The letter was sent to Wu Jun, Jiang Qin and Zhou Tai asked their literate lieutenants to read the letter, Jiang Qin smiled, "When did a Vermilion Bird Marquis come out on the ground in Jingzhou, I think you are pretending to be a clan, and the crime will be increased by one degree, and we will enforce the law for the Son of Heaven." ”

Pull the banner when the tiger skin can not bluff the veteran oil, this trick does not work, the Eastern Wu army is ready to attack the city, but the second general sees the city head flag covering the sky and the sun, the city guards are longing, the voices are boiling, a well-prepared look, the heart is worried, dare not do it, is hesitating, the spies report, a boat came out of the West Water Gate, and it also rushed upstream.

"It must have been a tip. ”

Zhou Tai laughed and said, "They must have dragged the people in the city to the city, and they are a useless strategy." ”

Su Yu made a mistake, she sent a clipper to inform Liu Yuan, but it turned out that Jiang Erjiang saw the truth, and the second general decided to attack the city immediately.

The siege began from the water gate, three warships rushed to the East Water Gate with an angle of attack and a crash, before they hit the city gate, a black thing fell from the sky and fell on the warship, the Dongwu sergeant looked at it, it was a white smoke thing, round and rolled into the cabin, just wondering, a loud noise, the warship exploded, the two warships next to it were affected, and they were also blown into powder at the same time, and the entire Dongwu army was shaken.

Jiang Qin Zhoutai had only heard of water warfare and fire attacks, and had never seen such a powerful explosion, and he thought that the Omi Warlock could lead the thunder down from the sky, so he was so frightened that the two trembled, and he was unstable on his feet.

Su Yu appeared at the head of the city and shouted loudly: "Jiang Qin, Zhou Tai, two generals, Suzaku has the help of immortals, can lead the thunder of the sky, if you don't want to be punished by heaven, please leave quickly." ”

Seeing that the three warships were destroyed by a thunderbolt, and the general who defended the city was actually a woman, and the things on his body were strangely shaped, not like armor, and it was more confirmed that Suzaku had a strange person to help him, the Eastern Wu army was frightened, and there was no will to fight, Jiang Qin and Zhou Tai did not dare to enter the army, nor did they dare to withdraw the army without authorization, and sent someone to fly the clipper to report to Zhou Yu.

Su Yu saw that the Wu army stopped attacking the city, so she breathed a sigh of relief, she relied on the wisdom to win or the wisdom of the two thousand years ahead, a defensive grenade, they crossed this time with the intention of changing the course of history, naturally it is impossible to make black and gunpowder from scratch, in addition to the weapon firepower equipped on the mecha, the traversal cabin is almost arranged as an arsenal, all kinds of modern weapons and ammunition are available, if the Wu army attacks the city again, Su Yu even plans to take out the grenade launcher.

Gunpowder was first made by alchemists in the Tang Dynasty, and high-energy explosives were not invented until the Nobel Prize in the 19th century.

It's a pity that Su Yu met two reckless men who lacked brains, if they were suspicious, they must have really retreated, but Jiang Qin Zhou Tai was born as a homeless person, and he didn't study, and his brain was simple, although he temporarily stopped attacking and went to report to the governor, but his mind was simple, thinking that the thunder was a god in the sky, and he had to ask the thunder mother to show it, and it was inconvenient to invite God at night, so it was better to take the opportunity to launch a night attack.

So, they ordered the Eastern Wu army to pretend to retreat, but they unloaded the foot soldiers ten miles downstream, secretly attacked by land, and quietly came to the Suzaku City on the third watch day, erected a cloud ladder to attack the city.

During the day, Su Yu let the new army wave the flag and shout, at night it was the old army guarding the city, the old army was still vigilant, and when he saw the Wu army sneaking in, he immediately sounded the gong to warn, which avoided the danger of the city breaking, and the shouts shook the sky for a while, and the torches at the head of the city were as bright as day, Su Yu got the news, put on the mecha and went straight to the city gate.

The Wu army attacked from the south gate, the Jianrui battalion had climbed the city wall, and was fighting a bloody battle with the defenders, although the number of defenders was nearly half more than the attacker, but to defend 4 city walls, plus more than 2,000 new troops who slept a lot, the allocation to the south gate was actually only a few hundred people, and the Wu army's superior forces were defeated and retreated.

