One morning, Utan and the burly man walked so slowly, and the two of them finally failed to complete the ten round-trips stipulated by the old immortal, but the two of them had progressed from the first trip to half a trip to now be able to hold on to three round-trips.

Whew...

When the two of them rushed back to the huge waterfall, they suddenly sat down weakly, the breath in their noses was as heavy as the breath of a fierce ox, and the sweat on their faces was dense, dripping like a torrential rain, and their faces were pale and ruddy.

"Get up, get up!"

The old immortal suddenly came behind the two of them, one by one, and shouted.

"No... Whoa, whoa, whoa... Child... Scatter... Whew... Racked. Utan said breathlessly.

"Chrysanthemum cow!" the old immortal shouted.

Roar!

The giant horned rhinoceros, no, now has a mighty and domineering name, the chrysanthemum cow, rushed to the side of the old immortal, his eyes were shining, and he raised his giant horns, and he looked ready to go.

"Stab them until they stand up!" said the old immortal ruthlessly.

And his words were undoubtedly a very effective stimulant for Utan and the burly man, and the next moment, the two of them had to get up quickly without saying a word.

However, when he stood firm, his feet suddenly began to tremble.

Utan and the burly man could only glance at each other when they felt this gaffe, at least not alone, which was a comfort.

"Next, ten minutes, recover!" announced the old immortal.

The two of them were overjoyed when they heard this, and as soon as the old immortal words fell, they immediately sat down cross-legged and closed their eyes.

Boom!

The aura of heaven and earth around him suddenly became extremely violent in an instant, and it frantically poured into the bodies of Utan and the burly man like a bull in heat.

After the aura of heaven and earth flowed along the operation route of the secret method for a week, it was transformed into spiritual power, and the hungry spiritual sea suddenly erupted with unparalleled suction, and it was pulled into the spiritual sea by the suction without the need for Utan and the burly man to pull the spiritual power.

The empty spiritual sea was suddenly filled with a stream of spiritual power, just like a sluggish plant in the hot summer suddenly encountered a heavy rain, and a strange wave began to expand from the spiritual sea, spreading to Utan's entire body, and seeping into the muscles.

Bang bang!

Suddenly, the muscles of the two of them were frantically agitated, and the sleeping cells in the muscles instantly woke up, and the surging power gushed out of thin air, moisturizing every hungry muscle.

And it's an indescribable process of relaxation, going from one extreme to the opposite extreme, and the feeling goes without saying.

"Ten minutes to come!"

It wasn't long before the two of them enjoyed the comfort, and a nightmarish voice rang out.

The two of them had to wake up obediently from their cultivation and stood up with some reluctance.

"The second special training, do as I say.

Within three minutes, condense all the power in your body in your chest and poke it every ten seconds. The voice of the old immortal shook the eardrums of Utan and the burly man like thunder.

The next moment, the two of them hurriedly closed their eyes, their whole bodies were tense, and all the power in their bodies quickly surged to their chests.

As the saying goes, the country is easy to attack and difficult to defend, and it is easy to gather strength to the chest, but it is not so easy to control all the strength to gather in the chest.

"Two minutes!"

Utan and the burly man were both sweating profusely, and the power that was completely under their control was condensed in their chests and suddenly became violent, a little difficult to master, and this made them both unable to succeed until now.

"One minute!"

Damn it!

Utan and the burly man both cursed secretly, this was like a spring suddenly compressed, the whole body strength was condensed in one place, the rebound force was too great, no matter how the two of them concentrated, no matter how they concentrated, no matter how they concentrated, it would be useless.

"Ten seconds!"

"Nine seconds!"

...

"One second!"

The old immortal just wanted to say with a sneer, "You're finished"!

"It worked. ”

Utan and the burly man roared at the same time at this moment.

At this moment, it can be seen that their pectoral muscles are jumping violently, and each jump makes the air in their chests ripple violently.

"Hurry up, old man, what's next?" both Utan and the burly man shouted anxiously.

At this time, the corners of Lao Immortal's mouth suddenly hooked, he raised his hands unhurriedly, and his ten fingers clenched violently under the angry and puzzled eyes of the two, and in an instant, the two fists hit Utan and the burly man's chests lightly.

However, just such a light blow was an indescribable terrifying oppression to the two.

Knock knock!

Two heavy muffled sounds suddenly came from the chests of Utan and the burly man, and the power condensed in the chests of the two of them exploded like a balloon being punctured, and they rushed all over their bodies in a frenzy.

"Old man, what is this for?" Utan didn't know why, because he didn't feel any pain other than the strength of his cohesion being scattered.

The burly man was also confused and had to wait for the old immortal to answer.

At this time, the old immortal smiled and said, "Try to manipulate your strength again." ”

Utan and the burly man glanced at each other, and inexplicably closed their eyes and prepared to use the strength of their whole bodies.

