In just over twenty seconds, the tracked robot vented all the missiles, causing severe damage to the Nightmare Beast, causing the waves that were about to condense to disperse. The black ink produced after the Nightmare Beast's extinction fell from the sky and actually extinguished the magma flames within dozens of kilometers.

The scene is quite spectacular, but Li Yuan has no time to enjoy it.

"Go quickly." Elizabeth stood on the Dragon King throne, nervous and her body kept bouncing. The collapse of the beasts was only temporary. More nightmare beasts gathered in the distance and would soon sweep over.

At this moment, the strange beasts in the center of the earth were afraid. After sacrificing two large leaders, they gathered at the largest crater and roared at the air, which sounded a little desolate.

Li Yuan also had no time to pay attention to the actions of these strange beasts in the center of the earth. Behind him was a large group of mechanical crazy bees, moving as the mecha moved, as fast as lightning.

Time is not long, Li Yuan has arrived at the edge of the abyss, and the Nightmare Bow has been suspended by the mecha, ready to launch a fierce attack at all times.

"What exactly is there below?"

"I don't know that the center of the earth and the gravity field of the star body are densely covered. I can guarantee that it is not a star gate, and no one will be so stupid that he arranges the star gate underground that it cannot complete the teleportation here."

"Let the mechanical crazy bee go down to explore first. Yu Zhengming left these little guys, probably just to let us throw stones and ask for directions. Hurry up and let me cover it." Li Yuan said, his fingers flexibly, and scenes appeared in front of him. He wanted to keep an eye on the movements of the nightmare beasts to the greatest extent, especially those ancestor beasts. The purpose of the archer is to defend the enemy from the range.

"Leave it to me." Elizabeth focused her attention on the mechanical crazi bees, causing them to swarm forward and sink to the bottom of the abyss.

Time passes slowly, and facing the overwhelming nightmare beast, ordinary people will definitely not be able to withstand this pressure. Even Li Yuan will occasionally raise his head and drink a sip of scorpion wine. He needs to use the beneficial ingredients in the wine to make himself perform as much as possible and make his thinking more active.

"Woooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooo

An ancestor beast roared in the distance, and then the beast group moved. They temporarily let go of the strange beasts in the center of the earth and gathered all their strength to pounce on Li Yuan. The high-ranking forbidden area believed that no matter how many tricks this human had, it would eventually collapse in the face of absolute strength.

"The effective killing radius is fifteen kilometers." Li Yuan's face was low, and his fingers were like plucking invisible strings, making a nice sound of Dingdong.

The sound is like a spring, and the murderous intent is overflowing the next moment.

"kill"

The arrow shadow has an unparalleled spirit, which is faster than the missile's piercing speed. In just a few breaths, the arrow shadow has become the main theme, and the front of the beast group suddenly sank.

This arrow consumes extremely fast. Every time you pull the bowstring, it will shoot out space fluctuations, causing thousands of long metal arrows to bloom.

After only ten bows were drawn, the beasts were hit by a fatal blow, Li Yuan had no arrows on hand except for retaining some powerful energy arrows. However, he had expected this situation to happen, so at the moment he escaped from Longmen Star, he sent pieces of broken metal parts into the synthetic tank and crushed them into powder.

If you want to make arrows by yourself, how can you do that? When Li Yuan went to Daxia to sell stolen goods, he forgot to buy a batch of qualified metal arrows because of the rush. Fortunately, he had gained nothing at Longmen Star, and stored a lot of high-level body remains. The metal used to create these bodies is definitely qualified to make metal element arrows.

After working day and night, the synthetic tank finally had sufficient reserves. Even Elizabeth's new shape was condensed by crushing some space-attribute metals.

"Arrows emerge like a rainbow, and the magnificent realm is inviolable." Li Yuan flashed off his coat, and dragon-shaped symbols appeared on his body, just like the dragon's neck roar, and he slowly closed his eyes.

When Li Yuan opened his eyes, his consciousness was closely linked to the mecha. He turned into a giant and stood beside the abyss, as if he could destroy the world with his every move and his aura was soaring.

"Hahahaha, it's not that easy to turn over me, I'm dead."

"die."

"die."

In such a vast underground space, Li Yuan's word "death" actually produces far-reaching echoes, just like surround sound broadcasts, you can hear it anywhere.

"Click"

The huge nightmare bow began to gather inward, first stacked from a hundred meters to fifty meters, then from fifty meters to thirty meters, and finally stayed twenty-five meters long, and was grabbed by Li Yuan.

The "good bow" dragon's magic turned into golden light, suppressing the big bow tightly.

After continuous attempts, Li Yuan can finally use the full power of dragon power to control this weapon. You must know that it is a weapon of the Nine Rings of Heaven, Nine Rings, and its energy circuits are linked together and flawless.

Originally, only the king of heaven could control this bow. Thanks to the curse mark, if the dragon power had not increased rapidly, the dragon power would have increased accordingly, and Li Yuan would not have broken the normal case.

The nightmare beast died too much, it was a process of building sand into a tower.

Although the strength of the Dragon Spirit has only increased by 9% of the 1000th, less than one percent, the meaning is different. It is an improvement that breaks the upper limit. In Li Yuan's combat power structure, it is definitely not as simple as one plus one equals two.

With a "duh", an arrow flew out.

