When the cannon rang out, Lena didn't look at the waves of dirt at the end of the training ground. Although the shell is equipped with a high-power explosive charge developed by the master, the caliber of the cannon body is not large, the power can only be regarded as unsatisfactory, and the firing range is decent. It is no exaggeration to say that the earth cannon in the underground world can also play a similar effect with a slight modification.

At the end of the third round of test firing, the red flag confirmed to be hit in the distance was raised high, and the craftsmen and testers began to nervously record various data. However, in the eyes of experienced craftsmen, several aspects of the tower gun's performance have reached the expected standards, and the next step is the boring and lengthy durability test.

"I'm sorry for pulling you over...... Only the first round of the tower gun test was more exciting, and the rest was a bit boring. Noticing the distraction of the craftswoman, Master Tresor took off the earbuds and said apologetically, "I just think that you are involved in one part of its forging and at least have the right to see it work." ”

"No, it's okay." The female craftsman responded, and her heart was already surging, "I'm just...... Thinking about the alloy. ”

Moments before the test began, Lena looked at the performance data of the alloy used in the barrel. The huntress was surprised to find that the data for both alloys was stronger than her prediction. Especially the ferrous metal, which is the main material of the gun body, has better hardness and toughness than she imagined before, in addition to the lower melting point and heavier, it can already be compared with some mainstream airship forgings.

This means that once the alloy can be melted in batches, there will be countless uses. The tower and other non-critical parts of the airship, other large auxiliary hunting equipment, and even the building materials of the field camp board house are all large consumers of ore and low-level monster materials. As soon as this recipe comes out, even if it can't solve the related needs once and for all, it can greatly alleviate the material gap of the Hunter Guild.

"Pure white metal......," Tresor said, "have you found out?" ”

As the cause of the previous trouble, Lena once thought that the white plates were ordinary pure white metal. However, after the master's refining, the ore has undergone earth-shaking changes in performance, even if it is thrown into a high-temperature furnace, it will not cause a disaster as the female craftsman said, and after all, she still made an oolong.

"Ah Ying didn't obey my orders, and he deserved to be punished." "Besides, you're here to save people, so how can I blame you for that?" ”

"What do you say to save people...... I just don't want to see that furnace destroy in front of me. Lena snorted, but the corners of her mouth lifted slightly. She was silent for a few seconds, then whispered, "I know who you are, the designer of the 'Flying Man'. Before I met you, I thought you were no different from those fastidious old guys. ”

In the impression of the purple-clothed hunter, the dragon master has always only made flashy things. She had seen the dusty "flying man" in the volcanic area, and she only thought it was a toy made by some dragonman when he was bored. Now that she saw Tresol's deity, she found that in addition to the rigor inherited from the bloodline, there was nothing similar to the dragon master in her impression. Renowned throughout the north for its high-performance explosives, its imaginative auxiliary hunting gear and its imminent alloy formula, this red-haired dragonman's forging path is actually quite in the style of the underground world, and it can be regarded as an outlier among dragonmen.

"I'll take it as a compliment." The master's ears twitched, the flag fluttered at the other end of the training ground, and the fourth round of test firing had been loaded. He gestured a few times for his men to go about their business, but his eyes looked appreciatively at the young woman in front of him.

Although Tresor is young, he is also an old monster with a lifespan of more than a hundred years in the eyes of humans. In the eyes of the master, although Lina's forging skills are still a little immature, her basic skills are exceptionally solid. After the cannon barrel was forged, the female craftsman's discussion of the alloy showed her rare vision and insight - it was a quality that could not be learned on the workshop, but it was extremely important for the research and design of hunting equipment, and for a time it made the dragonman also have a feeling of sympathy.

"Words ......"

"I-"

After a moment of silence, the two spoke almost simultaneously. Tresor smiled awkwardly and raised his hand to signal the lady to take precedence.

"I want a separate workshop, the biggest one." Lena bit her lip and demanded, "And half of the power of free forging every day." ”

"Of course." The master was stunned for a moment, then smiled.

"And the power of the furnace." Seeing that the dragonman craftsman agreed readily, the Shadow Hunter bloodline in the female craftsman became agitated, and she demanded even more.

