Fang Yan didn't see all the passages, as he walked forward, there were a few more turns in front of him, gradually overlapping with the path in Fang Yan's memory, it seemed that this was the passage that the group of wood worms brought themselves in.

There was no danger along the way, the entire formation had completely lost its core energy, there was no trace of mana fluctuations, and Fang Yan didn't take much effort to get out of this formation, and as soon as he stepped out of the formation, Fang Yan felt his scalp tingle.

There were lightning flashes in all directions, I don't know how many thunder arrays similar to the formations behind him, some of them also had no mana fluctuations, but many of them continued to operate, Fang Yan thought of what he had encountered outside the Thunder Castle, presumably the lightning was released by one of these formations.

Fang Yan didn't dare to move, stayed by this thunder array and quietly watched the dozens of flashing thunder lights around him, and gradually found that it seemed that these thunder lights didn't notice him, or he wouldn't notice himself at all, thinking about what happened before, it seemed that their attacks were aimed at the demons and evil spirits outside the city that were close to the Thunder Castle.

Fang Yan sacrificed the peach miasma armor, and put the Yuxi page in front of him, to deal with the powerful attack, the Yuxi page has the incomparable advantage of other magic weapons, after sacrificing these two magic weapons, Fang Yan walked towards another formation that stopped running, since there was a wooden heart worm in this one behind him, maybe there were other ones.

The Immortal Dialect searched for several formations in a row and found nothing, each formation was empty, nothing, neither mana fluctuations, nor any remaining objects, let alone wood heart worms or wood heart worm eggs.

Looking at the formations that are still running in front of you, you can know how powerful these formations are, even those dead formations without energy, Fang Yan can enter freely with his illusion breaking eyes, but if he wants to break it, he still has no power to get the formation materials, and Fang Yan has no choice but to give up the idea of arranging such a formation in front of his cave.

"Hey, what is this? Fang Yan entered a thunderstorm that had stopped running, and suddenly found a wooden block in the center, and there was a trace of spiritual air circulating on it, but it was very faint, like a faint candlelight, which would be extinguished at the slightest movement.

Fang Yan took the wooden block in his hand, but there was no doubt that it was the wooden spiritual power circulating in it, but what surprised Fang Yan was that there seemed to be a trace of thunder spiritual power in it, which was much weaker than the wooden spiritual power.

"Old man, come out and see what this thing is, whether it is something that arranges a thunder array. ”

As soon as the old man revealed his senses, he saw a faint but swift flash of thunder, and with a stabbing sound, Fang Yan heard the old man's miserable cry: "Boy, do you want my old life?" ”

Fang Yan didn't expect the wooden block in his hand to be so powerful, and he would take the initiative to attack, and hurriedly probed his divine sense into the ring: "Old man, it's okay." ”

"Well, luckily, it's a small piece, you know what it is, it's thunderwood. ”

"Thunderwood?"

"That's right, the thunder array is rumored to be a formation handed down from ancient times, and it should have been arranged with thunder wood as the base of the formation at that time, but thunder wood was also a very rare thing in ancient times, and it was almost extinct later, I really don't know how there is a fragment of thunder wood here. ”

"Without thunder wood, people can use other materials instead to arrange thunder arrays, but in order to be much smaller than the original, it is said that thunder arrays arranged with thunder wood can kill monks above the primordial infant. ”

"You think that this thunder wood was the core formation base of this thunder array in the first place, but unfortunately after years of consumption, there is not much spiritual power in it, otherwise you can consider using it to refine a magic weapon, the two systems of wood and thunder, can definitely be proud of the same level. ”

"Boy, where the hell have you been, you just saw the Wood Heart Worm, and then the Thunder Wood. ”

"Didn't I say hello to you when I came in, it's what you said about the Killing Plains, but this is a castle in the Killing Plains, and the Terrans of the Dark Demon Realm call it the Thunder Castle. ”

"What, you really entered the Killing Field?" the old man didn't expect that under his own persuasion, Fang Yan still entered this murderous place: "You didn't encounter the Fierce Soul?"

