Mason arrived at the Leslie clinic on time during work hours, changed into a nurse's gown and started busy.

By the time Dr. Leslie arrived at the clinic in the long due row, the hard-working young intern had already helped more than a dozen patients perform simple debridement and suture procedures.

He even used a spare operating room, with several senior nurses volunteering to be his assistants.

The scene left Dr. Leslie dumbfounded.

This young man she personally recruited to the clinic can bring her a complete surprise every time, seeing Mason wearing a mask and holding a scalpel in the operating room, if you don't talk about the details of this guy, no one will know that he is a wild alchemist who doesn't even have nursing certificates.

But even the demanding and serious Dr. Leslie has to admit that Mason is an absolute expert in his field.

Otherwise, there would be no way to gain such a great reputation in your own clinic in such a short period of time.

The nurses were about to regard this tall, handsome, and kind young man as a group pet and idol.

"I don't think I'll use it anymore."

When Mason walked out of the operating room after another emergency first aid suture, Dr. Leslie, who was wearing a doctor's gown, said quietly with a cup of coffee:

"Maybe in a few months, I'll be able to stay in the office and enjoy the fish... Mason, if I'm not mistaken, you've been fired from me!"

"That's right, you'll pay one less salary."

Mason took off his mask and said with a hippie smile:

"But you can't stop my desire to serve those in need for free, that's what Batman taught me, and I can use my own hands to make this city a better place because of me.

Besides, my first aid skills are getting better and better, and you can be more relaxed.

Gordon has invited you three times in the past half month, so you should probably take some time to reminisce and enjoy the good feeling of love, I mean, you have to at least give the infatuated old man a chance, right?"

"Shut up, you nasty thing!"

The cold-faced doctor pushed his glasses unhappily and said to Mason:

"There are a lot of patients in the emergency room who were injured last night, you go and deal with those who have minor injuries, and I'll come to the emergency room. And also! At noon, I want to try the Provençal fish soup."

"Roger!"

Mason gave a military salute, strode out of the room, and turned back to the smiling Dr. Leslie:

"Doctor, if you don't have any trouble, I'd like to borrow the clinic's pharmacology lab in the afternoon, and I have to make a few potions here that require specialized equipment.

I promise I won't break anything."

"Ding"

A bunch of keys were thrown away, and Dr. Leslie said with a cold face:

"Those instruments were donated by the Wayne family, and they are very expensive, if they are broken, you will find a way to pay for them yourself!"

Mason shrugged as he pinched the key.

It's actually quite good to have such a cold-faced and warm-hearted boss.

However, the phone call he just received was somewhat unpleasant, he didn't know when Talia El Gul got his communication method, but there was no doubt that this kind of private number leakage was as unavoidable as telecom fraud.

"Mason, come on, there's a burn patient in the emergency room! We need your magic poultice."

Wendy, the nurse at the front desk, ran over and shouted to Mason.

The evil alchemist's eyes lit up, the burn ointment he had just made this morning had another tester, which was really wonderful.

After brushing up on the first-aid proficiency in the morning, and using the cooking skills that had reached Lv2 to deliver today's special dish Provencal fish soup to the doctors and nurses at noon, Mason took advantage of the lunch break to come to the pharmacology laboratory on the fourth floor of the clinic.

Normally, this kind of place is used to urgently test the blood composition of poisoned patients, but because Dr. Leslie's clinic has the Wayne family behind it, the "luxury" of this laboratory is not inferior to Wayne Industries

Laboratories of the medical sector.

Basically, all the medical instruments that can be found on the market are available here, and there are three high-speed centrifuges for liquid stratification alone.

Mason rubbed his hands, locked the door, opened the window, and dialed a number.

A few minutes later, the Kite Man appeared in the sky on his kite and landed on the balcony on the fourth floor, handing a black suitcase through the window to Mason.

He said:

"It's not easy to get these things, the old man in that little bar shop has a bad attitude! If I hadn't given your name, he would have almost blasted me out."

"It's a small shop that specializes in spellcasters, and doesn't accept ordinary people."

Mason opened his suitcase and glanced at the various ingredients in it, he nodded, and then said to the kite man outside the window:

"You go to Wayne Manor, get Selena to get the invisibility cloak and wait on the other side of Crime Alley tonight. I received word that a dangerous creature was plotting to attack me."

