Underground base, mecha training hall.

Xiao Yu sat on the floor in the center of the hall with a serious expression, and his divine sense had already covered the entire underground base.

The more than 300 monks of the 'Yin-Yang Sect' have already entered the first layer of the underground base and are searching house by house, trying to find out Xiao Yu's traces.

The power of the entire underground base is still paralyzed, but it doesn't seem to have any effect on these monks, most of them have lighting talismans such as 'ghost light charms' on their bodies, and some of the monks' magic weapons even have their own lighting effects, these people are like more than 300 moving electric lights scurrying around on the first floor.

In a corridor on the right side of the first floor.

More than fifty monks of the 'Yin-Yang Sect' were slowly marching through the corridor with nervous expressions under the leadership of six foundation building stage masters.

The enormity of this underground base was obviously beyond the expectations of the people of the 'Yin Yang Sect', who thought that the enemy had just fled to the cave and hid, but they did not expect that there was such an extremely secret underground base hidden in this cave.

A monk who has cultivated the tracking secret art walked at the front of the team, the 'Yin Yang Sect' is a 10,000-year-old sect, and the wizards and people in the door are naturally full of talents, and this monk's cultivation of the tracking secret art 'Sniffing Soul Technique' can track the enemy's location according to the little breath left by the enemy when he passes by.

Reaching the end of the hallway, the monk shrugged his nose suddenly, tapped his hand twice on the wall in front of him, and reached out to pull on a hidden handle in the corner.

But when a 'click' sound came from the wall, as if something had been touched, the man reached out and pushed the wall, and the wall slowly slid to the side, revealing a swarthy downward passage!

A long-faced monk standing behind him had a happy look on his face, and turned his head to a Qi Condensation Stage disciple behind him and said, "Hurry up and use the teleportation jade talisman to inform Elder Kong, we have found the downward passage!" ”

This long-faced monk has the cultivation of the late stage of foundation building, and is obviously the leader of this team.

The disciple nodded, took out a piece of jade talisman, and sent a message. After a while, a hazy white light appeared on the jade talisman, and there was obviously a reply coming.

The disciple immediately handed the jade talisman to the long-faced monk, who swept it with his divine sense, nodded, and waved his hand at everyone, "You all go down with me!" Those rats don't have any real skills, Elder Likong said, kill an enemy in the foundation building period, reward ten high-grade spirit stones, kill an enemy in the condensation period, reward three high-grade spirit stones, don't miss this great opportunity to make a fortune! ”

When the monks heard that such a good thing had happened, their faces suddenly turned greedy and followed the long-faced monk towards the passage.

As soon as all of them had entered the passage, the wall suddenly and silently slid up, sealing the entire passage again.

Just before the wall closed, a dozen strange 'dangdang' sounds sounded in the passage, as if more than a dozen metal balls had been thrown in from the outside, jumping down the steps of the passage and rolling down, as if striking an out of tune music.

In a few ups and downs, these metal balls had jumped into the middle of those 'Yin Yang Sect' monks, these monks immediately sensed that something was wrong, one of the monks was quick to reach out and scoop a metal ball in his hand, and when he saw the appearance of the metal ball clearly, his face suddenly changed greatly, and he hissed and shouted, "Not good!" There are grenades! ”

However, it was too late.

"Boom! Rumble! Rumble! ……”

More than a dozen grenades exploded in the passage, and countless shrapnel flew around in the small space, slicing through the bodies of the unsuspecting monks.

After a few seconds, the smoke cleared, and the scene was a mess, and the steps in the passage were covered with the bloody corpses of the monks, no less than twenty or thirty of them, and more than a dozen monks were injured in the explosion, and sat on the ground moaning.

The long-faced monk turned back from the front with a gloomy face, and because he was at the front of the line, he was not affected by the explosion of the grenade, but the three monks he sent in the center of the team and the back of the hall did not escape this fate, and were killed in the passage.

Pity these people have great magical powers, but they have not been used, and they have been killed by this grenade worth only a few hundred yuan.

"Despicable rats! When I catch them, I must peel them off and cramp them, and refine their souls to take revenge! The long-faced monk clenched his fists, his eyes almost bursting with fire.

The storage bags on the bodies of those dead monks were collected by someone, and they were ready to wait until they returned to the ground before they were handed over to the empty elders to dispose of, and as for the bodies of these monks, they were also packed in a storage bag, and when the matter was here, they were transported back to the sect for burial.

After a short period of treatment, the injured monks all regained their mobility, and the 'Yin Yang Sect' sent so many people to Shanghai this time to carry out a secret mission, and almost every monk was given a powerful healing elixir, as long as they did not die on the spot, there was no danger to their lives.

Due to the closure of the back road, these people had no choice but to pack up their grief and indignation and continue to move forward.

The number of the squad of more than fifty people has plummeted by half, and they have not even seen the shadow of the enemy, which makes them feel worried, especially those monks who have been injured, and they have become frightened birds, and they have to look back almost every few steps to see if something will be thrown down, and a few cowardly, even at the cost of divine consciousness and mana, have cast out the protective magic shield and defensive talisman, as if this can give them a little more security.

