After making up his mind, Nie Xuan began to circle the fortress. These black stones looked unusual at first glance. They could not be sunken with just a fireball technique. Moreover, the angle of the city wall was too steep. Even if it was sunken, he could not climb. After all, he was a layman in climbing. He could still climb up the two or three meters of earth slope, but the city wall that was nearly 90 degrees above ten meters was enough to save money.

What's more, even if he can climb up, it's useless. Because there are Drake Newt surveillance soldiers standing on the city wall with a bow and arrow every few meters, these surveillance soldiers will find him before he can start climbing the wall, so the bad idea of ​​climbing the city wall is absolutely not feasible.

However, the system cannot arrange tasks that will definitely fail, so Nie Xuan needs time to find loopholes in the defense of the fortress. At this time, he is also a little envious of assassins and thieves. If he had these two professions, it would be much easier to complete this task. What's the use of strict defense? If you use advanced stealth, you can get in with a big swagger. It's just a piece of cake. Unfortunately, he is not an assassin or thief, so he needs to think of his other way.

While running, he also took a lower-level speed reel. Now he is racing against time, so it is naturally good to run faster. Moreover, the speed reel did not disappoint him. The 10% acceleration effect is very obvious. It can be said that it is worth the money, but it is just running away. If it is a battle, the advantage will be even greater.

After about 10 minutes, Nie Xuan came to an end. The reason for the end was that this fortress was built between two cliffs. Judging from the terrain, it was indeed a good position that was easy to defend and difficult to attack. But the premise was that no one attacked from the mountain wall.

Although the cliff in front of Nie Xuan is steep, it is not as exaggerated as 90 degrees. There are also some footholds from time to time. These footholds are the tips for system setting. As long as you have courage and courage, you can climb up. Of course, this requires a little luck.

But Nie Xuan had a better way. These natural footholds were just simplifying the task for him. Even without these footholds, he was planning to use fireball techniques to blast out a way. With these natural footholds, combined with his fireball techniques, his safety factor could be greatly increased. As for what to do after going up, he could only take one step at a time. At least he should give it a try.

At 30 meters away from the city wall, Nie Xuan began to climb up. This distance not only ensured that the surveillance soldiers on the city wall would not notice him, but also made it easier for him to move from the air to the inside of the castle.

But after climbing more than 5 meters, Nie Xuan realized that he was a little arrogant. He used to climb a slope of more than 2 meters and felt that it was nothing, but it would be a big difference when looking down from the 5 meters above. Although he is not afraid of heights, as long as he is a normal person, he will feel guilty when facing high altitudes. This is a very normal phenomenon.

Moreover, the difficulty of climbing this kind of mountain wall is far beyond his expectations. It seems quite simple, but it is not the case after coming up. Every time you rise by 1 meter, you have to think carefully. You have to observe, plan the route, and pay attention to the coordination and stability of your body in terms of details. There is also food problem. When doing this physical work, Nie Xuan's physical strength drops very quickly, at least 5 times faster than usual. Of course, this is not unrelated to his poor physical points. Although the extreme wisdom attribute brings him high magic damage and super high magic value, it makes him lag behind others in other attributes. If someone else climbs this hill, his physical strength will not decline so quickly like him. He doesn't bring much food, so if he wants to continue this task, he must enter the fortress as soon as possible to reduce the rapid loss of physical strength, otherwise even if he is not killed by the monster, he will die due to exhaustion of physical strength.

Another point is that he has no safety measures. If he fails, he may lose his life. Now he may not be able to die of 5 meters high, but it is difficult to say that he will climb a few more meters. Since the fortress is more than ten meters high, Nie Xuan must also climb to that height, wait until it is equal to the fortress height before moving there, and then wait for an opportunity to enter the interior of the fortress.

As the height became higher and higher, Nie Xuan's climbing speed gradually slowed down. He no longer had time to worry about physical strength. That was the future. It was more reliable to save his life first. As his height reached 10 meters, the mountain walls were not easy to climb, and the system set fewer and fewer footing points. He had to use fireball to blow out a temporary footing point. But even if he could silently recite the fireball technique, he needed one hand to make magic gestures, so he had to ensure that he could not fall down, and he had to free up one hand to release the spell, which was very challenging for him. There were several times when he almost fell down. If the fireball technique was not interrupted at the critical moment, he would hold it firmly, then Nie Xuan had already replied to the resurrection point report.

Compared to climbing, the difficulty of moving horizontally is slightly lower. Nie Xuan is barely competent, but he must be careful. After all, his height has reached the height of the fortress at this time, and it will definitely be fatal to fall down.

The Dragon Clan Gate may think that there is no enemy attack here on the mountain walls on both sides, so the surveillance soldiers here are much sparse, at least you don’t have to worry about chain hatred. Generally speaking, this group creature will summon comrades when there is not much blood. This move is not a skill, but their instinct, and the range is very large. Icefoot will use this move, but they pull the Icefoot outside the village to kill, so the pressure is not great. But if they are shouted out by this Drag Newt, then Nie Xuan will probably run away in vain this time. No matter how strong he is, there is a limit. A group of level 30 dragon monsters are definitely not something he can deal with. Even if he wants to use push building blocks, it is not possible, because the city wall is too narrow and there is no such terrain conditions at all.

Fortunately, the surveillance soldier closest to him did not focus on the mountain wall. He was far away from the mountain wall and could not find him immediately after Nie Xuan jumped to the city wall, which gave Nie Xuan a chance.

After he gently descended to the city wall, Nie Xuan stood close to the mountain wall and was in the corner, and his figure was completely hidden in a shadow. Although he did not have invisible skills, hiding this way can reduce his chance of being discovered.
