The advantage of the tracking arrow is that once it is locked, it will chase the enemy to the end.

【System】You kill the Stinger Rats and gain 1000 XP!

It turns out that the original name of this big rat is a highly poisonous stinger rat, no wonder it can come and go freely in the poisonous fog, it should be a kind of poisonous monster itself.

The rat that floated to the surface was quickly swept back by the turbulent current, and Jia Zhengjin remembered the gold ore that it had robbed, and immediately jumped into the water again, quickly swam to the side of its corpse, and grabbed it and searched it carefully.

However, there is no news of the gold mine on the corpse, could it be that it has sunk to the bottom?

Jia Zhengjin threw away the corpse, dived underwater with bated breath, and sank about fifteen or sixteen meters before barely finding the bottom layer of sand.

Luckily, night vision quickly spotted the looted gold ore, which was being washed and tumbling underwater.

He sped in, quickly grabbing it and tucking it into his virtual backpack. When he looked up, he found that he had been pushed from the clear groundwater to the turquoise venom river, surrounded by huge miasma tree roots, which continued to pollute the groundwater downstream.

Before he could surface on the water, behind the roots of the surrounding trees, a large number of scarlet eyes suddenly appeared, illuminating Jia Zhengjin like lanterns in the water.

Surprised by this situation, he quickly took out his trident and looked around nervously. It's just that the body is still constantly pushed back by the current.

"Boom~" As he kept moving along the green venom river, the "lanterns" behind the roots of the trees all moved outside, and it turned out to be a large group of huge reptilian creatures in the shape of crocodiles, all staring at him with very murderous eyes in the water at this time, as if he was the prey.

What the hell is this? Jia Zhengjin is not afraid, and with his current equipment, he doesn't need to worry at all.

"Blah!!" these crocodile-like underwater crawling creatures quickly chased the backward Jia Zhengjin along the river, and the largest of them suddenly rushed over, opening its bloody mouth and biting fiercely.

"Block and counterattack!" Although Jia Zhengjin was not used to fighting underwater, he still used his skills smoothly.

The trident easily blocked the opponent's huge mouth, and then stabbed out violently.

【System】You kill the poisonous Dakras and gain 3,000 experience points!

No wonder it looks so similar to Dakras, it's a mutant at all!

The companion was killed, and the bloody breath seemed to make the poisonous Daklas in the water excited, and began to frantically besiege and bite from all sides.

Jia Zhengjin was unhurried, using a trident and using flash skills to entangle with them, constantly killing each other.

Seeing that the last poisonous Dakras was left, and was about to break with it, his body suddenly flew out of the air, directly out of the venom.

Jia Zhengjin landed quickly in the air, only to find that the water had reached its end, forming a venom waterfall in a steep place, pouring down frantically.

I was swept out of the waterfall by the venom river, and after flying outside, of course, I fell straight down.

"Poof!!" Thankfully, there's a huge underground lake down there, and it's very deep. fell from a height of 100 meters, and received no other injuries except for the pain in his back on the water.

Jia Zhengjin, who fell into the venom lake, sank thirty or forty meters and did not see the bottom, and during the period of emotion, he saw that the highly poisonous Daklas also fell from a high altitude, and he looked a little dizzy when he fell into the water.

"Poof!" he quickly swam over and pierced the trident's head before the other party could react.

All the poisonous Daklas were eliminated and rushed upwards to the surface. Holding his breath underwater made him very uncomfortable, and although the venom did not hurt him, it didn't seem to taste good in his mouth, and it had a strong fishy smell, which was particularly disgusting.

I finally swam to the lake, and when I got ashore, I looked around carefully, and on all sides were even more huge miasma tree roots, God knows how huge this miasma tree is.

The underground has become like this, no wonder the miasma trees above are spreading so quickly, making it impossible for the Wing Clan to resist at all.

But then again, where is the exit? The rats have been killed, and the gold mine is in hand, so it's time to go back to the surface and ask about the Nelakh vein.

Flying up from here, crossing the waterfall and looking back to find the cave you dug up, you should be able to return to the surface easily, right?

Jia Zhengjin took out the scout aircraft and equipped it, and just as he was about to take off, a large number of giant beetles suddenly appeared around him, surrounding him in an instant, and even the sky was blocked by the flying giant beetles.

"Sneer——!!" These beetles are all green, and the venom they spew out is also emerald green, coming from all directions, and the sound is quite amazing.

Jia Zhengjin quickly took out the Gaia Aegis and raised it above his head to protect himself.

Aegis Gaia works, reflecting 70% magic.

It seems that the venom of these giant beetles is a magical attack.

【System】You kill the Poison Gu and gain 5,000 experience points!

【System】You kill the Poison Gu......

This venom attack seems to be quite powerful, and it can kill them in an instant when it is reflected back.

However, it is clear that these strange beetles, called Poison Gu, have no IQ at all. Obviously, so many companions were killed by reflected magic, and they were still desperately spitting venom to attack.

As a result, Jia Zhengjin didn't do anything, just hid under the Gaia Aegis and waited slowly, and it didn't take long for all the poisonous Gu around him to die cleanly.

Just as he thought it was over, an even bigger giant beetle, at least five times more than five times the previous poisonous Gu, appeared, and spewed an incomparably amazing column of highly poisonous water towards Jia Zhengjin.

"Give it back to you!" Jia Zhengjin was not worried, and raised the Gaia Aegis again to resist.

Sure enough, the 70% reflection probability was very high, and the highly poisonous water column was also rebounded and fell back on the giant beetle.

However, it was not killed instantly, except that part of the carapace was cracked by the reflected magic, and other than that, it was unscathed. It roared angrily and began to spew out a continuous stream of highly poisonous water, hoping to kill Jia Zhengjin.

It's just that in front of the Aegis of Gaia, none of this means anything at all.

Jia Zhengjin patiently waited for it to be continuously attacked by the magic that rebounded back from him, seeing that there were more and more cracks on the giant beetle's body, and waited until it was bounced back and crumbling, before finally deciding to make a move, a flash stabbed over, directly penetrating the hard body of the giant beetle.

The trident enters through the rift and hits the other side out.

"Blah!!" The giant beetle struggled frantically, clearly uncomfortable being pierced by the trident. It's just that struggling is useless, and eventually he dies because of physical exhaustion.
