These hard objects, very popular with black skeletons and rock giants, are not as delicious as meat and plants, but they can be highly evolved when swallowed raw.

Today's black skeleton, many bones on the body have turned into different metal colors, and the newly grown bone knife bone sword has also become an iron sword and bronze sword - the names iron and bronze are all black skeletons that come out of their minds.

It even knew that steel was harder than iron and bronze, but now the white skull's blackstone fire was not hot enough to burn steel.

The rock giant also likes these metals, since eating the metal, its entire surface has become black and dull, covered with a layer of iron armor, although the iron armor is not thick enough to withstand the full attack of large monsters, but the teeth and claws of small and medium-sized monsters will only slip on the iron armor, and it takes a lot of effort to penetrate.

And this little time difference was enough for the rock giant to smash the enemy with an iron fist.

Time flies, it's harvest season again, and the young monsters hanging from the crops are ripe and roaring loudly, but the black skull is not busy preparing for the harvest, and it and the white skull, sitting on the shoulders of the rock giant, nay, the iron giant, now should be called, strode towards the sea.

The black skeleton came to the cliff of the sea, standing with its head held high, although the sea breeze was strong, but it could not blow the fire in its eyes, suddenly, the black skeleton opened its mouth, and an invisible sound wave flew out of its mouth and flew towards the sea, secondary waves! This is a secondary wave! After the change of diet structure and the swallowing of a large number of rare metals at the same time, the black skeleton has evolved by leaps and bounds, and it has evolved a vocal organ, but in the form of secondary waves.

The secondary wave seemed to have a shape, and it crashed headlong into the sea, stirring up waves like a wall!

In the distance, there were several loud roars, and then, several silver threads flew from the sea and sky, it was the Sour Sea Giant Snake!

The annual harvest season in the valley is also the time for the sour sea basilisk to come ashore for a feast, but this year, the Black Skull has challenged the basilisk! The land is mine! You can only stay in the sea of acid!

The Sour Sea Basilisk was furious at the Black Skull's provocation, once upon a time, they were too pressed by the powerful races in the valley to go ashore, and later, a cataclysm caused the race to relocate, and the Sour Sea Basilisk turned the valley into a place of their annual feast. But today, a small creature would dare to stop them! Go to hell!

A sour sea basilisk more than 30 meters long swam in the front, its body coiled and flicked, and it jumped up the cliff that was insurmountable for ordinary basilisks, and with one mouth, it pounced on the black skull.

The black skull didn't move at all, and even curled up slightly, when the basilisk swallowed it in one bite, the black skull screamed, and the iron and bronze swords in both arms came out, and at the same time, countless small gears popped out of the joints of the body, and the gears rotated at high speed, and together with the iron and bronze swords, the basilisk was in a mess.

Poor basilisk, before he could even let out a scream, he was drilled by the black skull from seven inches to the tail inside, and when the black skull slashed open the genital cavity of the tail and drilled out, the basilisk fell to the ground softly, already dead.

The black skeleton wiped the flesh and blood of the basilisk on its body, and its metal skeleton was corroded by the basilisk's acid, only slightly dim, which did not affect its movement in the slightest.

The other basilisks saw their companions being tortured and killed, but they didn't stop attacking - this is the nature of the beasts of this world, the more they fight, the stronger they get, the more they flinch, the more they flee, only the fight to the death! Die!

This time, the basilisks learned their lesson and never swallowed the Black Skeleton alive again, relying on their hard scales to ram the Black Skull again and again.

The Black Skull is strong in combat, but it suffers from its small size and light weight, and every time the basilisk hits, it will be knocked into the air like a pebble, and even the cunning basilisk keeps whipping the Black Skull with its tail, making it like a spinning top, and it spins non-stop.

The black skull's iron sword, bronze sword, and bone spurs could not hurt the basilisk's scales this time, and in the incessant slashing sound, the basilisk's scales only had thin scratches.

The Iron Giant let out a low roar and was about to step forward to help the Black Skull, but the White Skull gently patted it on the shoulder, signaling his big friend not to be impatient.

The black skeleton really didn't need help, it seemed that it could only be beaten and couldn't fight back, but in fact, it didn't suffer much damage, in fact, it kept adjusting its body, every impact or whip of the basilisk, only very little force touched its body, it actually seemed to be teasing the basilisk.

The basilisk slowly sensed that something was wrong, and one of the basilisk suddenly turned around and pounced on the iron giant and the white skull standing aside, the black skull was furious, it suddenly opened its mouth, and a stream of infrasound waves rushed towards the sneaking basilisk, and the basilisk was suddenly attacked, and the scales on the outside were not damaged at all, but the internal organs inside were all powder.

The sneaking basilisk was in mid-air, and it fell hard, and when it hit the ground, it was already frozen and motionless, only a wisp of blood oozing from the corner of its mouth.

The black skull's move to kill the enemy is invisible, but it can scare the sour sea basilisks, they just came to eat a big meal, but they didn't expect to meet such a hard ballast, the snake is cunning, and has never been willing to fight hard, otherwise, they will not escape to the sour sea, use the sour sea to protect themselves, and now the strong enemy is current, the basilisks only have one thought left, that is, escape!

The sour sea basilisk screamed, no longer entangled with the black skeleton, turned and fled, however, the black skeleton was unwilling to let them go like this, only to see the black skeleton open its mouth again and again, and a series of secondary waves flew out of his mouth. This series of secondary wave controls was so subtle that it only shattered the basilisks' eyes, but did not kill them directly.

One by one, the basilisks became blind, and the more panicked they became, the more they scurried around, and even stumbled over each other, opening their mouths and biting indiscriminately.

Only then did the black skeleton turn around and wave his hand to the white skeleton, meaning to let the white skeleton step forward and practice with these blind basilisks. The white skull clapped its hands lightly, as if applauding the black skull.

The Iron Giant couldn't help it anymore, stepped forward and grabbed a scurrying basilisk, smashed its head flat with just one punch, pulled out the snake heart and snake gall from the basilisk's still writhing body, and threw it at the white skull.

The white skeleton took out two iron meteorites from his bosom, struck each other to provoke sparks, and then lit the hay he carried with him, and lit a fire to roast the snake's heart and gall.
