Becoming an immortal and ancestor begins with the golden toad spitting out money.

Having gained valuable experience from the successful Bright Moon Wonderland Project, Su Ji was still feeling his way forward when it came to advancing in the Golden Cave Wonderland.

After all, ordinary blessed lands at most involve the five elements, but the blessed lands of the Golden Cave Sect involve various earthly evil forces.

Earthly Fiends and Heavenly Gangs are two natural energies that exist between heaven and earth. They are mutually opposed yet naturally coordinated. Although they can be simply compared to Yin and Yang, they are far more complex than Yin and Yang.

Not long ago, Su Ji had a duel with Ji Ren, a ghost general of the Taiyin Sect. The reason why even the Heavenly Thunder of Qiankun could not penetrate the opponent's Taiyin Immortal Body was not only due to the power of Taiyin and the power of the Earth Ghost, but also because of the power of the Heavenly Gang and Earthly Fiend contained within.

The Heavenly Stems and Earthly Fiends do not necessarily need to be balanced, but they must be coordinated. Letting them run wild will only produce more chaotic energy. They also need a carrier to minimize the side effects of the energy.

The carrier of evil energy is naturally related to the earth's veins. Su Ji also plans to use five minor immortal fruits as carriers and, through the mutual generation of the five elements, completely transform these powers into a part of the Golden Cave Immortal Realm.

As for the carrier of the Qi, Su Ji had some ideas based on the information he had collected.

The Qi must be combined with the Wind Eye Immortal Aperture, and then, with the East Sea Immortal Lord, the North Sea Snake Clan Little Immortal, the Fengshan Tiger Clan Little Immortal and the Wind and Fire Small World Dao Fruit he controls as the core, these powers are transformed into a part of the blessed land through the rotation of the Four Symbols.

Regarding the important matter of advancing in the Golden Cave Immortal Realm, even though some minor immortals had strong opinions, they quickly accepted other forms of compensation after Su Ji returned to the Golden Cave Sect; otherwise, they might have been replaced.

During the setup process, the five elements of evil energy quickly and successfully integrated into the five small world fruits, giving the will of the Golden Cave Immortal Realm the ability to devour the power of the Undying Demon Lord below.

However, since Su Ji's Four Symbols Qi Formation was not yet fully constructed, the will of the Golden Cave Immortal Realm could only temporarily absorb the evil energy between heaven and earth.

The will of the Golden Cave Wonderland was cooperative, after all, Su Ji had already given a guarantee that the plan to absorb the power of the Undying Demon Lord would be launched no later than the next winter, which would take nine to twelve months.

Thus, Su Ji resided in the Golden Cave Wonderland for a long time, only stopping by Jinfeng County to check on the progress of the Great Sun Wonderland project when he went to the Taiyin Star Dojo.

After the New Year, spring arrives as the ice and snow melt away.

As all things revive, Su Ji carefully comprehends the differences between the Four Symbols Qi Array and heaven and earth, and perceives the profound mystery of the birth of young yang from the changes between winter and spring.

At this time, Dongsang and Xisang villages were thriving. Thanks to the construction efforts of the East and West Chambers of Commerce over the past few years, most of the houses in Dongsang and Xisang villages had been replaced with brick and tile houses, and the dirt roads had been transformed into cinder roads. When it rained, people no longer had to worry about getting stuck in the mud.

As the waterwheel slowly turned, the still-chilly river water flowed into the fishpond, and the mulberry trees covering the mountains and fields gradually sprouted patches of emerald green.

Just as the people were preparing for spring plowing, news of a new war suddenly arrived from the imperial court.

It turns out that there were few battles in the western border region during the winter due to the cold climate. But now that spring has arrived, the foreign tribes in the frigid northwest can no longer hold back and have joined forces with the foreign tribes in the western border region to burn, kill, and plunder.

The so-called alien races included not only the demon race and the witch race that had always retained their ancient god beliefs, but also some human races that had been exiled to the frontier.

The sudden attack by the foreign tribes caught the border soldiers off guard, and the extended battle lines made it difficult for them to achieve significant results in their encirclement and suppression efforts.

Not long after, a general suddenly became famous for his many meritorious deeds. He was none other than Li Hui, who had the East-West Chamber of Commerce as his backer.

