The bloody assassin who sneaked up just now was not a wild monster, but a subordinate class of the hero with the master, which made Long Zehao and Menglan temporarily stop their progress, and sent a reconnaissance class while making a vigilance.

At the same time, Long Zehao was still thinking about the sneak attack just now, the sneak attack of the bloody assassin of the Drow Elves just now made Long Zehao sure of one thing, that is, his intuitive perception ability was still flawed, and he couldn't react in advance in the face of the sneak attack of the superb assassin.

In the face of the sneak attack of the bloody assassin just now, he didn't have a sense of danger until the moment the other party made a move, just because of the environment of the underground world, as well as the low-level strength of the wild monsters and aboriginal heroes he encountered along the way, in a relaxed mood, his response was a beat slower.

These bloody assassins do not have the slightest murderous aura before attacking, and even lurk are extremely careful, and avoid anything that can attract the attention of the target to the greatest extent, including not staring at the target for a long time, not using high-powered ordinary magic items, and restraining all mental fluctuations before attacking.

Long Zehao praised in his heart: Sure enough, it is a rare class unique to the Drow Elf Clan, just after underestimating this underground world, they came to give him this slap. Let him know that there is a sky outside the sky, there are people outside the world, and no ability can dominate the world, not even his extraordinary intuition of his new special ability.

After making preparations, Meng Lan took out the simple map, looked at the map and said thoughtfully: "This city is a key node in the layout of the entire formation, let me take a look, plus the Tianquan, Streamer, Ziyao ...... in front."

As he spoke, Meng Lan took out another pen and paper to draw there, and from time to time added some locations that had not yet been detected on the copied map, and made some conjectures there: "Anlina Starry Sky Spirit Gathering Array, the formation arranged here is this, but the formation arranged now has been varied and improved, and now there are still some key variables, and it is impossible to see the key face of the formation." ”

When Meng Lan was there to deduce the formation, Long Zehao also got a little simple information from the scout class, this is a city of drow elves, and before all the scout classes died, the information he got had already shown that this was not something that the two of them could attack.

This city is the largest city Long Zehao has ever seen in the underground world, and it is basically comparable to the small cities in the surface world, the real kind of city, not the kind that shows that the city is actually just a village.

The city has a large number of functional buildings, a well-developed class recruitment camp, and a large number of Native heroes.

Before entering the city, all the troops who had been scouted in the past had all been killed, and the whole city was roughly trapezoidal, and the shortest wall was more than a kilometer long, on which were stationed two drow elven heroes, one minotaur hero, and four caveman heroes.

The Drow Elves and Minotaur heroes are both third-order existences, while the cave people are second-order, and depending on the situation, they should be used as cannon fodder to block and consume the enemy.

The other three city walls are also in a similar state, and they don't know what the state of the city is, in the face of the enemy's professional assassin troops, none of the reconnaissance troops sent by Long Zehao have the ability to enter this city of drow elves.

Thinking of the fourth-order troops that came to assassinate them just now, then there are at least fourth-order enemies in the city.

After Menglan deduced several possible variant formations, Long Zehao selected one of them after watching it, and the two chose to bypass this elven city.

During the break, Long Zehao looked at the news and intelligence from the outside world: "I don't know who got this formation mage who shrouded the entire underground world." Even the attention of the school teachers was attracted. ”

The number of resources in the underground world is scarce, and the quality is not very high, if there is no news, the teachers who know the school are also paying attention to this underground world, and the teachers who cannot enter the Tyranid world for the reason of rank have personally released a large number of private tasks to the students.

Guessing what secrets were hidden in this underground world, Long Zehao continued to break the formation here, as if it was possible to intervene.

Long Zehao has long chosen to leave this underground world, not all the new unknown regions have great gains, especially this kind of world where the weak are too weak, the strong are too strong, and all the aboriginal forces are in a hostile state at the beginning.

Of course, if you can investigate the reasons why the indigenous forces of this underground world are hostile from the beginning, it should be a good gain.

However, in the face of this uncertain situation, in the face of the fact that the surface world can harvest contribution points related to the advancement of the Tyranid world, it is easy to understand which one to choose.

Now staying in this underground world, it is because the school teachers have offered a reward that people can't refuse, as the first person to enter the underground world, the information in their hands has been exchanged for a lot of resources.

In the known, including the foreseeable, they still belong to the first group, as long as they continue to stay in the lead, the new discoveries are basically first-hand information, and they can be exchanged for resources from the teacher.

In particular, some teachers' personal skills, skills, and unique resources, which are usually not thought about, are all personal personal belongings, and are not within the scope of school teaching, and these things can only complete the teacher's private tasks and are privately granted by the teacher.

Now the teacher's rare generosity is just at the time of the development of a new map, which can be described as gold everywhere. Although Long Zehao was also suspicious, after all, the reward of the school teacher this time was too heavy.

However, Long Zehao couldn't understand it, so he could only temporarily summarize the lack of his own realm, as well as the lack of identity and status, and he couldn't see what was hidden inside.

If you don't understand, you don't bother to think about it, as long as you know, this underground world contains things that even school teachers need, and when he handed in the information, Long Zehao also personally backed up the same information.

Long Zehao is trying to dig out the biggest benefits, and other players are not to be outdone, especially several large player organizations, under the leadership of professional array mages, their progress and Long Zehao, who has just had a special intuition, and even with the cooperation of a large number of organization members, their harvest has already surpassed the duo of Long Zehao and Menglan.

As a large number of people entered the underground world, the scope of the battle between players and aborigines became larger and larger, and without the knowledge of the players who entered the underground world, the spirit of the troops who died in battle was absorbed by the formation that enveloped the entire underground world.

The essence and spirit are absorbed and transformed into law energy, and are sent to the core formation base of the formation, and these specially treated law abilities are slowly integrated into this underground world at the base of the formation under the effect of the formation, which is also equivalent to indirectly integrating into this square Tyrann world.
