Iron skin realm, the representative feature is that the skin of the whole body will become as black as ink, ordinary swords are difficult to hurt a bit, with the power of eight tigers, can lift 3,600 catties, open the monument and break stones, extremely powerful.

Now that Luo Ning's body has begun to be strengthened by black qi, his skin has quickly turned into a pitch-black color, and the amount of his body is also rising. The black air flow circulated on the skin on the surface of Luo Ning's body, and then entered the dense pores of the meridians in the body, and finally condensed into the dantian, slowly blending into the original red and yellow Tai Chi pattern.

Among Luo Ning's dantian.

The reddish-yellow Tai Chi pattern began to change, and the yellow merged into the black to become a dark gold. When red blends into black, it becomes dark red.

And the purple thunder and lightning represented by the demon pill of the Howling Wind Red Armor Tiger began to mutate after it merged into black, turning into a black-purple thunder snake, constantly hovering over the Tai Chi pattern.

"Crackling ......" There will occasionally be a slight crackling sound in Luo Ning's body, this black and purple electric snake is constantly stimulating Luo Ning's body cells, those cells are frantically absorbing energy, and the power continues to hit the limit of the body!

Three thousand two hundred pounds...... 3,300 pounds...... Three thousand four hundred pounds......

Cells grow rapidly, divide, knock out the weak, leaving the best ......

……

In the underground hall of the prison.

"The energy in Ronin's body continued to climb, and the skin began to show signs of hardening." "The blood energy has increased dramatically, and the pulse beat faster!" "The heart beats faster, and the strength of the heart beats is increased by two levels!" "The lung capacity has increased dramatically, and it has exceeded the average person by four times!"

The surrounding medical staff kept recording the changes in Luo Ning's body. At this time, Luo Ning, who was lying on the hypnotic bed, his entire body had completely turned black, and he looked like a human-shaped ink block.

"This is the Iron Skin?" Chen Yu looked at Luo Ning lying on the bed and muttered, "What a terrifying appearance, I'm really curious about what kind of strength he has now......

This process lasted for six hours, and at this time, almost all of the black qi on the Starfall Sword had been absorbed by Luo Ning, and the skin of his body had completely turned black, without a trace of dead ends.

"Hu ......" just as the last trace of black qi entered the body, in the Luo Ning body on this side of the earth. He opened his eyes suddenly.

On the big screen, the black layer of Luo Ning's skin in the dream world quickly receded, and there was no abnormality, and the offline hang-up started again.

"Ronin. You're awake. Chen Yu stepped forward: "Congratulations, you have officially broken through the Iron Skin Realm." Come with me, I think you must be curious about what kind of strength you are now. ”

"Yes, good!" Ronin was indeed curious.

He used to be just an ordinary person, but now he is marching towards the strength of the legendary superman. I just broke through today, so I naturally want to know what kind of Cheng Dù my strength has reached for the first time.

Soon, Luo Ning went to the previous gym again, and it was obvious that this gym had undergone a great transformation during this time, and all kinds of equipment to test strength were all in place, and even the fist tester was the latest model.

"Ronin, congratulations." The chief Da Da and Aoguan Haipu City and others were already waiting here, and when they saw Luo Ning coming in, the chief Da Da immediately smiled and said, "I have finally arrived at the Iron Skin Realm." At this level, even Zhao Zhen doesn't pose much threat to you, so you can just let it go later. ”

"Understood!" Luo Ning nodded fiercely.

"Let's try it first." The chief smiled and said, "Make a specific record of the number so that you can have a clear impression in your heart." ”

"Good!" Luo Ning nodded, and at this time Chen Yu came over and said, "The first test is still weightlifting, come with me." ”

This is where the test begins.

Because of the previous first test experience, Luo Ning was familiar with it this time, and soon the three basic indicators were tested, namely the weightlifting strength of 1950KG. THE MAXIMUM PUNCH POWER IS 7594KG, AND THE SPEED OF RUNNING AT FULL STRENGTH IS 7.26 SECONDS.

"This number is already quite terrifying," Chen Yu looked at Luo Ning's record and said, "Overall." The strength and speed have been greatly improved, and it is about 5% stronger than the one introduced in the forging cheats. The speed increase isn't huge, but the rest of the world in your dreams won't be much better than that. ”

"Hehe, it feels good," Luo Ning smiled happily like a child who had just gotten the latest toy.

"Alright. Then here's what's really important about this test. Chen Yu said with a smile: "Iron Skin Realm, according to the normal understanding, the skin can become hard and invulnerable, but we still need to continue to test whether there are other functions." ”

"Okay, no problem!" Luo Ning nodded, and then controlled the breath in his body, and in an instant, a layer of pitch-black color appeared on his arm, and Luo Ning moved: "It feels very good, come and try it." ”

"Okay, this time we can be a little slower and avoid you getting hurt." Chen Yu immediately clapped his hands.

Soon, two soldiers walked in with a large number of cold weapons.

This includes a wide variety of knives, spears, glaives, and more.

Almost all the varieties of cold weapons in ancient times in the world are available, and looking at the sword light on those weapons, it is obviously the best material for cold weapons on this side of the earth, made of cold steel.

"These knives are all made of cold steel," Chen Yu said, "and this is the best tool material that can be mass-produced on our planet at the moment." According to the properties of this material, it is about comparable to the second-grade knives in the world of your dreams. ”

Luo Ning had naturally heard of this thing in cold steel, and he immediately nodded: "Cheng, come on!" ”

Luo Ning exposed his arm, and now his skin was pitch black, and immediately a soldier took a cold steel dagger and put it on Luo Ning's arm.

"I'm going to start," the soldier cautiously slashed the dagger across Ronin's arm. He paddled very lightly, and he couldn't see that he was using any force. After all, Luo Ning affected people all over the world, and although he knew that the Iron Skin Realm had super strong defense, he still didn't dare to be careless.

There is no damage to the skin.

"Well, it's really good at the moment," Chen Yu nodded on the side: "You can increase the strength a little." ”

The soldier immediately grabbed the dagger and increased his strength.

Still unscathed.

"Okay, it seems that this iron skin is indeed the same as the legend," Chen Yu smiled and said, "The defense is quite strong. Now, then, add some more power. ”

With the experience of the first two times, this time it was much more relaxed.

This time, the soldier took a Japanese war knife made of cold steel, and then luckily, held the knife with both hands, and then slashed at Luo Ning's arm with a sharp swing.

With a "dang" sound, the blade of the cold steel knife popped out of a small gap, and Luo Ning's arm was only slightly dented by this knife, and it was still unscathed! (To be continued.) )
