I can see experience bars after being transported to another world.

Lu Yuan gazed at Mary, his thoughts sinking into the depths of his mind. [Forbidden Studies - Specialization] had been activated.

The gray and white text danced wildly on my retina, and countless pharmacological combinations began to emerge.

[Analyzing target characteristics: Damaged sanity (depth) + trace amounts of deep-sea pollution residue]

[Formula being derived...]

[Solution Generation: Purifying Sedative (Special Version)]

[Principle: The essence of the Silver Grass neutralizes the source of pollution, the extract of the Calming Flower stabilizes the mental barrier, and intermediate-grade holy water acts as a solvent to catalyze the purification reaction. The three work synergistically to suppress fluctuations in rationality while eliminating trace amounts of pollution.]

[Estimated success rate: 67%]

[Note: The extract of *Calmheart Flower* must be extracted at low temperature, otherwise the active ingredients will evaporate; the extract of *Gynostemma pentaphyllum* must be ground until there are no particles; when mixing the three, continuous stirring is required, and the mixture should not be left to stand for more than ten seconds, otherwise it will produce a highly toxic substance.]

Lu Yuan opened his eyes.

Do you have calming flowers here?

The doctor paused for a moment, then said, "Yes, but that stuff is generally not mixed with holy water..."

"Go get it." Lu Yuan's tone left no room for negotiation. "Also, the Silver Grass, the freshest one. Prepare the mortar and pestle, and the containers."

The doctor hesitated for a moment, but thinking of Lu Yuan's performance at the base and Mary's pained expression, he turned around to get the materials.

A moment later, everything was placed on the table.

Lu Yuan rolled up his sleeves and began to work.

He first put the silver grass into the mortar and ground it vigorously.

The stems and leaves of this herb contain a lot of fiber and must be thoroughly crushed to release its active ingredients.

A faint silvery sheen gradually appeared in the mortar, and a refreshing aroma wafted out.

"Close the window," Lu Yuan said without looking up. "The Tranquil Flower is sensitive to heat, so the temperature can't be too high when we extract it later."

The doctor did as instructed.

Lu Yuan poured the ground Silver Grass essence into a glass container, then picked up the Tranquilizing Flower.

This is a pale blue flower with petals as thin as cicada wings, almost transparent in the light.

He carefully plucked the petals, placed them in another container, added a small amount of water, and then gently stirred them.

The petals slowly dissolved in the water, releasing a pale blue liquid.

"Holy water." Lu Yuan stretched out his hand.

The doctor handed over a bottle of intermediate-grade holy water.

Lu Yuan opened the bottle and poured the holy water into the container containing the essence of the Light Silver Grass. Then, while stirring, he slowly added the extract of the Tranquil Heart Flower.

The three liquids blended together in the glass container, and the color gradually changed from initially cloudy to clear, eventually showing a light silvery blue.

The entire process cannot be interrupted.

Lu Yuan's wrist maintained a steady rhythm, and the stirring rod drew eddies in the container.

"alright."

He stopped what he was doing and held the container up to the light to examine it.

The liquid is clear and transparent, without sediment or separation.

[Successfully completed!]

[Item Obtained: Purifying Tranquilizer]

[Effect: Can neutralize trace amounts of deep-sea pollution, while slowly restoring the resulting loss of sanity.]

[Pharmacology: +0.5, 14/50]

Lu Yuan poured the medicine into a clean medicine bottle, walked to the bedside, lifted Mary's head, and brought the bottle to her lips.

"Drink it."

Mary's consciousness was still hazy, but her body reacted instinctively, and the pale silver-blue liquid slowly flowed into her mouth and slid down her throat.

A few seconds later, her tightly furrowed brows gradually relaxed, her rapid breathing became much calmer, and the unnatural paleness on her face slowly faded.

The doctor looked at this scene with surprise in his eyes.

"How do you know she still has contamination? A standard diagnosis wouldn't show it..."

