The gift Han Yaozu gave to Lu Yu was a small piece of Millennium Ginseng.
Lu Yu wasn't sure exactly how many thousands of years it was, but judging by the richness of the Spiritual Qi of the Millennium Ginseng, it had a very significant effect on him.
Equivalent to the Primordial Spirit Fruit for a Martial Cultivator in the Body Refinement realm, consuming this piece of Millennium Ginseng gave Lu Yu a chance to advance a minor realm.
However, it wasn't the right time to consume the Millennium Ginseng yet, so Lu Yu replied to Yu Xiaoman's message, telling her that he was at the entrance of the training camp.
Soon, Lu Yu saw Yu Xiaoman's figure.
Feeling the aura of Spiritual Power on her, Lu Yu was a bit surprised, "You've broken through to the Qi Cultivation realm?"
"Yeah, I just broke through the day before yesterday. Now I can punch and break a tree!" Saying that, Yu Xiaoman raised her arm, showing that she now had great strength.
"What is this Underground Demon Den you mentioned? Wasn't your mentor looking for me? Why isn't she here?" Lu Yu asked curiously.
"Mentor Ling took the students to clear out demons and isn't in the city." Yu Xiaoman gestured in the air, pointing at Lu Yu, and continued, "As for the Underground Demon Den, it's likely related to this quest, Mentor Ling hopes we can go and destroy the demon den."

Lu Yu received a system prompt.
[Player Yu Xiaoman has shared a quest with you—Destroy the Demon Den, do you accept it?]
Lu Yu accepted the quest and, after reviewing the detailed information, understood what the Underground Demon Den was.
The City Lord of Beifeng City had invited an Array Master skilled in seals, who set up a super array to lock the demons within it, preventing them from leaving the array's range.
However, the Heavenly Poison Centipede, whose mind was corroded by Demonic Qi, used many demonized creatures to establish the demon den, which constantly produced demons and Demonic Qi.
Normally, the many Core Formation Realm experts in Beifeng City wouldn't allow the Heavenly Poison Centipede to establish such a den, but it managed to make itself the vessel of the demon den, creating a den that could move underground, leaving even the strongest experts with no way to destroy it.
Every day demons appeared outside Beifeng City and sometimes even inside it, endangering the towns and villages within the sealed array's range as they frequently suffered demon attacks.
Demons hunted humans, livestock, and monsters to provide flesh resources for the demon den, continuously producing new demons. As long as the demon den wasn't destroyed, demons would not cease to exist.
For players, the appearance of demons wasn't necessarily a bad thing, as quests related to demons increased rapidly, and the demons' inexhaustible nature provided players with many monsters to farm for experience points.
Yu Xiaoman's quick leveling up to the Qi Cultivation realm was probably related to the demons as well.
Following Yu Xiaoman, Lu Yu left Beifeng City and headed towards the frontline of the battle between humans and demons.
Students from Beifeng Academy, family members and guards from Beifeng City, as well as wandering Martial Cultivators and players, were all gathered around the Demon Well.
The Demon Well was a passage drilled open earlier when the Heavenly Poison Centipede was chasing Lu Yu, leading to an underground river, from which many demons emerged.
The top officials of Beifeng City believed that the Heavenly Poison Centipede was likely hiding in the underground river.
Several Core Formation Realm experts had once ventured through the Demon Well and into the underground river but couldn't find any trace of the Heavenly Poison Centipede, suggesting it had sensed the threat from the Core Formation Realm experts and hid beforehand.
In the underground, if the Heavenly Poison Centipede wanted to hide, even Core Formation Realm experts couldn't find it.
Dispatching Martial Cultivators in the Qi Sea realm into the underground river wouldn't make the Heavenly Poison Centipede hide, but those cultivators were simply not its match in the underground world and were essentially marching to their deaths.
When there were many people, the Heavenly Poison Centipede would hide and ambush. If there were few, going down would mean certain death.
The City Lord of Beifeng City had never encountered such a tricky opponent and could only instruct the army and recruited Martial Cultivators to first clear the demons on the surface, while other experts brainstormed ways to destroy the demon den within the Heavenly Poison Centipede.
Lu Yu and Yu Xiaoman arrived thirty miles away from the Demon Well, where the area had already been encircled by the army's defensive line.
Along the way, Lu Yu saw many demon corpses and numerous villages and towns destroyed by demons. Besides the commercial operations within Beifeng City, the streets of villages and towns were completely deserted.
Villagers with connections had already fled into Beifeng City, while those without dared only hide at home without venturing outside.
Ordinary people were too weak against demons; getting even a little too close could mean being corroded by Demonic Qi and becoming demonized themselves.
Whoosh! A small, ancient arrow flew back into Yu Xiaoman's hand as she killed a demon equivalent to a Martial Cultivator in the Qi Cultivation realm.
Somehow, she managed to control that little arrow in flight, remotely managing to control objects, something Lu Yu couldn't do, yet Yu Xiaoman could.
Lu Yu took a few more glances at the little arrow, considering that the secret probably lay with it. He thought of Chu Tiange's Bronze Chariot, which could be maneuvered even though Chu Tiange had not a trace of Spiritual Power in him.
Could the little arrow be like the Bronze Chariot, a Divine Artifact?
Since the marketplace currently had no Divine Artifacts for sale, Lu Yu was unclear about what exactly a Divine Artifact was, though he roughly understood that it should be an item surpassing Spiritual Treasures, possessing inherent mighty powers.
Yu Xiaoman held the little arrow and, noticing the shock on Lu Yu's face, smiled.
"Now, I'm really powerful too!"
The two had just arrived at the barrier line when Ling Yuyan appeared on its edge, and feeling the aura on Lu Yu, she was a bit surprised, "You've been gone for just seven days, and you've already advanced to the sixth level of the Qi Cultivation realm?"
