Chapter 327 Preparing for the Demons' Invasion

"Grandfather, this isn't the time to joke. We have an emergency." Lan Yingying said to him as she retrieved the demon core and showed it to him.

"Hmm? What's that?" Grandpa Lan didn't immediately recognize the demon core since it has been many years since he last saw one.

However, when he finally realized what he was looking at, his eyes widened with surprise, and his playful expression turned solemn.

"Where did you get that demon core?" He asked her in a serious voice, and he continued, "Let's talk inside."

A few moments later, they returned to the table.

Once all four of them were fully seated, Lan Yingying recalled their encounter with the demon and how Yuan defeated it.

"We were attacked by a demon on our way to the city," she started off with this shocking information.

"What?! Impossible! The Lord's Sword Aura should have prevented them from getting so close to the city!" Grandma Lan said.

"Yes… But they absorbed my parents' blood, granting them resistance to the Sword Aura." Lan Yingying sighed.

"They what?! These damn demons!" Grandpa Lan slammed the desk in a small fit of rage.

After a moment of awkward silence, Grandma Lan spoke, "Then what happened to that demon? Surely, you didn't kill it, since we know you can't kill demons yet…"

Lan Yingying nodded and said, "The demon was killed, but I was not the one who killed it."

She then turned to look at Yuan and continued, "Yuan was the one who killed it."

"Y-You?"

The grandparents turned to look at Yuan with disbelief written all over their faces. How could a human that's only a Spirit Warrior kill a demon? Judging by the energy coming from the demon core, that demon should've been no weaker than a peak Spirit Master.

A Spirit Warrior defeating a peak Spirit Master? In what world would this make any sense?

"H-How on earth did you kill the demon?" They asked him a moment later, still with a dazed look on their faces.

"I used a sealing technique on the demon before finishing it off," Yuan responded in a casual manner, acting like it was only an ordinary magical beast that he'd slain.

"Sealing technique? Are you perhaps from the Demon Sealing Clan in the outside world? They were always there to help whenever a demon was involved." Grandpa Lan asked him.

Yuan shook his head, "No, I am not associated with the Demon Sealing Clan. I learned the sealing technique by chance."

"B-By chance, you say?" The grandparents looked at each other.

Demon sealing techniques are incredibly rare because the Demon Sealing Clan seized most of the techniques during the ancient times and forbade people from sharing the technique with strangers, as it was the pride of their family and what made them unique in the cultivation world.

Therefore, learning such a technique 'by chance' was very unlikely.

"Anyways, let me continue. The demon Yuan slew said that the rest of the demons intend on raiding the Divine Forest in two weeks. What should we do?" Lan Yingying asked them.

"Two weeks, huh?" They mumbled before turning quiet to ponder.

After a long moment of silence, Grandpa Lan looked at Yuan before asking him, "What do you plan on doing, young man?"

"I'd like to help you with whatever I can," he quickly responded.

"I see… We greatly appreciate it, and your demon sealing technique will definitely help our situation a lot, but are you sure? It's going to be very dangerous fighting against the demons."

"Since you already killed one, there should be four demons left, including the Demon Lord, who is the most powerful of them all. And judging from the demon core you got, that demon was probably the weakest of the bunch."

"If you stay here with us, we cannot guarantee your safety."

Yuan nodded and said, "There's still two weeks before they attack, right? That's plenty of time for me to increase my strength."

"Uhh… I guess…"

In their eyes, two weeks was no different than two days, and not many improvements can be made in such a short time even if he was a peak genius. If Yuan was given two years, perhaps he might be able to assist their fight with the Demon Lord, but at his current level, he wouldn't even be able to get in range to attack the Demon Lord without dying.

"I understand. If you need anything at all, just let us know." Grandpa Lan said to him.

Hearing such words, Yuan didn't hesitate to ask, "Then do you have any monster cores?"

"Monster cores? No, we don't. However, we can hunt some magical beasts and get you some." Grandpa Lan said.

"How many do you need? Most magical beasts around this area are above Spirit Master."

"I want as many as possible if you don't mind," Yuan said without hesitation.

"I understand. I'll go hunt some magical beasts after this."

"Thank you for the trouble," Yuan said to him.

"Hahaha… Don't mind it. No amount of monster cores will be able to match a demon core for us."

Sometime later, Yuan asked them, "By the way, I have been wondering… Since Miss Lan is a Divine Beast, does this mean both of you are also Divine Beasts?"

"Oh? Yingying told you about it?"

Yuan nodded.

"That's right. I am also a Divine Beast. However, Grandma Lan here is not a Divine Beast."

"My real form is a Jade Serpent— I am just an ordinary magical beast." Grandma Lan said.

"When a Divine Beast mates with an ordinary magical beast, the baby will always be a Divine Beast, but we can only have one child in our lifetime." Grandpa Lan explained to him.

"I see…" Yuan mumbled.

"Anyways, if the demons want to attack us, we'll be fully prepared for them." Grandpa Lan said.

"However, it won't be easy defeating four demons when there are only two of us who can actually kill the demons— me and you, young man."

"I'm going to hunt some magical beasts right now and see if I can get you some monster cores. In the meantime, you can stay here with the other two. Of course, if you want to be more productive, you can always mate with Yingying." Grandpa Lan said with a smile on his face before leaving the cabin.
