After leaving the Myriad of Techniques, Yuan immediately began making his way back to the Nameless Emperor's Tomb.
On his way there, he would think about the new cultivation technique that he'd just acquired.
<Heaven's Indomitable Soul>
<Rank: ???>
<Mastery Level: ???>
<Description: A technique of unknown origins. Absorb the very essence of this world and convert it into your Soul Strength.>
As he couldn't wait to experience the technique, Yuan decided to use the technique while he was on the move to see how it worked.
Immediately after he activated the technique, Yuan could feel his body absorbing the spiritual essence around him, almost like how cultivators absorb Qi when they cultivate. However, spiritual essence was different from spiritual energy.
Unlike spiritual energy that will inevitably have impurity, spiritual essence is completely pure, so the cultivator won't need to cleanse its purity after absorbing.
Furthermore, spiritual essence itself is much stronger than spiritual energy, making it the ideal resource for all cultivators. However, one does not simply cultivate spiritual essence normally.
In order to absorb spiritual essence, one must be able to sense spiritual essence, something that is only doable after they become an immortal.
In other words, Yuan, who was still a mere Spirit King, could absorb spiritual essence and achieve what even immortals find difficult. That's not all. Not only could he absorb spiritual essence, but he can even convert it into his soul strength, something only those that have learned Heaven's Indomitable Soul technique could achieve.
There is even a popular saying in the Supreme Heavens that says a single drop of spiritual essence is more valuable than a whole sea of spiritual energy, as spiritual energy essentially becomes useless to Immortals, who can only grow through spiritual essence.
Yuan could feel an overwhelming feeling suddenly wash over him, almost like a pillar in the middle of the ocean, where the water would continuously refresh his body, mind, and soul.
<+2,021 Soul Strength>
<+3,000 Soul Strength>
<+2,391 Soul Strength>
Every few seconds, his Soul Strength would increase by the thousands. If the world knew of this, they would surely be shocked to death.
'My divine sense is expanding at a ludicrous rate…' Yuan thought to himself as his divine sense reaches over 100 miles, and it was still growing with every passing second.
Xiao Hua could sense something was going on around Yuan even though she couldn't sense spiritual essence.
"Brother Yuan, are you okay?" She asked him.
"Yes, I am just testing out the new soul cultivation technique. It's quite powerful. My Soul Strength is increasing by the second."
"What kind of effect does it have?" Feng Yuxiang asked out of curiosity.
"It absorbs spiritual essence and converts them into my Soul Strength."
"What?! You can absorb spiritual essence already?!" Unsurprisingly, Feng Yuxiang exclaimed in a shocked voice after hearing this information.
"Only those that have succeeded their Immortal Ascension should be able to do such a thing!"
Out of everything Yuan has done up to this point, his ability to absorb spiritual essence as a mere Spirit King was the most shocking by far, not to mention that he could even convert it into Soul Strength.
For comparison, it was akin to a mortal learning cultivation techniques only comprehensible by gods, or a mortal casually wielding a godly artifact that would normally kill anyone that isn't powerful enough to wield it.
"Yuan… You should keep this information a secret." Lan Yingying suddenly spoke in a worried voice.
"She's right, Brother Yuan. If the world knew, all of the powerful cultivators out there would definitely try to kill you because of your potential, especially Immortals, who would be filled with jealousy and anger if they knew that a Spirit King could use their spiritual essence." Xiao Hua said.
Most Immortals consider the ability to absorb spiritual essence an honor— something they had to shed blood and tears for thousands of years to acquire, yet Yuan, who wasn't even a hundred years old, could use it. His existence was offensive in itself to these Immortals.
By the time Yuan returned to the Nameless Emperor's Tomb, his Soul Strength has increased by over 10 million.
To put into perspective how much that is— even Spirit Sovereigns wouldn't have a third of that.
At his level, his divine sense could cover over a thousand miles with ease, and he could even keep it active for weeks without any breaks.
In fact, even if they had a powerful soul cultivation technique, it would take most cultivators over a hundred years to amass 10 million Soul Strength, something Yuan achieved in a few mere hours.
'It's been a week since the Nameless Emperor's Tomb opened, but it's still as crowded as the first day.' Yuan thought to himself as he was surrounded by people.
And because there were so many people, the entrance was blocked by the Ji Family, as they were controlling the amount of people entering at a time.
[If you wish to enter the Nameless Emperor's Tomb as a rogue cultivator, you must pay a fee of 1,000 spirit stones!]
These words were written on a large banner that hung above the tomb.
"The hell? We have to pay to enter? And a thousand spirit stones… That seems a bit too excessive." Yuan was speechless.
"This is how they keep the tomb from being overflowing with people. Though, this will only apply to rogue cultivators. All disciples and members of big families will still be allowed to enter for free, and since you're a Spirit King, you should also be able to enter without needing to pay." Feng Yuxiang said.
Sometime later, Yuan approached the entrance while wearing the Jade Sword Manor's guest robe.
When the Ji Family saw his clothes and sensed that he was a peak Spirit King, they allowed him to enter the tomb without any troubles.
"Best of luck to you, Senior." The members of the Ji Family mistook Yuan as a senior who was disguised as a young man due to his cultivation base.
Yuan didn't bother trying to correct them and proceeded towards the portal, stepping inside the Nameless Emperor's Tomb a moment later.
