Mason had been running around all this time, but the Poison Ivy Girl who stayed in Cooper's hut didn't waste any time.

She didn't just learn alchemy with Mason for fun.

She didn't want to turn back into the manic madwoman she used to be, and if she wanted to control her emotions in her own hands, she had to learn how to make those three potions.

Thanks to day and night practice and Poison Ivy's powerful manipulation of plants, it's finally time to bear fruit.

With Mason watching, Ivy spent thirty minutes selecting the ingredients to complete a tranquilizer, the easiest of the three mood-related potions.

But she didn't have the help of Mason's manufacturing system, which was entirely based on her own practice.

Ivy extinguished the flames of the cauldron, filled the potion into the crystal bottle with an alchemy spoon, and handed it to Mason with both hands, the look on her green face was as worried as if she were a student handing in her homework for the teacher's review.

Harley Quinn, who was watching from the sidelines, also covered her mouth and stared at Mason with wide eyes waiting for his judgment.

She has been with Ivy these days, she knows how hard her best friend has worked, although she is about to go crazy, she still hopes that her good friend can get a "high score" in this "practical assessment".

"The color is right, and the taste is fine."

Mason sat in his chair and put the medicine that Ivy handed over in front of his eyes, and after a few seconds, he shook the bottle in his hand and said to Poison Ivy:

"But the lack of careful filtration allowed it to precipitate, which could affect the final effect of the tranquilizer. But for newbies, it's good to be able to do that.

Next up is the last item, Ivy.

You know, as alchemists, we should have enough confidence in our craft, and if you fully understand the mystery of this recipe, then you should know the effects of this potion.

So..."

Mason handed the potion back to Poison Ivy and said:

"Drink it."

"It's not fair!"

Harley Quinn, who was watching, shook her double ponytail blonde hair and shouted:

"I haven't seen you drink the potion yourself, Mason, I think you're embarrassing Ivy."

"An alchemist who doesn't even dare to drink the potions he makes himself can't be called a potion maker."

Mason emphasized:

"And I have to drink a bottle of 'Brown *** Eagle' every morning to keep the day energized, which is not a double standard. How can you dare to drink something that you don't dare to drink to your companions?"

"Crooked!"

Hallie snorted and said:

"I also know that you asked the Kite Man to secretly recruit long-term drug testers in the Minions Guild in Gotham, which I joined the other day!

I also saw the information posted by the kite people!

Hey, I'll drink!"

She snatched the potion from Mason's hand, raised her head and poured a bottle of potion before Poison Ivy could stop her, and after drinking it, she frowned and pursed her lips, as if she was savoring the taste of the potion.

"Well, it doesn't smell right."

Hallie blinked and said: ....

"Why is it so bitter? Mason's tranquilizer tastes great orange, you don't have that, Ivy, are you mistaken?"

"Because taste is also a very important part of the potion effect."

Mason picked up his watch and read the seconds, explaining to Harley Quinn:

"In order to take care of your feelings, I specially added concentrated orange juice to your potion, I know you like this fruit..."

"Puff"

Before he could finish his sentence, Harley Quinn fell headlong to the ground, lying on the ground in a very indecent posture and snoring soon with her ass facing the sky.

Mason glanced at the time and said:

"Thirteen seconds from the time you drank it to the time you fell asleep, it looks like your potion

It works well.

I really admired Hallie's appetite for a small bottle in one go, she had drunk it so many times, didn't she know that the normal dosage of this thing was calculated according to 'drops'?

The one she had just drunk was enough for her to sleep for three days.

But that's not a bad thing, she's been a little too emotionally released lately, and she really needs to recuperate for a few days."

"Did I pass the test?"

Poison Ivy waved her hand, and the branches of a potted plant at the table behind her quickly grew like a living vine, rolling Harley Quinn up from the ground and quickly "weaving" it under her into a rattan bed to make her sleep more comfortable.

Ivy looked up at Mason, the evil alchemist nodded, and said:

"You can start trying to make Eliminators, the Palliative is the most troublesome part of the process, so save it for the end. But now that you're getting started, there's something to tell you.

I need your ability to manipulate plants, Ivy.

To be precise, it's my small organization that needs your help, and you can interpret this as an invitation. I'll tell you about the details of the work when we get to our destination.

If you don't have a date tonight, let's go now?"

"Hallie kept telling me that you must be from a secret organization, and she was pretending to be trying to find out your little secret, and it seems that she guessed it right.

She's really sensitive in that regard."

Poison Ivy didn't have much of a shock.

She has been "famous for a long time" in Gotham, and she has been a first-line villain for several years, so she has long been well-informed. In the face of Mason's invitation, she behaved very calmly.

