Tianyu Island, the wind and evening forest, the white-clothed swordsman who lived in seclusion here suddenly opened his eyes, and looked up in the direction of the city, the heavenly eye that had been closed for many years on his forehead opened again, and the distance of thousands of miles was as clear as in front of him, and the white-clothed swordsman stroked the hair on the back of the white fox in his arms, and said with a little surprise in his mouth: "Xia Wei...... It is rare for the king of the dead country to have such power, but ...... The ethereal sword momentum I created to practice my mind sword intent is not easy to match!"

At the same time, in the city, Yi Yin used his fingers as a sword to make the first type of sword ethereal, and the mana turned into a light gold glazed sword qi through his fingers, and it shot through the blood wolf howl sent out by Xia Ji without hindrance, and then shot unabated on the ground in front of Xia Ji, and the sword qi spread into the ground in all directions, and the already damaged Yan zhòng's Alluring Palace was completely destroyed at this time, Xia Wei looked at Yi Yin's figure who was gradually disappearing in the distance, and had to let out an unwilling roar, but he did not continue to chase.

"What a Yi Yin, it's so deeply hidden!" Xia Jian said with a hideous face, the moment Yi Yin sent out Jian Yi, Xia Wei actually felt an extreme threat from it, and what surprised Xia Yi even more was the power of Jian Yi, he could see that Jian Yi's move was just a heaven-level martial art, and the moves performed by Xia Ji, who was reincarnated by the Demon Beast, whether it was Blood Wolf Fang, Blood wolf claws or blood wolf howls, all of them are god-level martial arts, although they are limited to cultivation and these god-level martial arts cannot exert their true power, but they are by no means heaven-level martial arts can be compared, and Xia Wei's killing of Guan Longxiao with a punch of blood wolf teeth that day is the best proof.

But Fang Cai is this only heaven-level sword, and it easily pierced through his god-level roar, I am afraid that this kind of thing is not only that the Great Wilderness has never happened, even the three thousand worlds are the only case, is it because he has been dead for too long, so that the move issued is in vain, or is there some amazing secret on this Mr. Yi Yin? Xia Wei knew that no matter what the situation, he would not be able to leave Yi Yin today, even if he was unwilling in his heart, he could only go with him.

At this time, outside the Wanglong Pavilion on Dongping Street, the defenders of the city who had already received Xia Wei's order had surrounded the most prosperous restaurant in the past in this city, and among the onlookers, the general of the unified army waved his hand, and hundreds of soldiers immediately rushed into the Wanglong Pavilion, but after a while, there was news that the Wanglong Pavilion was already empty, and the apprentice Lingxin who should have been left in the Wanglong Pavilion by Yi Yin was already missing!

In a hidden courtyard near the east gate of the city, the spiritual heart carrying the package appeared here, this place originally belonged to the secret stronghold of the Yijian Tingyu Pavilion in the city, and it was idle after the disciples of the sword completely evacuated the Great Xia Dynasty, and then it was transferred to Yiyin by the Yijian disciples who came to the city to connect with Yiyin, and became a secret stronghold unknown to Yiyin, and there is a secret passage in the Wanglong Pavilion that leads directly to this courtyard.

"Hmph, the encirclement still wants to trap me, don't you know that the secret passage is prepared for this time?" Lingxin who walked out of the secret passage said quite arrogantly, but she also knew that the secret passage could not be delayed for too long, as long as the general of the unified army had a little experience, he would think that there was a secret passage in the Wanglong Pavilion, and it was only a matter of time before the secret passage and this courtyard were exposed under the search of the soldiers, so Lingxin said with a little worry: "Master, you should come back quickly!"

"Don't worry, come for the teacher. As a rare top master in the world, Yi Yin, who left the palace, hid his body all the way, and no one could detect his existence at all, he came to the courtyard very smoothly, and it was only a moment different from the spiritual heart who came here from the secret passage from Wanglong Pavilion, but after coming to the courtyard, Yi Yin knew in his heart that this place was not a safe place, because he felt that there was a powerful aura from the secret passage and quickly approached this courtyard, and from the breath, that person should be the Demon Eye Sword Venerable！

"It's so fast!" Yi Yin said with a slight frown, and then he felt two strands appear one after another around this courtyard, and from the breath, Yi Yin sensed that these two people were the Demon Hand Swordsman and the Demon Blood Sword Maniac, Yi Yin's face suddenly changed slightly, because he immediately realized that this courtyard that he regarded as a hidden stronghold may have already been exposed, and the existence of that secret passage had already been mastered by the enemy, and only in this way could it be explained why the Demon Eye Sword Venerable would come here so quickly.

"If I say, it's not my secret...... Do you believe it?" Lingxin, who also sensed the breath of the three of the four demon swords, said innocently, Yi Yin smiled and nodded when he heard this, in fact, he did not doubt that Lingxin would go to the informant, but suspected that the disciple of Yijian Tingyu Pavilion who handed over this courtyard to him back then, his identity may not be as simple as a disciple of Yijian, he gave this courtyard to himself, it is very likely that it is Xia Wei or the Demon Eye Sword Venerable, and the latter is the most likely!

