To put it bluntly, this cutter is a large drill bit. Although it is not a top-grade magic weapon, the manufacturing process is very tried. The material used is mica diamond with extremely high hardness. This kind of diamond is not only hard, but also not easy to break. It is very difficult to process. Most refiners have no choice.


    However, this is Baoxia Island, where the art of refining utensils was developed. There are many skilled craftsmen.


    Taking the mountain cutter, Su Chen went to the nearby area to practice while Gao Meng and them were exploring the way.


    It seems easy to use this mountain cutter, but the control of power, speed and angle needs to be very accurate. If there is yuan force to assist the control, it will be no problem, but Su Chen has only brute force now.


    You''d better be careful, or you''ll be embarrassed if you break this mountain cutter.


    Fortunately, Su Chen''s savvy is OK. After several attempts, Su Chen is probably proficient in the use of mountain cutter.


    Not to mention, if this weapon is used smoothly, its power is very good.


    If Su Chen recovers his strength, he wants to make a magic weapon similar to the mountain cutter. This thing must be very lethal. If he hits it, he can directly hang a big hole in the enemy.


    The trick of using the cutter is to twist the cutter at the same time when the output is made, so that the reamer can smoothly cut into the rock, and push the rock fragments out of the wide and thick gap in the cutter through inertia, which is almost the same as the principle of electric drill.


    Just then, a miner surfaced and handed a rope to Su Chen: "little brother, the position has been explored."


    "OK."


    Su Chen held up the mountain cutter and touched the rope to dive directly into the water. The turbulent current immediately came to him.


    Su Chen''s clothes were instantly soaked in the sea water.


    This feeling is still a little wonderful for Su Chen.


    After all, when he went into the water in the past, he had yuan force protection on his body and would not get wet at all. The resistance of water would not have any impact on him, but now he has no yuan force protection. When he moves underwater, he is obviously hindered a lot.


    However, this obstacle does not pose a threat to Su Chen.


    He followed the deep lock and came to the designated place smoothly.


    Su Chen punched on the rock wall.


    It made a big gap, but the destructive power was not as amazing as Su Chen imagined.


    That''s right. Without the blessing of vitality, the destructive power is very limited only by the brute force of the flesh. At most, it is the level of the pile driver. However, if vitality is added, it will cause the effect of space shock explosion, and the destructive power is the explosion level.


    The road of physical cultivation is really hard to walk. You still have to recover your strength as soon as possible.


    Seizing the mountain cutter, Su Chen pushed forward with rotating force and began to dig the hole.


    I thought it was a very simple thing, but under the water and the momentum of the ocean current, Su Chen''s body could not maintain stability at all, and his power was difficult to give full play to the accuracy, which made the efficiency of opening a hole much slower.


    He has to open a 200 meter passage to the north to unload the sea water.


    Moreover, the hole should not be too small. Otherwise, the speed of sea water circulation will be very slow. Maybe he needs to open more channels.


    "We have to hurry!"


    Su Chen can''t hold his breath underwater for too long now. It''s estimated that half an hour is the limit. He should grasp it every minute.


    At full speed, the mountain cutter broke out a buzzing in Su Chen''s hands. Su Chen''s hands skillfully controlled the mountain cutter and kept the mountain cutter rotating at a high frequency. Maybe it was the reason why it was on the right track, and the subsequent cutting speed was accelerated a lot.


    The distance of 200 meters was shorter than Su Chen thought. About seven or eight minutes later, Su Chen opened a channel, and a large amount of sea water immediately poured into a huge empty mine.


    The mine is so deep that all the sea water can be poured in.


    Su Chen took a few breaths and began to open a hole in the opposite direction.


    In this way, the six large holes discharged flood at the same time, and the water pattern in the pit began to decline at a speed visible to the naked eye.


    It seems that Gao Meng has blocked the gap.


    Su Chen surfaced and returned to the cave.


    Soon, Gao Meng and other miners climbed out.


    "That''s great. I saved this black and red gold mine. I don''t need to be whipped."


    Lao Gao said: "the rainstorm is estimated to last another day. When the water level in the mine cave drops, we will go down to the mine immediately and mine more Black Hematite. After soaking in water, the mining difficulty will be reduced a little, which is also an opportunity for us."


    Gao Meng said, "father, just now when I went into the water, I found a high-quality raw ore. I estimated that it weighs at least 20000 kilograms. If I can find a way to get this raw ore out, it will be enough to complete the quota of this month."


    "20000 Jin..."


    Lao Gao frowned and said, "the larger the volume of Black Hematite is, the higher the quality is, but the weight is heavier and the texture is stronger. It is very difficult to separate such a large raw ore."


    "I can try."


    Su Chen said.


    "Well... Brother, you''ve helped us so much. Why bother you again?"


    "It''s all right. It''s a big deal. Just pay me." Su Chen said with a smile.


    He is now holding an empty storage ring, but he can''t even take out a dollar. Even if he goes to Baoxia Island smoothly, it will be a problem to eat there.


    "That''s OK." Lao Gao secretly made up his mind that the 1000 yuan core he had taken from Su Chen would be returned to him intact later. After all, he accepted such a great favor from others. It''s really outrageous to take the money again.


    After waiting for an hour, the rain outside the cave continued unabated and weakened. Some rain overflowed into the cave. Only a dike was temporarily built outside the cave to prevent rain from pouring back.


    However, the sea water in the mine has been almost drained, and the people successively went down to the bottom of the mine with tools.


    In the residual sea water, there is indeed a large black red gold raw ore. the ore content of this raw ore is very sufficient. The whole raw ore looks dark black and full of weight.


    "Just break him?" asked Su Chen.


    Lao Gao nodded: "this kind of raw ore needs to be brought back to the cast iron column for purification and smelting. The more it is broken, the better. It is convenient for handling and loading."


    Su Chen stepped forward and slapped the ore hard.


    Bang!


    The ore suddenly shook and a fingerprint like crack appeared.


    "What a powerful force!"


    "My brother is strong. I''m afraid even the base building experts may not be able to bear this slap."


    Everyone marveled and praised.


    Only Su Chen kept complaining from the bottom of her heart.


    The ore is too hard. If he slaps it, his palm will crack.


    Without Yuan Li to protect the body, even if the constitution is strong, it is only a physical body after all.


    You still have to use a mountain cutter.


    Su Chen picked up the mountain cutter, took a deep breath, spun out cylindrical holes in the ore, and finally dismembered the ore into fragments all over the ground in a few minutes.


    "Hey, boss Gao, look, the ore in here seems to have mutated into gold."


    Lao Gao went over to have a closer look, and suddenly stared in surprise: "this is... Red gold chalcedony!"
