Under Mu Xingwei's guidance, Lin Yu finally understood why he chose the giant blade.

The weapon is light and sharp, and it is indeed effective when attacking in groups, but when facing a strong person alone, it is not as powerful as a heavy weapon.

What Lin Yu comprehended was the mystical "violence", and the huge power carried by heavy weapons could complement the mysteries and cause greater destructive power.

After receiving the credits, Lin Yu walked to the exchange office, but the exchange of weapons had an independent windowsill, and under the guidance of the old man, Lin Yu walked to the armory of the academy.

The temperature inside the armory was much higher than outside, and there was a faint clanging sound inside, and an old man with goosebumps was sitting at the window with his eyes closed.

"Mentor, I want to exchange a weapon!" Lin Yu knocked on the table and said softly.

The sudden sound made the old man frown, slowly opened his eyes, looked at Lin Yu in front of him, and said unhappily: "Credit jade card!"

Lin Yu didn't speak, handed over the jade card in his hand, and then stood on the windowsill and waited quietly.

After the old man took the jade plate to check the basic information, he raised his eyebrows slightly, and asked in surprise, "Your name is Lin Yu?"

Although he didn't know what the other party meant, Lin Yu still nodded slightly.

Seeing that his identity was confirmed, the old man glanced slightly, got up and walked inside with a somewhat strange expression, and said by the way: "Come here!"

After thinking about it, Lin Yu couldn't guess what the other party meant, but he still followed according to his words.

As the old man walked inside, the fiery breath came to his face, causing Lin Yu's breath to stagnate, and he saw several topless men swinging the hammers in their hands beside several stoves, smashing them on the utensils on the stone platform, splashing a few sparks.

"What weapon are you going to pick?" said the old man without replying.

If it weren't for Lin Yu's sensitive ears, he wouldn't be able to hear clearly in this noisy environment.

"Knife or sword, it must be heavy!" Lin Yu immediately replied.

The old man nodded slightly, and Lin Yu, who was following behind him, couldn't see anything unusual, only to see the old man change direction and stride forward.

It didn't take long for Lin Yu to see a warehouse in the darkness in front of him, but the big men who walked by along the way all looked at Lin Yu with a playful face, which made him have a bad premonition.

Until he stepped into the warehouse, the messy furnishings made Lin Yu frown, and before he could speak, the old man said: "Just pick, pick it out and then register." ”

As soon as he finished speaking, he didn't pay attention to Lin Yu anymore, turned around and walked out as if he was fleeing.

Lin Yu looked at the old man's back, his face was pale, and he faintly heard the old man's mocking tone with those men.

"Old Ge, why do you still take someone to pick up things in the abandoned room, is that kid so poor that he can't afford to exchange weapons?"

"Hehe, Dean Li personally explained, you strike hard and don't meddle in things!"

......

The sound was gradually covered by the sound of striking iron, until it was no longer audible, Lin Yu looked around, and saw that there was thick dust everywhere, and his brows couldn't help frowning together.

"Li Jing, it's really naïve to play this kind of trick. After Lin Yu muttered to himself, he was ready to leave with his sleeves up.

"Don't worry!" Mu Xingwei hurriedly called Lin Yu!

"What's wrong?" Lin Yu wondered.

"Hehe, there's something good, that innermost corner!" Mu Xingwei chuckled.

Hearing this, Lin Yu looked towards the innermost corner of the abandoned room, and saw a dark sword body, a crack extending from the tip of the sword to the hilt, and anyone who looked at it was a waste sword.

"Old Wei, no kidding, is this thing still a good thing?" Lin Yu said in disbelief, but still walked towards the black sword.

"It's really been refined, and the sword refiner didn't control the heat well, so it caused cracks in this sword!" Mu Xingwei smiled lightly.

Lin Yu knew that although Mu Xingwei was a little unreliable, he shouldn't be joking about this kind of thing, so he stretched out his hand to lift the black sword, but he didn't lift it half a point with a slight force.

"Huh, is it weird?" Lin Yu whispered, and then put a lot of force in his hand, and then lifted it.

Dancing towards the void, Lin Yu nodded with satisfaction, and said to himself: "The sword is one meter four long and weighs about a thousand catties, but this crack that runs through the sword body, won't it shatter when touched?"

