The underground world is dim and abnormal, but fortunately, there are some minerals such as fluorite in these passages, which emit a faint light through the underground fire element, plus Tang Lin's own magical power, so he quickly found the shaft and climbed up along the wall of the shaft.

At the end of the shaft is a narrow stone crevice, and fortunately, Tang Lin is not an adult now, and it may be that life was not good when he was in the countryside, so he is a little thin, otherwise, he may not be able to get out!

Passing through the gap, Tang Lin spotted a few goblin warriors patrolling, but Tang Lin didn't feel any threat from them.

Even the Spirit Ball Baby said that those guys were rookies, and he had heard a very important news, those warriors said in small talk that most of the garrison here had been taken away, and even the elder who was guarding here had left.

This news couldn't be better for Tang Lin, although there were more than a dozen guards here, and they were all equipped with magic crystal weapons, but these guys were obviously not trusted by Husper, and it could be heard from their complaints.

It's right to think that this place is like an unreachable piece of meat to Husper, and over time his enthusiasm runs out, and he sends some goblins who don't pay much attention to it to come here to make a show.

Now he is in dire need of help, and he has drawn people from here who he thinks are credible to participate in the siege operation, and once again sifted out these goblins, how can they be mentally balanced.

After seeing this kind of guarding power, Tang Lin decided not to go deeper for the time being, he wanted to go back to discuss with Irina a way to quietly solve the other party.

After getting the above details, Irina put away the crystal spear and told Tang Lin that both life mages and wood mages can use a Sleeping Charm, but this Sleeping Charm can only be cast at close range.

"Looks like we need a bait!" Tang Lin groaned as he touched his chin, both he and Irina could cast the Sleeping Spell, but to take down all the goblins above, they needed to get close to them and get them together!

In the end, Mogg volunteered to stand up, saying that he was willing to be the bait, and in order to reassure Tang Lin, he also controlled the armor to change its form, turning into the armor style of an ordinary goblin warrior.

"You're tall now, and in order to prevent them from seeing through, you have to learn to hide your head and show your tail, so let's use this shaft exit as a trap to lure them over!"

After making his decision, Tang Lin asked Mogg to climb up first, and then he and Irina hid in the shaft, just waiting for Mogg to lure the goblin warriors over.

"Help!"

Mogg covered his face with armor over his face, and poked through the gap, shouting in a very faint voice.

The nearby goblins immediately discovered the source of the sound and immediately rushed over, but unfortunately there were only four goblins.

Seeing this, Mogg thought of a plan in a flash, he controlled his armor to probe some barbs to hook the stone cracks, and then stretched out a hand to let the goblins pull him.

"What's the matter, brother, why are you stuck here!" a goblin stared at Mogg cautiously, not immediately rescuing.

"I'm also inexplicable, I'm searching for defectors underground, suddenly the veins shook, I ran lifelessly, I saw this gap and drilled out, I didn't expect it to be stuck!" Mog replied, and the goblins on the other side gradually let down their guard.

"Come, brothers, pull this unfortunate bastard out!"

With his order, several goblins immediately turned on the carrot pulling mode, but how could Mogg let them get their wish, so in the end it could only be in vain.

"You haven't eaten, call more companions over!" Seeing that the time was almost up, Mogg pretended to be angry and yelled.

"Wait, I still don't believe it, this stone crack can still bite you to death!"

This goblin is very good, and immediately went to call friends, this time is the time of boredom, as soon as the goblins heard that there is such a thing that can be entertained, Hula La ran over.

When they were all gathered around the entrance of the cave, Mogg kicked the cave wall to signal Tang Lin and them.

Irina took the lead, she silently recited the spell, the life mana was instantly released, and the sleeping spell hit the goblins who were surrounding the entrance of the cave, and Tang Lin was unwilling to follow, and he also cast magic very quickly, and in less than a few blinks of an eye, more than a dozen goblins lay on the ground.

