"Sir, what should we do now?" Navier was really desperate now. When the tentacles attacked her just now, she had already discovered that those tentacles were completely nemesis of negative energy bodies. They were not only immune to negative energy attacks to a large extent, but also feed on negative energy. She has lived in the underground world for decades and has never seen such a strange monster.

There are only two banshees left under her command. In terms of combat effectiveness, Navier knows that it is only possible to rely on Gu Cheng. Her experience along the way has also made her trust in Gu Cheng. Now she can only bet on Gu Cheng.

At this time, two tentacles attacked from the shadows. After the last attack, with Gu Cheng beside him, Sari felt relieved. At this time, she calmly released two healing techniques. The shining golden light cut through the darkness and hit the wall heavily, making a deafening and dull sound. For a moment, the gravel fell, and the dark itself seemed to be afraid of the light, and a sharp and shrill scream erupted from it, echoing in the narrow passage.

Gu Cheng naturally didn't want to give up this opportunity to hide random tasks, so he said, "Naweier, take the banshee through the passage on the left, stop in front of an iron gate and wait for us. Never go in! Sali and I go to the right to see what these tentacles are!"

Before Gu Cheng finished speaking, tentacles attacked on the right, but Sari became confident after several attacks on the tentacles, and immediately threw them on two more healing techniques.

"boom!!"

The dazzling white light and golden light emitted from the healing tentacles were easily captured by the tentacles lurking in the darkness again. However, after several attacks, the tentacles were a little depressed, and they curled up in a ball and immediately retreated towards the right passage.

"We chase it, it can't escape too far."

Sali was still a little scared: "Ro...Mr. Reus, do we really want to chase after him?"

"Don't worry, I'm there!" After Gu Cheng said that, he led Sali and walked into the passage.

Navier looked at the backs of Gu Cheng and the others leaving, and was extremely confused. Gu Cheng's performance along the way seemed to be very familiar with the Nomogen Institute, but now he doesn't know what the monster in the shadow is. It's really suspicious.

“Follow up.”

Navier issued an order to the two banshees. The two banshees immediately used their nothingness skills and then lurked in the shadows to follow. The banshees were both tracking masters, even if they were not inferior to the concealment of high-level assassins, so Gu Cheng and the other two did not find anyone following them, not to mention that he had never thought that Navier would be suspicious to follow behind.

Under the joint pursuit of Gu Cheng and Sali, the tentacle monster escaped all the way back to the nest. At first, the tentacle monster hoped to rely on complex terrain to get rid of Gu Cheng and the others, but its plan was soon determined to be futile. Although Gu Cheng was not sure which random environment and ** would appear in each random room, he was very clear about the terrain in each environment.

Therefore, even without the tentacle monster leading the way, Gu Cheng was still able to find the tentacle nest.

“It’s there!”

After Gu Cheng and Sali turned around the authentic corner again, they stood in front of a huge underground cave and easily found the nest of the tentacle monster.

"Ahhhh!"

However, Sari was shocked by the scene in the cave. Countless thick and long tentacles were squirming on the walls on all sides of the cave. From a distance, they looked like wriggling pythons.

In the center, a huge black heart was beating constantly, and those dark tentacles were stretched out from its body.

Because of the uncertain randomness of the Normogen Institute, this dungeon is also listed as the most difficult dungeon in the mid-term. The combination of uncertain dungeons is a nightmare for many wild groups. It is very likely that the wild group will be destroyed countless times because of a professional combination. The dark tentacle monster is one of the disgusting **. If the Holy Feather Priest in the team is not strong enough, this ** is a nightmare!

If you only rely on Sari, the Holy Feather Priest, it will be difficult to get over this **.

"Sari, wait for me to attract those tentacles and seize the opportunity to use the wind healing technique!" Gu Cheng held the rune dagger in one hand and held Sali with the other hand towards the heart of the tentacle.

Tentacle monsters are usually hidden quietly in the darkness. They use their tentacles to catch the lonely creatures and then absorb the energy in their bodies. Few people dare to break into nests full of tentacles. Therefore, for Gu Cheng, the two uninvited guests, the tentacle heart seemed to feel the danger approaching, and manipulate the surrounding tentacles and sweep towards Gu Cheng and the others.