This passage is very long, almost about five hundred meters, and at the end of the passage is a large iron gate, at the signal of the long-faced monk, a disciple of the 'Yin Yang Sect' who was shrouded in the green aura emitted by the defense talisman boldly pushed the big iron gate.

To everyone's surprise, the big iron door actually opened, and a long corridor was exposed in front of everyone.

Fifty or sixty meters away, a few points of ghost light were moving forward rapidly, as if several figures were rushing in front, as if they had discovered that the people of the 'Yin Yang Sect' had arrived, but they heard someone shouting in panic over there, "Not good!" Come on! They weren't killed, they're already in pursuit! ”

The long-faced monk sneered, and a green folding fan-shaped magic weapon in his hand suddenly shone brightly, illuminating the surrounding range of more than twenty or thirty meters, and he shouted, "Chase!" ”

With the force under his feet, he shot forward like an arrow from a string.

When everyone saw that they had discovered the enemy's traces, they did not dare to slack off, and chased after the long-faced monk.

The long-faced monk has profound skills, and his feet are fast, and he has chased more than ten meters behind those people in a short time, and the green folding fan in his hand has been raised, and the green light on the folding fan is getting more and more vigorous, and he sees that a big move is about to be released.

Suddenly, the figures in front of them turned to the right and disappeared from the view of the long-faced monk, who turned out to be a fork in the road.

The long-faced monk had no choice but to put down the green folding fan and continue to sweep forward, and when he came to the fork in the road and was about to turn right, his heart jumped violently, and a strong sense of crisis arose from the bottom of his heart.

Turning his head sharply, he saw a huge red lightsaber carrying unparalleled power, slashing down from the left side of the fork in the road.

All this came so fast that the long-faced monk didn't have time to dodge, and only had time to activate a yin-yang magic shield and block it in front of him, but when he heard a 'snort', the red lightsaber split the yin-yang magic shield without hindrance, splitting the long-faced monk in half.

At the same time, the 'Yin-Yang Sect' monk who was closely following behind the long-faced monk was also raided.

A huge sword shadow full of terrifying flame energy slashed forward from behind him, slashing fiercely into the group of monks, and the flame energy contained in the huge sword shadow suddenly exploded, the flames rolled up, and the fire snake danced wildly.

Under this blow, three or four more monks of the 'Yin Yang Sect' were killed.

But that's far from the end.

A huge sword shadow filled with huge water energy and a huge sword shadow full of thunder and lightning slashed down one after another, shattering the magic shields that had consumed most of their defensive power in the first attack of the flame sword shadow, and these two attacks took the lives of more than ten monks.

Just when the seven or eight surviving monks secretly rejoiced and thought they had escaped, five tall silver-white figures suddenly appeared in front of them, exuding an extremely thick bloody murderous aura on these five tall figures, especially the murderous aura on the particularly tall silver-white figure in the middle was the strongest, and the terrible screams instantly resounded throughout the entire corridor.

From the beginning to the end of this series of attacks, it was only a short dozen seconds.

More than twenty monks of the 'Yin-Yang Sect', including one late-stage foundation building monk and two early-stage foundation building monks, all fell into this long corridor.

Xiao Yu dispatched a fire-based attack team here, as well as Meng Wei, Hei Yu and Ah Feng's three squad leaders, who had previously thrown grenades in the back, and those who lured the enemy in front were several members of the earth-based attack team, although the spiritual power in their bodies was almost exhausted, but these monks were all thieves, and they were naturally familiar with this kind of work, and they were no longer familiar with it.

Quickly scooping up the storage bags on the dead monks, Meng Wei whistled, and the men disappeared into the dark corridors again.

At the exits of the other two passages leading from the first floor of the underground base to the second floor, the Fire Cloud Dao people with a fire attack team, and Hao Yilong with a water attack team were also doing the same thing, and around them, the corpses of the 'Yin Yang Sect' monks who were not blind were also lying around.

These people are afraid that they will die, and they can't understand why, in the same dark environment, the enemy seems to be unaffected, sneak attacks, ambushes, traps, assassinations, all kinds of means are used, and the timing of each attack is just right.

In fact, the secret of all this is on Xiao Yu in the mecha training hall, at this moment, his brain is like a central processing machine, analyzing the information in every corner of the underground base from time to time, and issuing orders to the three teams of Huoyun Daoren, Meng Wei and Hao Yilong.

The powerful Divine Sense that covers this underground base allows him to keep abreast of enemy movements, inform the three squads of where to set up ambushes, and the strength and strength of the opposing squad. Of course, the team led by the two Jindan period monks would never let the Huoyun Dao people ambush them, not to mention that the powerful attack and defense capabilities of the Jindan period monks were not matched by them at all, just the divine sense that they could cover a hundred meters was enough to penetrate all the ambushes aimed at them.

To Xiao Yu's surprise, they seemed to know that the three squads were ambushed by the enemy and annihilated, and they were gathering everyone together, and he and Tianyi each led half of their men to kill the second layer violently.
