The reason why Zhou Zhou did not use the Aurora Tower on the Lord Battlefield previously was to protect his territory in reality.
The Lord Battlefield was just an activity after all. It was far less important than his foundation in reality, the Blazing Sun City.
If it used up all the energy of the Aurora Tower in the Lord Battlefield and its territory in reality suffered a powerful attack…
He would have no place to cry if he had no other way and could not use his strongest trump card, the Aurora Tower.
Now that he had this Diamond-Tier Elementary Grade Aurora Tower, Zhou Zhou felt that he could already use a portion of the Aurora Towers to participate in the Lord Battlefield with the help of other lower-level Aurora Towers.
"My Lord, the Aurora Tower is ready. Do you want to try it out now?"
Zhao Changshou said.
Zhou Zhou acknowledged.
"Let's begin."
Zhao Changshou nodded and said to the gunner beside him.
The gunner nodded and began to adjust the angle of the Aurora Cannon.
Soon, the muzzle of the Aurora Cannon emitted a faint white light, and a large amount of light elemental energy condensed at the muzzle.
The next second.
Buzz!
An Aurora Ray instantly shot out accompanied by a low hum!
It shot from the desert a hundred meters away and shot straight into the distance.
There was still a long track condensed from light elements in the night sky that was slowly dissipating after the gunner turned off the Aurora Cannon.
After that, the gunner activated Aurora Cannon – Polarity Mode.
A white light spot appeared at the muzzle of the Aurora Cannon.
This white light spot continuously gathered light elemental energy in the muzzle and quickly condensed into an incomparably dazzling and tiny light spot.
Zhou Zhou was not standing close.
Even so, he could feel the soul-stirring energy contained in this light spot.
The next second.
There was a puff and a dazzling light that was only a centimeter in diameter shot out and shot straight into the ground.
Zhou Zhou's vision was extremely good.
However, he only saw an extremely deep and small pit.
Zhou Zhou clicked his tongue.
So this is a Diamond-Tier Elementary Grade Kingdom-level building?
Such power.
Even ten Nezarios would be instantly killed!
He flew down from the city wall and came to the place where the Aurora Cannon—Polarity Mode had been activated.
A ditch five to six meters deep and 200,000 meters long shot from Blazing Sun City to the center of Thorn Dune before stopping.
Zhou Zhou clicked his tongue.
This range was a little ridiculous.
He came to the place where the Aurora Cannon—Polarity Mode had hit.
He realized that even though he was close, he could not see the deepest part.
"My Lord, what do you think of the might of this Aurora Cannon?"
Zhao Changshou, Zhang Kexuan, and Li Ya walked over and said with a smile.
"Okay."
Zhou Zhou said. Then, he felt that it was not enough to describe it, so he nodded heavily. "Very good!"
"With this Aurora Tower…"
"I don't have to worry about the safety of the territory even if I'm not in the territory for the time being."
"Elder Zhao, remember to arrange a Diamond-Tier Elementary Grade Aurora Tower for Sand Gold City after the construction of the Triumphal Arch is completed."
Zhou Zhou said.
As a commercial city, Sand Gold City had already begun to make a profit. Even though it could not compare to the fixed income of the monster ranch, be it channels, connections, reputation, and other things that could be seen or invisible, the efficiency accumulated by Sand Gold City far exceeded that of the monster ranch.
In terms of defense, Sand Gold City was no longer the 1,000 odd military professions from before under the rule of Qian Jiangsheng, the previous Finance Minister of the Aurora Kingdom, however, it was better to arrange a Diamond-Tier Elementary Grade Aurora Tower for it just in case.
"Yes, my Lord!"
Zhao Changshou said respectfully.
Li Ya and Yu Qiao's eyes lit up.
In the future, when they also had this Diamond-Tier Elementary Grade Aurora Tower, the pressure on their Aurora Kingdom against the Tahan Kingdom and the surrounding foreign race kingdoms would definitely be greatly reduced.
