The Penetrative Fist was a skill that allowed Lex to control a large sum of energy and release it while striking an opponent.
However the energy instead of being used to fuel the impact, it would be controlled by Lex and carried into the opponent's internal body that was weaker than the external body to damage the opponent.
Depending on the amount of energy and the strength of the opponent, the skill could instantly kill an opponent after destroying key internal organs and the energy would explode within the body of the opponent.
The sudden surge of energy that couldn't be digested by the opponent, as it was Lex's energy, would attempt to escape from within the opponents body and when it couldn't, it would explode after reacting with the opponents energy.
While Lex was using his Dominant Eye and realising that it was similar to the Telekinetic Eye, in the way that it allowed him to control an invisible force with his eyes, Lex had the idea of using his own energy as an invisible force that he could control.
But after pondering on it, he couldn't figure out a way to do so until he was using the Elemental Ascension Method and matched it with other skills, experiences and ideas that he had.
The Elemental Ascension Method focused on forming a connection and link with Lex's body and the elements, without using force or attempting to control them, while instead wielding and manipulating them to his will.
With that idea and the problem, that he faced even in his past reality when facing opponents with hard exteriors, Lex formed the Penetrative Fist that was a skill that allowed him to penetrate through his opponents exterior and damage them internally.
It imbued the Attack Jolt Skill into his fist and controlled the energy, so that it would penetrate into the body before inflicting its damage.
However, without much time to practice and perfect the skill, Lex only had a prototype of the skill that he was still developing and yet to test out on a real-life opponent.
The 10 seconds he took to activate the skill, that he had never used before, was enough time for the wild and infuriated Rock Worm King to break free of its restraints.
But it was too late and Lex had managed to activate the skill.
Within his right arm and fist, Lex stored incredible amounts of energy as he activated his Spacial Eye.
Spacial Eye
Body Jolt
As Lex's eyes were engulfed in a void-like emptiness, he suddenly jolted his body forwards, directly above the Rock Worm King's head.
"Penetrative Fist" he roared as he struck down with his right fist that was bursting with energy.
The fist seemed to be an ordinary fist and the energy didn't have an impact on the Rock Worm King's body, but Lex controlled the energy to penetrate through his body.
In order to do so, Lex used the Attack Jolt Skill and the way he seeped his body underground and managed to control his energy past the exterior of the beast.
"Now die" bellowed Lex as he relinquished his control over the energy he had placed within the head of the Rock Worm King.
The sudden burst of energy with the Rock Worm King caused an explosion within his head, and its hard exterior worked against it and didn't allow the energy to escape, increasing the damage the attack caused.
With its brain blown to pieces, even with its incredible strength, the Rock Worm King had no way to survive and collapsed to the ground.
The collapsing of the Rock Worm King's enormas body shook the ground as Lex sat on its body and let out a sigh of relief as his gamble to use a skill that he had neer practiced paid off.
{Ding, the host has created his own skill, Penetrative Fist, that uses both the host's Eye Powers and mental control. For this the host has been rewarded a B Rank Eye Power} announced the system.
Lex had a satisfied expression as the idea he had for a skill succeeded and he had manged to defeat the Rock Worm King without suffering any injuries.
[Use the B Rank Eye Power Draw] ordered Lex, wanting to see what Eye Power he would gain.
{Ding, the Host has gained the Energy Projectile Eye. This is an Eye Power that allows the host to compress large amounts of energy into his eyes, which is controllable, and shoot them as projectiles aimed at oppents} announced the system.
[Why is it B Rank and what can it do] asked Lex, wanting to get a detailed overview of the Eye Power he gained.
{Ding, the Eye Power is B Rank because of its basic and simple use and because it only had one application. However, this application can be used in multiple different ways, such as imbuing different elemental properties to the Energy Projectiles, and the host will have to build upon the ability to bring out its true potential} answered the system.
"Interesting. I will experiment with it later on" mumbled Lex to himself.
Retracting his Armadillo Armour, Lex began to repeatedly strike the skull of the Rock Worm King, wanting to acquire its beast core.
The watching rock worm beasts were all shocked by the death of their king and were all afraid to battle against Lex as they all attempted to escape.
After a few minutes and striking the Rock Worm King's head hundreds of times, Lex finally managed to break through its exterior and the beast's splattered brain was revealed.
Sticking his arm inside, Lex withdrew the dark brown beast core that was full of energy and placed it within his inventory.
[I will need the beast cores of all the beast kings in the Underground Coves and many Heaven Mortals in order to break through] estimated Lex, knowing how hard it would be to break past the bottleneck that he had reached.
"Time to collect some more beast cores" stated Lex to himself with an amused smile as he saw the large and powerful rock worms scrambling to escape from him.
