Establishing a special teleportation array is a major event in the system. After establishing a city, you can freely build a teleportation array. However, if you do not establish a city, you need to build a teleportation array in your life skills to practice the formation or Qimen Dunjia technique to the master level, and you also need to obtain the array diagram and necessary items.

The formations practiced are not the same as those of the Qimen Dunjia. Players who practice formations must have a formation map to build various magic arrays, including teleportation arrays, and the large protective magic arrays in the system city are also formations. Although there are fewer and extremely difficult to upgrade the formation players, there are still players practicing them.

The masters who practice Qimen Dunjia are often masters who are proficient in this kind of metaphysics in reality, otherwise they would not be able to complete very difficult tasks given by the system. Therefore, they can draw a formation diagram by observing the principles of the formation, and then make it. The master of Canghai Sect is a genius who practices Qimen Dunjia. He is currently a master-level figure in Qimen Dunjia. He can be promoted to the master as long as he works hard to complete a few tasks in one go.

Of course, after Ye Yutian learned that the establishment of the teleportation array required complicated conditions, he became suspicious of the original establishment of Canghai City. Establishing the teleportation array in the field in advance would have the ability to establish the teleportation array in other places. This has very good prerequisites for military operations. It seems that there are many people with key forces in the system, so you still have to pay attention to it carefully.

It is not particularly difficult to open the teleportation point. Killing monsters is just like a common occurrence for Ye Yutian, but the whole process is very troublesome. The Jiuyou Demon Clan has a lower base outside Xiangyang City. What Ye Yutian needs to do is to flatten the big guys in this base, and then kill ten thousand monsters that were invaded by the demonic energy. The key is that this "Kongming Stone" is difficult to find.

The query system was of no help, and "Kong Mingshi" had no clue. Ye Yutian immediately asked his players to pay attention to the news about "Kong Mingshi". In addition, the stores of Lin Xue's affiliated chamber of commerce in major cities also began to look for clues about "Kong Mingshi", but the results were still not optimistic.

Not no one in the system made "kongjing stone", but these items that do not know their purpose cannot be sold at any price. If the price is too low, it will make these players feel uncomfortable, so most people throw this stone into the corner of the box.

Now Ye Yutian dares and cannot buy "Kongmingshi" with great fanfare. There are so many hostile forces in the system that are not against him, so it is possible to deal with him in this matter, and even prevent him from purchasing "Kongmingshi".

Therefore, Ye Yutian put the breakthrough on Xu Tianhao. Since they could establish a field teleportation array, it is inevitable to know the whereabouts of "Kong Mingshi". The two sides are still in the cooperation stage for the time being. At least there is a breakthrough. On the other hand, Feng Kuang needs to work hard in the thief union to find ways to collect intelligence. When encountering these special items, Ye Yutian found that it was still an NPC force or more reliable.

After dealing with all aspects of the situation, Ye Yutian organized hundreds of his players to move towards the designated location. Along the way, spies from all walks of life were inevitably observing the dark night. Ye Yutian didn't care about these followers, and began to search near the coordinates given by the lord of Xiangyang. On the other hand, the players gathered together sweep the nearby monsters and complete the number of 10,000 monsters as soon as possible.

The tasks related to gangs are convenient. You can use a large amount of human resources from gangs. It is much simpler to complete than most tasks, but it is also difficult to do many confidentiality work.

After sweeping in a ten-mile radius near the designated location, a player discovered a dark cave hidden under a hill, which seemed to be the stronghold of the demons. Ye Yutian immediately went in with a few friends, among which there was a professional thief Xiaohong singing in front of him.

The demons’ caves are built like underground tunnels to facilitate the movements of monsters and human-shaped demons. They are more than two meters high and can allow three or two people to enter in parallel. The only disadvantage is that they do not have lighting facilities.

After Ye Yutian first entered the cave below, he felt that the air circulation was still very convenient, but a special aura was faintly suppressing everyone's bodies. Xiaohong sang in a low voice: "This demon stronghold should have the demon altar mentioned in the forum. It can release the demonic energy from the abyss to invade the monsters. In addition, players may come here to accept the task of changing jobs to demons, which may not be so easy to deal with.

Especially in Xiangyang City, which old man asked us to destroy the altar, you should know that each altar will have a demon general who guards the altar and a demon priest. These are two big monsters of level 70!" Tiandi Yisan and the dog catching rat took a deep breath and said, "So there are two small bosses of level 70 here. Then we still have some fights, as long as you are careful, there should be no problem!"

Ye Yutian nodded, and Shui Banzhu said behind him: "This time we have officially organized a powerful team for the first time to explore. I'm afraid there will be many opportunities to face the ruins and underground mazes in the future. It's better for us to get familiar with it first!"

After instructing the three hundred dark night players outside to surround the demon's cave in a circle to prevent other players from entering and causing trouble, Ye Yutian and his party immediately went deep into it. Xiaohong sang softly in front of him, followed by the little ants hiding himself in the shadow under the wall and slowly moving. The group carefully did not ignite the torch, but released the magic of "bright eyes" from half a bucket of water to give everyone some vision in the dark, but the range was not large, and they could only see dozens of steps in front of them.

Fortunately, the thieves have night vision bonus, which is very convenient for the two thieves to open the way forward.

The two of them are not very good at playing the game. Xiaohong's low-singing mainly develops skills in listening, exploring terrain, and removing traps. Her steps are extremely light, while the little ant is mainly good at fighting, with assassin killers as the development direction. The ability of these thieves is still a little worse. However, he has successfully taken office as a shadow killer and his combat power in the dark is second only to Ye Yutian, and is stronger than several demons.

