Mason returned to his small shop with a full harvest.

He's ready to make a big swing tonight by trying to craft a quasar gun, which can be used as his melee defense weapon to replace the engineering gun that can't keep up with the "version".

But the plan can't keep up with the changes.

Mason, who had returned in a good mood, smelled a rather bad smell coming from the alchemy room in the basement of the small shop, and the smell was like some kind of potion being boiled.

It's all herbs that don't smell too bad, but when they are combined and inhaled, they feel dizzy.

The young man sighed, probably understanding what was happening.

He shuffled to the basement door, reached out and knocked on it, then heard a clanging sound inside, and then Dr. Halle, with a sinister face, opened the door for him with a sneer.

Dr. Hallie changed into a lounge suit, and the small white tank top was propped up by a well-developed chest, which made Mason look away immediately.

Then he saw the alchemy cauldron burning with black smoke and the poison ivy girl Ivy Ivy standing by the pot scrambling to cover up the "incriminating evidence".

"Let me guess."

Mason rolled up his sleeves and said:

"You added calla lily and aconite grass to the alchemy solution in a ratio of three to five without treating it in advance, resulting in a wonderful "alchemical reaction" between calla lily seeds and the already poisonous aconite grass.

In my experience, you won't be left with more than two seconds to react.

It's a shame that you didn't manage to catch this crucial time and this pot of medicine was completely wasted."

"Exactly!"

Dr. Hallie, who was following Mason, stuck out his tongue and whispered:

"I told Ivy that I should take those strange lotus seeds down first, but she wouldn't listen to me."

"It's okay, this is a common mistake for novice alchemists, and I've come from that stage."

Mason didn't blame Ivy for looking lost, but picked up the jar for disposing of waste medicine and quickly cleaned the alchemy cauldron, and took Old K's alchemy notes.

Say to Ivy:

"Look, there's a red line here.

It is very important to tell you about this step and be sure to follow the steps. Although alchemy is alien to modern science, it is also a skill that requires precision.

The handling of materials is also very important, which I will teach later.

Now, Ivy, try again."

Pointing to the various materials on the table, Mason said to Poison Ivy:

"You may be able to start with the simplest alchemy solution, which is the foundation of the foundation in the subsequent study."

"I'll take the liberty of asking."

While handling the raw materials honestly, Ivy whispered:

"How long will it take for me to learn to make those three potions that regulate my emotions and thoughts on my own?"

"Well, that depends on talent."

Mason rubbed his chin and thought about it, and gave an optimistic answer:

"Based on your perfect phase of plants, I estimate that you will be able to try making tranquilizers in a maximum of three months, and the more difficult euphorics and extremely complex palliatives may take half a year or more."

"What about you?"

Dr. Hallie, who was staring at the side, asked curiously:

"Mason, how long did it take you to learn this?"

"Fifteen days."

Mason replied truthfully:

"This is a special case for me, after all, people and human talents cannot be generalized."

This seemingly modest but actually Versailles answer made Hallie and Ivy look at each other.

But as far as the two of them were concerned about their experiences of secretly trying alchemy in Mason's absence for the past two days, they didn't think Mason was bragging or exaggerating the difficulty of the technique.

It's really hard.

Especially in the absence of scientific measurement of time, everything is carried out according to the arbitrariness and freedom of the mind, it is like a child's play.

But there is ancient wisdom in this nonsense.

Mason could make two good vials of blood tonic for the same ingredient, but Ivy would only get a pot of toxic black smoke residue.

Over the next half-hour, Mason personally demonstrated the standard steps of alchemy to Ivy and taught her how to time her using four different sizes of hourglasses.

This is not mandatory.

Of course, clocks and timers can be used instead, but Mason feels that using an hourglass is more ceremonial and more in line with the mystical atmosphere of alchemy.

He told Ivy not to practice too late and left the basement to enter the suitcase space to see what was going on, when Dr. Halle, who had been a temporary watchwoman at Cooper's shop before entering, suddenly told him:

"In the early morning, a very handsome guy brought this box of medicines, and Ivy checked them for strange materials."

Pointing to the box behind the counter, she said to Mason:

"That guy asked me to convey my thanks to you."

"Don't worry about that infatuated guy."

Mason picked up the box and glanced at Hallie, who was sitting behind the counter playing on her phone, and asked:

"What about you? How's your situation? Do you have Halle Quinn talking to you in your head?"

"Not that exaggerated, Mason!"

Dr. Hallie snorted, pushed her glasses, and said academically:

"And the psychological description is not like that, I'm not a split personality, Mason, it's just a psychological suggestion that only works in certain situations.

Ivy accompanied me to Dr. Leslie's office this morning, and that's what the cool doctor told me.