But before leaving, she glanced at Harley Quinn, who was sleeping on the rattan bed, and said:

"Is it okay to leave her here alone?"

"Let her rest."

Mason took out the cloak and put it over Harley to keep her from catching a cold, and took out a black, briefcase-sized drone from his pocket and placed it on the table.

The moment the finger is disengaged, the thing activates.

Six X-shaped wings popped out of its rear and began to patrol the basement area.

After leaving the basement, Mason unleashed the remaining three identical drones, put them on guard in Cooper's shop, and placed his own bottles and cans behind the counter, which was considered to be the end of the defense.

He turned his head to see Poison Ivy looking at the drones with a curious gaze, and explained: ....

"It's called 'Pterodactyl,' a civilian armed drone made of futuristic technology, very intelligent and able to scan all life that comes close to it, and will trigger an attack program if it is not authorized to enter.

Generally speaking, a short frequency high voltage*** is enough to protect Hallie and deal with thieves."

"But there's more to Gotham than thieves."

Poison ivy sat in the body of Mason's scooter, put on her green helmet and said with some concern:

"The city is full of crazy people in fanatic costumes."

"That's why I gave them a second level of authorization."

Mason shrugged his shoulders and said:

"*** When it's useless, it will activate a quadruple small-caliber riot gun and a special paralyzing bullet, plus the lethal current attack released when attacked, it should always reassure you, right?

If these are not enough, then they will self-destruct in place when destroyed.

The power is equivalent to the impact of three high-explosive grenades exploding at the same time. Uh, if you're not at ease, I can put a 'Griffin, a military assault drone.'

Its firepower is battlefield level—"

"Enough is enough."

The Poison Ivy Woman waved her hand and said:

"Where did you get all that crazy sounding stuff?"

"Didn't I say that before? I went out and found some great friends."

Mason grinned and said:

"She's given it all

My samples, when I have free hands, can make these pieces of equipment on a large scale, and when the time comes to equip them with my homemade engineering bombs, they will all turn into cuties that can make enemies cry and cry.

Sit tight.

We're leaving."

The young man twisted the handlebars and let the scooter swoop into the air with a catapult start in place.

He wants to take Poison Ivy to Harbor Miller, cross the World Gate there, go to the Forbidden Forest, complete the harvest of the potions field, and invite Poison Ivy to be the "gardener" of Team K.

As long as this sister's ability to manipulate plants is used well, Mason will not have to have a headache for the lack of alchemy materials in the future.

But tonight at Cooper's shop is not destined to be quiet.

Ten minutes after Mason and Poison Ivy left, the sound of motorcycles from far and near sounded in the gloomy night of Crime Alley, and a batmobile sped towards and stopped in the alley opposite Cooper's shop with a dashing turn and graceful precision.

Then, a short figure jumped out of the motorcycle.

He wears a black cloak, a very professional ninja bodysuit, and a domino mask found in the Batcave on his face, covering his eyes and protecting them with white goggles.

The guy looked left and right vigilantly, then took a katana from his motorcycle and put it behind him, taking out a lot of bits and pieces of throwing knives and claws and loading them into his body.

When everything was ready, he grabbed an assembled firearm and pulled the trigger on Cooper's shop, swishing three smoke grenades into it, making the shop more than enough for his next armed raid.

For Damian Wayne's short life, it was definitely a shame to be defeated by Mason and Catwoman in the Gotham incident half a month ago.

He originally thought that he would have to compete with Batman, but he didn't expect that he hadn't even fought the janitor. ….

This makes Damian, who thinks highly of himself, very uncomfortable, and he sneaked out of Wayne Manor tonight not to seek revenge, but just to fight Mason Cooper again, so as to prove that his defeat last time was purely due to Mason's "shameless sneak attack".

It sounds like a kid who doesn't admit defeat.

But considering that Damian's actual age is only eleven years old, it does make sense.

He took advantage of the smoke bomb to take effect, jumped through the window and jumped into the Cooper shop on the second floor, and was about to attack Mason, but he rolled violently when he hit the ground.

Accurately dodged the high-voltage current coming from behind.

There was a grandfather of the King of Assassins, Jean Damian's basic skills were very solid, and he didn't stop after dodging the first round of attacks, jumping in the smoke several times in a row to make himself lie on the dead end of the second floor of the house.

He looked towards the sneak attacker.

A strange-looking drone was then seen hovering in the smoke, which made Damian frown.

"Who would be a serious person to install this kind of expensive and advanced drone in their own home?"

The genuine young master of the Wayne family complained in his heart:

"This Mason Cooper is really not a serious person! There must be a lot of secrets in this house."

As he thought, he threw a dart at the black drone, which slammed into the drone's shell and then a blinding electric current sprang up.

