Turning back the timeline a little, that is, three days before Shen Fangli lost all her memories, an inconspicuous incident happened somewhere on Glaze Island, and no one thought that this incident would be the prelude to the entire Glaze Island disaster.

There is a scientific research laboratory on Jialian Mountain, the highest peak to the west of Glaze Island, which was built to develop new products, and of course, this scientific research laboratory has another purpose, which is to develop new weapons for the Glaze Island Wai people.

Glaze Island belongs to the Principality of Vulken established by the Wei people, the country implements the patriarch system, and the four patriarchs vote to elect representatives to exercise the highest administrative power, since Mo Ran became the patriarch of Glaze Island, the other three patriarchs voted for the patriarch of the island on the grounds of lack of experience, which made Mo Ran very annoyed, because the new patriarch of the island is a mediocre and ignorant person, for his own pleasure, wantonly exploiting the financial income of the remaining three islands. But even so, the other three patriarchs still didn't want Mo Ran to be in power, on the grounds that Mo Ran was too smart and would definitely threaten their vested interests after taking office.

More importantly, Mo Ran is a thorough reformer, he unscrupulously seized the power of Glaze Island in order to completely change the system of the Wei clan, he learned a lot of knowledge about the Middle-earth system from his master Tong Coat a long time ago, in his opinion, the liberal and democratic system promoted the development of science and technology, which created such a powerful country, compared to the Duchy of Vulcan, the real power is in the hands of the hereditary patriarch, if it is allowed to develop, the country will definitely perish, and the only way is to launch a war against the remaining three islands.

However, waging war requires a lot of money to develop weapons, and among the four major islands, Glaze Island has the weakest military strength, and it is impossible to catch up with the other party in the short term, and needs a weapon that can immediately establish a victory once used, so Mo Ran established the Jialian Scientific Research Office, with his most trusted Yu Caiyi as the director.

Speaking of this Yu Caiyi, his background is really not small, he was the director of the first hospital on Qidao, the second black spot plague crisis was controlled by virtue of the special medicine he developed, this person is not only skilled in medicine, but also highly cultivated, once participated in the arrest of Shen Fangli, after Mo Ran took power, he was rewarded for meritorious deeds, and he was promoted first. His prominent social status made him distracted from his interest in practicing medicine, and it didn't take long for him to resign from his position as dean and come to the Jialian Mountain Scientific Research Laboratory to concentrate on researching new weapons for Mo Ran.

In order to block the news, Mo Ran ordered the area around Jialian Mountain to be listed as a military restricted area, and ordinary people were not allowed to enter without permission, he thought that he could do it in this way, but he greatly underestimated the intelligence ability of the Tianzhao Sect.

Since devoting himself to scientific research, he has fallen into a hysterical frenzy, and the experiments have been accompanied by numerous failures, but each failure is sweeter than the development of a new drug. He successfully extracted the black spot pathogen from the cat's monster, and through years of research, he found that this virus has a strong adaptability, and every time it is killed by the black spot disease special drug solution, a very small number of viruses will survive, and the posterior bands of these small viruses will have drug resistance. So he increased the pill one by one, and when the new HBZY-2 drug was applied to the virus by ten times, the virus all died, and it seemed that this was the limit of the mutation of the black spot virus.

Unfortunately, research has hit a bottleneck. But Yu Caiyi did not give up, if the highly virulent black spot virus can be produced, this will be the world's first biological weapon, if it can be used in war, the Wei clan will be invincible.

He also made tons of mixed solutions of the UV virus in a large aluminum alloy container that was as large as the ceiling.

Until that day, a fortuitous event led to the birth of that deadly poison gas.

As usual, that day Yu Caiyi stayed alone in the laboratory and flipped through the experimental records, before this he had been working for more than ten hours in a row, and the fatigue soon hit, but he still insisted on reading all the materials, and then he observed the test subjects, in the test room, there were dozens of small monsters captured by Yu Caiyi around the world, each of which was locked in a sealed iron cage, and he controlled the buttons in front of the screen, releasing the sample poison gas, and observing the poisoning symptoms of the monsters one by one. The lever on the manipulator also controls the addition of various chemical gases, and when the test is not ideal, he appropriately adds a certain chemical gas.

The sleepy-eyed fluffy Yu Caiyi mislooked at the lever on the instrument, and added poison killing gas to the No. 5 test cage, which is a chemical gas that can quickly kill pathogens, and when he reflected it, he felt that something was wrong, but unfortunately it was too late, the poisonicidal gas fused with the black spot virus gas in the No. 5 test cage, and when he had a premonition that the test was going to fail, a miracle happened, and five minutes later, the cat in the No. 5 test cage had convulsions, foaming at the mouth, and died not long after.

You must know that the cat monster is the carrier of the black spot pathogen, itself is immune to the black spot virus, if you want to poison the cat monster, this gas is at least hundreds of times more virulent than the black spot virus, it is certain that in the fifth test cage, the black spot virus gas has undergone a new mutation under the effect of killing gas, and has evolved into a new virus.

