When you're in the trees, just keep an eye out for flying bugs that make loud buzzing noises from patrols, and long-legged giant spiders that have long legs taller than trees and often roam the forest.

Lin Ning is not blindly evading, she is observing. For the past two days, she has been staring at a flying patrol, and has figured out their habitat, on top of a mountain cliff.

Yesterday, a new adult came to this patrol, and Lin Ning planned to use this adult to find the base camp of the Zerg.

Seeing that it was time for the Flying Insect Patrol to pass through this area, Lin Ning found a tall tree on the path that the patrol must pass through, and hid his entire body in the canopy.

She used the word "hidden" spell to hide her figure, and used the word "water" spell to isolate her breath. The sense of smell of the zerg is very sensitive, and if they don't hide their breath, it's like putting themselves in front of their eyes openly, and they will inevitably be discovered.

Not long after, Lin Ning heard a rustle of flapping wings coming from the sky, and she looked out from the leaves quietly without moving, and saw a team of five cockroaches like baby elephants gradually flying towards the area where she was hiding.

Lin Ning's gaze locked on the flying insect at the end of the team. Its size is significantly smaller than the other flying insects in the group, and its carapace is lighter in color than the other flying insects, and it is not as oily and shiny.

The patrol flew closer and closer, and the tip of Lin Ning's nose could smell the fishy wind set off by their wings. On her fingertips, the mark-type spell she named "Biao" had already condensed.

At this moment, Lin Ning is like the most experienced hunter, hiding all his aura tightly, and waiting extremely patiently for his prey to fall into the trap.

Finally, the patrol team flew to the top of Lin Ning's head, and in the sky above her head, the whole team made a big turn, and the flying insect that was originally blocked at the back of the team was instantly exposed to Lin Ning's eyes!

Lin Ning's eyes narrowed, and the incantation on his fingertips suddenly flashed, turning into an undetectable streamer that sank into the body of the flying insect at the end of the team.

"Success!" Lin Ning said in his heart.

But her figure didn't move at all, and it wasn't until the team of flying insects disappeared into the sky that Lin Ning quietly withdrew from the top of the tree, passing like a gust of wind among the staggered branches.

Returning to one of the safe areas she had excavated in the past two days, Lin Ning spread her left hand. In the palm of her hand, the word "trace" mantra flowed and shone brightly.

The spell of the word "mark" and the spell of the word "trace" can be used together, the spell of the word "mark" can mark the things that Lin Ning wants to mark, and the word "trace" can trace the origin of the things that are marked.

For example, this time, Lin Ning used the "Mark" spell to mark the unique aura of the new flying insect, and then prepared to use the "Trace" spell to trace its journey before coming to this patrol.

Feeling the faint indication of the mantra of the word "trace" in his palm, Lin Ning did not delay any longer, and immediately unfolded the "Footwork of the Heavens and Stars", and accurately stepped on the branches swaying in the wind, and walked in the direction indicated by the incantation.

The "Su" spell can only be accurately tracked for two days, and after two days, its effect will be ineffective, and Lin Ning must hurry up in order to follow the guidance of the "Su" spell to find the underground lair of the Zerg.

Her pace grew faster and faster, and she finally took off into the air, speeding across the sky with the word "遁" under the cover of the "hidden" word spell.

Half a day later. She flew over most of the planet and finally found the entrance to the cockroach from the underworld to the overworld.

Looking at the dark tunnel with unknown mucus on the cave wall, Lin Ning's heart was full of disgust and rejection. In the end, he completely closed his five senses, and only paid attention to the way before he made up his mind to step into it.

This underground passage doesn't seem to be used often by the Zerg, because the tunnel is dug according to the standards of the Zerg, so Lin Ning is very easy to pass through, and he can even use the word "escape" spell to fly quickly in the tunnel without touching the ground.

Lin Ning flew in the tunnel for a long time, and finally heard the sound of Suosuo in front of her, she quickly stopped her figure, pressed her body against the cave wall, restrained her breath, and waited for the unknown creature to come closer.

A beetle slowly crawled at the other end of the tunnel, its dark eyes without light reflection, covered in armor, and from Lin Ning's point of view, it looked like a moving fortress.

After Lin Ning used the spell of the word "hidden", the whole person was invisible, of course, this invisibility also has a limit, and it will be seen through by people who are more than two realms higher than her.

She is now in the late stage of foundation building - that's right, Lin Ning broke through the late stage of foundation building shortly after entering the third level after going through the second level. Therefore, cultivators in the incarnation stage and above can see through her disguise.

As for the concealment of the "water" word spell, it will change according to Lin Ning's understanding and mastery of the "water" word spell. She hadn't encountered an opponent above the Jindan stage yet, and she couldn't verify the concealment ability of the "water" spell.

But at least in the Xuanyue Secret Realm, she hasn't met an opponent who can see through her hidden eyes.

The insect in front of me, because he has been underground for a long time, has degraded a lot, and he is basically blind. Zerg, who often live underground, basically rely on their breath to recognize their way, or communicate with each other. Therefore, the effect of stealth is much greater underground than stealth.

Sure enough, the giant insect that moved like a fortress didn't notice Lin Ning attached to the cave wall, and it staggered past Lin Ning's side.

Lin Ning secretly breathed a sigh of relief, came down from the cave wall, and unfolded the spell of the word "escape" to continue on his way.

The power of tracing the origin brought by "tracing" guides her back and forth through the staggered and intricate underground passages.

Lin Ning knew that she was in the right place, and she encountered more and more zergs along the way. There were Zerg like the giant beetles she had encountered before, and they usually acted alone.

There are also magnificent purple zergs with the lower body like a spider and the upper body like a praying mantis, each of which is only more than two people tall, and it is an extremely small type among the zergs. They always come in groups, a dozen of them acting together.

The mantra of the word "trace" shone more and more, and Lin Ning had to clench his palm tightly to cover the light that came out of his palm.

It also marks that she is getting closer and closer to her destination.

Along the way, Lin Ning also had a rough guess about the number of various species in the Zerg -

The smaller the size of the Zerg, the greater the number of Zerg, and the number of Flying Zerg should be the rarest in the entire Zerg, which is also very scarce for them.

When the mantra of the word "trace" was almost lit into a bright light, Lin Ning finally walked out of the long road and reached a vast underground space.

Lin Ning felt the light that suddenly lit up, and his eyes were a little uncomfortable for a while. After completely walking out of the passage and standing at the entrance of the passage and looking down, Lin Ning was instantly shocked by the majesty and magnificence of this underground kingdom.
