"Looking back now, when we did not withdraw to the mountain defense line, the enemy's attack was always aimed at attrition and exhaustion of our army, and the main army never attacked with all its might. Judging by the battle report from General Francis's side, the situation is similar. Relying on the advantage of the terrain now, the consumption of kobolds does not work, and it is possible that the enemy is looking for a way to make up for the disadvantage of the terrain these days. The next time the enemy's main forces are involved in the battle, it may be a decisive battle. Evra groaned.

"The enemy is fighting on multiple fronts, and it is impossible to have too many troops. Judging by the situation, it is possible that they will withdraw after the opening of the breach and then withdraw to other forces that have not protruded and come to the ground to establish outposts and merge into the open gap. Achilles walked over to the hanging map of the continent and stared at the circle circled above according to the current situation. Among them, the southeast of the continent, that is, the southeast of the Inca Empire to the sea, the big circle is shocking.

Hearing Achilles' words, Evra also turned his head to the map and stared over: "Quite possibly! Lanardo, immediately report the battle reports and analyses of these days to the military headquarters and General Francis at the same time. ”

Guderian was also shocked, the enemy started the war in order to return to the surface. Why, then, if the gap has been opened, why make senseless sacrifices elsewhere? If so...... The Inca Empire, how long can it last?

Everyone's minds were not much different from Guderian's, and they couldn't help but look at each other, their faces unusually solemn.

"Judging from the report from the military department, it will take at least a month for the reinforcements of Dayu and Totai to reach the front line in the Inca. With such a long interval of time, if the enemy concentrates his forces and is under the containment and cooperation of the Sea Clan, can the Inca Empire, surrounded by the sea on both sides, support the arrival of reinforcements?" Brigadier General Ali took off his helmet and touched the top of his half-bald head, perhaps not only the current battle situation that annoyed him, but also the sadness of the middle-aged man's bow.

"Who knows?" the crowd fell silent.

"The kingdom is closest to the Inca front, and we have no way to draw troops to support the Inca Empire without confirming the withdrawal of the enemy's main forces to join forces on the Inca Empire front. It's just too passive. Lanardo broke the silence and said helplessly.

"Let's tentatively organize a counterattack. Force the kobold back into the passage and see if the enemy's main forces are still there. If we were, we wouldn't have been allowed to re-block the underpass. Evra said.

"Good!" Guderian agreed. Everyone thought about it and agreed.

"It is also possible that because of the backward movement of our line, the enemy tempted us to counterattack and fight us in a relatively flat field in the valley. We need to be prepared for that. Evra continued. The crowd agreed.

So everyone began to plan a trial counterattack and guard against the enemy's possible attempts at a decisive battle. Although there are nearly 50,000 troops on the defense line today, 20,000 are new recruits brought by Guderian, and the combat effectiveness of short-handed combat can be said to be inferior to that of kobolds. 10,000 is the Jiangzhou city defense army brought by Ali, and compared with the defense line soldiers led by Evra, there is also a certain gap in combat effectiveness. The defense line originally had 40,000 troops, but nearly 5,000 soldiers were lost in the defensive battle of the underground passage, and more than 6,000 soldiers were consumed on the ground defense line, plus those who were wounded and temporarily incapacitated, only 25,000 troops were left to fight. It can be said that if there is a decisive battle, only these 20,000 soldiers can fight head-on, and if there is a negligence, it is easy to be eliminated by the enemy. At that time, the El Niño Line will also become a gap in the kingdom, in which case the fall of the Inca Empire is just around the corner, and the kingdom will also be in the current predicament of the Inca Empire. After the discussion, everyone left to prepare for their own tasks.

After a day's preparations, Guderian was summoned by Evra to the chamber, with Natasha with him.

"General Guderian, I plan to form an elite squad as an outpost, go straight down from the opposite cliff, and go to the underground passage from behind the kobold camp to search for the enemy's main force if it is still there. Evra was straightforward about what he thought.

Guderian looked at the two of them, and probably understood what he meant.

