"Tian Yu, I have just recovered to the first-level Golden Immortal Realm now, and you have already broken through to the seventh-level Golden Immortal Realm, so the time you and I have stayed in this fifth-layer space is different, I suggest that we go our separate ways and find the source of energy in this fifth-layer space. And if you break through to the realm of Xuan Immortals, don't wait for me, just go directly to the sixth layer of space to cultivate, and then we will directly use the communication bead to contact. Entering the fifth layer of the Heavenly Tomb, Nalan Xuan glanced around at the empty environment around him and proposed softly.

"Okay, Xuan'er, be careful, if I break through to the realm of Xuan Immortal and go to the sixth layer of the Heavenly Tomb, I will tell you with the teleportation bead. Yun Tianyu nodded lightly and said.

"Brother Tianyu, you should be careful. Nalan Xuan walked lightly in front of Yun Tianyu, stood on tiptoe and kissed his cheek lightly, and said softly.

After Yun Tianyu kissed goodbye, Yun Tianyu summoned the wings of the Golden Peng, flapped quickly, and flew towards the fifth layer of the Heavenly Tomb at an extremely fast speed.

As Yun Tianyu reached the seventh-level Golden Immortal realm, the wings of Jinpeng connected to his bloodline also transformed, flying faster, and in the blink of an eye, Yun Tianyu flew out thousands of meters, releasing a powerful soul power to search for the power contained in the fifth layer of space.

"Well, the desert, it's a big desert. When Yun Tianyu quickly flapped his wings and flew, he found that a large area of golden desert appeared in front of him, and when the sunlight reflected by the strange sun in the sky sprinkled on the desert, it immediately reflected a dazzling light.

"It seems that the power contained in this fifth layer of space is hidden in this desert. When Yun Tianyu flew into the desert that emitted scorching energy, he immediately felt the powerful power of the desert, and silently recited it in his heart.

"Well, there's something down in the desert. Just as Yun Tianyu lowered his flight altitude and flew close to the golden desert, searching for the lifeforms in the desert, he suddenly sensed that there was a movement of lifeforms in a desert not far ahead, and immediately accelerated and flew over.

"True Dragon Groan!" Flying above the desert, Yun Tianyu immediately released a deafening dragon groan, penetrating into the desert, directly shaking out a black scorpion hidden in the desert.

"Hiss!" was shocked by Yun Tianyu's release of the dragon's groan, the body length reached three meters, the whole body was pitch black, and the black scorpion with a long poisonous tail danced a pair of huge black pincers, and let out an angry roar at Yun Tianyu.

"The black scorpion of the fifth-level Golden Immortal Realm!" Feeling the strength of the black scorpion in front of him, Yun Tianyu's heart moved, and he sacrificed the Nine Spear of the True Spirit Sacred Weapon, and launched an attack on it with an acceleration.

Yun Tianyu landed with the September spear in his hand, and the black scorpion immediately danced the black pincers to meet it, and when the September spear in Yun Tianyu's hand collided with the black pincers, there was immediately a violent collision sound.

"Crack!" Regretting the black pincers that danced with the black scorpion, Yun Tianyu immediately controlled the immortal qi origin particles to melt into the September spear, stimulating the attack power of the September spear and forcibly cracking its black pincers.

The black pincers were shattered by the powerful force of the September spear, and the black scorpion immediately flicked its long scorpion tail and stabbed at Yun Tianyu.

"Broken!" The poisonous tail containing the poison was drawn, Yun Tianyu's body suddenly accelerated, and appeared next to the black scorpion poisonous tail, holding the September spear and whipped heavily at the junction between the poisonous tail and the body, directly cutting off its poisonous tail, and a large amount of blood flowed out along with the venom.

"Die!" Pulling off the tail of the black scorpion, Yun Tianyu's entire body fused with the September spear, and the human weapon was inserted into the head of the black scorpion, directly piercing the head of the black scorpion and killing it.

After killing the black scorpion, Yun Tianyu immediately dug up the black scorpion's beast pill and found that the black scorpion's beast pill was very peculiar, it was a pure energy crystal nucleus.

"Absorb!" Scooping up the Beast Pill, Yun Tianyu immediately operated the Origin Space-Time Technique, controlled the Immortal Qi Origin Particles in his body to devour the Beast Pill, and quickly absorbed the Black Scorpion Beast Pill.

After absorbing the black scorpion method, the immortal qi origin particles in Yun Tianyu's body split again, but because the black scorpion only had the strength of a fifth-level golden immortal, Yun Tianyu devoured its beast pill power and did not increase much strength.

"It seems that if I want to break through to the seventh-level Golden Immortal as soon as possible and reach the first-level Xuan Immortal realm, I must find an immortal beast of the seventh-level Golden Immortal realm to kill. Feeling that the energy crystal nucleus of the fifth-level Golden Immortal Realm had limited improvement in his strength, Yun Tianyu decided to only look for the immortal beasts of the seventh-level Golden Immortal Realm to kill.

After deciding, Yun Tianyu continued to fly in the vast and boundless desert, searching for the immortal beasts of the seventh-level Golden Immortal Realm hidden in the desert.

Just as Yun Tianyu was searching for immortal beasts, Nalan Xuan, who possessed the soul of the immortal monarch realm, quickly locked on several powerful immortal beasts that were extremely hidden and used soul skills to kill.

When Nalan Xuan devoured several precious energy crystal nuclei in a row, her strength continued to improve, and she soon broke through from a first-level golden immortal to a fourth-level golden immortal realm.

Although the realm improved quickly, Nalan Xuan was not satisfied, and Miaoman's body directly drilled into the golden desert, directly searching for hidden immortal beasts in the desert.

