Sun Jian annihilated the Jiangxia naval army, knowing that he had completely torn his face with Liu Biao, so he decided to abandon Changsha and march into Jiangdong in advance.

In just a few days, the grain and grass were ready. Sun Jian exhausted his elite and personally led the army to the battle, leaving only the veteran Huang Gai to lead 5,000 elite soldiers to stay in Changsha to protect Lu Yao.

Sun Jian's army went out, and Lu Yao was not idle.

The road from Changsha to Moling is long, although Sun Jian got the 200,000 troops he sent, but he didn't want to fight Moling in a short time. Therefore, he had to hope that Lu Gong's secret record would allow Huang Yueying to research black technology to help Sun Jian.

"Lord Wang, this book is really a divine book." Huang Yueying happily flipped through the secret record of Duke Lu, and was so happy.

"What's written on it?" Lu Yao asked with a light smile.

"Sharpen the ink for me." Huang Yueying's spirits lifted.

Sun Shangxiang and Ma Yunlu immediately ran over and sharpened the ink for Huang Yueying. Looking at that proficiency, it's obviously not the first time.

In front of Sister Xueba, these two little girls are scum.

Huang Yueying waited until the two little girls polished the ink, and praised them very much, which immediately made the two girls very happy, and waited behind her upside down.

Lu Yao was curious. According to the paper, Huang Yueying has been taught by Huang Chengyan since she was a child, and she is not inferior to Cai Yan. But Cai Yan couldn't do Huang Yueying's this, and trained the lively and eccentric Sun Shangxiang and Ma Yunlu to be more obedient than puppies.

Just thinking about it, Huang Yueying had already written down the various props recorded on Lu Gong's secret record on the paper and pushed them in front of him. He perked up, immediately put away his distractions, picked up the paper and examined it carefully. As soon as he saw the first prop, he couldn't help but widen his eyes, Huo Di got up, and he was in a good mood.

Divine Fire Flying Crow: An ancient strange weapon contained in the secret record of Lu Gong, shaped like a flying bird, with a range of up to 1,000 steps, and exploding to injure the enemy after landing.

Black technology, proper black technology.

According to the prop introduction, this Divine Fire Raven can basically be regarded as a missile, especially with a range of 1,000 steps. According to the Han system, one step is equal to six feet, and one foot is equal to 23.1 centimeters. In other words, the range of the Divine Fire Flying Crow is more than 1,300 meters.

The other props below, Lu Yao is no longer interested in watching. Just like this Divine Fire Crow, it is a well-deserved supreme weapon on the battlefield. For him, a player accustomed to modern warfare, the Divine Fire Raven must be at the top of the list no matter what.

"Start researching this right now, just come to me as soon as you need it." Lu Yao pushed in front of Huang Yueying, and his fingers focused on the Divine Fire Flying Crow.

Huang Yueying didn't know why Lu Yao valued the Divine Fire Flying Crow so much, and even ignored the other props. However, seeing Lu Yao's solemn appearance, Bing Xue was as smart as she naturally wouldn't contradict it, and nodded obediently.

Lu Yao immediately ordered someone to call Huang Gai, who was staying in Changsha City, and told him that he must ensure that Huang Yueying's research should be needed. Although Huang Gai was curious, he also accepted the order truthfully.

In the following period, there was a lot of good news ahead. The new Jiangxia naval ships, Sun Jian's soldiers attacked Yangzhou Yuzhang County by land and water. In just a short period of time, more than ten counties were connected, approaching Nanchang City, the seat of Yuzhang County, and almost occupying the entire Yuzhang County.

A few days later, Yuzhang Taishou Zhu Hao surrendered the city, and the entire territory of Yuzhang County was returned to Sun Jian. Sun Jian occupied Yuzhang County like a bamboo, and after a short rest, he immediately sent troops to Poyang County.

