**Chapter 1337: Reviewing the Battle, Estimating Combat Power**
The Tree of Death let out a hoarse and unpleasant scream. From the start of the battle until now, this was the first time Lin Moyu had heard the Tree of Death's scream. He knew that this time, it was truly hurt at its core. Whether it was the vines, the bark, or the roots, they were all just superficial wounds to the gigantic Tree of Death. Only the tree core was its true weak point. Even if all the vines were burned and cut off, it wouldn't be as effective as stabbing the tree core with a sword. However, the tree core was usually hidden inside the tree, protected by thick bark and tree flesh, making it very difficult to damage.
It was only during the continuous self-destruction of the Stone Demons that the tree core was exposed. The Fire Lich drilled into the tree core and started a fire. The projection of the Law Star River in the sky poured flames into the tree core as well. The entire Tree of Death instantly turned into a tree of flames, with firelight shooting up tens of thousands of meters into the sky, continuously burning. Subsequently, the flames began to spread from the tree trunk to every branch, every leaf, every vine, and all the roots.
Lin Moyu could feel the aura of the Tree of Death weakening rapidly. However, it was still making its final resistance. He could see a large amount of life-filled clear water being absorbed by the Tree of Death, also entering the tree core, attempting to extinguish the flames. Lin Moyu chuckled, "Let me send you off on your final journey." He raised his bone sword and charged into the hollow of the tree trunk. He drilled through the tree trunk like a drill, from the bottom to the top of the Tree of Death, tearing the entire tree core to pieces.
The Tree of Death let out a mournful cry, its branches drooping powerlessly, the flying vines all falling silent, and the roots ceasing to move. Its vitality dissipated, and it met its death. Seconds later, the massive body of the Tree of Death turned to ash. Two items fell from it. Lin Moyu picked them up; one was a key, a key to the deeper regions. Soul power flowed out, activating the key. The key disappeared, and Lin Moyu felt a subtle aura on his body, indicating that he now had the qualification to enter the deeper regions.
The other item was a yellowish-brown tree branch. The branch was about the thickness of a thumb and about thirty centimeters long, containing strong earth laws. Using detection techniques, as expected, yielded no results. The Yellow Sand Desert was formed due to chaotic rules, and items from chaotic rules generally did not yield results from detection techniques. Lin Moyu pondered for a few seconds and put it away. He originally wanted to use it to summon the Elemental Lich, as he observed that the branch was of high quality. But after thinking it over, he decided not to.
Since it was dropped by a leader monster, it might be useful later. Just like the crystal cores dropped by previous monsters, which were useless in the outer regions but necessary for summoning leader monsters in the middle regions. So, the material dropped by the leader monster might be useful in the deeper regions. After the leader monster died, the sky returned to normal, the fireball once again became the ruler, and the earth was covered by yellow sand again. All traces of the previous battle were erased, as if nothing had happened.
Lin Moyu stood in the yellow sand, not heading towards the deeper regions yet. Purple light flickered on his body, and his soul had just recovered from collapse. During the battle, he had raised his realm to the ninth rank of the God King, putting immense pressure on his soul. If not for the high quality of his soul, it would have collapsed on the spot. After the leader monster died, Lin Moyu retracted his original spell, and his soul finally couldn't hold on and collapsed. Under the talent, his soul recovered, and he also gained a strong soul power. This was the soul power absorbed from the leader monster by the original spell.
At this moment, the Talent Giant Tree and the Nine-Colored Dragon Soul Crystal were frantically refining and purifying this soul power, which would soon be sent to Lin Moyu's soul. Lin Moyu closed his eyes and pondered, reflecting on the battle process. Without a doubt, the Tree of Death was the strongest enemy he had encountered, giving him the illusion of fighting a boss in a dungeon. Lin Moyu reviewed the battle process, checking for any mistakes and considering if there were simpler ways to deal with similar enemies in the future.
He still had a mortal enemy, no, more than one. The Starry Sky Giant Tree and the Zerg were both his great enemies. Lin Moyu believed that sooner or later, they would meet. Using the Tree of Death as a reference, he might be able to analyze the weaknesses of the Starry Sky Giant Tree. "I was too conservative before, losing my original intention." "Even a lion uses its full strength to catch a rabbit. I didn't do well in these two points." "If I had used all my strength from the beginning, including the Stone Demons, myself, the Skeleton King, and the Lich, I might have caught the Tree of Death off guard, giving it no chance to respond."
"If I had known from the beginning that the Tree of Death's weakness was the tree core, I could have attacked the weak point directly." "My combat methods are not perfect, and my knowledge is not comprehensive. I need to review the information and improve my knowledge base when I return." "At the same time, I lack high-end combat power. Without the Stone Demons this time, it would have been difficult to deal with the Tree of Death." "But how can I improve my high-end combat power?" "Fusion spells... maybe I can start from this aspect."
"I also need to collect some high-level starry sky giant beasts or alien flesh for future use." After reviewing the battle process, Lin Moyu also evaluated his combat power. Ordinary ninth-rank God King monsters were not difficult for him to deal with. Whether it was himself or the Elemental Lich, they could easily handle them. Especially with the cooperation of the Starlight Lich and the Fire Lich, they could kill almost any ninth-rank God King of any race. But if he encountered a leader monster in the deeper regions, it would be beyond his reach.
Even the Tree of Death was so difficult to deal with, the leader monsters in the deeper regions would definitely be at the ninth rank of the God King, with real combat power close to a Minor God Sovereign. Plus, with the vitality of a leader monster, it would be difficult to deal with even with all his means, unless he used his life-saving trump cards. However, to penetrate the deeper regions and enter the deepest part of the Yellow Sand Desert, he must defeat the leader monsters inside. "No wonder only Minor God Sovereigns have a chance to enter the deepest part."
"And even one Minor God Sovereign might not be enough. Back then, Xu Qingyang might have teamed up with several Minor God Sovereigns to achieve it." "But he couldn't bring out the news, leading to others' misjudgment, not knowing the specific situation inside." "With my current strength, there is still a gap. It seems I need to improve my strength further." Lin Moyu thought that if he could advance to the ninth rank of the True God, he might be able to deal with the leader monsters in the deeper regions alone.
As he was thinking, pure and vast soul power poured in. His soul felt a burst of warmth, like entering a hot spring, and began to grow rapidly. His aura quickly strengthened, and his realm took another step forward. The soul power given by the leader monster was abundant, and after Lin Moyu absorbed it, he was not far from the ninth rank of the True God. "According to the calculation of soul power, I only need to kill five or six hundred eighth-rank God King Earth Giants to advance to the ninth rank of the True God."
"But this way, my control over the laws might be insufficient." "There's no other way, I'll make up for it later." After resting for half an hour, Lin Moyu held his bone sword and walked towards the Earth Giants.
