Of course, Tang Zheng did not forcibly break into Wu's room, and the dove occupied the magpie's nest, so he could only continue to settle on the sofa in the living room.

In the dead of night, he was sleepy.

Because, tonight he was going to take Long Yuan Dan to improve his strength, the newly refined Long Yuan Dan did not have such a powerful medicinal properties, and he wanted to test whether he could take it safely.

Calm your mind and get rid of distracting thoughts.

He sat down cross-legged and swallowed a Long Yuan Dan, and as soon as the Long Yuan Dan slid down his throat, it exploded, turning into a ball of energy and rushing towards the eight veins of the Qi Jing.

Tang Zheng had already had a countermeasure, focusing on three purposes, running the Heavenly Ancient Scroll, the Chaos Vajra Technique, and the Dragon God Technique.

The three exercises run in their own mysterious paths, and the true qi is surging like a river.

The energy of Long Yuan Dan was quickly reduced to zero, and little by little it was transported to all parts of the body.

Whew!

The energy traveled around the bones, penetrating into the bones little by little, and the snow-white bones began to glow with a metallic sheen little by little.

The energy of a Dragon Yuan Dan was quickly refined, and his skin glowed with a metallic luster, shining in the night, like a bronze man.

"The Chaos Vajra Technique has improved again. ”

Tang Zheng was overjoyed.

During this time, he had been cultivating the Tongtian Ancient Scroll and the Dragon God Technique, but the Chaos Vajra Technique had neglected to cultivate, but he didn't expect that the energy of the Dragon Yuan Pill would be of great benefit to refining his physical body.

The Chaos Vajra Technique requires constant refining of the physical body in order to make the skin and muscles extremely powerful.

At the beginning, in the 100,000 mountains, he went through the secret medicine of the Wu clan to quench his body, and then he went through the baptism and tempering of magma in the cave of the Holy Land, and then he reached the copper skin realm.

In the past few months, the Chaos Vajra Technique has not improved, and at this moment, he couldn't help but be overjoyed when he discovered the magic of Long Yuan Dan.

This is the energy of Long Yuan Dan refining the physical body, and it turns out that the Chaos Vajra Technique needs to be tempered by external force at the beginning to reach the copper skin realm.

But once this realm is reached, the next stage is the iron bone, however, the bone cannot be tempered from the outside, only from the inside of the body, which requires enough energy to temper the bones inside the body.

In the past, Long Yuandan's energy was too strong, and every time he took it, he almost exploded and died, where did he have the heart to refine his bones.

Thinking of this, Tang Zheng couldn't wait to take another Long Yuan Dan.

Most of the energy was used to refine the bones, which showed that the energy contained in the new Long Yuan Dan was much smaller, and it was also within the controllable range.

Whew!

Long Yuandan's energy continued to refine the bones, and the metallic luster on the bones changed from light to dark, and finally turned golden.

When the bones of his whole body were tempered once, he felt that his body was countless times stronger, and the Chaos Vajra Jue had risen to a higher level, reaching the second realm—Iron Bone.

Now, ordinary external forces not only can't hurt his skin, but even can't help his bones, and the ability to resist blows has increased exponentially.

He really wanted to find someone to stab him with a sword and test his body's ability to resist blows.

"Anyway, there is a ready-made candidate, so I will use her to test my Chaos Vajra Technique, and she will also grit her teeth with hatred for me, giving her this opportunity to vent her anger. ”

He rolled over and stood up, knocking on Takeshi's room.

"Who?" asked Wu warily.

"Me, haven't you slept yet?"

"What's the matter?"

"Since you didn't sleep and got up, I have something to do with you. Tang Zheng said.

After a while, Wu opened the door and walked out, looking at Tang Zheng with a suspicious expression, especially since there was still a layer of metallic luster on his skin, which was obviously not there before.

Wu looked at him in surprise and asked, "What the hell are you doing?"

"I know you're mad at me, and I have a lot of them, giving you a chance to vent your anger. Tang Zheng said with a smile.

Wu Hu looked at him suspiciously, not knowing what he meant.

Seeing that he didn't understand, Tang Zheng explained: "Let's find a place to make a move, I won't fight back, let you attack." ”

Wu Xiuqi's eyebrows were raised, and he felt unbelievable at his almost masochistic request, but he immediately felt very relieved.

Since you took the initiative to commit cheapness, then I can't blame me.

"Okay, where to go?"

"Go downstairs. Tang Zheng walked to the window, jumped into the high-rise building, and jumped off the more than ten floors.

He was like a big bird, hidden in the night, and was not discovered, when he landed more than ten meters, his toes slammed on the wall, and the speed of his fall accelerated a few points.

Seeing that he was about to fall to the ground, his toes touched the windowsill of a house again, and he removed most of his strength, and landed steadily, lifting his weight lightly, without making the slightest sound.

Wu Ruying followed, and fell to the ground immediately after, but he was not as light as he was, and he made a lot of landing sounds.

Tang Zheng pointed to a small forest next door to the community, flew away, only to see an afterimage sweeping across the night sky, he climbed over the wall of the community and landed in the grove.

Wu's face had a different color, because she thought that she couldn't do Tang Zheng's Cheng dù, and she felt both helpless and unwilling for his speed of progress.

At the beginning, he was much higher than him, why is he being compared now?

She couldn't help but feel a sense of powerless frustration in her heart, but in an instant, her eyes became firm and she chased after her.

This time, I must give Tang Zheng a good look, and vent my evil anger for the master and the master.

