Indeed, artillery shells on land do not have to consider the resistance of the seabed, nor the conflict between sea water and gunpowder.
To make underwater cannonballs, one must be a mage with both water and fire elements, and the mage must have integrated the water and fire elements to a certain degree.
And this mage must also be an alchemist.
It is very difficult to meet these three conditions, which shows how powerful the Poison God was back then.
Su Luo suddenly thought of Xie Xiuluo. This old man had known that he had no shells, so he gave her the empty shell of the sea cannon and even sold her one...
Su Luo's thoughts turned to the Poison God Tower again. The first floor alone had such goodies, so what about the second and third floors? What about the fourth and fifth floors?
After putting the Immortal Palace into the space, Su Luo felt at ease.
The four layers at the back slowly opened up. The most important thing was that the little black cat would have food for a long time, and she no longer had to worry about finding poison for the little black cat.
Moreover, Su Luo also discovered that the toxins in the Immortal Palace were stage-specific.
The further away from the central medicine garden, the weaker the poison.
Therefore, the little black cat can start absorbing the toxins from the edge, and then slowly approach the center after its strength increases.
After finishing the matter here, Su Luo prepared to go back.
Although she had let her team escape before, she was still worried about them.
So when going back, Su Luo sped up.
Fortunately, Su Luo took over the Immortal Palace. Otherwise, it would be impossible for her to get out from the bottom of such a deep vortex now.
When Su Luo went back, she followed the same route she came. She first passed the Crystal Palace and then walked back from the Crystal Palace.
On the way, Xiaoyu said that the fairy palace could move very fast on the seabed, so Su Luo took out the shrunken fairy palace and turned it into a submarine. She and Xiaoyu sat inside, watching the scenery moving backwards.
Hey!
Su Luo suddenly realized that something was wrong ahead.
Because the water waves were vibrating abnormally, and there were also sounds of sea beasts roaring.
Sea monster?
Su Luo thought of her sea cannon. She hadn't used a single one yet. She really wanted to know the true power of the sea cannon so that she could use it with ease in the future.
Xiaoyu held the little koi fish in her arms and looked at Su Luo excitedly, her little face flushed.
This child has been staying in the Biyu Immortal Palace under the sea since he was born and rarely goes out, so he must be excited about everything, right?
Su Luo smiled faintly: "Then let's go see how powerful this weird sea beast is, and try out our sea cannon by the way!"
So, Su Luo drove the Biyu Immortal Mansion, which looked like an immortal mansion but had the function of a submarine, and rushed towards the place where the sea beast was roaring.
There is an underwater cave ahead.
The cave is a hundred meters high and a hundred meters wide, with nine bends inside and is bottomless.
When Su Luo was hesitating whether to go in, a shocking cry of pain suddenly came from inside!
Hey, that sound...
Su Luo just felt that the voice was familiar, as if she had heard it somewhere before.
Soon she remembered, wasn't this Murong Fang's voice?
How did he end up in the cave?
Soon, another shrill scream was heard from inside.
Isn't this voice Chen Xuejiao?
Soon, another series of sharp sounds were heard.
The sounds rose and fell, of different pitches, and when combined together, they were like a strange melody.
