Ultimate Supreme Soldier King

"Remember, no matter how painful it is, you must stay awake!" Catherine said seriously.

"What if I passed out?" Su Chen asked.

"You'll become retarded!"

"Uh..."

Su Chen extended his arm, and Catherine personally gave him the injection.

"Kate, you're not tricking me, are you? Why don't I feel any pain at all?" Su Chen wondered.

The anticipated pain did not occur.

"The effects of the medicine will take a while to kick in," Catherine explained.

Su Chen seemed to have guessed how Catherine was going to help him.

About five minutes passed, and Su Chen finally reacted.

But it wasn't pain.

He felt that after the Shura Potion entered his body, it was drawn by a mysterious force towards his heart.

And then...

It disappeared!

Gone!

Damn it.

Could the Shura Potion have expired?

No, it hadn't disappeared!

Su Chen discovered that though the Shura Potion had vanished, a mysterious energy had emerged within his heart.

As soon as the mysterious energy appeared, his heartbeat began to accelerate drastically.

The speed was simply inconceivable.

It felt like stepping on the accelerator of a sports car.

Generally, the stronger the body's physical condition, the slower the heartbeat.

For example, an average adult's heart rate is about sixty to eighty beats per minute.

For those who exercise regularly, or athletes,

their heart rate would be lower than sixty beats per minute.

An athlete's slow heartbeat is due to a strong heart—each beat is equivalent to an ordinary person's one and a half beats.

Under normal circumstances, a slower heartbeat indicates a stronger cardiac function.

Of course, athletes have a slower normal heart rate, but their maximum heart rate is faster than that of ordinary people.

The maximum heart rate for ordinary people is 220 beats per minute.

Even athletes absolutely cannot exceed 220 beats per minute.

Once surpassing this speed, a person will die from burst blood vessels.

But a Martial Artist's maximum heart rate exceeds 220 beats per minute.

The stronger they are, the higher the limit of their heartbeat speed.

A heart rate surpassing 220 beats signifies surpassing human limits and stepping into the Mortal Realm.

Each increase in minor realms adds 20 beats to the heart rate limit.

Ascending a major realm adds 100 beats.

For instance, Catherine of the Basic Extraordinary Realm now has an extreme heart rate of 320 beats per minute.

Before using the Shura Potion, Su Chen's heart rate was already very slow, less than thirty beats per minute.

But after using the Shura Potion, his heartbeat began to speed up uncontrollably.

Thirty-five beats per minute.

Forty beats per minute.

...

One hundred beats per minute!

And it continued to climb.

"An accelerated heart rate is normal. Ordinary people's limit is 220 beats. Using the Shura Potion will break your human limit and elevate your heart rate to between 220 and 240 beats," Catherine explained.

Sure enough, Su Chen's heart rate continued to soar until it quickly reached 220!

Then, it stopped at 220, seeming to want to surpass it, but unable to.

"Ah, it hurts so much!" When his heartbeat reached the limit of an ordinary person, Su Chen finally felt the pain.

"Hang on, you must not pass out! Even if your heart rate exceeds 220 just once, it means you've succeeded!" Catherine said with a serious expression.

However, Su Chen's heartbeat remained at 220 beats per minute.

Just couldn't surpass 220!

At the same time, the pain Su Chen felt became more and more intense.

His body began to tremble.

Catherine was a bit anxious.

Because Su Chen's heart rate just couldn't exceed 220.

220 is the maximum heart rate for ordinary people.

Reaching this speed imposes a great load on the human body.

If sustained for too long, the person would die of heart failure.

It had now been five minutes.

If Su Chen's heart rate didn't exceed 220 within ten minutes, it would mean that using the Shura Potion had failed.

And the only outcome of failing to use the Shura Potion is death!

"Come on! You can do it!" Catherine silently cheered for Su Chen in her heart.

Now, she couldn't help Su Chen anymore.

Everything depended on Su Chen's fate.

Seven minutes.

Eight minutes.

Nine minutes!

Only one minute was left.

Catherine was on edge.

If after this minute Su Chen's heart rate still couldn't exceed 220,

It would mean that Su Chen's use of the Shura Potion had failed!

Su Chen... would die!

Nine minutes and fifty seconds.

Nine minutes and fifty-one seconds.

...

Nine minutes and fifty-five seconds.

Catherine was in despair.

The heart rate monitor showed that Su Chen's heart rate was still 220 beats per minute.

Only a few seconds were left.

Unless a miracle happened.

Nine minutes and fifty-nine seconds.

Ten minutes!

Finally, Su Chen's heartbeat was no longer 220 beats per minute.

Instead...

It suddenly dropped to zero!

Looking at the unresponsive heart rate monitor, Catherine was completely frozen.

Failed.

Although she had known that using the Shura Potion had a ten percent fatality rate,

when the moment actually arrived,

Catherine still found it hard to accept.

Was this man, truly dead?

"Kate, if you're bored you can come play with me, I'm bored alone anyway."

"Kate, what are you doing in my room so late? Missing me?"

"I'm just telling you, not asking for your permission."

"Kate, if I died, would you really not feel sad for me?"

...

One scene after another of Su Chen's arrival at the manor replayed in Catherine's mind.