"Bang! It's another fifth-level Golden Immortal Realm immortal beast?How could there be so few seventh-level immortal beasts in this golden desert?" Yun Tianyu searched for about three days, but he didn't find the existence of a seventh-level immortal beast, so he had to continue to kill low-level Golden Immortal Beasts.

However, although the low-level immortal beasts were easy to find and kill, their beast pills had limited effect on Yun Tianyu, and gradually, Yun Tianyu lost his patience, pondered for a while, and gave up searching for the seventh-level immortal beasts, but looked for the entrance to the sixth layer of space.

Yun Tianyu lost his patience because he couldn't search for a seventh-level immortal beast, and returned to the fifth-level Golden Immortal realm, and Nalan Xuan, whose realm breakthrough speed had slowed down, gradually lost his patience and decided to leave here and go directly to the sixth layer of the Heavenly Tomb.

However, the space of the Heavenly Tomb was extremely vast, and it was not easy to find the entrance to the sixth layer of space, Yun Tianyu and Nalan Xuan patiently searched for about four days, but they did not find the entrance to the space.

"Don't you know where the entrances to each floor of the Heavenly Tomb are in the Heavenly Key?" Just when Yun Tianyu couldn't find the location of the entrance to the Heavenly Tomb, he suddenly thought of the Heavenly Key.

When Yun Tianyu unleashed a powerful soul power to infiltrate the Heavenly Key that was full of powerful forbidden power, he really found the general topographic map of the various layers of the Heavenly Tomb in the Heavenly Key.

"It turns out that this Heavenly Tomb has a total of eleven layers, and the power of the immortal realm should be in those eleven layers of space. "Successfully obtained the general topographic map of each layer of the Heavenly Tomb, Yun Tianyu immediately told Nalan Xuan the information and terrain of each layer through the communication bead.

Then, he roughly determined his orientation and flew towards the entrance to the sixth layer of space at great speed.

After about half a day or so, Yun Tianyu, who had been identified all the way, successfully flew to the entrance to the sixth layer of space, and found the guardian entrance, and his whole body looked like a guardian composed of sand.

"Well, the strength of this guardian surpasses that of a seventh-level golden immortal, how can this be?" Feeling that the aura of the sand guardian in front of him far surpassed his own, Yun Tianyu was slightly surprised.

However, although the difference in strength between the seventh-level Golden Immortal and the first-level Xuan Immortal was large, the hole cards that Yun Tianyu had were even more terrifying, Yun Tianyu sacrificed the September Spear, and his entire body suddenly accelerated, launching an attack on the Sand Guardian.

Yun Tianyu stabbed with the September spear in his hand, and a large number of swirling sand nests immediately appeared in front of the Sand Guardian, directly swallowing Yun Tianyu inside.

"Lost Crown, Defense!" was swallowed by the swirling sand nest, Yun Tianyu immediately controlled the Lost Crown for defense, and the sound of dense sand grinding continued to reach his ears.

"September spear, September piercing the sky!" After using the defense power of the Lost Crown to fill the swirling sand nest, Yun Tianyu immediately controlled the September spear and stabbed at the Sand Guardian.

At the moment when Yun Tianyu stabbed the Sand Guardian's body, the Sand Guardian's body suddenly exploded, and a powerful self-explosion force bombarded the Sand Guardian's body that was unable to react, directly shocking him out.

Although Yun Tianyu had the Lost Crown to defend, he was still injured by the sudden self-detonation force, and wisps of blood flowed from the corners of his mouth.

The self-detonation body shook Yun Tianyu, and a cloud of yellow sand quickly squirmed in front of Yun Tianyu, and soon condensed into a sand guardian.

"The guardian who leads to the sixth layer of space is indeed a little difficult. Yun Tianyu gently wiped away the blood that overflowed from the corner of his mouth, put away the Nine Spear of the True Spirit Hallows, and sacrificed the best space-time key in the Heavenly Hallows, which he had been refining.

The moment Yun Tianyu activated the key of time and space, the time flow velocity around Yun Tianyu's body immediately changed, and a large amount of space folded and overlapped.

And the sand guardian with wisdom sensed the horror of Yun Tianyu's sacrifice of the key to time and space, and did not take the initiative to attack Yun Tianyu, looking at him vigilantly.

"The key of time and space, the power of time and space, strangle!" When all the immortal qi origin particles in Yun Tianyu's body were injected into the key of time and space, the key of time and space immediately reflected the power of time and space in a folded space, like a meteor that fell to the mortal world, bombarding the body of the sand guardian who was affected by the power of space and was slow to act, and with a "bang" sound, the sand guardian was attacked by the key of time and space forcibly controlled by Yun Tianyu, and the entire body immediately exploded, and the breath of life in the body disappeared completely.

"Huhu!" However, although Yun Tianyu controlled the key of time and space to kill the sand guardian in seconds, because his realm was limited and he only refined one ten-thousandth of the key of time and space, it was extremely expensive to use the key of time and space to attack.

At this time, Nalan Xuan flew over at an extremely fast speed through the topographic map told by Yun Tianyu.

"Tianyu, what's wrong with you!" Nalan Xuan appeared, feeling that Yun Tianyu was very weak, and immediately asked with concern.

"I'm fine, I used the key of time and space to attack just now, and the consumption is a bit large, just take a break. Yun Tianyu, whose face was pale, shook his head lightly and said.

"Tianyu, I'll give you the Dharma protector, and when you are fully recovered, we will enter the sixth layer of the Heavenly Tomb together. Nalan Xuan urged with concern.

"Okay!" Yun Tianyu nodded, and immediately sat cross-legged on the ground, running the Origin Space-Time Technique to recover quickly.