I need to go to her twice a week for counseling, and I feel like I can do it myself, since Dr. Leslie is a major in surgery.

And I'm a serious psychologist."

"Anything related to Zhou Ke'er should not be treated so easily."

Mason shook his head and said:

"If there is anything uncomfortable, drink the medicine immediately, I will keep three bottles of medicine at the counter for you at all times. I'll ask you to help me look after the store tonight, and I can rest until 12 o'clock.

Oh, by the way, don't mess around with this box when I get in, I'll know if I knock on the lid when something happens."

"Huh? What are you talking about?"

Dr. Hallie was confused.

She couldn't understand Mason's words until she saw Mason open his suitcase and jump in with the medicine box.

The psychologist rubbed his eyes.

She watched the retro suitcase "swallow" Mason like a monster, and she immediately felt that her three views, which were no longer so stable, had been impacted.

She felt her stress rise.

So she decisively opened the dark compartment on the counter, took out a bottle of palliative and poured it into her mouth.

"Well, Harry, that's nothing surprising, it's just magic."

She patted herself on the cheek and said to herself:

"Haven't you seen anyone use magic before? Uh, I really haven't seen it before, hey, this young man who is ten years younger than me is really mysterious!

How many interesting things is he still hiding?

This Mr. K is much more mysterious than Mr. J."

---

"Boss, you're finally here!"

The Kite Man, who had been waiting in the box for a day and a night, immediately perked up when he saw Mason enter the space. He put down the wrench and screwdriver in his hand, put the half-modified jetpack there, got up and said to Mason:

"You'll have to look at Jason Todd, that Kryptonian treatment pod can't seem to deal with such an injury."

"Wouldn't it? Is it that serious?"

Mason put down the medicine box in his hand,

Follow the kite man to the location where the treatment chamber is stored.

Before, this space was not so big when there was Lao K's magic apartment, but now that the magic apartment has been abandoned to Zakang as a mage tower, it has completely emptied this place.

Things from Batman's lab and the Batcave are messily thrown around, and on the edge are chained with the three-headed dog Fur, the zombie canine Tooth, and Miss McGonagall, who is fostered here by Selena.

The best Miss McGonagall doesn't have to live in a cage anymore.

Mason saw it dozing off on the head of the Fenrir Warframe prototype.

On top of that, there are a lot of materials from the Caribbean world, and the Devil's Box is thrown on top of a pile of jewelry.

For Mason, who likes to keep things organized, the chaos is a bit uncomfortable, and perhaps he should take some time to plan the structure of the space later.

At a height of 50 meters, you can create at least 10 floors of the area, so as not to waste this space.

"Hmm, haven't healed yet?"

Mason stood in front of the Kryptonian-tech treatment pod that had been brought out of the bat cave, looking at Jason Todd lying like a corpse inside.

After a day and a night, the two barrels that were almost torn apart had "begun to take on human form", but unfortunately, the remaining essence of the pool of Lazarus in his body seemed to have been depleted.

He could no longer sustain his self-healing.

"Shall we save him with the blood of a unicorn?"

Charles said on the side:

"That's a bit of a waste, unless you're going to pull Jason into Team K as well.

This guy's combat effectiveness is very strong, he can confront Batman head-on, and if we add special equipment, we can completely make up for our shortcomings.

But it's just not easy to control.

This guy looks like a grumpy and stubborn prodigal, oh yes, boss, this thing! I found it in the ashes of Lei Xiaogu!"

The Kite Man picked up the Assassin King's Broken Cloak from the table next to him, which was also a magic item, but it was broken and required Lv3 tailoring skills to repair.

But Mason was more concerned with the few things that were wrapped in a broken cloak.

Three crystal bottles filled with green liquid, and a black quaint blade, were the weapons that Lei Xiaogu used to fight Batman that night.

Mason reached out and touched the crystal bottle, and the information label popped up:

The essence of the pool of Lazarus

Quality: Legendary crafting material

Item Utility: The pool of Lazarus of unknown origin has the power to resurrect the dead and heal all near-immortality, but its water is cursed.

When you drink it, it stimulates the shadow of the mind, and long-term consumption will change the mind, will and personality.

Maker: Three Palace Demons

Item description: If you consider the diluted blood of a Dimensional Demon God as a blessing, then you are absolutely insane.

Hint: When alchemy reaches Lv7, you can try to purify the pool water for evil power, and the purified pool water can be used as one of the important materials for the "elixir of life".

The young man glanced at the half-dead two barrels in the treatment cabin, pursed his lips, took out a bottle of pool water, put it in his bag, and reached out to touch the black, slender straight-edged sword.

