The Longevity Family: Starting from the Foundation Establishment Ancestor

Holding the Underworld King Seal, Han Mu transformed into a streak of light and sped through the Netherworld Cave passage. Behind him came Xue Li's furious roar, but he was quickly left behind. With the Underworld King Seal in hand, he could sense some of the restrictions within the Netherworld Cave, easily avoiding traps along the way, his speed far surpassing that of Xue Li and the others.

"Youngster, leave behind the Underworld King's Seal, and I'll spare your life!" Xue Li's voice came from behind, growing ever closer. This old demon had clearly used some kind of secret technique, his speed increasing dramatically.

Without turning his head, Han Mu unleashed a burst of Primordial Chaos Sword Qi. The sword qi transformed into a five-colored rainbow, shooting straight at Xue Li. Xue Li swung his sword to block, but the power of the five elements contained in the sword qi caused his blood and qi to churn, and his speed was momentarily halted.

"This kid has been hiding his true strength!" Xue Li was shocked. The power of that sword strike was no less than that of a late-stage Nascent Soul cultivator, and perhaps even stronger. Could this person really be a Void Refinement cultivator in disguise?

"Bloodthirsty Fierce, stop chasing! Deal with this first!" Ghostly voice came from behind, filled with anxiety. Inside the Underworld Palace, the twelve Underworld Generals and the three coffin-bound warriors had fully awakened, and the three forces were locked in a fierce battle, suffering heavy casualties.

Xue Li gritted his teeth, glanced in the direction Han Mu had disappeared, and finally turned back. The Underworld King's Seal was good, but if all his subordinates died, he would be all alone, which would be a loss.

Han Mu sensed the bloodthirst receding and breathed a sigh of relief. Although he wasn't afraid, it was good to save some trouble. He quickened his pace and, half an hour later, rushed out of the Netherworld Cave entrance.

Chaos had broken out outside the entrance. Some cultivators who hadn't been able to enter the core area were exploring the perimeter, while others were waiting. They all looked at Han Mu with surprise when he suddenly rushed out. Han Mu ignored them and transformed into a beam of light, disappearing into the distance.

"Who is that person? Why is he out alone?"

"What he's holding... looks like the Seal of Hades!"

"What? The Underworld King's Seal has been stolen? Quickly, notify the sect!"

The news spread quickly, and the various forces remaining outside set off one after another. Some went to report the news, while others tried to track down Han Mu, but Han Mu was too fast and soon disappeared into the gray fog.

Leaving the Netherworld Mountains, Han Mu reverted to his original appearance, removed his disguise, and his aura returned to that of the "Early Nascent Soul Stage." He examined the Netherworld King Seal in his hand. This seal was palm-sized, entirely black, and covered with Netherworld runes, emanating a dense aura of death. The bottom of the seal was inscribed with four ancient seal characters: Netherworld King Suppresses Prison.

"It really is the Underworld King's Seal, capable of controlling part of the restrictions in the Netherworld Cave." Han Mu channeled his magic power, and the Underworld King's Seal glowed faintly. He could clearly sense the situation inside the Netherworld Cave. At this moment, the cave was in complete chaos, with the three forces clashing with the Underworld Generals and War Generals, resulting in more than half of them being killed or wounded. Although Blood Fiend, Ghost Shadow, and the Gray-Robed Man were all formidable, they were struggling to cope with the immortal Underworld Generals and Nascent Soul War Generals.

"It seems they won't be coming out anytime soon." Han Mu put away the Underworld King Seal and flew towards Han City. He had achieved his goal for this trip, not only thwarting the conspiracy of the Blood Demon Sect and the Samsara Palace, but also obtaining a treasure like the Underworld King Seal. He had gained a great deal.

Five days later, Hancheng will be in sight.

Han Mu returned directly to the city lord's mansion without alerting the guards. Han Changqing, Han Li, and the others sensed his return and rushed over.

"Father, did the trip go smoothly?" Han Changqing asked.

"Not bad." Han Mu took out the Underworld King Seal. "This was obtained from the Netherworld Cave. The Underworld King Seal can control part of the restrictions in the Netherworld Cave. In the future, Han City can send people in to explore regularly, and the gains will not be small."

"The Seal of the Underworld King!" Han Li was moved. He had lived in the Spirit Realm for many years and had naturally heard of the seal's great name, but he never expected that Han Mu would seize it.

"In addition, I also bid for three outer perimeter tokens of the Guanghan Realm." Han Mu took out three more silver tokens. "Adding the two slots given by the Alliance, Han City can send five people in this time. Han Li, Han Yunge, Han Jinglei, and Han Ling'er, the four of you are already decided. For the last token, you can discuss and see who is suitable to give it to."

"Ancestor, I think we can give it to Han Tianfeng," Han Yunge suggested. "He has awakened the Wind Spirit Root and his cultivation has reached the mid-stage of Core Formation. He may have opportunities in the Guanghan Realm. Moreover, he has a calm and steady personality and can be of great use."

"Han Tianfeng..." Han Mu pondered. This young man was indeed excellent, one of the best among the second batch of bloodline awakeners. "Alright, he's the one. Han Li, you're in charge of guiding the five of them, practicing their teamwork, and making sure they form combat power before entering."

"Yes," Han Li replied.

