The attack of the dark elves continues, and a large number of dark elves die in the attack every day, of course, the losses of the Rakshasa demon as the defender are also quite huge, and the entire Three Peaks Fortress has become a huge tomb, burying tens of thousands or even hundreds of thousands of lives every day. Of course, not every passage is a smooth sailing, among which there have been traps deliberately set aside by the Rakshasa Demon, when nearly 10,000 dark elves attacked the passage, but the Rakshasa Demon put down the boulder to close the exit of the passage, and then little by little cannibalized the dark elves who were trapped inside without reinforcements.

Speaking of which, the passage that Lanina was the first to capture made the fastest and smoothest progress, but even so, it was only a few tens of meters a day, and the passage in the mountain wall was no better than the streets of the city, although the latter also had buildings that restricted movement and blocked the view, but the attacker could still forcibly open a passage in the obstacle in front of him by destructive means, or use magic to directly flatten the block in front of him from mid-air, etc.

On the contrary, in this kind of underground excavation and excavation of the passage, the dark elves can only advance and retreat step by step along these passages dug by the Rakshasa demon, and their advantage in strength cannot be brought into play at all, and they can only repeatedly attack the fortifications arranged by the Rakshasa demon again and again. It's not that the dark elves don't want to find another way in the passage, but they are always powerless, and what prevents them from doing so is not the various reinforcement magic left by the Rakshasa demon ** on the stone walls of these passages, but the dark elves are not good at digging underground, and digging indiscriminately is not only time-consuming and laborious, but also triggers the trap set by the Rakshasa demon in advance, and loses troops in vain.

There is no expert in this area among the dark elves, it does not mean that there is no one in the dark elf army, Reynolds of the Lanina Legion, as a dwarven king, is naturally very familiar with mining ores, building equipment, and digging caves, because the entire dwarven country Black Rock City is a tool forged by the dwarven ancestors of the past generations, plus his hands slowly built over countless years. The Dark Elves were unfamiliar with the passages inside the Three Spires, but Reynolds had lived in a similar environment for many years, and even if he closed his eyes and listened, he could accurately guess what was hidden behind the thick stone walls, which was unique to the dwarves, and it was by this method that they were able to keep digging for precious mineral resources.

No matter how heroic and good Lanina's legion is, it is impossible to fight on the battlefield for ten days and ten nights in a row, they also need to rotate with friendly troops, and when it was their turn to rest, Reynolds began to think about how to dig a passage to bypass the defenses laid by the Rakshasa Demon, and open up a second battlefield from the flank or back, as long as the whole process can be cleverly disguised, so that the Rakshasa Demon will not be discovered in advance, and then find the vital parts of the Rakshasa Demon, Reynolds is confident that he will teach those hairy guys a hard lesson.

Before digging the fortress, the Rakshasa Demon will definitely conduct a comprehensive survey of the geology, rocks, and other conditions here, and then design the most effective system on the basis of this information, including tunnels for passage, barracks for rest, warehouses for storing materials, and fortifications to resist invasions. In terms of walking tunnels, if you pursue time-saving and labor-saving, the straighter the better, but such a passage is convenient to walk on, and it is more convenient for the enemy to break through when attacking, and the enemy's ** division can use magic to release it towards the end of the passage, and the Rakshasa Demon can only use the same means to resist the strong attack of the dark elves if he wants to defend, which is equivalent to the two sides competing for manpower, which is naturally not in line with the original intention of the Rakshasa Demon to build a fortress.

Therefore, all the passages inside the entire fortress must be crooked, and at the same time, in order to prevent the dark elves from opening up the stone walls between the two passages, the Rakshasa demon not only reinforces all the rocks here with magic, but also tries to increase the difficulty of this practice in design, the most obvious is that all the passages here are at least dozens of meters long between the rock walls, and the middle is not completely solid, there are many places where many traps are artificially set, if the dark elves do not pay attention to touching them when digging, they will definitely suffer a big loss。

All of this was revealed by Reynolds, who spent three days trying to figure out his surroundings and then came up with a sketch of the route, in which Reynolds clearly marked all the passages around him, and also indicated the many hidden traps, and finally Reynolds sketched a winding route downwards in these complex environments.