Of course, there are also those who are highly resistant to magic, although they are dazed, but they are not completely asleep, but it doesn't matter, because they were quickly physically knocked unconscious by the three goblin brothers who came out.

"Let's go, go around this passage, the door of the material institute is on the other side!" After Mo Du tied up the dozen guys firmly, he took Tang Lin towards the gate of the material institute.

After turning around a lot, Tang Lin finally saw the so-called gate of the material institute, there was a huge space here, and there was a metal gate in the innermost part of the space, more than thirty meters high and seven or eight meters wide, tightly inlaid on the stone wall.

"Big brother, go ahead, only you can pass through the defense array in front of the door and turn off the general control of the defensive weapon from the inside!"

Mordo glanced at Mogg and pointed to the mirror-smooth ground in front of the door, which shimmered with mottled dots of light.

As far as he knew, if the entrant didn't have the Goblin Clan Order and the Goblin Battle Armor, as long as he stepped into that area, even if you were a saint-level master, he would be killed on the spot.

"Okay, look at me!"

With the token in his hand and his armor on his body, Mogg stepped cautiously on the ground, and those points of light suddenly turned into beams of light, beginning to scan his body and detect the token at the same time.

"Look, my lord!" Mordo grabbed a stone from the ground and threw it, and in the blink of an eye, the dense beams of light instantly burned the stone into a sheet of powder.

"Third brother, don't do this, the eldest brother is still inside!" Morry scolded with a smile, and then saw Mogg speed up his pace and rush through the area.

When he placed the token in the stone statue groove by the door, the beams quickly retracted, turned into points of light, and then disappeared completely.

"My lord, let's go, the defense array is closed!" Mordo quickly stepped onto the smooth ground, as if he was fighting for Tang Lin.

"Let's go, go and see the treasure of this goblin clan!" Tang Lin took Irina's hand and boldly walked to the door, sure enough, nothing happened.

And as they walked towards the door, Mogg began to turn the token, and with a crisp sound, the door slowly opened.

There was no dazzling jewels in his face, and there were no compelling fluctuations of magic elements, and Tang Lin even smelled the smell of metal rust.

After following the three brothers into the gate, there was a staircase that went diagonally downward, and as they stepped on, some very special tools automatically glowed, illuminating the inside clearly.

Then, Tang Lin saw transparent squares engraved with magic patterns, large or small, displayed on the low stone pillars, and looked at it, he always felt that there were probably tens of thousands of such squares in this material.

"My lord, those transparent cubes are soft crystals, specially used to preserve precious materials, with their confinement, those materials will not have any loss of energy, what they look like when they are put in, and what they look like when they are taken out!"

Mo Du looked at Tang Lin with a puzzled expression, and immediately solved his doubts, and a very peculiar sense of pride also arose.

"Mog, isn't the goblin clan order also able to store things, you look at the outfit, first choose the materials that can cast the armor on your body, and of course, the materials for casting the magic crystal cannon!"

Tang Lin was shocked for a moment and finally returned to consciousness, his heart was full of ecstasy, and he began to act with the attitude of pretending as much as he could.

Irina also opened her bracelet and joined the search, and in a short time, nearly a third of the precious materials disappeared into the space of this material room.

"Dad, you go inside, there are good things in it!" The spirit ball baby, who didn't make a sound after pointing the way, suddenly spoke, and the small appearance was still very excited, Tang Lin naturally knew that she had found something good, so he didn't ask much, and ran forward directly.

Eventually, he stood still in front of a large soft crystal, looking at what was in front of him very strangely.

It was a giant soft crystal that was nearly five meters long, wide, and high, but its interior was only a thumb-sized fragment.

Tang Lin was about to take a closer look at this thing, when the broken token he put in his arms flew out with a whoosh and went directly into the soft crystal.

When Tang Lin took it out again, the small fragment turned out to be one with the token.
