Gu Cheng and Sali followed the corridor, which was probably the lounge of the Mysterious Refugee. There were 2-3 skeleton magicians in each lounge. Gu Cheng did not intend to kill them, but continued to walk forward with Sali. After walking through more than a dozen rooms in a row, he finally found a room similar to the control room in a room on the right. There were also 3 skeleton magicians in this room.

"Sari, come."

“Ah? Ah??”

As we all know, the Holy Feather Priest serves as an auxiliary position in the Beast God Continent, known as "Husband". They basically play auxiliary roles in the team. Healing injuries to others, releasing shields and buffs is the most common thing for the Holy Feather Priest. So most of the time they are in the back of the team. As for fighting on the front line? Sari probably never thought about this kind of thing! Just like just now, Sari was planning to find a better corner to hide when Gu Cheng was fighting with the skeleton magician, and then release auxiliary magic for Gu Cheng.

Upon hearing this order, a trace of doubt flashed through Sali's mind, but since it was Gu Cheng's order, she still obediently raised her hand to release the punishment of Shengyu.

"No need to use attack magic, just use healing."

"ah?"

Healing? That is a healing spell. Why do you need to cast this monster? However, this question only flashed through Sari's mind. Soon, Sari raised her right hand and cast a healing technique on the monster in front of her.

As a 45-level advanced holy feather priest, Sari's skills are still very good. Although healing techniques are generally used close to the target, they can also be used for casting spells in the middle distance. As long as you can determine the position of the target, it is not difficult to cast it. Sari is even more relaxed and relaxed, but probably because the other party is not a companion, but a monster, the girl's movements are a little hesitant, but she still completed the spell very quickly.

A white stream of light immediately emerged from the air and then wrapped around the skeleton magician in the lead. According to the original effect, the life wrapped in it will immediately recover to a certain degree of injury, and even the effect of healing the wound and revitalizing the spirit is the basis of the spells used by the Holy Feather Priest.

But the performance of the skeleton magician was completely beyond Sali's expectations. While being shrouded in the white light, the skeleton magician's entire body trembled violently. Then the skeleton magician's bone frame softened and slid down to the ground like it was taking off its strength. This surprised Sali, and she subconsciously lowered her head and looked at her hands, unable to figure out how she could release a spell with such lethality.

“Crunch!”

When the two skeleton mages next to him saw their companions being attacked, they bit their upper and lower jaws back and forth, making a chilling sound, and then immediately gathered flame magic in their hands, but at this time Gu Cheng rushed up.

After seeing the performance of the skeleton magician, Gu Cheng was very calm. You should know that the positive energy generated by the healing technique is the nemesis of the dark negative energy collection such as skeleton monsters. Although Sari didn't understand why a healing spell had such an effect, in reality, the players in "Spirit Pet Online" were basically very clear. In their opinion, the healing technique was just wearing a vest that covered people's ears. The essence of this spell was to cast a positive energy. However, positive energy would bring healing effects when encountering a living body. When encountering a dark negative energy, it was the reverse effect, just like the effect of dark magic against positive energy and negative energy.

As for this issue of positive and negative energy, a joke has been circulated among the players of "Spiritual Pet Online": The most tragic thing about a dark-type spiritual pet is to encounter a group of dark-type monsters - because the spells of dark-type spiritual pets are basically from negative energy, and using them to attack dark-type creatures that also use negative energy will only have the effect of healing rather than destruction. Until the official corrected this problem later, the problem of positive and negative energy will only appear on low-level creatures, or on low-level magic. High-level spells will receive a decreasing effect, but they are not completely invalid. The damage becomes double and 1/2 value, just like other attribute restraints.

Otherwise, the plot of the battle between light and light, dark and dark NPCs will not be able to continue. You should know that the six high-level lords in the dark source camp who hold heavy power will have a small fight for three days, one small fight for ten days. If it is invalid, the scene will be a bit funny...