"Do it!"

Just glanced at the tentacles around him, Gu Cheng immediately gave a decisive order. He quickly cut off the tentacles that attacked Sari around him, protecting Sari to sing spells. Then a golden light from Sari's body quickly spread towards the surroundings. The healing effect of the wind healing technique is much stronger than that of the healing technique, and it is a completely nightmare for those tentacles with negative energy!

The tentacle monsters kept gathering together, forming a thick barrier in front of the tentacle heart, trying to block Sari's attack. But this was not as easy as the tentacle heart thought. The penetration power of the holy light energy of the wind healing technique was extremely strong, and the tentacles wrapped in it quickly became shriveled. In an instant, the tentacles in the entire cave kept falling to the ground like withered vines.

"Sari! Use it again!"

“Hu……………………………………”

Sari gasped a little tiredly, and then immediately released the wind healing technique again. With Sari's current situation, it was still a bit burden to release the wind healing technique continuously.

But the current situation could not allow her to rest at all, and more tentacles swept around her. Unfortunately, the cooldown time for summoning the knight was not over yet, so Gu Cheng could only stand by Sali alone to prevent the tentacles from interrupting the casting of spells.

Facing a large number of tentacle monsters, Gu Cheng remained calm. He just stared at the tentacles that were like waving a vine whip, and cut them off with a rune dagger again and again!

Soon, Sari's second wind healing technique was completed. The effect of the holy light was used on the negative energy collection body as if it was burned by flames. The golden flames quickly began to burn ragingly, and the tentacle heart began to shake the tentacles because of this severe pain, whipping everything around. Unfortunately, these attacks were blocked by Gu Cheng's long sword.

"Huh...he..."

Sari was so tired that she knelt on the ground, but she didn't dare to relax at all.

Faced with the tentacles that had been continuously running, Gu Cheng could no longer let Sari use the Fengzhi healing technique. He picked up Sari who was half kneeling on the ground, jumped over a smuggled tentacle, and rushed directly to the heart of the tentacle in front.

"Sari! Healing Technique!" Of course, Gu Cheng would not stand there as a target for the tentacles, and quickly turned around and avoided the attack of the tentacles, less than 5 meters away from the heart of the tentacles. He was about to enter the range of healing spells, but there were too many tentacles around him. One of them had already wrapped around Gu Cheng's waist. Sari had to grit her teeth and chant the healing spell weakly. Her face turned pale, and beads of sweat as big as beans on her forehead kept falling.

The healing technique accurately landed on this tentacle, and Gu Cheng quickly took advantage of the tentacles to break free. And the next moment, several tentacles attacked from both sides, instantly wrapping Gu Cheng.

"It's this time! Attack the heart!"

Healing technique!? Faced with Gu Cheng's orders and the dense attacks of tentacle monsters around him, Sari dared not hesitate anymore and immediately released the healing technique to the heart of the tentacle.

Feeling that the body is wrapped in holy light, the tentacle heart feels the arrival of death. It waving its tentacles frantically, striking it around like a long whip. Trying to drive out these terrible energy, this cannot pray for any effect. As the most negative energy in the dark, the tentacle heart is even more damaged by the Holy Light spell than the undead creatures.

After all, what monsters with energy bodies fear the most is energy attacks.

Taking advantage of the healing technique to play a role in the heart of the tentacles, Gu Cheng immediately put Sali on the ground, took out the rune dagger and rushed thousands of times. Without Gu Cheng's protection, Sali was instantly entangled by several tentacles. Unfortunately, she was filled with the power of holy light, and the tentacle monster could not absorb it at all.

"Go to die!!! Sound wave slash!!!"

The long sword in Gu Cheng's hand pierced into the heart of the tentacles, drew an arc, splitting the heart of the tentacles, and the dark blood sprayed on the ground along the cut blood vessels.

At this moment, the squirming tentacles around him stopped.

"call……"

Gu Cheng breathed a sigh of relief and looked back at Sali. The scenery in front of him almost made Gu Cheng faint from bleeding!

