This time to advance the nine changes of the earth, Zhang Tie consumed the three demon earth knights he captured all the way from the Xiangshan County escort airship brigade, because the strength of these three demon earth knights is uneven, not the top, after secretly refining the water chakra of the three demon earth knights with purgatory reincarnation, Zhang Tie also consumed more than 800 water yuan crystals to condense his water chakra to 324 scales.
Zhang Tie quietly completed this advance in the hotel's apartment.
After sitting cross-legged on the bed in the bedroom all night, Zhang Tie got out of bed after advancement, moved his muscles and bones, and then calmly went to the bathroom to wash.
Unscrewed the faucet in the bathroom and washed his face, Zhang Tie raised his head, and what appeared in the mirror was the face of a Chinese man in his forties, with water droplets on his face and sharp eyes, this face is what Zhang Tie looked like after he disguised himself with the phantom vein, and he has been using this face to move in Tiangong City for the past two months, and his current name is Iron Longbow.
Because Zhang Tie had never shown his attainments in rune refining before, no one in the entire Tiangong City would recognize this person as Zhang Tie by seeing the name Iron Longbow from behind to before.
There are too many rune refiners in Tiangong City, in addition to Taixia's, there are also many rune refiners from other subcontinents gathered here, and fresh faces arrive almost every day, and some old faces leave, so Zhang Tie's current face is not any problem.
"The earth has changed nine times, do you still want to stay in Tiangong City" Zhang Tie muttered to himself in the mirror, and then shook his head.
The Nine Changes of the Advanced Earth did not bring too many surprises to Zhang Tie, and after staying in Tiangong City for two months, Zhang Tie also knew how difficult it was for him to realize his idea.
In the past few hundred years, in Tiangong City, Zhang Tie was not the first rune refiner who wanted to create a weapon that could kill knights, but in these hundreds of years, no one had ever succeeded, compared to the cultivation path of condensing the chakra, this seemed to be a more difficult, steeper, and more difficult path to climb.
In the realm of the Soul Tribulation in Xuanyuan Hill, Zhang Tie checked the confidential information of the headquarters of the various trade unions of the Terran in the past two months, only to find that not only himself, but even the entire Taixia and the Seven Great Sects were conducting secret research in this area, and the weapons and means that could kill the knights had become one of the highest secret issues of the Terran Rune Refiner Union, the Alchemist Union, the Pill Medicine Master Union, and the Beast Master Union for hundreds of years.
The alchemists want to invent a more powerful alchemy bomb that can kill knights under normal circumstances, the elixir master union is developing a terrifying voodoo that can kill knights, and the beast master union is cultivating some strange things that can devour knights, all of which are carried out in the name of fighting demons, but whether the top professionals of the various guilds behind it have the idea of pulling knights down from the throne of the human ruler, no one knows.
The reason why alchemists are good is because among all the non-knight professions, so far, only the alchemy bomb made by the alchemist can kill the black iron knight in some specific environments, and at the level of the earth knight, it is difficult to be killed by the alchemy bomb, and the research results of other guilds have not reached such a height.
If any profession can really invent something that can kill knights, then there is no doubt that that person will become the well-deserved king of that profession, but so far, such a king has not really appeared.
In the face of such a difficult challenge, even Edward in the Black Iron Castle has no way to provide more help to himself, everything can only rely on himself, Edward's rune refining level has reached the level of rune refining grandmaster, one level higher than Zhang Tie, a master craftsman, Edward can create what he specifies, but Edward cannot carry out groundbreaking research and invention, all his knowledge and skills are fixed.
Zhang Tie's confidence did not waver, but during this time in Tiangong City, he saw clearly what the difficult challenge he was about to face was, what was in front of him was a high mountain, and no one could reach the top of the mountain from the foot of the mountain in one step.
