The left and right guardians took off the Peking Opera mask and showed their true face! However, Tang Fan and Tao Yueyao were shocked! The left guardian was nicknamed Heifenghu, and the skin on their face was pure black, while the right guardian was nicknamed Qingyunjiao, and the skin on their face was blue. No wonder they had such a nickname. Tang Fan probably understood something.

Suddenly, the left and right guardians used their rituals to burst their clothes, and all the clothes on their upper bodies retreated. Then, from the necks of the two of them, the black and blue on their skin began to spread towards their bodies. After a while, the left guardian turned into a muscular man with black all over the upper body, while the right guardian was blue.

"Oh my God...what monsters are they?" Tao Yueyao couldn't stop watching, obviously scared. She hurriedly looked at Tang Fan and asked.

"I don't know very well, maybe I'm a biochemical person..." Tang Fan said lightly.

"Hmph! You're really right!" Chen Xuanling snorted.

"Yes, it was the owner who gave us powerful strength! My body was injected with the 'green snake genetic modification agent'!" Chen Mingfeng said.

"My body is injected with the 'Black Cat Genetic Modifier'!" Chen Xuanling, who was standing beside him, echoed.

Tang Fan couldn't help but be surprised: Genetic modifier? Isn't this a thing invented by Dr. William? Why do they have it too? And they said it was given by Chang Wei. Could it be that Chang Wei and Dr. William have a cooperative relationship?

Recalling that Dragon Lion and Tiger and Chang Wei are adoptive fathers and Dr. William's experimental subjects, this further confirms the relationship between Chang Wei and Dr. William! And judging from the name of the genetically modified agent they injected, they should have obtained the ability of the green snake and the black cat, right?

Sure enough! Chen Xuanling's speed is as agile as a spirit cat, and at the same time it has a bit of a tiger-like momentum. It seems that this guy's ability has been upgraded! Tigers are also a kind of cat creatures, and cats can evolve into tigers when conditions permit.

"I said! You must die!" Chen Xuanling rushed towards Tang Fan.

Tang Fan used the shadowless stray bullet again, and still shook the opponent back. But at this moment, Chen Mingfeng jumped out from behind Chen Xuanling and then descended from the sky to attack Tang Fan!

Chen Mingfeng injected the "Green Snake Genetic Modifier", and his ability has also been upgraded. Just like his nickname, a green dragon that is more ferocious than the Green Snake! Chen Mingfeng's attack descended from the sky and headed towards Tang Fan's face.

Tang Fan felt slightly off guard, and he never expected that the cooperation between the left and right guardians would be so tacit! But even so, Tang Fan's danger warning had already made him realize that there was danger, and at the same time he had already turned on the visual enhancement of hsl serum.

When he saw that Chen Mingfeng was still in the air, Tang Fan had already picked up an iron pipe from the side. When Chen Mingfeng was descending, Tang Fan directly hit the other party's head with an iron pipe!

With a bang! Chen Mingfeng landed directly on the ground, then covered his head and screamed in pain. Seeing that the right protector suffered a loss, the left protector Chen Xuanling could rush forward! His right palm bent into claws and attacked Tang Fan directly at a black tiger with heart!

Seeing this scene, Tang Fan directly hit her with a stick! Chen Xuanling was hit by Tang Fan's stick!

"Hahaha, Brother Tang Fan, you are so awesome! The left and right guardians are not good people at first sight. I didn't expect you to defeat them so easily!" Tao Yueyao felt a little apart, and then laughed: "I rarely saw you take action before, but when I see you today... Puchi! It's really extraordinary!"

"If you have too much kung fu, no matter how good your kung fu is, you are afraid of making sticks!" Tang Fan shook the iron pipe in his hand and smiled faintly: "If I keep this stick, see if they dare to be arrogant!"

At this moment, the left and right guardians were depressed by Tang Fan's slap. They found that Tang Fan seemed to be able to predict his movements every time, and then attacked in advance to interrupt his attack.

"Boy! What kind of kung fu are you doing??" Chen Xuanling pointed at Tang Fan and shouted.

"My this? My this is not kung fu." Tang Fan said.

"You are playing tricks on us!" Chen Mingfeng was furious, and then turned into a dragon-like speed and suddenly attacked Tang Fan.

As a result, Tang Fan swept away with a stick, and at the same time, Chen Xuanling flew out. When the two of them got up and looked at each other for a moment, they realized that Tang Fan was not an ordinary person. If they didn't move, they would probably not be able to beat him.

"The owner of Changwei is kind to me! If the owner hadn't taken in us two brothers, there wouldn't be Chen Xuanling who I am today!" Chen Xuanling suddenly said in a tone that looked at death.

"That's right! I, Chen Mingfeng! Even if I stay here, I will let you go to hell with my secrets!" Chen Mingfeng said.

Seeing this, Tang Fan thought it was not good. It seemed that they knew Chang Wei's conspiracy early in the morning, and they were all in the same group. However, from their words and deeds, Tang Fan could hear that they were also loyal and righteous people, but unfortunately they followed the wrong master...

Suddenly, some strange changes began to occur in Chen Xuanling and Chen Mingfeng's heads. First, they rotated strangely twenty degrees clockwise, and then continued to rotate twenty degrees! Until their heads rotated a total of 180 degrees! Tao Yueyao closed her eyes. This was simply a scene in a horror movie!

But it was not over! After an unscientific twist on the heads of the left and right guardians, they finally fell to the ground...

Tang Fan was frightened again: No! Mutation! They must have been trying to forcefully upgrade the power of the genetically modified agent! But they failed... and caused mutation!

Chen Xuanling and Chen Mingfeng's bodies stood there frozen, and their heads had already fallen to the ground. Suddenly, a protruding sarcoma surged out of the spine of the two of them! The mutation speed was extremely fast! Finally, a black sarcoma bulged out from Chen Xuanling's spine, which looked like a faceless cat's head.

And Chen Mingfeng was the same, a snake-shaped sarcoma surged out of his spine. It seemed that the raised sarcoma behind these two men replaced their thoughts. This was a failed mutation. Tang Fan could see that not only did not enhance their abilities, but instead made their abilities even more wasteful!

They lost their sense of perception, smell, taste and vision! For Tang Fan, it was simply vulnerable! Soon, Tang Fan knocked these two guys unconscious! Then he found some ropes from the room to tie them up.

At the same time, Tang Fan led Tao Yueyao to continue moving downward. During the process of coming from the dark floor on the second floor to the dark floor on the first floor, Tang Fan discovered many signs of life. After entering the room on the dark floor on the first floor, he found that there was a cage inside, and many people were imprisoned inside!

"Kou Qing Bronze!?" Tang Fan discovered the person he was looking for from this group of people.

"Tang Fan! That's great! You finally came to save us!" Seeing Tang Fan's appearance, Kou Qingtong rushed to the cage out of joy, and at the same time, the people who were detained behind him also came over.
