As the wall of fire rises, the last part of the boulder begins to bake.

Also waiting for the boulder to turn red, Ain carefully controlled the output of the magic energy, throwing a Dazon's quenching prison on the boulder.

The wall of fire shook a few times as it suddenly cooled, but Julian, who had already connected to the fourth layer of the net, quickly controlled the wall of fire and stopped it from continuing to collapse.

Crisp voices came one after another, as the wall of fire continued to burn, and Aine chose to use the mage's hand to remove the last layer of boulder.

When a large enough hole appeared in front of the four of them, there was silence.

The smell wafting from that end was scorched by the wall of fire, and it became unreal. But Aine could faintly feel a rancid smell.

Turning his head to look at Julian, the mage saw him and looked at himself with a puzzled expression.

"Prepare to remove the wall of fire...... "Ain quickly blessed himself with various protective spells, pinched the gem enchanted with protective arrows in his arms, and then activated.

Julian glanced at Ain, didn't say anything, and directly dispersed control of the wall of fire.

The flames slowly extinguished in the air, and the air that had not been scorched by the flames slowly entered Ain's nasal cavity.

Breath of the Dead! Aine was taken aback, and his hand, which was not holding the staff, had already pinched the spell casting material that released the light of Mercury.

However, nothing strange has emerged.

"Huh......" The mage was a little incredulous, the four people on his side made such a big move, and they didn't react?

And Julian, who was beside Ain, didn't say a word, and a light of Mercury was sprinkled.

Screams. The screams of the wraiths.

It turned out to be a wraith! Aine couldn't help but feel a little big. Wraiths are disembodied creatures that can hide in the air in the shadows. Doesn't fear physical damage, unless the weapon has a stat like Shine attached to it. In time, it is arcane, and many arcane arts, which are mainly physical attacks, have no effect, and those that can cause relatively large damage are some arcane with light or fire attributes.

As for the attack method of the wraith, it is even simpler, as long as it is touched by the wraith, it is easy to be controlled by its mind. The light one is dizzy and upside down, and the heavy one is the loss of control of the body. In this situation, as long as one person is controlled, it is very difficult to subdue him.

The light from the second layer of Heavenly Mountain is fatal to the damage inflicted on the resentful spirits. When the light cleared, Ain used a spell to find out, but he couldn't find any trace of the spirit.

Using his staff, Ain widened the hole in the boulder a little, and then he was the first to drill through.

Under the light of the light technique, he looked at the various dirt scattered on the ground, and at a glance, it was obvious that the various layers of soil had fallen.

"Be ready to fight at any time." The mage took two steps forward, giving up space for the other three to burrow, and then went on to summon two Celestial Rats, one in front of the other, to explore the way.

In fact, at this time, Aine found that his spell casting materials were not replenished at all, and now the candle heads in his arms were getting fewer and fewer, and it was estimated that he would be able to summon a few more.

"Do you have any extra candles?" When Ain opened his mouth and saw the confused responses of several people, he knew he was wrong.

Where do military mages need to prepare summoning spells? This kind of cannon fodder summon can't play a very good role on the battlefield at all. Many summons look ferocious, but their own sensitivity is not good, and most of them will be besieged and killed as soon as they enter the battlefield.

In the end, it was Julian who pulled out a few small pieces of candles from his spell material bag and handed them to Ain.

As the feedback from the Celestial Rat came back for the time being, Ain blessed himself with another insight through invisibility, and then with a dazzling magical aura, he beckoned the other three and prepared to move on.

"You've already used up more than half of the spell slot, right?" He had barely taken a few steps forward when Julian suddenly asked Ain.

"Well, almost." Naturally, Ain couldn't expose his magic energy pool, so he could only say a few words casually, "I still have some magic items on my own, and I can also use them as supplementary spell slots when the time comes." ”

Julian didn't speak, and went on as usual.

"biu~" There was a sound of breaking through the air, and the bone arrow was nailed to Ain's protective arrow, splashing a ripple of magical energy.

"Be careful!" Aine suddenly spoke up, because at this time he realized that the two Celestial Rats he sent out had not replied to messages for a long time. However, because the spiritual connection has not been disconnected, the mage also feels that nothing will happen.

At this time, several triggering spells that Julian had set on himself were also quickly activated, and the brilliant brilliance of magic energy illuminated this secret passage.

"You shouldn't go ...... here," a hoarse voice was accompanied by a corrosive black ball of magical energy, which slammed into the layer of magical energy outside Julian's body.

"Have you improved the magic missile?" Julian's voice was very calm, "But it seems that your level is not very good, throwing this level of missile spells against the shield technique, is it that you have not learned the basic arcane theory solidly?" ”

Naturally, taunts are taunts, and it is impossible not to fight back with only the mouth gunner. Julian quickly grabbed a handful of materials and threw a string of magic missiles.

The white, glowing magic missile flew in a trajectory into the depths of the secret passage, and soon there was the sound of crashing and shattering bone shelves.

At this time, Duke's spell in the back row had also been completed, and a bag of things came out of his hand, spilling a cloud of glitter dust.

"Since ancient times, migrant workers have many spells, and the world's arcane magic is ...... dust" Ain saw Duke's subconscious handful of flash dust, and couldn't help but crook the corners of his mouth, and complained in his heart.

However, the mage's own movements did not stop, and after checking the protective spell on his body a little, a hot magic ball slowly rolled forward along the ground.

Compared to the brief lighting effects of the magic missile and glitter dust, this fireball rolls slowly, but as long as it rolls over, it can naturally illuminate a tunnel.

However, Ain's idea was quickly shattered, and another black orb accurately hit the hot orb released by the mage, and then the mage was surprised to find that his spell had been countered.

It was only at this time that Aine raised all his vigilance. Originally, he was a little disdainful when he saw the corrosive magic ball thrown on Julian, but this spell counteract clearly showed the strength of this corpse witch.

"Be careful, this corpse witch is not ordinary!" Ain hurriedly spoke.
