Xu Xin refined some more steel and gave it to Li Wenxi. He also gave Li Wenxi some coal.
According to his observation just now, a piece of coal (green) can keep the furnace burning for an hour, which is shorter than the burning time of a piece of green-grade wood.
But coal is easy to obtain. No one knows when all the coal mines will be mined. And one pickaxe can produce more than ten or twenty pieces. Compared with a green-level tree that only produces five pieces of wood, it is indeed much easier to obtain.
Most importantly, coal can improve the efficiency of furnaces.
"This is coal!" Li Wenxi was also surprised. "It can actually improve the efficiency of the furnace! Have you found a coal mine?"
"Yes, it's near my tree house, buried five or six meters underground."
"So it was buried underground. I was wondering why I couldn't find the coal mine... but you found it underground!" Li Wenxi blinked. "Could it be that your alchemy ability helped you find it?"
"It should be similar to your ability to find ore." Xu Xin said with a smile on his face.
“… Hey, I’m going to help you practice the steel block!”
After hanging up the video, Xu Xin came to the art room and sat down at the engraving and painting workbench.
At his current speed, he could produce one small engraving in fifteen minutes, and 40 points of decoration in an hour.
After eating an orange to keep his mental strength at its peak, Xu Xin picked up the carving knife and immediately got into the state.
Soon, the first carving, the small carving promised to Li Wenxi, was made. This time he carved a beautiful girl standing with her hands on her hips, with the proportions of her head, body and legs perfectly restored, and even her figure was perfectly restored.
The prompt sounded, telling him that he had increased the decoration level by ten points. Xu Xin put the small carving aside, took out another green-level crystal, and continued carving.
Immersed in the carving, Xu Xin could not feel the passage of time. Soon, small carvings were created from his hands. The images of the small carvings were all animals, blood-patterned rabbits, blood-patterned cats, and blood-patterned swordfish. These were the three intermediate mutant beasts he had killed.
When the fourth carving was completed, the carving of the blood-marked swordfish emerging from the water, Xu Xin breathed a sigh of relief, put down the carving knife, and leaned back in his chair. He looked at the time, four carvings, no more, no less, exactly one hour.
Really good, one hour, 40 points of decoration.
However, this time the prompt tone changed.
A mutant sailfish red crystal wither (green) is detected in the tree house. The decoration degree of the tree house is +10. The current decoration degree of the tree house is: 319.68 (266.4+53.28).
The number of crystal carvings (green) in the tree house has reached the upper limit. Adding more will not increase the decoration level.
… As expected, there is also an upper limit to the number of crystal carvings of the same level, but the upper limit is much higher than that of the unprocessed basic materials.
Art also has its limits.
Xu Xin calculated that before today, he had carved a statue for Coco, Mimi, Ah Fu, the Silver King, his beloved concubine, and the two little guys, a total of six green-level small carvings. Now he had a carving that he would give to Li Wenxi, and carvings of three intermediate-level mutant beasts.
In total, there are ten.
The upper limit of the number of crystal engravings (green) is ten. Each crystal engraving (green) can increase the decoration level by 10 points, so ten of them is 100 points. Combined with the 20% decoration increase rewarded from the last event, these crystal engravings (green) bring him a total of 120 points of decoration.
A lot. After all, the green-level crystal that had not been processed could only add 6 points of decoration in total. His unprocessed purple-level crystal could only add 5 points of decoration.
But Xu Xin was still a little disappointed, he actually hoped that the degree of decoration could be increased infinitely. Now it seems that he still needs to use other materials and methods to increase the degree of decoration.
There is no need to worry about it for now. He can also use mahogany paper for painting to increase the decoration, and mahogany is also one of the materials for carving.
Taking out another green-level crystal, Xu Xin started carving again. After all, one of these statues was to be given to Li Wenxi, so he naturally had to make up for it.
The carving is complete, it is a small carving of a wild boar. As expected, there is no hint of increased decoration this time.
Xu Xin placed the statue on the bookshelf and was about to contact Li Wenxi to inquire about the progress of the steel refining when suddenly, a prompt sounded in his ears.
The carving proficiency is achieved and the artist level is raised to the entry level.
… Artist level increased
Xu Xin immediately clicked on the artist option and found that the small line about the level had changed.
Artist Level: Advanced.
The artist level has reached the next level and has been advanced!
The prompt said that he was promoted because of his carving proficiency. Xu Xin calculated that, including the two carvings given to Li Wenxi, he had made a total of twelve small carvings, and finally advanced to the entry level.
His own level is indeed entry-level, but with the blessing of the Deep Sea Pearl (Blue), his artist level has been raised to the advanced level!