Due to the energy of the holy light, tentacles could not absorb the energy in Sari's body, so they had to launch a "physical" attack on her. Sari was completely entangled by the tentacles. The black robe was completely torn apart, turning into strips of cloth to stick to her body, revealing the seductive maid outfit inside, and her wrists were tightly tied together and raised up, and her slender legs were also restricted.

His originally pale face also turned slightly red, and he wanted to call Gu Cheng for help but made no noise. Fortunately, after Gu Cheng solved the heart of the tentacles, the tentacles stopped acting, otherwise the consequences would be unimaginable.

Originally, Gu Cheng wanted to continue to appreciate the "beautiful scenery" in front of him, but Sali had already cast a look of help from him, so Gu Cheng had to cut off the tentacles and rescue her.

"Ro...Royce first...Mr....I, I, I..." Sari's face turned red, she hugged her body and curled it on the ground, she didn't dare to raise her head, and she was stuttering in her speech. At this moment, she wanted to dig a hole in the ground and bury herself.

Gu Cheng walked up and helped Sali up and asked, "Is it okay?"

"No, it's okay."

Sari really wants to say something is wrong...

But Gu Cheng had turned around and walked towards the heart of the tentacles and put a piece of rare equipment that had fallen into the inventory: "I'm lucky, I actually dropped a piece of rare equipment."

After the two of them took a break, after coming out of the tentacle nest to meet Navier, Gu Cheng and his group entered the final area of ​​the Nomogen Institute and rushed to the front of the **. Everyone almost killed all the monsters from the door to here again. The number of people made Gu Cheng feel a little overwhelmed!

Although the Banshee brought back information about Gu Cheng and Sali's solution to the tentacle monster, Navier was shocked by Gu Cheng's strength again and again along the way, and now she is a little immune.

At this time, everyone was standing at the entrance of the ** room. Navier stared at a rusty robot of 4 meters high in a pile of mechanical instruments on the platform below and asked inconspicuously: "Is this robot the owner of this underground ruin?"

Although he was several levels higher than himself and others, Gu Cheng breathed a sigh of relief. He did not encounter the most disgusting and unstable portal at the Nomogen Institute. Even if he had good luck, he would have to consider whether to give up the final reward and roll the Hearthstone back to the city...

………If Hearthstone is in the bag……………

"Go!" When Gu Cheng and others stepped into the room, the manned flying demon golem moved.

“………Intruder detected……”

“………Defense mode starts……”

“………Energy mode starts……”

“………Thunder and lightning attack……”

After the Flying Demon Golem was attacked by Gu Cheng's sound wave, the surrounding wheat field puppets also slowly stood up and turned towards Gu Cheng and others. Then, the air in the hands of the Flying Demon Golem seemed to shake violently. Suddenly, a huge fluctuation hit everyone, and the loud sound waves echoed in the void. Except for Gu Cheng who was prepared for this, everyone else was stunned by the sound. The loud voice was like a heavy hammer hitting Sari's heart. The strong sense of shock almost made her faint.

However, the sound wave attack came and went quickly. After Sari released a purification technique on her, the feeling of dizziness became much better. At this moment, the surrounding wheat field puppets had rushed over and rushed towards Gu Cheng and others. The slender steel claws rubbed back and forth. Gu Cheng summoned two summoning knights, and the silver guard held the flying golem, and the demon knight was responsible for gathering the surrounding wheat field puppets together. However, the flying golem is not a pure machine like the wheat field puppet. It is a magical machine created by the dwarf through the combination of rune magic and engineering.

The banshee, who was shocked by the sound thunder, had no time to resist, and was caught by the energy suction cup of the Feitian Golem. Then all the negative energy in their bodies was absorbed. Naveer's only two subordinates also became the "energy meal" of the Feitian Golem. This is the effect of the rune technology magic developed by the dwarf. Even if the banshee activates the Void skill, there is only a bunch of moving energy in front of it.

However, it was not only Gu Cheng and Navier present, but also Sali. Sali first put a guardian shield on those other than Navier, and then hid behind to release healing assistance at any time.

Since the normal dwarfs at the Normogen Institute had already died, the rest were either crazy leper dwarfs or gangster corpses that had turned into undead, so this flying golem was not ridden by the controller, which also reduced Gu Cheng a lot of difficulty.

“Sacred sanctions!!!”