"I did, I didn't, how could I end up where I am now, but it's okay, if it weren't for them, I wouldn't have been able to touch the Wood Heart Worm. Then the dialect was briefly introduced to the old man.

"Even if you kid has a big life, you dare to swallow the Shenglong Pill continuously, even the Jindan monk doesn't dare to swallow it like this, if you don't meet the wood heart worm, you still want to restore your cultivation, and you can't save your life. ”

"No, old man, why didn't you say it when you were alchemizing. ”

"How do I know that you have a Dan prescription and can refine Dan, I don't even know this bit of common sense. ”

The frightened dialect patted his chest, and after a while he said again: "Okay, old man, it's not dead after all, don't you, do you say that this thunder wood is useless?"

"Well, there is only a little spiritual power left, and if it is refined, it is at most a medium-grade or even low-grade treasure, which is not of much use, and consumes too much. ”

Fang Yan was a pity, but these forced could not come, so he casually threw this piece of wood into the Qiankun pot, and then continued to walk towards the next death battle.

What Fang Yan wants most now is to find the wood heart worm, the spiritual root, which monk doesn't want it, he already has half of it, as long as he finds even one more, Fang Yan is also confident that he will refine the entire wood spirit root, the previous wood spirit silk has been used to heal his wounds, only the latter ones are really refined with mana, and only a small part is absorbed, you must know that these things can refine the wood spirit root, Fang Yan will not do anything like this, even if the body is injured for a few more days, he will not give up the opportunity to refine the wood spirit root.

But it's too late to say anything now, unless one more wood worm is found.

The hard work paid off, although Fang Yan didn't find another wood heart worm, nor did he find a wood heart worm egg, but he found a food that was wrapped in wood spirit silk like himself, and looked through the wood spirit silk, inside was an unknown demon worm, the size of a fist, without a trace of breath, and it had been dead for a long time.

Fang Yan didn't have any good feelings for monsters, even if he had a lot of demon subordinates, he didn't want to think about it, so he ripped off the wood spirit silk, this time he didn't sloppily use the fire to roast, but swallowed it in the stomach, and used pure mana to refine, although there are still many places in the body that need to be repaired, but Fang Yan did not separate a trace to heal.

"Old man, come out and see if I have a wood spirit root. ”

A few hours later, Fang Yan excitedly shouted into the ring, he had completely refined the wood spirit silk, and before he finished refining, Fang Yan felt that his body seemed to have changed, and his perception of spiritual energy had improved a lot, even in the dark demon realm where the spiritual energy of heaven and earth was not strong enough, Fang Yan could also sense their existence.

The dialect is ninety percent sure, he should have refined a wood spirit root, and for the sake of insurance, he still asked the old man to come out and confirm it.

"Hey, really, you have refined another Wood Spirit Silk? Your kid has been really lucky lately, this kind of anti-heaven thing like Wood Spirit Silk can be encountered one after another, but even if it is a Wood Spirit Root in the Black Demon Realm, it is not very useful, only by returning to the cultivation realm where the spiritual energy of heaven and earth is sufficient, your cultivation speed can be greatly improved. ”

"Old man, you don't know this, I have a lot of spirit stones on me, even if I can't go back for a hundred years, I don't have to worry too much. ”

Knowing that he really refined the wood spirit root, Fang Yan had already taken out a spirit stone and tested it, and the speed at which he absorbed the spiritual energy was more than twice as fast, and the spirit stone used in the original fighting method was definitely not able to make up for the consumption, but now it is almost the same, if you use a medium-grade spirit stone, there will be a surplus, thinking that there are still tens of millions of spirit stones on your body, Fang Yan is not worried for a while, and he does not have to worry about the problem of running out of mana, and he can use the spirit stone to kill the opponent in the future.

Of course, it is still impossible to confront the opponent above the demon commander, in the black demon world, due to the suppression of the divine sense, his biggest help puppet man can not be urged, the queen bee beast, the red cicada is still very unsuitable for the erosion of the black demon qi, and now the people who can help themselves have become a group of their own demon subordinates, as well as the soul bones left in the Huang family village, and the butterfly that is still sleeping.
