Castle of Black Iron

It was absolutely an accident that Wu Qingkun realized the medicament that Zhang Tie gifted him was something great.

Wu Qiankun had put Zhang Tie's gift in his home at Dragon Emperor's City for a few months. He didn't find its medicinal value until Wu Qiankun's servants had an accident two days ago.

As the general manager of Emperor NvWa Palace, Wu Qiankun was obsessed with the delicacy in Dragon Emperor City despite being an outsider.

A bizarre, tender, fresh and tasteful snowflake bamboo shoot would appear deep in the mountains outside Dragon Emperor City in every winter. They were available only for a short period of time in winter. Wu Qiankun loved them the most. However, snowflake bamboo shoots were rare. Additionally, it could only be preserved for only half a day. If it was not eaten in half a day after being dug out of the earth, it would turn soft like a snowflake and lose its fresh taste.

Therefore, in each winter, the servants of Wu Qiankun would go to the woods outside Dragon Emperor City under the leadership of his butler to dig snowflake bamboo shoots for him.

Two days ago, when some servants of Wu Qiankun entered the woods outside Dragon Emperor City to dig out snowflake bamboo shoots, they encountered an accident——when those servants were digging out the bamboo shoots, they met a rare wind snake. In a split second, 7 of them were attacked and poisoned.

The venom of wind snake was hypertoxic. If a commoner was bitten by it and couldn't get timely treatment, he would die in a few hours. None of the people below immortal generals could survive its venom. Even if a wind immortal general was bitten by a wind snake, he or she would also lose a lot of vitality before gradual recovery.

There was an antidote for the venom of wind snake, the most important raw material of which was the gall bladder of wind snake. However, as wind snake moved as fast as a lightning bolt and was rare in quantity, this kind of antidote was always in urgent need.

When Wu Qiankun's servants were sent back into his home, Wu Qiankun, after being noticed, instantly got three antidotes and saved three people. As for the rest four, they were not that fortunate anymore.

It was already difficult for Wu Qiankun to find three antidotes in such a short period of time as the general manager of Emperor NvWa Palace. Who could imagine that the servants of Wu Clan were so unfortunate that 7 of the group of 10-odd people were poisoned by a wind snake in the blink of an eye when they went to dig snowflake bamboo shoots in the woods. Therefore, 3 antidotes were far from enough.

At that time, Wu Qiankun could only arrange the rest 4 victims to stay in the pools of recovery so as to delay the effect of the venom of wind snake for the time being. After that, he hurriedly asked others to find the antidotes. Finally, he got enough antidotes; however, they were not in Dragon Emperor City. Even if he had people transport them by airboat, it would also take him at least one day. Nevertheless, the victims could at most stand a few more hours in the pools of recovery.

When Wu Qiankun was in despair, he suddenly recalled those medicaments that Zhang Tie gifted him.

He also recalled what Zhang Tie told him in the imperial palace, "As long as you feel uncomfortable physically or spiritually, you could use it". Of course being poisoned made people feel uncomfortable. Therefore, Wu Qiankun took out the medicament that Zhang Tie gifted him and distributed one vial of all-purpose medicament to each of the four servants.

Wu Qiankun didn't imagine that Zhang Tie's gift could detoxify the venom of wind snake. Therefore, the result made him dumbfounded.

Soon after the four servants took the medicament, the venom had been detoxified. The effective speed of the medicament could even match the professional antidote. As a result, before the antidotes arrived at Dragon Emperor City, all the four servants of Wu Qiankun had been as safe and sound as before.

Not until then did Wu Qiankun know the exceptional effect of those medicaments.

Had Zhang Tie predicted that Wu Qiankun needed the antidotes to the venom of wind snake? If not, why did he gift those medicaments to him? Were those medicaments especially effective to the venom of wind snake?

Of course, Wu Qiankun didn't believe that Zhang Tie could predict all these. Even if Zhang Tie was proficient in fortune telling, as Dragon Emperor, he would not be bored enough to care about the lives of Wu Qiankun's servants. Therefore, the most reasonable explanation was that it was only one of its effects to detoxify the venom of wind snake.

