Ye Yang's eyebrows beat violently, and the cold breath spread to his head in an instant, and then extended to his neck, chest, back, and even all parts of his body along 14 different lines.

Many parts of the body are itchy. Some places that may be "acupoints" gush out wisps of warm breath. Finally, they all converge on the chest. After rotating for three times, they suddenly separate.

One of the hot breath fell down to the Dantian about seven centimeters below the umbilicus along the Ren pulse, and the other cold breath returned to the center of the eyebrow.

The system menu he saw has changed:

……

Host: Ye Yang

Occupation: necromancer (LV5)

Status: normal

Power: 9+

Agility: 12+

Constitution: 15+

Intelligence: 14+

Skills: corpse resurrection, ghost fog, bone spear, summon skeleton, cross domain transmission

Mental strength: 97.5144.8

Upgrade energy: 0.45000

Free attribute points: 3 (please allocate attribute points within 180 seconds)

……

Without hesitation, Ye Yang added all three attributes to his constitution. With each addition, the breath at the center of the eyebrow and the lower Dantian converged on his chest, turned into a warm air flow and penetrated into his heart.

His heart was beating violently in his chest, and the warm current was transmitted to all parts of his body along the arteries and blood vessels. Every viscera, including spine, bone marrow, chest facial features and scalp, had a pleasant warmth.

After adding 3 points of physique, the system menu in front of Ye Yang jumps out a box: "do you want to deduct the skill points obtained by upgrading in exchange for a 'passive talent' skill?"

Ye Yang almost jumped up.

If your physique reaches 18 points, don't you directly obtain talent and deduct a skill point?

After hesitating for a while, Ye Yang looked at the word "passive" and bit his teeth: "change!!"

Passive talent, which is permanent, has always been maintained on the body. Unlike the "active" skill, it needs to be used actively to play a role, and it also consumes mental power. It's life-saving. It's okay.

Just a thought, the box disappears.

Ye Yang felt his skin itchy, as if countless little ants were crawling, and his muscles were beating violently, from the scalp to the facial muscles, to the neck, to the front chest and back, to the abdomen and thighs, as well as his arms, hands, feet, fingers and toes.

The organs in the body are also accelerating peristalsis. A feeling of acid and numbness after violent activities comes from all parts of the body.

"Well... What's going on? Something's wrong with the system?"

Ye Yang was stunned and a little scared.

Fortunately, this state lasted less than 10 seconds and stopped. There was a burst of acid fatigue all over the body. A sour smell exuded from the skin. When you rub it hard, there was a layer of oily dirt on your arm. And he was very hungry, very hungry, and kept making strange noises.

Ye Yang frowned and looked at the system menu first.

……

Host: Ye Yang

Occupation: necromancer (LV5)

Status: normal

Power: 9

Agility: 12

Constitution: 18

Intelligence: 14

Skills: corpse resurrection, ghost fog, bone spear, summon skeleton, cross domain transmission

Talent: copper skin and iron bone

Mental strength: 92.5146.8

Upgrade energy: 0.45000

……

"I got a talent, but the upper limit of spirit was increased by 2 points. Was it caused by the increase of physique? It actually affected the upper limit of spirit. I lost 5 points of mental power. Was it because I was too nervous that my mental power was consumed?"

Ye Yang's attention focused on the four words "copper skin and iron bone", and a box jumped out in front of him, with a text description: "copper skin and iron bone: passive talent, which greatly strengthens the ability of the body's skin to fight, puncture and cut, and greatly strengthens the ability of muscles and bones to fight."

Not detailed enough.

Ye Yang first ate something indiscriminately to make his stomach less hungry. He hurried to clean his body and then tested it.

Sharp knife, gently scratched on the hand, the hair was cut off, and there was no abnormality in the skin.

The strength increased continuously. After more than a dozen tests, Ye Yang used all his strength. The knife could only draw a white mark on the skin, but the white mark gradually disappeared after rubbing it with his hand.

Pick up the kitchen knife and slowly increase the power to cut. Finally, almost all the power of the right hand is used. The left arm is only painful, but the skin is not broken. Rub it a few times, leaving a red bruise on the arm, but rub it a few times, and the bruise disappears completely.

Then he took the screw and slowly increased his strength on his arm to drill. With great strength, he drilled a small hole. Blood penetrated out and wiped it quickly, but after a while, he felt no pain. After a closer look, the small hole had scabbed. It healed completely in less than ten minutes at most, and there was no scar left.

"Awesome..."

Ye Yang was stunned for a moment and couldn't help laughing.

This is invulnerable. What kind of golden bell covered iron cloth shirt? He doesn't know whether the ancients could practice to this extent before, but he can be sure that few modern people can compare with him in "horizontal Kung Fu".

"This passive talent is worth!!"

Next, continue to brush monsters, obtain "upgrade energy" and continue to improve your level.

Now, Ye Yang has come to understand that the so-called "upgrade energy" is likely to be something like "life energy" or "soul power". Creatures that must kill themselves absorb some power from each other's body at a close distance.

Zombies, from a biological point of view, are not really "dead", but a strange creature. Therefore, after killing, they can also absorb some of the strength of each other.

Killing mad dogs, pigs and chickens can provide varying degrees of energy. A few of these energies can be transformed into Ye Yang's spiritual power, and can also be accumulated to a certain extent to strengthen his body.

"It's understandable to have free attributes and strengthen yourself, but acquiring new skills and increasing skill proficiency can make skill variation stronger. What's the principle?"

I don't know this for the time being.

"By the way..."

Ye Yang thought of one thing. He still has two skills that can be upgraded.

……

Ghost fog (LV1)

……

Proficiency: 10241000 (upgradeable + ↑)

……

……

Bone spear (LV1)

……

Proficiency: 10351000 (upgradeable + ↑)

……

In fact, as early as before going to the first slaughterhouse, the proficiency of these two skills was enough. However, Ye Yang has been considering which direction should be improved if these two skills are upgraded?

In terms of enhancing combat effectiveness and lethality, increasing auxiliary effects, or enhancing life-saving ability?

Originally, he intended to keep it until it was needed, and then upgrade and strengthen it according to the actual situation, but now he has obtained a talent of "copper skin and iron bone". Ye Yang knows what direction he should strengthen in order to best improve his ability.

His attention focused on the arrow behind the "ghost fog" proficiency, and his mind fretted: "upgrade!!"
