The range of insect swarm activity is not limited to the insect hill. Below a few insect hills is a large-scale cave world. With the development of the Zerg for several years, the cave space has been expanded even more. There are at least hundreds of channels, criss-crossed, and groped one by one. Without a few days and nights, it is impossible to find out the bug's nest.

Because the worms are mostly very large, most of the passages are extremely wide, and they have good ventilation. Humans can not suffocate by moving inside the wormhole.

The rock walls of the cave are covered with luminous green slime, or wet moss with luminous ability, boulders or rock cracks are everywhere, easy to hide, and the exploration process is not difficult.

The three closely followed the nanny worm, probably not a fighting type of insect relationship. The nanny worm was slow to respond and had very low alertness. No trace was found from beginning to end. Two tanker-like nanny worms switched one after the other. After many passages, they finally entered a particularly huge underground tunnel.

"It's really nothing!"

This passage is about 12 meters long, wide and high, and the caves are obviously heavily guarded. There are combat insects every few tens of meters. In addition to the worms guarding the guards and the patrol team walking back and forth, when the nanny worm comes, immediately retreat Enter the caves on both sides of the passage and let the nanny go first.

Zhang Mu understood that it would not work to break into it directly. He looked around and said, "Let's climb up from above, be careful, don't make a sound!"

Zhang Mu walked to the rock wall on the left, and from a small pit, he took out some mucus and painted it all over. This mucus was a bit disgusting, but it could mask the smell and block the spread of body temperature. According to Zhang Mu's observation Most of the bugs don't have good vision, but they can lock their prey with sound and temperature.

Grab a piece of stalactite and start climbing. The stalactite has been eroded all year round and it is smooth. The three must be careful to make mistakes. There are too many bugs in this channel. In case they startle them, don't try to pass.

Fortunately, the human form is nothing in front of the giant worm. When covered with mucus, as long as it does not make too loud sounds, the giant worm will not notice a few people jumping around.

Zhang Mu avoided the patrolling bug soldiers, and finally came to the end of the passage. It was a huge hole. After entering, a new world appeared in front of the three.

This scene is too shocking. A huge underground space, at least three or four regular football fields, with about ten passages around.

It is not the size of the cave that is surprising, but the things that appear inside the cave.

The floor, the wall, and the denseness were all worm eggs. Visually inspected as many as five or six thousand!

These worm eggs are about the size of a washbasin, the surface is light green, and they are neatly arranged. They are divided into four areas. Each worm egg is managed by eight pink giant worms. They swim in the worm eggs. In the swarm, take care of each worm egg carefully. Whenever there are larvae broken eggs, they will bring out the larvaes in the past, and finally send them to the breeding room-the cave where Zhang Mu just went!

In the middle of the underground space, there is a towering tall mountain of meat. There are no creatures at all. There are more than a dozen black bodies all over the body.

Zhang Mu got closer, and finally found a pink giant worm that cares for the eggs.

More than a dozen giant worms that are black and hard with spines are called guardian worms.

[Guardian Bug] (Bronze Lord), Level 25 Bug Monster, Life 32000, Magic 11000, Attribute? ? ? ,skill? ? ? Introduction: The guard responsible for guarding the Zerg Queen is the most powerful warrior in the Zerg population.

As for the "Rose Mountain" in the middle, Zhang Mu didn't dare to approach it easily, although he didn't know what it was, it was just a mass of hundreds of tons of meat, which was wriggling like life, and it was disgusting just to be a protagonist. This is by no means a good thing. Zhang Mu approached carefully, using a high-level insight from afar.

"Strange, why is it a story monster?"

Zhang Mu was too surprised, and a reminder sounded in his mind.

"A new task is released, please pay attention to the taskbar"

New missions released!

Wang Ling said in a low voice, "What happened when we received a task?"

Zhang Mu has closed the task bar, closed his eyes slightly, and thought about it. It is not a hidden task, but an alternative world task. The so-called world task can be understood as a separate task in the secret world, which is the main line. It is not directly related to the main line. It is a character in the mysterious world. There is a word "underline task" that is better understood!

There are only three types of missions in the Killing Secret, which are mainline missions, side missions, and hidden missions.

