Now that Lin Wu thought of it, he realized his action reminded him of something.

"Damn… I acted like one of them tentacle aliens didn't I?" Lin Wu shuddered.

He forcefully pushed that thought away and found the spot where he was supposed to dig through. He entered the ground and swiftly made his way to the area beneath the Royal library.

Unlike the Deer wood city, there weren't many underground places in the Capital city. He didn't know if they just didn't want to do that or if there were some other restrictions on making them.

He looked at the underground layers of the map and saw that only the buildings that belonged to the royals had an underground part to them. The rest of the buildings were all built on the surface and had more floors on them for space.

"Here we are," Lin Wu said upon reaching the underground wall of the basement. 

He used his spirit sense and found a suitable place to bore a hole through. The place he had chosen was right behind a large cupboard that was located in an empty room. Lin Wu created the hole easily and crawled out through the gap between the cupboard and the wall.

Though it was quite a squeeze and he ended up moving the cupboard a little forward. But after that, he would be able to easily re-enter when needed. 

"Is this a storeroom?" Lin Wu said, as he took a look around.

There was old broken furniture here that was covered with dust and cobwebs. It was evident that this room had not been opened for quite a while now. 

"Well… it just makes it more convenient for me…" Lin Wu said before going towards the door.

The door was obviously locked but all it took was a little effort from Lin Wu's end to open it. He looked at the keyhole and inserted a small spike into it. Then in it, the spike started growing and took shape of the interior.

~chink~

Lin Wu turned the spike and the door unlocked.

"Haha, lockpicking 100…" Lin Wu said before peeking out of the door.

The corridor was empty, but on the other end of it, a guard was standing. The guard was a cultivator and was dressed in different clothes than the city guards. These were the royal guards that served the royal family and consisted of only cultivators.

Lin Wu crawled closer and looked up at the beams going across the roof.

"Bingo!" He said to himself.

Lin Wu elongated his body and hooked on to a beam on the roof. He then pulled up his body and traveled ahead from one beam to the other. Him being able to extend and shrink his body made it a piece of cake for him.

But then Lin Wu's progress was halted when he got near the staircase. The guards here were scanning the area with their spirit sense. There were four guards here and each of them alternated between using their spirit sense. This way there was always someone alert.

Still, there was a small gap of a couple of seconds when they switched their turns. Besides, they didn't keep it focused on one place but instead moved it around just how a security camera would move.

"Hmm… aren't these people just glorified CCTV cameras?' Lin Wu thought to himself.

He waited for the guard to switch their turn and moved ahead at a lightning speed. Then when the spirit sense was about to pass over him, he shrunk his body and aligned it with the beam's length. The system also started masking his spirit Qi which made it harder to detect him.

Now unless the guard particularly paid attention to that beam, they wouldn't see Lin Wu there. Even then they would only feel that there was some inanimate object placed there. They weren't paying attention to a creature like Lin Wu, anyway.

What they were on guard about was humans or spies who may try to entire the library to steal things. Because of this, it became a bit easier for Lin Wu to sneak in. 

Every time they switched their turns, Lin Wu would move one beam ahead. There were many wooden beams that went across the roof, as they supported the weight of it. They were about a foot wide and several meters long, which made it more than enough for Lin Wu to hide.

It took Lin Wu about thirty minutes to cross the area before he reached the next floor. From here on, the progress was fast as there weren't guards constantly scanning with their spirit sense. 

About thirty more minutes later, he was at the entrance of the library. He had to stop here as the door was locked and there were four more guards standing there.

"Hmm… how do I go ahead from here?" Lin Wu wondered as he looked at the map.

The route shown on it was from here, and the other routes were even more risky. This was the only point of access that had the least amount of guards as well. 

It was now that he noticed the decorative wooden grill at the top of the doors of the library. The grill was there for ventilation and looked like one of those antique type ones. 

'Wait a minute… I can try that maybe…' Lin Wu thought to himself before getting closer.

He inched close to the grill carefully and made sure that the guards were not alerted. Finally, when he reached there, he studied the grill. He then brought his tail forward and turned it into a sharp form.

He then started to cut a part on the wooden grill slowly, making sure that no noise was made and no wooden shavings fell down. After a few minutes, an oval shaped hole with beautiful patterns on its edges was made on the grill. 

But Lin Wu was not yet. He created another similar oval shaped hole on the other side of the wooden grill too, making it look symmetrical.
