In the beginning, Han Yuliang added iron sand, a substance that has both earth and metal properties, to the fireball, so as to increase the lethality of the fireball.

But after a fight with Purple Cloth Sen Qi, he found that the power of the other party to stuff an iron core into the fireball is really strong, and his own iron sand core is really not enough.

However, once the iron sand core is melted into a pure iron core, it will lose its soil properties and will not be able to be controlled.

After realizing this, Han Yuliang thought of doing the opposite.

Since fire is not good for sand, what about sandbag fire?

Isn't the essence of the sharp thorn armor just sandbag fire?

But the sharp thorn battle armor is a bit of a taste of killing a thousand enemies and losing eight hundred.

Later, the improved stinger bomb needs to use a lifeform (at least a bug) as the "core", and the nucleus is too small and the power is also small, so it can be used to harass, but the actual combat is really not enough to see.

Finally, Han Yuliang remembered another magic.

Sand thorns.

The sand thorn is a mutation of the earth thorn, but it is very weak.

The sand system of the earth branch is not known for attacking, but for interfering with the battlefield and controlling the rhythm.

However, Han Yuliang found his way through the sand thorns.

When iron sand is heated to high temperatures, it becomes restless, which is actually caused by the high-speed movement of the molecular structure.

Under effective control, these high-temperature iron sand will form a high-speed exchange with the outer layer of cold iron sand.

In the process, the sand thorn will be like a high-speed oscillating arrow, full of destructive power.

However, this magic was five years ago, Han Yuliang only had an idea, and it was in these five years that it really became a burst arrow.

Because the principle of the Burst Arrow is simple, but there are two key points in practice.

The first is that the temperature of the core cannot be diffused to the outside, and if the sand thorn is heated as a whole, it will lose the high-frequency oscillation effect caused by switching between high and low temperatures.

The second nature is the speed of heating and cooling. The faster this speed, the faster the frequency of the oscillation.

Before, Han Yuliang couldn't do these two things anyway.

It wasn't until he learned a lot about Earth-based Plastics from Cass on Hell Island, and with Cass's training and help, he was able to finally solve the two most critical points.

The eyes of the three-headed dog of hell are indeed weak, but because they are weak, it is also extremely protective of its eyes, not only has a magic shield, but also has tough eyelids.

But neither of these stopped the power of the bursting arrows.

An arrow broke through the defense, and a fishy blood flower burst out of the poison head's right eye.

The intense pain made both the Fire Head and the Shadow Head immobilize, and the two ugly and disgusting heads gave up attacking Cass and turned their heads to stare at Han Yuliang.

The head of the fire opened its mouth and spat out a breath of fire.

Han Yuliang's fire thaumaturgy and a Hercules shield were able to block this breath.

He is better at dealing with fire heads than Cass.

Cass had already begun to condense a heavy earthen spear.

Over the past five years, he has taught Han Yuliang countless magical techniques, and he has also received many groundbreaking ideas from Han Yuliang.

Han Yuliang has a burst arrow, and he also has his own new killer weapon.

A closer look at his earthen spear reveals that it is a composite structure, with two layers of nesting.

If you can peel back the outer layer, you can see that in the center there is a sharp, long warhead condensed with the purest earth element and the hardest substance in the earth.

This whole earthen spear is actually an armor-piercing bullet.

Just when Han Yu Liang resisted the attacks of the three-headed dog of Hell, Firehead and Shadowhead. Cass's armor-piercing spear was finally ready, and he signaled it, and then used all his magic to project the armor-piercing spear out.

Backed by all of Cass' magical powers, the armor-piercing spear flew at an extremely high speed towards the poisonous head of the three-headed dog of Hell.

The Three-Headed Hellhound immediately sensed the danger, and the Fire Head and Shadow Head were raised, ready to resist the attack.

But Cass's signal to Han Yuliang was not in vain.

Han Yuliang killed the Hellhound's attack the moment it stopped, and a burst arrow stabbed Shadowhead's jaw, interrupting Shadowhead's stealth as he was about to use it.

The head of the fire then spits out the breath of fire.

In a short period of time, the flame breath not only had no blocking effect on the armor-piercing spear, but increased the power of the latter.

The three-headed dog of hell tried to hide at this time, but it was completely too late.

The armor-piercing spear was poisoning the head, and the outer layer broke through the magic shield, and the real armor-piercing part in the center successfully burrowed into the hard skull of the poison head.

A spear pierces the brain of the poisonous head.

The force almost ripped that ugly head off its neck.

The three-headed dog of hell was badly wounded and let out a cry of pain.

But Han Yuliang and Cass turned around and ran.

The Three-Headed Hellhound has an extremely violent personality, and it will be ...... under heavy blows

Just when Han Yuliang and Cass ran less than 100 meters away, a suppressed explosion came from behind them.

It wasn't an explosion in the ordinary sense of the word, but a powerful magical blast.

It's not loud, but it's amazingly powerful.

Visible to the naked eye, a blue magic ball with a diameter of fifteen meters appeared at the point of the explosion.

Above the magic ball was a non-stop flow of magic turbulence, and the turbulence formed one vortex after another on the surface of the magic ball.

Immediately after the orb appeared, it began to contract, as if there was a black hole in its core.

After three seconds, the orb shrinks to the size of a pintip.

A thousandth of a second later. The real outbreak began.

The sound was engulfed in an instant, as the air was blown out in an instant, creating a huge vacuum, followed by an infrasonic blast mixed with magic.

Cass summoned ten walls of earth in front of him, and then condensed all his magic into a Hercules shield.

Han Yuliang stuffed the little black cat into his arms, and then propped up his Hercules shield by Cass's side.

Cass's ten walls of earth were shattered before they could stop for even a second in front of the shockwave, followed by his Hercules shield.

The shockwave was blocked for three seconds, and then the Hercules shield shattered.

The last layer of defense is Han Yuliang's Hercules Aegis Sand Falls.

Hercules Aegis Sandfall is not known for its absolute defense, but is good at it.

The shockwave that rushed towards the two of them was weakened several times, and finally blocked in front of Hercules Aegis Sandfall.

Although the sand on the surface was blown away by the drastic cuts, there was always a steady stream of sand rising to replenish the consumption of the shield.

After five years, Han Yuliang no longer needed to use earth spar to use the Sand Waterfall Technique.

I don't know how long it took.

Maybe it's a few seconds, maybe it's ten minutes.

When Han Yuliang's eyes, ears, mouth, and nose were all shocked and bleeding, the impact from the outside finally passed.

He removed his shield and fell limply to the ground.

"Damn, that's exciting!"