Su Yu flew to the sky above the city wall and found that he could not use heat and weapons to support, because the two sides were entangled, and the dogs and teeth were staggered, and he would definitely hurt his own people when he opened fire, so he fell to the wall in a hurry.

A Wu army swung a knife and slashed, Su Yu swung it out, and immediately slapped this soldier like a fly and fell off the city, Su Yu had an idea and flicked away the long sword.

Su Yu's tall figure is close to one meter eight, and he still maintains the habit of fitness after getting married and having children, his limbs are well-proportioned and advantageous, and he is tall and flexible, and those Dongwu water soldiers are all indigenous people in the south, they are short, and the military food on weekdays is just porridge and pickles, and they can only occasionally have one or two meals of wine and meat when they fight, and nine out of ten are malnourished, not only have little strength, but their night vision is also very poor because of the lack of vitamin A.

In the face of this group of soldiers with an average height of about one meter six, Su Yu is simply a giant spirit god-like existence, although she has not systematically learned martial arts, but with the invulnerable mecha, she is like a hanging, raising her sword and slashing indiscriminately, a set of Wang Ba sword techniques down, chopping melons and cutting vegetables will kill all the Wu troops who rushed to the city in the first wave.

Blood flowed all over the ground, walking was slippery, dead bodies were everywhere, Su Yu stood alone under the moonlight, majestic and majestic, with great picture impact.

The defenders at the head of the wall were already on the verge of collapse, and seeing that although the Duchess of their own family was a woman, they were the first to take the lead, and they were so brave and brave in a bloody battle, and their morale was greatly boosted for a while, and they shouted and rushed up again, and they actually drove back the Wu army that had attacked the city.

Looking at the dense Wu army under the city, Su Yu loudly encouraged the soldiers: "Resist, reinforcements are already on the way!"

This sentence was purely a spiritual encouragement, but the soldiers believed it to be true, and with a little more strength out of thin air, the wood and stones rolled down, and the Wu army was killed and wounded.

Jiang Qin Zhou Tai saw that there was no thunder, and his heart was determined, and he ordered the crossbowmen to rush to the city to suppress the defenders at the head of the city, so they didn't care about the dead and wounded, and took the Vermilion Bird City, and added another county to Eastern Wu, which was a great feat, and it was worth killing thousands of people.

The Suzaku defenders did not have the protection of Su Yu's high defensive power, and suffered heavy casualties under the blow of the bow and crossbow, and when they were about to be unable to support it, there was a drum sound, and the new army that Wang Yuan came to support with the new army that got up from the bed, and the original Su Yu's healthy women's battalion also took action, braving the rain of arrows to treat the wounded, carrying supplies, baking flatbread, and sending hot water, to stabilize the situation at the head of the city, and the offensive of the Wu army was broken down again.

Jiang Qin and Zhou Tai are all generals, through several attacks, has figured out the bottom of the Vermilion Bird Army, Jiang Qin beat the drum to cheer, Zhou Tai carried a long knife to personally lead the troops to climb the city, the Eastern Wu Army is good at water warfare, more rope hooks and cymbals, Zhou Tai threw a flying claw up, put the knife in his mouth, rubbed and climbed the wall, jumped into the battlement, waved the knife to cut over several Vermilion Bird veterans, and went straight to Su Yu.

Zhou Tai did not have the slightest awareness of bullying women, through observation, he already knew that Su Yu was the backbone of this city, and taking her down, Suzaku was at his fingertips.

Su Yu raised his sword to fight, Zhou Tai is not comparable to those thin rookies, Su Yu's Wang Ba swordsmanship did not work, there was a clanging sound, Su Yu was slashed more than a dozen knives, if it weren't for the sturdy mecha, he would have been dismantled a long time ago, Zhou Tai was furious, he couldn't do anything with this turtle shell, his eyes looked at a sledgehammer on the ground, picked it up, threw away the long knife, and pounced with a cruel smile.

Su Yuhua's face was pale, the mecha could not break the defense, but whether it could be shockproof was a problem, and immediately activated the vector nozzle and flew into the air, Zhou Tai was stupid, he didn't expect the other party to fly.

