"Yun Gongzi, Zi Gongzi, I came to you to ask you to help me complete a task, I don't know if you are willing?" After coming to the main hall and taking a seat, the eldest prince immediately ordered someone to pour tea for Yun Tianyu and Zilong and said.

"Mission, I don't know what task the eldest prince asked us to complete?" Yun Tianyu, who had already guessed the reason, asked softly.

"According to the information I investigated, in order to deal with my army of the Great Qian's Imperial Family, someone was mad enough to refine the Nine Yin Beads in the Nine Yin Land of the Heavenly Domain, and this Nine Yin Beads are extremely vicious things, and if they are in this life, they will be ruined, so I want to ask the two of you to go to the Land of Nine Yin to stop them from refining the Nine Yin Beads. ”

"If the two of you can stop them from refining the Nine Yin Beads, I am willing to take out two of the best immortal artifacts to repay the two of you. The eldest prince spoke in detail.

"Go to the Land of Nine Yin to stop refining the Nine Yin Beads, Great Prince, I don't know who they are in your mouth?" Yun Tianyu frowned slightly, and asked softly.

"They are a group of people who want to plot against my Daqian throne, and their strength will not be stronger than that of Zi Gongzi. Two sons, I don't know if you are willing to help me. The eldest prince looked at Yun Tianyu, who was frowning, and asked softly.

"Great Prince, don't you know that you still have Heavenly Water, if you give me another five kilograms of Heavenly Water, I will promise you. Hearing that the eldest prince didn't want to tell the person who was refining the Nine Yin Beads, Yun Tianyu didn't continue to ask, and offered additional conditions.

"Five kilograms of Heavenly Water, what do you want so much Heavenly Water for?" asked the Great Prince, who had already given Yun Tianyu three kilograms of Heavenly Water, with a shocked expression.

"I beg my pardon for keeping this secret, but the water of heaven is very important to me, if the eldest prince does not have five kilograms of water of heaven, then we will not help you. Yun Tianyu said in a resolute tone.

"Five kilograms of Heavenly Water! That's it, Heavenly Prince, if you believe me, during the time you complete your mission, I will do my best to help you exchange the Heavenly Water, and I will give you the exchanged Heavenly Water no matter whether you succeed or fail. The eldest prince pondered for a moment and said promisefully.

Although the eldest prince said it very well, but with a clear mind, Yun Tianyu caught the suspicion of the eldest prince's promise, because the mission failed in the land of nine yin, it was impossible to come back, so he could come back with a life, and nine times out of ten the task was completed.

"Okay, we've taken this task, but the Great Prince needs to send someone who is familiar with the Land of Nine Yin to follow us and help us show the way. Yun Tianyu pondered for a moment and said.

"This is no problem, I think Mr. Xu Da is with you, he is very familiar with the Land of Nine Yin, and he is a fifth-level True Immortal peak master, which is enough to deal with ordinary dangers. The eldest prince nodded, and agreed to Yun Tianyu's request very happily.

"Let's go, I'll take you to Mr. Xu Da now, you can have a good discussion with him, and then set off in two days. After speaking, the eldest prince who was secretly happy in his heart took Yun Tianyu and Zilong to the courtyard where Mr. Xu Da lived, and saw Mr. Xu Da with crane hair and childish face, like a Taoist priest.

Seeing Mr. Xu, the eldest prince immediately told him about the mission to go to the land of nine yin, and when he learned that the eldest prince had let him lead Yun Tianyu and Zilong to the land of nine yin to carry out the mission, his face immediately changed.

However, at this time, the eldest prince immediately transmitted a message to him, stabilizing Mr. Xu, who was a little flustered in his heart, so that he had to agree hard.

"Okay, the three of you should discuss it carefully, and in two days you will set off for the land of nine yin, and I will wait for your good news in the palace. After saying that, the eldest prince left.

After about an hour or so, Yun Tianyu and Zilong, who had learned a lot of valuable information, left Mr. Xu's room and returned to their room to discuss briefly.

Two days later, Yun Tianyu and the three of them left the Great Prince's Mansion and flew towards the Nine Yin Land, which was located in the western region of the Heavenly Domain.

"Heavenly Prince, Mr. Zi, the Land of Nine Yin is very dangerous, and the people who use the Land of Nine Yin to refine the Nine Yin Beads are even more evil and terrifying, so we must be extremely careful. On the way to the Land of Nine Yin, Mr. Xu, who was a little worried in his heart, said solemnly.

"Don't worry, we'll be careful. Yun Tianyu nodded lightly and said.

After about six days, Yun Tianyu and his party flew outside the Land of Nine Yin, and saw from a distance that a dark wilderness filled with a dark and damp atmosphere appeared not far ahead.

"Attention, the Yin Soul in the Land of Nine Yin has a strong summoning ability, if we encounter a Yin Spirit, remember not to leave your hand, we must kill it as soon as possible, if we accidentally let him summon a large number of companions, we will be very dangerous. Flying into the land of nine yin, Mr. Xu, who was not at ease, told again.

"Don't be verbose, we know! Zilong said impatiently.

"Woo woo!" Just as Yun Tianyu and the three of them were flying quickly in the land of Nine Yin, looking for the master who was refining the Nine Yin Beads inside, the sound of ghost crying suddenly came into the ears of the three of them.

Immediately after, five legless and gently floating in the black space, hideous-looking ghosts appeared in front of the three of them and launched an attack on the three of them.

