Rewind the clock by half an hour.

When Tamil left the camp as planned and headed for the Tanikou defense line, Yu Bin was putting a piece of white bone essence from the last corpse into the space bag, getting up and looking in the direction of the rebels' camp.

This is the eleventh patrol he killed, compared with the patrol team he killed before, the last few have been greatly reduced in both quality and quantity, not only have the number of people dropped from ten to five, but not even a ghost can be seen, they are all composed of skeletons and zombies, which makes it much easier for Yu Bin to kill.

"Let's fight!" The reduction in patrols undoubtedly meant that the rebels could no longer spare enough strength to maintain such patrols, and could only give such tasks to the lowliest skeletons and zombies. There is only one reason why the rebels have no time to take care of anything else, and that is the all-out attack of the Imperial Army.

"It's time to see what's hidden in there!" While looking for prey before, Yu Bin also tried to get close to the camp, but before he could get close to the position of five hundred meters away from the camp, he was discovered by those garrisons, facing the garrison composed of heavily armed black warriors and death messengers, Yu Bin immediately chose to escape, he is not a fool, so he will not throw his life here in order to satisfy his curiosity.

But now, in the face of the all-out attack of the imperial army, the rebels should not have the strength to continue to maintain such a strong garrison, Yu Bin can take this opportunity to explore that camp, what exactly needs the rebels to use such a strong force as a garrison.

Six hundred meters! No garrison was visible in sight.

Five hundred meters! From here on, there is nothing that can provide shelter, and once discovered, Yu Bin can only choose to escape here.

Four hundred meters! In this short 100 meters, Yu Bin walked with fear, for fear that he would be made dumplings by the rebels who suddenly appeared.

Three hundred meters! The outer walls of the camp could already be seen in the distance, and the improvised exterior walls made of wood and rubble were full of holes through which the inside of the camp could be seen.

Two hundred meters! Yu Bin could already be sure that there were hardly many soldiers left in the camp, because there was not a single guard to be seen near the outer wall. It is estimated that the pressure on the front line was too great, and the rebels had to mobilize all their forces.

One hundred meters! Through the hole, Yu Bin saw some skeletons roaming around the camp, but their scope of action was limited to a certain area, and they did not patrol the rest of the camp.

Reaching out and grabbing the edge of the outer wall, the outer wall, which was less than a man high, could not stop Yu Bin's footsteps at all, and the rebels obviously did not have enough time to continue to strengthen this defensive structure. With a hard pull of his hands, Yu Bin climbed over the outer wall, clinging to the tent to avoid the sight of those guards, and exploring the empty tents of these people along the way.

Almost all tents do not have any facilities, the undead do not need to sleep or eat, as long as there is enough death energy, they can maintain their combat ability, the reason why tents are set up is to distinguish the area where different kinds of undead are located, and on the other hand, it is also to block the rain. Unlike the undead inland, war-prone areas are generally not completely undead dead land, the rain that falls from the sky contains a trace amount of natural energy, although it will not be fatal, but will increase the consumption of death energy, the use of tents is for this reason, the tent smeared with a layer of animal fat can effectively isolate these unpleasant rain.

Occasionally, there is a tent with a badly damaged undead spirit, either because the soul fire is badly damaged, or because the body is severely disabled or even broken, so in this way, their own death energy is slowly repaired until they are once again capable of fighting.

Naturally, none of these undead have become the military exploits and materials in Yu Bin's pocket, relaxed and happy!

The camp is not very large, and there is no need for the undead to prepare resting tents for the cannon fodder troops, and the largest number of cannon fodder in an undead army is often these cannon fodder, so the size of the camp is much smaller than that of other races.

After searching the other areas, the entire camp was left with only the core area tightly guarded by the skeletons, which was only the size of a football field, in addition to the large tent in the center, including six ordinary-sized tents scattered around, it didn't look special, but in such a small area, there were more than two hundred skeletons patrolling back and forth, and there were three black warriors around each tent to guard, which showed the tightness of the defense.

Yu Bin didn't want to give up so simply, whether he succeeded or not, he wanted to give it a try to figure out what was stored in these tents, which was worth guarding with so many soldiers.

He took a few steps back and summoned the skeletal horse he bought in a corner, all the mounts can be stored in the mount badge, which is a prop that is bought together when buying a mount, the mount badge with the space spell can provide space ranging from ten cubic meters to a thousand cubic meters, the larger the space, the more expensive the price, and this badge can only store the mount and the equipment worn by the mount, and cannot store other things, so few players will spend a lot of money to buy high-level badges.

After summoning the skeleton war horse, Yu Bin controlled it to run towards the core area, the sound of galloping horses' hooves immediately attracted the attention of those guards, and the skeletons who were patrolling around invariably rushed to the galloping skeleton war horses, Yu Bin controlled the war horse to make a sharp turn, and ran towards the periphery of the camp with the mighty skeletons.

