Liu Xin didn't look at the things behind him at all, and directly exchanged his only level 4 energy for an elixir that increased his lifespan by 100 years.

"Teacher, eat it, the world is still waiting for you to recover!" Liu Xin smiled and handed the black longevity pill to Leo, and Leo was not polite, and ate it directly.

"Uncle Oran, how many feats can you change the ears of these monsters?" Liu Xin looked at Oran next to him again, and poured out a large number of monster ears, while Oran looked at the mountain-like monster ears on the ground in surprise.

"Well, there can be two choices, the first is to exchange for the Success Medal, you can get a title, and the other is to exchange it for gold coins, what do you need to exchange?" Oran asked Liu Xin with a smile.

"Well, then help me exchange 1999 gold coins, and the rest for titles!"

"Okay, Liu Xin, because you performed well in the battle of monster invasion, kill the 3W monster, and first award you the title of Kaigu Patriarch!" Oran took out a holy book and said to Liu Xin solemnly.

"Ding, the host gets the title, Kaigu Patriarch, this title can command a 30W army in the Dragon Nest world, the status is equivalent to the king of the current dynasty, and it can be respected by the Dragon Nest NPC, and it is invalid to use in other worlds."

"Why is it called Kaigu Patriarch?" Liu Xin didn't expect it to be this title, this title is the rarest title in the play.

"In honor of the ancient dragons, we have decided that this world will be called the Valley of the Dragons from now on, and the ancient dragons will be with us." Oran said solemnly, Liu Xin also remembered the ancient dragon who sacrificed himself in order to protect the continent, and nodded seriously.

"My lord, this is your gold!" A guard came to Liu Xin's side with a big bag and said respectfully.

After Liu Xin took the gold coins, he directly exchanged all the gold coins on his body into energy points.

"Ding, the host has exchanged 4,000 gold coins and obtained 4 points of level 4 energy, I hope the host will continue to work hard."

"Exchange for 3 longevity pills." As soon as Liu Xin's words fell, three black pills appeared in Liu Xin's hands.

"Uncle Oran, Uncle Andy, it's yours. Eat it, brother, help me find Ida from the elite team. Liu Xin handed the two longevity pills to Andy and Oran, and asked the guards next to him to help him find Ada.

Soon Ida came to Liu Xin's side, and Liu Xin smoothly fooled a few people into taking the pill, but did not tell them what the effect was.

"Okay, when the time comes, I'm going back too." After Liu Xin asked the four of them to take the pill, he stood up directly and walked to the square in the center of the holy mountain.

"Teacher, it's time, it's time for me to go back. Take care, I'll be back to see you! Liu Xin looked at the familiar crowd around him, a little reluctant, but Liu Xin knew that the main world was where he should be, his parents were still waiting for his resurrection, and the dark side was still waiting for him to control, so he couldn't spend all the time in this Dragon Valley world, so he gritted his teeth and held back, not letting his tears flow out.

A gust of wind blew, and the entire crowd in the square was blown to the left and right, and above the sky, a space began to shatter, slowly turning into a pitch-black hole, and electricity was constantly bubbling around the hole.

"I'm leaving. Take care, everyone! Liu Xin looked at the familiar face again, and resolutely turned around and entered the space hole.

"Salute!!" Oran watched Liu Xin turn around and yelled directly, while everyone around him made a fist with his right hand and placed it on the left side of his chest, solemnly watching Liu Xin leave.

If it weren't for Liu Xin, the war between humans and monsters might have lasted longer, and more people would have died; If it weren't for Liu Xin dragging the Shadow Dragon, maybe the Shadow Dragon would have been destroyed when it was born; If it weren't for Liu Xin catching up with the Chaos Dragon, maybe the holy mountain no longer existed, and Liu Xin deserved everyone's salute.

As Liu Xin stepped into the space hole, the familiar feeling of weightlessness spread throughout Liu Xin's body again.

"Whew, it's finally back, the familiar smell of industrial pollution." The place where Liu Xin returned was the same place where he entered the world of Dragon Nest, and there were still corpses of team members who had fought in a civil war to compete for the first place to enter.

"Rhapsody, how long has it been in the Overworld?" Liu Xin also wanted to determine how long he had been gone, although he didn't know much time, it was better to know the specific time.

"Seventy-two hours have passed in the Overworld."

"72 hours? Not much, old man, I'm back! Seeing that there was not much time in the past, Liu Xin didn't have too much entanglement, and directly called the sword of the Brotherhood in his heart.

On a mountain in the distance, the sword of the Brotherhood stuck at the top of the mountain shuddered, but it was bound by the chains and various things around it.

"My lord, it moved. Our raw steel chain is running out of control. A man in a white coat who was observing the sword of the Brotherhood ran excitedly to the side of an old man and said.

"What? That sword moved? He must be controlled, maybe he is related to a new substance, quickly, let Xiao Zhao and them go, and he must not be allowed to run! He must be our Yang family, hurry! The old man, known as the Adult, quickly gave orders, allowing those around him to increase their control over the Sword of the Brotherhood.

