"The predecessors of this great dan wei did not wipe out their own Shouyi after the death point, but found such a polar yin crypt and sealed it. First, it is a warning to those who come after us, hoping that we can think carefully before considering whether to continue to use this technique; The second is to leave research materials, hoping that later generations can solve this strange mystery. Fill in this technique, which has never been complete, and push it to a higher realm. Thousands of years, nearly 20 generations of efforts, we still haven't been able to find the answer

A deep voice echoed through the cold cavern, hands holding the frozen bones in front of them. Xu Jingzhi's face was full of fanaticism. That originally calm appearance seemed to have been disguised with these strange corpses, thinking of some kind of possible Mu Yuchen fell into thought. Xu Jingzhi looked at his disciple quietly. There was a sudden silence in the cavern.

"How? Want to learn? Such an ending is an inhuman alchemy. "At the end of the return. After getting off the residence, Xu Jingzhi asked.

"Of course." There was still no hesitation. Mu Yuchen replied.

Xu Jingzhi didn't want his youngest disciple to embark on the same path as himself, because there was no turning back on this path, and there seemed to be no hope of success; However, Xu Jingzhi also does not want this secret art to be lost, because it is the painstaking efforts of the ancestors of the past generations with their lives.

"That's fine! I'll leave all the secrets to you! Xu Jingzhi's expression became complicated, half regretful and half relieved, but he relaxed after the end.

This kind of very comfortable study day did not last long, three days was enough time for Xu Jingzhi to spit out all those things that had been passed on by mouth. And in terms of Mu Yuchen's memory, these things are also easy to memorize. After the teaching, Xu Jingzhi sent Mu Yuchen into the cave again, where the experience of the predecessors of the past generations was preserved. Let Mu Yuchen face the remains of these predecessors alone, Xu Jingzhi tried to let his disciples give up with the mentality of just in case, but the final decision was still in Mu Yuchen's hands. Faced with all kinds of research notes and refining experiences calculated by the number of bookshelves, Mu Yuchen began to play the cheating function of his visual memory ability, and a certain hunch told him that his time was running out.

After returning to Yunshan for about a week, Mu Yuchen, who had been studying hard and trying his way, received a task prompt from the system one night, and the last three reincarnators entered the world of Fullmetal Alchemist at the same time tonight, and the task of free adventure began.

"The personnel are ready, the mission begins, task one: reach the Central of Amistolis in three days, reward the source milk, and the failure punishment: obliteration."

"Are you leaving?" Xu Jingzhi asked Mu Yuchen, who suddenly returned to his residence.

Since Xu Jingzhi finished teaching the mantra and demonstrated all his experiences. Mu Yuchen stayed alone in the cold crypt. Study the various materials hidden in the depths. This is a path of self-exploration, and Xu Jingzhi herself has only just stepped into it.

"Yes! Master, there are some things that must be done, and I am going back to Amestorius. Mu Yuchen said with some expectation.

"The Philosopher's Stone? Something out of nothing! Xu Jing's old man sighed: "Do you think that is an opportunity to complete the secret technique?" ”

Even if he rejected the temptation of the Philosopher's Stone, the regret accumulated for thousands of years was still precipitated in Xu Jingzhi's mind. This alchemist who stands at the top of the world is still obsessed with the exploration and pursuit of the unknown.

"Maybe!" Regarding Xu Jingzhi's misunderstanding, Mu Yuchen felt that this was a good thing. At least that way you don't have to bother making up excuses.

Even if it is a white lie, in the face of a master who cares and loves him, it is better not to say it or not to say it.

"Then go ahead!" Xu Jingzhi turned his body and didn't let Mu Yuchen look at his expression: "Take care!" Boy, there must be a lot of people going to grab such a treasure! If it's too dangerous. Don't push yourself! ”

Mu Yuchen strode down the mountain, and Xiao did not answer Xu Jingzhi's words, so that his mind should be conveyed! From the day he became a reincarnation, danger has been a common thing for Mu Yuchen!

Being chased by zombies, slashing with martial arts masters, intriguing with reincarnators, and fighting in hordes of illusions, these various things have been integrated into Mu Yuchen's life and have become an inseparable part of his life. This kind of life has made Mu Yuchen accustomed to it, and he has adapted to it peacefully. ,

"I'd really like to split these up!" Putting on Iron Man armor and flying high in the air, Mu Yuchen thought so, and after accelerating to leave a sound of air explosion, he disappeared into the dark sky. "It's a pity,"

A lot has happened in Central in those past years. As a follow-up to the murder of Xiuz, Captain Ross was pushed out by someone from the military department to be a covert scapegoat. Using this as the trigger for subsequent events, Barry, who was secretly hidden by Colonel Mastan, carried out a prison robbery under his command.

In the process of chasing the fugitives, Mastan successfully rescued Second Lieutenant Ross from stealing the beams and changing the pillars. And with the help of Knox, an autopsy doctor who was also a comrade-in-arms of the Ishbaru Annihilation War, he successfully deceived the androids and the upper echelons of the military department with the fake corpse made within the time limit. After the incident, the military investigators played up the personal vendetta of Mastan in an attempt to make the colonel's subordinates betray their relatives.

But what everyone didn't expect was that Mastan actually did the trick and used Barry as a bait to try to lure all the androids out. In pursuit of Barry's body, which was fused with animal souls sent by the androids, Mastan led his men into the third laboratory in Central.

"Fullmetal Alchemist's realm?" Just after Mastan broke into the Makusan Research Institute, with a silent spatial fluctuation phenomenon, three figures descended into the corner of Centraar, and they were the last participants in this free adventure mission.

Barry, who took the lead in the pursuit, relied on the spiritual connection between the soul and the **, and chased his body frantically under the strong ** drive of his own. Later, after entering the underground of the research chamber by Mastan, Alphons, Habbock, and Hoké, they lost all traces of Barry. So the four of them split into two teams and searched both sides.
