Following the fluctuation of the spiritual energy, Lu Feng quickly entered the secret chamber and came to a shelf placed in the corner.
The shelves were divided into three layers, each containing only a few items.
The source of that Spiritual Qi fluctuation was a scale on the second floor.
Lu Feng recognized it at a glance. It was the reverse scale on the body of the dragon clan's ancestor, Yinglong.
"Yinglong, your painstaking efforts were in vain. You became Yellow Emperor Xuan Yuan's chariot and entered the Fire Cloud Palace to cultivate. However, your reverse scale was pulled out by someone and ended up in this different world."
Looking at that reverse scale, Lu Feng's eyes were a little blurry, and his thoughts seemed to once again return to the scenes of the Lich War.
It was after the Lich War that the humans took control of the world. The surviving Witch clan members were not willing to surrender and launched another war, resulting in the birth of the three Human Sovereigns, Fuxi, Shennong and Xuanyuan.
After each of them made their own contributions, the three Human Sovereigns entered the Fire Cloud Palace, which was 33 Layered Heavens, to study the Yellow Court's Scripture that the Daofather had passed on.
One of them, the Yellow Emperor, was someone who had defeated the Witch clan greatly and had done great deeds for the human race in order to be able to enter.
As for Yellow Emperor Xuan Yuan, when he flew to Fire Cloud Palace, he was riding the Dragon Clan's ancestor, the Raindragon. This was the origin for the humans to claim themselves as the descendants of dragons.
When humans ruled this world, Lu Feng had already died, leaving only a small remnant of his soul hidden inside the Primal Chaos Bell. However, this didn't mean that he was completely unaware of everything that was happening outside.
Of course, what caused Lu Feng to be moved was not the reverse scale of the Flying Rain-Dragon, but the almost completely dried up root beside it.
The root was about a foot long and completely black. It was dry and had a lot of mud stuck to it. If one looked closely, they would see that there was almost no spiritual energy fluctuating in the area.
However, with Lu Feng's knowledge, he was able to recognize the origin of this root with just a glance. It was one of the mysterious roots of heaven and earth – a small section of the Five Elements Spirit Fruit Tree.
Before the Primordial Era, before the opening of the universe, there was already a group of intelligent beings that had been infected with XianTian energy. Later on, they all became Xiantian Immortals, including Pangu, Taiyi, Nuwa, Qualified Apprentice, and other powerful beings.
Of course, the Upper Sky Realm warriors mentioned here were not the same as the Upper Sky warriors of the Tian Yuan Continent.
The 'Xiantian' of the Tian Yuan Continent only referred to the cultivators who had reached the independent circulation of their internal primeval essence, just like a fetus in its mother's womb. It was only a cultivation state.
And a first-rate Innate was the first life form born from the Primordial Purple Qi before the heavens and earth opened.
Since there were Xiantian Immortals in this world, there would naturally be Xiantian plants and ores. Many ancient Immortal artifacts were refined from the plant ores that had absorbed a sliver of Xiantian spiritual energy during the ancient era.
For example, the clear willow branches in the hands of the people from the Great Luo Golden Immortals' Passage, along with the Seven Treasures Wonderful Tree in the hands of the Daoist, were innate spirit plants that grew from the absorption of Spiritual Qi when the world first opened.
The Innate Spirit Plant was unlike any other immortal grass or treasure. It had all sorts of external appearances, and was like a supreme expert returning to its original nature. It was reserved and did not appear to be any different from any other plant.
The two most famous spiritual strains were the ginseng fruit tree that Zhenyanzi had taken away and the Immortality Peach tree that had fallen into the hands of the Jade Emperor Haotian. The wonders of these two trees were not described here.
The withered root in Lu Feng's hand came from the Five Elements Spirit Fruit Tree.
The Five Elements Spirit Fruit is no less miraculous than the Immortality Peach Tree. Every ten thousand years, only a batch of fruits can grow, absorb the spirit energy of the five elements, conceive of Yin and Yang, fuse Yin and Yang into chaos, and then produce a sliver of the origin energy of heaven and earth.
Moreover, the natural power nurtured within the fruit has incalculable benefits to the body's meridians.
Ever since the world started, the Five Elements Spirit Fruit had been kept in the hands of Nuwa, and she had spent the last nine days of her life carefully cultivating it. It was truly a precious treasure.
The only thing he did not know was how this piece of root, which was still stained with the Swelling Earth, had managed to make its way to the Tian Yuan Continent.
Lu Feng reached out and picked up the withered tree root. Feeling the faint life energy inside, Lu Feng couldn't help but be filled with emotion.
"Looks like after I left, my little junior sister encountered quite some trouble as well. Otherwise, how could the Five Elements Spirit Fruit tree that she'd always regarded as a treasure be destroyed by someone even the roots of a tree?"
Lu Feng's voice was barely audible as he mumbled to himself.
"Second Young Master, is there anything special about this tree root?" Lu Cheng asked curiously when he saw Lu Feng pick up the root.
Lu Feng fiddled with the root in his hand and said to Lu Cheng, "You have been guarding the treasury the entire time, but have you never heard of the legend regarding the root?"
Lu Cheng thought for a moment and said, "Second Young Master, I heard from my grandfather that he was also a guard at the treasury back then.
According to him, this root had been here since a long time ago. Although he couldn't feel any spirit energy fluctuations from it, what was strange was that even though this root looked very dry, it actually couldn't be cut or cut at all. Even when his family took the initiative to use a Profound Grade spirit artifact, it still couldn't harm it at all.
Even more bizarre was that the soil on top of it was just like the soil on top of it. No matter how one looked at it, it was impossible to get it off.
Back then, the clan head had specially ordered for this item to be stored in a secret room, waiting for the arrival of a fated person.
Second Young Master, do you know where this thing came from? "
"Hehe, how would I know its origin?"
As Lu Feng spoke, he casually put the root back to its original flavor.
Lu Feng looked at the treasures in the secret chamber and left empty-handed. In his words, although those items were not bad, they were of no use to him at the current stage.
Of course, it was impossible for Lu Feng to tell Lu Cheng that he was determined to obtain the Five Elements Spirit Fruit's roots. It was just that it was temporarily left there since it was useless right now.
After leaving the treasury, Lu Feng went straight to find the family's guard commander, Lu Wenshan.
Lu Wenshan looked like a middle-aged man with a middle stage Xiantian cultivation. He was one of the elite warriors from the Lu family who had followed Lu Kun to kill the leader of the Magic Beasts.
Lu Wenshan had always been loyal to the Lu Family, and his position in the family was also very important.
After Lu Feng told Lu Wenshan the purpose of his visit, Lu Wenshan happily agreed to arrange a few personal guards for Lu Feng. As the second young master of the Lu family, this was also the treatment Lu Feng was supposed to enjoy.
Just like this, Lu Cheng was successfully assigned to Lu Feng's side. He became Lu Feng's personal bodyguard leader, and together with a few other bodyguards, took on the responsibility of protecting Lu Feng.
After fulfilling his promise to Lu Cheng, Lu Feng returned to his own courtyard and started considering the matter of refining pills.
