Yet earlier, he had definitely not noticed the presence of this golden energy?
He thought of something and looked toward the Longevity Technique,
[Longevity Technique (Water): Perfection (Cannot be Enhanced), Traits: Longevity 5th Level, Art of Staying Young 5th Level, Strengthening the Foundation and Nourishing the Essence 4th Level, All Rivers Flow into the Sea 3rd Level, Innate Body, Unity of Heaven and Man 1st Level]
[Unity of Heaven and Man: Can discover more refined primordial energy between heaven and earth, and each level up of the skill doubles the absorption speed of primordial energy.]
"More refined primordial energy."
Chen Fan realized.
He looked up at the sky again and saw those strands of golden energy floating.
It seems that the reason for the previous growth of Primordial True Essence by two points is due to absorbing these strands of golden energy.
They exist between heaven and earth, but his sensitivity to primordial energy was too low to detect their presence. He blindly absorbed them with the white ordinary energy into his body.
"So, it means that there are even more refined primordial energies in this world."
Chen Fan pondered.
Then, he closed his eyes again to absorb the few strands of golden energy.
In the next moment, the Primordial True Essence in his body increased by 4 points! While the consumption of Spiritual Power remained unchanged.
Chen Fan did not stop and absorbed all the remaining strands of golden energy into his body, so that no golden energy could be seen around anymore.
The growth rate of the Primordial True Essence inside him also dropped from 4 points per second to 2 points.
"Not bad."
Chen Fan thought to himself.
Even refining elixirs to convert into potential points does not have such a fast growth rate.
As long as Spiritual Power was sufficient, he could keep absorbing endlessly.
A few minutes passed, and his Spiritual Power reached its limit. Chen Fan finally felt the long-lost sense of fatigue, as sleepiness swept over him.
He yawned, showing a look of lingering interest on his face.
In less than ten minutes, the Primordial True Essence in his body increased by three to four hundred points. This speed is almost catching up with the Star Absorption Technique.
Moreover, he discovered a point that not only the white primordial energy but also the golden primordial energy seemed to be endless.
Though not as abundant as the former, it appeared occasionally, and whenever it did, he would prioritize absorbing the golden energy before the white primordial energy.
"Exchanging the Observing the Universe Technique earlier was indeed a wise choice."
Chen Fan mused.
Once the Observing the Universe Technique was cultivated to its highest realm and Spiritual Power broke ten million points, that would be indisputable.
By then, his absorption of primordial energy would last longer, and his strength would increase faster.
Additionally, he should find a way to obtain the remaining Chapters of the Longevity Technique.
Even a single Chapter brought such significant improvement. If he collected them all, the result would be unimaginable.
Chen Fan’s lips curved upward, as he sat down again and entered meditation.
Now was not the time to sleep. After meditating for a few hours to replenish Spiritual Power, he needed to continue absorbing primordial energy.
One night passed quickly, and dawn broke with a touch of white.
Sitting on the sofa, Chen Fan slowly opened his eyes.
Throughout the night, he meditated twice and absorbed primordial energy three times, causing the Primordial True Essence in his body to increase by nearly 1500 points, almost doubling.
There were notable changes in his panel values.
Realm: True Essence Realm·Second Realm (1.85%) (+)
True Essence: 221748/3304.75 (+6710%)
Level: 29 (0/1 billion)
Constitution: 331900

Agility: 61600

On the city walls, guards stood in a state of high alert, gripping their weapons tightly.
Some used the large telescopes on the walls to scan the horizon, letting out sighs of relief upon not spotting the beast tide but quickly turning anxious again, repeating the cycle.
Time ticked by steadily, and figures began to appear outside the city.
They looked ragged, some wounded, walking step by step towards the city, faces filled with fear and a hint of hope.
Among them was an old man, blending with the crowd, who looked up at the city before him, silently musing, this is Anshan City? Surrounded by mountains on three sides, it indeed was easy to defend and hard to attack.
Yet that young fellow Chen underestimated the beast tide.
The crowd reached the outskirts of the city, uttering cries of plea.
To their surprise, the city gates opened, and the guards, contrary to the expected arrogance, politely registered each person and let them in.
"Old man, did you come here alone?" someone asked Elder Wang in astonishment.
"Yes," Elder Wang smiled wryly, "Luck was on my side, I didn’t encounter any fierce beasts. Maybe they saw my old bones and decided to spare me."
"What a stroke of luck."
The guard sighed, then addressed the crowd, "You have come at the right time. After today, entering the city will be difficult."
The crowd exchanged glances and thought about the perils they had faced on the way.
"The beast tide is about to erupt."
The guard sighed, "Possibly within these two or three days, by then, the area outside the city will be filled with fierce beasts, and none of us will be able to leave."
"!!!"
The crowd revealed expressions of shock.
Beast tide? Is it true?
"Hey, big brother, is the beast tide really about to erupt?" someone asked with disbelief.
"I wish it were false, but it’s the City Lord’s Mansion’s notice. The awakeners wouldn’t joke about this."
The guard sighed, then waved his hand to urge, "Alright, those who have registered, hurry inside. Behave and don’t cause trouble. Even if the beast tide erupts, no one will expel you."
