After he went out, he flew into the air and invoked the Lightning Vessel Sigil divine ability. This caused the blue bolt of lightning on his forehead to glow and throb.
The vessel sigil on his head began communicating with the world. It performed this communication by using his Lightning Call talent. The Lightning Call talent was the talent that the vessel sigil had taken and used as its foundation.
With this talent, the vessel sigil technique called to the sky, and the sky replied. The clear sky quickly became dark as storm clouds gathered and obscured the light of the sun. Then lightning began to appear in the dark clouds.
The sound of the lightning was loud. They shook the world as if the sky was angry with everything. It looked like a strong storm was about to appear.
Blue streaks of lightning streaked through the sky. These lightning bolts grew in number and power very quickly.
After the lightning bolts reached a saturation point, they combined into one large bolt of lightning. That giant bolt of lightning then fell to the ground towards Arthur.
Arthur was ready for this. He raised his head to the sky as he welcomed the descent of the mighty bolt of lightning.
The lightning bolt crashed onto his head. Then it sank harmlessly into the blue lightning mark on his head.
The vessel sigil technique engorged itself on the lightning bolt. Because of the supply of heavenly lightning, it swelled in size and glowed brighter and brighter. It looked as if the sky was feeding it.
Unfortunately, the lightning vessel sigil technique had limited space. It couldn't absorb lightning indefinitely and had to stop at some point.
Arthur had only mastered the lightning vessel sigil technique to 10%. This meant that the space within the mark could only contain heavenly lightning that was equivalent to 10% of the energy capacity of his golden core.
To be exact, the space in his head could only contain 102,400 units worth of energy since his golden core has a capacity of 1,024,000 units. Compared to the amount of lightning that the sky is willing to give him, what he can hold is just a drop in the bucket.
Actually, even his entire golden core couldn't store everything the sky was willing to give him. Not only is heavenly lightning vastly more powerful than the lightning he can produce, but it is also far more in quantity than he can produce.
So he has to give up absorbing the lightning from the sky, and he has to do it quickly before he loses control of the storm. He did this by deactivating the Lightning Call divine ability. This caused the storm to lose interest in him.
The lightning bolt that was falling from the sky ignored him and struck the ground beside him. The strike caused a loud explosion of sound, light, and heat. A large crater appeared in the place where the lightning bolt had struck the ground. Even his floating island rumbled because of the impact.
He saw this and said, "Fortunately, I rose into the air earlier. If I were still on the ground when that happened, I would be screwed."
He has the Lightning Resistance talent, which makes him slightly immune to lightning attacks and damage. But at this stage, that talent is mostly useful against other cultivators at his rank. It is next to useless against heavenly lightning.
The raw power of the bolt is also something that is out of his league. So if he had been on the ground when the bolt struck the ground, he would have been injured terribly, even if he didn't die.
The scene of destruction he just witnessed made him sigh in relief that he was nowhere near the crash when it happened, but it also made him look forward to the kind of power he could wield with the lightning vessel sigil technique.
The power of the lightning vessel sigil is unknown. But according to records from previous wielders, this single technique can be used to harm and even kill nascent soul cultivators. This is a reliable estimate since Void Claw had achieved something similar with his vessel sigil technique.
If there is one disadvantage of the lightning vessel sigil technique or any vessel sigil technique, it is their need for preparation. Vessel sigil techniques can't be used anyhow. They must first be prepared, and this preparation will take time.
In the case of the lightning vessel sigil technique, the preparation involves calling lightning from the sky and storing part of the lightning for future use. This is not something he can do in the thick of battle when he urgently needs the power of the lightning vessel sigil technique.
But now that he has made the necessary preparations, he will have the confidence to use the technique. The only thing to watch out for is to make sure to replenish the heavenly lightning anytime he uses it.
After getting what he wanted from the storm, the storm dispersed, and the dark clouds also disappeared. This caused the bright light of the sun to return to shine on his floating island.
With this done, he went down to the forest below to make the preparations for his second sigil technique. This is the wood vessel sigil technique, and it needs trees to give him the energy he needs.
He found a giant tree in the forest. Then he went up to it and touched it with his hand.
This physical contact between them enabled him to use the Plant Affinity and Communications talent on it. Once this talent took effect, he began to hear what the tree had to say.
The tree had a lot to say. It needed more water and wanted to strangle all the trees around it. It also wanted all the bugs crawling all over it to die.
Everything the tree had to say was murderous and about violence. It didn't have a single peaceful thing to say.
