If I had known I wouldn't have saved you!

Endless spiritual energy gathered around him, forming a huge vortex. It was so powerful that it completely blocked out the raging strong winds in the starry sky.

As if touched by his power, many gray clouds appeared out of thin air around him, with rumbling thunder and lightning inside.

Lin Shiyi frowned and looked at him, but was not too worried.

After the Nascent Soul stage, if one wants to advance further in cultivation, one must undergo the process of tempering the body with heavenly thunder, cleansing the tendons and strengthening the body, and only after passing through the thunder of catastrophe can one completely leave the ranks of earthly immortals and become a celestial immortal.

Those dark clouds were clearly thunderclouds that were coming to help him become an immortal.

After understanding this, he continued to improve his own spiritual energy and attract the thunderclouds closer.

As more and more thunderclouds appeared, the rumbling sound of thunder resounded among the starry sky. The surroundings were filled with lightning as dense as a spider web. Under this terrifying momentum, even though Lin Shiyi was knowledgeable, he couldn't help but feel a little scared.

Soon, the calamity clouds completely enveloped him, thunder rumbled from all directions at the same time, and dazzling lightning came towards him, wrapping around his protective spiritual shield.

Lin Shiyi suddenly felt his whole body sore and numb, his spiritual energy began to be greatly consumed, and a feeling of despair arose spontaneously.

“Could it be that this is not a thunder cloud, but a treasure of a Divine Transformation cultivator, coming to kill me?”

As soon as this thought came to his mind, Lin Shiyi was immediately frightened.

As if sensing his fear, the lightning became even stronger, and with its rumbling sound, it seemed as if it would tear the entire starry sky apart.

Lin Shiyi tried his best to calm down and resist the thunder and lightning with all his strength, but his spiritual energy was consumed very quickly. If he dared to relax even a little, he would die under the rolling thunder.

Just when he was at his wit's end, he felt his body slowly changing.

After the lightning bolts wrapped around his protective aura shield, they penetrated into it bit by bit, poured into his body, and wandered through his internal organs and various veins. As the lightning bolts passed through his body, his internal organs gradually vaporized and turned into illusory existences.

Lin Shiyi was frightened at first, thinking that his internal organs were damaged by the lightning, but he did not feel any discomfort, and his body felt inexplicably lighter, so he felt relieved and no longer maintained the spiritual energy shield completely. Instead, he let the lightning in little by little to help him cleanse his muscles and strengthen his body.

This is an extremely dangerous process. One must be extremely careful to let the thunder enter the body. One cannot be impatient at all. If one fails to control oneself and is suddenly entangled by a large amount of thunder, one will probably turn into ashes on the spot and even gods cannot save one.

Lin Shiyi had great skills, so his temperament was naturally good. He was not in a hurry at all. He followed the steps and let the thunder penetrate his body, changing his body bit by bit.

No one knows how this calamity thundercloud was produced. It is obviously extremely powerful and can easily destroy a world, but it can also help cultivators to strengthen their bodies and reach a higher level.

Lin Shiyi could only sigh that the laws of heaven and earth were so mysterious.

But as time passed silently, he couldn't help but frown slightly.

The thunder had almost changed his body, but the dark clouds around him kept gathering more and more, as if there was no end. As the dark clouds gathered, the thunder and lightning in them became more powerful.

Lin Shiyi's ears were ringing due to the thunder, and his internal organs were completely destroyed. Not only that, the Nascent Soul in his abdomen also turned into a ball of brilliant golden light, emitting dazzling light. As the golden light filled his limbs and bones, a sense of power he had never felt before rose from his heart.

"This is... the state of transformation into a spirit?"

Lin Shiyi clenched his fists, feeling the benefits brought by the golden light, and couldn't help feeling extremely excited.

From then on, he no longer used spiritual energy, but another kind of extremely powerful aura. He was not sure what this aura was for the time being, but he could feel that this new power was many times stronger than the original spiritual energy.

But before he could be happy, the thunderclouds continued to gather around him. Even though he protected himself with the protective shield of a Divine Transformation cultivator, he still could not stop the invasion of the thunderclouds. Before he knew it, he was tightly wrapped up by the thunderclouds and he didn't even have a chance to escape.

"No way...Is a cultivator who has just been promoted to the Divine Transformation Realm going to die here?"

Lin Shiyi was extremely depressed and could only fight desperately to resist those thunderclouds. However, in front of the power formed by the laws of heaven and earth, even if he was a Divine Transformation cultivator, he was no match at all.

This thundercloud is tailor-made for cultivators who are going through the tribulation. Its power is determined by your strength, and you will not be able to let your guard down.

Soon, in order to resist the thunderclouds, the golden light in Lin Shiyi's body was exhausted. He looked at the rolling thunder around him in despair, his heart filled with unwillingness.

We have finally come this far and everyone has placed their hopes on him. Is this going to stop now?

If he died at this point, with no one to control the Totian Instrument, it would be unknown where the Demon Spirit Realm would float to. It might even be destroyed directly after colliding with other realms.

Thinking of the companions who had been through thick and thin with him, Lin Shiyi felt anxious.

But the facts did not allow him to think too much. Without the resistance of the golden light, the terrifying thundercloud came towards him and directly wrapped him up.

The expected explosion did not sound. Just as the thunderclouds were about to touch his body, they changed direction and rushed towards the glittering stars around them. However, after entering the stars, they did not cause the slightest ripples. Instead, they were all absorbed inside, which surprised Lin Shiyi extremely.

What on earth are these glowing stars? On the surface, it looks like a barren and lifeless surface, so why can it absorb the thunder?

Before he could think about it, the thunders, after entering the starry sky, rushed back fiercely, but their color was different, from the original white to gold, but the momentum was still as shocking.

Lin Shiyi had nowhere to hide and was entangled by the thunder, but he was surprised to find that he was not hurt at all and the strength in his body was slowly replenishing.

As more and more thunders were transformed, the golden light in Lin Shiyi's body overflowed. He was extremely excited and quickly gathered the golden light in his body and stored it one by one. Then he used the extra golden light to practice the fourth level of the Falling Star Sword Technique.

He had already memorized the formula of the fourth level sword technique by heart, and now that he had enough strength, it would come naturally. However, he was still unclear about the power of the fourth level sword technique.

He chanted the sword formula and concentrated his strength on his sword finger. For a moment, under the golden light, a strong aura emanated from his body, blowing away the calamity clouds around him without thunder and lightning.

Feeling that the sword technique on his fingertips had reached its limit, Lin Shiyi swung it vigorously towards the empty space in front of him.

A golden sword light flew forward rapidly. It seemed to have no power on the surface, but wherever the sword light went, huge cracks were cut into the starry sky. Not only that, when it reached a very far distance, it actually hit an equally dim interface. With a loud bang, a deep pit was blown out on the interface.
