I Have an Invincible Demon System in Me

As time went by, half a month passed.

In these half months, Tang Fei was low-key enough to stay at home and study and refine elixir.

Of course.

During this time, he naturally mastered the prescription of Yin Yang Dan.

Now, as long as he has the materials, he can refine the elixir.

And the success rate is extremely high, as high as 90%.

To know.

Such an amazing success rate cannot be achieved even by some Sipin Pharmacists.

But Tang Fei did it.

It can be seen that at this time, Tang Fei's refining technique can already stand up to the fourth grade refining pharmacist.

but.

As the Dan clan pharmacist's assessment is held only once a year, Tang Fei naturally has no way to assess the qualifications of the Sipin chemist.

"Tang Fei, in the next time, you can only learn by yourself. I really have nothing to teach you."

Calling Tang Fei forward, Yan Hong said with great care.

"Mr. Yan Hong teaches grace, Tang Fei will never forget it!"

Tang Fei's legs fell on his knees, and he immediately worshipped for three weeks.

"Come up, my old man didn't really teach you anything, but was influenced by you, and my popularity has increased by dozens of times."

Yan Hong quickly helped Tang Fei up.

And what he said is indeed true.

It is true that he introduced Tang Fei, but Tang Fei will have such a huge achievement, and it is indeed himself.

...

"Oh!"

At one moment, a deep muffled sound came from Tang Fei's body.

"Ding! Ding!"

"Congratulations to the host, successfully upgraded to the Spirit Sword Emperor Quadruple Heaven."

"Congratulations to the host, get a 'Dragon Fruit'."

"..."

"call!"

"Did it finally break?"

Tang Fei exhaled heavily.

For the breakthrough, he didn't have much surprise, because every time he refined, he could feel the breath in his body and grow quietly.

As long as it is growing, there will always be a breakthrough day.

And this day is finally here.

but.

What made Tang Fei quite surprised was that he made a breakthrough this time and got a 'Dragon Fruit'?

With a flick of the finger, suddenly a fruit appeared in his hand.

This fruit has a very strange shape, pure cyan, with a thick layer of skin on the outside, giving a very hard feeling.

"I've never heard of this fruit. If you eat it, it should produce dragon power in your body?"

Tang Fei muttered to himself thoughtfully.

Don't do it, don't stop.

When Tang Fei opened his mouth, he bit it down.

All the time, what the system rewards is beneficial to him.

He believes that this time, there will be no exceptions.

"Py!"

With a sip, Tang Fei's expression on his face suddenly became very ugly.

because.

The taste was so bitter that it was hard to swallow.

However, to the surprise of Tang Fei, the dragon power in his body was mobilized autonomously and became very active.

"This Dragon Power Fruit really strengthens Dragon Power!"

Thinking of this, Tang Fei suddenly didn't care about being unpalatable, and immediately opened his mouth and ate in a big mouth.

The unpleasant fruits are very different.

This is true whether it is the fruit of the devil or the dragon fruit in front of him.

After a while, Long Liguo was completely eaten.

Tang Fei can clearly feel that his own dragon power has more than doubled directly!
