In the dark night, there was silence all around, and the old trees were all around, and a few ravens were arranging their feathers on the branches.

Bang!!!

The grass beneath the trees lifted, revealing a black passageway.

Lei Lin was covered in a black robe, covering his face so that he could not see his specific appearance.

There were still a few lights in the manor not far away, and the mercenaries patrolling and guarding did not know that their master had secretly left the manor.

In Lei Lin's real room, there is a secret passage leading to the outside, which is arranged by Lei Lin himself, and no one else knows about it.

"Since that Manxter Giant Serpent is a real yàn body, there must be a wizard's real yàn room nearby! Moreover, that Manxter Giant Serpent has actually been entrenched in the Night Forest for several years, and no wizard has come to recover it, so there is only one possibility!"

Lei Lin's eyes flashed: "That real yàn room should have been abandoned! The wizard inside can't take care of it due to other circumstances, and even has died! That's why the giant snake escaped!"

For wizards, exploring ruins has always been a favorite.

The remnants of ancient wizards, the real yàn rooms of formal wizards, etc., often leave behind a lot of cherished real materials, advanced research disciplines, powerful witchcraft and magic weapons, etc., which are all things that many wizards dream of.

In the rumors, there is no shortage of cases where so-and-so wizard apprentices were originally useless, but later discovered the ruins and began to make a big splash.

Of course, there are also corpses that fail in exploration and end up dying under ancient mechanisms and curses.

But for wizards, exploring the ruins is still a lucrative affair.

For the wizard's room that can create a half-adult Manchem serpent, any bit of anything that flows out of it can make Lei Lin rich immediately, and even obtain a lot of precious materials and knowledge, paving the way for his promotion to a full-fledged wizard in the future.

"Now that I've found traces, I'm going to have to go and see that room!"

Leylin's eyes are determined, and he is not afraid to take risks, especially when the risks are less and the returns are high.

For this expedition, he also prepared a lot of things, which were enough to deal with sudden crises.

As for those subordinates, not only is it easy to leak information and the like, but under the trap of official wizards, even the knight is just a slightly larger ant, which is completely useless, and Lei Lin simply hides it from his own people.

Lei Lin hurried overnight, because there were no outsiders, and many methods could be used.

A cloud of green elixir splashed on the ground, rippling a circle of green wind elemental energy particles, enveloping Lei Lin's body, and his whole person seemed to turn into a breeze and disappear into the night.

What Lei Lin used was the acceleration potion he had configured in the past few years.

As an excellent pharmacist, Lei Lin is very handy in both rushing and fighting with medicine.

The original crypt, where Leylin and the others fought with the Manxter Serpent.

The mutilated limbs on the ground and most of the body of the Manxter Serpent had been carried back to Polar Night City by the people sent by the City Lord's Mansion, leaving only the cratered surface and the remnants of the fire and ice, still telling the fierce battle at the beginning.

"I've recorded the previous situation with a crystal ball issued by the academy, and it's definitely not a problem to prove that the mission has been completed. ”

During the last battle, Leylin used a crystal ball to record most of the quest, especially the corpse of the Manxter Serpent at the end.

With some of the materials on this corpse, plus the record of the crystal ball, it can be said that Leylin's mission in Polar Night City has been successfully completed.

But he had no intention of leaving.

Not to mention that the Black Bone Forest Academy is now in the quagmire of war, even if the winner has been decided, Lei Lin does not want to go back during this time.

He had just successfully developed an alternative formula for Azure Elixir, and it was when he used the potion to propel himself to a third-class apprentice, so how dare he go back to the academy to expose himself now?

And in Polar Night City, Lei Lin didn't see a formal wizard at all, so he could safely carry out the real yàn and promotion.

After three years, the war in the Black Bone Forest Academy must have settled, and with three years as a buffer, although the speed at which Lei Lin was promoted to a third-class apprentice was still very fast, it was not so dazzling!

When the time comes, it's easy to find other excuses.

As for the corpses of the apprentices on the ground, they naturally had already been inspected by Lei Lin and collected all the valuable things before leaving with the seriously injured Jackson and Melfeller.

"But those apprentices are all poor ghosts, and the magic stones are no more than ten at most! only that half-orc wizard apprentice has an ice alchemy rune, which is a good thing!"

Leylin grumbled inwardly as he reached the center of the cavern.

Under the light of the flashing jellyfish above, the entire cavern was very bright, and Leylin could see that on the ground in the center, a circle of track-like traces was visible, which was the trace of the Manxter's long-term entrenchment.

