Chapter 91: Unlock temporary swarms

What does this temporary option mean, do I need to activate it after upgrading?
Liu Feng asked the system first, so as not to run out of experience points he had hardly collected.
Sure enough, this temporary skill is not cheap. If he just chose to upgrade, it would be equivalent to giving up this temporary skill.
[Unlocking the temporary new insect swarm skills requires 10,000 experience points, valid for 24 hours, and the host's normal upgrade system will not be affected. 】
[May I unlock a new swarm? 】
Unlock!
Liu Feng accepted it without hesitation, and soon the system showed the function of the new swarm, which made him feel a little strange.
[Unlock temporary new insect swarm: Withered butterfly, through its own interference band to confuse the enemy, within a certain range its attached objects and humans can produce invisible effects. 】
Invisible?
Liu Feng looked at this function thoughtfully. If humans can really be completely invisible, wouldn't it be necessary to be afraid of confronting zombies anymore.
[Again, the function of the temporary swarm is only 24 hours. After 24 hours, no matter how many levels the swarm is upgraded, it will automatically disappear. Please use the experience value carefully. 】
The system regards Liu Feng as a novice player, carefully explaining each new feature.
This temporary insect swarm needs 5000 experience points every time it is upgraded. If it reaches the top level, all the experience points that Liu Feng has just accumulated will be dedicated.
The Lv1 withered butterfly function is very simple, can only hide static objects, and can only release 10 at a time, making Liu Feng feel that he has mastered a very tasteless skill.
System, raise the level of the withered butterfly to Lv2.
Liu Feng was forced to upgrade the level of the withered butterfly to another level. This time the withered butterfly can finally move slowly with the object, but there are very strict requirements on the range that it can hide. At present, it can only hide the volume not more than 1 cubic meter. The object of rice.
Fortunately, the number of withered butterflies has increased significantly this time, and 100 can be released at a time.
"What's wrong with you, is there something wrong?"
After seeing Liu Feng staying still, Xiao Q stabbed him in the arm. The surrounding zombies were almost cleared, and even the howling noises were getting smaller and smaller. According to the current situation, they would do it within an hour. You can call it a day.
"Don't be too happy too early, maybe the real hard food is still behind."
Liu Feng has played games before, but any temporary increase in skill options must be related to the current situation.
He felt that the calmness of the playground was only superficial, and there must be a larger wave of corpses behind.
"It's okay, Xiao Q, let's go down for a walk."
Liu Feng drove the car in front of a huge building. The appearance of the whole building was like a rockery with a huge grimace painted in the middle. It should be a haunted house in this playground.
This place is in the very center of the playground, and the surrounding roads extend in all directions. It can gather zombies from various places. It is a good place for leaders to settle down.
"What are you kidding? How am I going like this now? What's more, why is this place? Isn't the roller coaster higher than here? If I were a zombie, I would definitely choose there, and I could be condescending."
Little Q pointed to the wooden building in the distance. The roller coaster could indeed have a bird's eye view of the entire playground, but Liu Feng didn't believe that the bare railroad tracks were a good place to hide himself.
This Boss-level zombie has been hiding in the dark to direct the actions of other zombies. He will definitely choose a fighting position that is most beneficial to him. Even if all the power is turned on in the entire playground, there will be no light. Place, I am afraid there is only this haunted house.
What's more, Liu Feng has just observed very clearly that most of the intermediate zombies dragged out by the Hydralisk come from this haunted house. The things that can make them desperately protect, even if it is not a big Boss, are more interesting than attacking the little ones outside. Up.
"No, Liu Feng, you can't go crazy. I am like this. If you send me in, you are sending me to death."
Xiao Q was struggling constantly in a wheelchair. Her combat effectiveness was extremely weak. In such a place that was obviously powerful against zombies, she had almost no possibility of escape.
She looked at Liu Feng in horror and felt that he had brought herself here to die.
"If I wanted to kill you, I just pushed you out of the car. Don't worry, you will be fine. Those zombies can't see you at all."
Liu Feng took out a dry butterfly and placed it on Xiao Q's shoulder. This dry butterfly had no effect on Liu Feng. Xiao Q did not disappear in front of his eyes, which made him somewhat doubt the ability of these dry butterfly.
"What are you doing, just find a dead leaf to send me away! What is the difference between this kind of thing and the king's new clothes!"
There was some anger on Xiao Q's face. He felt Liu Feng coaxed her again. He obviously had so many powerful insects, and just taking out one would be more effective than this broken leaf.
She pulled her shoulder, and the withered butterfly instantly fell on her wheelchair, making the entire wheelchair disappear.
"What's the matter?"
Seeing her body floating in the air, Xiao Q felt incredible. She looked at Liu Feng in a daze, thinking that he must have used some kind of magic.
"All said, I have a way to keep those zombies from seeing you."
Liu Feng summoned dozens of withered butterflies, hidden their heavy trucks, and placed another withered butterflies on his shoulders. He found that these withered butterflies had their wings together when they were working. When resting, the wings will spread to the sides, which is very easy to distinguish.
"Liu Feng, where are you, I can't see you anymore, stop making trouble, come out quickly."
Xiao Q was particularly anxious when she saw Liu Feng disappear in front of her. She fumbled around, as if she was a child who had lost her parents.
Liu Feng is only invisible, but the sense of touch will not disappear. The position where Xiao Q fumbled is not suitable, making Liu Feng instinctively take a step back.
This sudden loss of dependence made Xiao Q even more panicked. She kept shaking her wheelchair, trying to move in the direction of the hotel.
"I'm here, just invisible, don't run around."
Liu Feng put his hand on Xiao Q's shoulder, he found that as long as their bodies are in contact, they can be regarded as the same object by the withered butterfly and can see each other.
He pushed Xiao Q to the door of the haunted house. Before entering, he felt the wind gusts inside, and the roaring sounds were very chaotic, and he couldn't distinguish whether it was a machine or a zombie.
"Liu Feng, can they really not see us?"
Xiao Q was very nervous and kept holding Liu Feng's finger tightly, but Liu Feng downplayed the incident.
"I'm not very clear, just give it a try."
