13 Can't Use Your Potential Whenever You Feel Like It

"I'm sorry, I always carry a lot of it. I might not have noticed this. I still have some in my pocket. You can take it yourself..."

Lin Feng didn't pay attention to Zhang Tong's words. His attention was focused on his own potential. He still didn't know much about this ability, so he would try again whenever an opportunity arises.

Staring at the bag of potato chips, he began to warm up the same feeling he had during the day, and imagined his target.

Soon, a miracle happened!

The daily production barcode on the bag of potato chips began to change!

It was a short moment that was hard to catch with the naked eye! The production date changed to last week's September 18th!

"My god! This potential is amazing!" Lin Feng's heart was beating wildly, and he was extremely excited!

However, just as he was about to tear open the packaging to fill his stomach, he felt his heart still beating wildly!

He was clearly not that excited anymore. Why was this happening?

Before he could get an answer, he felt dizzy!

He shook his head. Not only did the feeling not weaken, it worsened!

After walking for only five or six steps, he could no longer control his body! His vision blurred. He fell heavily to the ground and fainted!

"Eh? Buddy! Lin Feng, what's wrong?" Zhang Tong, who was still carrying Yinyang on his back, immediately turned and shouted at Lin Feng. Then, he put down Yinyang and rushed over to check Lin Feng's breathing and other vital signs.

"Phew... thank god!" Zhang Tong seemed to know some medical knowledge. After confirming that Lin Feng was only in a normal coma, he heaved a sigh of relief.

Then, he said with a bitter face, "What day is it today? ! One was injured and the other fainted! And you want me to think of a solution all by myself? Is God giving me a chance to lose weight? !"

Now that there was no one around, he was not the only one who could take care of the two injured people!

After letting out a heavy sigh, he could only grab Lin Feng and carry him by his waist. Yinyang also tactfully came over to help.

Just like that, the three of them staggered towards their own dormitory building.

"Hiss... What's wrong with me..." When he woke up again, Lin Feng's head was still very dizzy. He rubbed his head and looked up at the clock on the wall. It was already 11:40 pm.

"You're awake? What happened just now?" Yinyang sounded concerned and handed him a cup of drink.

Perhaps it was because of the duel with Maki Jiro, his trust in Lin Feng had increased a lot. Ever since Zhang Tong sent Lin Feng back, he had been waiting by the side.

"Thank you..."Lin Feng took the drink and took a sip. He felt much better. He didn't forget the situation just now, but he didn't know why he suddenly fainted. He only remembered that his heart was beating wildly before he suddenly lost consciousness.

"What's wrong? Do you need to go to the infirmary again?" Yinyang pulled a chair over. The injury on his ribs made his sitting posture very unnatural.

"It's nothing. I'm probably too tired." Lin Feng himself didn't have an answer.

But Yinyang frowned and said, "Are you using [ potential ] too frequently?"

These words reminded Lin Feng. He clearly remembered that he only fainted after using potential for the second time.

"Is there a limit to the use of potential ?" Lin Feng's question triggered Yinyang. He said unhappily, "You really don't know anything." He explained, "No matter what potential you have, there is a limit to the use of it. It either consumes aura, physical strength, or bear other costs. It will cause great burden to the body if you use it too frequently! You must have used it too much in the duel with Maki Jiro, so you fainted. If nothing goes wrong, you are depleting your own spiritual energy!"

"I see..." Lin Feng nodded and firmly remembered this rule.

Thinking of the incident where he fell asleep in front of the infirmary after using it once, and the consequences of using it a second time, he vaguely guessed something.

"If that's the case, the price of overusing my potential is that I will faint? Was it due to my spiritual power?" He muttered. He subconsciously touched the items around him, hoping to find the bag of potato chips as he didn't want to expose his potential .

But he still couldn't find it.

"Knock, knock, knock!" There was a knock on their dormitory door.

"The door is open!" Yinyang shouted. A chubby figure pushed the door open and walked in.

Zhang Tong, who was wearing slippers, smiled and threw two bags of chips to Lin Feng, saying, "Here are your chips!"

He picked up the bag and saw that it was the bag of chips that was produced on September 18th!

He looked at Zhang Tong, who was smiling at him in horror, and thought, "Has my secret been discovered?"

"Hehe..." Zhang Tong laughed, "I have a lot of snacks. If you want to eat them, you can ask me. You don't have to lie to me about the production date!"

Realizing that his friend did not guess his potential correctly, Lin Feng heaved a sigh of relief. He laughed dryly and said, "Eh... you are really generous and smart. Nothing can be hidden from you..."

Zhang Tong flicked his hair and said proudly, "Of course! In our town, I'm famous for being a smart kid!"

The three of them were all cheerful people. After a few words, they began to talk and were barely friends.

In his joy, Zhang Tong decided to show off his skills!

After taking out the steak from the refrigerator, he started to cook in the kitchen of the dormitory. Yinyang also helped him.

Lin Feng was still lying on the bed, thinking about his potential.

He had used it twice today. One time, he had modified the level of beginner breathing technique, and the other time, he had modified the production date of the potato chips and passed out.

In other words, this was the upper limit of his usage, but he did not know the rules for using it.

Simply put, how long would he have to wait to use it once.

"Yinyang! I can only use my potential once?" He had already treated Yinyang as his encyclopedia.

After opening a bottle of milk, Yinyang replied loudly, "That's not certain! If you pay the price with your spiritual power, you will pass out naturally after exhausting it. As long as you train your spiritual power properly, you can increase the number of times you use it!"

In other words, the next time you use your potential, you must use it when your spirit is full! That way, you won't pass out!"

Lin Feng felt that his buddy's reminder was extremely important. If he used it frequently during non life and death situations in a battle, he would be sending himself to the grave!

After all, no enemy would have a hard time over an opponent who had passed out!

Here comes the problem!

If his spiritual power will determine the number of times a potential is used, how should he increase spiritual power?
