Two months later, Liu Yi looked at the energy storage device in front of him with a satisfied smile on his face.
Drawing inspiration from the Sun Swallowing Art and using the concept of Yin and Yang Rotation, he finally created an Energy Conversion Formation after hundreds of deductions and experiments.
This Formation can convert solar energy, Lunar Essence, and Starlight into gentle energy.
Now, he has refined this Formation into the energy storage device, creating the brand-new energy storage device before him.
He placed the energy storage device under the sun.
The solar energy from heaven and earth slowly converged toward the energy storage device, flowing into it along the Dao Patterns on its surface.
An hour later, Liu Yi picked up the energy storage device and circulated his technique to absorb the energy inside.
A surge of energy, gentler than raw solar energy but more explosive than Heaven and Earth Spiritual Qi, flooded into his body and was quickly refined.
"Initial success; it's usable now. However, I'll need to continue improving it later." He stroked his chin, lost in thought.
"Solar energy converted by the energy storage device becomes gentler and easier to absorb, while still retaining its original purity."
"I need to prepare several more energy storage devices to serve as energy sources for my Breakthrough to the Foundation Establishment Realm. Otherwise, it'll be troublesome if I don't have enough energy for the Breakthrough when the time comes."
Currently, Liu Yi has polished his Qi Refining Realm cultivation to the limit and can break through to the Foundation Establishment Realm at any time.
Seven days later, Liu Yi sat cross-legged in the center of the courtyard, with the last 20 Mid-Grade Spirit Stones and 100 energy storage devices filled with energy neatly arranged beside him.
Not far away, Little Yellow stood guard cautiously, as if acting as his Protector.
The morning sunlight spilled over Liu Yi as he prepared to charge into the Foundation Establishment Realm.
Despite being well-prepared, he still felt a bit nervous.
After all, Foundation Establishment concerns one's life; there is no room for the slightest error.
He took a deep breath, calmed his mind, and slowly closed his eyes, beginning to circulate the Foundation Establishment Cultivation Technique he had obtained from the Tianqi Sect.
He didn't plan to modify this set of techniques because changing them at will was too dangerous; once Foundation Establishment fails, all efforts would go down the drain.
At this moment, he only sought a smooth Breakthrough. Once Foundation Establishment was complete, he would create his own Cultivation Technique according to the cultivation System he had conceived.
In an instant, the Aura around Liu Yi's body erupted! Five brilliant divine lights coiled like flood dragons, enveloping his entire being.
The Heaven and Earth Spiritual Qi was drawn in as if by an invisible force, turning into a surging torrent that frantically poured into his body.
However, the thin Spiritual Qi of the outside world could hardly satisfy the requirements for the Breakthrough. His body was like a parched desert, crazily devouring energy.
Liu Yi waved his palms rapidly, and 20 Mid-Grade Spirit Stones instantly suspended in mid-air.
The majestic Spiritual Qi contained within the Spirit Stones was quickly extracted and poured entirely into his Dantian.
In the blink of an eye, the 20 Mid-Grade Spirit Stones were completely consumed by him.
Immediately after, he picked up the energy storage devices and absorbed the energy inside all at once.
When the energy from the last energy storage device was exhausted.
With a faint, ethereal chime, the Five-Colored Divine Light suddenly expanded by ten feet, then quickly retracted like a receding tide.
Liu Yi slowly opened his eyes, a spiritual charm unique to the Foundation Establishment Realm flowing within his pupils.
At this point, he had finally successfully broken through to the Foundation Establishment Realm!
He reached out and carefully felt his body, sensing that it was once again filled with vitality.
In the past, although he looked young on the outside, his internal body had long since become aged and decrepit.
It was completely different now; the power of the Foundation Establishment Realm flowed through his Meridians, and his body was brimming with life force.
"Hahaha, I've finally gained a new life! I've borrowed another 150 years from the heavens." Unable to hide his excitement, he laughed aloud.
"I no longer have to live in fear every day, dreading the day my Lifespan runs out. These years have truly been too difficult!"
"Finally, I can go and realize my ideas!"
"Just you wait, I'll let you witness the shock from another world."
Seeing his master wake up, Little Yellow barked excitedly without stopping, his tail wagging like a rattle-drum.
He jumped and skipped around Liu Yi, occasionally rubbing his head gently against his pant legs, his affectionate manner showing pure joy.
"Alright, Little Yellow, you go to the side for a bit. I need to stabilize my cultivation."
Liu Yi patted Little Yellow's head, then closed his eyes and began to circulate his technique to stabilize his Realm.
Carefully examining the condition inside his body, he couldn't help but sigh in his heart.
"Sigh, although I've successfully broken through to the Foundation Establishment Realm, my strength hasn't increased much."
"This Foundation Establishment technique from the Tianqi Sect simply cannot unleash the potential of 129,600 acupoints. It seems that creating my own cultivation System and technique is an urgent matter that cannot be delayed."
However, this successful Foundation Establishment not only brought his Realm to the next level.
But his control over the space-time realm also jumped to 10%, and his own deduction and calculation power increased significantly as a result.
If his previous deduction power was compared to a bicycle, it was now like he had switched to an electric scooter.
With such an improvement, he felt more confident about creating his own cultivation System in the future.
Moreover, if he combined it with the latest cheat brain, his deduction power could increase by more than ten times.
Although this thing consumes a lot of energy, Liu Yi has already made energy storage devices, so this bit of energy consumption is nothing to him.
However, the current energy storage devices and cheat brain are made of ordinary Refined Iron.
If he could get his hands on better Materials, these two items would surely see an even greater improvement.
Most importantly, he had a new idea for the energy storage device and the cheat brain.
He planned to integrate these two items with the System, which would satisfy the System's energy needs for operation.
And it would allow the System to function as both an energy storage device and a cheat brain, while also using energy as System currency.
In this way, the problem of System currency would be solved, and the Host could also use the System's energy to Cultivate.
What's even better is that the System could also absorb energy from heaven and earth on its own and store it to ensure its own operation, with the excess energy becoming Liu Yi's reserve energy bank.
Whether it was for cultivation or for replenishing energy during deductions, it would be extremely convenient, with countless benefits.
Furthermore, doing this wouldn't harm the System Host, and Liu Yi would gain an energy storage device and a cheat brain for free.
However, the road to realizing these concepts is full of thorns and definitely cannot be completed overnight.
If he could weave the System with the power of Laws, those exquisite functions would naturally fall into place.
But with Liu Yi's current strength, wanting to control Laws is nothing short of a pipe dream.
Out of necessity, he also thought about using Mental Energy to replace Laws in constructing the System.
But in that case, the System's functions would inevitably be greatly diminished, and in the end, he might only be able to make a Budget Version of the System.
Thinking of this, Liu Yi couldn't help but let out a long sigh. "A journey of a thousand miles begins with a single step. You have to take it one bite at a time. There's no use in rushing; I'll just have to endure it slowly! I'll create the cultivation System first."
"The priority now is to mass-produce the energy storage devices and cheat brains as soon as possible."
Liu Yi's eyes were bright, his fingertips unconsciously stroking his chin. "An increase in calculation power can speed up the deduction process, and sufficient energy is the Foundation of cultivation. Both of these preparations are indispensable."
"But there's no need to refine too many; after all, it's too time-consuming."
"There's still a lot of room for improvement in these energy storage devices and cheat brains, and the speed of subsequent updates will be very fast. There's no need to spend too much effort on the current version."