These couple of days, Wu Qiankun was testing the effects of those medicaments that Zhang Tie gifted him.

In the beginning, he found some poisons which were as poisonous as the venom of wind snake and made experiments on animals. The result made Wu Qiankun widely open his eyes. Those poisons which didn't even have antidotes were all successfully detoxified by the medicament that Zhang Tie gifted him.

Besides, Wu Qiankun even made experiments on his servants and himself for a few times. He found that those medicaments could not only help people recover their spirit and physical strength fast but also cure people's internal and external injuries remarkably; especially the latter effect, which could even match that of the preliminary pool of recovery.

What did this recovery mean to immortal generals? It meant that immortal generals could take such a vial of medicament with them just like taking a preliminary pool of recovery. With them, they could recover their injuries in the shortest period of time. Actually, over 99% of immortal generals in Motian Realm couldn't take a portable space-teleportation equipment with a pool of recovery inside. If it was in wartime, people's lives would be greatly guaranteed by carrying such vials of medicament.

Wu Qiankun was completely shocked by the effects of Zhang Tie's gift. Before this, Wu Qiankun had never thought about the existence of such marvelous medicament in Motian Realm.

After discovering the effects of those medicaments, Wu Qiankun even didn't grudge making experiments with those medicaments.

After discovering the exceptional effects of Zhang Tie's medicament and their potential in the market, Wu Qiankun couldn't wait to go to the Dragon Emperor Immortal Palace to purchase some more in case of emergencies. No immortal generals would complain about taking too many such vials of medicament.

When Wu Qiankun described what happened, Zhang Tie just listened to him extremely patiently with a smile.

Zhang Tie found that he had underestimated the shock and surprise that his all-purpose medicament could bring to the immortal generals of Motian Realm. Previously, Zhang Tie thought that Wu Qiankun would invite a professor to study his medicament. After figuring out all the effects of his all-purpose medicament, he would take the powers of Emperor NvWa Palace here to negotiate with Zhang Tie about the trade. Unimaginably, only after discovering a part of its effects, Wu Qiankun had already come for him impatiently.

"If not for the accident in my mansion, I wouldn't have known that Your Majesty had gifted me such precious medicament!" Wu Qiankun sighed with mood as he added, "I've never heard about such a marvelous medicament. I'm really stupid. I almost treated it as a common medicament and made a fool of myself. Oh, Your Majesty, what do you call it?"

"It's Dragon Emperor's Medicament!" Zhang Tie answered solemnly.

As pharmacists in Motian Realm were not popular; nor had people heard about all-purpose medicament. If Zhang Tie told Wu Qiankun it was called all-purpose medicament, Wu Qiankun must be muddle-headed about that. Therefore, Zhang Tie preferred to give the wholly new all-purpose medicament a grand and dignified name which might bring him more element crystals in the future. In Donder's words, the name was brand. On many occasions, a commodity with a good name or a well-known brand had already succeeded half before being pushed into the market. A good name could bring him much more benefit. The name Dragon Emperor's Medicament sounded grand and impressive. In the near future, it could definitely become the golden brand in Motian Realm.

"Dragon Emperor's Medicament...Dragon Emperor's Medicament..." Wu Qiankun smacked his lips as he nodded forcefully, saying, "Right, only this name could match its marvelous effects!" Wu Qiankun commented as he took a meticulous look at Zhang Tie again, asking, "I wonder who invented it..."

"I invented it..." Zhang Tie replied frankly, which was actually the truest words that Zhang Tie said today.

As was imagined by Zhang Tie, the moment Wu Qiankun heard that Zhang Tie was the inventor, he instantly admired Zhang Tie as he spoke highly of him, "Your Majesty, you're really a genius. No wonder the Grand Dragon Emperor would like to you to take his throne!"

"Thanks. As the old man always drank my medicament, I named it after I became the disciple of the old man and knew his real identity!" Zhang Tie started to talk nonsense. However, on this occasion, Wu Qiankun would be deeply convinced by Zhang Tie no matter what the latter said. Nothing was more convincing than the effects of Dragon Emperor's Medicament.

