The trading center was as lively as usual, and Su Dong wandered absentmindedly, looking up from time to time to glance at the tasks entrusted to the company.

Now Su Dong needs a large number of spirit crystals, assuming that there is enough time, Su Dong believes that he will accumulate a lot of wealth with his ability, the key is that Su Dong needs money right now to meet the needs of himself and Zuo Fang's cultivation.

Those low-value tasks don't need to be seen, the rewards are too small, and those high-value tasks take a lot of time, and seeing that the preliminary competition is coming soon, Su Dong doesn't have time to complete those time-consuming tasks.

Just thinking about it, Su Dong walked to the relatively clean northwest corner of the trading center, which is the technical solution area, and all the technical problems encountered in the study will be listed here to solve, about the elixir, casting, all kinds of things.

Su Dong glanced at the problem on the brand, and his footsteps naturally stopped, this is a casting system raw material ratio problem, and the person who released this question hopes to find a compromise solution to create a second layer of spirit armor that is light and thin, and can defend against the attack of water system spiritual power.

Usually the spirit armor does not make many layers, after all, it is metal, and it is heavy to wear on the body, and the two sets of metal spirit armor will also rub against each other and make ugly sounds, the person who posted the problem probably has some special needs, so he wants a set of inner armor to prevent the spiritual power of the water system, and it is possible that he is afraid of assassination and wants to wear it when he sleeps.

In short, this question worth ten white spirit crystals is simply at his fingertips in Su Dong's opinion, the inheritance of the ice god is ice casting, but he is also very good at the fusion of raw materials, most of the materials used by Su Dong to build the spirit soldier spirit armor are fused, and several metals are combined together.

After thinking about it, Su Dong took off this wooden card, there is a paper behind the brand, and the question is on it, you only need to write down the answer, and if the answer is valid after the owner of the wooden card verifies it, the trading center will be notified to pay.

Whew~ Su Dong wrote down the formula of fused metal and the key to it in one go, and then signed his account number in the trading center.

Handing over the wooden card to the staff of the trading center, Su Dong wanted to turn around and leave, after all, the number of these ten white spirit crystals was too small, and Su Dong just made some extra money.

The person in charge of this area is called Liu Kang, who is not too old, and he looks like he is in his early thirties, Su Dong solved this casting problem with an understatement, which surprised Liu Kang very much.

Su Dong was able to solve the problem so quickly, he was undoubtedly a foundry, and the foundry master in the Daodao Academy was not as young as Su Dong.

After putting away Su Dong's answer, Liu Kang said: "Do you want to answer other casting questions, in fact, there are many problems accumulated over the years, and only a small part of them are on the surface, and there are many unsolvable problems in the back." ”

Su Dong was stunned for a moment, and asked very utilitarianly, "How about the income?"

Liu Kang said: "The income is actually quite high, after all, this is a problem of the casting department, and the number of qualified foundry masters in the college is very rare, besides, those masters do not bother to answer similar questions, they always think that working materials is opportunistic, it is better to practice their own exercises with peace of mind, don't always think about what the exercises can't do with materials to make up." ”

Su Dong nodded slightly, the caster doesn't like to drill the tip of the horns, which is very common in the divine domain, the regular caster believes that as long as the skill is deep, he can solve all the problems encountered in casting, and the inheritance of the ice god is to pursue the limit, the practice must be to the limit, the raw materials must be to the limit, and even the casting itself is also blessed with multiple spiritual powers, which is very different from the ordinary caster's desperate efforts to improve the level.

The pursuit of grade is also human nature, according to the current grade division, as long as it is a great caster, no matter what the actual effect of the things he makes, it must be a high-quality product, and the ice casting series is more practical, even if Su Dong, a Yeluzi caster who has not taken the grade, can still create a high-quality product.

There is no way, rank is status, like Ye Xiaosheng, the foundry master Ye Dong met before, is a typical example of only pursuing rank, in order to preserve his spiritual power to advance, he even refused to build a spirit armor.

What's the use of a caster who doesn't build anything, no matter how high his rank? It's not a show.

Since Liu Kang said that the benefits of solving problems are good, Su Dong asked him to take those problems that have accumulated over the years, anyway, it doesn't take much time, and it is better to earn some money than nothing.

It's just that Su Dong didn't expect that there were so many problems accumulated in the academy, Liu Kang hugged a big wooden box and put it on the table, and there was dust on it, Liu Kang was a little embarrassed to wipe the dust off it, and said: "This is one of the boxes, it's been a bit long, sorry." ”

Su Dong is a typical utilitarian, he opened the box and asked curiously: "These are all questions from the past, I'm afraid that the person concerned has graduated, and I will answer that someone will give money?"

Liu Kang said with a smile: "You can rest assured that when the question is handed in, the fee has already been paid, and the money is stored in the trading center, you just have to answer, even if the party has left the academy, as long as your answer is correct, the trading center will also pay the fee." ”

Su Dong nodded slightly, picked up a few questions and looked at them, there was no problem, most of them wanted to hide a little greasy in the material, Su Dong learned ice casting, took the extreme route, and this is what he is best at.

And the cost paid is quite high, usually there are ten or eight white spirit crystals for a problem, and the high one can even reach dozens of white spirit crystals.