The length of the breakthrough designed by Reynolds is about thirty or forty meters, it avoids all the obstacles along the way, and passes between the two Rakshasa demon's passages many times, and finally arrives at the top of a passage where the Rakshasa demon mobilizes troops, according to the distance and direction, that passage should be the passage for the first city wall outside the Rakshasa demon, but it has been permanently closed, and the Rakshasa demon should not put the center of gravity of defense here, which is also in line with the characteristics of the dark elf surprise attack, who would have thought that the dark elves who are storming the second city wall entrance and exit passage will suddenly appear in the entrance and exit passage where the first city wall below has been closed？

Reynolds's design sketch only stayed in the hands of Lanina for more than half an hour before it was transferred to General Dahni, who nodded and agreed to the plan reported by Lanina after carefully weighing the pros and cons, and immediately dispatched four high-level legendary ** divisions to support Reynolds, although the latter is good at digging caves, but it is not easy to work on the stone wall blessed with a large amount of solid magic, even if it can be successful, it will delay for a long time, and it is easy to attract the attention of the Rakshasa demon, so the purpose of the surprise attack will be lost.

Since the Rakshasa Demon ** masters use earth magic to bless the surrounding stone walls to strengthen their solid effect Banishment and excavation, then these dark elf ** masters can also use the opposite method to apply to these stone walls, destroying their existing magic effects, and even making these hard rocks loose to a certain extent, so as to facilitate the excavation speed of the excavation team led by Reynolds himself.

All of this quietly began under the more fierce onslaught of the Dark Elves on the frontal battlefield, and the Dark Elves did not relax their attack because of the other routes that might appear, they had to drag the Rakshasa Demon to death, so that their commander could not think of going anywhere else, and perhaps because of the Dark Elves' intensified offensive to concentrate the forces guarding other areas, in either case, the benefits outweighed the disadvantages.

Because of the limited time and the great limitations of tools, it is impossible for Reynolds to make a passage for dozens of people to enter and exit like in Black Rock City, he knocked all the way down the rock wall, and then had an assistant to carry out the stone chips, during which from time to time the dark elf ** master came over to use spells to dismantle the solid magic made by the Rakshasa demon ** master, and by the way, softened the hard rock as much as possible to facilitate Reynolds' process.

Reynolds doesn't do everything by himself, he is responsible for digging out the general direction, as for widening the passage and other affairs, there are naturally dark elf warriors in charge, even if it is like this, he can only make a distance of seven or eight meters in a whole day, far less than the nearly 100 meters distance that the dark elves can attack and advance in a day on the normal battlefield, this efficiency quickly became suspicious in the hearts of the dark elves who knew about it, and many people thought that Reynolds was doing this superfluous, because maybe after he chiseled everything, the dark elves would have occupied the Rakshasa demon's barracks, and there was no longer a need for this extra thing。

Even when the vast majority of the dark elves were skeptical or even negative, La Nina maintained a high degree of trust in Reynolds, and it is not an exaggeration to describe it as responsive, and seeing La Nina's attitude, General Dahni naturally overrode the public opinion and gave La Nina their greatest support. With the two of them as backups, Reynolds finally opened a small tunnel connecting the two troop transport passages above and below the Rakshasa Demon on the fifth day of the tunnel, that is, the tenth day of the attack from the outer positions.

Although this temporary tunnel is very narrow, that is, it can allow a dark elf to climb up and down normally, but it is of great significance, Lan Nina personally led the team, including more than 100 of her strongest teammates, along this tunnel that the Rakshasa demon did not know about sneaking into the passage below, and then they followed the Rakshasa demon's own excavation of the troop transport channel and soon broke into a barracks of the Rakshasa demon.

Since the commander of the Rakshasa Demon was very confident in his fortress defense system, he drew most of the troops from several other directions that he considered safe after confirming that the transport passages of the lower city walls had been closed and that the attacks of the dark elves had become more violent, so when Lanina and the others broke into the barracks, there were only fifty warriors inside, and the strongest one was the captain of the hundred-man team of ordinary senior rank.

This kind of character Blade Queen is too lazy to start, and Guan Nuoda understands it with one arrow, and the next battle is not even a one-sided slaughter, and the whole process only lasts a minute. After quickly clearing the battlefield to prevent the smell of blood from spreading and arousing suspicion, Lanina ordered to change her costume and dress herself up as a Rakshasa warrior. Before setting off, Lanina and General Dahni had already discussed how to fight behind enemy lines, so this time they deliberately wore a camouflage mask used by the Dark Elf scouts.

This thing is actually a rudimentary version of the magic mask that Ryan used to make for Reynolds and them, if you really explore carefully, you can't basically hide most of the means of inspection, but now it's a state of war, and the Rakshasa Demon deploys troops quite frequently, how can it be possible to set up monitoring stations endlessly Lang to waste their own time, and Lanina and they don't plan to sneak in secretly to steal any information, just use this thing to get as close as possible to the vital parts of the Rakshasa Demon's area, and the rest of the tasks still have to be completed with scimitars and arrows。
