Each spirit stone cannon requires a large amount of spirit stones.
However, what Lu Yu is most indispensable for is spiritual stones.
Just the wealth of the Suppressing Army King that he had acquired on Ancient Dust Star had already made Lu Yu extremely wealthy.
Not to mention, he obtained another complete spiritual vein on Niehai Star.
With his spiritual veins, Lu Yu has an endless supply of spiritual stones at his disposal. He can even use these spiritual stones to establish a sect and recruit a wide range of subordinates.
Lu Yu is now a wealthy man. There are very few people in the entire Yu Dynasty who are richer than him.
Everyone in the Qianlong Corps naturally knew about Lu Yu's wealth.
Therefore, everyone did not pay attention to these consumptions at all.
Another hundred guns were set up.
Looking around, the entire battleship is surrounded by densely packed gun barrels, which is very shocking.
Boom! Boom! Boom!
Following a violent bombardment, the overwhelming monsters in front of them fell down in pieces, turning into blood on the ground.
The light from the spirit stone cannon that filled the sky was also seen by Cao Bao and others behind him.
"Who are they?"
All the generals present were shocked.
Even though they have led many armies, they can only activate a dozen spirit stone cannons at most each time, and after firing a few rounds, they will start fighting at close range.
There is no way around this, because they simply cannot afford such horrific consumption.
However, the battleship in front of them greatly exceeded their expectations.
Two hundred spiritual stone cannons blasted them all together.
Just like spirit stones cost no money, countless spirit stone cannons criss-crossed with light, and every time they flickered, thousands of monsters died.
"Ho! Human beings, seeking death!"
Finally, some strong ones among the monsters could no longer sit still.
This was a huge shark, its body was as big as a village, its eyes were blood-red, and its two rows of sharp teeth were stained with blood.
As soon as this shark beast appeared, all the monster beasts in the beast tide immediately became more ferocious, roaring crazily and rushing toward the Qianlong Corps' warship.
"Sir, do you want me to swallow this little fish alive?" Ao Guang licked his lips and looked at the shark with excitement.
Although the Dragon Clan is noble, they also belong to the Demon Clan.
If he could swallow the demon elixir of this shark, it would be of great benefit to his practice.
Lu Yu shook his head: "We have no time to waste. There are at least a dozen demon kings behind here. Can you kill them instantly? Give me the order and add three hundred cannons to crush them!"
"yes!"
Dai Feng and Lu Jingsheng answered excitedly.
Before leaving the camp, the Hidden Dragon Corps captured nearly half of the spirit stone cannons in the camp.
Although spirit stone cannons are precious, there are craftsmen in the military who specialize in weapon manufacturing and can be mass-produced.
What's more, if you want to use the spirit stone cannon, the number of spirit stones required is not a small amount.
Therefore, Xu He approved it almost without thinking.
But even as a disciple of the Xu family, he never thought that the consumption of spiritual stones by these spiritual stone cannons would be nothing more than a drop in the bucket for Lu Yu.
Behind the battleship, the staff and others were shocked when they saw the shark monster appear.
"No, the battleship in front was too loud and attracted all these demon kings!"
"General, now is the best opportunity to attack the Sea Saint Star. Let us also help!"
Several generals made suggestions one after another.
Since there is such a fierce path-breaker like the Qianlong Corps, it would be unreasonable for them to continue to retreat.
