In the evening of that day, there was Candy KTV in Central Square, Black Street Entertainment City, District 3, Shashi.
"Is this here?" Lang Hua asked quietly.
Yang Xiaoxiao nodded affirmatively and replied: "You can't be wrong. After the 'Advent Day', the base of Chaosandao and Qinglonghui will be located here."
The surrounding simple horse barriers and obstacle railings are still intact, indicating that this place has not been invaded by wandering corpses since San Dao and his party left. So... is there anyone else in there now?
Lang Hua nodded and signaled the two girls to move away, and took the lead in pushing open the front hall door.
"Squeaky."
In the humid and gloomy weather shrouded in black mist, the door shaft rotated sluggishly, and the strange noise it made was not loud, but it made people's scalp numb.
Without Lang Hua's instructions, the three of them separated automatically and searched deeper into the KTV along different routes.
…
Ten minutes later, Lang Hua and the other three met again in the back hall.
He tilted his head and asked, "Sister Qian, Xiaoxiao, how are you doing there?"
Yang Xiaoxiao shook his head and said: "No, there are neither black corpses nor living people."
Lin Qian also nodded to indicate that the situation was consistent.
Lang Hua smiled and said: "Everyone went out to take my life. This three-sword attack is a desperate move."
"If you lose, you will lose all your money." Lin Qian added with a chuckle.
"If the knife handle head can escape, he will naturally have a chance to make a comeback." Lang Hua sneered and continued, "Unfortunately, I have no intention of letting him die with three swords."
"Brother Lang Hua is the most powerful, no one can compare with him!" Yang Xiaoxiao's tone was very serious and serious, which actually made Lin Qian smile.
"Don't be poor."
Lang Hua tapped Yang Xiaoxiao's forehead with his finger: "Tell me more about the details of this KTV and see if there is any useful information left out. The 'Black Mist Vortex' was cherished by Chaosan Dao. It has been here before." The defense is tight and there’s no reason the baby would be anywhere else.”
"Ah, why are you asking me?" Yang Xiaoxiao blinked innocently.
"Yes," Lin Qian said with a smile, "Xiaoxiao, you sounded brisk and you seemed confident. Do you have a clue?"
Lang Hua said expressionlessly: "In the past two years, haven't you secretly played with your friends all night long?"
Yang Xiaoxiao was dumbfounded, her face a little stiff.
She thought to herself: Do you know this? What else do you know?
If there was no evidence that Lang Hua was immersed in physical training every day, she would almost suspect that she was being followed and monitored.
"Oh. Many times." Upon hearing this, Lin Qian let out a long, drawn-out tone.
She teased: "Hey, good student Yang Xiaoxiao... how could you come to a place like this? You stayed up all night, Xiaohua, you are really kidding me."
"Okay, okay, let me tell you." Yang Xiaoxiao immediately apologized, "I heard from the waiter here that there is a small icehouse underground in the KTV to store edible ice."
Yang Xiaoxiao covered her face with her hands, crying from the bottom of her heart... Well, the image of a good baby that she had worked so hard to cultivate was completely destroyed.
Perhaps this setting has never been established in the first place. These two old fritters...555~I am too embarrassed to see anyone.
"Underground cold storage?" Lang Hua suddenly realized, "That's it, let's go!"
Walking through the messy bar and blood-stained corridor, the three of them could almost imagine the doomsday scene on the night of Advent.
This is not difficult. When a disaster occurs, there is no difference in every corner of the world. It is nothing more than chaos and blood. But entering the place where such an incident took place will make people feel more immersive.
A downward step appears at the end of the corridor, leading to a small cold storage on the basement floor of Candy KTV.
In the corner of the cold storage, in front of the three people, there was a strange thing that was spinning on its own, resembling a miniature tornado. What was in front of them was what Lang Hua called the "black mist vortex", but its scale was really small.
Compared with the deep and gloomy black fog that covers the sky, this "black fog vortex" is only as high as an adult's calf, rotating at a constant speed, with a diameter and width of less than 30 centimeters, and is very slim and cute.
Yang Xiaoxiao leaned over and examined it, and couldn't help but reach out and touch it to have a look.
"Pah", Lang Hua, with quick eyes and quick hands, reached out and knocked off Yang Xiaoxiao's little claws, and taught him a lesson, "Don't touch things you don't know the origin of!"
"Ah, it hurts." Yang Xiaoxiao puffed up her cheeks in frustration.
She was complaining bitterly: "A cruel warlord leader, a representative of evil forces who doesn't understand how to show mercy to women."
But Xu's voice was a little soft, and Lang Hua didn't hear it clearly. He asked: "What?"
"No. I'm complimenting you." Yang Xiaoxiao rolled her eyes angrily.
"Is that so?" Lang Hua was a little confused.
"Xiaohua, is this what you are talking about?" Lin Qian pointed at the vortex and tried to smooth things over, "Is it dangerous for Xiaoxiao to encounter it?"
"That's right." Lang Hua's face softened and he raised his hand to gently rub Yang Xiaoxiao's wrist. He explained warmly: "This is a small 'black mist vortex', which is the product of the 'blowout' of spore black mist."
In Lang Hua's memory, the black fog of spores permeated the world after the disaster, and due to the colony habits of the black fog spores, there were "blowout outbreaks" twice a year.
During the "eruption" period, various indicators of the spore black fog increased exponentially, and the concentration of the black fog surged, approaching the situation on the night of "Advent Day". When the sun rises the next day, the black spore fog becomes thinner again, and everything returns to normal...
