At the same time, Professor Li Sanming's assistant also moved. A flying insect bit his neck. He growled, stretched out his right hand and patted him on the neck.

Almost at the same time, the two frogs rushed towards the assistant of the Gem Davao Khan and Professor Li Sanming, "Ah!"

Professor Li Sanming's assistant could not dodge and was hit by a frog on the back of his hand. Davao Khan was sensitive and although he was scared, the grenade in his hand was thrown out before he fell to the ground.

"Everyone is lying down!" Booktonlin issued an instruction, and everyone fell to the ground. The reaction was slower. Seeing that everyone else had fallen to the ground, they also followed suit and fell down.

There was a loud "bang", grass chips and soil, mixed with some frog limbs, flying all over the sky, splashing on the members of the scientific expedition team and the Black Mamba Guard.

The frogs' screams suddenly became much smaller, and the remaining frogs all rang from near to far, and the frogs surrounding them fled in scattered.

"Ah...ah...ah..." Professor Li Sanming's assistant sank on the ground in pain, and white foam oozed out of his mouth. Professor Li Sanming stepped forward and saw that the assistant was holding his wrist in great pain. The hand that was hit by the frog was swollen, and there was a thin pinhole-like wound on the back of his hand, oozing blood. The blood vessels near the wound were blue, surrounding the wound like black spider webs.

Lima Oda happened to be near Professor Li Sanming. She saw the injuries of Professor Li Sanming's assistant and immediately crawled over. She looked at the wound with a terrified face, and said in a trembling voice: "This is the poison of the arrow frog!"

"What?" Professor Li Sanming was so nervous that he hurriedly shouted to Nandegrad, "Medical officer, come here quickly, someone has been poisoned!"

Nandegrad was close to the place where the grenade exploded, and his ears were a little inaudible. It was not until Professor Li Sanming called him many times that he could hear clearly, and he staggered from the ground and ran towards Professor Li Sanming.

When he saw Professor Li Sanming's assistant's miserable appearance, he shook his head and said, "I'm afraid there is no saving."

"Please give him serum and detoxify." Professor Li Sanming roared at Nandegrad almost angrily.

"Professor, be calm, it's not that I don't save you, it's really... I can't save you anymore." Nandegrad lowered his head. It's not that he couldn't do medical skills. He was really tired of facing such symptoms.

Everyone around looked at Professor Li Sanming's assistant again. His whole body was twitching and foaming at his mouth. The poisoned hand was already blue and his arms were curled up in front of his chest, like a chicken's feet dry and weak.

Professor Li Sanming watched his assistant twitch for about ten seconds and no longer moved.

"Zi Ji, I told you not to follow me, you have to follow me, now, how can you tell me to explain to your parents..." Professor Li Sanming's voice was sad. He hugged his assistant's body and burst into tears. Although he did not cry out loud, the huge sadness moved everyone present.

Professor Li Sanming's assistant was his most proud disciple. He had hope of replacing his status, but the master and apprentice entered the Bloss disc together. After experiencing ups and downs, there was no problem. Unexpectedly, the first team member to have an accident in New Bloss was this assistant.

"What kind of poison is this?" Booktonlin asked Nandegrad, who was standing aside and silently.

"It looks a bit like snake venom." Nandegrad analyzed, "Snake venom is divided into neurotoxins and hemolytic toxins. Bites such as vipers, abdominal snakes, bamboo leaf greens, and five-step snakes are hemolytic toxins, causing the bitten area to swell quickly, harden, bleeding, severe pain, purple-black skin, skin necrosis and enlarged lymph nodes. It can spread to the head, neck, limbs and waist and back for 6-8 hours. The injured person trembles, body temperature rises, cardiac movements accelerate, difficulty breathing, and cannot stand. Nose bleeding, hematuria, and convulsions. If the bite is not effectively treated within 4 hours, he will eventually die of heart failure or shock."

Nandegrad bent down and pointed at Professor Li Sanming's assistant's swollen palm, "Look at his hands, it's like the damage caused by hemolytic toxins."

Nandegrad pointed to the foam on his assistant's mouth and said, "But this symptom is like a neurotoxin. The toxin secreted by snakes such as the golden ring snake and the silver ring snake is neurotoxin. After the bite, the local symptoms are not obvious, there is less bleeding, and the redness, swelling and fever are mild. However, there are rapid systemic symptoms within a few hours after the injury. The patient is excited and moans in pain, trembling all over the body, foaming, difficulty swallowing, difficulty breathing, and finally lying on the ground, twitching throughout the body, paralyzing the respiratory muscles and dying."

