Looking at Tang Juyi, who rushed directly up the stairs, Ya Wushuang was still immersed in the shock brought by the "20 bottles of small life elixir", and only said to Lan Tian after a while:

"This guy runs a pharmacy at home?"

…………

Although the posture of stepping on the stairs first was beautiful, Tang Juyi's drop speed of his health at this time was extremely embarrassing.

After entering the area covered by this viscous black fluid, Tang Juyi felt a strange sense of peeling, followed by weakness due to the excessive contrast in strength.

His physical fitness instantly returned to the level of ordinary people, and of course Tang Juyi could no longer do any difficult actions such as walking like flying and jumping three feet, and even the speed of climbing the stairs was slower than he expected.

Every time he lifted his footsteps, he would have to slow down because of the burning pain coming from the soles of his feet and the viscous adsorption force of the black fluid, and just running half of the stairs had already made Tang Juyi consume a lot of physical strength.

"Health has dropped to 88%."

Glancing at his status bar, Tang Juyi's heart sank, and he realized that the rate of loss of health was far faster than he expected, so he increased his speed again.

When he stepped on the stairs on the second floor, Tang Juyi's health had already dropped to 85%.

"Okay...... Not a particularly big loss......"

Secretly calculating the consumption, Tang Juyi also quickly completed the action of reversing the direction with the help of the handrail, and walked up the stairs from the second floor to the third floor.

However, it was this moment that made Tang Juyi's face change instantly:

"Not good!"

Unlike the staircase between the 1st and 2nd floors, the black fluid between the 2nd and 3rd floors is thicker, and the corrosive burning effect is also more intense, causing the health to be lost at a rate of 2% per second, which is twice as fast as before!

"I made a mistake in the calculation, but I didn't expect the degree of wear and tear on different floors of him to change......"

Tang Juyi immediately realized the impact of this loss change, and quickly began to make further calculations for the next journey:

"If there is an increasing pattern between this, then on the stairs between the 3rd and 4th floors, the level of health loss can be close to 3% or even 4% per second, in which case, simply staying in the hallway for five seconds will be equivalent to the amount of health lost in a small life potion......

It was at this time that Tang Juyi immediately calculated his approximate loss on the entire journey:

"It took 7 seconds to get up the stairs in the first stage, then the next two phases will take about 8 seconds and 10 seconds respectively, and if you take the worst-case scenario, plus the initial deduction of 5%, the loss will reach 68%, which is close to 70% of the health......"

With a more and more solemn mood, Tang Juyi immediately conceived two options:

1. Rush to the 4th floor quickly and minimize the time you spend on your stay, so that the loss will be minimized, but if you encounter other dangers, you will immediately fall into a very critical situation.

2. Allow 2 seconds for the next two flights of stairs to use the Life Elixir, so that although there will be about 12% more loss out of thin air, you will be able to enter the 4th floor in a relatively healthy state.

Considering that the current "owner" of this hospital is probably not a good-hearted person, Tang Juyi almost acquiesced that there would be a malicious design similar to "open the door to kill" on the 4th floor, so the first choice was naturally abandoned.

Immediately stopped, Tang Juyi quickly took out a [Life Elixir-Small] from the storage space, and then poured it down with a tilt of his neck, and then immediately accelerated and sprinted again.

After crossing the 3rd floor, Tang Juyi's health value not only did not lose under the replenishment of the potion, but even rose by 1%, so he quickly connected to the second bottle of the potion, after the effect of the potion, to maintain a good state of life.

Sure enough, as Tang Juyi predicted, on the steps from the 3rd floor to the 4th floor, the deduction rate of health points reached a terrifying 4% per second, just stepping on the stairs, Tang Juyi could feel that the vitality and vitality in his body were rapidly draining.

Tang Juyi, who ran and crossed with all his might, was very calm, although the multifaceted discomfort in his body was constantly transmitting bad nerve signals, but he still controlled his body and made the most streamlined and efficient movements.

Finally, with the leap of the last step, Tang Juyi didn't have time to brake, and directly rolled forward into the corridor on the 4th floor, and his HP finally stayed at the level of 72%.

"Hoo ......"

Quickly leaning against the wall, Tang Juyi directly drank the third bottle of life elixir, and it was not until he threw the empty glass bottle aside that he had the opportunity to observe the scenery on the 4th floor.

And this glance made Tang Juyi's pupils shrink instantly.

At the same time, Lan Tian and Ya Wushuang, who were waiting for Tang Juyi to deliver the news, both heard the sound of "Zizi", and then received a signal from Tang Juyi's extremely fast speech from the communication period hanging next to their ears:

"The health loss between different floors will increase by a double trend, so be sure to stock up on enough life potions...... And also...... Anyway, don't go up to the 4th floor......"

After another burst of signal noise, Tang Juyi's voice was completely interrupted.

Ya Wushuang immediately pressed the reply button and tried to contact Tang Juyi again:

"How's it going over there? Talking? ”

However, no matter how Ya Wushuang asked, no response was heard during the communication period.

Of course, Lan Tian heard that the situation on Tang Juyi's side was grim, so he also showed a worried face:

"He's probably in big trouble."

Ya Wushuang turned off the communicator very unhappily:

"Of course I knew he was in trouble, but his tone of refusal of all support made me want to give him two slaps in the face."

Subsequently, Ya Wushuang also looked at Lan Tian:

"You also heard what he just said, I have more life potions than you, so I will be in charge of the third floor."

After speaking, without waiting for Lan Tian to agree, Ya Wushuang had already rushed up the steps.

Lan Tian watched Ya Wushuang's figure disappear around the corner, and also said to himself with some dissatisfaction:

"One by one, they all like to be heroes......"

…………

On the corridor on the 4th floor, Tang Juyi turned off his communicator and then withdrew it into the storage space, and at the same time looked at the corridor in front of him, showing a self-deprecating smile:

"You really took good care of me...... Wouldn't it be too thoughtful to welcome me with such a big formation? ”

In front of Tang Juyi, the entire corridor was shrouded in moss and vines, like ancient human ruins in the primeval forest, and even the doors and windows of those wards were penetrated by vines, spreading all the way into the wards.

What is terrifying is that there are also a lot of "decorations" inlaid on the wall on the 4th floor, and if you look closely, you will find that they are one after another corpses with tragic appearances!

The corpses, some dressed in hospital gowns and some in lab coats worn by medical staff, had the only thing in common was that their expressions were equally full of pain and fear, and many areas of the skin surface were burrowed with plant branches and leaves, and even the mouth and nose were covered with sinuous vines.

These plants actually use these corpses as nutrients!

What's even more disturbing is that with Tang Juyi's intrusion, these corpses embedded in the wall actually moved one after another, and even broke free from the shackles of the wall, trying to climb out of those reinforced concrete.

The old and mottled walls didn't seem to be able to contain the living corpses, and as they howled, chunks of wall skin and cement shattered and fell off, freeing them from the horrors.

Listening to the howls one after another, Tang Juyi only felt a headache:

"Okay, okay, I've received all your blessings, thank you for your kindness......"
