"This won't work!" Under the attack of the constantly attacking shadow beasts, although the group has not suffered casualties, the fatigue caused by the long battle is unavoidable. The twin axes in Liu Li's hands have been transformed back into giant shields, and the mechanism that could have been transformed into two hand axes has long been damaged due to overwhelm in the previous battle.

"Hill, is there any space nearby to defend and we can't stay in the tunnel any longer. "The dark cavern is huge, let alone a day, even if it takes dozens of times longer, no one has the confidence to explore it completely, and this is still not taking into account the state estimates of the shadow beast's attack. The underground tunnels are swaying, and the mercenaries who explore will naturally choose those fortified underground grottoes to set up resting spots.

"There's one not far ahead, but it's too hard to get past it. Ciel used the heavy shield in his hand to smash a smaller shadow beast away, and took a moment to say.

"Eve, Bluman, Toru, you three get ready behind you. Hill shows the way, squirrel, you protect Hill. Lynn, seize the opportunity in a moment and rush over with me. Liu Li assigned the task through the psychic communication network, and the giant shield was placed in front of him at the same time, and he began to cast spells. If you continue to spend it in the tunnel, even if you don't wipe out the whole army, you can only return to the ground, so that this exploration will end without a problem.

A small azure arc of electricity wrapped around Liu Li's body, which was the blessing of "flash", and at the same time, the power of purple thunder and lightning condensed beside Liu Li. After detonating the ancient runes, it became more and more difficult for Liu Li to use the more powerful azure thunderbolt, and the consumption of mana also increased a lot. In this situation, he didn't know how long he would have to fight, so he could only try to save his mana when casting spells.

The purple-red power of thunder and lightning finally condensed into three electric balls that emitted dazzling light, and Liu Li did not wait, and directly activated the power of the spell. Three purple-red balls of lightning shot out one after the other.

Under the control of Liu Li's exquisite spells, two purple-red electric balls that shot forward smashed left and right on both sides of the stone wall of the tunnel, but they did not dissipate, but began to move along the stone wall. As the speed of the electric ball gradually increased, it even formed a purple-red thunder ring in front of everyone's eyes, which was set on the inside of the tunnel.

The lightning ring slowly pushed forward, and just as the ring was about to envelop the Shadowbeast closest to the team, the purple-red electricity connected the two electric balls together, and in the process of spinning, a wall of lightning and lightning formed in the tunnel in front of it, and pushed it towards the Shadowbeast. Just like the trials that Wells gave him when he was still in the first order, after coming to the city of Eleonor, the flat wall of electricity seemed to burn all the creatures in its place. In fact, Liu Li's electric wall is added, in order to prevent the spell from decaying as it advances, Liu Li has not only maintained the supply of elements in the electric ball, but also added "mang" to it. The flickering blue arcs of electricity on the purple-red wall easily sliced through the shadowbeasts' fine scales, incinerating their flesh and shattering their bones.

The electric ball that shot backwards was a little simple and crude, it was a "thunderclap". Toru and Eve, who had already received Liu Li's instructions in the psychic communication network, waited attentively to guard against possible fish that might slip through the net. As for Bruman's Heroic Spirit, his existence only depends on whether there is still enough death element in the "Bone of Secret Words" for him to use, and at the moment when Liu Li has just replenished the element, he is the one who fights the hardest. It's a big deal to be reborn from the "Secret Bone of Words" when you die, anyway, the soul core is imprisoned in that bone and can't be separated.

For the surprise attack of a small number of shadow beasts in the rear, Liu Li's approach was to block, not eliminate. Although most of the shadow beasts were only injured and did not die, they were indeed paralyzed and no longer able to pose a threat to everyone.

"Ciel, hurry up, the spell won't last long. "Liu Li is a family member who knows his own affairs, and these three electric balls do not consume too many elements, probably only accounting for 20% of Liu Li's total elements. However, the consumption of spiritual power by accurately controlling them is not small, although the thunder behind is nothing, but if you want to maintain the two electric balls in front of you to continue to clear the field like now, it is estimated that it will only take half a minute at most, and Liu Li's spiritual power will be overdrawn.

"It's almost there, and the fork in the road ahead is on the left, and there's the end there. The group followed behind the electric wall, looking at the burned corpses of the shadow beasts, and hurried forward with the stench of burning fat. The shadow beast in the rear gradually got rid of the paralysis of its body and pursued everyone again. In desperation, Lin had no choice but to go to the rear of the battle formation and work with the three of them to guard against those vigorous pursuers.

There are not many shadow beasts on the fork in the road on the left, war beasts are already scarce, and shadow beasts do not often open new tunnels, this common resting spot for mercenaries is quite safe. This is a common underground cave, and the hemispherical space is not too large, but it is more than enough to accommodate dozens of people to rest. There is only one exit from the cave, and even if the Shadow Beast continues to raid, as long as there is a person with high enough combat power to guard the entrance of the cave, it is enough to be able to do it in one place, so that others can temporarily relieve the fatigue of the long battle.