The nightmare beast didn't care about the lonely arrow. However, the next moment, the arrow shadow penetrated into the beast group. Whenever the nightmare beast hit, the arrow shadow would not disappear, but would be divided into two and four, splitting wildly, and pierced through two thousand and forty-eight nightmare beasts in the blink of an eye.

"Ao Ao Ao"

After the piercing through, no nightmare beast survives. No matter how miserable their screams are, they will eventually collapse.

Li Yuan would not shoot just one arrow, but the Sky Nine Rings bow is in his hand, so how terrifying the lethality is, it can be seen from the arrow just now. Since he rarely uses metal element arrows, he naturally has to try it before officially launching an offensive. Fortunately, he grew up playing with bows and was obsessed with mecha archers since he was a child. He did not need specific parameters, and as long as he found the feel, the next thing was his world.

The arrow shadow appears again. The reason why the metal element arrows split and attack is because they are superimposed together by synthetic jars. Although this superposition can only be stored for a few days, mastering the heat will be a killer weapon.

From a distance, a section of the beast tide is like a bridge with bombs installed, collapsed in a stepped shape, and finally the black water poured down like a waterfall.

"Damn, this human attack power is close to the Mecha King. No, the Mecha King cannot consume energy like this. The little bitch Aladdin did not give himself to play for nothing."

"My Lord, although the low-end nightmare beast is just cannon fodder, this consumption is still a bit unbearable. I mean, I'm sending the ancestral beast army to fight, I don't believe that he can still kill so quickly."

"Hmph, a mere human being would use the ancestral beast legion. Cannon fodder is cannon fodder, which is useless. Go and convey my will. If anyone drops this guy named Li Yuan, I will descend on whom next time."

"Yes, Lord, your grace is like the rising sun, shining all things. We are willing to fight to the death for Lord." The toad-headed ancestor beast quickly went down to convey his will, and personally led a team of ancestor beasts to kill Li Yuan.

Elizabeth soon noticed that the nightmare beast was moving. About five hundred ancestor beasts were stepping on the heat wave, bulging up a blue energy field, and at a shocking speed, they entered the range.

Li Yuan took a deep breath. He knew that the visitor was not good, and the good ones did not come. Five hundred ancestor beasts were equivalent to the five hundred kings, and some were even advanced mecha kings. Even though the Tianjiu Rings Bow could regard fighting over-level battles as common, every time the mecha pulled the bowstring, it actually brought a burden to both arms. There was no need to worry about energy issues, but the mecha itself had an upper limit and could shoot up to fifty arrows.

On the battlefield, how can I think? With the sound of a "bang", the shadow of the arrow shot out again, launching a split attack.

"kill"

"kill"

"kill"

At this moment, all Li Yuan could do was to do his best to shoot these ancestor beasts in fifty arrows. Although it was not as satisfying as attacking ordinary nightmare beasts, the space power drawn from the curse mark was excellent. Almost every time three ancestor beasts were dropped, the strength of the dragon's strength could increase by two-tenth of ten thousand, equivalent to one-tenth of ten thousand per head.

Arrow shadows followed one by one. In order to increase the killing effect, Li Yuan even took advantage of the space power from the Shadow Dragon Cloak, so that Arrow shadow could break through the defense of the beast group more quickly. Moreover, the front arrow and the latter arrow can always be connected to the head and tail, aiming at the same point to attack.

This arrow is too tricky and cannot be defended on a large scale.

The space power contained in the Shadow Dragon Cloak is slowly weakening, and Li Yuan wants to share the space power absorbed by the Curse Seal to part of the Shadow Dragon Cloak. However, let alone whether the space power of the Nightmare Beast is suitable for the Shadow Dragon Cloak to absorb, the curse Seal and the Dragon Power can only be used in reverse for the Dragon Power.

Fortunately, fifty arrows are not a lot, and the Shadow Dragon Cloak can be consumed. In the future, just find an ancient battlefield and add some space fragments. If you want to say the space prop that is the least picky about food, it is the Shadow Dragon Cloak.

"boom"

The ancestor beast army reached a range of ten kilometers. Li Yuan unsuppressed the Heavenly King bow while releasing the dragon power, suppressing it with a scattered force, making the ancestor beast move slowly.

The person who was watching the battle in the distance was not angry. When the Ancestral Beast Legion set off, there were 500 Ancestral Beasts. With the range of the human ghost, nearly 200 died after reaching five kilometers, with a death rate of two-fifths. If a mecha was just jumped out of the distance, they would have such strength. Then their alien race would not be able to get stuck in this universe, and they would just roll the bed and go home and wait for death.

However, what was unexpected that Li Yuan put away his big bow, leaned back, and fell rapidly into the abyss of flames.

"No, there are ghosts in the abyss. No matter how much the price you pay, kill them for me." The order was directly passed to the ears of every ancestor beast.

Li Yuan's mecha fell rapidly, and from time to time, mechanical bees attached to it and wrapped the mecha in. In a moment, the mecha had become a round orb and fell at a faster speed.

The ancestral beast came in and pursued it in the abyss.

There were fires everywhere, and even the places where there were no fires at the bottom of the abyss, endless flames emerged. Li Yuan felt that Yu Zhengming was even more crazy than him. There was no star gate in the abyss, but there was another arrangement. He would complete the feat of crossing the center of the earth. There would be no mistake during this period, otherwise he would be doomed.
Chapter completed!
