So Gongbu Qiuye found Yefeng and said, "I want to leave for a few days."
"Where are you going?" Night Wind asked curiously.
“I haven’t been in contact with our Tree Spirit Clan for far too long, probably over a hundred years, and my mother…” Gongbu Qiuye blushed as he said this.
Night Breeze smiled and said, "Alright, I'll give you a week off. Go and contact your Tree Spirit Clan... A week should be enough, right?"
“That’s enough. There’s a liaison station in the Divine Sword Empire where I can contact our Tree Spirit Clan,” Gombu Qiuye said.
"Then set off now, go early and come back early, and be careful on the road," Ye Feng instructed.
"knew."
Gongbu Qiuye nodded, then strode outside.
A day or so passed quickly.
Good news came from Luo Qing, so Ye Feng brought Zi Jing to Luo Qing's research lab.
Although Ye Feng promised to build a research lab for Luo Qing near the Spirit Medicine Research Institute, building a new lab would take time, so Luo Qing continued her research in her current lab during this period.
Moreover, not long after Ye Feng and Zi Jing arrived, Luo Lin also came.
"Look, Ancestor, this is the Wave Cannon I created by combining our two designs," Luo Qing said with great enthusiasm.
The night breeze nodded, admiring the enormous thing in front of it.
This new device was more than twice the size of the original wave cannon that Luo Qing had created.
This wave cannon is taller than a person, with an enormous, heavy base and a much thicker barrel than before.
"I have modified the spiritual energy supply device into a spiritual network structure, which directly gathers the spiritual energy of heaven and earth through the spiritual network and then transmits it to the fluctuation conversion array."
"I think this will definitely work, but it hasn't been proven yet..."
Luo Qing looked at Ye Feng excitedly as she finished speaking, and Ye Feng said, "Then let's find a place to test it out now."
As soon as he finished speaking, Ye Feng put the wave cannon in front of him into his storage ring, and then grabbed Luo Qing's shoulder.
Both Luo Lin and Zi Jing knew that Ye Feng was about to use teleportation, so they quickly grabbed Luo Qing's hand.
The next moment, Ye Feng and the others disappeared amidst the distorted fluctuations.
When they appeared, they had already arrived at the place where they had annihilated the more than two thousand red-tailed beasts.
The ground was littered with the remains of red-tailed beasts, and many places on the ground showed signs of being contaminated by toxins.
There was no other way; the toxins contained in the Red-tailed Beast were very special and their effects were extremely long-lasting.
So after the warriors and infantry of Silla Castle killed these Red-tailed Beasts, their blood flowed onto this land, and their toxins seeped into the soil.
As a result, the soil in this area became polluted and could not be cultivated at all. Even the weeds that grew from here contained toxins.
Fortunately, this place is quite far from Silla City, about 70 or 80 li away.
Therefore, even if this place is contaminated by the Red-tailed Beast's toxins, it will not have any impact on Silla City.
"Let's test it here," Night Wind said.
Luo Qing nodded vigorously, then stared longingly at Ye Feng.
After Ye Feng took the Wave Cannon out of his storage ring, Luo Qing ran over and said, "Ancestor, am I going to start?"
“Begin,” Night Wind said.
Luo Qing then pressed the switch on the wave cannon, and the spiritual energy supply device immediately started operating, frantically absorbing the surrounding spiritual energy.
Everyone present, whether it was Ye Feng, Luo Lin, or Zi Jing, could clearly feel a large amount of spiritual energy from heaven and earth surging in from all directions in a vortex, continuously flowing into the spiritual artifact supply device, and then being transmitted by the spiritual artifact supply device to the fluctuation conversion array.
The massive wave cannon hummed and vibrated, emanating a terrifying aura.
"You can fire now!" Luo Qing shouted.
"Then what are we waiting for? Fire!" Night Wind commanded with a smile.
Luo Qing then adjusted the cannon barrel and pressed the switch on top of it.
In that instant, a very thick, spiraling, crimson beam of light shot out from the cannon barrel and shone into the distance.
In an instant, a deafening explosion rang out.
A large crater, more than 30 meters in diameter, appeared on the ground, and traces of high-temperature melting were visible in the center of the crater.
"Such formidable power! Even a martial artist at the Divine Ascension Realm would be utterly unable to withstand this blast; they would be 100% killed by it!"
"Even if a martial artist at the Transcendent Realm consciously tries to resist, they may not be able to stop it, and nine times out of ten they will be injured!"
Rowling looked at the scene at the explosion site and said with a sigh.
Night Wind said with satisfaction, "This wave cannon is indeed very powerful, but it is still difficult to aim. However, after thinking about it carefully, I think that being difficult to aim is not such a serious drawback."
"Why?" Zijing asked curiously.
Luo Lin and Luo Qing also looked over at Ye Feng, as they also wanted to know the answer to this question.
Ye Feng explained, "It depends on the target of the wave cannon. If we use the wave cannon to hit a high-level martial artist, its aiming ability is indeed far from sufficient, and it will not hit the target at all."
"But what if we use it to attack objects that don't move? For example, the walls of cities and fortresses, large buildings, or large defensive formations."
"In that case, does the aiming ability of the wave cannon become insignificant?"
"If used properly, the Wave Cannon can become a powerful weapon for engineering domination!"
Upon hearing Ye Feng's words, both Luo Lin and Luo Qing showed expressions of sudden realization.
Zijing exclaimed, "Old Deng, so your target really is the other cities in the Southern Territory? It seems you weren't joking when you said you wanted to take back all the territory in the Southern Territory!"
"Nonsense, would I joke about something like this?" Ye Feng said irritably.
Then Ye Feng said to Luo Qing, "Let's fire a few more shots and test the wave cannon's endurance."
"Yes, Ancestor!"
Without hesitation, Luo Qing began firing the second and third shots.
The wave cannon fires approximately once every thirty seconds, with each shot lasting five seconds.
Unbeknownst to her, Luo Qing had already fired five times, creating one large crater after another on the ground in the distance, and even blasting a hill in half with a large crater in the middle!
"It's been five times in a row now, the endurance has been greatly enhanced! Ancestor, your design of this spirit network is much more reliable than using artificial spirit stones to provide spiritual energy!" Luo Qing said excitedly.
"But the drawbacks are also obvious."
Ye Feng frowned slightly as he looked at the spirit artifact supply device.
