Arjun has couple of evidences to back his theory. Back when he entered his Mind Palace for the first time, he asked for some advice from the Void. But for some reasons, he couldn't get any response from the Void. Today he was sure that, the reason why he couldn't get any response from the Void is because his Mental Energy was blocking the presence of void.

And the second reason is his stats notification. In his stats notification everything was detailedly put neatly. He could find every bit of information regarding his cultivation on the stats notifications. But he didn't find any related information regarding his Mental Energy, Mental State or Mental Strength!

Back then he didn't give it much thought. But today he has to think about it very carefully. Even his Void Qi was blocked from entering his Mind Palace by some kind of mysterious energy.

Unknowns are definitely scary. If he doesn't have any assistance regarding Mental Energy, then he would be in an helpless state. And he wouldn't neglect Mental Energy just because he could establish communication with his Void Qi. He wouldn't compromise on anything.

If he was someone who would have gone for compromise, then he wouldn't have became an Universe Will back then. This was his persistence. And he wouldn't have neglected his Mental Energy even if it has low value. Needless to say now where he found that his Mental Energy could block his Void Qi from entering his Mind Palace!

What is Void Qi's origin? It is from the Primordial Energy! And yet, his Mental Energy could block his Void Qi from entering into his own Mind Palace! How could Arjun neglect if something could block even his Void Qi so casually?

Even though he wouldn't get any assistance, Even though he was on his own now, He wouldn't back down from uncovering the mysteries regarding Mental Energy, Luminous Energy and that Doorway to his Mind Palace!

Arjun calmed down and entered the outskirts of his Mind Palace again. After entering, he looked at the door. And his eyes fell on the Luminous Energy swirling non stop around the palace entrance door.

Arjun already had a little idea of how to deal with this situation. He had to gather the Luminous Energy and slam it on the doorway to the entrance of his Mind Palace. Even though it didn't open the door, but the fact that the door shook a little didn't escape his eyes.

Arjun remembered that back then, he did manage to gather the Luminous Energy. But it was just a little. And this little bit of Luminous Energy drained all his concentration. His mind was put on a fatigue sensation. Ge felt as if his mind was burdened with some kind of invisible heavy weight.

Even though, his concentration was drained, he wouldn't have given up. If it wasn't for his family which was in a grave danger back then, he wouldn't have given it up. Back then giving up was temporary retreat. But since he had nothing but time, he won't give up this time.

He started to concentrate on the Luminous Energy once again. The swirling Luminous Energy started to gather around Arjun as if his concentration was the key for it's summoning.

But even after spending great deal of concentration, all he could gather was still handful of Luminous Energy.

Arjun was angry. He always rated himself highly. And yet his concentration level was amount to only handful amount of Luminous Energy?

Ridiculous!

Arjun Extracted all is concentration level to it's limits. Some more luminous energy gathered around him. But Arjun was not satisfied. By now he was sure that, if he could gather all the luminous energy in the surrounding and smashed on the door, only then the door will open for him. All is concentration level has been drained and yet all the he could muster up is only the handful amount of luminous energy.

Arjun gritted his teeth. He activated his Unique Dao of Concentration at it's full limit and tried again. This time the result was little bit under his favour. After activating the Unique Dao of Concentration, the Luminous energy that gathered around Arjun was immense. Around half of the swirling Luminous Energy moved and gathered around Arjun.

But even this result didn't satisfy him. Even after activating the Unique Dao of Concentration, all he could gather is still half of the swirling Luminous Energy? Then what should he do in order to control every bit of the Luminous Energy?

He gritted his teeth in rage. He immediately activated his Unique Dao of Understanding, Unique Dao of Comprehension, Unique Dao of Immersion and Unique Dao of Wisdom at it's limits.

This time even with the Activation of four more Unique Dao, all he could gather was around eighty percent of the Luminous Energy. He still had to find a way to gather the rest of the Luminous Energy.

Arjun sighed. He knew that he is close. He is close to gather every bit of Luminous Energy! But he used up all his aces up. He had no other trump cards in his arsenal to boost the gathering of Luminous Energy.

\"To hell with it!\"

Arjun shouted in anger. He took a deep breath and tried his best to concentrate on the rest of the luminous energy with all his efforts. No! This time he decided to go all out and break his own limits!

As a concentrated on the luminous energy, he felt as if the weight on his brain was increasing. His fatigue sensation was increasing.

\"Not enough!\"

Arjun told himself. He felt as if his head is going to explode when he concentrated more than his brain could endure.

\"AAARGH!!!\"

Arjun shouted as he spent even more concentration level. But increasing the concentration level has enhanced the burden on his brain. This time the burden was equal to when a giant mountain was placed on his head. But somehow he managed to gather a total of eighty five percent of Luminous Energy!

He didn't give up. He put even more efforts. This time the effort was much higher than the last time. He felt as if his brain is about to explode into pieces. His eyes, nose, mouth and ears started to bleed! His eyes were about to be darkened as he couldn't see anything properly. His body was sweating vigorously.

But he still managed to smile. Even under such a huge amount of burden, he managed to smile. Because he knew that despite this huge burden, his hard work paid off.

Because he successfully gathered all the Luminous Energy!