With Liu Xin's call, the struggle of the Sword of the Brotherhood became more and more intense, and the chains that restricted the Sword of the Brotherhood around were broken one by one.

"Quickly, continue to increase the original steel chain. Third, help me hold the chain together! A powerful young man shouted to a big man next to him, and multiple chains were once again tied to the sword of the Brotherhood.

"Huh, what's going on? Contained? Who is so bold as to control my sword? Then you can see if you have the ability. Liu Xin also felt the message from the sword of the brotherhood, which contained the longing for Liu Xin and the helplessness of being controlled.

Liu Xin slowly closed his eyes and sensed the direction of the Sword of the Brotherhood. The surrounding scene began to change rapidly, and everything was a blur because of the high-speed movement.

Suddenly, Liu Xin's gaze stopped, overlooking an upper peak. The sword of the Brotherhood was struggling on the top of the mountain, and around the top of the hill were makeshift board houses, in which a large number of researchers in white coats were busy coming and going.

The Sword of the Brotherhood is covered in various chains, and there is a large group of D-Class and E-Class people around it holding on to the chains to prevent the Sword of the Brotherhood from breaking free.

"Humph!" Liu Xin snorted lightly, and his consciousness directly entered the sword of the Brotherhood. In it, Liu Xin saw the sword spirit of the sword of the brotherhood, which was a sword of the brotherhood that had shrunk countless times, and after Liu Xin's consciousness entered, he kept circling around Liu Xin, and Liu Xin's consciousness could feel the joy of the sword spirit.

"Hehe, old man, I'm back, let's get rid of all this garbage around first, and then let's continue to kill the enemy together!" Liu Xin comforted the Sword of the Brotherhood, and the consciousness that entered the Sword of the Brotherhood was directly shattered and turned into pure qi. And after the sword of the brotherhood received Liu Xinqi's support, a large amount of sword qi directly emerged.

The sharp sword qi directly cut off all the surrounding iron chains, and the sword of the Brotherhood also soared into the sky when the iron chains were broken, flying quickly in the direction of Liu Xin.

"Quick, the fighter takes off, catch up with that sword, you must catch up with him, Xiao Zhao, you go personally!" The old man saw the sword of the brotherhood flying, and yelled directly at Xiao Zhao next to him.

A gust of wind swept from far and near, and Liu Xin raised his right hand with a smile. As the wind passed, a dark red giant sword appeared in Liu Xin's hand, and Liu Xin's right hand also happened to pinch the hilt of the sword of the Brotherhood.

"Old man......" Liu Xin looked at the sword of the brotherhood in his hand with a smile, and he could also feel the joy of the sword of the brotherhood.

"Yo, there are still people who don't know whether to live or die!" A fast-moving object appeared in Liu Xin's qi sensing technique, and there were two qi on it, which was estimated to be something like an airplane.

Liu Xin held the sword of the Brotherhood obliquely and rushed towards the high-speed moving plane.

Soon, a better J-10 fighter appeared in Liu Xin's field of vision. Liu Xin's sword was sideways, and he quickly crossed shoulders with the J-10 fighter. Behind Liu Xin, a violent explosion sounded. The entire fighter was cut in half when it passed Liu Xin, and it exploded directly after gliding out for a distance.

"Cut, dare to touch my things, look for death!" Liu Xin said disdainfully as he looked at the rapidly falling fire behind him.

"Boy, you're so ruthless, ahem!" One sentence directly frightened Liu Xin to jump, and there were still people who were able to dodge their qi sensing techniques and come to his side.

Glanced left and right, and found that there was no one around, and the other party could not be sensed in the qi sensing technique, Liu Xin put on a serious fighting posture, and this time it is estimated that he was annoyed by the encounter.

"Ahem, boy, don't get excited, come down, I'm down there!" As the sound sounded, a hill on the ground moved.

Liu Xin also used the qi sensing technique to observe the mountain bag, and finally discovered that the other party was actually Xuanwu, one of the four holy beasts with whom he had a relationship. But Liu Xin could feel that Xuanwu's breath was already very weak, and even the qi that came out had begun to shatter.

"Soap, you ......"

"Ahem, I finally found a qualified person, it will be you kid, ahem......" Xuanwu's weak voice came from the small mountain bag in front of him.

"What about Shanshan? Why didn't I stay with you? Xuanwu asked directly.

"Shanshan? Who is it? Liu Xin asked inexplicably.

"Ahem, you kid! Snow is angry with his daughter!! You, ahem, ahem! Xuanwu coughed violently in anger.

"Eh, you said Little White Tiger, I was separated from him before, but I couldn't sense her, so I don't know where she is now." Liu Xin said with some guilt, after all, it was the white tiger who entrusted him to take care of the little tiger.

"Hey, I can't blame you, ordinary people really can't sense our breath. Ahem, you have to listen to what follows, I'm running out of time. Xuanwu paused for a moment and said again.
