Castle of Black Iron

Half a month later, somewhere in Mountain Ruins...

The air-floating mountain ranges lasted 600 miles and formed a continuous patch of land like islands in the void. The highest mountain peak was over 100,000 m. Like sharp swords pointing into the heavens, these lofty mountain peaks were accompanied by bottomless valleys among them...

The higher the mountains were, the deeper the valleys would be.

In the bottomless valleys, there was looming white fog. The white fog covered rugged odd-looking stones. These valleys couldn't see sunshine all the year round; because they were always shrouded with fog. Therefore, those rugged odd stones became the gathering place of some bizarre living beings which favored dark.

At this moment, Zhang Tie was hiding somewhere at the hillside, from where he could overlook the entire valley. Compared to the barren valley below, there were dense woods and many grottoes at the hillside, which were suitable for ambushing.

A red centipede longer than 1 m slowly climbed up. Right under Zhang Tie's eyes, the centipede appeared to have sensed something abnormal as it became shortly still. Tentacles quivering, it started to explore the situation in the air.

"Go away..." Zhang Tie sent a spiritual order to the centipede, which hurriedly sneaked into the grasses beside it and escaped away, causing rustles.

After driving away from the centipede, Zhang Tie took a look at the valley again only to see nothing.

Hiding in the pit, Zhang Tie had forgotten how many times he had observed the situation in the valley. However, he could see nothing within thousands of miles per time. The latest demon general that Zhang Tie noticed was 12 days ago. In the evening, that demon general flew by over 1,300 miles away, crossing the skyline like a meteor. Given its speed, Zhang Tie judged that it should be a fire immortal general.

At that time, as he and Immortal Being in Cloud had set a "trap" here, Zhang Tie didn't think it was necessary to catch that one at the cost of scaring more demon generals away. Therefore, he let that demon immortal general go.

But now, Zhang Tie started to regret watching a complete fire chakra flying away.

After that demon immortal general flew away, no more demon immortal generals appeared in Zhang Tie's eyes, even in this valley where a "powerful trap" was set.

Zhang Tie finally lost his patience today. He had stayed in this pit for half a month only to see insects crawling in front of him every day. Nobody else could stand that. If not the possibility that he might get some fire chakras of demons, Zhang Tie would never have stayed here so long.

After a few hours' stay, when the dark gradually fell, Zhang Tie finally lost his patience completely. Heart burning with fury, Zhang Tie instantly flew out of the pit where he had been hiding in for over 10 days. After entering the valley, he kicked an ox-sized huge stone into pieces, scaring all the insects and animals in the surroundings back into cracks or pits where they used to hide in. At the same time, Zhang Tie swore, "Trap sh*t..."

At this moment, Immortal Being in Cloud also jumped out of a pit in the nearby. In the blink of an eye, he had come to Zhang Tie's front. Watching Zhang Tie with an embarrassed look, he explained, "Erm... erm... the trap was always available before... I've tried it many times. Why... why doesn't it work this time? This place is called Tranquil Valley. It's gloomy and hidden. It's covered with Tranquil Grasses. Wind spider demon immortal generals like to rest and lurk in such places most. Additionally, the paste that I daubed on the stone could be smelt by wind spider demon immortal generals from 600 miles away. They would definitely come over here to check it. By then..."

Immortal Being in Wood's idea was good, but the fact was unpleasant. It was like how a hunter set a trap. Sometimes, the trap could capture preys; sometimes, the trap could catch nothing until it was rotten and collapsed.

"Didn't you say that wind spider demon immortal generals would fall into the trap in 3 days on average, 5 days at most? It's already half a month! But none of them was trapped. Did you really catch any wind demon immortal general with such a trap before?" Zhang Tie watched Immortal Being in Cloud with doubts.

"It's real. When I set a trap a few years ago, I killed two wind spider demon immortal generals with my friend. If not a fire spider demon general was attracted, we could continue to catch other demon immortal generals with that trap..." Immortal Being in Cloud frowned with a confused look, "I also wonder why it became useless this time. Have all the spider demons changed their temperament? That's impossible..."

"What did you daub on the stone?"

