"30 grams of fire-sorred bone powder, 16 grams of lime, 50 grams of ruby powder......"

Bang!

A flame erupted from the cauldron, interrupting the young wizard's muttering, and the entire laboratory was filled with a scorching breath.

Why do you say 'again'...... Mei Lin shook her head helplessly, and said to herself: "There must be no problem with the formula, and the process of preparing the neutralization liquid is also strictly in accordance with the programmer's instructions, why does the material explode as soon as it is added?" The refining of the first few potions is very successful, why has this potion been refined more than twenty times, and it still fails?"

Half a year later, in addition to her normal meditation, she had chosen two second-level witchcraft from the treasures of the Valley of Mystery Academy, one was 'Chain Lightning' and the other was 'Flame Burst', and in addition, she was studying the inheritance of the potion.

After successfully refining several low-level potions, Merlin planned to increase the difficulty, but now it seems that her previous idea was too optimistic, if not the material problem later, it is still the problem of the neutralizer.

However, there are several materials that are almost used and need to be supplemented.

No sooner had she returned to the valley hut than she heard someone outside asking to see her.

"Why did this guy Langdon come here in person today? But it just so happened that the lack of these materials was just right for him to replenish. Merlin chuckled softly.

After a while, Langdon stood in front of Merlin, a worried look on his face.

"Something seems to be happening? Merlin said lightly.

"Ask for your help......" Langdon said respectfully.

"Be clear. Merlin was a little impatient.

"Yes. Langdon replied, and elaborated on what he meant.

Just three days ago, several miners hired by the Carenzo family had been attacked in an abandoned mine, and after the news broke, a patrol of the Carenzo family went to investigate, and in the same cave, a patrol of more than twenty people (including a wizard apprentice), all but one of the scouts had died in the cave.

"What didn't the scout see?" Merlin asked calmly.

"Nope. The scout didn't make it to the hole because he sprained his ankle in the previous action, but he heard the screams of his teammates and the roar of the behemoth outside the hole. Langdon said.

"What about your father? he didn't confirm it?" asked Merlin.

"Father, who had recently been away from the castle, had been invited by a friend to explore a ruin. Langdon replied, "It can't be hidden, and now all the mines are forced to stop, and the workers don't dare to do it any longer." ”

This is a problem, after all, Merlin has to collect 20,000 magic stones every year. If the Carenzo family's income suffers, Merlin will also suffer.

"Okay, you arrange for someone to show me the way. Merlin said after a moment's silence, a little curious about what it was.

......

Although Merlin, the elder of the Black Tower, was the main force in battle, Langdon still sent four great swordsmen from his family to accompany her. When Merlin rode the flying golem leisurely in the air, the warriors at her feet all looked at the wizard in the air with envy.

"Wizard...... It's really comfortable, even such a short road has to fly. Karl chuckled.

"You wait. It's just you...... Even the armor with more than 200 catties of stinky meat, what kind of flying puppet can't carry you. Seville smiled with her mouth covered, she was the only female swordsman of the four.

"Hmm, Sevelli, you're half a wizard, what do you think of that elder?" the other great swordsman asked curiously.

"Unfathomable. Severi said with some uncertainty.

One hundred and fifty meters ahead is the entrance to the abandoned mine, and no signs of living things have been found. "Responsible for serving as a scout...... That is, the guy who was in the patrol team was completely wiped out, and hurried back to report it.

"Stand still. Merlin was the commander of the operation, and she waved her right hand to signal everyone to dismount and rest, and she herself controlled the flying golem to fall to the ground.

"My lord, I'll take someone in to check on the situation. Lawrence, the Great Swordsman, asked.

"There's no need to risk it. Merlin shook her head, took out an alchemy puppet from the dimensional ring, and then lightly gestured twice on its body, this alchemy puppet immediately opened its crystal eyes, and looked around blankly, "Just let it go in and take a look, it's just a matter of being ambushed by a group of humans, if you send it to the mouth of the beast, it will be a little stupid." ”

Although Merlin had no intention, she was suspected of firing a map cannon, and a whole patrol team had been killed in the mine before.

Mei Lin was also an afterthought of the embarrassment of several great swordsmen, although she felt a little embarrassed, she had no idea of apologizing...... Besides, in her opinion, those people are really stupid enough, in this environment, they actually entered the mine together, didn't it give people a chance to end the pot.

This alchemy puppet is about a meter tall, boxy, and has four legs underneath, and walks very steadily...... Of course, as a first visit, gifts are inevitable, and Merlin amicably places a goblin bomb behind the golem, which allows it to enter the cave.

The alchemy golem walked steadily into the pitch-black cavern, its crystal-made eyes glittering with a dim light, guiding it forward.

"This alchemy puppet has a wizard's eye sealed in its eyes, it will self-destruct when it encounters danger, it has a goblin bomb on its back, once it encounters danger, it will immediately detonate the bomb, even if it can't be blown up, it can take half a life. "Let's take a break and see what's inside." ”

After a long time, there was no unusual noise in the mine, and the great swordsman Lawrence couldn't stand still, and asked, "Lord Merlin, let me go in and take a look!"

"No hurry, wait. Merlin's face became solemn.

Through the wizard's eye worn by the golem, she was able to see things that others couldn't...... About a kilometer or so from the mine, there were some skeletons that were clearly human, and none of them were complete, and there were some tools and weapons used by humans on the ground.

Rumble!

Half an hour later, a huge black shadow suddenly covered the alchemy puppet, and then a dull loud bang came out of the mine, and the ground also shook violently. At the entrance to the mine, rubble and mud fell in a torrent, as if the entire mine was about to collapse.

"Prepare for battle!" Merlin looked at each other and ordered in a low voice, and the four great swordsmen immediately drew their swords to prepare, as for the scout, he had already been ordered to hide in the jungle in the distance.
