“All signs indicate that the black seawater is a part of the endless sea. The seawater has been polluted, which is why it has turned black.” “The news of Drowning City revealed that the secret realm of drowning city is merging with the Black Sea. This name makes me very uneasy. Could it be that there is black seawater in the Black Sea?” “Also, why did the Endless Sea suddenly appear here? Or is there a powerful race behind it?” Lin Xuan frowned deeply. The more information he read, the more dangerous he felt. It seemed that some extremely powerful alien race was eyeing Earth covetously. They had devoured the cultivation world where the Kunlun Palace and the Heavenly Dragon Temple were located, and they had also devoured the forty-five worlds controlled by the sea tribes. Now, he was interested in the small earth. Something was wrong! The earth was pitifully small compared to both the cultivation world and the Sea clan’s world. Why was the other party so obsessed with the earth? Lin Xuan couldn’t figure it out, but he knew that these things would be very useful. After telling Ji Ruyue, he should be able to get more information based on the other party’s experience. At this moment, Tian Yucai’s joyful shout interrupted his thoughts. “Lin Xuan, Lin Xuan! The Sea tribes are so powerful! They have developed such a powerful mechanical weapon!” Tian yucai dragged him to a drawing and exclaimed in surprise, “Look, they are also studying the defense tower. This kind of defense tower is even better than the one that Chief Wan and I developed together “It can absorb all the energy in the environment to recharge itself. Besides, the efficiency of the energy transmission and the efficiency of the work are both ridiculously high “I think this will definitely be a huge disruption for our construction division!” Lin Xuan coughed lightly. “How many resources will be consumed to build the defense tower according to this method?” Tian yucai was stunned.”…” Lin Xuan said, “How many level eight warriors will be trained with these resources?” ”…” Tian yucai scratched her head in annoyance. “I didn’t think about it.” “As a technician, it’s understandable to research bigger and stronger machines, but you should also think about the consumption.” “If the materials needed to build a machine are even more than a warrior of the same level, then this is a useless machine,”Lin Xuan said with a smile. Tian yucai pouted. “I know, I know… Why are you nagging like President Wan…” Lin Xuan couldn’t help but laugh. “Oh right… I found a potion blueprint in this pile of mechanical drawings. The people of the sea tribe must have put it in the wrong place.”Tian yucai pointed at the huge blueprint under Lin Xuan’s feet, “Look, aren’t you a pharmacist? Maybe you have some insights.” Lin Xuan looked down and saw a few big words. Black Sea water purification potion. Lin Xuan exclaimed and looked at it carefully. “This potion was proposed by the third daughter of the Sea King. It aims to purify the Black Sea water, but it failed in the end…” After reading the description, Lin Xuan became more interested. It seemed that the royal family of the Sea clan was not all drunk and debauched. Looking at it carefully, Lin Xuan did not understand why the potion failed for a short time. However, when he unintentionally connected the Black Sea water of the endless sea with the Black Sea, and the strange black-spotted old men of the Salvation Society flashed through his mind, all his thoughts were immediately connected. “I’ve thought of it. It’s the power of aging!” Lin Xuan was delighted. The third daughter of the Sea King was not wrong. Her mistake was that she only thought of purifying the Black Sea water, but she did not expect that the Black Sea water not only turned the dead people and beasts into zombies, but also contained the power of aging! “If I want to dissolve the power of aging… I have to rely on spiritual energy!” Lin Xuan was even more delighted. This purifying potion only lacked the power to dissolve aging. Spiritual Energy was probably the last step of the potion! “Thank you, the third daughter of the Sea King. Although I don’t know your exact name, everything you did back then helped us.” Lin Xuan sighed softly. If this person had thought this far back then and found a way to restrain aging, he wouldn’t have been so happy. Perhaps the entire sea clan wouldn’t have been wiped out. At least some elites would have escaped and rebuilt the sea clan’s civilization elsewhere. “What did you see? Why Are You So Happy?” Tian yucai asked curiously, “What kind of powerful potion is it?” “It’s a purifying potion. Maybe it will have a great effect on the construction division.” Lin Xuan said seriously. Tian yucai was surprised. She didn’t expect that the potion blueprint she had unintentionally found could be so useful. “Wait… What’s That Thing next to you? !” Lin Xuan suddenly noticed the four-meter-high and ten-meter-long mechanical creation next to Tian yucai. The mechanical creation was green in color and looked like a giant wolf. It was huge and strong, exuding a powerful aura. Lin Xuan used a high-level observation skill to take a look, and was even more surprised. —— Name: Marine Mechanical Giant Wolf (modified) Level: Tier 8, Level 7 Quality: Purple Epic Effect 1: when injured, it can quickly recover through absorbing energy core. Effect 2: Movement Speed + 50% . Effect 3: when receiving fatal damage, the pilot will be ejected and self-destruct. Description: this item was originally a mechanical mailbox of the sea tribe. After being modified by sky feather color, it has turned into a giant mechanical wolf. —— Sky feather color patted her chest proudly, making the sound of steel plates. “Amazing, isn’t it? This is a giant mechanical wolf that I modified with the help of the mechanical parts here!” “Moreover, the firmness of the parts of the sea tribe is very strong. The HP and armor of this giant mechanical wolf are very high!”