"This sword is built by Honggang stone, which is the raw material used by the generals of the Tang Dynasty to match the sword, and the sword body is also imitated, but we use it less to defend the country, so we don't have much experience in forging. ”

"The reason why there are cracks in the sword body is actually because there is a thunder stone in the Honggang stone, and the two stones do not blend with each other, and when the temperature is not well controlled, it cracks. Mu Xingwei talked eloquently.

Lin Yu blinked and said curiously: "Then you still say it's a good thing, is there any mystery that can't be done?"

"Yes, all things in the world are mutually reinforcing, although these two stones are not compatible with each other, but if this sword is placed in the wood source to nourish, the thunder stone will spread out of the crack under the nourishment of the wood source's spiritual power, until the Honggang stone of the sword body is completely wrapped, and finally penetrates inside. ”

"And the integrated sword body, although the cracks still exist, but compared to the real Honggang sword, it has more lightning strike characteristics. Mu Xingwei said with a light smile.

Hearing this, Lin Yu still waved the heavy sword in his hand in disbelief, and exclaimed, "I didn't expect the spiritual power in Mu Yuan to have such a miraculous effect!"

"If you just regard Mu Yuan as a spiritual power ball with relatively pure spiritual power, then you are very wrong, the existence of the five major source powers still needs to be traced back to the endless years. ”

"According to the ancestral records, when the Five Elements Clan stood at its peak, it was convenient for the world to collect the source of spiritual power, but the success is also the source power, and the defeat is also the source power, and the collection of the source power seems to cause the wrath of the heavens, and finally the boundless anger descends in the endless abyss, and the Five Elements Clan has since stepped down from the altar, and now the five major source forces are estimated to be the only few sources of spiritual power left in this world!" The vicissitudes of life were like traveling through ancient times, resounding in Lin Yu's mind.

Combined with Xuan Lao's explanation of the secrets of the five elements of the Divine Palace, Lin Yu began to see a corner of the chessboard, his advent must be inseparable from these five source forces, and the appearance of the five elements of the Divine Emperor is also the shadow of the five major source forces, maybe when he gathers the five major source forces, he will have the qualifications to know the chess game!

Burying the thoughts in his mind deeply, Lin Yu picked up his heavy sword and walked out of the door, since he has the ability to turn waste into treasure, he has to thank Li Jing for the opportunity he brings!

With the appearance of Lin Yu, the big men who were beating the equipment looked over one after another, and when they saw the heavy sword in Lin Yu's hand, they all smiled with ill intentions.

"Little guy, your eyesight is good, this Honggang Sword is a weapon used by the generals of the Tang Dynasty, and the lowest grade can reach the ground level, but I didn't expect to be picked by you!" With a slightly mocking tone, a big man said with a smile.

Lin Yu smiled slightly, then ignored it anymore, and wasted time and energy with these dogs.

Seeing that Lin Yu didn't care, Dahan was also in no mood, and then scolded in a low voice: "This waste turned out to be a dumb person, it's really a waste sword with a waste person!"

"Whew!"

A slight wind whistle swept through the ears of the big man, bringing a touch of blood on his cheeks, and the Honggang heavy sword, which was one meter four long, calmly crossed in front of the big man's eyes.

"If you want to have fun, I can accompany you, I don't know if you have the strength!" Lin Yu's cold words caused the entire refining room to drop a few degrees in vain, and his eyes full of murderous intent made the big man stop breathing.

Seeing that Lin Yu raised his sword and injured people, the big men in the entire refining room surrounded him one after another.

"Boy, the armory is not a place where you can go wild, you better put down the heavy sword in your hand!" a man dripping in sweat shouted.

"People don't offend me, I don't offend people, if people offend me, even if they are far away, they will be punished, do you want to try it?" Lin Yu said contemptuously.

The words full of murderous intent made the man silent a little, maybe he didn't know who Lin Yu was, but the young man who could easily wield a thousand-pound giant sword was naturally not an ordinary student.

"It's Gangzi's fault, I'll compensate you for him!" The man finally chose to give in, and the battle between the big guys was not willing to interfere with ordinary people, so he said softly.

"Boss, he's ......"

"Shut up, if you don't want to die, keep your mouth shut!" the man shouted in a deep voice.

Lin Yu stared at the boss of this group for a moment, then slowly put away the heavy sword in his hand, and chuckled: "Count yourself as an understanding person!"

After speaking, Lin Yu turned around and walked outside, and the people who were surrounded hurriedly made the way.