But returning to normal is just a look.
According to the observations of climatologists who survived at the time, after each large-scale black fog eruption, the concentration of spore black fog increased worldwide, and the earth's ecology was transformed to a deeper level.
The "Black Mist Vortex" is the legacy product discovered after the black mist eruption of spores has finished and receded.
The concentration of black mist in the black mist vortex depends on the degree and scale of the current 'blowout' of spore black mist, and is much higher than the current concentration in the atmosphere, so it contains higher quality spore crystal nucleus energy.
In the eighth year of the end of the world, some experts and scholars speculated that the "black mist vortex" was an accidental product of the encounter between the spore black mist ecosystem and the earth's original ecological climate.
Under various natural or man-made coincidences, such as temperature, humidity, air circulation and other factors, part of the black fog is restricted and cannot recede with other black fog. The fog remains in place, condenses, and swirls into itself, forming one "black fog vortex" of different sizes.
Right now, Candy KTV is a typical small "black mist vortex".
But even a small black mist vortex is something that ordinary people can encounter but cannot seek.
The formation of a black mist vortex from the spore black mist body is a small probability event. After the vortex is generated, it will last for a period ranging from one month to three years, depending on the environment, and then slowly dissipate.
The city has dense buildings and complex environment. The probability of vortex generation is only slightly higher than that in the wild, but the maintenance time is several times that of the outdoor environment. But in the middle and late apocalypse, the black corpses in the city are densely populated and terrifying in strength, and they are no longer the domain of humans.
He was lucky enough to encounter the vortex of black mist in this small cold storage.
Lang Hua thought to himself, then turned to explain to Lin Qian and the others: "The danger is certain. The energies of heterogeneous crystal nuclei are inherently conflicting with each other, and rash contact will only increase the burden on the limbs, and in severe cases may even cause the collapse of human tissue."
Yang Xiaoxiao looked scared and covered her mouth: "It's so scary, it's like poison. Where is the 'good thing' you said?"
"Things are naturally good things, but it depends on how to use them." Lang Hua didn't waste any more time and took out a crystal core from the medicine box - it was the lowest-level pink black corpse crystal core.
He brought the crystal core near the black mist vortex, pushed it gently with his palm, and the crystal core came to the center of the vortex and hung motionless.
After a while, the rotation speed of the "Black Mist Vortex" suddenly accelerated, and it gradually liquefied and concentrated, covering the black corpse crystal core in the center with a thin layer of emulsion. The black and gray vortex airflow gradually returns to transparency and then disappears. At the moment when the vortex disappeared and the crystal core was about to hit the ground, Lang Hua reached out and took the black stone crystal core in his hand.
At this time, the appearance of the crystal nucleus has returned to its original state, except that the entire crystal nucleus has become larger and the pink color has turned into an unpleasant light gray.
"It's crystallized...it's actually crystallized." Yang Xiaoxiao looked at the scene in front of her in disbelief and stuttered.
"It should be called segregation," Lin Qian added thoughtfully, "or it might be like the formation phenomenon of rain and fog." She asked Xiang Lang Hua: "The previous crystal nucleus should have played a role in catalyzing or acting as a crystal embryo. .”
"Smart, as expected of Sister Qian." Lang Hua hurriedly praised, with a smile on his face that looked very naughty...
Lin Qian raised her eyebrows, feeling a little proud. On the contrary, Yang Xiaoxiao pouted her mouth and turned her head, almost as if she could hang a small teapot on her mouth.
Seeing Yang Xiaoxiao's appearance, Lang Hua couldn't help coughing to resolve the embarrassment.
He continued: "However, things like the black mist vortex are not suitable for use by hidden symbionts like humans. Forcible contact will only cause the tissue to collapse."
Lang Hua narrowed his eyes and guessed: "Chaosandao must be simply resting near it to capture the free crystal core energy and increase the speed of promotion. However, this approach will increase the rate slowly."
"And I use a black corpse crystal core as a carrier to collect the energy in the vortex once and for all. After that, I only need to prepare this 'vortex crystal core' into a potion, and I'm done."
After saying that, Lang Hua raised his eyes and looked at Yang Xiaoxiao and Lin Qian, hoping to get some applause.
Unexpectedly, Yang Xiaoxiao just curled her lips and said, "Wow, that's awesome. Phew..."
Lin Qian couldn't help but find it funny and burst out laughing.
…
"Brother Lang Hua, what are you holding?"
Seeing Lang Hua take out a small jar of colorless liquid from his backpack, Yang Xiaoxiao couldn't help but ask a question, which was regarded as giving him a step down.
"Pharmaceutical solution, keep an eye on it."
Lang Hua didn't waste any time and put in the special crystal core formed by the black mist vortex. In just a moment, the entire crystal core melted into it.
After asking the two girls to guard the hall, Lang Hua sat cross-legged in the corner, tilted his neck and drank the bottle of instant potion.
The finished pharmaceutical solution that can be prepared in advance is not without its shortcomings. The energy conversion rate of allogeneic crystal nuclei for the crystal nucleation agent prepared using "instant solvent" is 10% lower than when prepared in the laboratory.
Considering how valuable the "Black Mist Vortex" is, even if it is only 10%, it will be a huge waste.
But at this time, Lang Hua couldn't care less about these "little things".
Another reality is before everyone's eyes - as time goes by, post-disaster cities will only become more and more dangerous.