Can advanced artists already process blue-level crystals
Xu Xin immediately took out a blue crystal. Compared to the green crystal, the blue crystal was much larger. The green crystal was only the size of an egg, but the blue crystal was as big as a fist.
The blue crystal still had a few marks left on it from the last time he carved it. That time he only carved a few cuts and then had no idea where to cut further.
When Xu Xin picked up the carving knife, that immersive feeling appeared again, making him overjoyed.
As expected, he could process blue-level crystals and make blue-level engravings! This made him feel a little disappointed after learning that there was an upper limit to crystal engraving, and he immediately immersed himself in engraving.
He didn't know how much time had passed, but the vibration of his watch woke him up. It was a video call from Li Wenxi.
Although he felt that the carving was flowing smoothly and his movements were as if assisted by a god, the completion rate of his blue-level carving was very low at this time, even less than 10%.
Looking at the time, Xu Xin frowned.
An hour had passed since he started carving this blue crystal!
This... Not even 10% of the work is done in one hour?!
This blue-level engraving is really time-consuming! From this perspective, to complete a blue-level engraving, even if you do nothing else, it will take a whole day!
…It was a waste of time. For the time being, he should use other methods to improve the decoration level. After all, he could make many green-level artworks in an hour.
Green-level painting and green-level mahogany carving can both improve the decoration level. After upgrading to the advanced level, his artistic creation speed should be faster.
First fill all of these up to the upper limit, add some amplification points to the art room, and then consider the higher blue-level crystal statues.
The watch was still ringing, and Xu Xin answered the video.
"What are you doing? Why haven't you answered the phone for such a long time?" Li Wenxi asked in confusion, holding a piece of metal with a bright silver metallic luster in his hand.
"I'm carving it for you," Xu Xin raised the little beauty carving in his hand and teased, "You almost ruined all my efforts and almost broke your legs."
"Ah? Oh, then... it's not broken, right?" Li Wenxi's voice suddenly became much softer, with an "I was wrong" expression on his face, and he asked cautiously.
"I was just kidding. It's okay. It's perfect." Xu Xin tossed the statue in his hand.
Li Wenxi's eyes widened, and he quickly stopped her: "Hey, don't throw it! What if it breaks? That's me!"
Xu Xin took the statue and placed it on the table. He had already seen the steel block in Li Wenxi's hand. The steel block was emitting a blue light, and it was obviously a blue-grade steel block.
"How is the steel block being refined? Is the speed fast?" Xu Xin asked while initiating a transaction with Li Wenxi.
Li Wenxi also accepted the transaction directly, took the statue in his hand, and looked at it with love.
"Hurry up, we have already refined a lot. Um, wait a moment, I will put the statue away first!"
She stood up and walked to another room, carefully placing the statue on a shelf. On the shelf was the statue that Xu Xin had given her before, which was engraved with her lying on the sofa.
After doing all this, she sat back on the sofa and picked up the silver-white steel block that she had just placed on the wooden coffee table.
"That's it, steel blocks! I have refined some green and blue grade steel blocks. The time it takes to refine a steel block is also related to the grade. It takes much less time to refine a green grade steel block than a blue grade steel block. Um... it only takes a few tens of seconds to refine a green grade steel block, while it takes fifteen minutes to refine a blue grade steel block."
It is time to let professionals do professional things.
It takes Xu Xin 50 minutes to refine a block of blue-grade steel, but it only takes Li Wenxi 15 minutes.
Moreover, she has many furnaces. With the support of the smelting room amplification, even with many furnaces, the indoor temperature can be guaranteed not to be too high, which will not cause a fire. She can also enter the smelting room and control the furnace without cooling, which directly increases the refining speed several times.
"Moreover, one bottle of Steel Fire can continuously refine five green-grade steel blocks, but can only refine one blue-grade steel block. So, does your Steel Fire consume a lot of materials?"
A serving of Steel Fire only requires one kilogram of mutant vine juice and 25 pieces of coal, which isn't a lot.
Coal is currently inexhaustible. Even if my beloved concubine dug more than a thousand pieces of coal, the coal mine seemed to have not changed at all.
Even if the juice of the mutant vines is exhausted, with his current strength, he can easily jump back and forth to the edge of the protected area, attract the vines to drill out, kill them, and collect the juice.
"It doesn't take a lot of materials. Give me the steel first, and I'll see what I can make."
"good."
Li Wenxi also sent him all the steel blocks.
"... So rich?" Looking at the materials in his hands, Xu Xin felt a little numb.
Xu Xin gave her a total of twenty portions of steel fire, and she returned him twenty-eight portions of steel blocks.
Among them, only ten pieces are green grade, and the remaining eighteen pieces are blue grade steel blocks!
The moment he got the block of steel, the formula for steel was quietly unlocked.