"I really ate the bear's heart and leopard gall! Does anyone in Gotham still dare to mess with us?"

The kite man was immediately furious, and he said:

"I'm going to set it up over there now, and I'm going to blow up that blind-eyed bastard tonight!"

"Be careful, don't be followed."

Mason reminded:

"That guy is really dangerous, next time I ask John to make you a few tie pins and belts, now we are provoking more and more people, it is really a headache.

Are the vaccines ready?"

"Don't worry, Boss."

The kite man reached out and pulled his V-shaped mask down and said:

"I've rented a special cold storage to store them, and there's only two days left before the 'delivery time' we agreed with the pirates, so we need to hurry, and John, is he still not going this time?"

"He's going to hide from the Stars, so it's better not to show up here for the time being."

Mason looked at the time and gestured to the kite man.

The latter nodded, rolled over and fell down the fourth floor, then glided quickly and disappeared into the gloomy skies of Gotham after the kite opened.

The young man closed the window, processed the various materials brought by the kite man, and then used modern technology for the first time to complete their fusion and further production.

The reason why he didn't use alchemy was because the two things he was going to do today were more unique.

The fear gas of the scarecrow and the neurotoxin of the clown.

Both of these things had been fully formulated in Mason's alchemy branch, and Mason had planned to try them again in a few days, but Talia had somehow alerted him to the Scarlet Knight's attack.

So Mason plans to temporarily upgrade his equipment.

The difficulty with something like fear gas is that it requires specialized equipment to make it.

Compared to alchemy potions, it doesn't test much of one's skills, and it is made according to the standard process of modern industry, as long as the materials are good enough, and the things made are certainly not bad.

Clown toxins are a bit more complicated.

But the equipment at Dr. Leslie's clinic was enough to make it.

However, after reaching Lv4 in the Alchemy Skill, Mason also received "Improvement Suggestions" about the recipes for these two things when he unlocked them.

Obviously, in the evaluation of character cards, both of these things fall into the category of "imperfect".

Mason has processed all kinds of materials that can be enchanted with enchantment skills to improve the quality of the finished product, and he has developed this habit, and in every attempt of all alchemy, the raw materials will be enchanted in advance, which makes Mason's enchantment skills almost like a rocket during this time.

Finally blossoming today!

"Complete a temporary enchantment of excellent crafts and raw materials, and increase enchantment skill proficiency x5, currently at Lv1. Basic Battle Enchantment Blueprint unlocked."

"Cool!"

Mason whistled.

An hour and a half later, as the liquid vaporization instrument was turned off, Mason was given the finished product of a fist-sized small silver-gray gas canister.

He put this thing in front of his eyes, and the information label quickly popped up:

Scarecrow's fear gas

Quality: Excellent alchemy items and excellent craftsmanship

Item Effect: Releases poison gas to stimulate the brain secretion of surrounding life, causing it to enter a state of [Fear] and [Illusion], and the duration of this effect is related to the target's willpower.

When used in large quantities, it will irreversibly damage the target's mind.

Maker: Mason Cooper

Item description: Haunted house play, entertainment for couples, and a great companion for watching horror movies.

Successfully completed an excellent craft, excellent quality alchemy compound production, and the alchemy skill proficiency was increased by X10.

Mason shook the canister twice and then took out the penguin umbrella and loaded it into the delicate mechanical box inside the umbrella.

This umbrella was badly damaged before.

Now, in Mason's renovation and restoration, most of the functions have finally been restored, and even the bulletproof umbrella surface has been remade with Batman's polymer cape material.

Mason plans to take the time to replace the handle with Maxi Zeus's lightning scepter before leaving work, so that the umbrella loses its firing function and has the effect of throwing out high-voltage currents.

The Penguins who are already in Heaven will probably be very relieved to see their ingenuity transformed into this "lethal weapon" by Mason, a Lv3 engineer, right?

As for the reason why Mason had to keep this umbrella, it is also very simple.

Although he now has a variety of lethal weapons to choose from, he can't usually patrol the streets with a shotgun on his back when he shows up as an ordinary person, right?

There must be a weapon that can be used in the "normal form".

Before the break was over, Mason made five canisters of fear gas to keep in his bags and a bottle of clown toxin.

This thing is worthy of being something that Zhou Keer used to harm people.

