In the past three years, in addition to cultivating magic, doing hunter tasks, and discussing magic with Mo Fan Xinxia, Beitang Yu still has tasks to do.

In three years, Beitang Yu's magic power has increased a lot, but the improvement is not too strong, although the five series of initiates have the five spirit beads and the five elements of the concept, but in the absence of any chance, the speed is always very slow.

And in terms of ninjutsu, Beitang Yu has not fallen, and he will find time to practice ninjutsu every day, so that ninjutsu has become more exquisite, especially the cultivation of immortal arts.

Only the seed ability and the ghost ability have not been improved much, and there is no life-and-death fight and crazy killing, and it is really difficult to improve these two abilities.

And the information collected in the past three years, under the collation of the white queen, there are already some clues, and the Black Holy See is really good at hiding, so hidden that Beitang Yu has not been able to find out their existence until now.

But through some scattered information from the Hunter Guild, Beitang Yu discovered a situation, that is, the underground waterways were actually dug out by the giant-eyed fishy rats for various large and small passages, and these passages made Bai Hou a lot of suspicion.

Bai Hou speculated that if these passages were connected to outside Bo City, it would be easy for the demons outside Bo City to easily enter Bo City and bloom in the center.

Although demons are not controlled by humans, who can guarantee that the Black Sect has the ability to control demons? Even if it does not have the ability to control demons, it is still possible to attract monsters, right?

Thinking of this, Beitang Yu naturally had doubts, after all, there are a lot of big passages dug through, all of which are distributed in several important areas of Bo City, if you don't explore, Bei Tang Yu is not at ease, after all, if you really want to let the demons enter Bo City from these big passages, then it will not be easy to deal with them at that time.

In this case, Beitang Yu did not inform Captain Xu and the others, but just asked for leave with Captain Xu and the others for a period of time to deal with their own affairs.

The strength of the Black Sect is too strong, and these members of the Demon Hunting Team are all beginner-level mages, so it is definitely not possible to deal with them, so Beitang Yu naturally wants to go into battle in person.

And for this matter, Beitang Yu didn't even care about Mo Fan's graduation, I heard that he had a duel, but where did Bei Tangyu have the heart to see it.

On this day, Beitang Yu entered the underground at a sewer near Xinxia School, and through the exploration of the ghost eye, Beitang Yu quickly entered this huge passage, recording the situation of these passages along this passage.

"It seems that there is really a big artificial component. Beitang Yu said.

"Yes, sir, based on the information we've gathered about demons, they don't do anything like tunnel warfare. Bai Hou said.

Although these are all passages dug out by the Giant-eyed Fishy Rat, Beitang Yu knows that there is a summoning system among the mages, so it is not surprising that someone has a summoner like the Giant-Eyed Fishy Rat, and the Black Sect is hiding so mysteriously, and it has not been able to find a single person in Bo City for three years, which naturally makes Bei Tangyu suspicious.

Records along the way, Beitang Yu killed a lot of giant-eyed rats who wanted to sneak attack in the dark, in the darkness of the underground passage, the giant-eyed rats can be said to have a great advantage, and ordinary beginner mages must be suppressed by giant-eyed rats here.

But Beitang Yu's ghost eyes have an advantage over the Giant Eye Fishy Rat, and along the way, the Giant Eye Fishy Mouse may not have discovered Beitang Yu, and Beitang Yu has already killed them one by one.

Traveling a long way, Beitang Yu recorded a lot of routes, and although some places were connected, the main trunk was directly connected to the demon clan outside the city.

As soon as Beitang Yu approached the exit, he found two people guarding outside the passage.

"People from the Black Church?"

After discovering this situation, Beitang Yu naturally made a decisive move, the two middle-level mages were nothing in Beitang Yu's eyes, the power of magic was very strong, but the sneak attack of ninjutsu was even more domineering, and the two middle-level mages were knocked out by Beitang Yu without reacting to what the situation was.

Beitang Yu grabbed a mid-level mage, and then began to torture him using the Soul Transfer Dafa.

"It would be nice if there were a human puppet, just draw your soul and read the memory. Beitang Yu thought to himself.

In this world, Beitang Yu really can't find any good materials to make six puppets, even if the military commander of Bocheng is just a high-level mage, Beitang Yu doesn't even look at it.

And the Soul Shifting Dafa has a lot of flaws, especially for guys with extremely high spiritual power like mages, their resistance is very strong.

"Huh?"

Beitang Yu suddenly let go and took two steps back, the middle-level mage who had been cast by Bei Tangyu on the Soul Shifting Dafa suddenly convulsed, and Beitang Yu felt a dark power appear in their bodies, and it disappeared in less than a moment, accompanied by the death of this middle-level mage.

"What kind of magic is this?" Beitang Yu didn't come up with the result, but he also knew that it must be the power of magic, but it was a situation that he didn't know.

The beginner level magic belongs to the elemental class, and after the middle level, other types or still elemental classes will appear, and Beitang Yu, who is only mixed in the Hunter Guild, has not explored too much in terms of magic types.

"Try this. "Beitang Yu didn't use the Nine Yin True Scripture's soul transfer Dafa this time, and there is no way to explore the innate internal force, so he used the eye of fear to suppress that dark power with ghost energy.

The power of fear of the gluttonous eye and the invasion of the ghost qi caused the second middle-level mage mage to react violently, although Beitang Yu reacted quickly and used the ghost energy to erode the dark power, but the result still made the middle-level mage die violently.

"Amazing, it's not unreasonable for the Black Holy See to be able to hide such a thing in his own person. Beitang Yu thought to himself.

At this moment, Beitang Yu really began to pay attention to this Black Holy See, although he was not able to get useful information this time, but at least he found that these passages were related to the Black Holy See.

As long as it is not a second goods, then it can also be seen that the Black Holy See wants to use demons to enter Bo City from underground and destroy Bo City in one fell swoop.

Kitado Yu searched the surroundings and returned to the passage after confirming that there was no one else.

This time, Beitang Yu began to wreak havoc, and the passage was collapsed, and it collapsed completely, causing some of the ground in Bo City to collapse, causing a great shock to the top of Bo City.

And after Beitang Yu completed all this, he quietly returned home, quietly waiting for the appearance of the Black Holy See.

Destroying such a big conspiracy of the Black Holy See, Bei Tang Yu estimated that the Black Holy See would definitely look for him everywhere, and he might even attack directly in anger.
