Wanted to be a miracle doctor and became a defendant, so he decisively changed his career to become

Inside the gymnasium shrouded in yellow air.

When Song Bing stepped into it, the surrounding yellow air was isolated.

Look away.

Zhou Xuan, who was sitting cross-legged, slowly rose up.

The little black kids around were watching with their big black eyes.

However, they didn’t know that Song Bing’s brain power also covered them invisibly.

At the same time, several types of fused toxins accumulated in Song's sick kidney slowly turned into gas and flowed out.

90% of them gathered towards Zhou Xuan.

10% gathered around the group of little black people.

These toxins are what Song Bing has been exposed to and collected over time.

Such as the Andu poison gas he had just absorbed not long ago.

A colorful poison from a high spirit.

The southeastern rainforests absorb highly toxic miasma.

……

At this moment, Song Bing gathered all these poisonous gases together and sent them to Zhou Xuan and others.

The inspiration comes from Zhou Xuan's enjoyment of poison gas.

So Song Bing planned to give it a makeover when it was upgraded.

See if you can add a little poison to their farts.

This will definitely increase the lethality by more than a little bit.

"Uh...uh...uh...it feels so good..."

As the poisonous gas gathered, Zhou Xuan immediately revealed an intoxicated expression.

Even actively absorb you dare to believe it.

Even the body was poisoned and began to deform and rot.

He didn't feel anything.

Upon seeing this, Song Bing immediately cured him and upgraded him.

Feeling that this was truly a fifth-level [Furious Sky], Song Bing couldn't hide his surprise.

He really upgraded it himself.

But why is this?

Once a virus is born, its level is fixed.

Just like human genes.

How can I change myself?

"Could it be that I upgraded them and modified their disease genes, so they have the possibility of breaking through the limit and upgrading?"

Song Bing thought to himself.

Considering the situations of Zhou Xuan and the other two, this is the only possibility that makes sense at the moment.

But it is obvious that such a breakthrough requires harsh conditions.

Zhou Xuan and the other two were almost treated as experimental subjects by Song Bing, who underwent whole-body transformations regardless of their lives.

Zhou Xuan has been suffering from various diseases caused by Song disease since before the Apocalypse.

Song Shenglong had also been tortured by the Gao family through various experiments before the Apocalypse, and he himself was abnormal.

As for Wangcai, he seemed a little more normal, but when Song discovered his illness, he was still riddled with wounds.

It could only carry out comprehensive healing and transformation, and endow Song Shenglong with some tenacious life genes.

Therefore, these three are simply abnormal existences.

The diseases given are beyond the ability of normal people to bear.

For example, Zhou Xuan’s [Xuntian] is amazing, why not give it all to all the other little black people?

Wouldn’t there be many powerful Zhou Xuans this way?

The reason is simple, these little black people can't bear it at all.

One send will lead to death.

Although they had gradually been infected and blackened by Zhou Xuan, the two sides were not on the same level at all.

If Zhou Xuan was at the atmospheric level.

Then these little black guys are entry-level at best.

You can clearly feel it from the color and lethality of the farts of both sides.

This is also the reason why Song Bing only included the three Zhou Xuan brothers as experimental subjects.

So when faced with a desperate situation, the three Zhou Xuan brothers broke through human limits and seized this opportunity for a breakthrough.

On the other hand, Si Ya and others were all given diseases that Song disease could tolerate.

Even patiently assist in its integration.

That's why there is no Zhou Xuan and his three brothers.

Otherwise, Si Ya and the others were transformed by Song disease and should have made a breakthrough long ago.

In general.

The reason why the three Zhou Xuan brothers were able to make an incredible breakthrough.

It has everything to do with his illness and his own strength.

"Uh...uh...uh...it smells good, so good..."

Look, facing these poisonous gases that are enough to kill a level six person, Zhou Xuan is still enjoying absorbing them.

Even if the intestines are punctured and the stomach is rotten.

Which level 6 student dares to play like this?

"Ahhhhh..."

The little black men around were wailing in pain.

Nearly two thousand people cannot bear this 10% dilution.

Zhou Xuan drank 90% of it alone.

This is the gap.

Seeing this, Song Bing could only increase his brain power and frantically cure these people.

Once lost he heals.

All the soldiers of the Pi family will also die under these terrible toxins.

……

[Ding~ Successfully upgraded and fused [Xuntian] to level 1000000, merit -

The system named the new disease [Colorful Farts].

Symptoms: Farts are poisonous. Patients can produce and release six kinds of terrible colorful and toxic farts.

Each color fart has different toxicity and color, and can be used together...】

Soon, with the upgrade and fusion of Song Bing, countless poisonous gases flowed in, and Zhou Xuan's [Xuntian] was finally upgraded to [Colorful Fart Xuntian].

"Ahhhh..."

In an instant, Zhou Xuan, who was originally emitting black energy all over his body, suddenly became as powerful as a rainbow, and six farts of different colors rose into the sky from his body.

Like a bunch of rainbows.

Then it dispersed again.

It's like a light show.

Every fart exudes a deadly pressure.

"Wow!"

A group of little black men looked up, thinking it was so far away.

"Brother, this is an upgrade."

"Want Want..."

On the building, Song Shenglong and Wangcai looked up at this domineering fart, their eyes shining.

"puff…"

However, the next second, the rainbow fart turned into six beams of light and dispersed.

Suddenly, it was like six lights of different colors. Wherever they passed, they were like strong acid, corroding and destroying everything around them.

And just in time, a beam of green light was coming towards the building.

Wangcai and Song Shenglong's pupils shrank slightly. The man and the dog, who were usually ferocious, became more aggressive after sensing the stench emitted by the green light.

He quickly turned into a shadow and dodged.

"Wow..."

In an instant, green light flashed across the building, cutting out a corner of the entire building.

The man and the dog stared with wide eyes.

At the same time in the gymnasium, Zhou Xuan was upgraded to level six.

Song's illness did not stop.

But continue to upgrade.

He planned to upgrade this super combat power to level seven in one go.

“Ahhh…Puff…Puff…”

At the same time, the levels of the little black guys around were also rising.

Their farts also have colors.

But they are all very light, and each person only has one or two colors.

Or green.

Or red.

Either black or red.

This means that they only have a few types of toxins attached to them.

Of course, there are also several veterans, as well as the fifth-level Gao Shengjie and Yaomian, who have received special care from Song Bing...

As a result, the atmosphere in the venue began to become chaotic.

The entire stadium began to crumble, bearing more than it could bear.

[Ding~ Successfully upgraded [Colorful Farts] to level 10000000, Merit -]

I don't know how long it took, but the sound of successful upgrade rang out again.

"boom…"

The seventh yellow poisonous light was released from under Zhou Xuan.

His figure soared into the sky like a rainbow piercing the sun.

Straight into the sky.

"Rumble..."

In an instant, thunderclouds rolled over the sky and seven colorful farts swept across the sky, like thunder from the sky.

"This breath..."

Song Shenglong and Wangcai looked up at the sky and were stunned again. The man and the dog carefully felt this terrible breath and vomited on the spot.

"Ugh...it stinks!"

"Wang chou..."
