Above Liu Bi, there was a deep-water beast.

Four huge eyes and two huge heads like the heads of trucks sandwiched Liu Bi in the center like two trains about to collide and slammed into the past.

Judging from the size and ferocity of these two deep-water giant beasts, if this is implemented, Rao is Liu Bi's body is already very strong, and he is afraid that he will also be injured.

Under these hundreds of meters of deep water, if you are injured, the consequences are unimaginable.

Another problem is that Liu Bi's breath-holding time is now only a minute and a half, and if he can't get to the water in time, what awaits him will be the danger of suffocation.

Almost without hesitation, Liu Bi instantly struck out two true qi again, his body rose faster, and the deep-water giant beast that swooped down above his head had already opened its huge bloody mouth.

With sharp fangs and bottomless mouths, Liu Bi even asked about the foul smell coming from its mouth.

"Hah!"

With a low shout, the water above Liu Bi's head suddenly spun violently, and in just a moment, a huge palm had solidified in the water.

"Boom!"

A palm of the ecstasy palm was struck, Liu Bi's expression suddenly froze, although in the water, the destructive power of the dismal ecstasy palm was discounted a little, but this deep-water giant beast was not affected in any way, and even the speed of the swoop down was not weakened by even half a point, which was really too terrifying.

How to deal with it?

Liu Bi was a little nervous, under the deep water, time was pressing, if you want to escape as soon as possible, you must solve the trouble in front of you in the shortest possible time, otherwise you will wait for the one behind you to catch up, but I am afraid that I will really not be able to leave today.

In an instant, Liu Bi's thoughts were spinning rapidly, and the thinking speed of his brain reached the limit, and suddenly, a flash of inspiration flashed in his brain, and a resolute flash flashed on Liu Bi's face.

He simply put away his fists and threw his arms back hard, causing his rapidly rushing body to speed up a few points.

"Whew!"

"Karma!"

Liu Bi had even heard the loud "rattling" sound of the two rows of teeth of the deep-water beast coming together, but fortunately, his speed was extremely fast, and he rushed into the depths of the deep-water beast's throat in just one moment, and when the deep-water beast violently closed its mouth, its entire body had already passed its sharp teeth.

The stench, the strong stench stimulated Liu Bi, and he was so stimulated that he almost wanted to gag on the spot.

He struggled to press down on his tumbling stomach, and his right hand made a circle in the air, and then it shot out so unremarkably.

"Boom!"

"Whew!"

The sound of the deep-water beast's body exploding rang out along with its terrifying roar.

"Whew!"

With a foot on the inside of the deep-water giant beast's body, Liu Bi turned into a ray of light and quickly used the gap that had just opened up in the body of the deep-water giant beast with a punch of "Zhenshan River" and flew out.

Rise! Keep rising!

Liu Bi had already exerted his speed to the extreme, and looking back, the deep-water giant beast that had been punched out of the body by his punch "Zhenshanhe" had already struggled to sink to the bottom of the deep water.

"Wow!"

Finally rushed all the way out of the water, Liu Bi took a deep breath, and his brain, which had been a little faint, instantly cleared up.

After getting what he wanted, Liu Bi didn't stay longer, and flew down the mountain.

Back at Jinghai University of Traditional Chinese Medicine, it was the second day.

Looking at the fire spirit vines in front of him, the remaining half of the Heavenly Frost Fruit, and the other fifty-two Chinese medicinal materials on display next to him, Liu Bi's eyes flashed.

Now that you've collected everything, it's just a matter of refining it.

According to the content recorded above in the Pure Heart Qi Pill, this Pure Heart Qi Pill is not only difficult to find medicinal materials, but also the refining process is also very cumbersome, and it is easy to fail if you are not careful.

Now Liu Bi really can't afford any failure. There was only one copy of all the medicinal materials, and if he failed, he would never have a second chance, and the remaining time would not be enough for him to find the second batch of medicinal materials.

There is only one chance, if you don't succeed, you will become a benevolent!

At noon, Liu Bi deliberately found a restaurant and ordered a lot of things he likes to eat, he ate very much, and drank plenty of water, and when he returned to the laboratory, he felt that his various states were better than ever.

So he closed all the doors and windows of the laboratory, turned on all the lights, and came to the center of the laboratory alone and began to make preparations for refining the Pure Heart Qi Pill.