"I succeeded, I finally succeeded. He quickly collected the mixed poisonous gases, recorded the symptoms caused by the poisonous gases through several experiments, and then inferred the symptoms of the symptoms on the human body from the syndrome exhibited by the demonic beasts.

It has been calculated that if this mixed poisonous gas is inhaled by the human body, the symptoms of convulsions and hematemesis will occur, and the symptoms of hematemesis can continue until the death of the patient, and the skin will be purple-black after death, with some characteristics of the original black spot disease that caused the death. She Caiyi named this poison gas Black Death Poison Gas and separated the samples.

Fortunately, the poisonicidal gas is easily soluble in the mixed solution of the UV black spot virus, and it is not a problem to produce large quantities of black death gas. It is only necessary to study the launcher. She Caiyi immediately informed Mo Ran of the test results and invited the other party to inspect his laboratory in person.

Mo Ran, who learned the news, took two bodyguards to the Jialian Mountain Scientific Research Laboratory, and Yu Caiyi repeated the test process with them, and explained in detail the toxicity of the Black Death Poison Gas, he took Mo Ran to visit the huge aluminum alloy container containing the Black Death Solution, and discussed with Mo Ran his own ideas for the future use of this poison gas.

Mo Ran touched his beard, nodded while listening, and praised: "Very good job, with this poisonous gas, the other coalition forces of the three islands together are not the opponents of our army." ”

Seeing that Mo Ran was so satisfied, Yu Caiyi looked very proud: "Isn't it, the Black Death Gas can be regarded as the biggest masterpiece in my life." ”

Mo Ran frowned and smiled: "What kind of reward do you want, just say it, you have contributed a lot to the research of the Black Death Poison Gas this time." ”

"Well...... "Yu Caiyi scratched his head embarrassedly.

His ugliness angered the male bodyguard next to Mo Ran, this person is named Sha Yu, who was originally a police officer in the police station in Qidao City, he thought that he could be promoted by betraying the police station and joining Mo Ran, but he was not satisfied with his position, in his opinion, Yu Caiyi was just a guy who was good at patting on the back, why did he get Mo Ran's favor.

"To be honest, I don't dare to compliment you on the poison gas you developed, any very toxic argument is the result of your experiments on demonic beasts. Sha Yu sneered, "How can it be proved that it is also very toxic to people? Moreover, the black death gas has lost its infectivity compared to the black spot virus, so it is impossible to achieve large-scale killing." ”

"Oh, do you want to test the poison of the Black Death?"

"No...... No...... I'm just talking about it...... Hehe...... "Shaved Eagle retreated again and again with a smile on his face.

"Patriarch, Shaved Duck is right, the Black Death poison gas that has not been tested on humans really cannot prove its toxicity, since Shaved Owl volunteered to act as a tester, why don't we give it a try?"

She Caiyi said and took out the sealed black death solution test tube from his coat pocket, and signaled to Mo Ran with his eyes, Mo Ran understood what he meant, and took out a short staff and hit the shaving eagle is a fixing spell, making the shaving bird unable to move, and could only watch as She Caiyi gradually approached him.

"Patriarch, spare your life......" Shaved Duck cried like a pig, but Mo Ran was indifferent at all, until Yu Caiyi broke his mouth open and poured the black death solution into his mouth.

Five minutes later, the effect was there, and the shaved owl fell to the ground and twitched like a reptile, and then he began to vomit desperately, until he vomited a large amount of blood, and suddenly his eyes rolled and he lost his breath, and finally his skin gradually turned black and purple.

"Oh! it was perfect, the black death solution took less time to kill people than expected, only ten minutes or so. She Caiyi glanced at the wall clock on the wall, "If it's gas, I'm afraid this time will be greatly shortened." ”

"The Black Death gas is powerful, but aren't you too optimistic? ”

"What do you mean, Incense? Dare to question my invention. Yu Caiyi glanced at the female bodyguard beside Mo Ran with an angry face, the woman's name was Xiangxiang, Mo Ran was Shen Fangli's maid before the coup, but because she had not done much in the past few years, Yu Caiyi didn't take her seriously at all.

"I don't question your invention, but I just want to remind you that any invention is a 'double-edged sword'. She closed her eyes with her feet for the dead shaved eagle, and then turned to the huge container containing the black death solution, "Have you ever thought that if the black death solution in this part leaks out, the gray smoke formed by the black death gas will spread throughout the glaze island, and no one will survive on the glaze island?" ”

"This ......"

As soon as Yu Caiyi wanted to argue, Mo Ran stretched out his hand to stop it: "In short, you must keep it a secret, if something goes wrong, I won't let you go, understand?"

Seeing Yu Caiyi's vigorous nod, Mo Ran finally felt relieved and left the Jialian Mountain Scientific Research Laboratory with Yanxiang.

At this time, no one noticed that in a corner of the laboratory, a strange puddle of water was converging and forming, gradually turning into a human form, and this person was Brilliant Blue.