Su Yu's courage increased greatly, swept over, grabbed his armor and threw him down the city, a bloody battle, the city fell a lot of soldiers' corpses, Zhou Tai smashed on it, spit blood, but did not fall to death, a group of Wu soldiers rushed over to rescue the commander, shouted and scolded loudly under the city, Su Yu remembered the fully armed weapons on his body, fired a rocket down, a dazzling fire lit up, and the city was suddenly quiet.

A chaotic battle reached dawn, and smoke and dust rose in the distance, Su Yu's heart was cold, they had just come to this era, and it was naturally impossible for them to be allies, it seemed that Vermilion Bird City was difficult to protect.

The Wu army sent a fast horse to the joint, and a quarter of an hour later, several points of light flew into the Wu army camp, and the continuous explosions blew up the Wu army to the point of a wolf howl.

Liu Yuan flew to the head of the city and saw that Su Yu's body was full of blood scabs, and he almost had a myocardial infarction, until Su Yu said that he was safe, this was the blood of the enemy before he put his heart at ease, and then he was angry, good you Dongwu dared to sneak attack my territory!

Under an order, Li Donglai was responsible for solving the surviving Wu army under the city, Li Donglai saw Guo Xiong behead Zhao Yun, a famous general who was blown into the sky, he was jealous in his heart, and he also wanted to kill the general, Zhou Tai and Jiang Qin unfortunately became victims.

The position of the boss in this era is too easy to recognize, the high general flag is the center, Li Donglai only takes the Chinese army, and the two generals are solo, and now there is no way to retreat, and the defenders of the city head are also following the drums and noise, and the two generals have to step forward.

Li Donglai is not a half-person like Su Yu, his special forces are retired, the fighting skills engraved in his bones, plus the mecha and long sword that are comparable to hanging in this era, but in a few rounds, Zhou Tai and Jiang Qin have become the souls of his sword.

The remaining Wu army had no way to retreat, and witnessed that the other party was so violent, so they had to surrender.

Su Yu and Liu Yuan converged, and after briefly talking about the previous situation, they asked curiously, "Where did you get reinforcements?"

"What, you said those people, that's not reinforcements, it's the people I gathered. ”

It turned out that after stopping Cao Jun's killing through intimidation, the trio was ready to go back, but they didn't think that their heroic posture of clashing back and forth in the chaotic army had been recorded by the panicked refugees, and after Cao Jun left, the bold man stepped forward tremblingly and asked if he could take him in, Liu Yuan thought that he needed the support of the people to fight the world and agreed.

The news came out, one spread ten to hundred, the surviving refugees in the Dangyang area got the news, and gathered one after another, Liu Yuan did not refuse, and all laughed, in order to integrate these refugees, organize migration, which delayed time.

After hearing this, Su Yu was a little worried, saying that it was a good thing for the people to defect, but the savings in the city were probably not enough to support so many people.

Liu Yuan smiled mysteriously, "Don't be afraid, someone will send it over soon." ”

Su Yu asked about Zhao Yun again, Liu Yuan didn't change his face and took out the video to show her, of course, it was edited, after Zhao Yun was killed, Liu Yuan asked them Guo Xiong and Li Donglai to rot this matter in their stomachs, Su Yu is Zhao Yun's brainless fan, after watching the battle video, I couldn't help but be disappointed, where is this white-robed young general in the game, he is clearly a middle-aged martial artist who has experienced vicissitudes, but his eyebrows and eyes are stronger than those crooked melons and cracked dates.

But Su Yu couldn't help but ask, "Where did he go later?"

"He was injured, and I wanted to invite him to Suzaku for treatment, but he refused, and still wanted to go to his lord Liu Bei. ”

Liu Yuan didn't blink his eyes when he said this.

The refugees who had been taken in had already come to Suzaku Castle, which was too small to accommodate so many people, so they had to temporarily set up tents outside the city, and the officials in the city mobilized one after another, and soon a letter arrived.

——

Yang Pingfan guarded strictly, and there were no moths along the way, the two of them landed at O'Hare International Airport in Steel City, Zuo Ci got off the plane, and saw black, white and brown people all over the ground, the appearance of people with different colors and skins, and his eyes were shining, "Brother Yang, you are really good to me, there are really ...... demons everywhere here."

Before the words fell, Yang Pingfan covered his mouth and pulled him into the car that had been waiting for a long time.

