Due to the limitations of industrial standards, some instruments need to be ordered, and Baili Qingfeng did not start the test as soon as he returned home.

After putting down what he had bought, he went to a pharmacy, and outside the pharmacy, he took a box of layers of packaging from a person.

Coming to the courtyard with the box, he opened the box as soon as possible.

"Adrenaline ......"

Looking at the five syringes, Baili Qingfeng nodded.

Epinephrine, the main hormone of the adrenal medulla, forms norepinephrine in medullary chromium cells, and then further methylates norepinephrine to form epinephrine by the action of phenylethylamine-N-methyltransferase.

When an adrenaline arrived, Baili Qingfeng carefully sensed his own state and injected this adrenaline into his body.

Soon, Baili Qingfeng had sensed the changes in himself.

Nerve paralysis, reduced pain sensitivity, rapid heartbeat, blood boiling, and an inexhaustible energy all over the body......

"It is said that Super Saiyans can become extremely powerful when they are angry, and anger is also one of the mechanisms of adrenaline, is the so-called anger more powerful because of a large amount of adrenaline injection?"

Baili Qingfeng thought a little weirdly.

Sensing his own changes slightly, he quickly came to the training room, sensing his own changes.

Strength, reflexes, agility, and resistance to blows have all increased a lot, and the increase is almost as high as that of the Heavenly Demon Disintegration Technique.

If you can maintain this state of affairs all the time......

It can be regarded as the second level of the Heavenly Demon Disintegration Technique.

"Next, it's up to me how to use the stimulation brought by the Heavenly Demon Disintegration Technique to consciously guide the synthesis of adrenaline in the body, this is a difficult task, much more difficult than the creation of the One Hundred and Eight Styles of the Ancient Thunder God, I not only have to be prepared to stay up late, but also have to be prepared to stay up late for a long time, in order to overcome the difficulties, and truly create the second level of the Heavenly Demon Disintegration Technique. ”

After the test, Baili Qingfeng took a deep breath and consciously trained his adrenaline synthesis with a serious attitude.

Time passes.

Fast four days passed.

"Finally it worked. ”

That night, Baili Qingfeng breathed a sigh of relief.

"Although the Heavenly Demon Disintegration Technique is a popular exercise, it is of a very high level, even if it does not reach the level of the God and Demon Prison Body, the Ming King Treasure Body, and the Great Sun Golden Body Technique, I am afraid that it is not much worse, especially this method has great drawbacks, killing a thousand enemies and self-inflicting eight hundred, there is no martial artist who will bother to practice, so that I still took four days to perfect the second level when I had sufficient preconditions. ”

Baili Qingfeng moved his body slightly, expressing his satisfaction with the growth of his strength.

He didn't practice martial arts to beat people, just to not be beaten, and as his strength increased, this goal gradually approached him.

"Next, there is the Divine Demon Prison Body to practice, this method is much more difficult to practice than I imagined, the second level of the Heavenly Demon Disintegration Technique has been created by me, and the Divine Demon Prison Body is still mediocre so far...... Work hard, I want to work hard! The edge of the sword is sharpened, and the fragrance of plum blossoms comes from the bitter cold!"

Baili Qingfeng gets up every day and first sentences, first cheer himself up.

Give yourself encouragement in this way.

"Boom!"

Just when Baili Qingfeng created the second level of the Heavenly Demon Disintegration Technique, and was about to practice the Divine Demon Prison Body next, a slight vibration came from Qingyuan Mountain.

This kind of shaking sound formed a large shock wave, which made Baili Qingfeng have the illusion that the ground was shaking.

Fortunately, the jitter lasted for a second or two before stopping.

"I guess it was a truck that had a flat tire. ”

Baili Qingfeng muttered and ignored it.

It was already past eight o'clock in the evening, and the lights were blind, and he was a student, but he was not so curious to hear a little noise and ran into the mountains.

But tonight is destined to be uneven.

Less than half an hour after the roar came, a terrible scream came from the direction of the old dormitory area, and then, the screams continued to expand, more and more exclamations and shouts spread, and the aura of fear and horror quickly enveloped the small half of the old dormitory area, followed by an unknown roar.