Seeing that the healing technique was so effective against the skeleton mage, Sari was already struggling whether to continue to release magic on the remaining two skeleton mages! But at this time, Gu Cheng had already dealt with the two skeleton mages. After all, two level 40 monsters are nothing to Gu Cheng.

After dealing with the skeleton weakened by Sali, Gu Cheng raised his head and looked at Sali and said, "Let's take a break, the next thing is not that simple."

"Ah?" Sari didn't quite understand what Gu Cheng meant.

Gu Cheng walked into the room. The control room was not big, only about twenty square meters, with alchemy instruments on both sides. In the center, it was a magic control device that controlled several key channels of the Mysterious Refuge. If you want to enter the underground world from the Mysterious Refuge, you must open these magic devices and open the doors of each channel.

"Open these magic devices and activate the magic alarm. All the skeleton monsters we see along the way will gather here, which means that if we don't solve them, we won't think of this room!"

"ah!!"

After hearing this, Sari remembered the number of skeleton warriors and mages she saw along the way, and couldn't help but exclaim.

Gu Cheng comforted: "But don't worry, the space here is limited, we will only face 5 or 6 skeletons at most at one time, so there will not be too big problems."

"Oh...oh!" Sali looked at the surrounding environment. The entrance was only one meter wide. The space here was indeed as Gu Cheng said. At most, 5 or 6 skeletons could only rush in together. Only then did she feel much more at ease.

"It's ready!" After Gu Cheng said that, he pulled down all the wrenches of the four control channels on the console.

At this time, the two of them could clearly feel a strong magic wave around them, followed by a "boom-boom" sound from afar, followed by the sound of moving footsteps and the friction between weapons and the wall.

"Sari, stand behind."

Gu Cheng blocked the doorway from the silver guardian and the demon knight, one left and one right. Then, a large number of skeleton warriors holding various weapons rushed in.

"Sari, use healing techniques to attack the two skeleton mages behind!"

Gu Cheng shook his figure and rushed towards the skeleton warrior in front of him, and gave orders to Sali at the same time. At the same time, the two summoned knights blocked the two skeleton warriors rushing into the room.

"yes!"

Perhaps inspired by the effects of the previous healing technique, Sali's answer was also very energetic. Soon, two abundant healing techniques shone from the sky and fell on the two skeleton mages behind Gu Cheng and the skeleton warriors blocked by the summoning knight. The gentle light enveloped them, stagnating their attempt to release the spell.

Although Sari's healing technique weakens the abilities of the skeleton mages, it only makes them unable to use spells for the time being. If they don't solve them quickly, Gu Cheng and the summoning knight will be attacked by spells while facing the attack of the skeleton warriors.

However, for Gu Cheng, of course, this kind of thing would not be allowed to happen. He was wrong and barely avoided the long axe slashed out by the skeleton warrior. Then the black sword blade in his hand suddenly turned and stabbed forward.

"Phantom Slash!"

The rune dagger accurately hit the slender spine of the skeleton mage, cutting off the skeleton head, which could only be supported by this bone. After the crack was broken, the skeleton rolled to the ground. The extremely cold attribute of the rune dagger also helped Gu Cheng a lot. Many skeleton monsters were affected by the extremely cold attribute after being attacked, and their movements were much slower. At this moment, more skeleton monsters also attacked.

"Silver Guardian! Demon Knight!" Gu Cheng issued an order to block the skeleton mage from releasing magic from the silver guardian, and then blocked the skeleton warriors outside the door with the Demon Knight. With Sari's Holy Light Magic Assistance, the battle lasted for a full half hour, and the skeleton warriors' offensive gradually slowed down. But Gu Cheng felt that the number of skeletons was much less than what the two of them had seen along the way, which made him feel a little uneasy. Even he could not tell the reason for this inexplicable sense of danger.

"call……"

Looking at the skeleton racks that were covered with the ground, Sali wiped the sweat beads on her forehead and felt a little tired. She had never participated in such a strong battle as a frontline combatant, and released two wind healing techniques in succession. Countless healing techniques had exhausted all her magic power. If Gu Cheng had not supported her, she would have almost collapsed to the ground.