First of all, take out the Three Realms 7plus, in the treasure chest of the Three Realms 7plus, there is also an alchemy furnace that was snatched from the red envelope of Tiangong Xingjun, although the grade is relatively low, but as a thing in the fairy world, refining the pill of the mortal world, there should be no problem.

"Whew!"

A true qi was shot out, and a red flame gradually rose up in the Ding furnace, Liu Bi pressed one hand against the Ding furnace, and continued to pour the true qi into it, which lasted for about seventeen minutes, and the flame in the Ding furnace finally changed from red to light cyan.

Liu Bi saw that the fire was almost over, so he waved his hand and threw a medicinal herb into the Ding furnace.

"Bang!"

The flame in the Ding furnace suddenly expanded, almost swallowing all the medicinal materials, Liu Bi hurriedly pulled out a few true qi, which made the flame in the Ding furnace reduce a little, and then he could stabilize the state.

Under the continuous scorching of the flames, the appearance of the medicinal herbs became more and more dry, and a trace of cracks began to appear, and finally turned into a trace of flying dust and annihilated in the air, leaving behind the most essence of the medicinal power in the medicinal herbs.

After the purification of one medicinal material, Liu Bi immediately began to purify the second medicinal material, because the texture and structure of each medicinal material are different, and the heat required to purify each medicinal material is also slightly different.

In the past, Liu Bi had never purified these medicinal materials, because he had no experience at all, and everything needed to be explored by himself.

This urgently requires bold action, and it also requires careful care not to destroy the medicinal herbs, which is undoubtedly a delicate work.

From the afternoon to the early morning of the next day, under the sleepless rest, Liu Bi, who had always maintained a high degree of mental concentration, was finally a little tired, and when he felt a little mentally tired, he immediately stopped.

This kind of thing, only in the case of a high degree of mental concentration, Liu Bi can ensure a considerable success rate, if the spirit is sluggish, a careless, may fail.

A total of fifty-four purifications and one synthesis, there must be no mistakes, never allow a failure, never!

Two hours later, Liu Bi woke up from a state of deep sleep, for a truly efficient deep sleep, a person does not need two hours a day, only ninety minutes, can maintain a fairly mental state.

After Liu Bi woke up, he naturally became full of energy again.

I went to the bathroom in the laboratory to wash my face, ate some dry food and water at will, and after adjusting the state, Liu Bi entered the working state again.

From yesterday to now, he has successfully purified thirteen kinds of medicinal materials, and this is still under the condition that Liu Bi's divine sense is extremely powerful, and his perception of the flame and the degree of refining of medicinal materials is extremely keen, if he does not have such a powerful divine sense, just purifying these thirteen kinds of medicinal materials, I am afraid that it will take Liu Bi three or four days, and it may not be able to guarantee the success of all purification.

In this way, four days have passed quietly.

On this day, the work of refining medicinal materials was finally carried out to the end, and all the fifty-two kinds of medicinal materials had been successfully purified, and only the Heavenly Frost Fruit and the Fire Spirit Vine were left before they were purified.

These are the two most important herbs, and they are also the two most important herbs.

There must be no room for error!

Liu Bi warned himself this sentence over and over again in his heart.

"Zizi...... Zizi ......"

Under the scorching flames, the skin of the Tianshuang Fruit made a "sizzling" sound, bursts of green smoke came out, and the essence of the medicinal power contained in its body was being squeezed out of the body little by little.

The whole process, Liu Bi carried out extremely slowly, and he was also extremely careful, only purifying the mind and true qi consumed by this kind of Heavenly Frost Fruit, which was almost equivalent to the sum of the thirteen medicinal materials he had previously purified.

A whole day passed, and Liu Bi finally let out a long breath. Although he was tired at the moment, there was no doubt that he was very happy in his heart.

No matter how hard the process was, it was a success in the end.

Then, there was the last medicine: the fire spirit vine.

The process of purifying the Fire Spirit Vine was not at all easy compared to the process of purifying the Heavenly Frost Fruit, and it was precisely because Liu Bi worked so hard and was so careful that the result obtained in the end was not unexpected at all.

It worked, fifty-four times, all of them.

Now, it's the final step!

As long as the last step of synthesis is successful, the Pure Heart Qi Pill will be able to be refined, and Liu Bi, who is close to the edge of life and death, will also be able to carp and turn into a dragon again, rushing back to the vast sky, crisscrossing the four directions!
