The World Tree was unattainable, Xia Mu didn't know how long they had been flying, and when they arrived at the canopy of the World Tree, they were as calm as Xia Mu, and they couldn't help but breathe a sigh of relief.

Fortunately, this World Tree has not fully grown, otherwise with the size of an adult World Tree, that height is comparable to a world, and I am afraid that it will not be able to fly without three or four days of effort.

Unlike the near-complete Sishen Hall, the Yinhai Hall, which sits in the canopy of the World Tree, is dilapidated, and all you can see is a ruined wall, and there is no complete palace.

"The Lord of Yinhai, even among the Palace Masters of the Six Palaces, his strength is enough to rank in the top three, it seems that in the battle of the Immortal Gu back then, he was also hit by the key blows of the overseas evil clans. ”

The Xuanyin Fairy looked at the ruins in front of him and couldn't help but let out a sigh, but he quickly cleaned up his mood, and slowly pressed his palm on the torso of the huge World Tree under the feet of the three of them.

Bang bang bang!

In an instant, with the Xuanyin Fairy as the center, the mana fluctuations visible to the naked eye spread, causing the canopy of this world tree to tremble, and then the ruins of this area, those ruins that had not collapsed, among which the decaying ones began to collapse one after another.

In the blink of an eye, the ruins in front of the three of them were empty, and a crater as large as a small basin was revealed.

In the center of this huge crater, there was a cyan dragon made of countless rattan weaving, and Xia Mu could sense that there was a very large vitality in its body, which was in stark contrast to the dead qi of the World Tree.

It was quietly entrenched in the pit, as if it was a living thing, staring fiercely at Xia Mu and his party.

Seeing this "green dragon", Xia Mu obviously felt that the Xuanyin Fairy breathed a sigh of relief, and couldn't help but ask: "Senior, is this green dragon a token of Yinhai Palace?"

"Yes, the Yinhai Palace Token is a wood-based treasure bred by the World Tree, so it has the ability to transform into shapes. The Xuanyin Fairy looked at the green dragon entrenched in the middle of the pit and explained with a smile.

The token of the Lord of Yinhai is still there, which means that the people of the Spirit Sword Palace and the Heavenly Snake Demon Temple have not yet succeeded.

"Your Highness, I thought it was strange before, why didn't the overseas evil clan destroy the Liuhe Palace when they invaded the Beginningless Immortal King Palace?" The Red Ghost Venerable on the side asked the question that Xia Mu had always wanted to ask but didn't ask.

In the battle of the Immortal Gu, even the immortal king-level powerhouses fell, but the tokens of the Shenhe Palace and the Yinhai Palace were actually well preserved, and the reasons for it were obviously not as simple as they seemed on the surface, as for the other four palace tokens, if there was no accident, they should have been preserved intact.

"I don't know, maybe those overseas evil clans don't care about this. ”

The Xuanyin Fairy said lightly, but Xia Mu obviously saw that his eyes flickered, and he felt a little insincere.

"Okay, time is pressing, you guys are waiting here, I'll go collect the token of Yinhai Palace. The Xuanyin Fairy didn't seem to be too lazy to dwell on this issue, and after saying a casual word, he took the Beginningless Immortal King Order on Xia Mu's waist into his hand with a palm move, and then began to read the words.

Xia Mu tried hard to hear the immortal recipe recited by the Xuanyin Fairy, but he was never able to hear it clearly, and finally had to give up.

Airplanes!

It didn't take long for the Beginningless Immortal King Ling, who was held in the hand of the Xuanyin Fairy, suddenly burst into a golden light, dazzling, so that the world seemed to be dyed with a layer of gold, and then only a golden light rushed out from the token, piercing the void with a bang, and appeared above the green dragon.

Roar!

A trace of fear flashed in the eyes of the green dragon entrenched in the center of the pit, but it still let out a low roar unwillingly, and at the same time opened its mouth and spewed out a large cyan blade, cutting through the space and slashing towards the golden light.

However, in the face of the attack of these cyan blades, the golden light ignored it, and fell towards the green dragon with a patch of cyan blades.

When the two came into contact, a surprising scene appeared, the golden light actually merged into those cyan blades, and in the blink of an eye, all the blades turned into a piece of gold, and then they swirled around in the void for a week, slashing towards the green dragon.

Seeing this, Xia Mu and the Red Ghost Venerable were both taken aback, that golden light was so powerful that it could turn the opponent's attack into their own use.

Whew!Whew!

The pieces of golden blades were like piranhas that smelled blood, and they slashed at the body of the green dragon when it was caught off guard, and at this time, the golden light on the blade seemed to come to life again, detached from the blade, and submerged into the body of the green dragon.

Then the green dragon screamed, and in the blink of an eye, its huge body began to shrink, and finally turned into a cyan seed.

"This is the essence of the Yinhai Hegong token?" Looking at the seed, Xia Mu couldn't help but ask.

"This is the seed of the World Tree, and a World Tree can only give birth to one such seed in its lifetime. Xuanyin Fairy said: "The reason why the World Tree is almost extinct is also because of their way of gestation, once the tree species is destroyed, then the same World Tree will not be able to give birth to a second one. ”

The Red Ghost Venerable said curiously: "My subordinates have heard that when the Lord of Yinhai attacked the Immortal King Fruit Position, he failed several times, and it was by relying on the World Tree's continuous supply of life essence that he finally became the Immortal King, but because of this, the World Tree stopped growing and did not fully grow. ”

"That's right, otherwise, when this World Tree grows, it is also comparable to an immortal king-level existence, and every drink and peck in this is the destiny of the Heavenly Dao. Fairy Xuanyin said lightly: "The sacrifice of the World Tree has achieved the Lord of Yinhai, but the balance between loss and gain is not something we can put on our beaks." ”

Hearing this, Xia Mu sneered in his heart, saying that the good thing is sacrifice, and the bad thing is to take the fruit of humanity, if there is no Lord of Yinhai, this world tree will grow up, and it will inevitably be an immortal king-level existence.

However, if it were Xia Mu himself, he would not have chosen this way, after all, once he set foot on this road, he would not be able to turn back, just like sailing against the current, if he does not advance, he will retreat.

After the Xuanyin Fairy knocked the green dragon back to its original form, with a move of her palm, she wanted to take the World Tree seed into her hand.

However, at this moment, a jade hand silently reached out from the space not far away, directly holding the World Tree Seed in his hand in front of everyone's eyes.

At the same time, a figure with a devilish figure also emerged from the space.

"The praying mantis catches the cicada and the yellow finch is behind, it seems that this Yinhai Palace token should fall into my hands. At the moment when the jade hand held the World Tree seed, a natural enchanting voice sounded.