In such a protracted war, large-scale battles are rare, and Li Hui's army of one or two hundred men actually possesses excellent mobility.

With the logistical support of the East-West Chamber of Commerce, Li Hui not only led his soldiers to relieve the siege of border cities on multiple occasions, but also used the natural terrain to ambush and kill the plundering foreign army, achieving excellent results. Soon, many generals learned Li Hui's fighting style. Some achieved some success, while others fell into traps set by the foreign tribes, and some almost died in the frontier wilderness due to logistical difficulties.

The border wars also temporarily eased the conflict between the Western Emperor and the Southern Emperor.

The Southern Emperor was pleased with this arrangement, for only when the Western Emperor's strength was depleted by border wars could he wait in comfort to unify the world in the future.

Soon, spring turned to summer, and the last vestiges of spring chill were dispelled by the sunshine. The melting snow and ice in the border mountains turned into rushing rivers, nourishing the earth.

Suddenly, a large army of foreign tribes marched south from the northern frontier. They quickly occupied many counties and used this as leverage to demand compensation from the imperial court.

The Southern Emperor claimed to be the rightful ruler of the land and had no intention of paying compensation. However, the actions of the foreign tribes soon shocked the world.

The entire county was slaughtered by the foreign tribes, and when the soldiers from the northern frontier arrived, in addition to mountains of corpses and seas of blood, there were also mounds of heads made up of human heads.

The whole country was shaken. Many officials proposed to go north and wipe out the foreign tribes, while others were terrified by the cruelty of the foreign tribes and wanted to compromise by paying compensation.

The Southern Emperor and the Prince of Fu were worried that going north would leave the capital vulnerable and be taken advantage of by the Western Emperor, so they only ordered the soldiers in the northern frontier to fight against the foreign tribes.

As a result, the northern barbarians quickly occupied many areas and used the natural defenses of the northern mountains to fight against the northern soldiers. By autumn, one prefecture had already fallen.

The Southern Emperor's weak actions were despised by the people, while the Northern soldiers became even more valiant, firmly holding the front line and seeking opportunities to break through natural barriers to recover lost territories.

Among them, the Marquis of Beihe was the most valiant. He actually charged into the camp of the northern barbarians before the heavy snow blocked the mountains, killed more than a dozen northern barbarian generals, and annihilated three or four thousand enemies.

After this victory, the people of the world applauded and cheered. The Southern Emperor also lavishly rewarded the Marquis of Beihe and bestowed upon him the title of General Who Guards the North.

As the weather gradually turned colder and snow began to fall in northern Xinjiang, the fighting entered a period of relative calm.

At the foot of Jushan Mountain, where Yuzhou and Lunzhou meet, Su Ji experienced the cycle of winter, spring, summer, autumn and winter. With the help of the operation of the Four Symbols Qi Array in the Golden Cave Wonderland, he finally comprehended the Four Symbols Cycle [Root Method].

At this point, Su Ji only needs four of the nine [root methods] required to pave the way to sainthood: Yin-Yang Harmony, Four Symbols Natural Formation, Four Symbols Yin-Yang, and Five Elements Yin-Yang.

At the same time, the Four Symbols Qi Array of the Golden Cave Wonderland finally reached harmony with the Five Elements Evil Qi Array, and the Golden Cave Wonderland could finally absorb the power of the Undying Demon Lord without too many worries.

Taking advantage of the temporary lull in the war due to winter and the relatively weak power of the Undying Demon Lord, Su Ji, with the assistance of the Heavenly Court's immortals and gods, officially began his plan to advance to the Golden Cave Immortal Realm.

"Golden Cave Immortal Realm's will prevails. The Qi and Sha have now achieved harmony through the Five Elements and Four Symbols Formation. Please immediately absorb the power of the Undying Demon Lord!"

The Golden Cave Wonderland was originally a medium-level blessed land, but it fell in level due to the external refinement and internal invasion of the Undying Demon Lord. Now, it is absorbing the power of the Undying Demon Lord in return. Even if it is promoted to a medium-level blessed land, it will only be a temporary recovery of its investment.

Su Ji had an even bigger plan: to use the Undying Demon Lord as a "power bank," so that one day he could upgrade the Golden Cave Wonderland to a high-level blessed land! (End of Chapter)
