At night, the Divine Pavilion lights up the spiritual lanterns, which also means that the students are leaving.

Whether Su Dong is practicing or researching, he is simply a selfless madman, deaf to everything around him, other students sighed and put down the books in their hands, and reluctantly left, but Su Dong was still holding the books and gnawing wildly.

Ahem~

An old man in charge of the Divine Pavilion deliberately coughed beside Su Dong, but Su Dong still didn't move, and finally the old man had to push Su Dong before pushing him out of his state of selflessness, only to see Su Dong's wrist flip and pull out the knife hidden in his sleeve.

"What, you're going to give me a knife?" said the old man, who was stunned for a moment, and frowned.

Su Dong touched his head embarrassedly, and said with a smile: "I'm sorry, I'm used to it." ”

The old man pouted and said, "This is the academy, what are you doing with a knife in the academy?"

Su Dong said: "I'm used to it, I will also take it with me when I sleep." ”

The old man was speechless for a moment, raised his beard, pointed at Su Dong and said, "You kid, you are too vigilant! Forget it, I won't tell you this today, it's the closed time of the Divine Theory Pavilion, and you should leave here." ”

After that, the thin old man began to clean up the books in the yard, and many students were very unconscious, and they didn't know how to put the books back after reading them.

Su Dong looked at the old man's slow movements, one hand was still trembling, presumably suffering from Parkinson's disease, so he didn't think much about it, put the books he borrowed back in place according to the number, and helped him put away the other books scattered in the yard and the bookstore.

The old man stared at Su Dong twice and didn't say anything.

"I'll go back first, see you tomorrow at the old man!" Su Dong smiled politely and waved to the old man.

The old man was happy. replied: "You read the book and look stupid, the Divine Pavilion will not open tomorrow." ”

"See you the day after tomorrow!"

......

Temple.

Yisuo has been waiting for Su Dong for a long time. Su Dong forgot the time when he read the book, and came a little later than expected. The old man didn't care.

Pushing the door in, Su Dong gave a salute to Yisuo, and waited to take back the reward that Yisuo had given him.

Yisuo pointed to a package wrapped in oilcloth on the table, and said disapprerovingly: "I know that your spirit armor and spirit soldiers are broken, and it just so happens that there is a useless metal in the library, give it to you." ”

Su Dong was stunned for a moment, and said to himself: "Shouldn't I be allowed to choose what I want?"

Yisuo smiled: "Originally, this is indeed the case, open the inner library of the academy, let you pick three pieces at will." You can take whatever you like, but you ruined the third layer of the Death Trial, which made me very unhappy, so your reward is canceled, and you will be given this piece of pig iron, if you want it, don't pull it down. ”

Su Dong stuck out his tongue, it was not Su Dong's willingness to ruin the third layer of the death trial, and it was indeed very unauthentic for the old man to use this matter as an excuse.

Feel free to open the baggage. I saw that it was really a piece of pig iron, which had not been refined, and it was pitch black and quite ugly.

"Narrowly escaped death. I'll give you this thing in one go!?" Phantom Rain said dissatisfied.

Su Dong frowned slightly, a faint light flashed in his eyes, and he put this piece of pig iron into his star ring. He turned his head and said, "Come on, I'll take this piece of pig iron back." Thank you. ”

Yisuo sneered: "You're not angry if I give you a piece of rag?"

Su Dong said: "I am from the north, and I am used to being poor. This thing is worth two taels of silver, and no matter how small the mosquito is, it is still meat, so give it to me and take it. ”

After that, Su Dong whistled and walked away, looking at Su Dong's back for a long time, and said to himself: "Do you really want it?"

At this time, the foundry master Hai Buwei walked out from behind the temple with a stumbling face, and said to Yisuo: "Teacher, you are not fair, Su Dong has only been here for a few days, and he took away two things left by the Creation God Pingtian from you, you are too partial." ”

Asked Wudao, it was originally established by Pingtian, and he also left Wudao a lot of weird things, and the purple gold box that Su Dong took last time was left by Pingtian, called the Dark Moon Purple Gold Box, and now it is Su Dong's fourth great magic weapon.

Yisuo frowned and said: "I gave you this piece of pig iron, what can I do if you can't deal with it?" Besides, really follow the rules, let Su Dong go to the treasure house to pick it himself, he may not know what to pick away, the last night purple gold box has made me feel distressed for several days. ”

"Su Dong is so cunning, he knows that I have so many good things here, he will stare at me all day long, I can't stand it, no one can handle this piece of pig iron, give it to this kid, let him have a headache, and he can stop for a while." ”

The creator god Pingtian is a very amazing fellow, he left countless treasures and mysteries in the divine domain, such as this extremely ugly pig iron is one of them.

From ancient times to the present, the foundry master of Wudao Academy has tried to deal with this piece of pig iron countless times, but all of them have failed, and Hai Buwei has also tried it back then, this piece of pig iron is simply stubborn, not smelted, not neutralized by any kind of neutralizing agent, and thrown it into the high-temperature smelting furnace for seven hundred and forty-nine days, and it still comes out with a piece of smelly and hard pig iron.

Hai Buwei frowned and said, "Teacher, I can't handle this piece of pig iron, do you think Su Dong can handle it?"

