There are not many cities like Fuyuki City, which are divided in half by river water, so the drainage system is different from that of ordinary cities.

Many people may have noticed that there is a large drainage ditch under the riverbank, but absolutely no one could have imagined that something inhuman was hiding in it.

"It's a spacious and secluded nest, and although I don't have a serious magician's background, I can think of building a workshop here as a wise decision."

Ling Yi and Karna are currently inside the sewers, and they are still going deeper.

It was just after noon.

There is no light source here, so you can only rely on the flashlight you carry.

Even so, with Karna following him, coupled with the fact that the opponent's strength was really not good, Ling Yi was not very worried about whether he would suddenly encounter the enemy, but instead looked forward to the opponent jumping out of the battle quickly.

That way he wouldn't have to stay in this foul-smelling environment.

"Lancer, do you feel the other person's breath?" Ling Yi was quite puzzled in his heart, after all, it was the workshop that had just been decided, how could there be no movement at all, shouldn't he be busy with construction? Or rather, in a deeper position.

"Not yet, but your judgment is right, there is indeed a remnant of the Servant's breath here, and it is obviously not as simple as coming once or twice." Hearing this, Karna, who had remained spiritual, gave a confirmatory answer.

It's good, it seems that the other party didn't notice it, and thought that this was a foolproof secret stronghold.

This will allow you to take a surprise by surprise.

"I'll give you a signal later, don't care about the consumption of mana, and suppress them in one go." Ling Yi ordered that the other party was not good at hand-to-hand combat, so there was no need to spare his hands and disarm them in one go.

"Understood." Karna nodded.

The length of this gutter is about 300 meters, and about five minutes have passed since it came in.

Finally, they came to a wide space. It's still dark, and the air doesn't seem to be moving. But there is no sense of oppression in a narrow space.

Wait, there's a light source

Not far ahead, there was a slight light between several thick water tanks, and even the sound of laughter and flickering shadows could be heard.

Ling Yi immediately held his breath, waited for a while, and made a 'up' gesture.

So, Karna went into action.

Of course, this was invisible in Ling Yi's eyes, and no one knew how fast Karna would be after the spirit transformation, but the wail and a heavy muffled sound came from the next second, indicating that the other party was knocked down before he had time to react.

So to speak—

"Caster isn't there?" Ling Yi glanced at the red-haired young man who had fallen to the ground unconscious, and immediately frowned.

"Yes, I've looked it all in, but I haven't found Caster."

Karna said solemnly.

What a stroke of luck.

Ling Yi glanced around, except for a glowing crystal ball, it was cold to be empty.

Oh forget, and the red-haired youth on the ground.

"I think Caster probably went out on the spur of the moment. Master, should we wait for him here? ”

"Of course. How can he come and return empty-handed, not to mention that this guy is his master, and it is impossible to leave him alone. As for weishenme not being here, you guessed it right. Although Ling Yi was smiling, his eyes became more and more solemn.

Something temporary? That guy's 'thing' is really unpleasant.

in every sense.

In short, waiting is a long and patient process.

Ling Yi sat on the ground with the crystal ball in his arms, and his eyes fell on the picture displayed by the crystal ball, but this showed that it was neither someone taking a bath nor a sports competition, but some street scenes, which was even more boring than watching a third-rate Korean drama.

He wasn't worried about Caster's sudden return, because Karna was guarding the entrance, almost perfectly hiding his aura and body, as long as he didn't make close contact, he would never be able to find it, and Caster would be attacked by Karna for a while after he returned.

The unsuspecting magician faces the spearmen who are ready to attack, and the result is doomed.

Even in the Throne of the Immortal, Karna, who is considered a top spearman, if he can't even take a half-magician, then he will be too sorry for the reputation of the son of the sun god and the great hero of the demigods.

"Speaking of which, what should this guy do" Ling Yi suddenly thought of Yusheng Ryunosuke, the unlucky red-haired youth, and couldn't help pinching his chin in thought.

It was okay to kill him after depriving him of the curse, but he always felt that there should be some tactical value.

It's a bit of a waste for such a murderous genius to easily inspire a sense of justice in others.

"Inducement or deception?" Ling Yi tried hard to recall the tactical theories he had studied, generally speaking, no matter what kind of war there is, there are common points, so some tactics are very common.

For example, the two that Ling Yizheng pondered, one could use Yusheng Ryunosuke to make the enemy think that it was the Master, and then induce the other party to make a wrong judgment. It's similar to deception, but there are differences.

If you choose the deception tactic, it is to let Yusheng Ryunosuke take Karna to form an alliance with the enemy, and then find an opportunity to stab behind his back, but the other party is not a fool, so even if Zuihou succeeds, Yusheng Ryunosuke's survival rate is not more than 30%.

Just when Ling Yi was thinking about the pros and cons.

-- A mutation has occurred

The right word to describe it is - explosion.

Yes, the flames, ignited by the flames of the blazing gunpowder, suddenly set off a big explosion.

The location was at the entrance of this spacious space, very close to Ling Yi's location.

A few seconds after the explosion, a violent air flow whistled.

Ling Yi dodged to the back of a water storage tank in time, where was the dead corner of the wind.

"This magic is Karna?" There was a feeling of exhaustion of mana in his body, and Ling Yi was a little dumbfounded, wasn't it just to pack up a Caster, as for making such a big move?

This physical destructive power is more than Class A.

Placed on the ground, this is the destructive power that can directly blow up a building

And this was just to deal with Caster, who was extremely 'weak' in Ling Yi's eyes.

After a while, the airflow gradually stabilized.

This is an unventilated place, and even an explosion of this magnitude will not affect the ground.

When the aftermath completely subsided, as soon as Ling Yi turned on the flashlight, Karna walked over.

What caught Ling Yi's attention was that he was still carrying a humanoid object in his hand.

"I'm sorry, Master, this guy is very vigilant, and seems to have spotted traces of an enemy invasion and is about to retreat, so I had to intercept him with 'magic release'.

As he spoke, Karna let go of the humanoid object in his hand.

"No, it's okay, just complete the task." Ling Yi didn't care much about this, but more about the Caster on the ground, which was no different from humanoid coke.

It seems to be miserable
