Chapter 669： Is this too **** difficult?

Little ÷ Say ◎ Net], ♂ Little ÷ Say ◎ Net],

As night fell, under a little bit of starlight, Lin Feng walked into Li Yutong's back garden and saw the twenty square steels neatly laid out. He squatted down, picked up one of the square steels, and looked carefully.

"A square steel is two meters long, and the cross section is almost four square decimeters. The mass of each square steel is exactly half a ton. Ten tons of steel here is 20 square steels. I don’t know, this How much fine iron can be extracted from a piece of square steel."

The material used by Lin Feng to refine the flying sword is refined iron, which can be said to be the lowest grade among the refining materials. However, even in ancient times, I am afraid that it would require continuous smelting and purification in an iron ore to obtain very few refined iron.

Now Lin Feng, of course, can't go to some iron ore mines, and can only extract refined iron from these ready-made steels. However, Lin Feng didn't know what the iron content in these steels was, or how many catties of fine iron could be extracted from a single meal of steel.

"Lin Feng, this is already the best quality square steel in our Li's steel mill. You can see if it works, if it doesn't work, I'll find a way for you." Li Yutong now also knows that Lin Feng is the legendary cultivation. However, many things cannot be inferred by common sense, anyway, she trusts Lin Feng 100%, and everything is done according to Lin Feng's instructions.

"Sister Tongtong, there should be no problem with the quality of this steel, that is, I don’t know how much steel can produce a pound of refined iron. Moreover, I’m afraid the movement of refined iron in the refined steel will be relatively large. The garden is not suitable, we still have to go back to the alchemy room."

After thinking about it for a moment, Lin Feng said cautiously. Because he has never refining an instrument himself, he does not know what will happen, so it is better to go to the alchemy room to be on the safe side.

"Ah? What can I do then? Lin Feng, should I call the workers back and move all the steel to the alchemy room? However, the alchemy room can't fit so many, at most five at once. The steel goes in."

Upon hearing this, Li Yutong became a little worried. After all, each of these steels weighs half a ton and requires two to three workers to be able to handle it. However, Lin Feng smiled and waved his hand, and said to her, "Sister Tongtong, it's not necessary. I can move this steel by myself. I will put five wires in it for refining. If it is not enough, I will Come out and move."

"A piece of steel weighs half a ton? Lin Feng, can you really do it alone?" Li Yutong couldn't help but worry.

Without a word, Lin Feng grabbed a piece of steel on the ground with both hands. After weighing it a few times, he smiled and said, "It's quite heavy! But I can still hold a few more."

Since being transformed by the 24 Dinghai God Pearls and Shenshui, Lin Feng has continuously strengthened his physical fitness through cultivation. Usually some hundreds of catties of things are not stressful for him, and he can walk as fast as he can. Therefore, Lin Feng also wanted to take this opportunity to see where the limits of his strength were.

One steel, two steel...

Lin Feng added one by one, Li Yutong was stunned. Those Kong Wu's powerful porters could barely lift a piece of steel by two people, but Lin Feng continued to increase it all by himself. How much strength is this? Li Yutong couldn't imagine why Lin Feng's body, which didn't seem to be strong, would have so much strength.

One, two, three, Lin Feng felt quite relaxed. Lin Feng didn't feel a little struggling until after adding six steels. After adding a seventh rod to the top, Lin Feng felt that he couldn't hold it anymore. He quickly removed the two steel rods and carried only five steel rods to the alchemy room on the first floor.

"Sure enough! My current physical fitness has been greatly improved, and I can almost afford three tons of items. The strength under a punch should be one-third of the load, which is almost a ton of strength. "

While carrying five steel bars into the alchemy room, Lin Feng estimated his current strength, "Today, I learned from the Xiao family's intelligence network database that the martial artist on the first floor is about one hundred kilograms of force, and the second floor is two hundred. Jin strength, the third floor is three hundred Jin strength, but to the fourth floor, it is the middle of the day after tomorrow, there is a leap in strength, the strength can increase to six hundred Jin in one go, directly doubled. The crazy girl is the fourth floor after the day, six hundred How much strength."

boom!

Lin Feng unloaded the steel one by one, and then used the strength of the martial artist to measure his current strength. "If you don't consider the moves and martial arts, it's pure strength. My current strength is about one ton, which is equivalent to two thousand catties. The 7th floor of the acquired day has a strength of one thousand catties, the eighth floor of the acquired day is 1,500 catties, and the ninth floor of the acquired day is two thousand catties. In other words, I am now equivalent to the physical fitness of a martial artist on the 9th floor of the acquired day."

In general, Lin Feng is still very satisfied with his current physical fitness. With a force of two thousand catties, he went out with one fist and beat people to death. This shows how uncomfortable Zhao Shuang who was kicked by Lin Feng at Qin Yanran's house last time.

"Five rods of steel, two and a half tons! Lin Feng, are you a Hercules? You can move in so heavy, too powerful!" Li Yutong followed Lin Feng all the way in, really amazed by Lin Feng's tremendous strength Endless.

Man, there is a field above and a force below. Lin Feng, who is a symbol of strength in itself, is naturally fascinated by Li Yutong even more.

"Take a break! Lin Feng, I'll get you a Coke."

Li Yutong hurried to the refrigerator in the living room and brought Lin Feng a Coke. Seeing Lin Feng gulping his coke, he looked at him quietly and contentedly.

"Sister Tongtong! I'm going to start refining these steel now The temperature in the alchemy room may be relatively high and it is not safe."

After resting for a while and adjusting the state, Lin Feng planned to start refining the steel. Seeing this, Li Yutong nodded and exited the alchemy room and said, "Well! Lin Feng, you should be more careful yourself. I will watch TV in the living room and call me whenever you have anything to do."

Regardless of Li Yutong’s appearance as a powerful female president of the club, in front of Lin Feng, she is a gentle and caring internal helper. As long as Lin Feng confessed, she can always do it properly. There will never be a complaint.

After Li Yutong withdrew from the alchemy room, Lin Feng picked up a piece of steel to circulate the vitality in his body, inspiring vitality and real fire to refine the fine iron in the steel.

Zi Zi Zi...

The flame melted the steel little by little, but at this speed, it was really not optimistic. After an entire hour passed, Lin Feng felt that his spirit was a little tired, and a piece of steel was only half refined.

"Isn't it? It takes only an hour to refine half of the steel. Isn't this too **** difficult?" Lin Feng took a few breaths and couldn't help feeling.
