"This is the entrance to the Heavenly Tomb!" Sensing the vision behind him, Yun Tianyu immediately turned around and found that a strange sealing space appeared behind him, and immediately guessed that this sealing space was likely to be the entrance to the Heavenly Tomb.

And the reason why the entrance to the Tomb of Heaven appeared here is probably because it sensed the Key of Heaven.

In order to check the reality of the entrance to the mysterious space in front of him, Yun Tianyu took the key of heaven from the three-tailed fox and inserted it into the seal prohibition on the surface of the mysterious space.

When the key of heaven touched the forbidden space of the mysterious space, a majestic force suddenly surged out of the mysterious space, directly shaking the ghost snake and the three-tailed fox around Yun Tianyu's body, and poured into the body of Yun Tianyu who couldn't move, instantly stretching his body open, and a huge pain instantly spread throughout his body.

"How can this be, am I going to be blown up and die!" Feeling that his body was about to be blown up, Yun Tianyu felt a trace of panic in his heart, desperately controlling the weather origin particles to absorb the powerful energy that poured into his body.

Although the speed at which the Weather Origin Particles devoured was fast, it could not be compared to the speed at which the energy gushing out of the mysterious space.

Seeing that Yun Tianyu's body was about to be stretched out by the energy that was released into him, the space-time dream in Yun Tianyu's mind suddenly became agitated, releasing a strange energy that instantly flowed throughout his whole body, suppressing the terrifying energy that poured into his body.

And just when the space-time dream was restless, releasing the power to help Yun Tianyu suppress the energy, the mysterious space immediately became restless, as if someone was crazy about impacting the space prohibition and wanted to break free.

With the suppression of the space-time dream, Yun Tianyu passed the dangerous period for a short time, and the weather origin particles in his body that were frantically devouring energy continued to reach saturation and split new particles.

"Master, there are quite a few masters approaching your side!" Just when Yun Tianyu, whose body couldn't move, continued to control the devouring of the weather origin particles, the Nether Snake and the Three-Tailed Fox, who had just been shocked by the energy released by the mysterious space, sensed the danger and immediately transmitted the voice to tell Yun Tianyu.

"There are quite a few masters approaching!" Yun Tianyu, who couldn't dispel the spatial suppression, was distressed when he heard the news, and repeatedly impacted the suppression space several times without any effect, and finally gave up helplessly.

Just when Yun Tianyu couldn't leave, four blurred lights and shadows appeared, and when the four of them saw Yun Tianyu at the entrance of the mysterious space, the key to the sky inserted in the entrance of the mysterious space, they all showed greed.

"Well, isn't that the Key of Heaven? When an old man in a snow-white robe with crane hair and a childish face saw the Key of Heaven, he immediately recognized the reality of the Key of Heaven and became excited.

"The Key of Heaven, the only key that can open the Tomb of Heaven is said to be. Haha, we finally have the courage to get married. Another middle-aged man in a dark blue robe, with a hooked nose and eyes sunken into his cheeks, couldn't help but get excited when he learned that what was in front of him was the key to heaven.

"Kill that person first!" The shortest and bloated middle-aged man among the four squinted his eyes, glanced at Yun Tianyu coldly, and said ferociously.

Just as the four of them were about to attack, they sensed that Yun Tianyu was in danger, and the Nether Snake and the Three-Tailed Fox appeared together and launched an attack on the four of them.

"Hmph!" The ghost snake and the three-tailed fox attacked, and the middle-aged man with a bloated body snorted coldly, suddenly opened his mouth, and spit out two rays of true immortal light, hitting the two major immortal beasts, directly hitting them.

"Fourth-level True Immortal!" Yun Tianyu, who couldn't move, saw that the Nether Snake and the Three-Tailed Fox were shot away without any ability to resist, and were hit hard, and immediately guessed that the bloated man was a fourth-level True Immortal.

"Boy, give me death!" The bloated man knocked the Nether Snake and the Three-Tailed Fox away, and the crane-haired and child-faced old man immediately struck, unleashing a powerful True Immortal Rule power to kill Yun Tianyu, who couldn't move.

However, when the True Immortal Rule, which was enough to kill the third-level True Immortal Master, hit Yun Tianyu, it did not break through the mysterious power that suppressed him, and the True Immortal Rule power trembled slightly, and it completely dissipated.

"What, what kind of power is that, it can actually resist the power of the True Immortal Rules I released. The crane-haired and child-faced old man realized the power of the mysterious power around Yun Tianyu's body, revealing a deep look of surprise.

"Let's all attack together, work together to kill him, and take the Key of Heaven. The only silver-haired woman of the four suggested in a low voice.

"Okay, let's attack together!" Thinking of the legend in the Heavenly Tomb, the three of them nodded in agreement, and together they attacked Yun Tianyu, who was suppressed by death.

When the four True Immortal Rule forces that distorted the space bombarded Yun Tianyu, just like just now, after trembling slightly, it immediately dissipated, and it was unable to harm Yun Tianyu at all.

"How can this be, what is the power around that kid's body? With the strength of the four of us at the fourth level True Immortal Realm, we can't even break it. The joint attack of the four people failed, which made the faces of the four people extremely ugly, and they could not accept this fact.

