Lu Jiajun returned to the Tianyue base under the leadership of Huo Yading, and went back with a large number of scientific research equipment, which was arranged by Lin Xiaoxiao.

Shi Hongji and Hu Zhenlong, two chemists, seemed to usher in a second spring and immediately devoted themselves to research work.

Lu Fan returned to the third floor of the Scientific Research Building, put the Red Flame Halberd back, and then cautiously sneaked down the sewer.

The city is mountainous, and only the southern suburbs are considered plains, and it has suffered many floods, and the government has helped the southern suburbs to build a perfect drainage system, and since then it has become a paradise.

Lu Fan took out a high-power searchlight from the storage space and illuminated the pitch-black sewer.

The inside was very wide, at least Lu Fan had no problem standing and walking, he kept walking along the sewers, and gradually explored the past into the depths.

"Tick, tick!"

The sewers are filled with dripping sounds, which are seeping water from the soil layers, and all of it is drained through the sewers.

The sewers are winding and deep, and it is pitch black and I don't know where it leads?

The appearance of zombies is a normal thing, but there must be a reason for the inexplicable zombie gathering, especially in this dark and damp sewer, it is incredible to be able to gather so many zombies.

The zombies have no intelligence, they act purely on instinct, and they all go into the sewers, indicating that there is something amazing here.

The terrain is getting lower and lower, and many places are beginning to have hoarded water stains, which are filled with zombie blood, and under the light, they look particularly dull.

Suddenly, a strong stench came, which made Lu Fan frown.

"Something, it stinks so much, it stinks even more than the carrion of zombies!"

Lu Fan muttered in his heart, but his eyes became sharper and sharper, he knew that the appearance of such an abnormal situation was very likely to find the truth of the matter.

Continuing along the passage, the stench grew stronger and stronger, until after turning a few corners, Lu Fan found that the space in front of him had become more open.

"What is this?"

There are rubble scattered everywhere around, and the sewers, which were originally neatly repaired, have been destroyed and messy, like rat holes, and have been enlarged a lot.

Lu Fan picked up the stones and clods scattered around him, and after carefully identifying them, he determined that the space here had just been dug up, and many of the stones and clods had obviously just been dug up.

Lu Fan carefully observed the situation here and found that there was no carrion of ordinary zombies here, and it didn't look like a place where ordinary zombies had stayed, as if it was a forbidden area for ordinary zombies, which had a completely different appearance from the passage outside.

Could it be that this place is occupied by that second-order zombie, and ordinary zombies don't dare to take a step beyond the thunder pool?

Lu Fan guessed in his heart that he walked towards the central area of this vast space, hoping to find the source of the stench first.

The high-power strong light searchlight kept shooting, Lu Fan walked cautiously, in this unfamiliar space, Rao is he has a strong combat power, and he can't help but feel furious in his heart.

"What is this?"

Suddenly, Lu Fan found a pitch-black waterhole in the center of the area, and in the center of the waterhole, a black-covered plant was growing.

"Is it a lotus?"

The leaves floating on the black pool look very much like lotus leaves in a pond, and the flower bones standing above the black water are a budding lotus flower.

"Gollum, Gollum!"

At this moment, Lu Fan noticed that a black stream of water appeared under his feet, and the strong rancid smell was extremely pungent.

This is black dirty blood, just now by Lu Jiajun killed 20,000 zombies, the blood flowed, and now it is gathered here through the drainage system, making the black waterhole a lot bigger.

At this moment, Lu Fan finally understood what the black pool was, it turned out to be a large amount of zombie blood, no wonder it emitted such a strong rancid smell.

"Why do zombies surround this black lotus?"

Lu Fan was puzzled, too many questions were circling in his mind, such as the black spar on Tianlong Mountain, the black lotus here, why did it attract zombies?

Soon, Lu Fan discovered the difference between the black lotus and the black crystal.

At the beginning of Tianlong Mountain, the zombie group violently impacted the mountain, swallowing the black crystals that appeared into his abdomen, and the terrifying scene that he couldn't wait for was still fresh in Lu Fan's memory.

And the scene in front of him looked more like a second-order zombie guarding this place, not only did he not snatch the black lotus, but he also restricted ordinary zombies to this area.

It looks more like protecting this black lotus.

"What secrets are hidden in this black lotus? Why do second-order zombies protect it? ”

Lu Fan was puzzled, he took out the Red Flame Battle Halberd with a snort, preparing to destroy this black lotus here, most of the things that zombies like are unfavorable to human beings.

"Boom!"

The Red Flame Battle Halberd erupted with blazing light, illuminating the entire dark space in an instant, and with a bang, the powerful power of the third-order evolutionary slashed at the Black Lotus.

"Bell!"

There was a sound of metal impact, and the huge Red Flame War Halberd was unexpectedly rebounded, and due to the excessive force, Lu Fan's tiger mouth was shocked and almost cracked.

"Damn, what's the situation!"

Lu Fan looked at the black lotus in front of him dumbfounded, and couldn't help but burst into a foul mouth.

Lu Fan knew how much power he used just now, and he was afraid that there was a second-order zombie blocking the front, and it had been split in half at this time, and this black lotus was unexpectedly intact.

Lu Fan couldn't help but shrink his pupils, the more extraordinary this black lotus was, the more bottomless his heart became.

Just a black lotus, Lu Fan couldn't destroy it, this kind of thing spread out is unbelievable.

"I don't believe in evil yet, a dignified third-order evolutionary, can't destroy a plant?"

Lu Fan took two steps back, and the strong momentum of the third-order evolutionary exploded, and then blessed his speed enhancement and released his strongest blow at present.

"Humph!"

Lu Fan roared angrily, and the Red Flame Halberd suddenly burst into flames, and an incomparable terrifying aura rose into the sky, as if a storm was blowing in the entire drainage system, and the ground was full of the sound of air jets.

"Bell!"

There was another metal crash, and the Red Flame Halberd once again collided with the black lotus, but the lotus only trembled slightly, and then stood up again, without the slightest damage to its appearance.

"What the hell!"

Lu Fan was completely speechless, and at this moment he finally understood, it wasn't that the second-order zombie didn't want to eat this lotus, I'm afraid he couldn't bite it.

Lu Fan suddenly had a trace of curiosity, and secretly said in his heart: "This black lotus is so extraordinary, if it blooms, will there be unexpected benefits?" ”

Lu Fan was shocked in his heart, and suddenly became deeply curious about this black lotus.