Boom...

However, the power that stayed in the muscles of the whole body suddenly became extremely violent when the two of them wanted to operate, and they were actually resisting the control of the two.

"Do you know why the ** strength of spirit beasts is stronger than that of humans? Humans deduce that it is because of their huge bodies, and this is a misunderstanding at all. The real reason is that spirit beasts are born with the talent of using power, and they are much higher than us humans in terms of power differentiation, condensation, and operation, in other words, it is like the power we use is too mixed, and the power used by spirit beasts is very pure, which leads to the fact that there is still a gap in strength between spirit beasts and humans in the same realm and at the same level. At this time, the voice of the old immortal suddenly came into the ears of the two.

"And I condense all your power in one place, and then attack with my power, just to stimulate the reflex arc of power. The so-called reflex arc of power is instinctive resistance. When the subject carrying the force is oppressed by a strong external force without defense, the internal force will automatically respond to this stimulus, and the reaction to this stimulus will definitely not work with the current force, so the force will explode for a moment, and the result of the explosion will become violent for a period of time, making the subject unable to manipulate. Old Immortal continued to explain.

"Reflex arc?" Utan and the burly man were stunned, this kind of noun gave the two of them an indescribable strangeness, not only strange, but also seemed to have an innate sense of discomfort.

"Hmm! I'll just reveal a little bit to you both. There are many strange terms of this kind in this continent, which have been passed down from the continent's past, but they are only occasionally heard in continent-level territories that are one level higher than city-level territory. Old Immortal said.

"The past of the mainland?" Utan couldn't help but be stunned when he heard these words again, these words were also mentioned by Heiyin Chang, and he inexplicably thought that he should know the mainland's past very well.

"What's wrong?" the old immortal looked at Utan suspiciously.

"It's okay!" Utan shook his head, this kind of thing has no beginning or end and no need to know.

"Then hurry up and manipulate the current furious power while the power reflex arc has not disappeared, I don't ask for much, you just need to be able to fully use one-tenth of your power. The old immortal's tone changed abruptly, and he said sharply.

"How many minutes does this reflex arc last?" Utan asked.

"Fifteen minutes. The old immortal replied.

When Utan received the answer, he sat down on the spot and began to manipulate the forces of the rage.

Not to be outdone, the burly man was not to be outdone.

But manipulating manipulative forces is far more difficult than the two of them expected, they are so restless, like children with ADHD, you have a hard time settling them down.

I was born because of me, so I can't believe that I can't control you!

Utan tried to manipulate the mad force several times but failed, which made him extremely unhappy, so at this moment his mind became more focused, and he fought against the mad force with all his might.

And the burly man beside him seemed to be more relaxed, at least the old immortal could see that in less than five minutes, he had mastered a little strength, which was much stronger than Utan, who still had no progress.

"Heh, I know how to use the grievances of thousands of resentful spirits. At this time, the old immortal looked at the burly man and muttered.

This fifteen minutes passed quickly under the two of them's wholehearted manipulation and violent energy.

When the power in their bodies suddenly settled down as if they had been greatly stimulated, and they were completely at their disposal, they both realized that the reflex arc of the power was gone.

While the burly man managed to control one-tenth of the mad violence, Utan still made no progress.

"Get up, go on. Fifteen minutes later, the old immortal immediately shouted.

Utan and the burly man obediently opened their eyes, got up, and began to exert all their strength again, condensing towards their chests.

And this time, the burly man, both in terms of running power and controlling power, was much easier than Utan's position in the chest position.

The strength of both of them gathered in their chests, and their pectoral muscles suddenly agitated violently, shaking the air in their chests violently.

"Ninety-nine more non-stop, and you'll both have an hour's rest. ”

Yu Bi Lao's two fists hit Utan and the burly man again.

Bang bang!

The power condensed in the chests of the two suddenly exploded, and immediately after, the two quickly sat down, and immediately began to control the frenzied force.

"This time I have the power of three-tenths of the twentieth. At this time, the old immortal said to the two who had begun to manipulate.

Boom...

Utan ran into a frenzy of violence, and the latter suddenly became violently surging and surging until it shook off Utan's control.

"No matter how wild a horse is, there will be a day when it will be tamed!"

At this time, Utan gathered his mind and began to frantically stimulate the frenzied force.

However, when another fifteen minutes passed, Utan had not been able to control a bit of the madness, while the burly man could easily control three-twentieths of the rage.

This cycle continued, until the fifth fifteen minutes, and it was already required to control three-tenths of the furious force, and at this time, Utan was finally able to master one-tenth of the frenzied force.

By the time he reached half of the frenzied power, the burly man was already struggling, but at this time Utan had done it with great ease.

"Big brother, how do you do it?"

"It's very simple, it's hard to be soft!"
