Castle of Black Iron

Only after having a few mouthfuls of Nine Heavens Immortal Spring, Zhang Tie had become spirited again. He felt that his battle qi and spiritual energy were going to spill out of his qi sea and mind sea. Additionally, he felt that the remaining bit of resistance from the immortal-human barrier between him and the Energy Realm was instantly destroyed by Nine Heavens Immortal Spring.

Previously, after drinking Nine Heavens Immortal Spring in Emperor NvWa’s Palace, Zhang Tie felt that the gate leading to the immortal emperor was half opened, through which, Zhang Tie could already touch the splendid world by edging in. Now, the gate had been completely demolished by Zhang Tie.

The bizarre colorful energies in various shapes in the Energy Realm were flickering on Zhang Tie’s side every once in a while. Compared to those energies that Zhang Tie sensed before, these energies were clearer and more surging and concrete. They could be touched by hands. The sieve and barrier between Zhang Tie and those energies had long been disappeared. Zhang Tie felt like entering a vast ocean from a river.

Zhang Tie was drinking the Nine Heavens Immortal Spring which many immortal generals were scrambling for even at the risk of their lives to his heart’s content. Across the Motian Realm, nobody else could have such a nice experience, no matter humans or demons.

When Zhang Tie was drinking Nine Heavens Immortal Spring, he felt pretty pleasant. After drinking about one barrel of Nine Heavens Immortal Spring, Zhang Tie turned around and asked Tang Mei with a grin, “Do you want to have some mouthfuls…”

“No need. No matter how much Nine Heavens Immortal Spring I drink, I cannot improve my overall strength anymore. Nine Heavens Immortal Spring only works before one lights his or her immortal chakra. After one lights his or her immortal chakra, it will be meaningless to drink it!” Tang Mei explained with a smile as she stood aside and watched Zhang Tie drinking it attentively.

“Don’t you want to take some back to Emperor NvWa’s Palace? After all, there’s no stockpile in Emperor NvWa’s Palace anymore…”

A few days ago, Zhang Tie had drunk up all the remaining Nine Heavens Immortal Palace in Emperor NvWa’s Palace. However, due to some reasons, it didn’t live up to Tang Mei’s expectations. Therefore, when Zhang Tie caught sight of Nine Heavens Immortal Spring, he had another drink.

“Previously, I didn’t know that the Infinite King Roc Sutra that you cultivated required more Nine Heavens Immortal Spring to completely break the immortal-human barrier and restore your health. After drinking those Nine Heavens Immortal Spring, you only broke the immortal-human barrier basically and sensed the existence of the energies in the Energy Realm. But now, elder brother, you’re already able to absorb the energies in the Energy Realm. You’re destined to promote to an immortal emperor in the future. As long as you integrate the Space Ball of Motian Realm into Castle of Black Iron, Emperor NvWa’s Palace will not need Nine Heavens Immortal Spring anymore in the future!” Tang Mei said calmly.

Zhang Tie stood up as he burst out laughing. “If so, I will take away all the Nine Heavens Immortal Spring!”

“Elder brother, just take it away. There’re a few ponds of Nine Heavens Immortal Spring in Buzhou Mountain, all of which originate from this stone. If you take away this stone, from then on, nobody else will be able to find Nine Heavens Immortal Spring here anymore, no matter humans or demons. That means there will be no demon emperors in Motian Realm. It’s good news for humans in Motian Realm. Demons in Motian Realm are doomed to degenerate and be extinct in the future. When your Castle of Black Iron completely integrates with Motian Realm, demons in Motian Realm will die out…”

That was what Zhang Tie wanted. Besides that Nine Heavens Immortal Spring was a rarity, an important reason why Zhang Tie wanted to take it away was that human and demon sages in Motian Realm would never promote to immortal emperors or demon emperors anymore. From then on, the power contrast between humans and demons would be basically balanced.

At this moment, even if Zhang Tie left Motian Realm, there were still 3 human immortal emperors in Motian Realm. However, there was only one demon emperor hiding in the Demon Realm. Demons could never bear such a sharp difference in power.

When the core area of Mountain Ruins was opened this time, demons might have given up competing with humans in Mountain Ruins. As of now, according to the intelligence that Zhang Tie received from outside Mountain Ruins, not a single demon sage had entered Mountain Ruins. Not until 3 days ago did Zhang Tie know that Star Emperor who has disappeared after the war in Deities’ Plain didn’t come to the core area of Mountain Ruins for possible rarities; instead, he entered the demons’ territory and was plundering unscrupulously in the territory of Versatile Demon Emperor.

Of course, Star Emperor was not selfless; instead, he seized the opportunity period when demons suffered a great loss. He could acquire more benefits in demons’ territory than in Mountain Ruins. Although Star Emperor was selfish, objectively, his raid gave a heavy blow to demons and caused demons to regenerate at a faster speed. This was why Zhang Tie didn’t avenge Star Emperor for attacking Dragon Emperor Immortal Palace in Deities’ Plain. Those who were not of his kind must not stand on his side. Although Star Emperor was cunning, the power of Star Emperor and Star Emperor Immortal Palace also meant the power of humans as a whole. Such a power was beneficial to humans and not to demons.

“I suggest Emperor NvWa’s Palace to keep some Nine Heavens Immortal Spring!” Zhang Tie said with an experienced and profound smile, “There’re too many unexpected things in this world. Many things are variable. Take this Heavens of Light as an instance, previously, neither you nor I could imagine that the most dangerous place in Motian Realm was so peaceful. There might not be any more demon emperors in Motian Realm, but humans must have the confidence to have more supreme immortal generals promote to immortal emperors. As the guardian of humans in Motian Realm, Emperor NvWa’s Palace have to stockpile some Nine Heavens Immortal Spring so that I could leave here without any concern!”

After thinking about it for a short while, Tang Mei finally nodded as she said, “Well, elder brother, you’re right. But Emperor NvWa’s Palace doesn’t need too much Nine Heavens Immortal Spring!”

“Keep some Nine Heavens Immortal Palace for enabling at least 10 supreme immortal generals to promote to immortal emperors!”

“Okay!” Tang Mei said as she raised her hand towards the pond. Closely after that, a stream of water flew out of the pond and entered one of her portable finger rings.

After that, there were still more than 2/3 of Nine Heavens Immortal Spring left. When Zhang Tie wanted to teleport the Nine Heavens Immortal Spring and the colorful huge stone into Castle of Black Iron, he was stunned by Tang Mei’s words…

“Elder brother, don’t you want to take a look at the source of the conflict between humans and demons?”