Hearing that Sun Jian was marching into Poyang County, Lu Yao was in a very good mood. Take Poyang County, and then pass through Xindu County, you can go straight to Moling. He carefully calculated that there were no famous princes in Yangzhou during the current period. According to the current progress, it will not be long before you can set sail from Moling and return to Xanadu City.

At this time, Huang Yueying hurriedly walked over, and when she saw Lu Yao, she saluted happily: "The little girl is fortunate not to be dishonored." ”

Lu Yao got up, surprised and delighted, and hurriedly asked Huang Yueying to take him to see this Divine Fire Crow comparable to a missile.

The Divine Fire Raven injures the enemy with an explosion, but it is not a gunpowder weapon. There is no need to think about it, Pangu obviously also knew that gunpowder was an invention that subverted the times, and did not admit gunpowder, making it impossible for players to develop it. However, because it could also explode, Lu Yao set up Huang Yueying's research site outside the city, and specially sent Gao Shun and the Eight Hundred Trap camp guards to protect him.

When he came to the workshop, Lu Yao saw this ancient artifact at first sight.

The Divine Fire Flying Crow is about one zhang high, which is more than two meters according to the Han ruler and about eight feet long. The whole is just as recorded in the secret record of Lu Gong, the shape is like a bird resting on a wooden frame, with wings to maintain balance, and the bird's belly is naturally loaded with explosives. It's a pity that Huang Yueying couldn't find out what kind of explosives it was, so naturally she couldn't make it in batches.

"Lord Wang." Huang Yueying was obviously very excited, and trotted to Lu Yao with a torch, signaling for Lu Yao to conduct the first test in person.

Lu Yao didn't mind and took the torch. The test is dangerous, but he believes in Huang Yueying's talent, and even more believes that Lu Gong's secret record will not be selling dog meat on the head of a sheep and making a defective product, otherwise he will not be qualified to put it in the royal treasury.

According to Huang Yueying's instructions, Lu Yao lit the fuse with the torch. Not long after, the Divine Fire Crow brought up a cloud of black smoke and flew into the air with a whistling voice. Under the clear sky, the Divine Fire Crow crossed a steady arc and landed a thousand steps away, and in an instant, the fire suddenly appeared, and thick black smoke rose with the sound of explosions.

Lu Yao's heart was settled, and he immediately turned over and got on his horse, urging the snow treading black horse to go over to see the effect of the explosion. When he got there, he didn't wait for the snow to stop, he immediately turned over and dismounted, and ran to the explosion site to check.

A shallow crater about one meter in diameter and about twenty centimeters deep appeared in the ground. The surrounding area is pitch black, showing signs of being burned by high temperatures.

Lu Yao frowned.

Frankly, he wasn't happy with the Divine Fire Crow. With such a large size, the explosion effect is only that. Strictly speaking, it is okay to harass, or disrupt the enemy's formation, or to demoralize the enemy, but it may be costly to reproduce modern warfare.

At this time, Huang Yueying and other generals arrived. Lu Yao called Huang Yueying and carefully inquired about the cost of the Divine Fire Crow, the time of the finished product and other information. In the end, the answer was not optimistic.

According to Huang Yueying's research, it takes about five days to complete a Divine Fire Crow. But this has to be the result of the entire Changsha city to fully supply the required resources. After completing the first Divine Fire Crow, the entire Changsha City has consumed a lot of necessary resources, and at most two more Divine Fire Crows can be created.

The higher the expectations, the greater the disappointment.

Lu Yao is in this mood at the moment. I thought that I got black technology, but it turned out that there were obvious flaws in black technology. The black technology that can't be mass-produced really can't satisfy him.

However, black technology is black technology after all, and no matter how small the number is, it cannot deny its superiority in the game. Lu Yao cleaned up his mood, told Huang Yueying to continue to create the Divine Fire Flying Crow, and returned to the city with the generals.

As soon as he returned to the city, Huang Gai hurried over, and as soon as they met, he said worriedly: "Lord Wang, Jingzhou Liu Biao has committed a crime." ”
