Online game: Thunder Tyrant, I have infinite critical hits!

The rain poured down like a waterfall, engulfing the world in an instant.

Jiang Yan and his three companions stood on the back of the giant dragon, looking down at the swamp covered by pale yellow rainwater.

"Old Zhao, thank goodness we had you, otherwise we would never have been able to complete this mission," Good Luck said with emotion.

As the only person present who had personally experienced speeding through the sulfuric acid rain, Good Luck knew best how terrible the rain was: the powerful corrosiveness, the high cost of poisoning, and the disorientation caused by having one's vision clouded by the rain, making it impossible to distinguish east from west!

Without Zhao Shanshan, their entire group would most likely have been wiped out!

Splash splash splash...

Pale yellow rain obscured the sky and the sun, pounding against the milky white shield on the dragon's body like machine gun fire.

Simultaneously, a series of damage numbers popped up above Zhao Shanshan's head. While taking pills, he quickly said, "Godfather, give me some more pills!"

After a round of upgrades, the dragon's size has surpassed that of the Sky-Splitting Wind Eagle, so Zhao Shanshan's shield also had to be enlarged. However, this also meant that the shield was subjected to more rain impacts!

Zhao Shanshan's supply of elixirs was already running low.

Upon hearing this, Jiang Yan immediately initiated a trade with Zhao Shanshan, giving him five hundred high-grade blood pills. (High-grade blood pill: Restores 15% health per second for 5 seconds!)

These five hundred high-grade blood pills are enough to sustain him for forty minutes!

So next... Jiang Yan turned to Lei Hu: "Lei Hu, let's continue."

"Ah, aren't we going to wait until the sulfuric acid rain stops?" Lei Hu was taken aback.

"Acid rain is a problem for us, and for the monsters in the swamp too," Jiang Yan laughed. "We can take advantage of this rain to venture deeper into the swamp and search for Felix!"

"Brother Jiang is right. As long as Lao Zhao can hold on, this rain will be a good thing for us!" Good Luck said.

"Alright." Lei Hu glanced at Zhao Shanshan and immediately ordered the giant dragon to fly towards the depths of the swamp.

At this point, the dragon's size was comparable to that of an elephant, with a wingspan of over forty meters. Its pale red scales were as fierce as iron, gleaming with a chilling metallic luster. Even its roar had become more authentic and was no longer immature.

Lei Hu named it "Red Dragon"!

"Red Dragon, let's charge!" Lei Hu stood on the back of the Red Dragon, raising his golden greatsword high, looking quite like a dragon knight.

"Roar!!" The red dragon roared and flapped its wings, quickly weaving through the sulfuric acid rain.

As they ventured deeper into the swamp, Jiang Yan and his group indeed encountered no more monsters. The sulfuric acid rain had forcibly suppressed all the monsters in the swamp deep into the mud!

Of course, there are exceptions!

"Roar!!" From the depths of the swamp, a roar that was neither dragon nor tiger suddenly came, vibrating violently in the sulfuric acid rain.

Another giant tree, hundreds of meters tall, was uprooted in the sulfuric acid rain, waving hundreds and thousands of branches to hunt and devour wild monsters in the mud!

"Damn, all sorts of monsters and demons come out when this sulfuric acid rain comes down!" Lei Hu stared wide-eyed at the giant tree.

The next instant, the giant tree seemed to have spotted the dragon. It turned around, and countless branches shot straight up into the sky!

"Red Dragon, fly higher!!" Lei Hu quickly ordered.

"Roar!" The red dragon roared and hurriedly flapped its wings to fly high, avoiding the branches of the giant tree.

However, at that moment, a sudden gust of wind swept in from high above. When everyone looked up, they saw a vulture with a rotting body and countless chilling white bones swooping down, its claws showing bare bones, viciously grabbing at the red dragon!

Decaying Vulture King (Dark Gold BOSS): Possesses powerful dual defenses.

grade:……

Health Points: …………

"A Dark Gold BOSS dares to show its face?" Jiang Yan sneered and immediately brandished his staff: "Thunder Dragon!"

"Roar!" The thunder dragon roared and flew, crashing headfirst into the decaying eagle demon king, triggering a violent thunderstorm!

-213300

-231504

Amidst the crimson critical damage, the Decaying Vulture King let out a strange cry and fled in panic, flapping its wings.

"Let's keep going!" Jiang Yan didn't press his advantage. The mission was the priority. Otherwise, who knew what kind of weird monsters might appear after the rain stopped?

After regaining its balance, the red dragon continued to flap its wings and move forward.

After venturing deeper into the swamp, the group encountered seven or eight more unique bosses that could move freely in the acid rain, but unfortunately, none of them were Felix!

Half an hour passed in the blink of an eye. The sulfuric acid rain in the sky gradually thinned out, and countless wild monsters hidden under the swamp mud broke out of the mud, unleashing their powerful auras without restraint.

Jiang Yan speculated that the average level of the monsters here was likely over one hundred!

"Boss Jiang, we should retreat," Good Luck reminded us in a low voice. "The monsters down there seem to have their eyes on us!"

"Roar!" The red dragon echoed the sentiment and roared incessantly.

Lei Hu also said, "Godfather, should we retreat first? Chi Long seems afraid."

Jiang Yan nodded helplessly: "Then let's retreat for now. We'll come back in when the next sulfuric acid rain comes."

The red dragon cheered and immediately turned and flew wildly away!

For the next day, whenever it rained, Jiang Yan and his three companions would fly into the depths of the swamp to search for Felix, and as soon as the rain stopped, they would immediately retreat.

Unfortunately, after searching for a whole day and night, there was still no trace of Felix!

"This can't go on!" Jiang Yan's expression was grave. The pills in his backpack were only enough to last for three or four more sulfuric acid rains at most. Once the pills ran out, they would have no choice but to use the [Return Scroll] to leave this place!

We can't just go back empty-handed from a high-level dungeon, can we?

Jiang Yan frowned and pondered, trying to figure out where the problem lay.

"Why don't we ask Little East Evil?" Good Luck suggested.

"I'll come!" Lei Hu immediately sent a private message. A moment later, Lei Hu's expression turned strange as he said, "Little East Evil said he found a mass grave under the ancient building complex, filled with bones; at least several thousand people died!"

"Why does he always like to run underground?" Zhao Shanshan complained.

Lei Hu's expression grew increasingly strange: "He burrowed underground precisely because he couldn't find it up there."

"Didn't he find them up there?" Jiang Yan was taken aback. "Didn't he go check over at the fire pit? There are still hundreds of ancient people there!"

Lei Hu shook his head: "Xiao Dongxie said that he didn't find any traces of ancient people up there, and suspected that they had all taken shelter underground from the rain. As a result, he discovered the mass grave."

"How is that possible?" Jiang Yan was stunned. He had personally witnessed hundreds of ancient people kneeling and worshipping the divine fire by the fire pit. How could Little East Evil not have noticed a single one?

"Brother Jiang, since we haven't found anything here, why don't we go back and take a look?" Good Luck asked in a low voice. He suspected that Jiang Yan might have made a mistake, but he didn't want to say it directly.

"Alright." Jiang Yan nodded. They had searched here all day and found nothing, so they might as well go back and check. If there really was a problem... Jiang Yan's expression gradually became serious.

Afterwards, Zhao Shanshan and Haoyunlai rode Lei Hu's Crimson Dragon back together, while Jiang Yan rode the Sky-Splitting Wind Eagle and rushed back alone first!