Nandegrad stood up and said with his waist on his back: "Overall, this is a bit like the symptoms caused by the mixed toxins in snake venom. The local wounds are red, swollen, fever, pain, and may have necrosis. After the toxin is absorbed, the systemic symptoms are serious and complex, with both neurological symptoms and damage caused by blood circulation toxins. In the end, they all died of asphyxiation or heart failure."

Nandegrad touched his chin again, tilted his head and said in confusion: "But only cobras can secrete mixed snake venom. Have you seen cobras?"

"This is not snake venom, this is arrow frog poison." Oda Lima said firmly.

"Drowning Frog?" Booktonlin frowned and looked at Lima Oda. As a former mercenary who roamed Hallelujah, he naturally had heard of the famous name of the Drowning Frog.

"Yes, it's the arrow frog." Oda Lima was determined.

"Why are you so sure?" Booktonlin only saw one or two arrow frogs in the tropical rainforest. This is the first time he has seen such a large group of arrow frogs, and it is also the first time he has seen arrow frogs hurt people.

"It's very simple, the snake venom does not occur so quickly." Oda Lima looked at Nandegrad, "It will take at least a few hours for snake venom to kill people, and it will not cause death so quickly."

Nandegrad's eyes met Lima Oda and then dimmed. Indeed, snake venom was not as fast as to kill people, and it was impossible for snakes to be poisoned.

"That can only be ruled out that it is not snake venom," Nandegrad hugged his hands in front of his chest. "In addition to snake venom, some lizards can also secrete similar toxins."

"But we all heard it just now, and the frogs surrounded us." Bridgemorgen walked up and spoke for Oda Lima.

"Didn't the frog be blown away by us?" Blaster Davao Khan stood on the side of Nandegrad.

"Look at this, everyone," Lima Oda squatted down next to Professor Li Sanming's assistant and pointed to the wound on his assistant's hand. "His poisoning was obviously spread from this wound, spreading from this point to the surroundings of his body, and eventually led to his heart failure and respiratory failure, so he died in a short period of time."

The small mouth on the assistant's hand was just a small dot, but against the backdrop of the dense black spider-web-like nerve veins around it, it was obvious that the toxins were spreading from here.

"And this wound was caused by a needle prick on the head of the arrow frog." Oda Lima stood up. "When the arrow frog saw an enemy whose size was larger than that of it, it would use the needle prick on the other party's body to release toxins and cause the other party to die."

"But is the toxin of the arrow frog so powerful?" Booktonlin doubted, "Even the toxin of the cobra can't kill people so quickly. A small arrow frog is so poisonous?"

"Captain!" sniper Wu Yongqiang shouted while running, holding something in his hand, "I picked up a frog's body!"

Wu Yongqiang ran to Booktonlin and handed over the things in his hand.

Booktonlin took it and saw that it was a strange frog corpse, with only his head and body left, and the two legs and part of his lower body were blown away.

Booktonlin handed the frog's body to Lima Oda. Lima Oda took it over and over and over and over, and finally concluded: "This is the arrow frog. This kind of arrow frog is called the Green Demon Arrow Frog. It is green all over and is hidden in the grass and is difficult to find. However, once it attacks the enemy, it is a fatal blow, so it is called the Green Demon. There are all kinds of animals living in the jungle that are not afraid of it."

"How did it attack the enemy?" Pang Xiaonan was very interested in the animal world. It was amazing that this little frog could actually kill an adult in a very short time.

"They live in dense forests, with thorns on their faces, and can be injected with toxins by hitting their heads. The pain caused by their venom is strong and long-lasting. One gram of venom from this poisonous frog is enough to kill 300,000 mice or 80 adults." The data Oda Lima said was impressive and everyone was shuddering.

"In ancient times, primitive people used the venom of the Green Demon Arrow Frog to make poisonous arrows to hunt prey." Oda Lima added, "But many primitive people died in the process of catching the Green Demon Arrow Frog."

"Oh my God, what kind of world do we have in?" Professor Niuphras shouted to the sky with some despair. He was just a physicist and had never seen the cruelty of nature.

"Don't panic, everyone," Booktonlin tried hard to calm everyone's emotions. He knew that if this continued, the scientific expedition team was killed by any beast.