Zhou Zhou nodded and looked at Zhang Kexuan.
"My Lord, please follow me."
Zhang Kexuan immediately understood and smiled. Then, he brought Zhou Zhou to a red cannon that was half the height of a person.
This red cannon was about half the height of a person and two meters long and wide. It was completely scarlet and had an ancient style with a sharpness.
It was a Yellow Gold-Tier Advance Grade Mist Energy Cannon!
Zhou Zhou looked at its attribute information.
It was the same as the blueprint information he had seen previously.
Its range was 5,000 meters, and it was often used to kill giant creatures, creatures with powerful vitality, attack defenses, and naval battles.
Zhang Kexuan looked at the gunner beside him.
The gunner understood and immediately began to control the barrel, then pressed the firing button.
The next second.
BOOM!
A loud bang sounded in the distance.
A sand pit four to five meters deep and more than 20 meters in diameter appeared in the desert more than 3,000 meters away.
"This Mist Energy Cannon can kill giant creatures."
"If Nezario doesn't advance to Yellow Gold-Tier Advance Grade…"
"I'm afraid even its life would be in danger in front of it."
Zhou Zhou looked at the huge pit and could not help but think.
Of course.
Its most common function was to attack.
For example, it was used to break through the defense of the enemy's city wall in siege battles.
Thinking of this, Zhou Zhou suddenly looked forward to it.
Previously, because he did not have any siege facilities, he used conservative defensive methods most of the time on the Lord Battlefield and waited for the enemy to attack before attacking.
He would only send troops out to take the initiative to attack when he encountered enemies that he could not defend against.
Under such circumstances, the enemy had the advantage of the city wall. On their side, other than some subordinates who could fly, the soldiers who could not fly had to break through the city wall first before they could attack the enemies above and inside the city wall.
This meant that they had to pay the price of their lives to break through the city wall and attack the city.
Now that he had the Mist Energy Cannon, it was different.
This kind of war equipment that was specially used to attack the fortress could completely allow them to attack the city wall without paying the lives of their soldiers.
To them, this could completely greatly increase the efficiency of attacking cities and plundering lands!
"Old Zhang."
"We have to make more of this mist energy cannon."
"You can get other Alchemy Technicians to help you make Mist Energy Cannons at the Gnome Alchemy Workshop."
"Include the Alchemy Technicians who have just joined the Gnome Alchemy Workshop."
Zhou Zhou said.
"Yes, my Lord!"
Zhang Kexuan nodded.
Even though those new White Silver-Tier Alchemy Technicians were far inferior to him, a Diamond-Tier Intermediate Grade Alchemy Technician,
However, they could still be considered good helpers to help him make the Mist Energy Cannons.
The three of them chatted for a while after that. Then, Zhou Zhou and Li Ya chatted for a while before returning to the Lord Manor.
He washed up briefly and lay on the bed to rest.
The next day.
Early in the morning.
In the master bedroom of the Lord Manor.
Zhou Zhou opened his eyes in a daze.
A few seconds later, he woke up.
"It's the fourth day of the Lord of All Races Battlefield."
He thought silently.
Then, he opened the world channel and looked at what the Lords were discussing.
Not surprisingly.
Most of them were discussing the Myriad Races Lord Battlefield.
Most of them were discussing how to advance to the Green Bronze-Tier Elementary Grade and complete the basic goal of the Lord Battlefield activity.
It could be seen that they were all very anxious.
The other small group was discussing how to increase their strength and stabilize their ranks.
There were also a very small number of Lords who had completed their basic goals early on and were confident that their ranks would not drop to Black Iron-Tier. Therefore, their performance on the World Channel was quite indifferent, and some Lords even had an obvious sense of superiority.
Zhou Zhou closed the World Channel after watching it for a while.
Then, he washed up and walked out of the Lord Manor to the Gate of Summoning.
A text notification appeared.
[Prompt: Do you want to summon immediately?]
"Yes!"
Zhou Zhou looked at the Gate of Summoning expectantly.
