A few days later. A certain area of ????the Blade Sea. An Rui and Croya were sneaking under the sea, each holding a huge bubble on their head. After these days of nursing, Croya's injuries have been mostly healed and he can move freely. Both of them wore luminous stones, which emitted a white halo and illuminated the darkness under the sea. There are a large number of sea monsters and carnivorous fish lurking around. These sea creatures circle around the two of them, and from time to time some bold ones will rush up to attack them. The marine creatures here are very powerful, and it is difficult to suppress them with Longwei alone. Whoosh! Another sea monster rushed over. It had a slender body, covered in silver light, and the fins on its back were as sharp as blades. It quickly rushed to An Rui's side, swayed, and used its sharp fins to paddle towards An Rui. Even though this is just a fin, its sharpness is no less than a gold-level weapon. An Rui was short and dodged the blow. Then he swung his backhand and struck the sea monster in the head with his sword. The sea monster was hit by a sword in the head, and a stream of blood spurted out, killing him on the spot. An Rui didn't see any movement, and the bloodthirsty sword he swung had returned to its scabbard. "Okay, let's keep going." An Rui pointed downwards and continued diving. "President Anrui, how long do we have to swim to find the 'ancient tree in the center of the earth'?" Croya asked. It can be seen from his title that he has surrendered to Anrui and became a member of the Overlord Chamber of Commerce. ¡°It¡¯s almost there, we¡¯ll be there in another three to five minutes of swimming.¡± An Rui replied. The two of them went on this trip to find a tree called the "ancient tree in the center of the earth", which grows deep underground. It doesn't need sunlight to grow, and it lasts a long time. Therefore, it is called the ancient tree in the center of the earth. This kind of tree is quite spiritual and has certain wisdom. If danger comes, it will take the initiative to fight back. Its branches and the sap it spits out are powerful weapons. The reason Anrui wanted to find this kind of tree was to improve Croya's strength. ? ? Croa is a druid who is very good at controlling plants, especially trees. That's why he got the nickname "Tree King". With the druid's magic, he can control hundreds of trees to fight for him, turning the trees into powerful soldiers. Trees are different from tree to tree. There are strong trees and there are weak trees. The stronger the trees Croya controls, the stronger his combat power will be. The ancient tree in the center of the earth is a kind of powerful tree in the area of ????the Blade Sea. The strongest tree that Anrui can find is the ancient tree in the center of the earth. He wants to find this kind of tree and help Croya improve his strength. In this way, Croa can also come in handy when the Imperial fleet attacks Red Diamond Island in a massive attack. The two continued downstream and passed through a large group of mountains standing proudly on the seabed. These mountains dived to the seabed due to changes in the earth's crust. If these mountains rose to the sea, they would be thousands of yards high. These mountains hidden under the sea are completely different from the mountains on land, and they have a different scenery. Many marine creatures inhabit these mountains, moving in and out of caves and crevices. There are some huge ones among them. The two passed through the valley on the bottom of the sea and reached the deepest part. Then it stopped. "We're at the place. The ancient tree in the center of the earth is down here. Let's dive into the ground together." An Rui was hanging in the turbulent sea water, looking at the land below with burning eyes. Croya did not ask why Anrui knew there was an ancient tree in the center of the earth below. Years of experience as an official taught him to do more and ask less questions, and not to question leaders easily. "Leave it to me to sneak into the ground." Croya took on this important task, swam to the surface, dug out the moist soil, and planted a seed. Anrui could easily sneak into the ground using the diamond ring, but he did not stop Croya, but watched quietly from the side, wanting to see what tricks this new subordinate was playing. Croya stretched out his hand, aimed at the seeds in the soil, and cast a spell that had the effect of accelerating plant growth. A soft green light emitted from the palm of his hand, and the light revealed a rich breath of life, just like the spring sunshine and the Rain and dew. Under the influence of the spell, the seed quickly took root and sprouted, growing rapidly at an alarming rate, sprouting rhizomes one after another. These roots are like the powerful tentacles of the octopus and sea monster, piercing into the soil and extending downward. A jar of soybeans soaked in water can even burst a glass bottle. The power of plants cannot be underestimated. The rhizome tentacles continue to extend, penetrating deep into the ground, opening up a path to the bottom. The tentacles continue to grow and thicken, tearing and squeezing the soil below, causing the passage to continue to widen. The surrounding seawater poured in and filled the channel. The channel extended downward and became deeper and deeper. After diving for more than a hundred yards, it finally penetrated the land. The plant tentacles extended into an empty and unknown space below, and