"It's a mixture of essence of 10,000-year-old Tranquil Grasses in flower, poison glands of spider demon immortal generals and the other elixirs. This recipe is classified. Average people don't know about it. A drop of it cost me dozens of element crystals..." Immortal Being in Cloud said with a bitter smile. He didn't tell Zhang Tie about this "secret" before; however, he could only explain it at this moment.

"I spent a lot in getting one vial. Only wind spider demon generals could catch its odor by their nose. If spider demon immortal generals eat the essence of 10,000-year-old Tranquil Grasses which had been in flower, the toxicity in their battle qi could increase by more than 30%. It could increase their battle force greatly. Ordinary spider demon generals could never withstand such a big allure..." Immortal Being in Cloud said as he scratched his head. Closely after that, he suddenly changed his face as if he had recalled something, "Err, did that old guy sell me a fake good? No, I have to settle accounts with him..."

Watching Immortal Being in Cloud's changing expressions, Zhang Tie became speechless. At this moment, he couldn't beat this old man and blame him for wasting half a month. If Immortal Being in Cloud really bought a "fake good", Zhang Tie could only accept the fact. Over the past half a month, he just took it as a rest. What else could he do? No matter what, Immortal Being in Cloud was his half guide in Mountain Ruins. He had learned a lot from this guy. He didn't suffer a loss at all.

Therefore, Zhang Tie became gradually composed. After taking a look at Immortal Being in Cloud, he said, "If you want to settle accounts with someone, I will not go there with you. Let's bid farewell here. Green hills remain unchanged, green waters flow forever. Hopefully, we could meet each other again in the future..."

"Ah, Li, won't you come with me..." Immortal Being in Cloud still wanted to ask Zhang Tie to stay while rolling his eyes smartly, "Li, as long as you and I find that old guy and get the quality good from him, we could continue here. When we kill demon generals, I only need 40% of the profits, you could take the 60. Additionally, Li, you're not familiar with Mountain Ruins..."

"Haha, it doesn't matter. I will be familiar with it after taking a look around. Additionally, I could make hundreds of thousands a second, I could really wait for any more. I've got something important to deal with. See you..." After leaving the words, Zhang Tie instantly rushed into the sky. With a few flashes, he had left Tranquil Valley and disappeared...

Seeing off his "good helper" whom he had fetched with great efforts with a pitiful look, Immortal Being in Cloud slightly frowned as he mumbled, "Hundreds of thousands a second, what does that mean..."

After standing there for a short while, when he couldn't see Zhang Tie any longer, Immortal Being in Cloud took out of a red jade vial from his space-teleportation equipment. After taking a look at it, he immediately threw it onto a stone in the far, breaking it into pieces and spraying liquid everywhere.

"Old guy, how dare you to cheat me with a fake good? I will demolish your nest this time..."

After making a decision ferociously, Immortal Being in Cloud stamped to the ground once as he flashed towards another direction...

The deep valley was tranquil; the white fog was rolling. Only after a short while, this place had become as tranquil as before...

One day later...

With a bang, a powerful battle qi crossed the air which cleaned up the rolling white fog in a split second, exposing an open land at the bottom of the valley being covered with rugged odd stones. With a red flash, 7 terrifying and powerful spider demon generals appeared on the ground.

They were 7 powerful spider demon immortal generals. The one ahead of the other 6 was in black metal armor, exposing 6 arms. In a bloody cloak, his qi was domineering. It was this spider demon general who had cleaned up the white fog across the valley with only one strike. At this moment, if Zhang Tie was here and saw this spider demon immortal general, he must widely open his mouth. Given its qi, this spider demon immortal general was a powerful sage-level knight.

Even though Zhang Tie was not here, if someone else saw the bloody cloak behind this spider demon immortal general, he could also judge the identity of this spider demon immortal general even though he couldn't sense its domineering qi. Among the demon immortal generals in Motian Realm, those in bloody cloaks were supreme immortal generals, namely sage-level knights.

During the past half a month, when Zhang Tie and Immortal Being in Cloud stayed here, they didn't get sh*t; however, soon after they left here for a day, 7 demon powers had arrived here at the same time...
