Fortunately, what Xiao An was worried about did not happen, but the thunder bead, which was originally as calm as water, suddenly boiled after coming into contact with the dark purple thunder ball, like boiling water, and countless small bubbles were generated from the inside of the thunder bead, and suddenly burst after rising to the surface of the thunder bead.

When the tiny bubbles burst, wisps of thunder and lightning were released, and this ray of thunder and lightning did not rage in Xiao An's body, but appeared directly outside Xiao An's body. After a while, countless subtle thunderbolts were woven into a layer of "light yarn" outside Xiao An's body.

Xiao An breathed a sigh of relief, fortunately he didn't have ashes, but he didn't know what Lei Zhu would become.

Xiao An didn't wait long, and the thunder bead regained his calm, but the thunder bead, which was the size of the dragon's eye just now, had shrunk by more than half at this time, but the color was a little thicker than just now.

Before Xiao An could understand what was going on, a low shout sounded in Xiao An's ears: "Continue to absorb the heavenly thunder." ”

After hearing this voice, Xiao An did not immediately run the exercises, but planned to observe the state of the thunder bead in his body first. At this time, the divine consciousness that was dormant in Xiao An's body suddenly took action, directly controlled Xiao An's body, and began to run the exercises.

At this time, although Xiao An was clear, he could no longer control his physical body, and could only watch the changes in his body like an outsider.

Under the control of the big demon, wisps of heavenly thunder were constantly absorbed by Xiao An, and then they were quickly absorbed by the thunder beads, and the speed was several times faster than when Xiao An controlled it himself.

After a while, the thunder bead in Xiao An's body slowly returned to the size of a dragon's eye, but the big demon had no intention of stopping, and continued to absorb and refine the heavenly thunder.

Seeing that the thunder bead grew from the size of a dragon's eye to the size of a walnut in a circle, Xiao An's heart jumped to his throat. Fortunately, there is the thunder and lightning control from the big demon, and the thunder bead is not the slightest instability.

Immediately, countless bubbles appeared on the surface of the thunder bead, and because the thunder bead was much larger, the number of bubbles was several times more than the first time.

The generation of each bubble will absorb some spiritual power, and after a while, Xiao An found that the spiritual power in his body was about to be exhausted. But at this time, Xiao An couldn't control his body at all, and he couldn't even speak.

In a hurry, Xiao An controlled his divine sense and began to violently impact the other party's prohibition. Xiao An's actions were beyond the other party's expectations, and even the thunder beads in Xiao An's body showed a trace of fluctuations, which frightened Xiao An and the big demon.

"Hmph!" A cold snort sounded in Xiao An'an, shaking Xiao An in a trance. Fortunately, the other party only punished slightly, otherwise it would be more than just a trance.

A drop of dark red blood flew out of the cave and flew towards Xiao An.

During the flight of blood, a trace of demonic qi was quickly peeled off from it, and when it flew in front of Xiao An, the blood had already turned from dark red to vermilion, and was thrown into Xiao An's mouth.

It was a drop of blood, but it was like a hard block of ice, and only the place where it came into contact with saliva slowly melted a little.

This silk of dissolved blood flowed down the throat into the stomach and intestines, and under the action of the stomach and intestines, it was quickly broken down into various nutrients and violent aura.

This little bit of blood, which was smaller than a hair, released more aura than a few spirit stones, although these aura instantly made up for the spiritual power in Xiao An's body, but the violent spiritual power was also constantly impacting Xiao An's meridians and internal organs.

Fortunately, Xiao An's physical body is much stronger than before, and the nutrients in the blood are quickly absorbed and used to repair the injured area. With the absorption of these substances, Xiao An's body repaired faster and faster, gradually exceeding the speed of destruction.

Xiao An, who had just breathed a sigh of relief, immediately became nervous again, because a demonic aura full of killing and destruction rushed towards Xiao An's mind like a tide.

Although most of the demonic qi in the blood had been dissipated before it fell into Xiao An's mouth, there was still a small amount of demonic qi that had dissolved into the blood. In the process of the blood being absorbed by Xiao An, these demonic qi were gradually released.

The prohibition used by the big demon to isolate Xiao An's divine consciousness became precarious under the impact of the demonic energy, and just when this demonic energy was about to break through the prohibition, another ball of thunder and lightning flew out of the demonic cavern and threw it into Xiao An's body.

This thunder and lightning did not rush towards the "thunder bead" in Xiao An's body, but rushed towards Xiao An's Zhihai, and turned into a huge net to protect Xiao An's Zhihai, and that demonic energy turned into nothing after touching the giant net.

In this extremely tense situation, Xiao An's mind became more sober, and even the process of the change of the thunder and lightning just now could be seen clearly.

With the passage of time, the thunder beads in Xiao An's body kept repeating the process of "growing-shrinking-growing-shrinking", and the demonic qi also appeared one by one and was wiped out by the thunder and lightning giant net.

When the energy in this drop of blood was completely absorbed, the "thunder bead" in Xiao An's body finally stopped changing, and at this time, the thunder bead had turned into a demonic dark purple, and its volume was only a little smaller than a walnut.

The thunder beads in Xiao An's body reached saturation again, and the thunder and lightning in the sky became more and more sparse.

The divine consciousness that controlled Xiao An's physical body suddenly all withdrew, Xiao An finally regained control of his physical body, Xiao An found that with the replenishment of the blood of the demon beast, he was now not only full of spiritual power, but also felt that his physical body was much stronger, especially the thunder bead in the body, both in size and quality, far exceeded the description in the exercises.

This time, the big demon did not continue to stop him, and Xiao An hurriedly got up after receiving the merit and stood aside respectfully.

"Senior, junior has finished practicing, I wonder if the senior has any instructions?" Xiao An cautiously asked the other party.

Although he didn't know why the other party helped him absorb the heavenly thunder, Xiao Anxin knew that this move would definitely bring benefits to the other party, and now he was worried about whether the other party would let him go.

"You can go!" After a while, the big demon in the cave replied, and there was a faint sense of fatigue in his voice.

Xiao An didn't dare to delay, and hurriedly performed the exercises and left after withdrawing for hundreds of zhang. Not long after Xiao An left, the thunder and lightning no longer fell to the ground, and all the dark clouds in the sky dispersed.

At this time, a simple voice sounded from the cave: "Mother, dear, you, for, what, what, no, receive, return, that, group, this, life, thunder, source?"

"Hurry up, your small transfiguration celestial phenomenon may have attracted the primordial infant monk of the human race. As soon as he finished speaking, he saw two black shadows fly out of the cave and fled into the distance.

At the same time, a figure also flew out of the mountain dozens of miles away, chasing in the direction of the big demon's departure.
