Unwilling to waste time and energy trapped in this very polluted place under his feet because of one or two chakra weapons, and unwilling to retreat without even seeing the face of chakra metal, Wu Liang thought about it again and again and took the opportunity of inviting the old merchant to eat lunch, and relied on pouring wine to get out of his mouth only a little basic information about chakra metal, although the old merchant did not have the strength to participate in this kind of competition at the level of the country and the ninja village, but because he was old enough, he had seen the finished chakra metal many times. Even the appearance of the raw mine.

If there is not too much touting ingredient, then according to him, the so-called chakra metal ingot is not much different from ordinary black iron ingots from the appearance, but the volume is nearly half smaller under the same weight, and there will be a faint star-like reflection when swept in the dark place, and judging the amount of chakra metal content in the metal ingot can only be judged by the naked eye from the reflective color, and there will definitely be a very big error if it is not an experienced professional.

As for whether there is a more accurate identification method for the top level of the Iron Country, it is unknown to outsiders.

Compared with the finished metal ingots that are difficult to judge from the naked eye, the raw ore ore of Chakra metal is more characteristic and easier to identify, and unlike the common metal ore, the texture is hard and ultra-high density Chakra metal ore raw ore is like a quartz crystal (that is, we often say natural crystal) is a crystalline accompanied by a very small number of high-quality composite metal ores, and the specific reason for its formation is completely unclear.

Thanks to its hard texture, most of the raw ore obtained by conventional mining methods is intact, and it can still maintain its original shape from the unique shape and weight, and even its high temperature enough to melt steel. Even the five ninja villages failed to succeed as they wished, which shows how high the level of secrecy is.

It is said that forty or fifty years ago, when the special smelting method and the characteristics of chakra metal were not discovered, these unique shapes and conventional smelting methods were helpless, and the chakra metal ore was basically treated as useless slag at will, and even some miners who had a good relationship with the foreman took it home to the child as a toy after greeting him, and when the child grew up, he found that the toy had become a precious and abnormal treasure. Therefore, the rumors of getting rich overnight or being wiped out and dying were once rampant in the land of iron, and many ancestors were miners, and they also deliberately dug three feet near their ancestral homes to search, and really found a number of old mines that were shiny and shiny, so that many people got rid of the poor life!

Of course, these rumors are stories from a long time ago, and it is said that it has been almost a decade since a merchant bought this precious legacy from the miners, and it is better to put your hope on such false rumors than to be a digger like the treasure hunters who have been abandoned many years ago near the old mines. At least recently, I heard that there are lucky guys who dug up the raw ore that was disposed of as slag many years ago when they planted sweet potatoes on the pit that collapsed by the flood.

But the time spent in this way is really uncountable, there are still four followers left and the quota has not yet been selected, Wu Liangke has never intended to spend all his time in a place with a bad environment like the Iron Country, instead of temporarily finding four samurai to make do, it is better to include the cockroach uncle and nephew in the follower candidate list!

At least after spending a long time with each other, they don't feel how awkward it will be to have each other in their daily lives.

-----------------------------------------------------------------

Although I don't have much interest in wasting too much time in the Iron Country, I might as well go to see the auction that is about to start, and I have to start playing with the chakra metal that is regarded as a treasure by many people to be worth the ticket price, otherwise it will be worth the trip.

Under the hospitality of good wine and good food, the old businessman did not have any hypocrisy, and very readily agreed to take Wu Liang and his followers to a long experience, if there is really a finished chakra metal ingot for sale this year, you might as well join in the fun, if it exceeds the psychological expectation too much, it is a big deal not to continue bidding.

Wu Liang, who had made up his mind to get in touch with the real thing, went to the capital of the land of ---- Iron Country with the small caravan of the old merchant in the afternoon of the same day!

The deeper you go into the border of the Iron Country, it is not difficult to find that the environmental pollution is getting more and more serious, even if you wear a mask, it is difficult to adapt to the increasingly thick smell of soot, and you want to take out a gas mask and worry that it will be too weird and attract interrogation, which is really nostalgic for the cold winter wind of the past few days, even if the wind is a little cold, it is better than being smoked by soot.

After more than ten hours, through a large circle of mines and smelters, I finally came to the capital in the heart of the Iron Country, and I felt better after entering the city and putting on breathing masks for all the people and horses, and then under the close watchful eye of a group of guards, I went through the procedures for entering the city with a little numbness, and stayed in a large hotel where the traveling merchants were uniformly placed, and only after a day of groggy rest can I feel refreshed.

With the help of the old merchant's connections, Wu Liang hurriedly paid a deposit of one million taels of banknotes before the auction began, and soon obtained a small wooden plaque representing the right to bid, and entered the spacious and grand auction hall with his followers, and followed the arrow on the sign to the central auction hall located on the second floor of the auction hall, and finally had the opportunity to witness the highlight of today's auction after spending 50,000 taels to open a medium-sized box---- a strip about 25 centimeters long, 10 centimeters wide, and 5 centimeters thick. Chakra metal ingots are solemnly placed on a cushion with light blue velvet!

Of course, because it came relatively late, and it did not represent any large forces, so it was impossible to get any good position simply by spending money, and the location of this medium-sized box opened by Wu Liang was far and remote, and if you wanted to see the true appearance of the chakra metal ingot, in addition to mobilizing your eyesight, you also had to use the indispensable props of the telescope.