"I can't believe it...... Our research on the 'talent' of the ancient dragon species has come much later than we thought, and we have made such great progress. Lu Yingying sat in the middle of the pile of books that were piled up into a small mountain, turned over a page of the book, and involuntarily sighed, "Isn't this kind of mysterious thing more difficult than topics such as ancient dragon ecology?" ”

"Unless it's taught by the cologne himself." Not far away, Feng Chen knelt on the floor, swept over the catalog with a heavy dark circle under his eyes, and the size and weight of the book in front of him were even comparable to a one-handed round shield, "I still vaguely remember that Fengshan Long once mentioned to me a scholar with a broken arm. Mo Lan of the previous generation had taught him a lot of knowledge, and it was not surprising that there was an explanation of talent among them. ”

"Oh-" the little scribe Yan admired, "now you probably know as much about the ancient dragon species as most of the scribes." I really envy you, if the scribe also had a dragon cavity, the path to studying monsters might be much easier. ”

The Dragonwhisperer didn't seem to find what he was looking for in the book, he closed the page, threw it into the pile of books he had read, and replied without looking up, "Trust me, you won't feel that way after you get it." ”

"I'm sorry." The girl sneered, and suddenly remembered something, "Wait, I have some impression of the great scribe you mentioned, he made a lot of contributions to the founding of Locklac. If that senior can talk to the ancient dragons......"

"Maybe you've studied the dragon cavity too!" The young hunter perked up and asked, "Great! What is the name of the senior? ”

"I'm not sure...... His predecessors did not leave many works, but he taught several heavyweight scribes who emerged later, and several of them were quite successful in the study of ancient dragons. Lu Yingying searched in her mind, and suddenly tapped her palm and said, "The history of the city of Locklac!" There must be a record of him in it! ”

"Sister Miaoling!" Feng Chen's face was overjoyed, and he hurriedly beckoned to the other end of the bookshelf, "Did you hear that?" History books are on your side, right? ”

"Who are you calling?" The little dragon man on the side was carrying a stack of thick books, tilted his head when he heard this, and said inexplicably, "Sister Miaoling left two days ago." ”

Feng Chen was stunned for a moment, only to find that there was really no half of a figure on the other side of the bookshelf, only stacks of books that had not had time to be sorted out were scattered on the ground. The young man scratched at his greasy hair, vaguely remembering that the Little Hunter seemed to have received a commission for a desert pterosaur and needed a female archer to fight. He finally took his attention off the books in his hand, looked around at the tall bookshelves around him, and asked a little confused, "What time is it...... How long have I been here? ”

"Lunchtime — and, you've slept here for nine nights." The voice sounded from the staircase, it was Qin Shuiyu who was let go by the guard hunter. The female head of the group raised the food box in her hand: "Put down the books quickly, let's eat something first." ”

For several days, the dust was spent in the library. There were a few more camping blankets in the corner, which seemed to have been moved there since the second day. The companions who helped organize and select the books came and went, and some of them clearly carried the injuries they had suffered during the commission, but they didn't remember who they were. The light of the stone-burning lamps on the four walls remained unchanged, making him lose his perception of day and night for a while, as if he were in a dream.

The young hunter nodded and stood up. After pouring too much knowledge into his head one after another, Feng Chen only felt that his neck had become extremely heavy. The dragon whisperer stretched his waist, and a beeping and peeling bone explosion sounded all over his body, and he finally felt a little more relaxed. The hunter's face changed: "Hell...... We've been in the library for so many days, so we won't cause trouble for the owner, right? ”

"Isn't it too late to think about it at this time?" Lu Yingying sneered, waved her hand and said, "Relax, you're not the first guy to sleep in the hall." I said hello to the guard hunters, and now the entire group is my apprentice, and it doesn't matter how long you want to stay here with my permission. ”

The advantage of having a high-profile university scholar as a father is that the little scribe can gain privileges in all sorts of unexpected places. Feng Chen thanked her gratefully, and patted his head again: "By the way, the history of Locklac City ......"

"Hey! It's meal time! The female leader had already followed, reaching out to block the way of the dragon whisperer. As soon as he approached his companion's body, Qin Shuiyu couldn't help frowning, covered his nose and said, "Hell...... Did you get into a fight with the monsters in the library? You've got to take a shower, or at least change your clothes – how long has it been since you've slept in? ”

"I forgot," the young hunter prevaricated, subconsciously tilting his head to the side, "don't worry about me, I'll rest when I'm tired." ”

The little head looked at Lu Xiu and the others on the side, and wanted to complain to them, but he saw that the eyes of the two were also obviously bloodshot. Lu Yingying did not have the physical support of the dragonman, and now she was yawning, relying on a spirit of curiosity.

"Sister Miaoling!" Feng Chen's face was overjoyed, and he hurriedly beckoned to the other end of the bookshelf, "Did you hear that?" History books are on your side, right? ”