"With your martial arts, you should be the first person on the defensive line. Evra continued, "I will select fifty warriors with outstanding martial arts for you to lead the search. Of course, Natasha will personally lead ten high-level mages to set off with you. "Evra's military rank is lieutenant general, and he belongs to the commander of the defense line in his position, Guderian is only a major general, and he is only the general of the dragon guard in his position, and he is under the jurisdiction of Evra in the defense line, so there is no room for doubt. Of course, Guderian does not question either.

Guderian looked at Natasha, who was pretending to be affectionate and looking at Guderian, and Evra on the side couldn't help but roll her eyes at Natasha. Only then did Natasha retract her eyes and said solemnly: "We don't need to say more about the danger of this mission. If you encounter the enemy's main force and high-end forces, the probability of being able to retreat is very low. But we had to go. ”

"When are you leaving?" asked Guderian.

"Tonight when the kobolds attack. Evra said.

"Good. ”

In the middle of the night, in the valley under the silver moon, the kobolds attacked again. Though useless, they charged endlessly for many nights. Counting the number, there were no less than seventy or eighty thousand kobolds who died—the ashes and residues left over from the human mages piled up and burned by the human mages on the valley were everywhere. However, the number of their charges has never decreased, and I don't know how many kobolds exist in the underworld, and how Drow feeds them. Even these rudimentary leather armor and scattered weapons are a lot of them. This kind of fearless and crazy death, even the most intelligent ogres and goblins will not do this, and can only admire the means of Drow slavery.

As the kobolds stormed the slope under the defensive line, Natasha and Guderian led fifty warriors and mages wearing only leather armor and armed with swords, bows and arrows to the passage of the defensive line above the cliff where the entrance to the underground cave was located, and fixed a dozen bundles of rope and threw them down. Natasha and the other mages blessed everyone with the lightness technique, and then led the mages to float down the cliff. Guderian, also dressed in light leather armor and a sword and bow, took the lead and slid down one of the ropes, while the warriors waited on the side - Guderian and the mages had to do their reconnaissance work first, so as not to fall directly into the middle of the enemy, or find the enemy and not be able to land and turn back and hang directly on the rope. The mages, led by Natasha, floated above the entrance of the cave and did not descend directly to the ground. Above the entrance of the cave to the ground, there is a height of nearly twenty meters, and from here, the kobolds' camp is in front of them. Under the faint milky light of the silver moon, the camp was empty. The rope was not hung directly to the ground, but was held up by the mages with spells and coiled above the mouth of the cave. When Guderian landed at level with the mages, Natasha led Guderian and the four mages around to the right side of the cave entrance and landed on the ground more than thirty meters away, while the other mages continued to hold their positions and hold the ropes.

When Guderian landed, he quickly drew his slasher and rushed into the huge hole. The ground at the entrance of the cave has long been paved or flattened in thousands of years of garrisoning and fighting. Various inward fortifications are still faintly visible. Guderian leaned over and probed around the entrance of the cave, and in his vision and sense, there was no area at the edge of the cave that was sixty or seventy meters wide and stretched diagonally downward

Any enemy exists. So he threw a few stones at Natasha, who was guarding near the entrance of the cave, as agreed. Afterwards, Natasha came to Guderian's side, and the two of them marched to the cave on guard from side to side. Two of the four mages drifted to the top of the cave, while the other two continued to guard the entrance of the cave.

Inside the passage, about seven or eight meters near the entrance of the cave, you can still see the ground and the surrounding things by the night light outside. After Guderian and Natasha had penetrated fifty meters, it was already pitch black, and Guderian could only move forward by relying on Natasha's left hand to guide him. Of course, Guderian's sense of hearing and telepathy was still sensitive, and he was confident that he would not miss an enemy if there was an enemy. There are various human fortifications in the cave, and although some of them are destroyed, they cannot be climbed silently. Natasha relied on her keen mental strength to find her way, and led Guderian on the only path among the fortifications more than three meters wide. At Natasha's induction, the straight and diagonal downward path began to meander, and the stone walls on both sides gradually narrowed from the width of sixty or seventy meters outside to the width of about twenty meters, so Natasha stopped and did not continue to advance. Guderian's sudden stoppage of Natasha almost hit her back. Fortunately, there was no light, otherwise the embarrassment on Guderian's face would have nowhere to hide.