Now in the team, there are only two people with enough combat power to defend, except for Lin, who is about to break through to a mid-level martial artist, and the only one left is Liu Li, who is the captain. Compared with the Lori who has been fighting, Liu Li, who still has the ability to cast spells, took over the task of defense without giving up, and this terrain is indeed very suitable for Liu Li to play.

The tunnel at the entrance of the cave is more than two meters wide, which can accommodate two shadow beasts to pass through in parallel, if Liu Li is still holding a shield to defend, it is indeed difficult for one person to hold such a large area, but Liu Li's real weapon is not the crystalline giant shield that he smashed aside. As soon as his mind moved, the giant sickle "returned" in Liu Li's hands.

With "Return" in his hand, Liu Li's heart was unusually calm, and he had a feeling of being connected to the weapon in his hand, which he had never had before when using the giant shield. The azure arc of lightning kept shining on his body, sometimes flowing to the weapon in his hand, and with the swing of "Return", the black elements also gathered, forming a series of pitch-black shadow blades on the trajectory of the giant scythe.

The shadow beast that rushed to the front was less than five meters away from Liu Li, and it couldn't help but be ecstatic to see that the human who had killed many of its companions had actually given up the heavy weapon that it had originally held in its hand, this not intelligent demonic beast could not detect the power of "Return" at all. Faced with the slender weapon in the hands of the enemy, it pounced confidently, unaware that this was the last action of its life.

The "Return" in Liu Li's hand swept out from left to right, hitting directly on the claws of the shadow beast, and the thunder and lightning power contained in the weapon exploded in the moment of the exchange. The glowing arc of electricity not only illuminated the entire cavern, but the paralyzing sensation of lightning also stiffened the sudden attack for a moment, and then the shadow blade formed by the dark element slashed through with a sharpness no less than that of the giant scythe, and the first shadow beast was decapitated with a single blow.

The second larger shadow beast followed behind its companion who rushed out rashly, taking advantage of Liu Li's sickle blade to sweep and rush towards the cave before it had time to turn around. It knew that as long as it gave priority to dealing with those humans with slightly weaker combat effectiveness, Liu Li, who was stopped at the entrance of the cave, would not be able to support it for too long under the siege.

Liu Li, who had already turned on the state of "omniscience", naturally would not be unaware of its movements, and with a twist of his wrist, he forcibly turned the "Return" back with great force, and the scythe blade was directly hooked on the waist of the shadow beast that flew past from his side. Liu Li made a mistake at his feet, and the force of the "shock" exploded, not only slashing the enemy hooked on the "Return" directly, but also the sharp tip of the scythe directly slashed at the top of the head of the third shadow beast, penetrating the brain. Then the shadow blade that followed stopped the attack of the fourth demonic beast......

"Return" danced faster and faster, followed by a faint shadow blade from time to time after the bright crescent, and under the lightning burst generated by the red element, I don't know how many demonic beasts died in Liu Li's hands.

Liu Li didn't stand at the entrance of the cave to defend, but retreated a little distance, which admittedly would allow him to face more demonic beasts, but it also gave him more room to exert himself. The sharpness of "Return", the mystery of the shadow blade, and the power of thunder and lightning all form the dance steps that represent death. Liu Li had already exerted his skills to the extreme, and even the bombardment of the shadow blade and electricity was mixed with martial arts. No matter how the attacking Shadow Beast adjusted its stance, it couldn't dodge the deadly blade.

The blood of the Shadow Beasts stained the ground of the cave entrance red, one, two...... 10, 11...... The increasing corpses of the mutilated demonic beasts gradually piled up at the entrance of the cave, but Liu Li's movements became more and more fluid. No amount of practice can compare to a real battle, and Liu Li's skills in using the giant scythe have steadily improved as the battle progresses.

The Shadow Beasts were terrified, and they could no longer keep up their offensive in the face of an invincible enemy. The demonic beast that was close to Liu Li hesitated, and the companions behind him also let out a whimpering sound of fear. There was no trace of indomitable momentum in their cries, and there was only fear in their voices.

Finally, the first retreating Shadow Beast appeared, staring at the invincible enemy from a great distance, with no madness in its gaze. At the moment when it met Liu Li's gaze, seeing Liu Li's cold gaze, fear grabbed its soul. With a mournful roar, it turned and fled.

Looking at the retreating demonic beasts, Liu Li didn't chase after them, not to mention that the long weapon "Return" was not suitable for use in narrow caves, and he himself was almost at the limit.

The battle was not long, and it only took more than ten minutes from the time everyone arrived at the cave. But in these ten minutes, Liu Li almost squeezed out the last bit of strength in his body, if it weren't for the physique far beyond ordinary people, he might not have been able to hold on for a long time. But at this time, it is still not the time to rest.

Liu Li walked over to the corpse of the Shadow Beast that had been decapitated by a single blow, it was the most powerful individual in the attack and the first to die. With a wave of "Return" in his hand, he dissected its head and presented it on the magic crystal in front of Liu Li's eyes, and the ominous aura that had not yet dissipated shocked Liu Li's heart. This kind of aura is so familiar, just like the manic and riotous feeling that Liu Li has been exposed to and used.

"Red...... element?"