"I've studied similar cases before." Lu Yuan put Mary back on the pillow and casually said, "Continue to observe. If the situation changes, call me immediately."

Lu Yuan didn't explain further, turned around and walked out of the medical room. Now that Mary was out of danger, he would go and see how Mina was doing.

Just as I reached the end of the corridor, I heard a series of noisy footsteps coming from outside.

Lu Yuan looked up and saw Hans leading a group of Night's Watchmen pouring in through the main gate.

They were withdrawn from the outer battlefields, and each of them bore more or less scars.

Some people's clothes were corroded with large holes by the blood swamp, and others were walking with a limp, clearly having injured their legs.

But what really caught Lu Yuan's attention was their mental state.

Some people's hands were trembling, but they gripped their weapons tightly and couldn't let go.

Some people had unfocused eyes, and some even started muttering to themselves, muttering something unintelligible, occasionally letting out a few suppressed laughs.

Their reason wavered; they were all corrupted to varying degrees.

Hans walked at the front, blood seeping through the bandage on his left arm, but he was still relatively lucid. When he saw Lu Yuan, he nodded slightly.

"Iris and the others are gone?"

"They just left." Lu Yuan glanced at the night watchmen who looked unwell. "These people need treatment."

"We've already used it on them," Hans said, frowning. "But it's not very effective; ordinary sedatives don't seem to work."

He paused, then added, "I've already instructed the pharmacist to expedite the preparation of the new medicine."

Lu Yuan looked around and saw that the night watchmen were all covered in varying degrees of gray mist.

Similar to Mary's situation, it wasn't just a matter of sanity depletion, but also sanity contamination. Ordinary tranquilizers could only alleviate the fluctuations in sanity, but couldn't remove the lingering aura of the deep sea.

"I'll go get the medicine," Lu Yuan said after thinking for a moment. "I have a medicine that can deal with this situation."

"You have a way?" A hint of surprise flashed in Hans's eyes.

"Give it a try." Lu Yuan didn't explain further and turned to walk towards the pharmacy.

The apothecary was filled with all sorts of materials, and the shelves were covered with bottles and jars of all sizes. The air was thick with the mixed scents of herbs and alchemical reagents.

Lu Yuan wasted no time and started working immediately.

With the use of Silver Grass, Tranquil Flower, and Intermediate Holy Water, plus the fact that he had already done it once, his technique had become much more proficient.

Grinding, extraction, mixing, stirring.

First bottle, three minutes.

The second bottle, two and a half cents.

The third bottle, two minutes.

Lu Yuan's movements became faster and faster, but every step remained precise.

[Pharmacology: +0.2...+0.2...15.6/50.]

As expected, experience dwindled, eventually falling below even 0.1.

Lu Yuan discovered long ago that once you master the making of a certain potion, the experience gained from repeated making will be greatly reduced.

But now is not the time to dwell on that.

Half an hour later, twelve bottles of purifying tranquilizer were placed on the table. If diluted, each of the Night Watchmen in the base could have a sip.

Of course, even diluted, it would be enough to relieve the symptoms, since their contamination was different from Mary's—one was contaminated by a collision, and the other was only slightly contaminated.

Lu Yuan put the medicine into a wooden box and walked out of the medicine room.

In the corridor, the night watchmen had been seated against the wall, and Hans had given them medium-grade holy water to temporarily alleviate their condition.

Upon seeing Lu Yuan emerge, Hans quickly approached him. After all, Lu Yuan had joined the Night's Watch as a doctor, and given the previous attack on the base, the medical skills Lu Yuan had demonstrated were indeed trustworthy.

"It's ready." Lu Yuan handed Hans the wooden box before he could speak. "For minor cases, dilute with water; for serious cases, give them the whole bottle. After they finish, have them rest. If anyone is still not feeling well after four hours, give them another bottle."

Hans took the wooden box, glanced at the neatly arranged medicine bottles inside, and a hint of surprise flashed in his eyes.
