For example, entrusting the Primordial Spirit Brand, or using the power of the Fire Cloud Cave to suppress one’s own fortune.
The Primordial Spirit Brand is entrusted here, protected by the Saints of the Fire Cloud Cave. Even if killed, one can be reborn through this Primordial Spirit Brand.
No matter how formidable the enemy, none would dare commit the great offense of the world by breaking into the Fire Cloud Cave and extinguishing the Primordial Spirit Brand left by the Ancient Saint King.
The second function is even more mysterious.
Fortune is exceedingly mysterious; even if great fortune converges, without a supreme treasure to suppress it, fortune will eventually leak away, much like a mortal’s lifespan, ebbing away gradually.
Only with a supreme treasure can it be slowed down, or even completely suppressed.
The Fire Cloud Cave is a sacred land of the Human Race, and one can use the Cave’s power to suppress one’s own fortune to slow its loss.
Yet Zhang Jian could imagine that having gained benefits from the Fire Cloud Cave, he would surely have to repay more in the future.
He is, after all, at the core of the Tongshan Dao Lineage.
The Tongshan Dao Lineage is also a central part of the Three Emperors and Five Elders Assembly; he was naturally marked by it from birth, so a little more or less does not matter to him.
Lingering before this holy temple for a moment, Zhang Jian no longer hesitated, casually sending a trace of Primordial Spirit Brand into it.
The Red Dragon Pearl in his hand was left with Zhang Zhao and his wife to suppress the national fortune, as it was necessary to have a supreme treasure to suppress the Human Emperor’s great fortune and slow its loss.
Immediately, Zhang Jian set his gaze on the Fire Cloud Cave Mansion deep within the sea of clouds.
He directly flew back into the sea of clouds, slowly stepping into the Fire Cloud Cave Mansion.
As soon as he entered the Fire Cloud Cave Mansion, Zhang Jian sensed a figure waiting there for him.
Clad in a Fire Cloud Robe, surrounded by fiery red divine light, he stood at the entrance of the Fire Cloud Cave Mansion.
"Fellow Daoist Hongyun?"
Zhang Jian blinked.
Hongyun’s expression was indifferent, and he spoke mechanically:
"Fellow Daoist Zhang, there are four layers of Fire Cloud Wall in the inner layer. Each time you break through a layer, you will gain an additional eight hundred years of stay. If you manage to break through all four layers, it naturally means you have the qualifications to enter the core depths of the Fire Cloud Grotto Heaven to cultivate!"
"Qualifications?"
Zhang Jian’s eyebrows moved; he noticed the emphasis in Hongyun Daoist’s words.
Hongyun Daoist nodded slightly and said no more.
"As a reward for repairing the Great Circulation Celestial Red Cloud Forbidden Technique in the outer layer, this deity reminds you that the core of the inner layer is the absolute inheritance for sages!"
With these words, he vanished into thin air like a bubble from the mansion.
Zhang Jian was slightly taken aback.
It seemed that repairing that Great Circulation Celestial Red Cloud Forbidden Technique in the outer layer had extra rewards.
He chuckled slightly and soon turned his eyes forward.
What unfolded before him was a vast valley.
The cave mansion revealed another world!
This valley was extremely expansive.
It resembled a primeval forest grotto heaven, surrounded by medicinal gardens and orchards.
In the distance, the mountains were like ocean peaks, one after another, displaying a grand and magnificent wilderness aura coming towards him.
Zhang Jian noticed that the surrounding medicinal gardens were meticulously maintained, clearly by someone who attended to them regularly.
The gardens were filled with all sorts of incredibly rare herbs, each arranged according to their growing environment, thriving in patches of nine-colored soil.
Deep within this nine-colored soil, each color contained a different earth attribute, either warm or cold, full of light or shrouded in dark silence, and even extreme environmental conditions were present.
The herbs growing within were completely diverse; among them were exquisite varieties, some having grown over tens of thousands of years, as immortal plants.
Zhang Jian, for instance, saw a herb named Immortal Grass within, containing the mysteries of longevity.
There were also other supplements like ginseng, Spiritual Wisdom, and Yellow Essence that had grown for over ten thousand years, in much greater quantity.
At the deeper end of the valley stood several elegant pavilions. As Zhang Jian looked, he first noticed a pharmacy rich in medicinal aroma. He stepped inside to find a large pharmacy, with many medicine cabinets filled with remaining medicinal materials.
Beside it was the Alchemy Room.
In the center of the Alchemy Room was a large cauldron. Although the flames beneath it had gone out, Zhang Jian could still smell their scent.
Watching this scene, Zhang Jian felt a tinge of helplessness.
Unfortunately, he wasn’t very adept at alchemy, so even having entered this treasure land, he was unable to fully exploit it.
At this time, his gaze turned towards the center of the room,
Where there were two celestial Dao Talismans that seemed as if the path of heaven and earth had descended.
"Heaven and Earth!"
With just a glance, Zhang Jian felt as though he was immersed in the depths of the Great Dao of Heaven and Earth. Innumerable profound mysteries of the heavenly and earthly Dao Laws were contained within, causing his eyes to emanate intense divine light.
The words ’Heaven and Earth’ before him seemed to have been naturally formed at the dawn of creation, embodying endless mysteries.
Having achieved Dao Fruit through the Path of Sheji, Zhang Jian vaguely felt that if he could comprehend the mysteries of these words, his Earth Emperor Dao Qi would advance significantly.
However, Zhang Jian did not directly try to comprehend it. Instead, he planned to explore the surroundings first, find the first Fire Cloud Wall, and then return to comprehend the ’Heaven and Earth’ mysteries!
Not long after, Zhang Jian returned.
This seemed to be the Agricultural Emperor’s Residence. Besides the medicinal gardens and the Alchemy Room, there was also a Library.
The Library was filled with various ancient texts, and many classics were recorded in the Dragon and Phoenix Treasure Talisman, which for Zhang Jian was also a treasure vault.
He had already found the first Fire Cloud Wall.
It was deep in the valley.
The method to pass through the Fire Cloud Wall was simple: leave behind a self-created Tier Four Immortal Technique for later generations to appreciate.
