As night fell, under the starlight, Lin Feng walked into Li Yutong's back garden and saw the twenty square steel bars neatly arranged. He squatted down, picked up one of the square steel bars, and looked at it carefully.

"A square steel is two meters long, with a cross-section of almost four square decimeters. The mass of each square steel is about half a ton. The ten tons of steel here are twenty square steels. I don't know, this

How much refined 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 material among weapon-making materials. However, even in ancient times, it probably needed to be continuously smelted and purified in an iron ore before it could be made.

Get very little refined iron.

Now, of course, Lin Feng cannot go to some iron mines to mine for refining tools. He can only extract refined iron from these ready-made steel materials. However, Lin Feng does not know the iron content in these steel materials.

I don’t know how many kilograms of refined iron can be extracted from a meal of steel.

"Lin Feng, this is already the best quality square steel from our Lijia Steel Factory. See if it works. If not, I will think of a way for you." Li Yutong now also knows that Lin Feng is a legendary cultivator.

Moreover, many things cannot be inferred based on common sense. Anyway, she has 100% trust in Lin Feng and does everything according to Lin Feng's instructions.

"Sister Tongtong, there shouldn't be any problem with the quality of this steel. It's just that I don't know how much steel can be used to extract a pound of refined iron. Moreover, I'm afraid that the refined iron in the steel I refine and purify will cause a lot of noise. In your case

The garden is not suitable, so I have to go back to the alchemy room."

After Lin Feng thought about it for a moment, he said cautiously. Since he had never refined weapons before, he didn't know what would happen. To be on the safe side, it was better to go to the alchemy room.

"Ah? What should we do? Lin Feng, how about I call those workers to come back and move all these steel materials to the alchemy room? However, the alchemy room can't hold so many, at most five can be put in at a time.

Steel goes in.”

Hearing this, Li Yutong became a little worried. After all, each piece of steel weighed half a ton and required two to three workers to carry it. However, Lin Feng waved his hand with a smile and said to her

: "Sister Tongtong, there's no need. I can move this steel by myself. I'll put five of them in to refine them first. If they're not enough, I'll come out and move them."

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

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

Since his body was transformed by the twenty-four Dinghai Divine Pearls and Divine Water, Lin Feng has continuously strengthened his physical fitness through cultivation. Usually, some items weighing hundreds of kilograms are not stressful for him, and he can carry them around easily.

Walking as fast as flying. Therefore, Lin Feng also wanted to take this opportunity to see where the limits of his own strength were.

One piece of steel, two pieces of steel...

Lin Feng added one piece of steel one by one, while Li Yutong watched dumbfounded. Only two of those powerful porters could barely lift a piece of steel, but Lin Feng continued to add it by himself.

How strong is that? Li Yutong really couldn't imagine why Lin Feng's seemingly weak body could have such great strength.

One rod, two rods, three rods, Lin Feng felt quite relaxed. It was not until six rods were added that Lin Feng felt a little strenuous. After adding another seventh rod, Lin Feng felt that he could no longer support it, so he hurriedly

Withdraw the two steel rods and carry only five steel rods to the alchemy room on the first floor.

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

"

While carrying the five pieces of steel into the alchemy room, Lin Feng estimated his current strength, "I learned today through the Xiao family's intelligence network database that a warrior on the first level is about one hundred kilograms, and two hundred on the second level.

A pound of strength

, the third level is 300 kilograms of strength, but at the fourth level, which is the middle stage of the day after tomorrow, there is a leap in strength. The strength can increase to 600 kilograms, which is doubled. The crazy girl is the fourth level of the day after tomorrow, more than 600 kilograms.

strength."

Bang!

Lin Feng unloaded the steel materials one by one, and then used the strength level of a warrior to measure his current strength. "If you don't consider moves and martial arts, just look at strength. My current strength is about one ton, which is equivalent to two thousand kilograms of strength."

.The strength of the seventh level the day after tomorrow is one thousand kilograms, the eighth level the day after tomorrow is one thousand five hundred kilograms, and the ninth level the day after tomorrow is two thousand kilograms. In other words, my physical fitness is now equivalent to that of a ninth-level warrior the day after tomorrow."

In general, Lin Feng is very satisfied with his current physical fitness. With two thousand kilograms of strength, he can punch someone with all his strength, not only to kill him but also to cripple him. It can be seen from this that the last time he was at Qin Yanran's house

Zhao Shuang felt so uncomfortable after being kicked away by Lin Feng.

"Five pieces of steel, two and a half tons! Lin Feng, are you a strongman? You can carry such a heavy weight, it's amazing!" Li Yutong followed Lin Feng all the way in, and was really amazed by Lin Feng's huge strength.

Endless.

A man, with a field on top and a force on the bottom. It is a symbol of strength in itself. Lin Feng, who showed great strength, naturally fascinated Li Yutong even more.

"Take a rest! Lin Feng, I'll get you a bottle of Coke."

Li Yutong hurried to the refrigerator in the living room and brought Lin Feng a bottle of Coke. Seeing Lin Feng gulping down the Coke, she looked at him quietly and contentedly.

"Sister Tongtong! I am going to start refining these steels now. The temperature in the alchemy room may be too high and it is no longer safe."

After resting for a while and adjusting to his condition, Lin Feng planned to start refining the steel. Upon seeing this, Li Yutong nodded, exited the alchemy room and said: "Well! Lin Feng, be careful yourself. I'll be in the living room."

Watch TV, call me anytime if you need anything."

Even though Li Yutong looks like a strong female president of a club outside, in front of Lin Feng, she is a gentle and caring wife. As long as it is something Lin Feng tells her, she can always handle it properly, and

There is never a single complaint when I go there.

After Li Yutong exited the alchemy room, Lin Feng picked up a piece of steel and circulated the vitality in his body, stimulating the true vitality fire to refine the refined iron in the steel.

Sizzle...

The flames melted the steel bit by bit, but this speed was really not optimistic. A full hour passed, and Lin Feng felt mentally exhausted. A piece of steel was only half-refined.
