Chu Chen's heart was as anxious as fire, and he used his body technique, like a red light, and came to the residence of the second senior brother Zhu Wuneng at a very fast speed.

"Bang!"

As soon as he arrived at the second senior brother's residence, he heard an explosion inside, followed by black smoke, and it was obvious that the scene of the fire was clear.

Before Chu Chen could enter, Zhu Wuneng came out of it with a disgraced face, his fat body was covered with soot, and when he saw Chu Chen, he couldn't help but be stunned for a moment,

"Little junior brother, why are you here? Zhu Wuneng was slightly embarrassed.

"Senior brother, you are ......"

Chu Chen didn't answer him, but pointed curiously at the billowing black smoke coming out of his courtyard.

"The alchemy just now, I didn't control it well, and it turned out to be fried. Zhu Wuneng said with a blushing face.

After all, he is good at alchemy, and now he has made a mistake in the field he is best at, and he has exploded.

The fryer is the most serious mistake in alchemy, and compared to it, the waste pill is simply not a problem.

Chu Chen nodded as if he didn't understand, after all, he didn't understand alchemy, nor did he understand what a fryer was, let alone how embarrassing a fryer was.

"Senior brother, I have something I want to ask you. ”

He changed the topic and asked, "I want to ask, after taking the pill, the effect is very good at first, but after taking too much, the effect is poor, what is the reason?"

"That's what you say. ”

Zhu Wuneng patted the dust on his body, the fat on his body continued to sway with his movements, and after tidying up for a while, he said, "Actually, this is normal. ”

"Normal?"

After Chu Chen heard this, he was quite puzzled.

"This phenomenon is called drug resistance. Zhu Wuneng explained: "You think, the more pills you take, the greater the resistance produced by the body, and the effect will naturally get worse and worse." ”

This sentence was like a slap in the face, which made Chu Chen wake up on the spot.

He thought of an example from Earth.

Among the antibiotics, there is a drug called penicillin.

The main function of penicillin is to eliminate bacteria, which can relieve diarrhea or headache and fever.

There is a person who loves cleanliness, when he goes to the canteen to eat, he always feels that the food in the canteen is not clean, and after eating, he takes a pill of penicillin and eats it for two consecutive years.

Eventually, I caught a cold, and then I couldn't take any medicine, and I finally died.

Well, a cold sick person died.

Because long-term use of penicillin causes bacteria in the body to produce antibodies.

After the bacteria in the body are killed by penicillin, they will be reborn again, and the reborn bacteria will develop some resistance, this person has been taking it for two years, and the bacteria in the body do not know how much they have been updated, and the latest generation of bacteria has been invulnerable.

So, a cold can kill him.

Having said that, the elixir on the Martial God Continent is also a medicine.

Although it is a positive side, there is always a similar ingredient in it, and it has a hundredfold system blessing itself.

Taking one pill is equivalent to taking one hundred pills at the same time, and the body will definitely develop resistance.

Therefore, the effect of this elixir on oneself is getting smaller and smaller.

I see!

After thinking about it, Chu Chen suddenly breathed a sigh of relief, and his heart was a lot more steady.

His hundredfold cultivation system is still useful, but his body has developed strong drug resistance, and the second-grade high-grade pill is no longer useful.

If you want to improve your cultivation, you can only take the third-grade lower-grade pills.

"Thank you, Senior Brother, for your doubts. ”

Chu Chen happily hugged his fists and saluted the second senior brother.

This joy, the aura on his body accidentally leaked a little, which immediately made the keen Zhu Wuneng perceive it.

"You...... Progression to ...... Eight-star ...... Eight-star ...... Eight-star martial artist?"

He couldn't believe it, looking at Chu Chen, he couldn't speak.

"Oops!"

Chu Chen's heart froze, he leaked his breath carelessly, showing his strength.

You know, yesterday he was still a five-star martial artist, and after only one day, he advanced to an eight-star martial artist, which is simply too fast!

In the past, in Qingyang County, due to the small place, people didn't know much, and their horizons were narrow, so naturally there was no problem, even if they found a problem, but because of their strong strength, they didn't dare to say anything.

But now it's the Nine Spirits, and the masters in it are like clouds, everyone has seen the world, and it's hard to deceive them.

How is it possible to advance to three stars overnight?

If this news spreads, others will definitely see him as a monster.

Just when Chu Chen wanted to break his head and couldn't come up with a reason, the second senior brother Zhu Wuneng spoke.

"Did you take the Barrier Breaking Pill?"

This is also what he tried to ask, after all, he was promoted to three levels in a day, and only the Barrier Breaking Pill could do it.

The barrier-breaking pill is a four-grade high-grade pill.

Below the realm of the Great Martial Master, taking this Pill can immediately advance once, up to three times, and you cannot use the Barrier Breaking Pill to break through the Nine-Star Martial Master and advance to the realm of the Great Martial Master.

However, this four-star high-grade elixir is very precious, although it is not of the slightest use to the Martial King realm, but the wealthy families or sect disciples also like to use it to break through quickly, which can save a lot of time.

Therefore, the price of the barrier breaking pill is also very expensive, and it usually costs 5,000 lower-grade spirit stones to be able to buy one.

Three pills are fifteen thousand lower-grade spirit stones!

"It's true that I've taken the Barrier Breaking Pill. ”

Chu Chen was worried that he couldn't find a reason, so he took over the second senior brother's words.

"That's right. ”

Zhu Wuneng looked like a matter of course, and then said earnestly: "Little junior brother, although the pill is helpful for the improvement of cultivation, but you listen to what Senior Brother said, the pill is only an auxiliary, and the most important thing is your own cultivation!"

"Why?"

Chu Chen asked very puzzled.

Zhu Wuneng smiled bitterly and said: "Second Senior Brother, I am nineteen years old this year, and I have excellent talents, how can I be the same as the fourth child at this age to reach the three-star Martial King, but because I have relied on the pills I have refined for a long time, I can only reach the two-star Martial King now!"

"How so!"

Chu Chen didn't understand very much, the pill could assist in cultivation, and he should cultivate faster and faster, how could he take the pill the more slowly he cultivated?

"While taking the pill, although I have improved my cultivation, the aura in my body has become more and more vain. Zhu Wuneng said very sadly: "The aura is vain, which will lead to a tenfold increase in the difficulty of advancing in the future! Now we are only in the low-level realm, this side effect is not obvious, and when we reach the Martial Emperor, it will be prominent." ”

Zhu Wuneng was in a very dull mood, and then said: "This is also the reason why the Martial Sect realm above the Martial Emperor is so rare. ”

Pills still have such side effects??

After Chu Chen heard this, his heart suddenly cooled.

I have a hundredfold cultivation system, I have taken a lot of pills, and then multiply it by a hundredfold, isn't this taking countless pills?