But those black warriors did not leave together as Yu Bin expected.

Yu Bin didn't have time to regret it, and took advantage of the plan of these black warriors to be attracted by the skeleton war horse, and sneaked into a tent closest to the core area, which was a full five meters away from the nearest black warrior guard, which was the best attack position Yu Bin could find.

Taking a deep breath, Yu Bin closed the helmet, this full-coverage helmet with a mask came from an unlucky skeleton knight, he happened to meet Yu Bin breaking into the door when he was recuperating in the tent, and the skeleton knight whose soul fire was seriously damaged and was powerless to resist became Yu Bin's sword ghost, and the equipment on his body that was still intact naturally became Yu Bin's trophies, including this full-coverage helmet.

In this way, Yu Bin also gathered the cuirass and leggings, barely making up for the equipment that was destroyed by Cothro before.

Taking a few steps back, Yu Bin pointed at the black warrior across the tent and suddenly charged. The tent, which had already been partially fixed by Yu Bin, was instantly pulled up under the huge force, and rushed towards the black warrior with Yu Bin like a huge shield.

The black warrior who was awakened by this situation held a knife in his hand, but because Yu Bin was hiding in the tent, the black warrior could not find Yu Bin's enemy at all, in this case, should he use the weapon in his hand to chop a tent?

Before the black warrior could make a decision, a sharp short sword pierced his eye socket through the tent cloth and pierced into the skull, and the black warrior whose soul fire was attacked was killed almost instantly, and Yu Bin also used his remaining strength to directly hit the tent he was guarding, and the short sword in his hand was pulled and slashed, and Yu Bin easily broke through a gap and got in.

This sudden situation caused the nearby black knights to turn their eyes, and except for the two black knights who were also guarding the tent, the others remained in place. The two black warriors walked opposite each other along the outside of the tent, and suddenly, when a black warrior passed a tent, an arm stretched out from behind him, grabbed his armor and pulled it violently, pulling it into the tent, and waiting for the black warrior to react, the black wing blade in Yu Bin's hand had already pierced into his soul fire.

After treating the third black warrior in the same way, Yu Bin didn't bother to search for the corpse and began to look inside the tent. Unlike the tents in other areas, a large hole has been dug into this tent, and empty wooden boxes are piled up on one side, and some digging tools can be seen still at the mouth of the hole, and it seems that even the coolies used for digging have been sent into battle to stop the attack of the Imperial army.

Yu Bin jumped into the hole, and inside was a large hollow with a depth of more than two meters, and three underground passages extended from this hollow, and they didn't know where they led.

"Since entering the Yin Wind Valley, how did I get involved in digging holes!" Yu Bin laughed at himself while choosing a passage and walked in.

The height of the passage is only more than one meter, Yu Bin can only maintain a bent posture, and walked along the passage for about twenty meters, which is another underground cavity, but there is no communication between this place and the ground.

There were a large number of magic crystals inlaid on the four walls of the hollow, Yu Bin took out the torch from the space bag and lit it, and what caught his eye made him can't help but take a breath of cold air.

These magic crystals densely inlaid on the cave wall are all fire-type magic crystals, and they are arranged very regularly, at first glance, they are artificially created products, and each magic crystal is connected with magic wires, connecting the magic crystals in the entire cavity into a whole. Yu Bin raised the torch and found that a basin-sized magic circle was depicted with magic lines on the top of the hole, and a large fire-type magic crystal was inlaid in the center of the magic array.

Yu Bin is no stranger to this magic array, because many players have used it in his previous life, and this kind of thing called the overload magic circle is magic thunder in the eyes of players. Tube, once activated, the surrounding magic energy will pour into the magic crystal embedded in the core under the action of the magic array, as the magic energy in the magic crystal exceeds the storage limit, it will eventually cause the magic crystal to explode, and the magic energy stored inside will also explode instantly, with a "boom", a big firework is completed.

This thing is often used as a trap by players, and the explosion trap made by combining it with magic crystals has turned many players into terrorists.

Three passages means that there are at least three of the same cavities, plus there are six of the same tents, and if these cavities are all such traps, you can imagine how powerful they will be.

"Crazy! This amount, it can't be that you want to blow up the entire Yin Wind Valley into the sky, right? Yu Bin looked at those dense fire-based magic crystals, and couldn't help but feel numb on his scalp, and even felt that he couldn't guarantee that these things would explode in the next second, so frightened that he quickly extinguished the torch in his hand.

Returning to the tent along the original road, Yu Bin fled from the road he came from as fast as he could, and those black warriors were still guarding their posts, and they didn't seem to have come to find out.

Yu Bin, who ran dozens of meters, had the first thought of leaving this camp far away, and even directly climbed over the mountain to leave the Yin Wind Valley, who knows what these rebels wanted to do with these things, did they want to die with the imperial army? Anyway, no matter what the purpose is, Yu Bin doesn't want to accompany these madmen to play with his life.

