The main reason Yu Tianheng chose the " Nine Heavens Thunder Prison Suppression Scripture" was to deceive others.
It should be noted that cultivation techniques do not exist in the Douluo Continent at all; in other words, no one has ever come into contact with them.
They had absolutely no idea what a cultivation technique was.
People only cultivate their Martial Soul, improving their cultivation through meditation.
While martial arts techniques can demonstrate a variety of abilities, if they differ from the attributes of one's Martial Soul, they can easily arouse suspicion.
For example, if someone's Martial Soul is Fire Dragon and they learn an ice-attribute technique, they might accidentally unleash an ice attack during a battle.
It's hard not to arouse suspicion.
They might wonder, a Soul Master with Fire Dragon Martial Soul should theoretically primarily use fire in their attacks, so why would they use ice, an attack with the opposite attribute?
Why is that?!
Once suspicion arises, the consequences are unpredictable.
If it's just suspicion, that's one thing, but if it attracts the attention of the Spirit Hall and they discover something, and then arrest and torture him, then the trouble will be much bigger.
Therefore, before one's wings are fully grown, one can only cultivate in secret.
The " Nine Heavens Divine Lightning Prison Suppression Scripture " is undoubtedly a thunder-type technique. After cultivating it, one will have the ability to control Thunder, which is compatible with the ability of the Blue Lightning Tyrant Dragon Martial Soul to control thunder. Even if it is discovered that the power of his thunder is incomparable to that of ordinary Soul Master, most people will think that Yu Tianheng is a person with extraordinary talent, and will not think that it is because he has cultivated a powerful technique.
Furthermore, choosing this technique has an even greater advantage: it can be passed on to the members of the Blue Lightning Tyrant Dragon Clan, especially his grandfather Yu Yuanzhen, whose current Soul Power Level is 95.
He looks quite powerful, but there are quite a few Titled Douluo of similar level across the continent.
Especially in the Spirit Hall, there are at least ten Titled Douluo who have reached this level, and possibly more.
Therefore, if a war were to break out with the Spirit Hall, Yu Yuanzhen would most likely be surrounded and killed, and in the original storyline, that is exactly what happened.
The best way to change this situation is to improve Yu Yuanzhen's strength and allow his Soul Power Level to break through, ideally reaching level 99 and becoming Limit Douluo. Only then can he stand at the pinnacle of the entire Douluo Continent.
And as the grandson, he could now roam freely in the Douluo Continent, with no one daring to provoke him.
However, after reaching the Titled Douluo level, each advancement becomes extremely difficult, especially after reaching level 95. Each breakthrough requires at least ten or even several decades of Soul Power accumulation, and even with sufficient Soul Power, breaking through is not easy.
Although Yu Yuanzhen had good talent, reaching level 95 in his lifetime was almost the limit.
However, because Yu Tianheng taught him the " Innate Skill ", his Soul Power Level might be able to advance further and break through level 96.
But that's about it; it's difficult to improve further.
However, if Yu Tianheng were to pass on the " Nine Heavens Divine Lightning Prison Suppression Scripture," which is at the Heaven level, to Yu Yuanzhen and have him cultivate diligently, he might be able to achieve even greater success with the powerful force of the technique.
But before that, Yu Tianheng planned to cultivate on his own first to see how effective it was.
If the effect is good, then pass it on to Grandpa Yu Yuanzhen so that he can cultivate it and increase his strength.
With this thought in mind, Yu Tianheng sat cross-legged and began to examine the cultivation steps of the " Nine Heavens Divine Lightning Prison Suppression Scripture ".
After reviewing the cultivation technique, Yu Tianheng understood.
There are four stages in practicing this method.
The first stage Drawing Lightning into the Body.
Choose a time of thunder and lightning to go to a high mountain peak or an open area to look for strong sources of lightning, such as ancient trees struck by lightning or towering peaks. Lightning power is concentrated in these places, making them more likely to be triggered.
Afterwards, he calmed his mind, sat cross-legged on the ground, abandoned distracting thoughts, cleared his mind, and used his powerful mental strength to establish a connection between himself and the lightning, guiding the power of the lightning into his body with his intention.
The second stage is Thunder Body Tempering.
The lightning power drawn into the body circulates along the eight extraordinary meridians and twelve regular meridians, washing away impurities and blockages in the meridians, strengthening their resilience and endurance, and allowing the body to gradually adapt to the power of lightning.
Afterwards, the internal organs are strengthened by introducing the power of lightning into them, tempering the five internal organs and six bowels, enhancing their functions, and enabling them to withstand more powerful lightning energy, thus laying the foundation for subsequent cultivation.
The third stage is the Condensing Lightning into a Pill.
First, gather the power of lightning. Once the body can skillfully guide and withstand the power of lightning, gather the lightning power scattered throughout the body into the dantian, forming a vortex of lightning energy with the dantian as the center.
Afterwards, the elixir takes shape. Using special cultivation methods and focused intention, the gathered lightning power is compressed and condensed, gradually forming a Lightning Pill. The formation of the Lightning Pill signifies that the cultivator has reached a new level of control over lightning power.
The fourth stage: Controlling Lightning to Suppress the Prison.
By comprehending the essence of thunder, one can deeply understand the laws and power of lightning contained within the Lightning Pill, comprehend the fierceness, speed, and destructive nature of thunder, and integrate these essences into one's own combat skills and spells to make attacks more powerful.
It can unleash wide-range attacks, such as summoning powerful divine thunder to form a thunder prison that traps enemies within, using the power of the divine thunder to destroy their bodies and souls, thus achieving the purpose of suppression and killing.
After reading it, Yu Tianheng was slightly shaken, thinking to himself, "As expected of a top-level Heaven-rank cultivation technique, it is indeed quite ingenious. Even the most basic technique, 'Drawing Lightning into the Body,' requires immense courage to master."
Even though Yu Tianheng's Blue Lightning Tyrant Dragon Martial Soul possesses the ability to control lightning, and his physical body is powerful after cultivating Martial Dao, he still doesn't dare to attempt to cultivate the introductory stage of " Nine Heavens Divine Lightning Prison Suppression Scripture," namely " Drawing Lightning into the Body," right now.
"After all, this is basically like getting struck by lightning; one wrong move and you could die."
Therefore, Yu Tianheng decided to postpone cultivating this Heaven-level technique and first cultivate the body-tempering technique " Golden Body Art ".
After cultivating one's physical body to a sufficiently strong level, one can then Drawing Lightning into the Body.
Yu Tianheng sat cross-legged in the quiet room, his eyes closed, his expression solemn and focused. As the mental cultivation method of the " Golden Body Art " slowly flowed through his mind, he took a deep breath, slowly closed his eyes, and let his consciousness sink into his body, beginning to guide the surging Bloodline Power.
In an instant, the blood and qi in my body surged and churned through my meridians like a ferocious beast awakened.
Yu Tianheng carefully guided this force, directing it first towards the leg bones.
At first, the Bloodline Power flowed between the bones of the legs, bringing a slight tingling sensation, as if countless fine needles were gently pricking.
As the guidance deepened, his leg bones felt as if they were being placed in a blazing furnace, and a searing pain spread throughout them. Yu Tianheng clenched his teeth, large beads of sweat rolling down his forehead and wetting the ground in front of him, but he did not waver in the slightest.
