After checking the information for a few days, Lin Xu decided to go to several sewers where the accident occurred under Hoglald first.

It just so happened that the members of the Thestrals team were all from the Black Forest, and so was Sen Nan, so Lin Xu invited Sen Nan to go to the underground waterways to explore Grindelwald's secret room on their next date.

Mori Nan's reply was soon brought by the owl messenger.

"Uncle, how can there be a girl like you who still brings it to the sewer... Well, when? “

Lin Xu quickly replied to the letter.

……

The next day, in the afternoon, the two were in front of the academy's common room in the Black Forest, on the sewer square.

At this time, Lin Xu and Sen Nan were both dressed in black robes in the iconic style of the Black Forest. Sen Nan had already graduated from the Black Forest, and he couldn't know the password that was changed regularly inside the Black Forest in time, but he still asked a friend for the relevant password for this date, so that the two could explore more areas in the underground sewers.

Grindelwald's secret room has been open for more than half a year, but it is still not clear that anyone has obtained the inheritance of Grindelwald's secret room, but there are constantly basilisks in captivity in the secret room running out, many basilisks have ancient blood, with nightmare glimpse or petrified gaze and other terrifying abilities, but it has caused a lot of tragedy in the underground sewers.

The entrance to the underground sewer area is not only the entrance to the common room of the Black Forest, but there is no doubt that entering from here, along with the flow of people in the Black Forest, can explore more places without easily arousing the hostility of the people of the Black Forest.

Besides, Lin Xu also has a Sen Nan who has been here for four years, so he doesn't have to worry about getting lost.

The architectural style of the entire Black Forest adopts a large number of black bone styles and dark Gothic styles, and uses a large number of snake carvings, scorpion carvings and various legendary monster art products. Even the switches and valves of some of the water pipes in the sewer plaza are engraved with exquisite monster statues, showing the history of this building.

"Hey...... I've been here for four years, but the sewer is not a good place, and if it weren't for the elaborate reliefs on the walls, I wouldn't have been in the Black Forest at all. Sen Nan said with a little head.

"Nan, how did you spend four years in the Black Forest? I think you said that the Thestrals witnessed death and no longer feared it, and that you who came from the north and survived Hoglard were even more fearless. ”

“…… This time, Ben Shaman sacrificed himself to help you complete the task, so wait, I called my deacon friend in the Black Forest to bring something over. Sen Nan said.

After a while, a young druid man with pale hair and a shaman's robe walked in the distance.

The pale-haired young man looked at Sen Nan, and then at Lin Xu: "Ye Qi Nan, this is your newly recognized younger brother?" ”

Sen Nan sneered, but said happily: "Let him introduce himself." ”

"Lin Xu * Jing Lin, Sen Nan's friend." Lin Xu responded lightly, his eyes looked at the man, and he slightly revealed the mark of the runic pattern, indicating that he was also a shaman, and in Hoglald, the same rank had the same friendship.

"Fuji Hakusan, Sen Nan and I are both Holy Alliances from the north, and we have been relatively united over the years." Fuji Baishan also responded lightly, he turned his head to look at Sen Nan again, and threw a key to Sen Nan from his hand. "The key to the Black Forest, it would be useful to cross some roads in the sewers."

"Baishan, thank you so much. Liana and I will treat you to dinner another day. Sen Nan was full of surprise when he caught the key.

"Let's camp in a few days, let this friend of yours come over. Hezheer Deer has a lot of alliance geniuses this year, and it just happens to be able to find a topic with your friends. Fuji Baishan directly saw Lin Xu's identity as an academy and invited him at will.

"Aren't you afraid of your brother knowing about you?" Sen Nan said with a smile.

"He's so tender, he needs some reality to wake him up." Fuji Hakuyama responded lightly as before.

……

Subsequently, Lin Xu and Sen Nan started a journey of exploration of the sewer.

Now, more than half a year has passed since the opening of the Grindelwald secret room, and the various hidden areas of the sewer have been carpet searched in the past six months.

Grindelwald left a lot of writings and imprints on the Black Forest, and from Sen Nan's mouth, you can learn some about the legendary dark wizard in Hoglald's history. Sen Nan is a girl in the end, and she has been chattering about Grindelwald and Gargamel's gossip for a long time.

The exploration of the sewers took most of the day, Lin Xu and Sen Nan only encountered a medium-sized basilisk during the period, and the two of them solved it with a subtle cooperation, in addition to this expedition, there was no accident, but Lin Xu, summoned the ghost wolf and the winter snow wolf to escort him, and in a safer state of mind, he wantonly joked with Sen Nan.

That is, these days, the Red Moon Shadow Wolf that Lin Xu once left behind has also finished disposing of the corpses of Bimoth and others, and now Lin Xu can be summoned again and guarded around in case of accidents.

On the way to the expedition, Sen Nan invited Lin Xu to participate in the autumn festival camping of the druids in the Northern Alliance circle: "The autumn festival time in our north is generally earlier than that of the Violet Alliance, and the autumn festival dinner of the academy will wait for next month, so we will directly set up a camping camp in the secret realm of a thousand lakes in the stars and celebrate casually." ”

Autumn Festival, Christmas, New Year, and Easter are some of the most important festivals in this vast region. In addition to Christmas and New Year, the dates of the Autumn Festival and Easter vary from region to region. As one of the biggest festivals of the year, the main castle of Hoglard hosts a cross-house and even cross-year group dinner.

After Lin Xu entered the academy, he had always heard about the magnificence of Yingxing Lake and Yingxing Thousand Lakes Secret Realm, and now he had the opportunity to take a vacation with the opposite sex, and it was logical to accept it.

……

Another week passed.

Esmeralda successfully embraced Evan for the first time, and once brought Evan to visit the blood ancestor Lin Xu, and when they met, Esmeralda looked weak because of the use of the first embrace of the blood clan.

At the same time, Lin Xu's third runic structure, the Thorn Deer Crown, is also becoming more and more stable. Lin Xu is also getting closer and closer to the three-star druid.

Finally, it's time for the northern autumn festival camping mentioned by Fuji Hakusan.

On the side of the main castle of Hoglald, the whole lake is wide and beautiful, the lake water is clear, reflecting the stars in the sky, but it is like a star realm.

And since a long, long time ago, according to the Yingxing Lake, the half-plane constructed with folding space technology is also very beautiful.

Thousands of real and false star-reflecting lakes are all over this vast and boundless secret realm.