After washing up in the room, Zhang Tie tidied up and left the apartment, before going out, he also entered and exited the Black Iron Fort with lightning speed, ate the redemption fruit of a golden unicorn fairy, moved his mouth, and opened the door of the apartment.
This apartment is a hotel called Steam World in Tiangong City, there are many hotels in Tiangong City that are specially prepared for rune alchemists, and the hotel that Zhang Tie chose is not the best, nor is it the worst, it is of medium grade, just like Zhang Tie's current identity and appearance, it is not noticeable at all.
Tiangong City is built on the largest mining area in Bingzhou, so the most common thing in Tiangong City is metal, if anyone wants to mine, just find a hoe, dig a few meters underground in any place in Tiangong City, you can see high-quality manganese iron ore.
When Zhang Tie walked out of the door of the hotel, the time had already reached the afternoon, and the entire Tiangong City was busy.
In other Grade A cities in Taixia, Zhang Tie has rarely seen that kind of chimney forest, but in Tiangong City, such a situation is very common, the entire Tiangong City, almost surrounded by countless large and small chimneys, the black smoke coming out of the chimneys makes the blue in the sky of the entire Tiangong City blurred, just as soon as he walked out of the hotel, Zhang Tie smelled the faint smell of coal tar lingering in the air.
From the point of view of environmental protection, Tiangong City is a city with serious industrial pollution, no matter which era, the roar of steel and machines can not always be compatible with the green mountains and green waters, but the people in Tiangong City, no one cares about this, and even the smoke in the sky of Tiangong City is covered by blue and non-blue colors, in Bingzhou, there is a special name Tiangong Blue.
Among the cities that Zhang Tie has seen, the only city with the temperament of Tiangong City is Kaluer, the machine city on the Weiyi subcontinent, if Karur can be ten times more prosperous, and the area will be expanded by a hundred times, it will be almost the same as Tiangong City.
With the advent of the Holy War, especially last year's demon invasion of Taixia, the orders and output of the war castles and factories of various steam weapons produced in Tiangong City ushered in an explosive growth, and countless giant airships rose and fell in the sky of Tiangong City, and the products produced in Tiangong City were being transported in all directions.
Zhang Tie glanced up at the sky, and then like pedestrians coming and going on the road, he pulled up the dust mask on his hood to cover his small half of his face, and after leaving the hotel fifty meters, he jumped on a free tram that had just crossed the road outside the hotel, and drove towards the Dongcheng District of Tiangong City More than ten minutes later, after transferring to two tram cars, Zhang Tie got off the car, and after walking through the streets and alleys of Tiangong City for a few minutes, he came to the door of a building composed entirely of steel and had a strange and complex geometric shape, and the signboard above the door.
There was no sign in this building, and there was no post at the door, and in front of Zhang Tie was only a thick iron door that was tightly sealed, and a special device for the lock position on the outside of the iron door.
Zhang Tie took out a gold coin, and stuffed it into the gap of the device at the lock position that could just be stuffed into a gold coin, and then with a movement of mental power, he directly used his fingers to write an ordinary rune symbol of solidification on a Mithril rune writing board next to the position of the gold coin, and under the effect of the gold coin and the rune, this thick iron door slowly and automatically opened, allowing Zhang Tie to flash into it.
Here, it is a place where rune refiners gather in Tiangong City, and the entrance fee for each entry into it is a gold coin, and it must reach the level of a secret rune master, and "show a hand" on the Mithril rune writing board at the door, and the door will automatically open, not to mention anything else, just the iron door here that must be opened with a gold coin and a rune, is a high-level rune refining equipment.
Behind the door was an aisle, and two big men stood behind the door, making sure that only one person came in, and after passing through that aisle, Zhang Tie entered a bar.
Even during the day, there are already a lot of people gathered in this bar, and everyone is sitting and talking together.
As soon as Zhang Tie came in, two people at a table in this bar beckoned to Zhang Tie.
Zhang Tie pulled off the dust mask on his hood, walked over directly, pulled out a chair on the side of the table, and sat down.