The entry for this sword made Mason's eyes shine:

The head of the devil

Quality: Legendary Forging/Enchantment/Inscription Creation, Craftsmanship

Traits: Melee Blade, Curse Infiltration, Light as a Feather, Sharpened Iron as Clay, High Dark Inscription [Life Drain], High Combat Enchantment [Evil Spirit Slash]

Maker: Lars El Gul

Item description: "The Head of the Devil" describes not only the sword, but also the man who can strike fear into the hearts of the whole world when he wields it.

Note: This weapon can be further forged to improve quality and craftsmanship. But Lars El Gul is not dead, and he will come to retrieve his sword.

The young man's fingers ran across the slender, dark blade.

He waved his hand

A few moments of feeling its perfect balance and the slashing of gold and jade, especially the sword's blade, which was only two fingers wide, made Mason immediately realize its best use.

He took out his modified penguin umbrella and compared the width of the blade with the width of Maxi Zeus' lightning scepter, and was pleasantly surprised to find that the sword only needed to be slightly modified to become the last accessory of the penguin umbrella.

And the hilt of the sword, which is carved into a black demon head, is also perfect for the handle of Mason's parachute, which is much cooler than a curved umbrella handle.

Although I don't like melee combat and am not very good at melee combat, if the enemy gets close and encounters an embarrassing situation where the ammunition runs out, I will never go up and punch with my bare hands, right?

I'm not a boxer with good boxing skills!

"Then tonight's plan is to complete two barrels of life-saving medicine first, then polish my precious umbrella, and then take the time to make a bone spirit."

Mason revised his plan a little.

High-tech quasars with guns smell good.

But I really don't have time to make it tonight, and things have to be prioritized.

As he walked to his alchemy platform, he said to the kite man following behind him:

"Charles, you go back tomorrow to pack up and spend time with the children, then bring the vaccine and we'll go back to the Caribbean tomorrow night.

If Selena isn't available, forget it, it's the same for the two of us."

"Okay, Boss."

The kite man had no objection to this arrangement.

He excitedly took out his blueprint of the jetpack modification and showed it to Mason, who really turned Mason's previous suggestion into reality.

He modified the shape of his kite.

Two complete Thestrals wings were used as the main body, and the internal reinforcement was completed with special steel, forming a variable movable flying wing.

Given Charles' basic abilities as an aerodynamicist, this thing can definitely fly, but how effective it is will have to be further practiced and repeatedly modified.

Mason suggested that the kite man equip the jetpack with an emergency thruster, and the two "craftsmen" began their own production without disturbing each other.

But soon, Mason grasped the witcher pendant that trembled slightly on his chest, and he frowned and thought:

"My badge is shaking! Is there a sorceress nearby?"

At the same time, in Cooper's shop, outside the suitcase space, Dr. Hallie, yawning and about to close the shop that no one had come to all night to rest, was about to pull down the roller shutter door when he saw a beautiful black girl wearing a magician's uniform, bold fishnet stockings, and a high hat suddenly appear like magic.

She walked straight to Cooper's shop, her pretty face full of anger.

"Where's John?"

Zatanna Zatara stood outside Cooper's shop, looking at Dr. Hallie, who was wide-eyed in front of her, and the good-natured magician lady held back her anger and said:

"Let that bastard come out and see me!"

"Huh? Who is John?"

Dr. Hallie was amazed and said,

"This is Mr. Mason's shop, I'm his employee, is this lady going to come in and see our magic potion?" Today's special."

"What's so nice about these low-grade potions? There are no bright spots other than good workmanship."

Zatanna stomped her feet angrily when she heard that Zakang was not here, she glanced at the shop, and said angrily and anxiously:

"He's definitely been here! My surveillance magic has detected his tracks. But it's okay if he doesn't want to show up, anyway, it's over between me and him.

But you tell him for me that something big is about to happen, and let him get back to the mystery house as soon as possible!

I can only wait for him for half a month!"

With that, Miss Magician suddenly sniffed and sniffed as if she had smelled something strange.

The gesture caused Dr. Hallie to take a step back.

She didn't really like that

Intimate moves.

"Hmm, good luck."

Zatanna glanced at Harley with pity and whispered:

"Shadows have grown in the heart, bloodthirsty monsters trying to break free from the shackles of reason, but those who have cultivated and controlled her have gone to hell.

You've got to hurry up before you get out of control, girl.

If you drag it on, you won't be cured."

"Harley, who are you talking to?"

Poison Ivy's puzzled voice came from the basement, and just as Harley was about to answer, she saw Miss Magician disappear like a bubble in front of her.

This made Dr. Hallie blink.

She felt like something strange had happened to her again... Uh, maybe I'm hallucinating?

Never mind.

Let's drink another bottle of medicine.