The movement was so loud that Baili Qingfeng had to stop what he was doing and went up to the second floor, looking in the direction where the sound came from.

"It's over there, five or six hundred meters ......"

Baili Qingfeng took advantage of the terrain to look.

In the midst of the chaos, you can still see the ignited flames rising into the sky, burning half of the old city and dyeing the night red.

"Woooooo

The chaos lasted for about ten minutes, and the sound of sirens quickly sounded, followed by gunshots, mixed with inexplicable yells and human screams, which made the area seem to be in the midst of war.

"Something Happened ......"

Baili Qingfeng frowned, it stands to reason that this kind of thing should not be rushed by an ordinary person, it should be avoided from afar, don't get in the way, and leave professional things to professional people, but ......

Many houses in the old dormitory area had already burned and were blazing, and he rushed over to ask for nothing he could do, at least, to pour a few buckets of water and put out the fire......

After thinking for a moment, Baili Qingfeng finally turned back, took a sword, and walked out of the courtyard.

But when he walked less than 100 meters out of the courtyard, a burst of gunfire accompanied by screams came, and he was only fifty or sixty meters away.

The gunshots and screams lasted for about three or four seconds, and then quickly stopped, and then Baili Qingfeng felt a burst of heavy but compact footsteps rushing towards his direction from far and near, that is, the direction of Qingyuan Mountain.

"So fast!"

Baili Qingfeng's face changed.

At the moment when he was on guard with the sword in his right hand, a strong figure suddenly rushed out of the old city.

This figure ......

It looks similar to a human, but the height is only about one meter five or six, and there are some small differences between the body and the human, the arms are not only long, but the muscles are also high and bulging, full of explosive power, like a silver-backed King Kong.

Arm......

Height......

Dense hair tissue on the body......

Cavemen!?

Baili Qingfeng, who had studied in social studies for a year, recognized this creature for the first time.

Cave people are one of the most harmful humanoids to human society.

"Roar!"

This cave man obviously just escaped from the siege, he was shot several times and covered in blood, but when he saw Baili Qingfeng, he let out a beast-like roar from his mouth, and he immediately rushed towards Baili Qingfeng, that kind of momentum ......

It's like a tank rolling forward.

Fierce and tyrannical!

"Boom!"

Without any hesitation.

The sword in Baili Qingfeng's hand was instantly unsheathed.

Humans and humans have always been mortal enemies, and the hostile stance between the two can be seen from the fact that Shire University has several humanoids for students to study and study.

When humans and humanoids meet, there are often only two outcomes.

Die or become a slave!

The Baili Qingfeng Sword was unsheathed, and the Heavenly Demon Disintegration Technique was running at the same time, and with one step, the ground covered with many dead branches and rotten leaves seemed to be shattered by the force, and with this surging force, throughout the whole body, his whole person was like a sharp arrow that roared out, piercing the void, and stabbing the cave man who came to kill in an instant.

"Bang!"

Gold and iron intersect!

As the blade stabbed the caveman, there was a sound of gold and iron intersecting.

"Inner armor!?"

Baili Qingfeng realized something in an instant, and in the next second, the powerful anti-shock force was transmitted layer by layer to shake his sword-holding palm, making his palm burst into blood on the spot, and the famous sword in his hand was said to be made of high-strength alloy......

Bang clamble!

Then came the impact!

Just as Baili Qingfeng had previously relied on the powerful physique bestowed by the Heavenly Demon Disintegration Technique to crash the enemy and kill the enemy, this cave man who was less than one and a half meters tall was only shocked by his sword assassination, and he was already roaring wildly with the strength of the charge, and he slammed into his abdomen.

"Bang!"

Baili Qingfeng's whole person seemed to be bombarded by a truck, and the violent and terrifying force penetrated his abdomen and almost tore it apart, and his body also crashed thirteen meters faster than when he came, slamming into a wall, smashing that wall with a bang.

Smoke and dust rose up, and Baili Qingfeng's figure was quickly submerged by the falling bricks and stones.
