The next day, eight o'clock.

"The goddess of joy is holy and beautiful, and her brilliant light shines on the earth..."

Without drawing the curtains, Lu Ban opened his eyes to the sound of Ode to Joy.

He slept soundly that night.

That makes sense.

For an ordinary person who has a regular schedule and does not leave worries and fatigue to the next day, experiencing several hours of thrilling adventures in a foreign land can cause great damage to the body.

However, Lu Ban did not slack off and sat up directly.

As soon as he stood up, he realized something was wrong.

After stretching his body, Lu Ban felt like a new person.

He looked at his left arm, where the ratman had bitten him with his tiny teeth last night. The bandage there was now itchy, making him want to reach out and scratch it.

"Is it tetanus?"

Lu Ban curiously unwrapped the bandage, but what he saw was not rotten and mutated flesh and blood.

The wound has healed.

The wounds that were bitten by sharp teeth and overgrown with grass and trees are now basically just scabs. Those who are ruthless can just tear them off, leaving only a layer of new skin.

Lu Ban didn't feel anything wrong at all.

However, he was sure that there was nothing abnormal with his body. He did not have a physique with amazing recovery ability, and he would feel pain for a while after being hit by a punch.

In other words, Lu Ban has a big problem now.

He pondered for a while, and finally set his eyes on the quilt.

The simple and plain patterns on the quilt were rearranged to form the cold words of the system.

[Skill: Photosynthesis]

This is the skill Lu Ban acquired after completing the mission. There is nothing special about it at first glance. He was too tired last night and did not test it right away.

Now Lu Ban knows what this skill is used for.

Simply put, it is photosynthesis.

Lu Ban came to the balcony. The balcony on the 13th floor was large enough to receive the summer sun. The warm light fell on Lu Ban, making him feel extremely comfortable.

Moreover, Lu Ban could feel that energy was being produced in his body, and even if he didn't eat breakfast, his hunger was slowly disappearing.

And that wound was even more serious. After being exposed to the stronger sunlight, it began to itch. Lu Ban tore off the dead skin and scar on it, and the skin underneath had already grown back.

He looked at his arms, and there seemed to be something swimming in his blood vessels, just like the vines wriggling in the grass last night, except that these things brought Lu Ban comfort and peace of mind.

“…”

Lu Ban took out his cell phone and looked at himself in the mirror in selfie mode.

"Luckily my hair didn't turn green."

He sighed.

This photosynthesis skill allows Lu Ban to carry out photosynthesis.

As long as he is exposed to the sun, he can convert solar energy into the energy needed by his body. If Lu Ban is thrown onto a deserted island to survive, he does not need to eat any strange things and can produce and sell his own energy.

Moreover, just as plants will quickly repair themselves after being cut, the small wounds on Lu Ban's body will also heal quickly under the light.

To verify this, Lu Ban took out a kitchen knife from the kitchen, went to the balcony, and lightly scratched his left ring finger.

Blood seeped out and dripped onto the ground.

Lu Ban saw that there seemed to be something like an insect crawling out of the wound and then retracting. With the sunlight, the wound was healing at a speed visible to the naked eye.

He struck again.

After repeating this three times, Lu Ban came to the above conclusion.

“Since it’s photosynthesis, if we apply fertilizer, will it help it grow better?”

Lu Ban had the idea of ​​buying Jinkela online.

But then he thought again, the excrement after digestion is actually rich in ammonia and nitrogen. Maybe the body can regulate itself and re-absorb the nitrogen, phosphorus and potassium in these things to nourish itself.

"In the novels, those immortal cultivators who have reached a certain level of cultivation no longer need to eat or excrete. In other words, they may have mastered photosynthesis."

Lu Ban was mainly curious about the changes in himself.

"Should I be considered... a vegetable now?"

As he was muttering to himself, he heard the doorbell ring.

"who?"

Lu Ban walked to the door and looked through the peephole.

A bloodshot eye was peering at him from outside the cat's eye.

Lu Ban moved slightly away from the cat's eye.

"How strange... take another look."

He looked again and saw two policemen in uniform standing at the door.

Lu Ban hurriedly opened the door.

When the two policemen saw Lu Ban opening the door, they were about to speak when they saw the kitchen knife in Lu Ban's hand.

"Put the knife down first."

A policeman took a half step back and touched the intercom at his waist.

"Oh, sorry."

Lu Ban put the kitchen knife on the table.

"We received a call from the police saying that someone was self-harming on your balcony... Is it convenient for us to come in?"

the police comrade asked.

It seems that the neighbor opposite saw Lu Ban basking in the sun and photosynthesizing on the balcony and called the police.

"Yes, yes, please come in, please come in."

Seeing this harmonious and friendly neighborhood relationship, Lu Ban was deeply moved.

After getting permission, another policeman walked into Lu Ban's house and looked around.

"No, I just scratched my finger with a knife to see how it goes."

Lu Ban spoke the truth.

The two policemen froze in their tracks.

They looked at each other and looked at Lu Ban warily.

"This will hurt you. Do you have any request? Let me see your wound."

A policeman asked, asking Lu Ban to stretch out his hand.

Lu Ban stretched out his hands with his palms open.

The police checked carefully and found no wounds.

They looked at Lu Ban suspiciously.

At this time, one of the policemen seemed to remember something. He looked at Lu Ban carefully, checked the house number, took out the police pass to check, and then gave his companion a look.

"Since everything is fine, that's good. We'll go back first. Remember, if you have any trouble, find the police."

The two left Lu Ban's house and came to the corner instead of taking the elevator.

"What's wrong?"

The policeman who was reminded was a little confused.

"Remember the previous dangerous person report, the one linked to the hospital's psychiatric department?"

His companion took out the police bulletin and showed Lu Ban's photo and related instructions.

"…severe paranoia, persecution mania, schizophrenia, extremely dangerous!"

The two of them looked at the description above and suddenly became nervous.

"I just checked and there are no scars on his palms. He is definitely not hurting himself by holding the kitchen knife."

"Yes, and I found that his room was very clean, even under the bed was clean. Who would clean under the bed? There must be a reason for his severe mysophobia. It could be psychological trauma or he was trying to cover up something."

"The way he held the knife was very skilled, and it was in his backhand. This was not the posture for cutting vegetables, but more like an attack on someone."

"I just saw a lot of hair in his bathroom drain. Judging from the length of his hair, it doesn't look like his own, but more like a girl's."

"I always feel like there's another person in the room. I can't really explain why, it's just a simple intuition."

"There was a crowbar in the corner of the bedroom with dark red stains on it, which might be congealed blood."

The two of them chatted in low voices.

At this time, one of the policemen suddenly saw Lu Ban standing at the stairs behind his colleague.

He also held a police hat in his hand.

"You forgot your hats."

Lu Ban handed them the police hat, gave them a warm smile, and then turned and left.

“…”

The two police comrades looked at each other, their hearts filled with turmoil.
