"The heart is like a mouth inside us. Pen & Fun & Pavilion www.biquge.info" Helissa said, "The tougher you exercise this mouth, the more blood will be stored, and when your heart muscle is stronger, you can practice dragon blood art, stimulate the blood in the body at will, increase strength, switch the state of the body, and can further control the flow trend and rate of blood in the body, and stop the bleeding by itself." ”

Dudian nodded slightly.

Even if Helissa didn't say it in such detail, as a modern person, he also knew the relationship between the heart and blood and the mystery in between, and he only needed a little bit to break it down.

"Elongated beat...... Helissa said as she approached Dudian's scarred chest and listened to the slow heartbeat in his chest.

Du Dian slowly stretched the heartbeat according to his words, and when he was elongated, it was like a person taking a deep breath, and the amount of blood inhaled was extremely rich, supporting the heart to the fullest, and then bursting out, and the blood suddenly flowed into all parts of the body at a very fast speed, and because the speed of flow was too fast, it instantly rushed into the arms and soles of the feet, causing both hands and feet to feel a trace of heat.

Seeing the effect, Du Di'an's eyes lit up slightly, closed his eyes, and concentrated on controlling his heart, stretching the frequency longer and longer, and the amount of blood he inhaled was even stronger.

Thump! Thump!

Every time it beats, it is like a muffled thunder in the chest, extremely loud.

Despite the extremely long intervals of the beats, the rhythm is steady, and each interval feels like a store and brewing.

"Yes, you realized it very quickly." Seeing that Dudian had understood the mystery, and autonomously lengthened her heartbeat and exercised her heart muscles, she couldn't help but nod her head with satisfaction, and there was a hint of appreciation in her eyes.

In the dark ice cave, time flies without realizing it.

I don't know how long I exercised, Du Dian gradually felt a little tired, and his control of his heart was a little weak, and at the same time, there were bursts of hunger in his abdomen, as if there was a black hole that could suck his whole body in.

He opened his eyes and immediately saw Helissa staring at him, his exhausted heart beat a little, but soon regained his composure and said, "I'm hungry, let's eat something first and then practice." ”

"Okay." Helissa retracted her gaze and nodded, she had been practicing for so long for the first time, it had exceeded her expectations, and she should be tired by now.

"These two bone-eating rats, you eat one, just leave one for warning." Helissa said, pointing to the two bone-eaters on the ground who were cowering in the corners.

Du Dian glanced at it, shook his head slightly, and said, "It's better to keep it, this little thing doesn't have any meat, I'll find something else to eat." ”

"No, it's too dangerous to go out now." Helissa said immediately.

Seeing her resolute appearance, Du Dian's heart warmed, and he smiled: "I didn't say that I wanted to go out, I wanted to find food, I didn't have to look for it myself, I could also let the food be delivered to the door by myself." ”

"Huh?" Helissa was slightly stunned and looked at him suspiciously.

Du Dian first put on the battle armor and the bone-eater rat suit on the ground, at this moment the heart returned to normal beating, and the heat on his body was gradually subsiding, he had to keep warm and find food to fill it as soon as possible, the heat promoted by blood flow alone could not be maintained for a long time after all.

He picked up the dagger from the ground, went to the water at the mouth of the cave, and cut his arm with a scratch, and blood slid down and dripped into the water.

When he was exercising his heart before, he thought of this method, using blood to lure the underwater monsters in the vicinity.

Although he didn't see any underwater monsters nearby in his thermal vision, he knew that the drainage channels in this city were interconnected, and even if some were blocked by collapsed roads, they were only a few after all.

And the underwater monster's sense of smell of blood in the water far exceeds the range of his thermal vision, which is very promising to attract monsters.

Seeing Du Dian's actions, Heilisha suddenly came to her senses, knowing Du Dian's plan, her lips moved slightly, and she silently came behind Du Dian, without saying anything.

When the blood stained red on the surface of the water, Du Dian covered his wrist, controlled the heartbeat, lengthened the heartbeat, sucked the blood into the heart, and the wound on his arm immediately stopped the bleeding.

Instead of forcefully bursting the blood out in one go, he slowly squeezed it out of his heart, which required greater control.

The squeezed blood flowed slowly throughout his body, and before it could reach all the veins in his arm, he twitched his heart again to suck the blood back, and so on that the cycle was repeated, and no more blood spilled from the wound on his arm.

Seeing Du Di'an's actions, a glint flashed in her eyes, and she whispered, "You have learned to stop the bleeding on your own." ”

Du Dian nodded slightly, as long as he learned to control and knew the principle of stopping bleeding, it was not difficult to do this, but with his tired state at the moment, it was more difficult to maintain such a state of heart control.

More than ten minutes later, the wound on the arm had been glued together after the bleeding had stopped.

Seeing this, Dudian stopped controlling his heart and allowed it to return to its normal beat, while also breathing a sigh of relief.

At that moment, a red hot spot appeared in his thermal vision, swimming rapidly from four o'clock, as if it were coming straight to the surface of the water.

Du Dian stared at the concentration of this heat source, and breathed a sigh of relief in his heart, it was only the level of a hunter, and the volume was not large, only less than two meters, which was petite for an underwater monster.

"Here we are." Heilisha said, "I'll solve it, you can rest." ”

Du Dian didn't look back, and said, "I'll do it, you don't need to do anything about this kind of little thing." ”

Helissa glanced at him, her lips moved slightly, and just about to say more, the underwater monster had already swam rapidly in front of the two, no more than ten meters away.

With a cold glint in his eyes, Dudian put one hand into the water and swung it as bait.

This underwater monster resembles a giant shrimp, with a curved barb on its tail and a row of sharp bone spurs erected on its back, which looks more hideous.

Dudian stared at the water, and at the moment when it was about to pounce, he suddenly retracted his hand into the water.

Strike!

The shrimp-like monster suddenly jumped out of the water, as if it was about to jump up and eat the bait.

However, when it jumped out of the water, it suddenly saw Dudian and Helissa squatting on the shore, their blood-red eyes hidden deep in its carapace slightly constricted, and their bodies writhed to jump into the water.

Dudian slammed his hand, the dagger stabbing straight down its head, and the fist of his previously retracted hand slammed into the carapace beneath its abdomen, thudming it against the ice wall opposite the puddle.

Before it could slip off, he quickly turned his fist into a claw, grabbed its body, and threw it into the ice cave behind.
