can instantly cut off the connection between him and the trial space. He and the trial space are maintained by mental power. If the mental power is imprisoned, it will be too late to operate it at that time.

Be prepared for any trouble.

Until the critical moment, Dan Tai Muye will not take action easily.

Ling Li and Dan Tai Muye walked through the winding tunnels one after another, with almost no light environment. For both of them, they had almost no impact. Their speed of traveling would not slow down because of this.

The only thing to be careful about is the dense insect holes on both sides.

There must be many alien insects inside that have not been cleaned up.

If you capsize in the gutter and get attacked by insects, it will really make Dan Tai Muye laugh at it.