"With just one courtyard, I have set a route for my escape, Demon Eye Sword Venerable, but I, Yi Yin, underestimate you!" Yi Yin looked at the exit of the secret passage and sighed, just as he sighed at this moment, the Demon Eye Sword Venerable in the secret passage had already rushed out of the secret passage, and the Demon Hand Swordsman and the Demon Blood Sword Maniac had also come to the courtyard, and it had been completed with three measurements and two dimensions!

"Demon Eye Sword Venerable, long time no see!" Yi Yin looked at the Demon Eye Sword Venerable and smiled lightly, it was also very interesting to say, although the Demon Eye Sword Venerable was the one who brought him back to the city, but since Yi Yin was his chef in Wanglong Pavilion, he hadn't seen the Demon Eye Sword Venerable again, so it had been thirteen years, but now he was blocked in this courtyard by the three of the Demon Eye Sword Venerable, but he didn't have the slightest fear, because he knew that the Demon Eye Sword Venerable couldn't stop him!

"Eldest sister, long time no see!" The Demon Eye Sword Venerable, who walked out of the secret passage, did not respond to Yi Yin's words for the first time, but turned his head to Lingxin and said, as we all know, as the second of the four demon generals, there is only one person who can be called the eldest sister by him, and that is the Demon Heart Sword Spirit, the head of the Four Demon Swords, who has not appeared for many years, and at this time he is actually called Lingxin Eldest Sister, doesn't that mean that Lingxin is the Demon Heart Sword Spirit!

"Long time no see, second brother!" Lingxin also nodded when she heard the words and said, her two greetings with the Demon Eye Sword Venerable immediately confirmed her identity, if the identity of the Lingxin is really the Demon Heart Sword Spirit, then we will suddenly find that the matter of Yi Yin saving the Lingxin back then was itself a big deception, as a master of the realm of refining the Void and the Dao, how could the Demon Heart Sword Spirit be chased by a few big men, that from beginning to end, it was a drama set up by the Demon Eye Sword Venerable and the Demon Heart Sword Spirit, the purpose was obvious, that is, to let the Spirit Heart mix into the caravan of Yi Yin and his party, so as to go undercover by Yi Yin's side！

But what is surprising is that Yi Yin did not have the slightest surprise on his face, as if he already knew the identity of Lingxin, in fact, it was exactly the case, when Yi Yin unusually saved Lingxin, which also caused Zhong Yu's surprise, it was because Yi Yin found the abnormality on Lingxin's body, but at that time, Yi Yin did not associate her with the Demon Heart Sword Spirit, but only saved her with an observational mentality, until they returned to the Yin Shang tribe, Yi Yin did not have this idea, until the mission led by the Demon Eye Sword Venerable arrived, Yi Yin had a rough guess about the identity of Lingxin。

As we all know, the Four Demon Swords have always been inseparable, at least thirteen years ago, but at that time, there were only three of the Four Demon Swords in the mission, and only one of the Demon Heart Sword Spirit was missing, and then the Demon Heart Sword Spirit's cloak and masked outfit, as well as the very strange appearance of the Four Demon Swords from young to old, as well as the unusual appearance of the Spirit Heart, Yi Yin, who connected these together, suddenly had a bold assumption, whether the appearance of the Demon Heart Sword Spirit was likely to be younger than the Demon Eye Sword Venerable of the young man, and the Demon Heart Sword Spirit did not necessarily have to be a man, she might be...... A little girl!

As the wise man of the world, Yi Yin is not the kind of person who will be immediately sure if he has a little guess, he naturally wants to find someone to verify what he thinks, and this person is best to be the Demon Eye Sword Venerable who is the same as the Demon Heart Sword Spirit of the Four Demon Swords, so when the Demon Eye Sword Venerable in the council hall of the day was in trouble, Yi Yin suddenly told him that he was the master of the Spirit Heart, and Yi Yin did not know the name of the little girl at that time, and the name of the Spirit Heart was to put it bluntly to take out the words heart and spirit from the title of the Demon Heart Sword Spirit, and then reverse the order, and he said this not only to verify the identity of the Spirit Heart, the deeper reasons we will talk about later, and hearing who the spirit heart in Yi Yin's mouth was, the Demon Eye Sword Venerable chose to avoid it temporarily, which also made Yi Yin believe that his guess was not wrong, so Yi Yin simply took advantage of the situation and really included the spirit heart under the door, so that Yi Yin turned into an elder of the four demon swords, which made the Demon Eye Sword Venerable depressed for a while, and got back to business!

"Demon Eye Sword Venerable, you...... Which side are you on?" Yi Yin looked at the Demon Eye Sword Venerable and asked, this is also the question he has been pressing in his heart, the Demon Eye Sword Venerable is a wise man, but his actions have some snakes and rats, on the one hand, he is Xia Wei's right-hand man, but on the other hand, he has obviously released water many times, although Yi Yin knows the reason for this, he still wants to determine what the Demon Eye Sword Venerable thinks, but after listening to the Demon Eye Sword Venerable, he was silent for a while and replied, "I...... Just on my side!"

"Yes......" Yi Yin said unexpectedly when he heard this, he had already been mentally prepared for the answer of the Demon Eye Sword Venerable, so he stared at the Demon Eye Sword Venerable, and asked his last question: "So...... Are you here to stop us from leaving?"
