My health recovery is incredibly fast.

"Hmm? Don't look at me like that. I don't mean to look down on you. In my opinion, your muscle strength is about this level right now."

Rexol twisted his wrist, and the heavy hammerhead drew a circle in the air.

"Regardless of the type of cold weapon used, the most important part of the body is the wrist!"

"Remember this."

"A flexible wrist allows you to attack from more angles. A strong wrist can withstand more recoil. A resilient wrist reduces strains and recovers from muscle tears faster. A powerful wrist is more threatening. An explosive wrist determines how quickly you can take down your enemy."

"Only wrists with this kind of strength can fully control the chain hammer."

Rexol gripped the hammer handle, his wrist rotating along the trajectory of "∞", the metal hammerhead swinging back and forth, whistling through the air.

"Follow my movements. Bend your wrist as far as you can."

Shazo began to swing the wooden chain hammer.

"Don't move your arm!" Rexol pointed at the other man's elbow, his words stern. "Just twist your wrist and use the strength of your wrist to move the hammer."

He stopped what he was doing and walked halfway around Xia Zuo. "Yes, that's it. It seems that long-term alchemy and writing haven't atrophied your wrists."

Xia Zuo's wrists were very flexible, and after getting used to the weight of the wooden chain hammer, he swung them with increasing amplitude.

“Turn your body to the side and extend your right arm straight forward,” Rexol instructed. “Don’t let the hammer hit you.”

Xia Zuo did as instructed.

The hammer, which originally drew a figure eight on a vertical plane, gradually began to circle back and forth on both sides of the body.

“Good dexterity; in terms of wrists alone, you have a talent for manipulating chain hammers.”

Rexor dragged a wooden stake covered with sheet metal from a corner of the training field. "Come on, try hitting it with a chain hammer. Get the hammerhead at the right distance from your right hand, and make sure it hits the target squarely. Feel the chain. Remember, you can only swing your arm, not your waist, and your feet can't move."

"Yes, Master." Xia Zuo stood in front of the wooden stake, estimated the attack range, first swung the chain hammer, letting the hammer head rotate twice on his side, and then swung it hard.

"Pop." The wooden hammerhead struck the sheet metal and bounced off.

"Hmm...not bad talent. The chains can help you build up momentum for your attack. But there isn't much time for you to spin your hammer in a fight."

Rexor said decisively:

"Attack directly, don't charge up!"

"Pop." Xia Zuo swung his chain hammer again and struck the wooden stake.

“Keep going, keep going, don’t stop. Adjust your movements, find the right way to generate power, don’t twist your waist, and don’t move your feet when attacking. If you can show great talent, I’ll consider reducing your tuition.” Rexol said, arms crossed.

"Really?" Xia Zuo perked up immediately when he heard that he could pay less.

Rexol found the other man's greedy look somewhat amusing and said with a smirk, "Of course."

“Okay!” Xia Zuo gripped the hammer handle tightly and squinted as he thought.

The bald man is not allowed to use his waist strength, nor is he allowed to move his feet.

That means that lunging forward and backward, and swinging the hammer head sideways are not allowed—although this is a good way to generate power, it mobilizes almost all the larger muscles in the body, as well as the core area of ​​the abdomen and some leg power.

Is the bald guy trying to test someone's explosive power?

Xia Zuo disagreed.

Rexor just stated that his strength is only at the level of a 12-year-old Witcher apprentice.

Therefore, the focus of this test has nothing to do with strength.

Xia Zuo recalled Rexol's words one by one.

Feel the power of the chains...

Xia Zuo raised an eyebrow, probably understanding the bald man's intention.

The purpose of lunging and swinging the weapon horizontally is to accelerate the weapon tip over the longest distance to accumulate kinetic energy.

This method is generally used for straight-barreled weapons—the connecting part between the tip and the right hand is fixed, and the weapon tip can only be accelerated by drawing a large arc during an attack.

But the chain hammer is different.

Between the right hand and the hammerhead, there is an additional chain that can be used to change positions.

When the chain hammer is swung forward, the hammerhead follows behind.

The hammer head will only strike forward when the arm stops swinging.

This means that when the chain hammer is swung forward, the hammer head will travel a short distance with additional acceleration.

The key to maximizing the power of the chain hammer lies in making good use of this acceleration period.

Xia Zuo instantly conjured up an elliptical trajectory on a horizontal plane in his mind.

The person is at the midpoint of the ellipse, with the major axis aligned with the target, and moves their right hand along the edge of the ellipse from right to left.

There is a slight delay before the hammer strikes the target.

Therefore, it is necessary to ensure that the hammer head hits the target precisely when the right hand has passed three to five centimeters along the long axis, in order to ensure that the hammer head has traveled the longest acceleration distance.

Haha, master alchemy, and you won't be afraid to practice with cold weapons.

Thanks to the giant creation science for its contributions of torque and geometry knowledge.

Xia Zuo smiled, raised the chain hammer, gripped the hammerhead with his left hand to straighten the chain, and measured the length of the entire chain hammer.

He adjusted his stance, simulated the swinging process several times, memorized the bending and stretching of his arms, and finally swung with force.

"boom."