The old man laughed very treacherously and said: "I can't deal with it, I can ask Su Dong for it again, this kid always comes up with a lot of tricks, let him accept the trap test, he ruined my death trial, this time I will give him the hardest bone in the academy for him to gnaw, see if he gnaws." ”

......

According to the prior appointment, Su Dong left Wudao to ask, and had dinner with Qinyin, Hua Yingyue, Zuofang, and Huang Buren, and went to the hospital to see Lei Tian.

After all, Su Dong and Zuo Fang are both active in the back mountains now, and they don't usually have the opportunity to meet, so having dinner together is the only time to communicate every day.

Huang Buren went to the alchemy department, Gong confessed that he listened to Su Dong's words, and was very strict with Huang Buren, tossing this little fat man to half death every day, and reciting the drug attribute table there while eating, even dreaming of endorsing.

There is no way, the stupid bird flies first, Huang Buren has no spiritual power, and if he wants to become a Danshi, he has to work a hundred times harder than others.

Another stupid bird is Hua Yingyue, this girl is really not a material for learning martial arts, a typical mouth style, Hua Yingyue can recite all kinds of martial arts backwards, it is really her turn to practice martial arts by herself, and she will make all kinds of ugliness, but Hua Yingyue is the same as her grandfather Hua Laohei, a little twisted, very serious and hard-working, it should be no problem to practice for a few years to protect herself.

Qin Yin is a character who can't sit still.,I've been mixed in many colleges at a young age.,Maybe after a while, when the freshness is over.,It's going to be another college.。

At night, Su Dong said goodbye to everyone and returned to Wudao, and Zuo Fang went to the cultivation room, where he slept every night, and when he couldn't find him, he went to the cultivation center to see, there was always a harvest.

Syllable~

The bag containing the pig iron was placed on the table in the studio by Su Dong, and then the package was opened.

Phantom Rain said disapprerovingly: "A piece of broken pig iron, what's so beautiful?" There are a lot of these things in the Ice Casting God Castle, and I haven't seen you look at it with your eyes." ”

Su Dong shook his head and said in a deep voice: "You are wrong this time, this thing is a treasure!"

"Baby?" said Phantom Rain in disbelief.

Su Dong smiled slightly and said, "Look at this guy, how heavy will it be?"

Phantom Rain said: "Judging from the block, there should be more than five hundred catties, and the pig iron has not been treated, and it is very heavy." ”

Su Dong asked again: "Then do you remember, where Yisuo put this piece of pig iron?"

"What does it matter about the wooden round table in his room?" Phantom Rain wondered.

When the words fell, Phantom Yu's face changed greatly, and he said in a deep voice: "The wooden round table can't bear this five-hundred-pound piece of pig iron!

Su Dong took this piece of black pig iron in his hand and said excitedly: "You are right, this thing is not five hundred catties at all, at most it is one catty!"

"A pound!"

Phantom Rain was shocked, it looked like a piece of pig iron, but the weight was only one catty! Obviously, this piece was probably not pig iron at all, but divine iron!

Su Dong didn't hurry to take this piece of pig iron to the scale and weigh it, and it was less than a catty, and it was only eight taels of sinking!

"Let's try the hardness of this thing! Assuming that this piece of pig iron still has enough hardness, it is the best material for making spirit armor!" Phantom Rain said excitedly.

The spirit armor is often very heavy, the composite metal in order to pursue defense, the density is extremely high, a complete set of spirit armor weighing more than a thousand catties is not an exaggeration, the heavy armor will even weigh tens of thousands of catties, even if the cultivation is good, wearing such a heavy spirit armor is also a burden.

So most warriors rarely wear spirit armor, and even if they do, they are half-body armor that exposes their hands, feet and thighs, no way, it's too bulky, and after wearing the spirit armor, they are as stupid as a bear, how can they fight?

The ultimate pursuit of the spirit armor is lightweight, and while reducing the weight, it can also have good defense, which is the best in the spirit armor!

This piece of pig iron is actually only eight taels? What is the difference between fighting in an eight-tael spirit armor and not wearing it? It is simply the best of the best!

Su Dong and Phantom Rain were very excited, Su Dong placed the pig iron on the ice casting roof, and gently cut it with a palm knife.

"Huh?"

Su Dong was very curious, he used about five hundred catties of force, and this thing didn't move at all?

Syllable~

Su Dong increased his strength to two thousand catties, but this piece of pig iron still did not react, and there was not even a small scratch.

"Shentie! It's really Shentie! It's lightweight, and the hardness is so high! I suddenly felt that how pleasing to the eye is, I actually gave you such a high-grade product! This is simply the raw material that a foundry can only dream of!" Phantom Rain shouted with wide eyes excitedly.

Su Dong was also very happy, and continued to increase his strength, trying to deform this piece of pig iron, wanting to know the approximate hardness of this thing, and then smelting and processing it.

But soon, Su Dong and Phantom Rain couldn't be happy, and Su Dong couldn't do even the slightest damage to this piece of pig iron with his strength of ten thousand catties!

Yisuo said it well, this piece of pig iron is not only not a super raw material that a foundry master dreams of, but a foundry's nightmare! A piece of pig iron of so high quality that it cannot be handled! No matter how Su Dong tosses it, pig iron is still pig iron!

It stinks and sinks hard, as if sneering. (To be continued.) )
