"Squeak-" Lin Meng came to another door, gently pushed the mottled iron door, and found that the iron door was not closed, but only hidden together. Under the push of his hand, he slowly opened, tightened the items in his hand, Lin Meng stepped in, suddenly, his face turned pale, the first thing that caught his eye was a twisted and decaying corpse, the corpse was facing the door and the body was backwards, the death was twisted, he tried to stretch out one hand forward, grasping the door, as if he wanted to escape.

Lin Meng carefully avoided it, and just as he walked past the corpse, he suddenly paused, and then he bent down and carefully picked up a black object from the ground, which was already covered with floating ash, and he gently wiped it with his hand, and a familiar cross-shaped mark appeared on the surface of the object.

"Sure enough—" He looked at the black badge in his hand, his eyes flashed, and his heart immediately knew that this was clearly the Knights Templar's badge, and he already had one on him, "This is indeed the Templar Order, a former stronghold." He remained silent, put away the badge in his hand, and walked into the room.

The layout of this room is about the same size as the previous room, full of various shelves, Lin Meng also saw dozens of mature black devil insect specimens, but they have all decayed and decayed, and they will be shattered at the slightest touch, which makes him extremely regretful, there are many things he doesn't know left, and even some biological specimens, evil shapes and evil shapes, are very similar to some ancient creatures that have long been extinct in ancient books, and he recognized several ancient creatures with great fame in ancient times, these things have been placed until now, and they have been broken if they are not well preserved, which makes him feel painful.

Half an hour later, he searched the room inside and out, and found no resources that could be used, Lin Meng was full of disappointment, walked out of the room, and it took nearly half a day for him to finish exploring the place near the teleportation array, and after recovering from serious injuries, his body couldn't bear it, and he didn't find anything, so he returned to the room where the teleportation array was located along the road.

Although he didn't know where the other end of the teleportation array was, in this laboratory where he didn't know the roots, Lin Meng acted carefully, for the sake of safety, he chose this room of the teleportation array, as a place to heal, if something was wrong, he would inspire the teleportation array to leave.

Not long ago, after his body was able to move, he experimented and found that this teleportation array was intact, but there was no magic stone to provide energy, so he had a bottom in his heart.

Back in the room, he began a day of meditation, embarking on the path of a wizard, that is, choosing to be accompanied by boredom and loneliness, all these years in the red desert, he has been accustomed to this kind of day of being alone, the 'Black Ink Orchid' potion in his hand, gently drip a drop, he immediately closed his eyes, and slowly mobilized his spiritual power to make them work.

The potion in his hand was only enough for him to take it next time, and then there was no more, and at this time, his spiritual power became extremely active, and the blue mist that was originally floating around the three-dimensional model in the spiritual sea had turned into a dark blue, tightly clustered together, extremely thick, and it seemed that as long as he squeezed it lightly, water would flow out.

Liquefaction of spiritual power——, this is a phenomenon that can only be experienced by a first-level high-level wizard, and Lin Meng's spiritual power at this moment is already extremely thick, and it is not far from liquefaction, as long as all the spiritual power in his spiritual sea is liquefied, then he is a second-level wizard.

The meditation continued until late at night, and it was not until in the depths of Lin Meng's mind that there was a burst of swelling pain, that he woke up from this special state, and then began to practice some secret arts.

There was nothing to say all night, the next day, although after a whole night of meditation and study last night, Lin Meng's mental state was very full, he once again headed towards the ruins, those places he had not been to, and began his adventure, this ruins covered a very huge area, yesterday half a day, Lin Meng only had time, and searched some places around the teleportation array, as for the farther places, he had not been there.

......

Half a year later, the underground ruins.

Lin Meng looked at a black vein in front of him with a happy face, he didn't expect that unintentionally, he would make a huge fortune, this turned out to be a black underworld vein, this discovery made him feel a little unreal, as if he was favored by the gods in the sky.

In the past six months, his injuries have recovered as before, and even his mental power has improved, this suspected laboratory ruins, he has almost explored, and today he found that under this ruins, there is a hidden place, when he came here cautiously, he was shocked.

This turned out to be a huge ore vein, and several branch ore veins composed of black dark stone veins, Lin Meng did not expect that in the exploration of this ruin in the past six months, he did not find anything useful in it, except for those experimental specimens that had long been dried up and abandoned, he did not even find half of some corresponding books and materials, it seemed that the other party retreated extremely resolutely at that time, and directly gave up this huge ruin.

At this time, Lin Meng's face moved, and he casually picked up a black stone from the ground, "Sure enough, it's a black dark stone." His eyes froze, and he recognized the stone in his hand, which was the real Black Stygian Stone, and immediately his heart was overjoyed, and then he thought about the strange spirit he met under the Black Rock Mountain Range last time.

At the beginning, the other party proudly told him that the black demon insect plague that shocked the southern continent in ancient times was caused by their Templar Knights, and now seeing the black underworld stone vein here, Lin Meng was also relieved, but he didn't know whether this vein was originally here, or was moved here by the high-level of the Templar Knights with shocking means, Lin Meng knew that this thing was only produced in the Chiyan Desert in the extreme west.

His spiritual power gushed out wildly, sweeping over the undulating veins in front of him like underground mountains, Lin Meng patted the pet bag on his waist, and suddenly there was a loud buzzing sound, and a black dark cloud gushed out of his head, the dark cloud came and went faster, as soon as it appeared, these giant gold beetles who had just woken up also felt the breath of the black stygian stone, and there was an impatient squeak in his mouth, and a swarm of bees rolled towards the ore veins in front of him.

Countless beetles, pounced on the black underworld stone on the ore vein, Lin Meng breathed a sigh of relief in his heart, this batch of giant golden beetles began to fall into a deep sleep after the trip to the Crimson Tower, and did not wake up until not long ago, and then Lin Meng began to feed them the black underworld stone, but he did not get much black underworld stone in the Red Flame Desert.

He had purchased a batch of them himself, and he had obtained a batch from the Mountain Rock Tribe, as for the Crimson Tower and the Red Flame Desert, several other places that might produce black stygian stones, but he didn't expect that unexpectedly, under this long-abandoned laboratory, there was still a vein of black stygian stones, how could he not be overjoyed.
