Su Xing was stunned at the sight.
These were not a thousand Grandmaster-level experts, but a thousand Heavenly King-level experts!
The Dragon Spirit Pills and Origin Martial Pills that Su Xing painstakingly developed before had only increased the number of Heavenly King-level experts in the Great Xia Country by a few hundred.
But he hadn't expected the effect of the Rebirth Pill to be so incredible!
The Rebirth Pill was purely aimed at power-type martial artists, helping them enhance their strength.
Although there would be a side effect of decreased rationality for a few months, it would be restored within a year at most.
This efficiency in improving strength could only be described as astonishing!
If Su Xing was willing to continuously refine the Rebirth Pill, it wouldn't be an issue to increase the number of Heavenly King-level experts by a thousand each year.
"Moreover, this is made using the flesh essence of a Demon King..."
"If it's made using the flesh essence of a Demon Emperor... the strength increased would be on the level of Heavenly King experts by then!"
"At that time... with the increase in the strength of Heavenly King experts, there would be a greater likelihood of them advancing to become Martial Emperors!"
A gleam flashed in Su Xing's eyes, and he murmured:
"With more Martial Emperors... could there still be few Legendary-level ones?"
"If there were truly dozens or even hundreds of Legendary experts... then twenty years later, when those hundreds of Legendary Demon Clan attack the city, could they be stopped?"
Su Xing felt a bit of joy in his heart.
If that were the case, even if it couldn't be stopped, it could at least buy a few more years.
This would mean that with each simulation, Su Xing would gain several more years...
By that time, Su Xing would have more time to cultivate and explore the secrets of this world.
Thinking of this, Su Xing's heart was a bit excited.
"The twenty-five-year limit... maybe it could be broken soon!"
Su Xing was a bit eager to give it a try.
After calming his emotions, Su Xing began to plan the objectives for the next simulation.
Currently, Su Xing's Protective Gang Qi and Origin Force cultivation had both reached the Great Perfection level.
It could be said that for withstanding consecutive lightning powers and stepping into the Broken Void Realm, Su Xing had a seventy to eighty percent chance of success.
The next step for Su Xing was simply to survive until the day the giant beast arrived and be swallowed into its belly to complete the mission.
"Survival in the next simulation is the primary task. Taking risks with one's life is absolutely not an option..."
"Of course, the remaining ten-odd years cannot be wasted. More exploration can be made into the things that need to be done next."
After some consideration, Su Xing decided to attempt two things in the remaining time.
First, continue to develop the Rebirth Pill using flesh essence from Demon Emperors.
Although Su Xing couldn't take out the elixir refining experience, he could see to what extent the Rebirth Pill could improve the strength of the human race.
Second, he planned to cultivate the divine skill of escape technique—Sword Control Technique!
After all, after breaking through the void, Su Xing's Qi Refining cultivation should also keep up, reaching the Return to Void Realm.
And for this, Su Xing needed to collect Spring Dew Pure Water.
Thus, a qualified escape technique divine skill was essential...
With a plan in mind, Su Xing's gaze fell upon the simulation panel.
[Year nine, you dedicated most of your energy daily to refining and improving the Rebirth Pill.]
[This year, you tried adding flesh essence from a Demon Emperor. Unsurprisingly, due to the excessively violent medicinal properties and severe side effects, the pill formation failed.]
[But you didn't lose heart. You continued to refine the pill recipe, gaining more insights into the Rebirth Pill with each attempt.]
[In the same year, you began practicing the divine skill escape technique, Sword Control Technique.]
[Year ten, after a year of effort, the side effects of the Rebirth Pill had been greatly reduced but were still not suitable for use on humans.]
[Seizing the time, you continued to refine the improved Rebirth Pill, going through more than a dozen furnaces each day.]
[For this upgraded version of the Rebirth Pill, the main ingredient was flesh essence from Demon Emperors. When the essence wasn't enough, you went to the Demon-Subduing Pass to kill Demon Emperors and replenish the materials.]
[In a year's time, you killed nearly a hundred Demon Emperors and revised the Rebirth Pill over a hundred times.]
[In the focused life of alchemy, three years passed in the blink of an eye...]
[Year thirteen, this was the fifth year you had been developing the upgraded Rebirth Pill.]
[Over the five years, you revised and researched it thousands of times, finally obtaining an upgraded Rebirth Pill with the lowest side effects!]
[You spent three months to refine a thousand pieces of the upgraded Rebirth Pill and found three hundred Heavenly King experts and ten Martial Emperor experts to take them.]
[Even though you had improved it many times, the side effects of this version of the Rebirth Pill were still significant.]
[Because the flesh essence from the Demon Emperor was more violent, the Heavenly King experts who took this Rebirth Pill experienced varying degrees of emotional turmoil, and even manic depression.]
[Fortunately, you had prepared in advance, contacting psychologists, and had the three hundred Heavenly King experts admitted together.]
[It was truly a rare phenomenon to see three hundred Heavenly Kings all admitted for psychological treatment together.]
[Compared to the Heavenly Kings, the Martial Emperors experienced much milder side effects after taking the upgraded Rebirth Pill. They only occasionally experienced auditory and visual hallucinations...]
[Year fourteen, after a year of treatment, all the Heavenly Kings and Martial Emperors were successfully discharged.]
[After comparing your tests and statistics, you found that the strength of the professionals who took the elixir had grown rapidly.]
[Heavenly King experts, after taking the upgraded Rebirth Pill, had their strength increased by an average of forty percent!]
[Each Heavenly King expert, after taking three Rebirth Pills, saw their strength increase by two to three hundred thousand pounds with each pill!]
