"Open the supply device that holds the artificial spirit stones and let me see it," Night Wind said.
Luo Qing nodded and immediately turned on the supply device.
Because the artificial spirit stones need to be refilled, the supply device was designed from the outset to be able to be repeatedly opened and closed, making it very easy to open.
After the supply device was turned on, Ye Feng saw that all five hundred artificial spirit stones inside had turned into dust.
It was clear that the two shots from the wave cannon had consumed all five hundred artificial spirit stones.
Five hundred artificial spirit stones can be used to make five hundred spirit stone grenades!
"The price is too high," Zijing couldn't help but say.
"It is indeed a bit too much. So many artificial spirit stones can only make this wave cannon fire twice. Although the power is indeed great, it is still a waste," Xu Ping'an commented.
Rowling said, "It seems to be a failed product."
Upon hearing Rowling's summary-like words, Luo Qing lowered her head, her expression one of utter disappointment.
Ye Feng nodded in agreement and said, "Qing'er's wave cannon is indeed a failed product, but it is not without its merits."
Upon hearing the second half of Ye Feng's sentence, Luo Qing's eyes lit up, and she hurriedly looked towards Ye Feng.
Ye Feng chuckled and said, "Leave the battlefield to the soldiers. Chen He, Jiang Wei, you two stay here and keep watch in case anything unexpected happens. Old Xu, you stay here too, to deal with any emergencies."
"Qing'er, take this wave cannon and come back to Xinluo City with me. Luo Lin, you come too."
Luo Qing immediately put the wave cannon into her storage ring. Then Ye Feng grabbed Luo Qing and Luo Lin's shoulders, while Gongbu Qiuye grabbed Zijing's shoulder.
The air twisted and rippled, and in the next instant, they all vanished.
When they reappeared, Yefeng and his group had already returned to Silla City.
Upon entering the tent, Ye Feng opened a drawer and took out a stack of blueprints.
"Qing'er, take a look at this. This is a new type of cannon that I designed," Ye Feng said with a smile.
Luo Qing then took the blueprints from Ye Feng's hands and began to examine them without blinking.
Rowling, curious, leaned closer to take a look.
Gongbu Qiuye and Zijing, naturally, were not idle either; they also went over to look at the blueprints.
"So you had similar thoughts to mine, Ancestor! But we think a little differently," Luo Qing said, scratching her head.
Night Wind smiled and said, "Indeed, there are some differences. The new type of artillery I designed still uses the concept of a fully automatic explosive rifle. It can be considered an enlarged version of the fully automatic explosive rifle."
"My original intention in designing this cannon was to condense large bursts of flame as projectiles and launch them. However, when I was improving the burst formation, I discovered that the volume of the flames would become very unstable if it exceeded a certain range. Not to mention being unable to utilize them, it might even cause an explosion before it could be launched."
"This is a problem I've encountered, and I've been thinking about how to solve it for the past few days."
"However, the advantage of my new cannon over yours lies in its spirit energy supply device. Yours uses artificial spirit stones as a source of spiritual energy."
"But I directly inserted a set of spirit nets. With the spirit nets, I can continuously gather the spiritual energy of heaven and earth and fire continuously."
Luo Qing thought for a moment and said, "But Ancestor, in this way, the spiritual weapon supply device for the new type of cannon will be very large, since the volume of the spiritual network cannot be reduced too much."
“I know, but this new type of cannon isn’t meant to be carried around by people. Its size doesn’t matter. We can wait until the city walls are built and then install these cannons on them as defensive artillery.”
"We can also build several large ships and mount these new cannons on them as naval guns!"
Luo Qing exclaimed in surprise, "There's actually such a thing?"
“Of course, that’s possible,” Ye Feng said.
Luo Qing then said, "In that case, we can design the new cannon to be even bigger, the bigger the better!"
"It's not that the bigger the better, but it can definitely be a little bigger." Ye Feng nodded with a smile.
Then Ye Feng patted Luo Qing's head and said seriously, "Qing'er, combine our two designs and come up with a new one. I believe you will definitely succeed this time!"
"Yes, Ancestor, I will definitely not let you down!" Luo Qing nodded vigorously.
Ye Feng then looked at Luo Lin and said, "If you have time, you can also help Qing'er. It's very hard for her to do research and development all by herself."
"Understood, Ancestor, I'll be right there..."
Before Luo Lin could finish speaking, Luo Qing hurriedly refused, "No need, no need, I can study it myself slowly."
“With your aunt helping you, things will be easier for you,” Ye Feng said.
"It's okay, it's okay, I wasn't tired to begin with."
After Luo Qing finished speaking, she rolled up all of Ye Feng's blueprints, put them into her storage ring, and ran outside.
Zijing nudged Gongbu Qiuye with her elbow and asked, "Could you understand what they were just saying?"
“I can understand a little,” Gombu Qiuye said.
"How much is one point?" Zijing asked again.
“About half,” Gongbu Qiuye replied.
Zijing immediately looked surprised and exclaimed, "You actually understood half of what they said? I didn't understand a single word they said..."
Zijing was referring to the part about the design of the new artillery that Yefeng and Luo Qing had just discussed, which she hadn't really understood.
"Do you think they're like you? Do you think everyone is as ignorant and incompetent as you?" Rowling mocked.
"So what if I'm ignorant? I've already mastered the Shadow Escape Technique to the tenth level of perfection. Can you do that?" Zijing said arrogantly, hands on her hips.
Rowling snorted and turned her head away, avoiding eye contact with Zijing.
Suddenly remembering something, Rowling said, "Grandpa, I'm a little worried about Qing'er. She's been disappearing and coming out mysteriously these past few days. Several times I've looked for her but couldn't find her anywhere... Why don't we go and take a look? I have a feeling she's doing something bad behind my back."
"Aren't you overthinking it?" Ye Feng tilted his head and glanced at Luo Lin.
Rowling, however, said with great certainty, "My intuition has always been accurate; it's my woman's instinct!"
“Alright, then I’ll go with you,” Ye Feng said.
Then Ye Feng looked at Gongbu Qiuye, who smiled and pointed in a certain direction: "Miss Luo Qing went that way; her scent lingers in the air."
As a tree spirit, Gombu Qiuye has an extremely keen sense of smell, and can therefore track targets based on their scent.
"Then let's go."
As he spoke, Ye Feng led the way out of the tent.
