In the huge cave, the peculiar fishy smell of insects is several times stronger than the outside, almost making Leo unable to penetrate.

But when he saw the mother queen in front of him, he immediately left this feeling behind.

It was a huge spider demon crawling on the ground, at least close to ten meters long and five meters high.

Its body is grayish-white, and it is unknown if it is because it is the same, or because it is close to death, it has changed color. Because Leo felt a strong atmosphere of death from the aura it emanated, maybe it really didn't last long.

In the same way, the Mother Emperor also had two rows of sixteen eyes, and her chelica teeth were not very large, and it was obviously not needed in the Spider Demon clan to participate in the battle. Its belly is very large and has a strong fertility. As far as Leo knew, at least half of the entire spider demon lair was hatched from the eggs it layed.

Sensing Leo coming in, the Spider Mother Queen spoke, "Strange human, I haven't seen you, what did Catherine ask you to do?"

It is huge, but its voice is very soft, and unlike the spider demons it has encountered before, its vocal system is much more advanced, and it sounds a bit like the voice of a human woman.

Of course, Leo knew that Catherine, who had the title of "Magic Bomb", was a high-ranking member of the academy and the head of the battle mage group, and usually mainly complicated the affairs of the spider and demon plane.

"It wasn't Ms. Catherine who asked me to come, but the college sent me. He replied truthfully.

"What are you doing here?" asked the Queen again, her voice weak.

On the way in, Leo had already guessed, so instead of answering the other party's question, he asked, "Your venom, will it cause you harm?"

The Empress was a little surprised, and all eyes were on Leo. After a while, he said, "That's right, I'm too old, I've lost my resistance to venom, and now venom is no longer my weapon, but will make me suffer for a long time." ”

Such an answer is tantamount to confirming Leo's guess. It also made him more and more sure of his judgment.

It seems that this step is to test its ability in the sub-school, but I don't know if other participants have encountered the same situation.

"It's impossible, how can everyone meet the mother queen who is dying of old age. Leo mentally dismissed the idea, and then tentatively said, "May I analyze your venom? ”

"Is that what you're here for?" asked the Queen Queen, confused.

"That's right, that's where I came in. Leo's voice was steady, which made the words seem more convincing.

"It's hard for me to understand. The Mother Mother said, and just as Leo was about to explain the Academy's mission in detail, it added, "But if you can succeed." I don't mind if you do that. ”

Leo didn't expect it to go so well, but it couldn't have been better for him.

Hurriedly taking out the portable alchemy laboratory, he found another problem, how to get the other party's venom?

The Empress saw Leo's hesitation, didn't say anything, and directly opened her chelica teeth, and a large drop of dark green liquid dripped down in the next second. Fell directly on the "ground" of space.

"Zizizi!"

Upon contact with the venom, puffs of smoke rose from the ground made of flesh sacs. It can be seen that this venom is extremely corrosive.

However, Leo then discovers that while the meat sac is corroding, it is also repairing itself, and it is not as fast as it is serving.

At this time, the voice of the mother queen came: "Hurry up and get the venom, otherwise it will be exposed to the outside and it will soon be invalid." ”

"Okay. "Leo is no longer due to. Carefully using a few test tubes, collected as much venom as possible, and placed it on the portable test bench.

Next, there is a series of toxin analysis processes. This is the basic course of the academy, for a qualified alchemist. There is no difficulty, and even the most average students can complete it accurately.

After a while, Leo had already completed the analysis, but he found that although the Venom of the Mother Emperor had most of the ingredients he knew, two of them, he had never encountered at all.

"I've never heard of any other ingredient that can relieve pain, but are these two ingredients that can relieve its pain?" Leo naturally had such a guess, and also had the idea of asking the professor to analyze it.

But he knew that half a day had passed since he entered the spider demon plane, and he really couldn't afford to waste any more time.

Judging from the current situation, these two unknown substances can be arranged in three ways. They are extracted separately from the two substances, and by mixed extraction.

Now that he has found his goal, Leo no longer wastes time and immediately starts to act.

It sounds like a simple job, but it's actually quite complicated to operate, so it took him a full hour to finally complete it.

During the whole process, the Mother Queen didn't make any sound, just didn't know if she was always watching Leo's actions, or if she was resting in the middle of it.

But this was not Leo's concern, looking at the colorless transparent, dark red, and light blue liquids in the test tube in front of him, he really didn't know which one to try first.

"Let's start with the colorless ones, at least they look normal. Leo made a quick decision.

The Mother Emperor was quite cooperative, squirting out a spider silk, which accurately touched the test tube containing the transparent liquid and sent it to her mouth.

Anyway, this liquid is extracted from its own toxin, and even if it doesn't work, I believe it won't make the situation worse.

After a while, the mother's voice sounded with joy: "Thank you! Human! Your things have an effect! I feel much lighter!"

"Haha, that's great!" Leo was very happy to see that he had succeeded on his first attempt, and it seemed that his luck was good, which was a good sign.

He hurriedly took out the nameplate again, and the words on it changed again.

"The third step of the task is complete. ”

"Quest Step 4: With the help of the Spider Demon, go to the ground first, and then go to the fortress of Khost. ”

"To show my gratitude, you can ask me to do one thing for you, as much as I can. The pain was relieved, and the mother's voice sounded much lighter.

And this is exactly what Leo needs, he said without thinking: "I do need your help with one thing, I want to get to the ground first, and then go to the fortress of Khorst, can you help me there?"

"Why did you get to the ground first?" asked the Mother, puzzled. (To be continued.) )