"It's actually pressed such a deep mark, and the Mancaster Giant Serpent is really as lazy as the book says!"

Leylin crouched down and stroked the dirt inside the sigil.

"Chips!"

"It has been recorded that compared with the number of ordinary soil samples in the database, there is 0.005% more material residue in the target, and it is preliminarily judged to be Mike Alloy!"

The chip gives the information.

Mike Alloy is an artificial metal created by wizards using witchcraft, and is widely used to make items such as hatching pools in real rooms.

"Sure enough!" said Leylin's eyes.

"Chip, can you find where this big snake used to be through the snake path?"

"Scanning! The number of targets is covered by a large number of other beast traces, lack of important information, and the mission has failed!"

Relin swept around, and the ground was covered with the claw marks of various beasts, the traces of the parasitic nature of the Manxter Serpent.

"It's a pity......" Leylin shook his head.

"However, judging by the habits and other traces of the Manchter Serpent, that real yàn room must not be far from here!"

Thunderlin commanded the chip: "Chip! Scan all the surrounding scenes!"

"Mission set, start imaging!"

With the sound of the chip, a blue topographic map was projected in front of Thunder Lin.

In the center is a huge cavern, and there are many small tunnels around it, and even Leylin has found a few surviving parasites, and it is not known how long they will survive after being separated from their mothers.

As the topographic map became more and more enlarged, it finally came to an end.

Lei Lin frowned: "Chip, re-scanning, accuracy and the like to the minimum, expand the scanning range, and focus on checking the radiation concentration!"

As the order was given, the topographic map in front of Lei Lin suddenly became a lot blurred, but the scope suddenly expanded, and almost all the surrounding terrain was detected.

"Keep that range and precision!"

Leylin walked out of the cavern and began to run in one direction, and as he moved, the edge of the map expanded......

A few hours later, Leylin came to a large black rock.

"Several places around have been investigated, although the radiation concentration is relatively high, but it should only be the place where the Manxter giant snake used to live and molt!"

"And the only one that has no radiation, but is not within the scope of chip scanning, is only here!"

Leylin looked at the huge black rock in front of him, which was several people tall and almost a small mountain.

In the map scanned by the chip, there was no trace of this stone at all, and even now, when Lei Lin stood in front of the rock, the chip was unaware.

"This situation has only happened a few times in the academy, and it is because of the influence of the witchcraft circle arranged by the official wizard, which will interfere with the operation of the chip!"

Leylin caressed the surface of the black rocks, cold, damp, and parasitic moss and the like.

"But...... How do I get in?"

Lei Lin used a slight force in his right hand to grab a piece of stone powder.

"Chips!

"Ding! mission established, count jù collecting ......" The sound of the chip kept coming, and a light curtain appeared in front of Lei Lin, on which the number of components of the rock was densely recorded.

"It looks no different from ordinary shale!" Lei Lin compared the composition map, and called up the shale composition map in the database for comparison, and finally had to admit that the wizard did a good job of secrecy, and Lei Lin couldn't find the entrance to the real yàn room at all.

"However, since that Manxter serpent can come out, it means that there must be something wrong with the defensive witchcraft circle in this real room, but it still needs time to observe......

Relin touched his chin and set up a tent next to the rocks.

He decided to stay here for a long time, constantly testing the weak points of the defensive circle, hoping to find a way to enter.

Anyway, this area belongs to the area of the withered forest, and after the City Lord's Mansion sends someone to transport back the corpses of the soldiers and apprentices, as well as the remains of the big snake, no one will come here at all.

Leylin ate a few slices of biscuits and the like that he had brought with him, and then fell into the analysis of the rocks covering up the witch array.

Of course, he dared to do this, completely based on his observation and speculation before Tong Guò, and he was already sure that the owner of the real yàn room had abandoned this place a long time ago, and perhaps even the unknown wizard had died a long time ago.

"I've been here for so long, and there are no wizards coming out of the rocks, and the accuracy of this judgment has increased by at least 30%!"

Leylin stared at the black rock in front of him, and a look of fanaticism shot out of his eyes.

"As long as the defensive witch array is eliminated, everything inside is mine!"

A complete full-fledged wizard's room is a great treasure for Lei Lin, who is still a second-class apprentice!!

"It's just...... The arrangement of the official wizard must be extremely terrifying, and I must not be blinded by interests and end up in danger!"
