Riya didn't directly answer.
She knew very well that the matter of these magic beasts might follow them for a long time and Riya didn't know how to explain her knowledge.
Moreover, what kind of excuse would be suitable?
"I guess it?" Riya answered with unsure tone.
Ruby looked at Riya helplessly and then said, "If you don't want to answer, you can choose not to answer instead of giving such an answer."
Riya scratched the back of her head.
Looking at this friend of hers, Ruby realized that everyone around her might have some big secrets on their own. Just from Amelia's practice just now, Ruby felt that Amelia was really strong. And now, Riya also seemed to have some knowledge that other people didn't know.
But Ruby would not ask them about this.
She knew very well that if she were to rashly try to seek the truth from them, she might not be successful.
And their relationship would deteriorate instead.
Rather than doing this, it would be better for Ruby to pretend that she knew nothing and just follow along with their pace.
But it would be better for Riya to be careful.
"Even if you know more of these magic beasts, don't let others find out," Ruby added. "Knowledge is power and at the same time, knowing too much will only bring you demise."
As a person who wanted to become a researcher, Ruby understood how much the power the knowledge from these research would bring her.
It was also because she knew that she didn't want others to take advantage of Riya's knowledge. If it was only her and Amelia, Ruby would not mind because they would not take advantage of Riya.
But if it was others…
Who knew what they would do.
"I know." Riya smiled. "Thank you for your reminder."
Riya would not tell others about her knowledge and so on. She was not so stupid that she would expose the fact that she was very knowledgeable to others so easily. Even without Ruby's reminder, she would not do that.
The only reason why she still told Amelia and Ruby was because she treated them as her close friends.
She couldn't tell some things, but these things were important for their survival.
After all, Riya had spent four years or so in that world where she had no one she could truly trusted. In that world, she had faced many cruelties and challenges that was far from comparable to what existed in this world.
If she had foolishly trust others, she would not be able to survive for such a long time.
"Let's prepare your bedding for tonight. And how about if we set up night watch so that if these magic beast come closer, we won't be caught unprepared?"
"That's a good idea."
With that, they started to arrange a new place to rest for Ruby and then arranged for the night watch.
Amelia trained until she was tired and felt that her strength had improved. Even though Amelia was usually coquettish and lazy in her training, but she knew that their lives depended on whether she could defeat the magic beast or not.
So this time, Amelia trained so hard.
This made both Riya and Ruby touched. They knew how hard it was for Amelia to do this.
"Alright, we still have to rest. Go to sleep for now," Riya said.
"Okay. Thankfully the AC is still on or I'll die in this heat," Amelia mumbled in a low voice.
The temperature was still so hot that it was easy for them to have heatstroke. But their room was still a bit cool thanks to the air conditioner.
Riya smiled but didn't explain.
That air conditioner was already half broken after the earthquake. What maintained the temperature was her talisman that she had placed.
After Amelia and Ruby fell asleep, Riya silently slipped out.
The obstacles that they put beside the stairs couldn't stop Riya in the slightest bit as she stepped out and then raised her hand.
A defensive formation covered the entrance.
No one would be able to enter without alarming her and with the strength of these magic beasts outside, this formation is enough.
Riya lightly stepped out and looked at these magic beasts that were roaming around. They sensed the arrival of someone and twitched their body to look in Riya's direction.
"It has been a long time." Riya chuckled.
The next moment, Riya raised her hand and a formation circle appeared in front of her.
The way of a formation mage to fight is different from ordinary mage. If ordinary mage only needed to cast their spells, then the formation mage had to use the runes directly to show the result they wanted.
And the good formation mage could cast a small formation circle for spells in an instant.
Magic arrows penetrated through these magic beast from the formation circle in front of Riya. None of them could get closer to Riya in the slightest bit.
"So easy," Riya muttered in a low voice and with a sweep of her hand, these magic beasts corpse were put into her world.
The magic beasts were essentially animals that had assimilated mana into their body. If their bodies were decamped, it would turn into nutrition and also mana, which would enrich her world.
As for the other use?
Eh, these unranked magic beast were too weak in Riya's opinion.
If there were some ranked magic beasts, then she might be more interested.
'For now, let's eliminate them all.'
Riya swiftly stepped forward and then used her magic to slowly but surely eliminate these magic beast. She had to go out with Amelia and Ruby, so the best way was for these unranked magic beasts to die.
Tonight, it was a sleepless night.
For both the survivors and also the magic beasts.
Because these magic beasts found out… they were also the prey in the hands of someone stronger.