"Huh!" The five Yin Spirits appeared, and the purple dragon body that followed behind Yun Tianyu flashed slightly, appeared in front of the five Yin Spirits, waved a powerful fist, and bombarded the five Yin Soul bodies with extremely fast speed, directly scattering them.

"It's such a terrifying attack power, it seems that he is a real sixth-level true immortal master. Seeing the power of the purple dragon's fist, Mr. Xu Da calmed down a little in his heart and meditated in his heart.

"Alright, let's move on. Yun Tianyu glanced at Mr. Xu Da, whose face changed slightly, and continued to fly towards the depths of the Nine Yin Land.

"Huhu!" Just as Yun Tianyu and the three of them were flying quickly in the land of Nine Yin, they suddenly felt that the yin qi around their bodies was gradually thickening, and a stream of yin wind slapped on their bodies, making their bodies feel a faint pain.

"Why is it suddenly dark!" Just as Yun Tianyu and the three of them were resisting the invasion of yin qi and flying quickly, the three of them felt that the sky suddenly darkened, as if a storm was about to fall.

"No, this seems to be the Nine Yin Trend in the Land of Nine Yin. Our luck was a little too bad, and we actually encountered the second most dangerous Nine Yin Tide in the Land of Nine Yin. "Mr. Xu Da, who is very familiar with the land of the Nine Yins, saw the sky that suddenly darkened, and immediately thought that this kind of vision of heaven and earth should be caused by the Nine Yin Tide.

"Nine Yin Wind Tide, I don't know if we can avoid the attack of Nine Yin Wind Tide by burrowing into the formation?" Yun Tianyu frowned slightly and asked softly.

"The Nine Yin Storm is extremely penetrating, and the danger of hiding in the Nine Yin Storm is even higher, because underground, our activities will be greatly restricted, and we can only defend with all our might. ”

"And if you want to defend against the Nine Yin Tide, it will be difficult to reach the sky, so in the face of the Nine Yin Tide, the best way is to break through with all your strength, as long as we can break through, we will be safe. Mr. Xu Da shared his experience.

"Break out with all your might, okay then. "Yun Tianyu has refined one-third of the Lost Crown, and defense is his strong point, but Mr. Xu Da keeps it useful, so Yun Tianyu still agrees with Mr. Xu Da's proposal to break through with all his might.

"Okay, let's adjust our internal breath and wait for the Nine Yin Tide to break through with all our might. After speaking, Mr. Xu Da quickly sat on the ground and adjusted his state.

Just when Yun Tianyu had breathed half a pillar of incense for three days, a series of creepy ghost cryes came into the ears of the three of them.

Hearing the sound of devil crying, Yun Tianyu and the three of them quickly opened their eyes, and saw that the black pressure of the Nine Yin Wind Tide had approached ten meters in front of them, and immediately flew into the void, like three flying arrows off the string, flying into the Nine Yin Wind Tide with a sound of breaking the air.

Flying into the Nine Yin Tide, Yun Tianyu immediately saw that the Wind Tide was full of Yin Spirits, and they rushed towards him, biting his body, and immediately defended with the help of the Lost Crown.

"Purple Gold Gourd, absorb!" When the defensive light released by the Lost Crown easily resisted the bite of the Yin Spirit, Yun Tianyu sacrificed the Purple Gold Gourd with a move of his mind, controlling the Purple Gold Gourd to release a powerful suction, frantically absorbing the Yin Soul in the Nine Yin Tide.

Although the purple gold gourd was only a medium-grade immortal weapon, the devouring power released by the purple gold gourd greatly restrained the yin souls in the wind tide, and a large number of yin spirits were absorbed by the purple gold gourd and collected into the gourd.

Yun Tianyu controlled the defense of the Lost Crown while controlling the absorption of the Purple Gold Gourd, and shuttled through the Nine Yin Tide very easily.

"Yin!" Yun Tianyu ignored the threat of the Nine Yin Tide, and the purple dragon that was attacked by a large number of Yin Spirits immediately released a powerful dragon groan and attacked the Yin Soul that attacked him.

Attacked by the terrifying dragon groan, a large number of Yin Spirits dissipated, and Zilong relied on his own strength to easily open a passage.

"The dragon's groan, how can that person surnamed Zi make a dragon's groan? Isn't he a human, he's a dragon? Mr. Xu Da, who had done his best to quickly shuttle through the Nine Yin Tide, immediately showed surprise when he heard the dragon groan emitted by the purple dragon.

However, in the Nine Yin Tide, Mr. Xu Da was not allowed to think too much, he constantly fused with the best immortal weapon sword in his hand, and forcibly broke through with the integration of human and weapon.

"Well, saturated, saturated so quickly. When Yun Tianyu controlled the purple gold gourd to devour, he found that the purple gold gourd was quickly saturated and could no longer absorb the yin soul, so he immediately put the purple gold gourd away.

Putting away the purple gold gourd, Yun Tianyu immediately summoned the wings of the Golden Peng, and after greatly increasing his speed, he flew towards the outside of the Nine Yin Wind Tide.

After about an hour or so, Yun Tianyu, who was not affected by the Yin Soul in the Nine Yin Tide, successfully passed through the Nine Yin Tide.

Not long after Yun Tianyu passed through the Nine Yin Tide, the purple dragon that turned into a purple streamer also successfully penetrated the Nine Yin Wind Tide and merged with Yun Tianyu, waiting outside for Mr. Xu Da who was trying his best to break through.
