The process to upgrade the Space-time Judgement Sword was slow from a general perspective, but in fact, it was far quicker than it should be upgrading a sword of that level.
If Yale was conscious, he would just upgrade it a bit and wouldn't dare to do great changes but while in his enlightenment state, he had no restriction.
The materials of the sword were unable to keep up with the upgrade process, so the sword should break at any moment, or at least that was what common sense said.
However, Yale managed to find a perfect balance to increase the resilience of the sword each time the materials reached the limit. It was a work that should be done in milliseconds despite being a lot of factors to take into consideration when doing it.
The only ways to accomplish something like that was being like Yale, in enlightenment state with the Celestial Knowledge activated or by being used enough to the process being done unconsciously.
Of course, that was speaking from the perspective of an Essence God because those stronger wouldn't have that much problem controlling the essences to improve a weapon to the Essence God level.
However, weapons at an Essence God level were already the strongest weapons crafted in the universe and at the same time, it was impossible to continue training blacksmithing past the Essence God level.
That was one of the main weaknesses of Yale's universe, and one of the main reasons for their war against the other universe in conflict with them was so difficult to settle.
The other universe was far older than their own, and although their knowledge couldn't compare to that of the ones in Tofesh's universe, it was still far better than in Yale's universe.
The other main problem was that there was only a standardized path until Origin God and surpassing that level was far too difficult, but the other universe had a path that reached that higher level, so although there weren't a lot of people at such level, they outnumbered the ones in Yale's universe.
The Origin Path was flawed. It was the main path designed by the universe creator to those who were born in his universe, but he didn't train it since he wasn't born there.
Of course, he knew that the path was flawed, but he was unable to design something better.
There hadn't been a shortage of experts who tried to fix those flaws, but the only one who managed to make a breakthrough differentiating himself from the Origin Path was the Battle God. However, he was struck at that level afterward unable to advance.
The information sent by Tofesh could fix the first flaw regarding weapons. As long as Yale practiced enough, he would be able to make weapons at a higher level.
However, the most important problem to solve was that of the Origin Path. The weapons were important because they would create a difference when both parties had similar power, but Yale's universe lacked people with the same power as the other universe.
Yale had been pondering about of following the Origin Path or not after learning about his grandfather and noticing that the Origin Path wasn't perfect, but he never thought of following his grandfather's path because it was also clearly flawed.
Although Yale wanted to create his own Path, he lacked the capability to do it. If creating a new Path was something easy, there wouldn't be only one person who had managed to do it.
However, while improving the sword, Yale's mind started to extrapolate ideas that seemed feasible to form a new Path. It was barely an outline, and it was difficult to say if it could be developed later on or not, but it was a great advancement.
Of course, Yale was still unconscious about that fact since he was still immersed in enlightenment while improving his sword, but he would remember everything after the enlightenment ended.
In fact, although Yale created just an outline of a new path and it was useless, it triggered a strange reaction of the Origin Path. The Origin Path inside Yale's soul had duplicated, and there were two identical Origin Paths inside his soul.
That was a reaction that could happen to those with an Origin Path, but the chances of happening were minimal. Besides asking someone at the level of the universe creator to create a new Origin Path, that was the only way to create one to give to someone else.
It was useless having two Origin Paths since there wasn't any increase in power just for that reason, but it was possible to use one to experiment creating a whole new Path without risking the one that was in use.
After all, if one messed with the Origin Path trying to improve it, there were a lot of chances of provoking a calamity and turning mad, so it was pretty good having the chance of investigating without risks.
The room where Yale, Lina, and the Dwarf King were working was huge since it was the hall of the royal palace, but the weapons created by the three of them were starting to fill the room.
Yale was focused on improving after having created a lot of weapons, but the other two were still creating weapons of improving old weapons, and since they were in enlightenment, they just toss to the floor any finished product, without regarding if it was a success or a failure.
Even the products considered a failure, they were still very valuable for common people, so it would have been a scandal if someone entered the royal palace, but since the guards were dead and the rest of people were scared by the ones who did it, no one had the guts to approach the palace.
Anyway, Yale had isolated it, so even if they tried to enter, they wouldn't be able to do it, so besides the three of them, only the Mysterious Expert noticed about what was happening there.
The Mysterious Expert was laughing while seeing the scene while being delighted by the unexpected events triggered by Tofesh.
"This is a miracle! I never hoped that there would be interference from a higher universe! Thank you, Tofesh! This is the best gift our universe could receive just now. Originally, the success rate of the plan was still quite low, but now it has increased a lot."
The Mysterious Expert was really happy at that moment, and he immediately sent the information to the universe creator through the Timeless Border. Since there had been an external interference on the universe, the universe creator noticed it and wanted to ask the Mysterious Expert about it.
The universe creator was also very pleased with the news since they were important for the survival of the universe, and since it involved the son of one of those at his level, and that same person was also a Timeless Sovereign, the importance that the universe creator attached to it was even higher.
After leaving the Timeless border, the universe creator also informed Yale's mother about it, and she was delighted by it while she killed some of the experts of the foreign universe.
She hated them more than anything else and wished to wipe out their whole universe. They were the ones who cursed her son, and she would never forgive them.
She knew that her son had a hard time due to the curse, and she was even in more pain for not being able to be with him.
Thus, she was happy to know that her son received such a big blessing from a higher universe.
Without knowing the stir that he had provoked to the strongest members of his universe, Yale continued to upgrade his sword. The sword was already at the Essence God level, and Yale already turned into an Essence God in the Smith Essence, but he hadn't stopped.
Although it was still impossible for him to make the sword surpass the Essence God level, it was possible to make it reach the peak of such level.
No one in the hall of the royal palace noticed the flow of time, but after a few hours, Yale finished improving his sword, and the enlightenment also ended.
Yale had already assimilated all the information he obtained from Tofesh and knew the effects it had on him. He wanted to check the Last Wish system to confirm them, but she was more eager to check his sword.
The sword flowed towards Yale, and he immediately appraised it with his Divine Eyes.
"Essence Slayer Sword: A sword created and improved with methods surpassing the universe where it was created. It can merge with any Essence and had the power to destroy Essence-based attacks. All the properties of the previous version of the sword, Space-time Judgement Sword, are still available."
Yale started to laugh when he read that description. The upgrade had been a success, and the sword turned far better than how it was previously.
The Essence Slayer Sword was a sword at the peak of the Essence God level, which was the same as saying that was at the peak of the weapons crafter in his universe.
Lina and the Dwarf King ended their enlightenment at the same time as Yale since Yale was the one who provoked those two enlightenments, so they weren't pissed off when Yale started to laugh.