This pressure made Sari even unable to bear it. She raised her head and looked at the entrance of the room in front of her. She breathed a sigh of relief after confirming that there would be no more monsters for the time being.

"Mr. Reus, do you want a break for a while?"

"No...bear it, let's leave here now..."

Gu Cheng shook his head. Although he had cleared the skeleton monster here, he always felt a hint of quiet danger. He looked around vigilantly, but he could not figure out where the faint sense of crisis came from in his heart.

"Silver Guardian, holding Sari."

Suddenly, Gu Cheng thought of a very bad possibility!

He immediately walked to the surveillance magic stone position next to the console. Although these magic runes were too old and mostly had expired, it was not difficult for Gu Cheng, who had specially found a guide on the forum. Gu Cheng began to repair the rune arrangement next to the surveillance magic stone. After a moment, the surveillance magic stone gradually lit up. Then a magic projection position was displayed above the surveillance magic stone, showing the location of the entrance of the Mysterious Sanctuary. At the entrance of the dark iron gate, more than a dozen mercenaries holding weapons were fighting against the skeleton warriors from the Mysterious Sanctuary. Behind them, more mercenaries appeared from the entrance of the cave. The mercenary badges on their shoulders were different, and they were obviously not members of the same team.

Gu Cheng didn't believe that these mercenaries accidentally discovered the Mysterious Sanctuary, and then gathered to come in for adventure. You should know that the mercenary group discovered ancient ruins or mysterious areas without markings on the mercenary map. They usually hid and waited until their team had enough strength or sold the information to the guild. Few gathered other mercenary groups to go there together, so these mercenary groups obviously came with them. Obviously, someone sent to track their mercenaries.

What Gu Cheng didn't know was that Merlin had actually confirmed Gu Cheng's identity when he was in Sort City. If the family hadn't recalled him, he would have caught up with him. But Gu Cheng was also very fast. The day after receiving the news from Bis, he took Sali away from the town, which made Merlin send mercenaries who tried to capture him empty.

"Damn it!" Gu Cheng cursed inwardly, thinking that he was still catching up with him?

Sali was also surprised to see the mercenaries and asked, "Mr. Reus, are they?"

"It's just a little trouble. Let's go!" After saying that, Gu Cheng walked to the console, found the switch to control the entrance of the laboratory, and closed the entrance position, but only that door probably couldn't stop these mercenaries for too long.

Not long after walking, Gu Cheng and his two entered the logistics area of ​​the Mysterious Sanctuary. Just as they stepped into the room, they saw two teams of 12 skeleton warriors and mages coming over. So they retreated back to the entrance, wanting to wait for the two skeletons to go to the front and then enter the room. Unexpectedly, the two skeletons walked to the door of the room and came to the corridor and entered the alert state. Gu Cheng dared not hesitate, so he issued an order to the summoned knight, and immediately launched a quick attack on the leading skeletons. He quickly dealt with the two skeleton warriors, and the skeleton monster behind rushed upwards.

"Ro...Mr. Reus!"

Sari was anxious and wanted to use healing techniques to help, but unfortunately the magic power in her body had been exhausted, and even the simplest Holy Feather Priest spell could not be released.

"Wait there!"

It is not difficult to solve the problem of two teams of skeleton monsters Gu Cheng and the summoning knights, but they are afraid that they will waste too much time and let the mercenary group behind catch up. In desperation, both of them are fully fire-powered.

After dealing with the two teams of skeleton monsters, Gu Cheng was so tired that he was about to sit on the ground. But he did not dare to stop and continued to support Sali and continued to walk towards the depths with the summoned knight.

Gu Cheng and the other two kept moving towards the depths of the shelter. The scattered skeleton monsters along the way were solved by Gu Cheng until they passed through the fourth open iron gate entrance, and they were blocked at the end of the passage. Gu Cheng looked for a while, recalling the information about the underground passage of the Mysterious Sanctuary that he found in the forum.
Chapter completed!