The crossing test was successful, Yang Pingfan also brought a helper back, which greatly increased the confidence of the resistance organization, and the general altar asked them to organize a crossing immediately, directly strangling Liu Yuan in his youth and even infancy, so that Yang Pingfan and Leonard sneered, what kind of character Liu Yuan is, how can he not realize this, maybe they will face the terminator of the entire army when they cross the past.

What they need most at the moment is to give full play to Zuo Laotie's ability as soon as possible.

Although it has been nearly two thousand years, Zuo Ci has not had a major panic, and has adapted to some of it when he was in the Ming Kingdom, and after coming to Citigroup Steel City, under the hand-in-hand teaching of Yang Pingfan and Dr. Leonard, he quickly mastered the skills of how to live in this era.

Without further ado, Dr. Leonard arranged another operation to enter the wall, capturing a superhuman inferior product and giving it to Zuo Ci for analysis and research, and Thomas, the chief scientist of the Resistance, arrived from Siberia to join the research team and solve the mystery of Company X's experiments.

Thomas, as Li Suifeng's beloved disciple, already knows the entire superhuman manufacturing process, but they are away from the Rockefeller Research Center and lack the most critical gene editing equipment, which is only available in national laboratories.

At the critical moment, Leonard proposed a risky method of experimentation, which was to edit the virus manually.

In this time and space they live in, it's not difficult to create a virus, really.

Many areas of biotechnology are advancing faster than Moore's Law. In 2000, it cost $300,000 to test a person's whole genome, but now it only costs a few hundred to a few thousand yuan.

In the lab, synthesizing a DNA sequence is already a piece of cake.

Scientists have successfully synthesized four yeast chromosomes and put them into yeast cells to work properly. Others have synthesized a completely artificial genome from M. genitalium from scratch.

In this good era, if you know the genetic sequence, it is not too difficult to replicate or adapt a virus without other additional requirements, such as enhanced infectivity.

A virus is nothing more than a piece of genetic material – DNA or RNA – with a shell on the outside. The latter is a product of the former and can be obtained by transfecting cells, etc.

So to make up a virus, the main thing is to write its genetic material.

Even amateurs can do this. In fact, many "biohackers" around the world are already in a position to do so.

Citigroup's FDA requires detailed documentation for human studies involving gene editing, but if a person conducts experiments in his own home and tests on himself, but there is no law on how to manage it, this is a loophole that resistance groups can take advantage of.

With a certain amount of expertise, tinkering with the genetic material of microorganisms is not difficult and expensive.

The powerful gene scissors CRISPR is an indispensable tool, and the full set of tools with tutorials is only $169 online, which can be D, IY bacterial genes.

There is no need to worry about raw materials, some companies will produce short fragments of chemically synthesized genetic material, which are inexpensive, can be purchased online, and viruses can be created by connecting them together in a very simple way and with enough patience.

As early as 2018, several scholars in the Maple Leaf Country used this mail-order raw material and used the simplest experimental methods to reproduce the virus with the largest sequence synthesized by humans at that time - horsepox virus in half a year, which cost less than $100,000.

If you're willing to pay more, there's SGI-DNA that makes desktop DNA printers for just $65,000 and can produce up to 32 3,600 base pairs in one night.

Even if you don't want to synthesize it from scratch, there are many other ways to play.

For example, add a new gene to an off-the-shelf microbe, add a new gene to an off-the-shelf microbe, and see what happens.

These are decades of proven technology, and they're cheap enough to be played as a hobby.

There are two main reasons why biohackers haven't destroyed the world yet.

First, most of the virus samples that are threatening to humans are not open to the public, and can only be obtained by biosafety laboratories of the corresponding level, and many technical details are not made public, and the operation is relatively complicated.

The other is that biohackers don't want to destroy the world. The madmen who really dare to experiment with themselves attract most of the media attention, but they are an absolute minority.

So around the world, conspiracy theories have always been directed at more organized, secretive-faced institutions, such as the military, scientific institutions, such as virus labs.

These institutions have been working for many years to toss the virus, and they have achieved great results.

As early as 2002, Citigroup scientists synthesized a batch of poliovirus completely from inanimate chemicals, and the contagiousness and symptoms on mice were almost the same as the original.

However, it is easy to make a virus according to a template, but it is much more difficult to adapt a virus in a specific direction.

It's not easy to get the virus to listen to you.

Viruses are simple and subtle, and a little tweaking can greatly enhance or weaken their pathogenic properties.
