"It's not in vain."

Zell looked at the man and the cat still in a coma, so he summoned the Poluo treasure book to check the reward.

【Mental Exchange】

It takes four points of mana to exchange the minds of the two targets.

"The four-cost spell...can't be used for the time being."

Zell sighed, and suddenly remembered that there was a six-cost card in the picture book that looked very similar to the mental exchange, and the effect was to turn one goal into another.

For example, Mao Jieka becomes Professor Feng, or in turn turns Professor Feng into Mao Jieka, but keeps his mind. That is to say, in two identical bodies, the mind is not the same. It is a one-way exchange of mind.

The reason why this card consumes more mana is that it can even copy its abilities, which is the strongest imitation technique.

If not stated explicitly, the longest duration of these spells is generally twenty-four hours, and the same is true for the summoned objects.

Next is another card.

【Blank Card】

Can be used to contain objects, and if there are already objects, they can be summoned. (The storage and summoning process does not consume mana, but cannot contain living objects, so they can be used repeatedly.)

"Is this a storage card? When will I get a savings card?"

Zell was a joke with Poluo Baodian, but the latter would not respond to him. However, Xiao Huang nodded at him as if he could understand what he was saying.

"It should be used for storage, so with this card, wouldn't it be possible to turn many things into summoning objects? For example..."

Zell looked at Hex's switcher with a dangerous look.

"If the professor wakes up and finds that the machine is gone, will he go crazy?"

After thinking for a while, he got rid of this idea, "Since there is already a mental exchange, let's just let the switch."

Looking around in the room, Zell faced the card with a bag of open cat food, and silently put it into the card.

I looked over and saw that the blank card was no longer blank, and patterns and text descriptions appeared on the card surface.

【Kaifeng cat food】

Food for cats. Raw ingredients: 33% chicken, 10% salmon, 10% beef, taurine, fructose...

"No need to be so detailed..."

Then, he turned around and pointed the card at Professor Feng's bed, and then collected it... It didn't work.

After thinking about it, he released the cat food, aimed it at the bed again, and now he put it in.

After some exploration, he almost figured out the role of the blank card.

A blank card can only hold one item at a time, and if there is an item in the card, the containment function cannot be used. However, it does not seem to have a clear limit on the size of the item, and maybe you can try to stuff a house or a cruiser in it.

Not long after Zell restored everything, he heard Professor Feng sneezing three times in a row.

He opened his eyes in a daze, saw his human hands, and immediately shouted excitedly: "I've changed back! I've changed back!"

Ahem.

The coughing sound on the side made him quickly calm down from the great joy, and he looked at Zell with embarrassment.

The students who live in the apartment have complained a lot these days. Before, Mao Jieka controlled his body and was inevitably yelling. But now if he is complained after the exchange, it is really unreasonable.

"Thank you so much! Zell. I can't imagine that if I continue like this, I will collapse!"

Feng wanted to hold Zell's hand and thanked him well, but the latter waved his hand and avoided it.

"If you want to thank me, then make me a laser pen." After that day, Zell kept thinking about the portable energy weapon in Roy's hand.

Because of the gun ban order, he could not find anything useful to protect him for the time being.

If you summon the undead when you encounter danger, you will be regarded as a necromancer.

"Laser pen? But I have already figured out what I want to give you, don't you see?"

Professor Feng obviously did not understand what Zell wanted. He thought that all he wanted was an ultraviolet flashlight for teasing cats. He felt that using such a cheap thing to repay the kindness of saving lives was too great and would be looked down upon.

"Let's take a look." After all, it was someone else's kindness, and Zell couldn't bear to refuse.

Then Feng Yidun searched and took out a design drawing from under the pillow.

It is not difficult to see from the distorted strokes that this design is from Mao Jieka's handwriting - a cat used his human body to draw a simple design picture under the wisdom of humans.

This is probably the most difficult project since Piltwolf cracked the river.

Although the drawing is very sloppy, it can still be seen that the design is a mecha.

"You want to build mechs?" Zel said in surprise.

If you ask him if he wants to turn on the mecha, he must have thought.

Don't ask, it's just that the mecha is a man's romance.

"Yes, but I can only use the remaining funds for research to help you do it. I don't know when it will be done." Feng replied.

"Do it slowly, don't worry. My request is very simple, as long as it can be used." Zell said happily. Now he knew what to do with blank cards.

"I will do my best to do it."

Feng turned to look at his converter. Zell had taken off the crystal and the damaged catalyst had completely melted, and the machine was considered broken.

Even if he took the time to repair it and found crystals as energy, he could not make the research results public.

The hard work spent over the past decade has been brought about this result.

He suddenly felt that being a cat is much happier than being a human, at least he doesn't have to worry about so many things.

However, even if he has nothing, he still has his kitten.

He hugged Mao Jieka from his seat, and he gently stroked his hair, his eyes full of regret and pampering.

Mao Jieka has been with him and works with him in this extremely small laboratory and bedroom apartment.

It always patiently listens to his colleagues talking about what outrageous things they did or said, often nodding or expressing care, just asking him not to forget to feed on time.

Feng looked at Mao Jieka and suddenly laughed: "It's not that bad, actually."

"What?" Zell didn't know what he was talking about.

"After this incident, I understood Maujeka, and I felt like my cat and I became closer."

"Is that right? It's awake." Zell pointed to the white cat in Feng's arms. It slowly opened its eyes and narrowed into a slit of pupils that it was reusing the cat's eyes to light.

"Oh, my kitten." To prove that their relationship has become better, Feng buried his face directly in Mao Jieka's arms, and then kissed and hugged him.

"Aowoo!"

As soon as Mao Jieka woke up, he saw the perverted man marching his chest. He subconsciously used his shadowless foot and scratched his bloody marks mercilessly before entering the bed. He did not forget to look back and licked the messed hair with disgust.

"This smelly cat!" Feng Yi was in a mess, and he didn't expect the slap in the face to come so quickly.

"Don't take it to heart. Cats are just like this. They are not well-equipped." Zell smiled and touched Xiao Huang. The latter was very willing to lift Xiao Jio and hug his fingers.
