"What oath does the Taoist friend want me to take?" The girl smiled slightly, thinking that since the other party had voluntarily offered her treasures and then asked her to make a heavy vow, they probably didn't have any intention of killing her. If they let her leave freely, she would find it strange instead.

  "The fairy and your ancestor have a deep affection for each other, why don't you use your ancestor's oath? This way, the lower realm will naturally trust the fairy!" Zhao Di replied after a moment of thought.

  The girl's face turned cold as frost, and she said: "Xian Xian will not use her ancestors' oath! But Xian Xian is willing to swear on her own heart that she will not reveal a single detail of today's events. If she does, she will become someone else's furnace and cauldron, suffer all kinds of torture, be invaded by demonic energy, and have her cultivation completely ruined! If fellow Taoist is still not satisfied, you can take back this jade bottle!"

  Zhao nodded and said, "I was careless earlier, not intentionally targeting your ancestor. The immortal is a person of utmost sincerity and nature, every sentence comes from the heart, how could I dare to distrust!"

  The girl also heard Zhao Di's words and was extremely sincere, and didn't make any more calculations.

  Zhao Di said: "This demon is extremely troublesome, we should leave as soon as possible. Whether the immortal continues to go elsewhere to find treasure, I will first escort the immortal out of this place."

  "Thank you, fellow Taoist! With the treasure you've given me, I'm completely satisfied with this trip. Once I've dealt with Song Shijie's corpse, I'll leave this sealed space. Thank you again for your protection." The girl let out a light sigh, removed the storage bag containing the corpse of the woman surnamed Song from a nearby location, and transferred the body into a new storage bag. Then she put away the jade bottle and took out the restrictive law disk without hesitation.

  After a while, the girl shrouded in white light gazed at Zhao Di for several moments before saying: "This trip has been made possible thanks to the help and assistance of Daoist friend, who also bestowed upon me precious treasures. Xian'er is once again indebted to Daoist friend for a great favor, yet still doesn't know how to address him."

  "In the land of Zhao!" Zhao Di smiled slightly.

  "Xian Xian lives in the Wuliang Peak of Taiyi Gate, if Zhao... Zhao Daoyou has any business, you can come here to find Xian Xian, Xian Xian will definitely do her best!" The girl's face was slightly red as she said this, and just after finishing speaking, a white mist flashed by, and the girl disappeared into the mountain cave.

  After the two girls were sent away, Zhao Di let out a soft breath, his mouth slightly curved upwards as he whispered: "Alright, now that there's no one else around, I'll keep you company, this ice demon."

  As he spoke, his sleeve shook and a dozen or so human-shaped puppets holding long bows fell in front of him. In his hand, he also grasped a four-foot-long crimson bone knife.

  Bing Feng Meng, under Zhao Di's command, was slowly leading the Ice Demon Xie, who was following closely behind, towards the puppet. Then, with a sudden burst of speed, it flew over the puppet.

  That Ice Devil also wasn't slow, immediately leaping into the air, its claws extended, ready to rip apart the body of the Frost Wind Python in mid-air.

  Suddenly a dense array of icy cones, golden blades, sharp stabs and long spears of spiritual energy attacks came from below, covering an area of over ten zhang behind the Ice Wind Python.

  The Ice Demon's body was agile and elusive, but this wave of attacks came pouring down like a landslide, leaving no room for evasion. The Ice Demon twisted its body in mid-air, barely avoiding most of the attacks, but two water arrows still struck its body, creating two black wounds the size of a palm.

  This minor injury to the Ice Demon is naturally of no great concern, and under its robust physical condition, these two wounds are gradually healing on their own. It's likely that they will soon recover completely.

  But in this brief moment, Zhao Di had already judged the position of Bing Mo Xuan from the wound, and with a swing of his hand, a fire dragon over ten feet long emerged, its jaws wide open as it pounced towards him.

  Bingmo Yan was greatly shocked, and he continuously jumped back several times, retreating more than ten zhang away. However, the fire dragon still chased after him with a speed that was even faster by one notch, and it swallowed him into its belly in one mouthful.

  A mournful howl, and the Ice Demon and Fire Dragon vanished together. A bright light flashed, and something seemed to fall from mid-air, only to be caught by Zhao Di's swift hand.

  "Is this the unique Crystal Core of Warcraft?" Zhao Di's palm was wrapped in a layer of purple gas, on top of which was a bright and translucent diamond-shaped ice crystal about an inch in size.

  "It's no wonder that this is an ancient sealed space, and yet there exists such a legendary magical beast that was thought to be extinct. If we were to give this crystal core to a cultivator who practices demonic magic, I'm afraid it would be worth quite a bit!" Zhao Di said to himself as he played with the crystal core in his hand.

