Early the next morning, Su Hao began to practice iron cloth shirts.

In the copper skin realm, the main exercise is the strength and toughness of the muscles. Generally speaking, the body rubs against hard objects, which is called skin grinding. In combination with the special method of qi circulation and breathing, it can change the strength of the muscles bit by bit, and can wrap the body with a soft cloth to reduce muscle wear.

However, Su Hao did not use this method, but instead slapped his palms hard and hammered his muscles all over his body, making it even more violent. This is why he has the foundation of the Golden Bell Cover.

"Crack! Crack!"

Su Hao used his strength and slapped his muscles with both hands, pounding his whole body. Every time he slapped, he made a crisp sound. His strength violently destroyed his muscles, causing it to be red, swollen, swelling, and painful, and his skin torn and ripped, as if the skin was whipped by a stick or a whip.

Su Hao looked as usual, sat cross-legged, and used the Golden Bell Cover to heal the wounds. The true energy wandered all over his body. Soon, his injuries had almost recovered, and Su Hao began to repeat the previous tempering.

Every time he tempers, Su Hao’s muscles become tougher!

"It's almost done."

In just half a month, Su Hao's lower iron cloth shirt was already developed.

"laugh!"

Su Hao used the blade to slash past the muscles of his arm, but only left a light white mark!

In fact, Su Hao's fourth level golden bell cover can achieve sharp blades without any injury, but there are fundamental differences between the two. Su Hao used to use true qi to do this, but now it is the toughness of his muscles itself, without the need to use true qi to protect his body.

There is a big difference between the golden bell cover and the iron cloth shirt. Although the golden bell cover is a dual cultivation inside and outside, it actually mainly practices internal strength and advocates transformation from the inside out. The iron cloth shirt is pure external strength, which is very rough and directly tempers oneself!

He practiced into copper skin in half a month, of course, thanks to Su Hao's own profound skills. If he had no foundation, it would take several barrels of medicine to assist in the cultivation of copper skin, and it would take a long time. Su Hao directly omitted this step.

"The next is the middle iron bone realm, I need outsiders to help me practice!"

Su Hao stood up and practiced the middle iron bone realm of iron cloth shirt.

The practice of the Iron Bone Realm is even more brutal! In short, it is to use blunt objects such as fists, feet, sticks, etc. to hit the whole body hard, causing the bones to break. After healing, the bones will be tougher than before the shatter. Repeat the previous step until the bones finally reach the Iron Bone Realm!

It is like wrought iron, forging iron bones.

This is undoubtedly painful, and people with poor roots and bones can be forced to practice, and there is a possibility of losing their own practice.

But Su Hao had already tempered the golden bell shield before, and for him, it was just a step further.

"Master Wang Guan, I need a few strong warriors to cooperate with me in practicing martial arts."

Su Hao immediately found Wang Yu and asked him for a request.

"Okay, a small matter." Of course, Wang Yu agreed happily about such a small matter and helped Su Hao find several powerful disciples from Kong Wu in the martial arts school to be his auxiliary training.

"Really... want to fight?"

In the practice room, four or five warriors from the Iron Clothing Martial Arts Hall were hesitant when they looked at the thick sticks in their hands. This was a metal stick!

"Come on! Hit hard, as a warrior, don't let your mother-in-law do it, otherwise I'll hit you!"

When Su Hao saw the appearance of these people's mother-in-law and mother, he couldn't help but scold him.

"yes!"

Several warriors trembled in their hearts. They had seen with their own eyes the scene where Su Hao punched Zhang Kui and broke his bones.

"Bang bang bang!"

Immediately, these warriors gritted their teeth and beat Su Hao, who was standing like pine and cypress, with sticks on his body. Su Hao did not move at all, his expression was as normal as usual, which made them feel a little relieved and increased their strength until they finally used all their strength.

Su Hao restrained the Jin Zhong's true energy, otherwise he would use his true energy to protect his body. These warriors would not have hurt Su Hao with all their strength. Instead, they would have hurt their own bones. In that case, they would not achieve the effect Su Hao wanted.

"Crack!"

Su Hao restrained his true energy and used his body to resist the hard knocks of these warriors. He smashed them down one by one. Even if Su Hao did not use his true energy to protect his body, his bones also made a sound of bone cracks. The pain of bone cracks really penetrated into the bone marrow!

Soon, Su Hao's bones on his body cracked and he stopped practicing today.

"Sir Su Wu... let's help you go back and rest."

A warrior's worried Tao was full of admiration.

In his opinion, Su Hao's cultivation is already first-class, but when practicing martial arts, he is completely self-destructive and self-harm-like cultivation! Ordinary people can't stand it at all!

"No need, thank you for your hard work today."

Su Hao refused. Even though he was weak and sick when he was a child, he would not be able to support him, let alone now.

After saying that, Su Hao endured the pain from the cracked bones all over his body, turned around and left, returning to the room where he lived to recuperate.

"It hurts so much... I need to recover from the injury as soon as possible and continue!"

When he returned to the room, Su Hao was already in pain and sweating heavily on his forehead, but he gritted his teeth, took out a ginseng pill, swallowed it into his abdomen, and then used the Golden Bell Cover to heal the wounds to recover the trauma healing.

The medicinal power dissipated and the true qi flowed in the body, which made Su Hao feel numb and itchy all over his body, as if an ant was crawling, and the broken bones were healing again!

If the bones are damaged for 100 days, the bones of ordinary people will be broken. Even if they are strong, it will take two or three months to completely heal.

The physical recovery of a warrior is far beyond that of ordinary people, and he has to maintain it for one month or half a month.

But Su Hao's golden bell cover reached the fourth level, and the healing effect was amazing. With the top-grade ginseng, Shenmaru Nosuke, he only took five days to heal his bones as he had before!

"Not only that, it's a little stronger than before!"

Three days later, Su Hao was refreshed and moved his body. His bones completely healed and were a little tougher than before they broke.

"Okay, keep going!"

Su Hao was full of motivation and got up and went to the training room to continue practicing iron bones.

Soon, Su Hao dragged his painful body back into the house again and began to recuperate.

However, this time, Su Hao's bone healing speed was a little faster than before, and it took four and a half days to recover as before. This was Su Hao's bones transforming towards the Iron Bone Realm!

Although it is very hard, Su Hao enjoys it.

The third bone refining took only four days to heal! Su Hao's bone healing speed became faster and faster!

Not only that, the bones became more and more tough, and it became increasingly difficult for those trained warriors to hurt Su Hao.

It was not until more than two months passed.

"Bang bang bang bang bang!"

Four strong warriors surrounded Su Hao, waving iron rods to hit Su Hao's whole body, and the sounds that burst made people tremble.

But Su Hao's tall body stood there, motionless!

"No...no, Mr. Su Wu, I can't hold on!"

A warrior shouted panting, his eyes full of horror.

It has been a training session for half an hour, but even though they tried their best, it would be difficult for them to cause any damage to Su Hao!