The mainline task is compulsory. Failure to complete the mainline is considered a failure of the secret challenge and is severely punished.

Sideline missions are extra missions. They are missions that exist in the mysterious world. They are not directly related to the mainline. Whether completed or not will not affect the mainline, or it will only have a slight impact.

Hidden tasks, as the name suggests, are hidden tasks in the mainline. If the hidden story is completely triggered, the mainline tasks will change.

Side missions and hidden missions are generally not easy to trigger, and even some secret realms have no side missions or hidden plots.

Compared with the hidden task, the sideline task has a lot of looser conditions. Once the hidden story is triggered, it must be continued. After the sideline story is triggered, it is optional or not.

However, the side mission rewards are also generous, if they can be completed, Zhang Mu does not want to give up.

Zhang Mu told the two of the situation.

Scorpion said with a husky voice: "This is the core of the bug's nest. It is heavily guarded and crisis-prone. Even if we use the power of the barbarian, we may not be able to kill him, and we may still pay a bitter price for it. It is not worth it."

Zhang Mu did not give up, but just said, "Watch for a while before you talk."

The three found a rock crack and only one was allowed to enter. The worm could never enter, hiding in the crack. Even if the camouflage was not opened, the worm passed by nearby and found it unexpected.

Zhang Mu remembered the trajectory of the bug once he observed it: "It's a bit tricky!"

The worm can't move by itself, and its attributes are very weak. Only the spirit is strong, allowing it to control thousands of worms to die.

It is not difficult to judge that the power of the worm is not in itself. There are many high-level existences in this Zerg population, fully possessing the lord-level strength. The power of the post-worm is to dominate the entire clan, and the overall strength gathered is far stronger than a lone gold lord!

However, Zhang Mu has always believed in a constant truth, that is, in the killing secret, there can be no solution.

First, the post-worm intelligence is not too high.

Second, the swarm is fatally flawed.

The first point is easy to explain. If the worm has the ability to think and is smart enough, when Zhang Mu hypnotizes the worm, he only needs to direct the next few worms to attack the worm. The king's order.

The second point is more obvious. No matter what kind of bug, the spiritual attributes are very low, and the resistance to various illusions is low, including the king of bugs. Zhang Mu was very confused at first, but now he finally understands the reason. After the worm, it is necessary to control tens of thousands of people. If each worm has strong mental resistance, the worm will have exhausted its power and died.

From the birth of the swarm, the resistance to spiritual energy is almost zero. In this way, the swarm creates a fatal weakness, which cannot resist the attacks of spiritual spells and is easily disturbed by illusions!

Zhang Mu whispered, "I went to try the insects first and then the depth, you stay in place, no matter what happens, do not act lightly!"

The scorpion and Wang Ling entered the invisibility, Zhang Mu stepped out of the rock gap, carefully approached the insect, and wanted to measure the alert range of the insect. However, Zhang Mu walked up to 300 meters before the insect, and there was no sign of detection.

Can't move forward, otherwise they will be caught by the queen guards.

Several nanny worms walked to the front of Roshan, and at the same time spit out the "nutrient solution" that was swallowed into the stomach and fed it to the worm.

"Can't find me this way?" Zhang Mu was a little dazed. "The queen does not seem to have sensory functions, nor does it have the ability to transcend the senses beyond the senses. So, how does it detect the outside world?"

Zhang Mu carefully walked out of the corner. There was a huge hatched egg in front of him, taking care of a group of eggs on the ground. Zhang Mu suddenly thought of a possibility, and slowly walked towards the hatched eggs, about 50 meters away. Zhang Mu stomped his feet gently and made a sound.

The hatched worm felt immediately, squeaked, turned her head, and stared at Zhang Mu with red eyes.

"Mum ..."

It was almost at the same time, when Roshan trembled, the guardian insect that had originally turned his back on Zhang Mu immediately turned around violently, and the roaring carapace suddenly opened, and it actually emptied and flew towards Zhang Mu.

"Hell, this guy can fly!"

Immediately after executing the order, the guardian worm released the mental wave behind the worm. Zhang Mu had no time to escape, and that spiritual power entered the brain, his will suddenly sinking, and he felt a strong feeling of lethargy-hypnosis!

(Thank you 6267 for your reward!)