The night was watery, the groves were pitch black, and only the occasional bits of moonlight peeping through the clouds could make out the surroundings.

The two had excellent eyesight and were not affected by the darkness, and stood at each other.

"Attack me with this knife, and I won't fight back. Tang Zheng handed Wu a big knife and said.

Wu weighed the broadsword with his hand, it was indeed a sharp blade with cold light. She looked at him in disbelief and asked again, "Do you really want me to attack you?"

"After this village, there will be no such shop, and if you want to attack me in the future, it will not be easy. Tang Zheng said provocatively.

"Since you are asking for your own hardships, then I will fulfill you. Wu let out a low sigh, and the wide-backed broadsword slashed at Tang Zheng's chest.

Bang!

Tang Zheng was slashed backwards by this force, a crack appeared on his coat, and his slightly golden skin was exposed.

However, there was no blood and no wounds.

Wu looked at this scene in shock, she only used thirty percent of the strength of this knife, but she didn't expect Tang Zheng to really not resist, and she took a knife, but it was unhindered.

Wu also knew that some people in the rivers and lakes would practice kung fu and pride themselves as copper and iron, but she knew that many people were bragging indiscriminately, and they didn't want to dodge if they were really slashed, and if they were cut down, they would take half their lives.

But Tang Zheng was obviously different from those fake tricks, he really used his body to resist this knife.

"No matter what kind of kung fu you practice, eat my second sword to see if you will still be unharmed. Wu Qian rushed a few steps, and the big knife slashed down, only to see the sword light lit up with a strange red light in the darkness.

Tang Zheng's pupils shrank, and he recognized that this was her mental method of casting the Flame Knife, usually, she made a knife with both hands, and at this moment the internal strength was completely attached to the knife body, as if the knife body was burning, much more powerful than the big knife itself.

Tang Zheng didn't retreat, he bent his knee back with one leg, and pressed against his body, seeing the "burning" big knife approaching, he puffed up his chest.

Boom!

Tang Zheng slid backwards, sliding a furrow in the ground, and finally, he broke a tree before he stopped and fell to the ground with a bang.

Wu was stunned, this time she used ninety percent of her strength, the power of this knife was enough to crack the stone, and she suddenly remembered that she had used such a ruthless knife in anger, so would Tang Zheng be split in half by him.

If this is the case, then I will not be able to account for my master and my mother.

She threw away the big knife, hurriedly rushed over, and shouted in shock, "Tang Zheng, how are you?"

Tang Zheng lay on the ground flatly, the taste of this knife was not pleasant, a bright red mark appeared on his chest, and his clothes had been completely torn by the big knife, revealing a hard chest, but fortunately there was no blood, that is, no skin was cut.

Wu Mu looked at this scene dumbfounded, and said, "I am such a powerful knife, are you still safe and sound?"

She has always believed in the strength of her shots, but seeing Tang Zheng's ability to resist blows against the sky, she still can't help but feel a deep sense of powerlessness.

Tang Zheng is not as comfortable as it seems on the surface, although he is copper skin and iron bones, but his body still has pain, bearing such a big attack force, the muscles in his chest are almost torn, and the pain of the bones about to fall apart makes him almost collapse.

At this moment, the true qi surged wildly in his meridians, trying to calm the heart-rending pain, and the energy of the Long Yuan Dan, which had not yet been completely refined, also became agitated, merging with this surging true qi, turning into a wild horse galloping freely in his meridians.

Gradually, his body became extremely hot, like a large furnace, and his original metallic skin turned fiery red, and his whole body seemed to be on fire.

"Damn, it's too bad, I still underestimated Long Yuandan's energy, I originally thought that there would be no big problem after refining the bones, but I didn't expect that these residual energies would have such a powerful power, and when I was weak, they actually detonated my pure yang power. ”

Tang Zheng couldn't cry or laugh, he was too light on the enemy, especially during this period of time, the power of pure yang was very quiet, so that he neglected this fatal flaw.

Now the power of pure yang has exploded, what to do, this is not a joke.

He could already feel the heat in his body, and the dew on the blades of grass around him had been roasted and evaporated by his heat.

"Hey, what's wrong with you? You told me to attack you, you can't blame me. Wu said.

He supported the ground with both hands, and finally stood up, gritting his teeth and walking in the community without saying a word, but he could walk on the wall of the ground, but at this moment it became an insurmountable mountain, which could not be climbed at all.

"You're going home, I'll take you back. Wu held him in a panic, and he was about to jump towards the community on his tiptoes.

But Tang Zheng smelled a hint of fragrant fragrance on the tip of his nose, and a steady stream of pure yin power passed from between the two skins, just like a drug addict encountering drugs, his reason was instantly submerged, and his whole body became extremely hot, and his hands hugged her thin waist at once.

I don't know where he got the strength, he grabbed Wu's clothes and tore them hard, and with a stabbing sound, a big crack was torn open in Wu's chest, and his snow-white skin was exposed.

When he landed, Tang Zheng's eyes were red and he pounced like a beast, and Wu only had time to scream before he was thrown to the ground.

"Tang Zheng, you rascal, you are looking for death!" Wu slapped his palm on the shoulder, but he didn't realize it, he just wanted to rub each other into each other's bodies.

And he's hot all over, like a soldering iron.

She instantly thought of the beautiful scene in the 100,000 mountains, and subconsciously exclaimed: "He is sick again, and the power of pure yang has exploded again!"