Sitting at the edge of the table were two Chinese rune refiners, each of whom looked to be in their fifties, one was tall and muscular with a beard and hair that had grown almost together, while the other man with glasses looked more delicate.
"Lao Tie, you're late today, I thought you weren't coming," the rune refiner with an unkempt physique said with a big grin.
"Today I lit a bright spot again, so I came a little late" Zhang Tie said calmly, took the wine bottle on the table with his own hands, and poured himself a glass of lemon wine Most rune refiners don't like alcohol, because alcohol will dull people's brains and cause mental fluctuations, and drinking for a long time will even make people fall with hand tremors, which is a big taboo for rune refiners, although the limoncello in this bar is said to be wine, but the alcohol content is very low, just like the taste of soda and lady's champagne, This is also the most common drink for rune refiners who come here.
"Hahaha, do you still want to advance to the knight, if there is such a day, when you turn the wheel ceremony, I will definitely give you a big gift" The rugged rune refiner laughed, and slapped Zhang Tie on the shoulder twice.
Of course, this is a joke, because Zhang Tie's current identity role of the Iron Longbow, so far, is only a tenth-level strong warrior who has just mastered the skill of exerting battle qi, which is also in line with the strength level of most rune refiners, a group of people who have the talent of rune refiners and devote most of their time to this field and can achieve extraordinary achievements, rarely can make a big breakthrough in cultivation, all rune refiners who can advance to the level of secret rune craftsmen and above, More than 99 percent of them, throughout their lives, the possibility of becoming a knight is very slim, this is the objective law of the development and growth of things, just like a great athlete and an accomplished pianist are difficult to be the same person, a qualified person even if he works hard, it is great to be able to achieve something in one field in his life, and those who can achieve something in more than two fields are absolutely rare.
The reason why Demon Alchemy Zhao Yuan is good is precisely because he is not only a super bull alchemist, but also a strong Sky Knight, and people like Demon Alchemy Zhao Yuan can't find a few in the entire Taixia.
Zhang Tie is also very good, he is not only a knight, but also a rune refiner, or a strong beast master, but Zhang Tie's ox is based on the Fruit of Plunder generated by the Black Iron Castle and the small tree, if there is no Fruit of Plunder, Zhang Tie wants to reach his current attainment in the realm of rune refiner, it can only be a dream.
The two rune refiners sitting at this table with Zhang Tie are the new friends Zhang Tie has met in Tiangong City in the past two months, both of them are master craftsmen, and the rune refiner with unkempt physique is called Lin Xiuxian, who is one of the head snakes in Tiangong City, this guy has been in Tiangong City for more than fifty years, according to his words, there is nothing in the entire Tiangong City that he can't do.
Another somewhat delicate and Sven rune refiner is called Zhu Daqian, Zhu Daqian was born in a wealthy family in Taixia, according to his words, the reason why he came to Tiangong City was completely sent to Tiangong City by his family with high hopes and waited for him to go back to the family after advancing to the "Craftsman Sect" one day, at the beginning, Zhang Tie also believed it, but once, Zhu Daqian himself drank lemon wine and got drunk and said that he leaked his mouth, Zhang Tie knew that this guy was sent to Tiangong City because of a woman who was kicked out of the house by the patriarch at home.
A person can get drunk by drinking some lemoncell, the key is that this person also took a heroic name called Zhu Daqian, Zhang Tie was also speechless, and every time he saw Lin Xiuxian, who often didn't take a shower for a week or two, and Zhu Daqian, who insisted on changing a set of clothes every day and even wore a dust mask that was processed and treated with dust cleaning runes, Zhang Tie felt that these two people had taken the wrong name, and if the names of these two people were exchanged, it was estimated that it would be more compatible.
"Did you bring what I wanted" Zhang Tie said, and his eyes turned to a half-meter-long lead bucket beside Lin Xiuxian:
