According to the [Ruthless Swordsman], although the white jade bottle looked only a little bigger than a palm, the space inside was very large, with 100 cubic meters. Pen, Fun, Pavilion www.biquge.info such a white jade bottle is sold in the system mall, but the price is too expensive, and Lan Ke never thought of buying it.

It's just that when she was setting up the stall at noon, she met the [Ruthless Swordsman] again, and thinking of the effect of the black rain, she tentatively asked the [Ruthless Swordsman] what he thought. As a result, [Ruthless Swordsman] was very interested in Black Rain, and after some discussion, the two sides finalized the intention to cooperate.

[Ruthless Swordsman] provides the white jade bottle, she provides the black rain, and the final income is divided fifty-fifty.

Lan Ke glanced at the white jade bottle suspended in mid-air, thought for a while, and said to Babao: "System, can you do an appraisal of the black rain now?"

Although he had seen the power of the black rain, Lan Ke was not sure at all, and he didn't know how many trading points such a black rain was worth, so he could only ask Babao to identify it.

If the black rain is valuable, of course, the more the merrier, if it is not valuable, then the remaining white jade bottle does not have to be taken out.

Babao stood on Lan Ke's shoulder, looked down at the rain on the ground, spread his wings and landed on the ground, his little paws stepped on the rain, and after a while, the identification results came out: "The rain contains unknown biological viruses, organisms may cause genetic mutations after infection, the direction of mutation is unknown, the attribute is a dangerous biochemical virus, the purchase price of the mall is 1 transaction point/100ml, and no plane transactions are allowed." ”

Lan Ke raised his eyebrows: "100ml is only 1 transaction point? This price is too low, right? What does it mean that you are not allowed to trade in the plane?

"In order to prevent plane merchants from maliciously spreading biochemical viruses, the plane trading system prohibits plane merchants from trading biochemical viruses with each other, and does not allow them to give away to each other, but the system mall can buy them. ”

After the Eight Treasures explained, he gave another suggestion: "The biochemical virus has spread, and it is best for the host to purchase exercises to cultivate as soon as possible to improve his own strength." ”

Lan Ke didn't expect that Black Rain could only be sold to the System Mall, and the purchase price was still very low. But Babao is right, she does need exercises now.

In her previous life, her awakened abilities were strengthened, but only the sense of taste and smell was strengthened, which were auxiliary abilities, and there was no advantage in combat. So at the beginning of the end of the world, she had a very hard life, and her life was also very difficult, struggling to survive every second.

This time, she didn't dare to have much hope for awakening, so she could only pin her hopes on the exercises sold in the system mall.

It's a pity that the price of those exercises is really terrifyingly high, and she doesn't have so many trading points at all, so she has the idea of selling Black Rain.

Tsk, I thought I could take the opportunity to make a profit, but who knew that the system would have such a limitation.

Lan Ke sighed, although the price of 1 trading point/100ml is not high, but the black rain will rain for three consecutive days, as long as the amount goes up, the trading points earned will not be less.

Thinking of this, Lan Ke simply took out all the remaining 9 white jade bottles, and threw them all out after reciting the formula.

The white jade bottle is obviously not an ordinary container, and it can even be called a magic weapon, as soon as Lan Ke recites the formula, the 9 white jade bottles automatically fly into the air, scattering to absorb those black rains.

It was very dark, and the white jade bottle disappeared after flying into the air, and no one else would notice it except Lan Ke, a temporary user.

The white jade bottle has a capacity of 100 cubic meters, and it takes time to fill up, and before they are full, Lan Ke can only wait. And just when Lanke was collecting black rain, research institutes in various countries also collected black rain samples and began to study and analyze them in full swing.

However, the black rain contains biochemical viruses, and if you want to study it clearly, you have to conduct live experiments, and it is not something that can be studied clearly in a while.

Lan Ke didn't stay on the roof all the time, and after making sure that the white jade bottle would not be discovered, she went back to her room and took a shower and slept well. Then, she was woken up by an urgent knock on the door.

At this time, it was already 10 o'clock in the morning, Lan Ke put on his clothes and walked quickly to the entrance, opened the cat's eye and saw that the person outside the door was a neighbor who lived on the other side.

Lan Ke was a little surprised, but didn't open the door, just asked, "What's the matter with you?"

Bai Lingzheng was flustered, and only after hearing Lan Ke's cold voice did he feel less panicked. Thinking of her recent discovery, she quickly said, "You...... I noticed that it was raining black outside, I took a little bit, the color was very dark, like ink, you ...... Do you want to take a look?"

"Oh, I already knew, this rain is quite weird, be careful when you touch it, don't get it on your skin, and don't go out lately. ”

There are biochemical viruses in the black rain, and there is a high possibility of genetic mutation after infection. This mutation has two directions, one is evolution, which is the ability to awaken, and the other is degenerate, becoming a murderous and bloodthirsty xenomorph.

Of course, there are some people who will not mutate even if they are infected, and they are still ordinary people.

Lan Ke didn't know what kind of young female neighbor it would be, so she simply told her not to touch it yet. Otherwise, if this person is unlucky and becomes a xenomorph, she will have to let it die.

Bai Ling nodded hurriedly: "I know, thank you." I won't bother you, you ...... You are also careful. She saw that Lan Ke didn't mean to open the door, so she wisely turned around and went home.

Back at home, Bai Ling stared at the black rain in the bowl as if he was facing a great enemy, hesitated for a moment, but still didn't pour it out. She wanted to see if anything would change about this strange rain.

After thinking about it, she simply turned on the tablet and swiped Weibo. There are a lot of messages on Weibo, and today's hot one is #天会黑雨#, comments and retweets have reached millions, and obviously many people are paying attention to this news.

Bai Ling opened the comments one by one, there were all kinds of speculations in them, and the more she looked at it, the more panicked she felt, and she couldn't help but glance at the door. Thinking of Lan Ke, who lived in the opposite door, she settled down a little, and felt that she was still quite safe.

Lan Ke didn't know that someone had already regarded her as a protector, she didn't even bother to read the news on the Internet, and after filling her stomach, she went to the roof to check the situation of the white jade bottle. Knowing that the 10 white jade bottles were not yet filled, Lan Ke returned home and continued to prepare cooked food.

Tang Family Villa, Tang Jingtian, Chu Jia, Tang Qi and Tang Qiong all stayed at home and did not go out. To be exact, they haven't gone out since the darkness shrouded them, leaving everything to the bodyguards and assistants.

The Tang family can now be regarded as a big business, and in addition to bodyguards, the family has hired maids, so there is no need to worry about safety at all.

But at this moment, looking at the continuous black rain outside, everyone's hearts seemed to be shrouded in a thick layer of clouds, and the uneasy premonition became stronger and stronger.
