Jiang Wuwei and Sister Shuangjiao were in the reference room of a small town library called Zell when they consulted the architectural structure of the Peninsula Castle.

Tianjiao skillfully operates the computer and processes the data quickly. Wu Wei looked at the sisters who cooperated tacitly, smiled and whispered: "I didn't expect the two senior sisters to be so professional and about to catch up with professional spies." ”

Tianjiao's eyes were glued to the computer screen, and she said intently: "The drawings can be reproduced in three-dimensional form, which is very helpful for our next move." ”

Jiang Wuwei has been in contact with Shuangjiao for more than half a year since he first met Shuangjiao, but the actual contact time with the two sisters is very small, except for joining forces with Tianjiao to defeat the Desert Eagle, knowing that their gambling skills are superb, he really doesn't know anything else. Just now, I saw Tianjiao conversing with the librarian proficiently in German, and now she is so proficient in computer software, which makes Jiang Wuwei ashamed.

"Do you think they're going to renovate the castle?" asked Tianjiao, looking at the yellowed drawings.

"I think since they use this as a lair, they will definitely renovate the castle, at least install some security protection facilities and monitoring equipment, but the overall structure of the castle will not change much, such as here. Tianjiao stopped operating the keyboard and pointed to the display screen to show Wuwei at this.

"All ancient castles have a common feature, they have complex underground structures underneath, such as basements and underground passages, and this peninsula castle is no exception, with many underground passages that extend in all directions. “

Jiang Wuwei followed Tianjiao's fingers and saw that there were several criss-crossing passages on the drawings, and he thought it was a corridor if he didn't pay attention to it.

"These underground passages are used to fight against the attacking enemy, so that they can move inside the castle, and some are used for escape...... "Tianjiao introduced to Jiang Wuwei while operating.

Jiang Wuwei suddenly had a thought in his heart when he heard this, and he hurriedly asked: "The underground tunnel used by the owner of the castle as an escape must lead to the outside, you check if this castle has such a tunnel." ”

"No problem. Tianjiao then said to Xiaojiao next to her: "You first look for the drawings of the underground structure of the castle and check if there is any leading to the outside of the castle." ”

Soon Xiaojiao handed a stack of drawings to Tianjiao, "I found it, this one should be." ”

Tianjiao took it and examined it carefully, and then said to Jiang Wuwei: "There is indeed such an underground tunnel. ”

"Where is the exit of the tunnel?" Wu Wei hurriedly asked.

"It seems to lead to Lake Constance, so it's best to go to the field. ”

Jiang Wuwei pondered for a while, and said to himself, "I wonder if I can enter the ancient castle through this tunnel?"

Of course, Shuangjiao understood Jiang Wuwei's plan, and Tianjiao said softly: "Let's hurry up and finish it, and then let's go to the lake to look for it according to the drawings and see if we can find the exit." ”

An hour later, Shuangjiao copied all the drawings of the castle to the computer, then returned the materials to the administrator, and thanked the administrator repeatedly before leaving the library.

The Shuangjiao sisters have been in the town for a few days, and they are already very familiar with this place, and after getting in the car, Xiaojiao drove directly to a motel in the town, opened two rooms, and settled down first. What is to be done later must be done in secret, and the car needs to be put here.

The three of them couldn't wait to get out of the hotel before they had time to rest, and the town often had travelers like them, so their actions didn't go unnoticed.

After leaving the town, they walked through the woods to the edge of Bo Lake, where the clear water could see the green aquatic plants at the bottom of the lake, and the fish shuttled among the fluttering aquatic plants, and some people disappeared without a trace.

Tianjiao opened her laptop, and then began to look along the lakeside, and after they walked a distance in the direction of the castle, Tianjiao stopped, she checked her surroundings, and then said to Jiang Wuwei: "According to the drawings, the exit of the tunnel should be near here." ”

Jiang Wuwei noticed that the terrain here was obviously much higher than the place they had just come over, and a few meters away from the shore of the lake was a forest, with thick trees with lush branches and leaves, all of which were more than a hundred years old.

Jiang Wuwei took the telescope from Xiaojiao's hand and said to the sisters, "You wait a minute, I'll climb up the tree and observe." Then he came to the foot of a tall spruce tree, clinging to the trunk with both hands, and with a few slaps of his feet, he sprang up. Climbing trees is a very easy thing for Wuwei, when he was a child, the big trees around the barracks were not as good as he couldn't climb, and those trees were mostly imported eucalyptus trees with smooth bark and tall trunks, which were much more difficult to climb than this.

More than ten meters above the ground, Jiang Wuwei saw the spire of the tower in the castle from the gap in the branches and leaves, about two hundred meters away from them, he climbed up a few meters more, and then observed it with a telescope for a while.

Jiang Wuwei walked to the lake after coming down from the tree, standing on a rock on the shore to inspect the situation of the lake, the lake here is obviously deeper than other places, and the lake water is black and oily to the bottom. He turned back to Tianjiao and said, "The exit of the tunnel should be nearby, I guess it is the most likely to be in the water." ”

Tianjiao also agrees with Wuwei's opinion, because the ground in this area is mostly rocky, and the lake is relatively deep, so it is not easy to be found by hiding the outlet in the water.

"Shall we get a set of diving equipment and go down and have a look?" Xiaojiao asked the two of them.

"It's a little late today, I think let's go back to the town first, and come over directly tomorrow morning with diving tools, what do you think of Brother Wuwei?" Tianjiao asked for Wuwei's opinion.

Jiang Wuwei thought that if he returned to the town to get diving tools and then returned, it would be dark, so he nodded in agreement with Tianjiao's thoughts, "Okay, after a day of running, everyone is tired, go back and rest for a night, and come back tomorrow." ”