  Unfortunately, the Ice Demon is equivalent to a fourth-level demon beast in the late stage of foundation building. This crystal core is not very useful either, and it still contains a thick demonic aura, so he can't use it!

  The Ice Wind Python also slithered over, its two fist-sized green eyes staring at the crystal nucleus in Zhao Di's hand with great interest.

  "What? Can you use this thing?" Zhao Di sensed the information transmitted by Bing Feng Man, slightly surprised. "It's true, this is an ice attribute crystal core, it may be beneficial for practicing ice attribute magic."

  But it contains a lot of demonic energy and cannot be ignored.

  To extract the demonic energy from within the Demon Crystal Core, it would be extremely difficult for someone who has never cultivated demonic powers before. However, for Zhao Di, who possesses all of the Blood Intent Sect's Young Master's treasures, it wouldn't be too complicated.

  He carefully took out a narrow jade box from his storage bag, muttered incantations, and lifted the seal on top.

  After the jade box was opened, a blood-red small sword about a foot long was revealed. It was the Blood Demon Sword of the young master of the Blood Intent Gate, but at this time, the small sword had been dull and lusterless for many years without feeding on essence blood.

  Zhao Di placed the crystal core next to the Blood Red Sword, softly chanting an incantation, his hands forming a peculiar hand seal that struck the crystal core.

  A wisp of dark energy drifted out from the crystal core and was absorbed into the Blood Demon Sword.

  After a brief moment of fragrance, the demonic energy in the crystal nucleus dissipated, and the color of the Blood Demon Sword also became slightly darker.

  Zhao Di carefully put away the Blood Demon Sword, re-sealing it in the jade box and storing it in his inventory bag.

  The crystal nucleus that had absorbed the demonic energy was checked repeatedly by Zhao Di and found to be normal, then tossed to Bing Feng Mang. The latter let out a joyful hiss and swallowed it in one gulp.

  "The Ice Demon isn't a creature that likes to be alone, there might be more than one around here!"

  Zhao Di carefully explored the cave and found four deeper passageways in addition to the entrance he came from.

  Zhao Di took out several spiritual tools and shields to protect himself, then went deep into a passage with Bingfeng Mang.

  As expected, he once again discovered an Ice Demon under the sensitive induction of Bingfeng Yan, and with the help of the puppets and the Blazing Sky Blade, he obtained a crystal nucleus without much effort.

  After carefully searching all three places in the four-way passage, Zhao Di obtained three more Ice Demon Crystal Cores.

  Another passageway led to a massive underground cave tens of miles in diameter. This cave was not only the largest, but also had the densest demonic energy, yet Zhao Di found nothing after careful examination. However, his spiritual beast, Ice Wind Python, transmitted a faint sense of fear from this place, probably due to the overwhelming demonic energy.

  Zhao Di absorbed all three Ice Demon Crystal Cores' magic with the Blood Devil Sword and fed them to the Frost Wind Python.

  Bingfeng Python swallowed four crystal nuclei rich in pure ice spirit energy in one breath, and its cultivation had already skyrocketed before it was fully refined. There were even signs that it was about to go into hibernation again to prepare for molting and advancing. Zhao Di didn't hesitate to recall Bingfeng Python back into the spiritual beast pouch.

  Without Ice Wind Python's help, Zhao Di would find it extremely difficult to gain anything else, so he simply returned to the edge of Cold Fragrance Spring.

  He let the Ice Wind Python meditate in the Cold Spring, using the Cold Spring to refine and transform the Ice Demon's Crystal Core, then set up a spell formation at the entrance of the cave to prevent anyone from entering.

  After doing all this, Zhao Di found a relatively flat place and sat down on the ground cross-legged.

  Two days later, it was the sixth day since he entered the Xuanhan realm. The Ice Wind Python had also fallen into a deep sleep in his spiritual beast bag.

  Zhao Di picked up the jade bottle that was still dripping with the Nine Cold Xuanming Water from under the stalactite, checked the amount of spiritual water inside with his divine sense, and revealed a satisfied expression before covering the bottle cap and putting it away in his storage bag.

  Then he put away the ritual tools under the array, took out the seal-releasing prohibition plate used to leave the sealed space, activated it, and prepared to leave this place and return to the Xuanzhou Immortal Island.

  If they wait another day, the cultivators who are still in the space will be sent back one by one, and the scene will definitely be chaotic. Especially those evil Dao cultivators who have gained nothing, may even become angry and take advantage of being in the territory of Xuanzhou Island to cause trouble. He doesn't want any accidents to happen because of this, it's better to lose that tiny bit of Jiuhuang Xuanming water.

  As for destroying the stalactites and making it impossible to continue forming Jiuhanyuanyang water, Zhao Di would never do such a thing. This kind of harming others without benefiting oneself is not his doing.