Micro EMP SHOCK!

The Wayne family never lacks this kind of gadget.

Damien thought that such an attack would disable the drone, but he did not expect that the drone not only withstood the attack of the EMP, but also reacted quickly to re-lock the target.

This time, it was not a warning ***, the black shell bounced outward, and the quadruple small-caliber riot gun that occupied two-thirds of its body was revealed.

In an instant, a shuttle of bullets swept over, and the accuracy was terrifying.

Caught off guard, the rice rolled over and landed lightly on the floor of the first floor from the second floor, and with a swoop, he pulled out the katana behind his back and was ready to cut down the unscrupulous drone.

But when I turned around, I saw the other three identical intelligent people

The machine came up from all sides.

At first, it was discovered that Rice's drone shared target data and threat levels with them, and these gadgets were not polite, but in the blink of an eye, Mason's small shop was thrown into a mess by bullets flying everywhere.

To say that Damian Wayne is really powerful.

Inheriting the excellent bloodline of the Wayne family and the King of Assassins family, he did not panic at this critical moment, and the blade in his hand was swung to match the bulletproof cloak behind him, and after several rolls, he approached one of them.

These little creatures are very fast and extremely nimble, moving at high speed in tight spaces without hitting obstacles, but they are clearly not fast enough to react quickly enough to an eleven-year-old Master Assassin.

At the moment when the knife light was on, the drone in front of him was split into four.

But before Rice could catch his breath, an extreme sense of threat rose from his heart and rushed straight into his head, making him flip his cloak and throw himself backwards.

With a loud bang, the severed drone blew itself up in a narrow place, shattering all the bottles and cans in the entire hut while pushing the rice headlong into the wall. ….

It makes the young man dizzy for a while.

Then he saw that the remaining three drones were lining up in a "hunting" formation in the smoke and swooping down on him.

Rice was also ruthless, scolding Gotham in his heart for being a ghost place, and even a 17-year-old could assemble this kind of killing machine that was much more advanced than a bat drone.

But with the first experience, it was much easier to deal with the remaining three "Pterodactyls".

It took him two or three minutes to finish off these troublesome guys, and four explosions in a row turned Mason's shop into a garbage heap, and the stairs between the first and second floors were *** shattered.

Although the rice that had been blown up four times unprepared was not injured, the breath in his heart not only did not come out, but he became more and more angry, and he deeply felt that he had made the mistake of underestimating the enemy again.

If I knew that Mason was so difficult, I should have done a good job of reconnaissance in advance before coming over.

However, it was a bit embarrassing to leave like this, so Rice decided to continue the infiltration, but he didn't notice that one of the magic bottles that Mason had placed on the counter in the explosion had been affected and smashed to the ground.

There was a crisp click, and then in a low roar, the zombie king Jin and shining appeared!

The horrible creature screamed and waved its claws at the rice, and the eyes of the zombie king were red with the stimulation of fresh flesh, and the sudden appearance of this big man startled Damian.

But he was also prepared, and he was not afraid to rush forward with a long knife.

Five minutes later, his clothes were shattered to smithereens, and the katana in his hand was broken, and Damien, who was in a state of embarrassment, looked viciously at the zombie king behind him who was suppressed in the ruins by him with the secret technique of the Assassin Alliance, and he felt that his bones were about to be broken by the rough-skinned bastard.

"You've won this time, Mason Cooper!"

Rice wiped the blood from the corner of his mouth, staggered with the blown katana and opened the door to leave, and said cruelly:

"I'll give you a good look next time!"

Maybe it's a mess of houses that hides the breath, or maybe it's just a "self-explosion war" that has made rice, which has not yet reached the peak of penance, relax its vigilance.

In short, Damian didn't notice a rickety figure behind him coming out of the basement with a baseball bat.

"What the hell is this?"

Harley Quinn, who had drunk an entire bottle of tranquilizer and fell asleep, had to be woken up by an explosion close to her before she could sleep.

But at this time, the drug was still kicking in, and she was half-clad in an invisibility cloak like sleepwalking, dragging a baseball bat to open the basement door, yawning and looking out.

Then, at a glance, Harley saw a sneaky short thief picking the door with a knife!

No!

No, how did he pry it out from the inside?

Hey, no matter!

The damn thief actually dared to come to Mei

Forest's shop is wild?

Harley yawned, put on her invisibility cloak, and grabbed the baseball bat with both hands to get closer to Damian, who was whispering.

As the young man was about to leave the place he had destroyed, there was a loud thud, and Harley's baseball bat smashed firmly on the back of his head.

"Hell! It's been shaded!"

It was Damian Wayne's last thought before he stumbled into a coma:

"Mason Cooper! You wicked bastard, I don't share it with you!"
