"Remember, no matter how much it hurts, always stay awake!" Caterina said with a serious expression.

"What if I faint?" Su Chen asked.

"It's going to get mentally retarded!"

"Forehead ......"

Su Chen stretched out his arm, and Katerina injected him herself.

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

The expected pain did not appear at all.

"It won't take a while for the effects to work." Katerina explained.

Su Chen nodded, looked at Caterina with a wicked smile on his face, and said, "Cortana, what you just said, you will help me, how do you help me?" ”

Caterina's cheeks were slightly red, and she turned her head away from Su Chen, "You'll know when the time comes." ”

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

After about five minutes, Su Chen finally reacted.

However, it is not painful.

He felt that after the Shura potion entered his body, it was actually pulled by a mysterious force and converged towards his heart.

And then......

It's gone!

Gone!

Meow that Mi's.

Could it be that this Shura Elixir has expired?

No, it didn't disappear!

Su Chen found that although the Shura Elixir had disappeared, a mysterious energy had appeared in his heart.

When that mysterious energy appeared, his heartbeat suddenly began to accelerate.

It's unbelievably fast.

It's like stepping on the accelerator of a sports car.

In general, the more physically fit a person is, the slower the heart rate.

It's like the average adult's heart rate, which is about 60 to 80 beats per minute.

And regular exercise, or athletes.

The heart rate will be less than 60 beats per minute.

The athlete's heart rate is slow because the heart is strong, and one beat can be equivalent to an ordinary person's one point and five times.

Normally, the slower the heartbeat, the more powerful the heart.

Of course, an athlete's normal heart rate will be slower, but its extreme heart rate is faster than the average person's.

The average person's heartbeat is at a limit of 220 beats per minute.

Even for athletes, it is absolutely impossible for the heart to beat more than 220 beats per minute.

Once this speed is exceeded, the person's blood vessels will burst and die.

And the extreme heartbeat of the warrior exceeded 220 beats per minute.

The stronger the strength, the higher the limit jump speed.

The fastest heartbeat exceeds 220 beats, which means breaking the limits of the human body and entering the mortal realm.

For each small level increase, the limit heart rate increases by 20 beats.

Raise a large level and increase your heart rate by 100 beats.

For example, Katerina, who is at the beginning of the Transcendent Realm, now has a maximum heart rate of 320 beats per minute.

Before Su Chen used the Shura Elixir, his heart rate was already very slow, with a frequency of less than thirty beats per minute.

But after using the Shura potion, his heartbeat began to accelerate involuntarily.

Thirty-five times per minute.

Forty beatings per minute.

……

One hundred times per minute!

It's still improving.

"It is normal for the heart to beat faster, the limit heart rate of ordinary people is 220 times, and using Shura Elixir will allow you to break the limit of the human body and increase your heartbeat to between 220 and 240 times." Katerina explained.

Su Chen's heartbeat really continued to rise, and soon it increased to 220 times!

Then, it stopped at 220 times, as if it wanted to surpass, but it never became.

"Ah, I hurt so much!" When his heartbeat reached the limit of ordinary people, Su Chen finally felt the pain.

"Hold on, don't pass out! Just make your heart beat 220 beats, even if it's just one more, and you've succeeded! Caterina said with a serious expression.

However, Su Chen's heartbeat has been maintained at 220 beats per minute.

You just can't go over 220 times!

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

The body began to tremble.

Katerina knew it was time.

She took out a VR glasses and put them on Su Chen's head.

When he saw the content in the VR glasses, Su Chen was stunned.

Unexpectedly, there were scenes of content not suitable for children to watch in the VR glasses!

"Damn, I didn't expect Cortana to have this thing!" Su Chen admired while watching.

is also a Dongyin movie, wearing VR glasses, and watching without VR, that is a completely different concept.

It feels so real.

It's exactly like the real thing.

It turned out that Katerina wanted to distract Su Chen in this way.

In fact, Su Chen also often uses this method.

The results are simply surprisingly good.

And with this method, it is more conducive to Su Chen's heartbeat to break the barrier of 220 times.

Minutes and seconds passed.

Katerina was a little anxious.

Because, Su Chen's heartbeat just can't exceed 220 times.

220 is the limit speed of an ordinary person's heartbeat.

Reaching this speed will put a great strain on the human body.

If this state is maintained for a long time, then the person will die due to heart failure.

It's been five minutes now.

If within ten minutes, Su Chen's heartbeat exceeded 220 times, then it meant that Su Chen failed to use the Shura Elixir.

There is only one result of failing to use Shura Elixir, and that is death!

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

Now, she can't help Su Chen either.

Everything can only depend on Su Chen's creation.

Seven minutes.

Eight minutes.

Nine minutes!

There is only one minute left.

Caterina's heart was in her throat.

If this minute passed, Su Chen's heartbeat would not be able to exceed 220 times.

That means that Su Chen's use of the Shura potion failed!

Su Chen...... Will die!

Nine minutes and fifty seconds.

Nine minutes and fifty-one seconds.

……

Nine minutes and fifty-five seconds.

Katerina was desperate.

The heartbeat detector shows that Su Chen's heartbeat rate is still 220 beats per minute.

There are only a few seconds left.

Unless a miracle happens.

Nine minutes and fifty-nine seconds.

Ten minutes!

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

But......

Suddenly zero!

Looking at the unresponsive heartbeat tester, Caterina froze.

Failed.

Although, she has long known that the use of Shura potions has a ten-percent lethal rate.

But when the moment does come.

Katerina still had a hard time accepting it.

Is this man really dead like this?

"Cortana, if you're bored, you can come and play with me, I'm bored by myself anyway."

"Cortana, what are you doing in my room so late? Missed me? ”

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

"Cortana, if I die, won't you really grieve for me?"

……

What happened when Su Chen came to the manor came to Caterina's mind one by one.
