After walking forward for a distance, the cave had come to an end, and a huge cave appeared in front of him, this cave was a hundred zhang square and dozens of zhang high, no need to ask, this must be the old nest of the iron-eating beast, Qingyang could even faintly see the shadow of the iron-eating beast.

Before Qingyang could take a closer look at the situation in the cave, suddenly, a bright light flashed in front of him, and then he saw an arm-thick thunderbolt slashing towards his head.

This thunder and lightning came without warning, and Qingyang didn't expect that thunder and lightning would suddenly appear in the cave of this iron-eating beast, and he didn't have time to react otherwise, so he could only use his divine thoughts to drive the Yuhai Pingbo Sword and the Yellow Pole Smoke and Dust Sword to resist.

I saw that the Yuhai Pingbo Sword swung slightly, forming layers of water curtains in the air, blocking the front of the thunder and lightning. In Qingyang's entire set of natal magic weapons, the defense power of the Yuhai Pingbo Sword is second only to the Huangji Smoke and Dust Sword, and the released water curtain can easily block the attacks of monks of the same level in normal times, but this time the attack in the face of thunder and lightning seems to have lost its effect, and it is easily penetrated.

Fortunately, at this time, the Yellow Pole Smoke and Dust Sword had also been deployed, and in the process of flying up and down, a thick yellow sand and smoke and dust were released, which instantly submerged the thunder and lightning, and then a bang was heard, and the Yellow Pole Smoke and Dust Sword flew back upside down, and the yellow sand and smoke and dust in the sky dispersed, and the thunder and lightning also disappeared.

Finally dealt with it, but before Qingyang could breathe a sigh of relief, the second thunderbolt had been brewing in the air, and it was slashing towards Qingyang again, the interval between the two was too short, Qingyang had just turned the Yellow Pole Smoke and Dust Sword back, the yellow sand and smoke had not all been released, the thunder and lightning had already come to him, this time the response was a little hasty, and the thunder and lightning quickly dispersed the yellow sand and smoke released by the Yellow Pole Smoke and Dust Sword, and the remaining small half of the energy directly hit Qingyang.

Don't underestimate the small half of the remaining energy, the power is almost equivalent to the fatal blow of the late Jindan monk, if it hits the body directly, even the Yuanying monk can't afford it, but fortunately, Qingyang has already made a lot of defensive measures outside the body before, saving his life.

The thunder and lightning quickly penetrated the layers of defenses on Qingyang's body, and the energy was gradually exhausted, and when the thunder and lightning disappeared, all the defenses that Qingyang had arranged before were broken, not only that, Qingyang was also affected by the remaining thunder and lightning, and his clothes were burned to black ash, his hair was bursting apart, his whole body was sore, and the whole person almost lost his ability to move.

For more than a hundred years of cultivating immortals, Qingyang has experienced countless battles, among which some people have used thunder attribute talismans, and Qingyang has also tried the position of being struck by lightning, and the feeling is very similar to today. The thunder attribute talisman is not only powerful in attack, but also can cause delay in the monk's action, and now Qingyang's reaction ability has greatly decreased, if he does it a few more times, he will definitely not be able to hold on.

But there are some things that don't come if you don't want him, the second thunderbolt just disappeared, and the third thunderbolt followed, and then Qingyang saw clearly that the thunder and lightning were not generated out of thin air, but shot out of a deep pit in the cave, and the iron-eating beast was hidden inside.

The thunder and lightning in the pit not only attack Qingyang, but also attack the iron-eating beast in the deep pit, but unlike Qingyang, the iron-eating beast does not seem to be afraid of lightning strikes, and the thunder and lightning hit his body, only producing a trace of electric light, which quickly disappeared, and the iron-eating beast not only did not feel pain, but would show a trace of enjoyment, which made Qingyang very surprised.

Qingyang observed with his divine thoughts, there were no other creatures around the pit, and there was no formation or utensils that could release thunder and lightning, and the thunder and lightning seemed to be naturally formed in the pit, this situation Qingyang had heard of, but had never seen it, this pit should be the legendary thunder pool.

The thunder pool is generally a deep pit that can naturally produce thunder and lightning, this kind of thing is very rare in the world of cultivating immortals, Qingyang has only heard some rumors about this before, I didn't expect to encounter it here, and it was also regarded as a lair by this iron-eating beast, no wonder the defense of this iron-eating beast is so strong, it is estimated that it is because it has been trained by too many lightning strikes, just now Qingyang saw with his own eyes, when the thunder and lightning disappeared into the body of the iron-eating beast, the defense of the iron-eating beast seemed to have increased, even the parts that were injured by Qingyang before, The wound seems to have improved a lot.

The thunder and lightning released by this thunder pool in front of him can even penetrate Qingyang's natal magic weapon, and the power is not bad, it seems that the level of this thunder pool is still very high, since he recognized that this is the thunder and lightning released by the thunder pool, the rest of the things will be easy to do, Qingyang was stunned, his body retreated sharply, and before the third thunderbolt approached him, he retreated to the passage behind the cave.

Because the thunder pool is fixed, the lightning in the thunder pool will also have a distance limit, and if it exceeds a certain range, it will lose its power, so it is very easy to dodge, just retreat to a safe distance. Sure enough, as soon as Qingyang retreated into the passage behind the cave, the third thunderbolt disappeared out of thin air, and then the fourth thunderbolt did not appear.

However, the thunder and lightning in the thunder pool have not disappeared, they are still being generated, constantly consumed, and the iron-eating beast has been staying in the thunder pool, bearing the attacks of these thunderbolts, and the wounds on his body are also healing at a speed visible to the naked eye, which is an eye-opener for Qingyang.

The iron-eating beast was not far away, but Qingyang was confined to a range of nearly a hundred zhang, and he didn't dare to cross the thunder pool by half a step, if the power of the direct attack at this distance was too small, if he didn't attack, he could only watch the iron-eating beast's injury slowly improve, and the previous efforts would be in vain.

It's not just these, it is said that there will be more or less associated heavenly treasures in such a thunder pool, which has a great effect on the monks, the level of the thunder pool in front is so high, and no one has come in for many years, maybe there are really good things in it, and I finally encountered the legendary thunder pool, how can I let it go easily? So what attracts Qingyang now is not only the corpse of the iron-eating beast, but also the heavenly and earthly treasures that may exist in the thunder pool.

If it's just one or two, whether you want to find a way to crack it, or use your body to resist, you can always consume the thunder and lightning, the thunder power in this thunder pool is continuous, but it can't be solved by consumption alone, you must think of a safe way, but what should I do?

Qingyang's mind turned sharply, and he slowly thought of a workaround, remembering that before he started cultivating immortals, when he followed Songhe's old way, he had seen the master pretend to be a ghost and lead thunder and lightning to kill the so-called demons, and at that time, he used an iron chain to introduce the thunder and lightning in the air into the ground.
