One shot, 10 million

At this moment.

The power of the Immortal Slayer Cannon had been upgraded to the level of a Three-Tribulation Martial Immortal, and each shot consumed many times more spirit jade.

Su Lang estimated that firing one shot would probably consume ten million top-grade spirit jade!

Of course, if the Sun-Shattering Divine Thunder was used as a projectile, then only a small amount of spirit jade would be consumed.

“Tsk tsk!”

Su Lang clicked his tongue in wonder, “This cannon shot is really expensive.”

Just then.

The artifact spirit of the Immortal Slayer Cannon emerged from its main body.

It resembled the size of a child, but it hadn't sculpted its face, looking like a soft, crystal bun.

“Cannon!”

“Fire the cannon!”

The Immortal Slayer Cannon's artifact spirit floated in front of Su Lang, emitting a thunderous sound.

It was truly a sound like thunder!

“What the heck!”

Su Lang muttered with a speechless expression, “Could you speak a little softer? Is there any need to shout when we’re this close!?”

At the same time.

He discovered that the Immortal Slayer Cannon's artifact spirit was as naive and innocent as Little Hai, and its intelligence seemed a bit concerning.

However, Su Lang had no complaints about this.

An offensive immortal artifact, before being properly taught, was like a super mischievous child with incredible destructive power.

As long as the Immortal Slayer Cannon's artifact spirit wasn't a Husky-like character, firing cannons everywhere and tearing down homes, then everything was fine.

“Hmm, the artifact spirit of the Sky Ocean has a name, so I’ll give you one too.”

Su Lang looked at the artifact spirit in front of him, and after some thought, said, “From now on, you’ll be called Little Cannon.”

“Cannon!”

“Little Cannon!”

The artifact spirit roared happily, its voice soaring into the sky, even making Su Lang's eardrums tingle.

“Hiss!”

“It seems Little Cannon also has a bad habit that’s hard to change!”

Su Lang sighed helplessly, taking a deep breath and slowly exhaling, then stored the Immortal Slayer Cannon back into his storage space.

The next moment.

Su Lang moved, arriving at the battlefield where Qian Zihou had fallen.

The battlefield had now become a massive sinkhole.

This sinkhole spanned tens of thousands of miles in diameter, was hundreds of miles deep, and its bottom was entirely composed of vitrified rock and fiery red flowing magma.

Furthermore, terrifying power of rules lingered everywhere within the sinkhole.

Martial artists below the Martial Saint level would face certain death if they stepped into it.

“Can’t pollute the environment, huh.”

Su Lang’s lips curled slightly, and while humming a tune, he pacified the power of rules in the battlefield.

Finally, he even dispatched clones to fill in the sinkhole, trying their best to erase any traces of the battle, lest the people from the Heaven Slaughter Tower guess his trump card, the Immortal Slayer Cannon.

Let the clones do the dirty work.

Su Lang moved and returned to the Sky Ocean.

Li Xianyang was also dispatched back at the same time.

It had to be said, Li Xianyang, this special clone, was truly useful.

“Master!”

Li Xianyang looked at Su Lang, his face filled with excitement.

After following Su Lang, he had quickly returned to the Martial God level in a short period, and he continuously mastered the power of rules.

Among the five fundamental rules of heaven and earth, he had already comprehended Metal, Fire, and Water, and also Lightning.

The Lightning rule was something Li Xianyang had never mastered before.

Besides his cultivation and the power of rules, what excited Li Xianyang even more was that Su Lang had actually brought out an immortal artifact he had never seen before.

The power of this immortal artifact was so immense that it could instantly kill a Martial Immortal!

“Alright, don’t look at me with such shining eyes, it’s annoying.”

Su Lang rolled his eyes, then ordered, “Go and tell everyone in the Sky Ocean to come out.”

“Yes!”

Li Xianyang immediately nodded.

Then he rushed into the Sky Ocean to inform everyone: “Yaochi Yanfa, Master commands all of you to come out, everyone must come out.”

Upon hearing the command, everyone’s expressions changed, revealing surprise.

Su Lang telling them to come out and no longer guard the Sky Ocean first meant that the threat from the Heaven Slaughter Tower had been lifted!

Secondly.

The last time Su Lang told them all to come out, the Sky Ocean was then promoted to an immortal artifact.

This time it was the same command.

Did that mean the Sky Ocean was going to evolve again!?

With excited and eager hearts, Yaochi Yanfa and the others, along with all the other guarding martial artists, withdrew from the Sky Ocean.

“Lord Xianyang!”

“May I ask if the people from the Heaven Slaughter Tower have already been dealt with by the Master?”

“What about the Martial Immortal from the Heaven Slaughter Tower? Did he escape?”

“……”