"Furthermore, I've received news that the Blood Demon Sect, Shadow Assassin Hall, and Samsara Hall suffered heavy losses in the Netherworld Cave and are unable to retaliate in the short term. However, we must be wary of them secretly plotting against us," Han Mu said. "Changqing, strengthen the security in Han City, especially with the Guanghan Realm about to open; don't let them take advantage of any loopholes."

"Understood." Han Changqing nodded.

"Yun Ge, how's the preparation of the elixirs going?"

"Reporting to Ancestor, the auxiliary ingredients needed for the Moonflower Pill have been prepared, only the main ingredient, the Moonflower Lotus, is missing. In addition, various healing, recovery, and detoxification pills have also been refined in sufficient quantities, enough for five people to use for three years," Han Yunge reported.

"Good." Han Mu was satisfied. "Han Li, take them to familiarize themselves with the Lesser Five Elements Battle Formation. Five people per group, just right for setting up the formation. The Guanghan Realm is fraught with danger, and with the protection of the battle formation, it will be much safer."

"I'll go right away." Han Li accepted the order and led Han Yunge and the others away.

After everyone left, Han Mu went to the secret chamber alone. He took out the Underworld King Seal and began to refine it. Although this seal was a treasure of the Underworld, it had been purified by the system and was no longer susceptible to the corrosive effects of death energy. After refining it, he would not only be able to control the restrictions of the Netherworld Cave, but also be able to cultivate with the power of the Underworld, which would also benefit the "Primordial Longevity Technique".

Three days later, the Underworld King Seal was completed. Han Mu probed into the cave with his divine sense and could clearly perceive everything inside. At this time, the battle inside the cave was nearing its end. More than 80% of the three forces had been killed or wounded. Blood Fiend, Ghost Shadow, and the Gray-Robed Man each led their remaining troops to the vicinity of the entrance, preparing to evacuate. The Twelve Underworld Generals and the three warriors had also suffered considerable losses and retreated to the Underworld King's Palace to rest.

"After this battle, the Blood Demon Sect and the Shadow Killing Hall have suffered heavy losses and are no longer able to plot against the Netherworld Cave in the short term." Han Mu withdrew his divine sense. "As for my Han City, we can take advantage of the Netherworld King Seal to explore it regularly and reap resources."

He then checked the current state of Hancheng. The Bloodline Awakening Pool had been operating for several months, and more than ten members of the Han family had awakened special spiritual roots or physiques, including two with Heavenly Spiritual Roots, possessing immense potential. The total number of cultivators in Hancheng had exceeded five thousand, with the number of Nascent Soul cultivators increasing to fifteen, Core Formation cultivators exceeding two hundred, and Foundation Establishment cultivators approaching one thousand.

"System, check the task progress."

[Current Task: Develop Hancheng (In Progress)]

[Task Progress: Nascent Soul Cultivator 1/10, Intermediate Advancement (85%)]

[Requirements for advancing to a higher-level stronghold: ≥10 Nascent Soul cultivators, ≥30 Core Formation cultivators, 1 medium-sized spiritual vein, and 1 completed large-scale mission]

Current contribution points: 22000

"Promotion progress 85%, still 15% short," Han Mu pondered. Large-scale missions could include the trip to the Netherworld Cave, medium-sized spiritual veins… Han City currently only has small spiritual veins, which need to be found or cultivated.

"System, exchange for the 'Spirit Vein Advancement Method'." He thought of the Star Stone, which contained the power of stars and could help advance the spirit vein.

[Exchange for the Spirit Vein Upgrade Method requires 5000 Contribution Points]

[Redeem or not?]

"exchange."

[Exchange successful, 5000 contribution points consumed]

[Remaining Contribution Points: 17000]

A jade slip appeared in Han Mu's hand. He probed it with his divine sense and found a method for upgrading a small spiritual vein to a medium-sized one, using a star stone as the core and supplemented with various spiritual materials. The success rate was 70%, and the process would take three months.

"Perfect timing. There's still a month and a half until the Guanghan Realm opens, enough time to complete the upgrade before entering." Han Mu noted down the required materials. Most of them were available in the Han City warehouse, and the few missing items could be purchased or exchanged.

He summoned Han Changqing and handed him the list: "Gather these materials as soon as possible. I need to upgrade the spiritual vein of Han City. This matter must be carried out in secrecy; do not let anyone know."

"Yes!" Han Changqing took the list and left in a hurry.

Han Mu then arrived at the backyard of the City Lord's Mansion, beside the Bloodline Awakening Pool. Golden light swirled within the pool, where over thirty members of the Han family had already awakened their bloodlines, with remarkable results. He took out the Underworld King Seal, from which a wisp of pure Netherworld Qi flew and was cast into the pool. The Netherworld Qi fused with the spiritual liquid in the pool, transforming into a pale gray color, gaining a more mystical quality.

"Adding Netherworld energy can help disciples comprehend the laws of life and death, greatly benefiting their mental cultivation," Han Mu nodded. The Netherworld King Seal was indeed incredibly useful.

A month later, the Han City spiritual vein upgrade was completed. The original small spiritual vein expanded three times in size, and the concentration of spiritual energy increased by 50%, barely reaching the standard of a medium-sized spiritual vein. The cultivation speed of Han City cultivators increased significantly, and the chances of breaking through bottlenecks also improved considerably.

The day when the Moon Realm opens is also just around the corner.
