Lord of the Truth

"Did you just say you are going to nullify my return to Earth effect and make me a Treant again? Do you even realize what you're saying?!" The Tree Father avatar spoke quickly, it was clear that Robin's offer this time hit a nerve

"I have an idea about the matter from the memories of your friend Hoffenheim, If I remember correctly Returning to Earth can be described as a union with the planet. You used your true nature to unite with the planet to become mere trees once again. You can no longer be considered living beings like the rest of us but you have become an extension of the planet itself. This is why your bodies have been able to reach those heights even touching the high sky, this also gave you a lifespan of no less than half a million years and no more than 700,000 years. This means that there were other ancient Treants other than you who died of old age in the era before energy cultivation," Robin pointed towards the avatar and spoke slowly, "But after you started energy cultivation, your bodies became much stronger, your souls became unfathomable, and the entire energy of the planet is focused almost solely on the seven of you, and the minor heavenly laws that you lot trained on and related to the path of life are countless, so your life span has increased significantly. I believe that your life span has now reached around 2~2.5 million years, right?"

Then Robin added, "This is too much if you want my opinion. Most beings, especially humans, forget what happened a few years ago, and their feelings change a hundred times a day. I honestly cannot imagine living for millions of years, and also on the same planet. No, no, In the same spot actually since you couldn't move even if you had the whole planet to yourself! I asked Hoffenheim the same question before and I'll ask you now... Why do you even live? What would the planet's spirit give you that would be worth doing all this for? A little longer lifespan? More power? or the ability to move again? I can't think of a third option."

Robin shook his head with a half-laugh, "If it is one of the first two choices is correct, don't you think this is a joke? What will you do with a longer life or greater strength while you are nailed to the ground forever? The time will come when you want to commit suicide will not be long. But if your goal is to move and talk again, then this is more understandable. I can help you, and you will not need to wait for hundreds of thousands or millions of additional years until you succeed in your endeavor. What do you think?"

"...Robin Burton, you said yourself that our bodies have become one with the world. We are now like mountains, rivers, and plains. Have you ever seen a mountain move?" Father Tree Descartes was silent for a few minutes before he asked again without conviction

"I'll understand from this that even controlling the planet's spirit won't change your fate as a tree father? Haha, ridiculous, what are you even fighting for then?" Robin laughed sarcastically, slapping his thigh

"..." The tree father avatar did not say anything, he just kept looking at Robin silently. It was clear that he was trying to remain calm, but the avatar's hands were clearly shaking.

Robin gave him a chance to process what he had heard first, then spoke again, "Descartes, you are not an ordinary person, but rather an entity who lived for hundreds of thousands of years. You have experienced an entire life as a treant, then you have experienced union with the planet, and you have entered into wars and massacres that have not subsided to this day. I know that your age and your experience have given you some knowledge, so make good use of it. If this meeting ends before we reach an agreement, you will be the losing party."

"...What makes you so sure that returning to Earth can be nullified?" After a long time, the tree father finally opened his mouth

"I have the Major Heavenly Law of Life and the Major Heavenly Law of Earth and I have the ability to see soul patterns, what more could I possibly need? More Major Heavenly Laws? More advanced stages of those Laws? These are all things I will reach sooner or later, you're not in a hurry, right? You were nailed in your spot for who knows how long, haha, I've been in your shoes, it won't be a problem if you wait a few more years." Robin replied confidently

The Tree Father avatar remained silent for a few minutes, and then another question appeared in his head that he hurriedly mouthed, "What about my lifespan? I already far exceeded the maximum that a normal Treant creature could live. Won't I be exposed to death as soon as the return to Earth is nullified?"

Robin waved his left hand, "I will not allow my subordinate to die so easily. Perhaps your remaining life will not reach the 2.5 million years that you have now, but living for a few tens of thousands of years will not be a problem. After all, you are still a plant, and extending your life is quite an easy matter, The same life energy that gives humans a week of extra life can give you a few years! After you acquire the fourth stage of the Major Life Law, you will have no problem increasing your life until you get tired of it."

Descartes was silent again for a few minutes, then finally he seemed to think of something and shook his head and spoke, "…Alright then, when you invent that technique that nullifies the effect of returning to Earth, I will swear allegiance to you."

Robin shook his head, "This won't work, now or never."

"Robin Burton, don't be unreasonable here! Do you want me to swear allegiance to you without giving me anything in return? To swear allegiance to you means to give you all the information I have without conditions and fight under your orders without complaint. In return, you are selling me fish while it's still swimming in the sea?!"

"Descartes, the Fifth Legion fought in the lands for almost six years. You must know about the Oath Tablets, right? Even Hoffenheim knew about them and did research on them, and I do not think that you are any less intelligent than him. Since you are the ones who came to me on your own, I will not insist on placing the soul inslavement seal on you, all you have to do is swear on one of those tablets, and as soon as you swear allegiance to me on one of the tablets, I will give you techniques to strengthen the soul and give you all my experiences about upgrading your soul from white to silver, and I will also give you the Major Heavenly Law of life up to the third stage, and in top of that I will also swear Also on an oath tablet that I will give you the fourth stage of the Major Heavenly Law of Life and the method of canceling the return to Earth when I finish with them." 

Robin straightened up in his posture and spoke seriously, "It does not require a lot of intelligence to know that I will not break my promise. After you swear allegiance to me, it is natural for me to try to strengthen as much as I can so that you serve me better. What benefit will you do to me while you are stuck in your place? Maybe help me fight against the rest of the Tree Fathers and the human tribes? I can take care of them on my own. You have to understand, Descartes, Planet Greenland may be everything in your view but it is only another way to resources and training forces in my eyes. You may only be of use to me if I take you to other planets!"

"Me? I can go to worlds- no, to other planets?!" The avatar of the tree father opened his eyes made of paper to the end. If the avatar had a heart, Robin would have heard it beating like a drum.

Robin didn't respond with more words, he just nodded and smiled

"..." The tree father avatar closed his eyes and sat there, clearly entering a state of deep thought

Robin didn't bother him either and leaned his back completely against the tree behind him, while Billy took out the tea set and sat on the side heating up some for himself and Robin.

The three suns in the sky are always working hard to make sure that Greenland always has light. There is no night here so it is difficult to follow the flow of time if you are inattentive.

After an unknown time, the Tree Father Avatar opened his eyes, "Give me the Oath Tablet."