Xiaohong sang in front of her and walked successfully, several traps had been successfully lifted. Everyone was frightened from behind. The wise NPC was much harder to deal with than monsters. If they didn't lead the thief to open the way in front, they might consume most of the energy of everyone, and they might lose their lives here if they were not careful.

The traps in the passage not only include normal horse pits, ordinary traps such as arrow alleys, but also many trigger-type spell traps. Xiaohong sang softly, even a first-class thief, and was still stumbled when he was lifting a trap. He was struck by the lightning triggered in the trap. Fortunately, Ye Yu Tianjiling rushed forward and grabbed Xiaohong and sang softly, helping him absorb some of the lightning attacks. Otherwise, the thief would have explained here today. "Damn it, no wonder so many thieves on the system forum suffered losses in these Nine Demon Caves. The traps here are all master-level levels. If you accidentally kill someone, you will be dead. It's so bad!"

Ye Yutian whispered softly: "Is it because we received the task that the system has strengthened the defense conditions here? You should know that the system will increase the difficulty of the game based on the interaction between various tasks. But you were too careless. Fortunately, I am here today. If you were in a special map, if you hang up our task, it would be almost the same as failure!"

Xiaohong sang softly and said, "Boss, this time it was an accident. At first, I didn't expect the trap here to be so exaggerated. Now I'm careful, so naturally there is no problem. I also got a good tool for dismantling the trap from Old Man Zhuge. I will definitely be careful this time. Don't get too close. Thieves have a certain damage-free effect on the damage of the trap. If you come together, the losses will become greater."

Everyone nodded, and the two demons followed Xiaohong and moved forward quickly. Water Banzhu beat Ye Yutian in the middle, while the little ant was hiding in the shadow of the mountain wall, exploring carefully.

The tunnel of this cave has been sloping slightly downward. When it reaches a certain level, it will be connected with the underground world. It is completely like entering another world. After Ye Yutian and his men entered the underground world, they looked at the tall mountain walls around them, and it felt like they were in a huge valley where the sky was dark. The mountain walls were covered with huge moss and some unknown plants, all with a faint green fluorescence in the darkness. It took everyone a while to adapt to it, looking at the vast world, there were mountains, stones, and the sound of flowing water coming from afar, which told everyone that this was a special underground world.

Several people looked at each other, but Ye Yutian smiled bitterly: "We have a great fortune. This is not an ordinary task. It is actually a task connected to the underground world. Maybe we can still enter the abyss underground!"

Shui Bantong looked around carefully and said, "It's a bit strange. Is it because the Jiuyou Demon Sect in Xiangyang has been opened? According to my thoughts, the Jiuzhou in the world should each correspond to a Demon Sect. If this is the underground world after the Demon Sect is opened, then we are probably not as simple as a demon altar. It may still be a demon city, and it may even be a demon army!"

Ye Yutian pondered for a moment and said, "No matter what the situation is here, the reason why the system has just been updated, or because the demon altar has opened the underground portal, in short, we have to see the situation clearly at any time. Everyone should take action soon, so that people who are not disturbed here can obtain information, and then go back to settle the score with the old man in Xiangyang City."

Everyone nodded and explored forward. Ye Yutian guessed well, because the addition of demon players, his understanding of the ground world is much more than NPCs imagined. The demons obtained a lot of ground intelligence, and with the help of the players, they established forward strongholds in various places as soon as possible, opening the prelude to the war, because under normal circumstances, the demons could not leave the underground world, and the light would bring huge damage to those players who had just become demons, so the demon players were well controlled.

More importantly, the NPCs of the Demon Clan did not trust the players so much, but secretly presided over the army from all over the country to enter the Jiuyou Demon Sect after it was opened, and opened up channels in various places by secretly establishing altars in various places. This time, Ye Yutian and the others were lucky and discovered that the forward base of the Demon Clan was connected with the underground world, which in itself has a great development.

The group moved forward carefully and did not encounter many demons. Occasionally, some uneasy monsters could end quickly under Ye Yutian's strong bow and several masters' attacks as fast as lightning. However, Ye Yutian's letter sank to the bottom of the valley. There should be demons here, so after walking for so long, I haven't encountered one, so where are they all?

There are also master-level traps that not everyone can do. Why is it for such a large amount of capital?

A dark platform suddenly appeared in front of Ye Yutian in the distance. The shape similar to the Temple of Heaven and the four dark aids around it all showed that this was the altar of the demon clan, but there was not even a figure nearby, which made people feel very strange.

Xiaohong waved his hand and quietly lurked over to explore the surroundings. The little ants hid in the shadows around, protecting Xiaohong's sang forward, and also began to reconnaise the surroundings. The thieves had reconnaissance techniques to find out whether there were other traces around, but how to judge was still up to the players themselves.

After the two of them passed quietly, they still lurked back quietly. Ye Yutian and others hid on the huge stalactite pillar and listened to their reports.

"Boss, it's very strange. The footprints around us are very messy. Many people probably have moved here, but they immediately moved deeper down. There are no people around here at all, but it is indeed the altar we are looking for. This situation is a bit strange!"

Xiaohong sang inexplicably authentically.

The little ant added: "It turned out that there should be about fifty people stationed here, and there were traces of huge creatures like mounts moving. Later, about dozens of people's footprints appeared, but these footprints came from all directions and gathered and walked in that direction."
