Originally, Leto would have had to expend considerable effort to extract the codex from little Clark's body, but with Jor-El's help, the process became much simpler!
When he injected the codex into his son's body, he had already considered that one day it might need to be removed.
However, in his imagination, his son would be the one to make that choice, but reality dealt him a harsh blow, with Zod reaching this point first.
To avoid harming his son, Jor-El controlled this process with the utmost precision.
After three full days of busy work, the complete codex was finally extracted in its entirety.
And for the upcoming Krypton reconstruction plan, they also needed to find a new physical vessel for the codex.
Ultimately, the new vessel they chose was the skull of a Kryptonian compatriot, who had died many years ago, found in the Kents' spaceship.
During these three days, Zod flew directly to the closest point to the sun, operating the True Sun Scripture, frantically absorbing the energy emitted by the sun without a moment's pause.
If the Kryptonians' instinct to absorb solar radiation is likened to a normal charging mode, then with the blessing of the True Sun Scripture, it transformed into rapid fast charging.
Visible streams of solar radiance were devoured by his body.
Moreover, thanks to the unique physiological functions of Kryptonians, they can quickly convert absorbed solar radiation into the vital essence they need.
Even more terrifying is that as long as the sun exists, his body is like a precise machine that never stops and operates efficiently at all times.
In fact, as his strength increases, the operating efficiency of this machine will become faster and faster.
Therefore, even without other cultivation resources, Zod's cultivation speed was terrifying, with almost infinite vital essence turning into true fire, burning away impurities in his sea of suffering, and simultaneously expanding his sea of suffering.
At the same time, the vital essence, refined by the True Sun Scripture, continuously nourished his physical body.
He could clearly feel that the improvements made over several months in space were not as rapid as those achieved in these short three days.
In three days, the sea of suffering within him had expanded to over three zhang, emitting a radiance like the sun.
Not only that, but he had already condensed a full forty-nine divine patterns according to the methods in the True Sun Scripture.
According to the normal cultivation process, he should be considering what 'tool' he should forge to be his future Dao-proving artifact.
However, since he had no other cultivation methods besides the True Sun Scripture for reference, nor any guidance, all the cultivation insights he inherited were only about this imperial method.
Therefore, he had no other choice; the 'tool' he forged, like the Sun Saint Emperor who created this imperial method, took the form of a pagoda as its vessel.
Fortunately, with the most detailed cultivation inheritance, he did not need to slowly explore; everything flowed as smoothly as water.
He could feel that he had not yet reached the point where he could advance to the Life Spring.
Next, what he had to do was to continue cultivating step by step, continuing to ignite the true fire to burn his sea of suffering until it was completely transformed into a 'Sun Sea of Suffering'.
Then came the concise of divine patterns and the forging of his own 'tool'.
Stopping his cultivation, he flew back to the base in the Arctic.
Leto and Jor-El, after extracting the codex, did not stop either, beginning to construct a more stable protective force field to avoid unnecessary trouble.
The commotion Zod had caused earlier had already alerted many forces on Earth.
If they were not preparing for war with humanity, then concealing their traces as much as possible was better for both sides.
"Zod, what have you done these past three days? Why do I feel like you've changed again!"
When Zod reappeared before Jor-El, he asked with a tone of surprise and doubt.
Achieving a small degree of success in cultivation brings a very obvious change in one's temperament.
If the previous Zod still had some of the iron-blooded temperament of a former Kryptonian military commander, that temperament had now almost completely disappeared, replaced by a truly leadership-like aura.
"Of course, I'm developing our racial talent. If you still had a physical body, perhaps you could experience this feeling."
One sentence instantly silenced Jor-El, because he was personally stabbed to death by Zod.
"Alright, just a joke, don't mind it."
"Bring Clark here. I promised his adoptive parents that I would send him back after extracting the codex from his body. Three days have passed, and I'm afraid they've been waiting anxiously!"
Seeing that Zod no longer had his former sternness, and could even joke like an ordinary person, it was a novel experience.
Especially since he could still honor a promise with an ordinary Earth couple, Jor-El felt that this Zod was more admirable than the iron-blooded general he once was.
"Thank you!"
Jor-El looked at Zod and said seriously.
Zod casually waved his hand, then carried little Clark and flew directly to his adoptive parents' home.
At Kent Farm, Jonathan and Martha had been in a daze ever since Clark was taken away, doing everything distractedly.
During this time, the most frequent thing they did was stand in the yard, gazing at the sky, hoping to see that figure appear again.
Three days felt harder to endure than three years in their hearts.
"Jonathan, Clark will be alright, won't he!"
Martha had asked him the same question countless times over these three days.
To this, he could only hug her and comfort her: "Don't worry, Clark will be fine."
In truth, he himself was incredibly anxious about the matter, but as a man, he couldn't show a disheartened side in front of his wife.
And just as the two were leaning against each other, comforting each other, a figure silently landed before them.
Upon seeing Zod and Clark in his arms, the couple rubbed their eyes in disbelief, confirming they weren't hallucinating.
"Mr. Jonathan, your child, I have safely returned him."
Saying this, Zod handed Clark to Martha, who was visibly emotional but forcefully restrained herself.
"Thank you, Mr. Zod, thank you so much!"
Jonathan kept thanking him, his eyes never leaving Clark.
"Mr. Jonathan, I think you already understand that Clark is destined to be different from ordinary people. He possesses the potential to inspire hope in everyone."
"As a father, you might be able to guide him well. In the future, if he feels lost, you can have him come to the Arctic; there he can find the answers he seeks. Remember, let him get plenty of sun exposure; it will greatly help his growth."
Zod did not want to change Superman's life trajectory too much; he still hoped that Clark would wear that uniform in the future.
Although he had lost the codex within him, the impact on Superman was almost negligible.
Jonathan also said with a serious expression, "Don't worry, I will guide Clark well."
"Oh, a friendly reminder: if one day in the future, your family encounters a storm, please don't be reckless. It's better to let Clark handle some things."
Before leaving, Zod seemed to recall something and added a remark to Jonathan before flying away.
In his previous life, Zod greatly admired the character of Jonathan Kent. If he truly returned to that destined trajectory in the future, he hoped his reminder could save his life.
Martha asked with some confusion, "Jonathan, what did Mr. Zod mean by his last words?"
"I don't know, perhaps it's some kind of prophecy. After all, he's like a god from legends."
Regarding his wife's confusion, Jonathan himself was also puzzled, but he felt that the other party wouldn't speak idly and that there must be some deeper meaning. He firmly kept these words in his heart.
