After the summoning countdown appeared, Lu Heng and Su Muyu discussed the possible reasons for the summoning.
Since there were no special events happening around them at the time of the summoning, there must be another reason for it.
Lu Heng first sent a message to Chen Linian, requesting an investigation of significant events that occurred within an hour of the countdown's appearance.
However, they couldn't find the reason.
Chen Linian did send over the record of special events that happened during that period.
But, these events seemed to have no connection to the summoning.
"If we can't find the reason for the summoning, we might as well prepare as usual," Su Muyu had already decided, quickly making two pieces of jewelry before the transport to enhance the team's combat power.
Although the Inscription Gems she was making now could only increase spiritual power by 4 points, along with adding one Engraving Attribute, it wasn't a significant boost, but every little bit helped.
Lu Heng glanced at the team group chat and didn't see any messages from Lin Zeyu, guessing that this guy hadn't realized he was summoned yet.
The countdown was 7 days, so there was no rush.
Su Muyu thought of someone and asked, "Should we get in touch with Xie Shi'en? Telling him that we've been summoned might be a good idea."
"Sure, I'll check my email."
Lu Heng logged into a seldom-used email account and found no new emails.
Then he opened a website for sending anonymous emails, preparing to send one to Xie Shi'en.
The email was just a contact code, nothing written on the surface, just appearing as a promotional email.
As he was about to send the email, his inbox pinged with a new mail.
Lu Heng opened it and saw that it was from Xie Shi'en.
"He's contacted us first, let's wait for him a while," Lu Heng closed the email and continued browsing the internet for useful information.
There was a knock at the door, Su Muyu had just made tea, and she walked over to open the door, teasing, "Finally caught on, have you?"
The visitor wasn't Xie Shi'en, but Lin Zeyu.
This guy had hurried down from upstairs after he noticed the summoning countdown.
"I was up all night practicing shooting, got too sleepy and dozed off for a bit, and when I woke up, I saw the summoning countdown. What's all this about?"
Lu Heng, who was browsing various pieces of information, casually replied, "We're also analyzing the reasons for the summoning."
After Lin Zeyu entered and saw Su Muyu had brewed tea, he raised an eyebrow and said, "Making tea for me? So formal, I'm a bit embarrassed."
Su Muyu rolled her eyes, "You wish."
Lin Zeyu blinked and asked, "Any more guests?"
A voice came from outside the door, "The guest you mentioned should be me."
Xie Shi'en stood at the door waving.
Lu Heng waved him in, "I was just about to send you an email, then I saw your email. What's up?"
Hearing this, Xie Shi'en raised an eyebrow and asked, "You guys... haven't been summoned, have you?"
Lu Heng nodded, "Yes, we're currently looking for the reason."
Some Abyss Battlefield summonings have no warning, especially the first time humans are summoned.
But some summonings have reasons, and if you can find the reason, you might be able to predict which Abyss World you'll be summoned into.
Xie Shi'en exhaled and said, "I might know the reason."
Lu Heng and the others immediately turned to look at him.
If what he said was true, it would mean they could know in advance which world they were entering and prepare more thoroughly.
"What's the reason?" Lu Heng asked.
"It might be my fault, if it's not a coincidence…"
Xie Shi'en took a breath and then surprised everyone with his next words, "I opened the lid of the Life Protection Box."
Lu Heng, who had seen that Life Protection Box before, widened his eyes and asked, "You opened the wooden stopper of that crystal bottle?"
That Life Protection Box was a dusky blue crystal bottle, sealed with a wooden stopper.
Xie Shi'en nodded, "Yes, I opened the stopper of the Life Protection Box, and when that drop of liquid evaporated, the summoning appeared."
After hearing his explanation, Lu Heng felt this situation was more complicated than expected and said, "Hold on, let's first confirm if our summoning times are the same."
If they were being summoned into the same Abyss Battlefield, the countdown would be identical, down to the second.
Xie Shi'en read out the summoning countdown, and after Lu Heng and the others listened, they exchanged glances and confirmed, "It's the same one."
Lin Zeyu looked puzzled and asked, "Why would you open that thing?"
Xie Shi'en appeared a bit embarrassed and explained, "The temperature dropped recently, and I noticed the micro-lights inside the Life Protection Box had condensed into a liquid, looking just like a drop of water. I wanted to extract a bit to see what substance it was, but as soon as I opened it, the liquid evaporated."
A month ago, Lu Heng had already seen the Life Protection Box, and at that time, he did notice some glints of micro-light inside the bottle, but he hadn't opened the stopper to check, nor was he certain what those micro-lights were.
Now, hearing Xie Shi'en's description, those micro-lights appeared to be a liquid.
If it was just an ordinary bottle containing a drop of liquid, there would be nothing strange.
But this bottle was a Life Protection Box, a Witch Demon's Life Protection Box.
The liquid inside was a bit more unusual.
Lu Heng pressed further, "What is the liquid? Did you manage to check?"
Xie Shi'en awkwardly shook his head, "I thought it was a liquid, so I wanted to use a dropper to take some out, but as soon as I opened it, the liquid evaporated. I couldn't see what it was, but from the scent I smelled, it's a kind of liquid containing special energy, with no trace of Evil Spirit."