Without thinking much about it, Su Dong lay on the table and began to solve the difficult problems of these materials.

Time passed unconsciously, and Su Dong accumulated a thick stack of answers around him, and Su Dong even found some fun in the process.

Learning is one thing, you don't have to forget sooner or later after learning, Su Dong once spent a lot of time recording the material table and ratio table in the Ice God Inheritance, and he didn't use it much for a while, and he was already a little rusty, and now this situation is like an exam, Su Dong needs to constantly recall what he has learned to solve other people's problems.

And because there are a lot of students who ask questions, there are also various ideas, for example, there is a guy who actually wants to use ice-based spiritual power as a traction to create a storage box that can turn water into ice, so that he can make his own ice cream to eat, a bit like a refrigerator in his previous life.

This kind of question is very interesting, not to mention that Su Dong doesn't like to eat popsicles very much, and even if he does, he will never take the time to study this thing, but now that someone has paid for twenty white spirit crystals, Su Dong doesn't mind building an otherworldly refrigerator.

There are so many of them, Su Dong began to admire the visions of these students a little, after all, one person's thinking is limited, and if you put many people's thinking together, it will become very strange and fun.

About two hours later, Su Dong finally completed the solution of these hundreds of questions, and Liu Kang calculated that there were more than 4,000 pieces of Bai Lingjing's income!

Su Dong was also taken aback by this yield, and was pleasantly surprised.

"One more box. Su Dong said to Liu Kang.

"Okay. Liu Kang happily agreed, according to the rules, the trading center will take a percentage of the income, as a commission, Liu Kang himself can also earn a little money from it, so he is particularly attentive to Su Dong, after all, the more questions Su Dong does, the more he earns.

Su Dong was like crazy, burying himself in a big pile of questions, and he kept writing with a goose feather hard pen in his hand.

...... The foundry department can also be regarded as a big department of the Dao Academy, after all, the status of foundry is high, and everyone wants to be a glorious foundry, so he sharpened his head and squeezed towards the foundry department.

It's a pity that the casting road has very high requirements for talent, and only a few dozen of the 3,000 students can successfully graduate, and there are only a handful of successful students, and the vast majority of students will transfer to other easier departments after a few years because of their poor talent.

Hai Buwei is the head of the foundry department, usually a good man, he will accept if he wants to learn casting, and carefully guide until these students are found to really have no talent to do a good job in casting, Hai Buwei will give up the plan to let students become foundry.

It can be said that Hai Buwei has done his best to train as many foundries as possible for the college, but unfortunately casting is really difficult to learn, and the talents have gradually withered over the years, which makes Hai Buwei sad.

Near the end of the evening, the trading center sent a box, saying that someone had answered a lot of questions, and these questions were accumulated in the past, and the subject was no longer in the academy, and the casting department needed to be determined.

Hai Buwei's eyes lit up, and he became interested at that time, and asked curiously: "There are hundreds of questions here, all of which were answered by one person?"

"Exactly, I heard that it was Su Dong, the one who invented the Fury of Chaos for the Spirit War Department not long ago. ”

Hai Buwei nodded again and again, of course he had studied the Fury of Chaos, but Hai Buwei was kind-hearted, and felt that Su Dong's spirit crossbow was too vicious, so he didn't like Su Dong very much.

"The guy who can invent the wrath of chaos must be a vicious existence, it seems that this Su Dong does have real talent and learning. Hai Buwei picked it up and took a look at the inscription paper, and sighed in his mouth.

"The answer... It's a strange way of thinking!" Hai Buwei muttered to himself.

Greeting his colleagues in the office, Hai Buwei said: "Let's take a look, I'm afraid that there will be some evil guys in the foundry, this Su Dong is simply evil, and he actually proposed to use a hundred chops of steel to add carbon crystals to improve the wind spiritual defense of the finished product." ”

"Hundred cut steel and carbon crystals are easy to burst, after all, they are all extremely caste raw materials. Hai Buwei's colleague walked over as he spoke, and took Su Dong's answer and took a look.

"Hai Ye, although this kind of fusion is biased, but there is a door! He used the copper as a neutralizing agent, and the water chong selected by the forging technique just released the energy of the two extreme caste metals, according to this way, I am afraid that the finished product will really have a good wind system spiritual power defense. ”

Hai Buwei smiled bitterly: "That's what I'm going to say, it's just that the sword goes sideways, he actually succeeded! ”

Originally, it was time to get off work, but these professors of the foundry department didn't leave when they saw Su Dong's answer, and stayed to discuss them one by one.

Su Dong's ice casting technology is naturally not said, theoretically it does work, in this first batch of solutions, there are no mistakes, all of them are successful!

Just when Hai Buwei and the entire casting team were amazed, the second box of solution answers arrived.

"So fast!?It's only been less than two hours, and Su Dong has solved so many problems?" Hai Buwei asked in surprise.

The staff of the trading center who sent the answer said with a smile: "Now the trading center is a sensation, within four hours, Su Dong swept the topic of 10,000 white spirit crystals! The speed at which he made money created a new record since the establishment of the trading center!"

"And he asked people to move out all the topics that have been accumulated over the years, and it seems that he wants to clear the field at one time!"