"Wait, you can't activate the overload circle at the same time with manpower alone, that is to say, there must be an activation circle!" Yu Bin stopped, "If you can get that activation circle, hehe, when the time comes, when those rebels are defeated and return to the camp, I'll do it again, oh my God, how much experience and military merit will be gained!" ”

Yu Bin's eyes seemed to appear in front of him an ocean composed of experience points and military merits, an ocean that was enough to drown him!

"No, no, no! Such an important thing is either carried by the rebel leader or kept in a large tent in the center, and I can't get my hands on it! ”

"If you don't enter the tiger's den, how can you get a tiger? Even those diggers have been sent to the front, and even if there are guards in the big tent, it won't be a powerful thing! Think about those experience points and military exploits, with this windfall, how many things can be saved! ”

Yu Bin's heart is at war, on the one hand, it is cautious development, and on the other hand, it makes sense on either side, and Yu Bin is reluctant to give up on either side!

"Fight! People die and birds rise to the sky, and they will not die for thousands of years! After thinking about it for a few minutes, Yu Bin finally made up his mind!

Returning to that tent again, now that he knew that these rebels had set up these traps underground, Yu Bin didn't need to risk passing in front of those black warriors. He picked up the digging tools scattered around the cave entrance, smiled bitterly, jumped into the underground cavity, and dug hard in the direction of the big tent.

A few minutes later, Yu Bin dug through another underground cave: "Sure enough, there are traps also arranged here!" ”

Looking at the dense fire magic crystals on the wall of the cave, Yu Bin was too lazy to sigh anymore, and found the right direction to continue along the channel that had been dug, and dug out one by himself if there was no passage, because the underground had been dug by the rebels like an ant network, Yu Bin did not spend much effort to reach the location of the big tent.

However, before Bin could jump out of the hole, a figure jumped from the top of his head. The two who suddenly met in the dark glanced at each other face to face, and Yu Bin did not hesitate to slash at each other's necks with a sword.

Jumping down was a necromancer, wearing glasses made of crystal, holding a magic book in his hand, looking more of a scholar than a mage.

Of course, even if it is a scholar, it is a necromancer, and unlike scholars of other races, the necromancer's combat power is even stronger than that of a necromancer in many cases.

But the undead scholar in front of Yu Bin is obviously not among them, in the face of Bin's sudden attack, the other party obviously does not have enough means to deal with it, the underground cave is not big, and in the face of Bin's melee profession wearing armor, the mage's crispy skin is simply looking for death. It only took half a minute for Yu Bin to plunge a sword into the opponent's chest, completely extinguishing the soul fire hidden there.

Put away the other party's magic book, Yu Bin jumped out of the hole, the big tent is obviously the design room used by the rebels to plan this huge trap, a makeshift table has a drawing spread out, the drawing is the location of each underground cavern and the range of influence after the explosion, judging from the drawing, once the trap is activated, the entire camp around the range of five hundred meters is shrouded, because the camp is backed by the foot of the mountain, the explosion will also cause a landslide, so that those who are lucky enough to avoid the explosion are buried alive by countless falling rocks.

As for the bait used to lure the Imperial army into the camp, it was naturally the cannon fodder that was summoned.

Activating the magic circle is the magic book, Yu Bin carefully checked the drawings, and found that nearly seventy percent of the underground caverns had been arranged.

"It's a pity that so many magic crystals are all wasted!" There weren't many magic crystals in the big tent, Yu Bin only found a dozen of them, and the others might be placed in another tent or stored in some underground cavern, which was too troublesome to find.

Yu Bin is not a greedy person, and he is very satisfied with the current harvest.

At this moment, a sense of coercion enveloped his body, Yu Bin couldn't be more familiar with it, this is the soul coercion of hero-level characters, in the face of this coercion, any existence that has not entered the hero realm will be affected to a certain extent, and the attributes of all aspects will decline, and the lower the strength, the worse the decline.

In Yu Bin's perception, the source of this soul coercion was rapidly approaching the big tent, and it was likely that the rebels were left behind here, and I don't know why, the other party didn't stay in the big tent like the undead scholar.

But this can't change Yu Bin's current situation, because his own strength is too low, in the face of this kind of heroic-level coercion, Yu Bin's attributes have almost dropped to the extreme, not to mention fighting, even moving is slow to death.

"Alas, it's still not blessed!" Yu Bin let out a long sigh and took off some important equipment and stuffed it into the space bag, the equipment worn by the player when he died will be lost together (legendary and higher-level equipment can be bound through soul binding and will not be affected by the drop), Yu Bin doesn't want to return to the pre-liberation period after resurrection, the space bag is enough to ensure that these equipment will not be lost.

Feeling that the hero-level existence was getting closer and closer, Yu Bin took out the magic book: "Fortunately, being killed by the explosion is a matter of moments, not too painful!" ”

After saying that, he activated the magic book in his hand without hesitation!