Natasha took a magic crystal from her cuff and injected magic into it. At the same time, the mages outside the cave entrance and on the cliff wall also took out a magic crystal that they were carrying, and only a few faint flashes of light flashed in it. So, the warriors on the cliff began to climb down, and the mages above the cave entrance lowered the ropes they were holding on to the ground.

Guderian and Natasha waited in place, not talking, and this place was nearly half a mile away from the entrance of the cave. In the silent passage, except for the occasional breeze blowing through the stone walls, only the powerful and orderly heartbeat of Natasha - in Guderian's senses. Guderian controlled his heartbeat and breathing, clenched the slasher, carefully sensing the movement ahead, and could burst out with the most powerful combat power at any time. After about a quarter of an hour, the warriors waited quietly at the place where Natasha and Guderian were in the small light technique held up by the mages.

"Two miles down from here, our first line of defense. Further down, there are huge underground caverns, where there are many passages leading to the underground world and other places, which are very complicated. That's where we want to be. Natasha magically propped up a ripple in front of her, a soundproof wall, to Guderian and the others, despite what had been said during the previous assembly.

"There are no guards in the passage, and it seems that the enemy's main force has most likely been transferred. Guderian said.

"Let's see. Natasha said.

Guderian nodded, glanced at the warriors, and moved on. Natasha motioned for the mages to extinguish the light and guide the warriors, then quickly caught up with Guderian and reached ahead to take Guderian's left hand. For a moment, darkness returned to the passage. The team walked slowly through the passage.

After a little more than a mile, a faint light and the shadow of a kobold guard appeared around the corner of about fifty meters in front of Natasha and Guderian. Natasha glanced back at Guderian, let go of the hand holding Guderian, and blessed Guderian with a light body technique.

Guderian hunched his body and moved quickly through the passage, Natasha floated alongside him, and after a short time he approached the corner and saw the kobold figure reflected in the stone wall.

Six heartbeats, Guderian sensed. Guderian picked up a stone and threw it at the stone wall behind him more than five meters from the corner. The noise caught the attention of the kobold guards.

"%@/——......?" There was a strange exchange of sounds. Then Guderian sensed two heartbeats coming around the corner.

Two kobolds appeared in Guderian's field of vision with torches, and then stood still, unable to move anymore - Natasha's right hand pointed at them, petrified.

"@&%!" another incomprehensible sound, and then all four heartbeats came around the corner.

Guderian held the knife across his chest, his body bent slightly. When the four figures appeared next to the petrified kobold, Guderian rushed over like a sharp arrow, and at a distance of five meters, only a shadow and a fleeting sword light were seen, and then the four figures staggered and cracked, and blood was sprinkled on the stone wall and the ground around the corner. At this time, the two kobolds who were petrified appeared to be petrified. Only then did Guderian notice that these kobolds were not the same as the cannon fodder kobolds outside. These kobolds are not relatively robust, and their eyes are not red. Natasha walked over and nudged the two petrified kobolds, and they fell to the ground with a thud, leaving only two sets of leather armor and two spears.

Passing around the corner, torches were lit every thirty meters or so in the passage ahead. In the underworld, not every race has night vision. Everyone walked all the way until they found the second group of guards at a corner more than sixty meters away. After simply dealing with the guards, he moved on. After clearing six groups of guards, we finally came to the top of a huge karst cave.

At the entrance to the cavern's surface passage, there are ruined human fortifications everywhere. Natasha petrified the four kobolds standing at the entrance and didn't touch them, leaving them to stand like that. From a distance, it's really hard to tell the difference between dead and alive. Guderian leaned down at the entrance of the passage and looked at the cave diagonally below—the cave was almost a mile in circumference, empty except for a group of twenty kobolds patrolling the entrance to the passage. Around the cave, there are several passages with torches at the entrance, and I don't know where they lead.

Observing the enemy patrol, Guderian immediately turned back and prepared an ambush with the others to kill them silently.
