After they went through some corridors, they gathered all kind of information about the liquid and the CEs. It said that it all had their origin from the lord. The lord created them, so he could, in the future take over Broly's body.
He left behind an energy ball which could grant life to creatures specifically for gathering lifeforce. The lifeforce collectors would kill and steal as much as lifeforce as they could until they were defeated or intentionally destroyed, as they could only increase to a certain level of strength. The lifeforce they had gathered until that point would automatically gather to a lifeforce pearl. This pearl would be attracted to the soul pearl that was placed inside Broly's body and in the end merge with it.
The soul would need a tremendous amount of lifeforce to heal the soul and awaken it. If it manages to awaken, the lord would be able to take over the body he was in, no matter how strong the host is. The mission would have succeeded by then.
Broly could feel the confidence the lord had as he read those claims. Fortunately, the soul didn't account for the fact that Broly could manipulate lifeforce and make the lifeforce pearl his own.
It seemed that after it entered his ki center, Broly accidentally broke the pearl and pulled it's fragments into his own source, essentially making his own pearl out of the parts.
Theoretically he should be able to fuse the pearl with his soul as well, making it even stronger, but Broly didn't how he could accomplish that, as he doesn't have a clear idea how or where he should fuse it to begin with. There wasn't much information about it on the instructions. It wasn't needed, as it would have been an automatically process.
The green pearl seemed to be only hardly moved by his manipulation or his ki. For now, he would leave it alone. He wanted to let his body rest and digest the energy it got.
Broly went into, what seemed to be the Saiyans bedroom. He searched the room for any additional notes and he found it after a while.
'Under the bed are you serious? A diary, just wow.' Broly read the diary while waiting for the others to complete the search. What he read about astonished him.
It starts with him deify this lord. Apparently, that lord was a really old and mighty Saiyan. He even compared his lord with the gods of the destruction and their angels. He wrote that there were few that could match him and was only able to be deadly injured because he was ganged up by the gods.
They seemingly had feared him for his strength and his viciousness, which made them come together and fight him to the death.
Broly furrowed his eyebrows as he read this.
'There was never anything mentioned in the series about such a terrifying enemy. The lord was also referred as the true Saiyan god, which would point to Yamoshi but it doesn't make sense. Why would Saiyans still exist if the gods feared one of them this much? Why would they let Goku and Vegeta live with the strength they will show in the tournament of power?
Broly shook his head in confusion.
'If it really is Yamoshi then maybe I inherited his powers and that's why I am the only one that he could take over. But what about Kale, isn't she a Legendary Super Saiyan as well? Didn't he know about her? And how the fuck does he even know about me? Isn't he a Saiyan from ancient times, how is he still alive and has followers? Well it is all assuming that it is indeed Yamoshi, but what if it isn't? Maybe what he wrote didn't happen yet. Ah shit. Fuck this! I can't get an answer now, maybe if I am able to interact with the gods, I will get more information. But this shows me that I can't fully rely on only what I saw in the series. This universe probably holds much more than I ever saw in a TV series.'
With this thought in mind he read through the whole book. The Saiyan wrote about the fact that he specifically used this planet as the space and time around it was messy. It made it easier for him to kidnap other races to this planet, as it would make him less detectable for the gods, making it easier to evade their senses. He also used the broken space to connect to other places with broken space as well. He would guide them through the clouds rift to this planet and then let them procreate so he would have an endless supply of strong races with much lifeforce, he then fed the lifeforce pearl with.
He was also the one that delayed Broly's arrival, as long as he could, so he wouldn't become too strong. Broly's strength he had now was actually pretty close to the Saiyans estimation. Unfortunately for him, he didn't account for the Mother Blood Crystal Broly consumed, granting him the ability to steal the very lifeforce which was meant to heal the soul.
It was also stated that the Saiyan used a portion of his lords' power, but he didn't know what exactly he used, since there was nothing extraordinary on the corpse.
'He really wrote all of it down obediently but failed to mention his lords name. He obviously never expected to fail, but why leave something like this out? Well, he also left out how he got to learn about this ancient Saiyan and how to revive him. Probably just played it safe.'
After an hour they were done with searching and were ready to go. Before they went to the entrance, Broly rushed through all the white corridors to double check if there were any CEs in hiding and killed them one by one. Thereafter they went to the cave's tunnels and then out. When they flew out of the cave, some of the Saiyans kneeled down and touched ground letting the earth crumble between their fingers. They had lost their control years ago, it was understandable that they wanted to relish the moment. Some also showed their will to fight, as some of them began sparring against each other.
They were much stronger than any other Saiyans without the Super Saiyan transformation, which Broly inferred from there changed bodies. Although they were much stronger, some parts of them were completely black with the liquid. Broly didn't know if they could take out this black liquid to prevent any side effects like them being controlled in the future.
"Alright. We will leave to our current headquarters. Follow me!"
Broly flew up with the group in tow. After distancing themselves for a bit, he looked back and had someone throw a lifeforce sphere into the entrance of the cave. After a moment of silence, the whole thing blew up erupting in a massive explosion, completely obliterating the ground of the upper levels of the cave.
The corridors and the Saiyans bedroom were unaffected by this, as that part was created with an incredible tough material. The ones with faces were more intelligent than their counterparts without faces. He didn't want to go through all side-caves to kill them one by one, so to prevent any troubles in the future he wanted the whole place blown up and killed any CE that tried to escape.
