Lex trained his body for half of a day, then absorbed the 2 clones that were cultivating and training, leaving the clone that was learning the Mental Void Method.
After absorbing and strengthening himself he reformed the two clones again and gave them the same instructions, but this time Lex cultivated his energy and after another half of a day reabsorbed the same two clones.
After suppressing and absorbing the energy and power from the clones, Lex had strengthened himself once again and could feel that he was nearing a limit that he would need to surpass.
After another half of a day, Lex completed the same cycle, however, this time felt as though he had reached his bottleneck of some sort and was unsure of what to do.
Conveniently the clone that was learning the Mental Void Method finished while he was contemplating on what to do to break past the bottleneck that he had reached.
He placed his palm on the clone and as soon as he retracted the cloning he instantly felt something jolt into his mind as everything that the clone had obtained in knowledge of the Mental Void Method was transferred into his mind.
Angela and the Jade Empress within the golden hall could hear inhumane screams of pain from within the room that Lex was in as his mind was pulsating with excruciating pain.
Suddenly jumping up, Angela was about to run over to Lex with a worried expression.
"Focus on your cultivation child and don't worry about your friend, he is strong-willed and seems to be pushing himself past his limits to gain strength as quickly as possible" stated the Jade Empress to Angela who knew that if she intervened it could have bigger consequences and wanted her disciple to focus and take in everything she was taught before her Soul force diminished.
Angela sat back down, but still found it hard to concentrate with the constant screams.
After almost half an hour of constant screaming, they finally reached a halt after Lex managed to regain control himself enough to stop screaming.
It was an extreme pain that he went through as he squirmed around on the ground and screamed at the top of his lungs as his mind felt as though it was about to burst.
It was not until an hour passed that Lex was actually able to function and sat up and streamed large amounts of energy to his head and circulated it to attempt to reduce the pain and recover from the mental strain.
"How the fuck is this only slightly painful" mumbled Lex with his now hoarse voice after all the screaming, remembering the system had described it as only slight pain.
It took Lex an entire day to almost completely recover where the continuously pulsating pain reached a level that wouldn't have an effect on Lex's functionality and he was too eager to begin cultivating with his new cultivation method to care about the pain.
During the day that he was recovering from his mental strain, Lex also scoured the beginning parts of the method that showed him how to cultivate the Spacial Element by using the eyes, mind and emotions and linking them to the void, and found exactly what he was looking for.
There was a method for him to break through to the Earth Mortal Rank that would usually take a few months or years for people to overcome the barrier, but for Lex, if he followed the method, he would be able to accomplish it within a day.
He didn't need to worry about food to sustain his body and neither did Angela with the dense and thick energy in the environment within the temple that the Jade Empress accomplished with the abundant amount of Corpse Cores she had accumulated over the time she had been there.
The method instructed him to reach an ethereal state where his emotions and mind would reach a harmony where he would become unaffected by anything and would become empty in the same way the void is.
The gap between the Mortal and Earth Mortal rank for a human is when they ascend past their mortal origin and officially become cultivators and begin as Earth Mortals which is the starting LVL of cultivation and because of humans being born as a weak race, they have to train to reach that stage.
Humans despite being one of the weakest races from birth, they are also known for evolving and consistently improving and mutating to produce more and more talents over time and have the largest population.
The Mortal Rank was merely a pathway for one to prepare their body for true cultivation and requires at least ten times the strength of a normal Mortal to begin.
Which is why out of the 100 LVLs each one would normally increase the user's strength by 10% making them 10 times stronger by the time they reach the Mortal Rank, whereas, in Lex's situation, his strength was already comparable to that of a low LVL Earth Mortal that had stepped into the realms of cultivation.
[I need to break past the limits of suppressed mortality and need to break into the ranks of real cultivation. So according to the Mental Void Method, I need to break past the chains of being suppressed both in terms of Internal and External Cultivation and will use large amounts of Spacial Energy to push my body past the limit in one burst of power] he thought to himself.
"But there is one problem, it will only work if my mind and emotions are as clear, endless and empty as the void and if my mind can't reach a void-like state, I will suffer extreme backlash" he mumbled to himself with a worried expression.
Then it struck him.
"I have the perfect solution. My clones don't have emotion and have a clear and empty mind anyway so they can initiate the breakthrough state for me and I will absorb their gains all at once which will allow my body to break into the Earth Mortal Rank in the Spacial Energy Burst that is in the Mental Void Method" he exclaimed.
The plan was perfect, the only contingency was whether Lex would be able to stay in the void-like state during the absorption process.
Forming 3 clones one after the other, stopping between each one to recover his energy, Lex had three clones sat before him on the gravitational pad that was multiplying the gravity over them.
"Use the Mental Void Method to cultivate spacial energy and cultivate both your Internal and External Cultivation and absorb as much energy as you can" ordered Lex to his clones
The Mental Void Method was a wondrous cultivation ability and its main focus was the mind as the name suggests. It wasn't to improve or strengthen the mind, but was to allow the mind to stay clear and unaffected by emotions and anything else, in the same way that the void is.
For this Spacial Energy Burst to be successful, it was all down to Lex's mental state when he uses the energy from the clones to break his body past the barrier of the Mortal Rank that would usually take a lot of time in order for him to be able to do so.
Sitting in between all three of his clones as they were all huddled close together and sitting cross-legged, Lex made sure that he was in contact with them in preparation for the Spacial Energy Burst that needs to be large and sudden.
Lex following the method to calm his mind, closed his eyes and attempted to link his mind to the void in order to enable him to be able to gain the clarity that the emptiness of the void would provide him.
Emotion was shunned in the process and Lex focused on his mind being clear and unshakable just like the void and after what felt like an instant and an eternity Lex felt that same sensation that he was in the void.
However, instead of struggling and thinking to himself that he is suffocating in the void, like he did when he accidentally activated the method, Lex knew that it was part of the method and kept calm as he felt his body float through the void.
The method explained to him that it was merely an astral form and extension of himself that would act as a link between himself in the void and allow him to cultivate pure Spacial Energy from its root and allow his mind to experience true emptiness.
After a few seconds, he felt that his astral form was tearing and couldn't sustain the pressure and after exactly 5 seconds shattered as Lex suddenly opened his eyes and found himself still in the training chamber with his clones.
"I was able to last 5 seconds this time and not be instantly wiped out" he observed as he wiped the sweat off his forehead.
What felt like 5 seconds within the void was actually 5 hours in reality and the time in the void could flow much faster or could also flow much slower.
Feeling the brimming energy from his clones that were much more suited to cultivating the Mental Void Method, Lex felt that he had cleared his mind and could feel the emptiness that the method described.
It was neither a good nor a bad feeling, but Lex felt as though his mental state was stronger than it had ever been and knew that the effects of the Mental Void were only temporary, but would rub off on the user over time, so knew it was the optimum time to attempt the breakthrough.
Reabsorbing all his clones at once and keeping calm as he was swarmed with a large amount of Spacial Energy cultivated by his clones, Lex spread it to every cell in his body and around all his meridians and his dantian as he forcefully stored it as the Spacial Energy Burst had described.
It was over in a matter of instants as there was a large explosion.