When it is extracted into a liquid, it is an ominous dark greenish black, and it is highly toxic at first glance.

Clown toxin

Quality: Excellent alchemy items, excellent quality

Item Effect: Depending on the dosage used, it can cause five different effects: [Trance], [Fear and Confusion], [Grumpy Madness], [Sick Madness], and [Deadly Smile].

The item can be spread on a large scale by heating and vaporizing.

Maker: Mason Cooper

Item Description: It's sweet, like the chaotic delicacy you can taste when you decide to abandon your sanity altogether after a bad day.

Successfully completed an excellent craftsmanship and excellent quality alchemy compound production, and the alchemy skill proficiency was increased by X20.

"This thing is a new hole card, throw it out when you are in trouble, you don't even have to clean up the battlefield, it's clean and hygienic."

Mason cautiously put the dark green liquid in his bag, then cleaned the lab and returned to work.

He had a really fulfilling day, thanks to the Assassins' League's ruckus in Gotham City, which made Mason expect the clinic to be very "lively" for the next few days.

Before leaving work, he used magic fire and engineering skills to polish and assemble Maxi Zeus's lightning scepter and replace it with the penguin umbrella, so that Mason's rinsing and transformation of the umbrella was almost complete.

It is still a creation of fine quality, but the craftsmanship has entered the category of outstanding craftsmanship.

Mason plans to take the next step by reading through the blueprints of Mr. Freeze's Freeze Gun, and then add the freeze function to the umbrella, and the flamethrower can be removed.

Mason could have replaced the Spitfire with an alchemy bomb, and that was the next stage of his in-depth research in the field of the fusion of engineering and alchemy.

In the evening, Mason, who had changed back into a gray trench coat, carried a suitcase with a black appearance, gold

The umbrella with the handle of the colored umbrella walked out of the clinic.

The hell started to rain again, but fortunately, Mason had an umbrella and was very gentlemanly to send the little nurse Wendy across the street to let her get into a taxi and leave, and then he walked in the direction of Crime Alley.

Anyway, that cute little nurse always seems to take the initiative to talk to him lately...

It doesn't seem good to go on like this.

As a guy who looks 17 years old but has a soul age of 30, Mason is no longer as enthusiastic about emotional matters as young people.

Although his healthy body tells him every day that he needs it.

But his soul is saying no!

"A good girl should be matched with a really good man, just forget it, an unlucky guy like me who is full of secrets and is unlucky and always strays into the black riot organization."

Mason walked into the dead silence and gloomy alley of crime under the rain, carrying a bag of trash in his hand as if he was about to throw it in the trash.

Ten seconds later, when Mason turned around, at the entrance of Crime Alley in front of him, under the increasingly majestic rain, a guy in a tramp's cloak was already blocking there.

Silently, like a ghost.

He had two black pistols stuck in his waist, and the undisguised emaciated cheeks of the rain were somewhat similar to Mason under the umbrella.

"Jason Todd."

The young man looked at the uninvited guest and whispered:

"We don't have any personal vendettas, do we? You don't go to Wayne Manor to trouble Bruce, why are you blocking me here? You hate the young men who robbed you of Robin's identity, but I turned down Bruce's offer.

I'm not interested in being Robin."

"You killed the Joker."

Jason's hand grasped the gun at his waist and said in a cold voice:

"That's my prey!"

"Alas, it's really unreasonable to talk to you young people with serious family problems!"

Mason complained:

"I always like to force the people I care about to make some stupid choices to confirm your status in their hearts, but you are young and impulsive, and you can't understand that every time you push them away from you.

It's like a throwing knife pierced in the heart, full of cracks.

Oh yes.

I have one more thing to ask you."

The young man coughed, put away his umbrella, and let the cold rain fall on his black hair, he looked at Jason, moved his fingers, and his tone cooled.

He said:

"You're deliberately using Barbara? Or was it just an accident that she was picked up by Grayson to get back to base?"

"Does it make any difference?"

Jason drew two pistols and strode towards Mason.

He asked in the rain.

Mason shrugged his shoulders and fingers on the handle of the umbrella, and replied in a gentle tone:

"Of course there is a difference, and a big difference. This answer will directly determine whether you are being dragged out of this alley lying down? Or was he shoveled out with a shovel ...

So, answer seriously, Jason Todd."