the surrounding seawater surged at a sudden speed, forming a torrent. "There is actually a cave below." Croya said in surprise. Due to the influx of sea water, it is not yet clear what is underneath. Judging from the flow rate of sea water, the space below should be very large. An Rui looked at the passage made of plants and nodded slightly. Different professions have different abilities. Druid's ability to transform into animals and control plants is still very strong. "Okay, let's go down together. Down here is the ancient tree in the center of the earth. I don't need to remind you how dangerous this tree is. Just remember to be careful." An Rui warned and got into the passage first. Dive quickly with the current. The distance of one hundred yards is not long. An Rui quickly passed through the tunnel and came down below. The space here is very large. Looking at it, it is at least three thousand yards long and wide. Above this space, a towering tree grows, and the tree extends downward, spreading out dense branches. The color of the bark is gray-black, almost like the color of stone. There are no leaves on the branches, but there are many buds. Sea water continuously fell from above and poured into this space, forming a water column, which could not be filled in a short time. Croya then arrived and hung in the air using a flying cloak that An Rui had given him before. He saw the strange giant tree growing underground and said excitedly: "There is actually an ancient tree growing here!" The motionless branches began to tremble slowly, reaching towards An Rui and Croya. These branches have different thicknesses. The thickest part is three times thicker than an elephant's waist, and the thinnest part is as slender as a little finger. "Cloya, how long do you think it will take to conquer this big tree?" An Rui drew out his swords and asked attentively. Croya recovered from his stunned state, and after thinking for a while, he replied: "If you can let me get close to its roots, I can subdue it in just one minute." "Okay, I'll help you. Fight for this minute, come with me!" As soon as An Rui finished speaking, he rushed towards the ancient tree in the center of the earth, as fast as lightning. Croya followed behind, casting a defensive spell halfway, and a layer of wood-skin armor spread out from his body to protect himself. The rapid movement of the two people further touched the ancient tree in the center of the earth, causing the tree to react violently. Countless branches rushed towards the two people at high speed, trying to tie them up. The two tried their best to avoid these branches and looked for a way forward through the gaps. "Shua!" A branch was like a whip, whipping An Rui hard. An Rui mustered up all his strength and struck the branch hard, causing the branch to break. The ancient trees in the center of the earth have very strong defensive capabilities. Even he has to use all his strength to cut off these branches. If he encounters branches that are too thick, he will not be able to cut them off with just one sword. The two of them flew all the way and gradually approached the trunk of the ancient tree in the center of the earth. The ancient tree in the center of the earth was completely anxious now, and began to deal with the two of them with all its strength. All the branches on the whole tree moved together, half of them were wrapped around the trunk for protection, and the other half attacked the two of them like crazy, and used Another way of attack. Countless wood buds bloomed on the branches, revealing small black holes, which were aimed at An Rui and his wife. "Chichi!" The black holes spattered red sap. The sap has a strong corrosive effect and can easily corrode even metal and stone. Fortunately, Anrui had already prepared and brought defensive treasures for himself and Croya. The two of them each stretched out their magic scrolls and formed a layer of water curtain around their bodies. The sap sprayed on the water curtain and immediately slid down without causing any harm. The two of them used various means to resist the attack of the ancient tree in the center of the earth, and finally rushed to the big tree. An Rui suddenly swung the Demon-Breaking Sword, using the magic power contained in the sword body and integrating it with his own power, increasing the destructive power of the blow. He slashed hard at the root of the tree and split several strands wrapped around it. branches. The damaged tree roots were exposed, and sap as red as blood emerged. Seeing this, Croya quickly flew to the side, reached out and aimed at the roots of the tree, and released the spell used to subdue the plant. Green luminous symbols appeared in the sky and were printed on the roots of the trees, making a buzzing sound. This kind of surrender takes a minute and cannot be successful in a short time. During this minute, Croya cannot be disturbed in any way. Anrui holds two swords in his hands,Floating next to Croya, staring at the surging branches around him, he tried his best to protect Croya from being affected. The ancient tree in the center of the earth has a certain thinking ability and can make judgments based on the surrounding situation. When ordinary attacks have no effect, it can only use its trump card. Many branches were tangled together, and their size continued to expand, as if they had turned into a giant's fist. The giant fist of this branch is accumulating strength, and the branches make a tight creaking sound.