It hit the target squarely, and even the sound of the impact changed, becoming deeper and more powerful, leaving a shallow dent in the metal sheet.

"boom."

"boom."

Xia Zuo hammered the wooden stake again and again, gradually becoming more skilled and increasing the force of his swings.

Rexol adjusted the details of his elbow twist and gave him some instructions:

"Not bad, Xia Zuo. But don't use too much force. Save some strength to prevent the enemy from changing their moves and to protect your joints."

"Whether it's a light or heavy chain hammer, there are only a few ways to attack."

"The first one, which is what you're doing right now, is swinging, used against a single enemy."

"The second method is a sweeping motion, where you slightly bend your arm and sweep away the target in front of you."

"The third method is armor penetration. If your enemy has a shield, you can use the chain to hit the edge of the shield and let the hammer go around to attack the enemy."

"When using a chain mace, accuracy is the most important factor. Power is secondary. This is because the heavy, sharp hammerhead can penetrate enemy armor, tear through cotton linings, and shatter their bones."

Rexor clapped his hands, signaling Shazo to stop, then walked to the weapon rack. "The chain mace has obvious drawbacks too. Let's have a spar."

Xia Zuo stopped swinging his arms, took a few breaths, and rubbed his slightly numb right arm. Just that short while ago, the force of the recoil had made his muscles tremble.

He took the small leather round shield from the bald man and put it on his left hand.

Rexor had the same setup, but his metal chain hammer had been replaced with a wooden one.

"When defending against an enemy attack, always remember that you are blocking the tip of the weapon, because that is the only place that poses a threat."

Rexol patted the small round shield. "This kind of shield is perfect for training your reaction time. Its area is just enough for you to block a small area. You have to use it to protect yourself and block my hammer."

As soon as the bald man finished speaking, he waved his right hand forward.

Xia Zuo quickly gripped the small round shield and blocked it.

"Clang!" A tremendous force came from my left hand, and the tingling and numbness went straight to my palm and elbow.

Xia Zuo gasped and shook his left hand.

"Don't forget to attack! Counterattack immediately after you break through, this is your chance." Rex's roar echoed as he swung his chain hammer once more.

Xia Zuo's left hand was a little weak, and he crossed his legs and stepped back.

Rexol pressed his advantage, smashing his chain mace down on his opponent with a whooshing sound. "If you were on a real battlefield, you'd be dead already! You're using a chain mace, not a longsword. You can only attack forward or flank, never retreat!"

Shazo retreated all the way to the wall, with nowhere left to go, and Rexor's hammer slammed into the wall beside his head.

"Remember, do not retreat. The chain mace is only a threat when swung! It is not a longsword, where the blade points at the opponent to stop the enemy."

Rexol walked onto the field, "One more time."

Xia Zuo heard the roar of blood rushing through his ears. He took a few deep breaths, walked silently toward the bald man, stared intently at him, twirled the chain hammer in his right hand, and launched the first attack.

His hammer traced an arc, just missing Rexor's hammer, and the two chains became entangled.

Rex's shield slammed into Shazor's right hand, the edge of the shield striking the back of his hand.

Xia Zuo cried out in pain as the chain hammer fell to the ground. Just as he was about to pick it up, he looked up again and saw the opponent's shield slam into his face.

"Bang." A pleasant sound is a good start.

Xia Zuo fell backward to the ground, his clothes covered in dust.

Rexor pulled him up. "That's the downside of the chain mace. Its chains are easy to get tangled in. Enemies on the battlefield won't be friendly and help you untangle them. You'll temporarily lose most of your fighting ability before you defeat them and break the chains."

"What should we do then?" Xia Zuo shook the chain and unlocked the two chains.

Rexol pulled a uniquely shaped chain hammer from his pocket.

It looks like a hammer.

The dark gray metal handle, engraved with a honeycomb-like anti-slip pattern, is connected to a hammer head larger than a fist. Six sharp, melon-shaped metal blades are evenly distributed on the hammer head, and the sharp edges of the metal blades increase pressure, significantly enhancing the destructive power.

"This is an elemental energy chain hammer. It can be used as a nail hammer. When necessary, you can infuse it with attribute-less energy, like this."

The light in Rexor's hand pierced into the handle, and with a swing of his right hand, the hammerhead shot out, trailing a white energy chain behind him. After the hammerhead reached its maximum distance, it was instantly retracted by the energy chain and fixed to the tip of the handle.

Xia Zuo raised an eyebrow.

This weapon is ingenious! The energy chains have no physical form, so there's no risk of them getting tangled. When not being charged with energy, it can also be used as a hammer.

"You want to learn?" Rexol read his expression and handed him the Elemental Chain Hammer.

"Want to learn... Holy crap!" The moment Xia Zuo took the hammer, his shoulders suddenly slumped. The Yuan Energy Chain Hammer was incredibly heavy, bending his back.

Xia Zuo gritted his teeth and used all his strength, but still couldn't lift it.

The Elemental Chain Hammer slammed into the ground with a bang.

"Huff huff..." Xia Zuo panted, hands on his hips, and looked down to use his detection spell on the Yuan Energy Chain Hammer.