And Yun Tianyu realized the forbidden power to suppress himself, breathed a long sigh of relief, and quickly transmitted the message to the Nether Snake and the Three-Tailed Fox, telling them to quickly leave the retreat, and leave themselves alone.

After the Nether Snake and the Three-Tailed Fox left, Yun Tianyu slowly closed his eyes, and with the help of being suppressed by the space-time dream, he controlled the weather origin particles and continued to devour.

"Damn, I don't believe in evil, everyone is attacking with all their might, I don't believe that under our onslaught, we can't kill that kid. The bloated man with a blue face cursed, sacrificed a pair of powerful copper hammers, and continued to attack and suppress the prohibition of Yun Tianyu's body with three companions of the fourth-level True Immortal Realm.

However, although the attack of the four people was terrifying, the mysterious prohibition gushing out of the mysterious space was even more powerful, and the four of them spared no effort to storm for a whole day, but they failed to twist the prohibition around Yun Tianyu's body.

Unable to attack hard, the four of them did not give up and continued to attack, and the weather origin particles in Yun Tianyu's body were devoured and split after a day, and the number of weather origin particles in his body reached two thousand four hundred, reaching the limit of the realm.

The number of Weather Origin Particles reached the limit of the realm, and when he sensed the abnormal induction, a new strange power suddenly flowed out from the restless space-time dream, which instantly flowed all over Yun Tianyu's body.

Immediately afterwards, a large amount of thunder appeared in Yun Tianyu's body, frantically refining his body, helping him hit the bottleneck of the second-level Dao Immortal Realm.

"Thunder power, the space-time dream can actually produce quenching thunder power in my body, why doesn't the space-time dream realm have this magical ability? Could it be that because I broke through to the first-level true immortal realm, the space-time dream has changed qualitatively, but it shouldn't be, if the space-time dream realm undergoes a qualitative change, I should feel it." The body was constantly tempered by thunder power, and Yun Tianyu, who had hit the bottleneck of the realm, silently thought in his heart.

"Well, Lei Guang, how can there be thunder light in his body? Could it be that absorbing the power in the Heavenly Tomb can generate refining thunder power on his own, and quench his body to impact the realm!" The four true immortal masters who were frantically attacking the prohibition found that a large amount of thunder power suddenly gushed out of Yun Tianyu's body, revealing an incredible look.

Discovering this situation, they strengthened the determination of the four true immortal masters to kill Yun Tianyu and win the key to heaven, and the four of them continued to burst out the power of the true immortal rules and continued to attack the prohibition.

However, although the attacks of the four true immortal masters were terrifying, the prohibitions around Yun Tianyu's body did not move at all, and they were not affected at all.

"Level 2 True Immortal Realm, break through!" When Yun Tianyu's body endured a day of thunder power refining, the bottleneck of his realm was loosened, and Yun Tianyu seized this opportunity to control two thousand four hundred Weather Origin Particles to break through the bottleneck in one fell swoop and reach the Level 2 True Immortal Realm.

Yun Tianyu's own strength reached the second-level True Immortal realm, and a large amount of soul power poured out of the restless space-time dream realm, which melted into his soul, forcibly raising his soul to the second-level True Immortal realm.

The breakthrough of strength and soul did not affect the Heavenly Tomb through the Heavenly Key to continue to pour majestic power into Yun Tianyu's body.

The realm broke through, and the weather origin particles in Yun Tianyu's body recovered the devouring energy, and continued to devour the energy that poured into Yun Tianyu's body, and was suppressed by the space-time dream, accelerating the saturation split.

In this way, Yun Tianyu's unscathed cultivation, the attack of the four true immortals spared no effort, time passed minute by minute, and soon, half a month passed.

In the past half a month, many True Immortal Masters felt the breath of the entrance of the Heavenly Tomb and rushed to it.

However, in order to keep the Key of Heaven for themselves, as soon as these True Immortal Masters appeared, they were killed by four murderous Fourth-level True Immortal Masters, and a large amount of blood stained the damp ground red, and a thick smell of blood filled the space.

Since the four fourth-level True Immortals were too ferocious, they completely deterred the rest of the True Immortal Masters, and gradually, no one dared to approach the entrance of the Heavenly Tomb.

However, although the four fourth-level True Immortal masters shocked the rest of the True Immortal masters in a short period of time, as time went on, the four people who had been attacking for a long time without success gradually became anxious, and they were afraid that the appearance of the entrance to the Heavenly Tomb would attract fifth-level True Immortal masters.

Just as the four true immortal masters continued to attack without giving up, the Weather Origin Particles in Yun Tianyu's body devoured enough majestic energy and continued to accelerate the splitting, and the number of Weather Origin Particles continued to increase from two thousand four hundred, and soon reached three thousand.

"The number of Weather Origin Particles has reached three thousand, and if I increase the number of Weather Origin Particles by two hundred, I will be able to impact the Level 3 True Immortal Realm. Yun Tianyu silently recited in his heart excitedly.

"Hum!" Just as Yun Tianyu suppressed the excitement in his heart and cultivated the Origin Space-Time Technique at high speed, the Heavenly Tomb trembled violently, and then, a force that changed the color of the heavens and the earth poured out in the Heavenly Tomb and injected into Yun Tianyu's body, stretching his body open again, and a large amount of blood flowed out through the small cracks on the surface of his body.
