Qingyang thought about this before coming here. It is said that there will be associated Tiancai and Dibao in the thunder pool. The lightning power here is so strong that there may be good things at the bottom of the pool. Just now, Qingyang was disappointed to see that the bottom of the pit was bare. Now he knows that the good thing is blocked by the iron eating beast. The value of the spirit wood at the bottom of the pit is definitely not much worse than the Dragon horn root he got from the Jiaolong ruins many years ago. It may even be a treasure of the same level.

At the beginning, Qingyang once heard that the ancestor of the Zhou family said that the Dragon horn root is the heaven and Earth Spirit root and the main material used to refine the sky mending pill. If it is also a treasure of the same level as the spirit wood, it may also be a heaven and Earth Spirit root. The Dragon horn root is wind attribute. The spirit wood grows in the thunder pool and contains terrible thunder attribute energy. It must be thunder attribute, that is to say, If you get him, you will have two kinds of heaven and earth spiritual roots, and you can refine the two-color sky mending pill.

The sky mending pill is used to replenish the spiritual roots of friars. The more spiritual roots of the golden pill friars, the more perfect the Yuanying formed. After breaking through the Yuanying, the more powerful the friars will be. Originally, the spiritual roots of the five elements of Qingyang are much more powerful than other friars. If they can supplement the two spiritual roots of wind and thunder, it will be easier for him to break through Yuanying, form Yuanying more satisfactorily, and have stronger strength in the future.

For low-level friars, the more spiritual roots, the more difficult it is to cultivate. It can be said that duolinggen friars who can cultivate the golden elixir perfectly are rare. The spiritual roots of heaven and earth are so rare, and it is even more difficult to supplement the spiritual roots the day after tomorrow. There are almost no five spiritual roots friars like Qingyang, let alone seven spiritual roots friars. How terrible should Qingyang exist once it forms a Yuanying?

Before, Qingyang chased and killed the iron eater just to value some dark stones for the body of the iron eater. He didn't want to get it. If the price to kill the iron eater was too high, Qingyang would probably give up. But now with the spirit wood at the bottom of the pit, Qingyang has changed his mind. He won't give up anything this time, even if he pays a big price.

In fact, Qingyang doesn't know that this spirit wood is not only useful for friars, but also for monsters and Warcraft. The reason why the iron eater keeps the spirit wood until now is not that he doesn't need it, but that he is reluctant to give up. The iron eater is now the strength of the Ninth level peak, and it's not far from the breakthrough.

It's just that it's very difficult for monsters and Warcraft to advance. The iron eater hasn't been sure yet. His original plan was to keep the spiritual roots of heaven and earth and use them at the critical moment of breakthrough. With the help of the huge energy obtained when refining the spiritual roots of heaven and earth, he may be able to advance successfully.

As a result, I didn't expect that I met a hard stubble when I went out today. Not only did I not hunt food, but I was chased to my nest by the other party, which also exposed the spiritual roots of heaven and earth that he had guarded for countless years.

The iron eating beast had no choice but to fight hard. At that moment, Qingyang made up his mind. Seeing that the iron eating beast had rushed and the distance between the two sides was less than ten feet, Qingyang quickly sacrificed the five element sword array.

Qingyang seems to have forgotten that he still has to resist the lightning constantly released by the thunder pool, and his five giant swords have just received a lightning energy. Before they can be released, they can only forcibly use the five element sword array with that lightning energy to kill the iron eater.

Qingyang was in a hurry. In order to protect his treasure, the iron eater was dazzled by hatred. He didn't notice the difference between the five element sword array and the one previously displayed outside. In the twinkling of an eye, the two sides collided with each other, and the whole cave shook with a loud noise.

Such a big noise would have collapsed if it were an ordinary cave. Fortunately, the whole Wanfeng mountain is piled up with metallic materials. After countless years of solidification, it is difficult to be damaged by general impact. The cave just shook a few times, shaking layers of sand and dust, and did not collapse.

The huge impact pushed Qingyang back several steps before he stood still. At the same time, his face turned white and he felt a stabbing pain in his mind. It was not the reverse bite of the five element sword array, but because the five giant swords contained lightning energy, which was already overloaded. Then Qingyang forced the five element sword array. Under the double pressure, the magic weapon sword body was slightly damaged, The life magic weapon is connected with the monk's mind. If the magic weapon is damaged, the mind will also be affected.

In fact, Qingyang had expected this for a long time, but the situation was urgent at that time, so it was necessary to do so. As for the damage to the magic weapon, you can only go back and slowly warm up, and you can recover in three or five months.

After Qingyang paid such a high price, the iron eater was not much better. While Qingyang retreated, the iron eater screamed and rolled out and fell to the bottom of the pit.

At this time, look at the iron eater. Although the scales are still complete, there is a slap big wound on the back where Qingyang once hurt it. It is dark inside and constantly seeping black blood. The iron eater is depressed and seems to have been seriously hurt.

Qingyang didn't expect that the five element sword array was so powerful that it almost cost half the life of the iron eater. According to this situation, the battle can be solved by two more times at most.

In fact, this is normal. The iron eater has lived in the thunder pool for a long time and has adapted to the lightning stroke in the thunder pool. If it is only lightning, it will not only be harmless to the iron eater, but also enhance the strength of the iron eater and repair the damage to his body. It is a great tonic.

But lightning is destructive after all. Once it is combined with Qingyang's five element sword array and exceeds the endurance of iron eaters, there is only harm and no benefit. Just like eating with people, eating in moderation is a good thing. If you eat too much, you may be burst.

The power of the five element sword array containing lightning energy has doubled. One attack makes the iron eater lose defense, and the other attack makes the iron eater suffer heavy damage. Qingyang didn't expect this result, and the iron eater didn't expect it.

Of course, although this method is powerful, it will do great damage to the magic weapon. After it is used up, you have to spend energy on repairing and warming the magic weapon. If you can avoid it in the future, you should use it as little as possible to avoid causing greater damage to your own life magic weapon. Fortunately, the iron eater has been seriously damaged. Now Qingyang is sure to win even without the five element sword array.

Perhaps it was affected by the battle just now, and the Leichi also fell into stagnation at that moment. There was no new lightning for a long time. However, after a delay, the Leichi seemed to recover, and gradually lightning was brewing in the deep pit. Qingyang couldn't care about the iron eater at the bottom of the pit, so he had to sacrifice five giant swords to resist the lightning attacking him.