That got to be Zhang Tie. Each lie or plan of Zhang Tie was based on some real convincing things. Therefore, Zhang Tie could easily allure everyone into his trap.

"I've got two purposes here. First, I have to extend my thanks to Your Majesty. Without the medicament that Your Majesty gifted me, some of my loyal servants would have died of my greedy appetite. It would be against my conscience. I would feel guilty about it for a long time. Second, I want to know whether Your Majesty has more Dragon Emperor's Medicament. If there are, I prepare to ask for some more from Your Majesty in case of emergencies. Emperor NvWa Palace's disciples were always bitten by poisonous beasts across Dragon Emperor's Big Domain. As we couldn't find the corresponding antidotes in a short period of time, we couldn't avoid tragedies. If I got some more such medicament, I might be able to save more people so as to fulfill my responsibility as the general manager of Emperor NvWa Palace..." Wu Qiankun started to show his eloquence, "I know the medicament is of a high price. However, I shouldn't buy them from Your Majesty given your dignity. But, I want some more from Your Majesty shamelessly. Hopefully, you could forgive me, Your Majesty!"

"Hahaha, now that General Manager Wu is so straightforward, if I don't give them to you, I would be the mean guy!" Zhang Tie said as he burst into laughter, "How about giving you 200 vials of Dragon Emperor's Medicament..."

After hearing that, Wu Qiankun became so thrilled as he hurriedly appreciated Zhang Tie by bowing down deeply, "Thanks, Your Majesty. Thanks, Your Majesty!"

"However, I've got one condition!"

"Go ahead, please." Wu Qiankun became stunned for a second as he asked.

"General Manager Wu should send 100 of the 200 vials of Dragon Emperor's Medicament to Emperor NvWa Palace and have powers or pharmacists in Emperor NvWa Palace authenticate its effects. By the way, General Manager Wu needs to tell the powers of Emperor NvWa Palace that I could realize mass-production of Dragon Emperor's Medicament. I wonder whether Emperor NvWa Palace is interested in Dragon Emperor's Medicament or not!" Zhang Tie put it straightforwardly instead of wasting time anymore.

"What? Mass Production?" Wu Qiankun raised his pitch at once with an unimaginable look as if he had misheard it or thought that Zhang Tie was kidding with him. The two words "mass production" made Wu Qiankun feel like that element crystals could be grown in the ground. That was amazing!

"I mean it. General Manager Wu only needs to bring my words to them. I will be responsible for all the results!" Zhang Tie confirmed with a smile, "As for what happened in Motian Realm today, General Manager Wu might be able to know some intelligence from Emperor NvWa Palace. I have to enter secluded cultivation in no time. I hope General Manager Wu could come here with the gods of Star Emperor Immortal Palace next time!"

After saying those words, Zhang Tie took his teacup and lightly blew on it...

...

Wu Qiankun left Yangxin Palace and Forbidden City with two wooden boxes, each of which contained 100 vials of Dragon Emperor's Medicament.

Zhang Tie didn't know how Wu Qiankun felt when he left Yangxin Palace; however, Zhang Tie felt pretty good when he left Yangxin Palace.

Outside Yangxin Palace, Zhang Tie looked up at the sky as he found that the cyan flowing flames in the sky had not completely disappeared yet. The entire sky was slowly changing its color like porcelain being taken out of the kiln.

The intense atmosphere across Forbidden City had not faded away yet. However, the uproar aroused by the abnormal phenomenon in the sky had just come to a start.

Under the respectful eyes of Leng Manxue, Zhang Tie returned to his backroom in Jiaotai Palace and continued to cultivate.

"This substitute is really helpful to me. Zhang Tie, you're too smart! Hahaha..." Zhang Tie lowered his head and watched himself as he revealed an obscene smile. Closely after that, he closed his eyes.

Not until then did the original body of Zhang Tie open his eyes in Castle of Black Iron with the same obscene smile.

"Congratulations, Castle Lord, you've promoted to a heavenly knight..."

The moment Zhang Tie opened his eyes, he instantly heard these words...

'I finally became a heavenly knight...' Zhang Tie sighed with mood.
