When Shi Leiyin reached the boundary between the outermost layer and the second layer of the outer circle, he still remained attached to the body of the institutional species. Because of the effort to make the structure of the back electromagnetic cannon, Shi Leiyin did not make much progress in the devouring degree of the body of the mechanical species.

The only thing that can be said to have progressed is that now Shrayin doesn't need to remain in a state where the outer part of the body of the Institutional Species is completely surrounded by a layer of his own slime body. The devouring fusion of the shell has been completely completed - although the shell of the current mechanism species is still the same in structure and composition, it has been simulated and reproduced by Shi Leiyin's body. Under Shi Leiyin's conscious control, these shells can be used at any time to sharpen or prick, or even small electromagnetic cannons or the like.

The biggest advantage of completing the analysis of the shell is that Shi Leiyin can change more places to store those objects that have not had time to devour the fusion for the time being, such as the big thunder light worm that has been locked up in the shoulder warehouse so far.

In addition, there is the generation of spare biological warheads in advance. With enough space, Shi Leiyin produced a large number of biological warheads and stored them in the launch nest on both shoulders.

For this reason, the shoulders of the body have been doubled. Coupled with the two electromagnetic cannon barrels folded up on the back and the plasma launcher in the vest position, the balance of the body has been a little problematic. Although after Shi Leiyin increased the area of the soles of his feet and added a leg biological warhead launcher, there was no problem with the center of gravity. However, once you move too fast, there will be problems such as poor steering and uncontrolled acceleration.

It's just that Shi Leiyin, who has not yet fully mastered the body of the body, has no way to adjust the internal bone structure of this body, nor can he change the power system and balance system. For the time being, we can only move forward in this pattern that barely maintains balance.

There is a very clear dividing line between the second and first layers of the outer circle of the Stone Forest Secret Realm.

It's a structure that's very similar to the zoo's zoo enclosure. However, the scale is much larger, first a large depression about 50 meters wide and about 50 meters deep, like a moat separating the first layer from the second layer. The ground of the second layer is nearly 50 meters higher than the first floor, that is, except for a few connections, if you want to enter the second floor from the first floor, you must first descend 50 meters to reach the ground of the subsidence, and then climb the cliff with a vertical height of nearly 100 meters from the other end of the subsidence to reach the ground of the second layer.

In the subsidence, there are not only various poisonous insect creatures, but also a large number of rhizomes of those carnivorous plants in the first layer. Due to the scarcity of sunlight in the subsidence, the desire of the creatures to attack is even stronger, and under normal circumstances, adventurers do not choose to enter the second layer directly through the subsidence.

Some parts of the subsidence have passages called junctions, which are usually made up of several stone pillars. The pillar protrudes upwards directly from below the subsidence, creating an intermittent path that allows one to reach the second level of the ground by jumping at the flat top of the pillar. The distance between the pillars is narrow, and unless you are particularly athletic, even ordinary people can safely reach the opposite side through the connection point.

Shi Leiyin didn't get carried away and jump directly over the ground sink because he got the body of the mechanism that could perform a short air jump. Instead, when we reached the demarcation line, it took a little more time to find a connection point along the subsidence.

Perhaps due to the invasion of Dhaka's creatures, several of the stone pillars at this junction have been damaged, and most of the stone pillars have traces of attack similar to sharp claws, and even the top of one stone pillar has been completely cut off, which is obviously lower than the nearby stone pillars.

Stepping on the stone pillar to the second layer of the outer circle, Shi Leiyin released Magu and began to observe the situation around him.

The stone forests in the Stone Forest Secret Realm exist from the outer circle to the inner circle, but relatively speaking, the more inner the circle, the thicker and smaller the number of stone pillars.

If the spacing of the stone pillars on the first floor is equivalent to the deep mountain forest, the spacing of the stone pillars on the second floor is about the same as the campus grove.

Larger spacing between pillars meant easier movement for larger creatures, according to information Sheffield had sent through Magu. The Stone Forest Secret Realm has a large-scale creature equivalent to the lion tiger level since the second layer, and monsters have also been placed in it.

However, it is clear that due to the impact of the biological invasion in Dhaka, the second-layer ecosystem of the Stone Forest Secret Realm has been disturbed.

When he first stepped into the outermost part of the second floor, it was fine, but after only advancing less than a hundred meters, Shi Leiyin was already attacked by the three-headed blade-clawed beast.

This is a wolf-like quadruped at the top of the food chain in the second layer. With a body length of five meters and three bladed claws nearly thirty centimeters long on each of its two front paws, it can not only tear the shells of most of the creatures in the second layer, but even hard stone pillars can easily leave traces, hence the name of the blade-clawed beast.

However, this beast has a high ecological niche in the second layer, and usually lives near the third layer where there is more prey in the second layer, and a few live directly in the third layer. It is rare to see a presence at the boundary of the first and second floors.

And now Shi Leiyin has encountered three in succession, apparently because the Dhaka creatures have driven out the more powerful creatures in the inner layer, causing the ecological niche of the bladeclaw beast in the second layer to drop sharply, and it has to flee to the border to survive.

In line with the intention of not wasting energy, Shi Leiyin quickly transformed the fourth blade claw beast he encountered into his own energy storage, and then began to think about the way forward.

The body of the organism species is huge, and in the first layer, since the creatures in it are mainly small insects, even if they go on a rampage, there is no problem. Moreover, the dense stone forest structure also allows Shi Leiyin to avoid attacks from multiple directions - as long as he finds a gap and a card, he only needs to deal with attacks from both sides.

But not in the second layer, where the ecosystem is already in turmoil, can be attacked at any time by large or even super-large creatures from the third layer. And the frequency of the occurrence of Dhaka creatures is far beyond the level of a layer. On the first floor, only a few Blade Worms, a cannon fodder-level Dhaka creature, appeared, while on the second floor, although he still only encountered Blade Worms, Shi Leiyin saw an elite-level Blade Worm with a crimson body. The appearance of this elite Dhaka creature means that there is already at least one Dhaka lair in the second layer.

Although Shi Leiyin's mission is to scout the innermost layer of the Stone Forest Secret Realm, to find the specific location of the intelligent Dhaka creatures that have a high probability of existence. But that didn't stop Shrayin from destroying a small Dhaka hive. It could even be argued that if sapient Dhaka creatures do exist, doing so can also help confuse them. Let the other party think that Shi Leiyin is here to clean up the Dhaka hive, not to find his own traces.
