From the point of time, it is still two months since Lao Nu attacked Fengji Fort, so it is too early to dispatch troops now, and will be noticed by the ubiquitous Later Jin Xishu. But Gao Shixin felt that it was still necessary to check the terrain of Fengji Fort.

"Yongwazi, Jiannu may not have attacked so quickly. They should not come after the New Year. Let's check the terrain first and then decide how to fight." Gao Shixin said. He thought to himself: Since you already know when Jiannu will attack, instead of passive defense, it is better to check the terrain first and then decide whether to ambush or choose favorable terrain blockade.

If the terrain is favorable, an ambush can be set up and a beautiful ambush battle can be fought. If the ambush is successful, maybe it will be possible to shoot the old slave to death with one arrow, causing Jiannu to be defeated on the entire line.

"Brother, if you know how to fight, you will follow yours. Let's look at the terrain first." Zhang Yong agreed immediately.

Gao Shixin wore a wingless black gauze hat, a big red flying fish suit, a gold belt around his waist, a jade waist tag, an embroidered spring knife, and a black horse. Zhang Yong wore a second-grade six-race crown, a python robe, an ivory card around his waist, and an embroidered spring knife, and a red horse given by Emperor Tianqi. The two brought one hundred Jinyiwei and twenty Dongchang men to Fengji Fort. These Jinyiwei and Dongchang men were elites brought by Zhang Yong. Each of them carried a self-generated musket, equipped with fifty paper shell fixed-loading bullets, a gun sword, an embroidered spring knife, and four most advanced hair pulling grenades. Some factory guards also had their own weapons, such as flying knives, darts, page hammers, axes, etc.

These factory guards are all masters, and the weapons they use are all carefully crafted and exquisite weapons. The self-produced musket was made of imitation of the French dog-locked flintlock rifle. This gun was designed by Zhang Yong. The Tianqi research was successfully made into samples and handed over to the Ministry of Works. Liangjiang was hired to create a high price to create the steel plates used to build the gun barrels and the iron used to build the gun barrels were all brought back by Gao Shixin from Fujian.

The rate of fire of a self-generated musket is much faster than that of a bird gun. Using a self-generated musket with a paper shell fixed-loaded bullet, a skilled musketman can fire six rounds in a minute!

The pull-hair grenades equipped by these elite factory guards are also new weapons jointly developed by Zhang Yong and the carpenter. The grenade has a wooden handle, a fuse and a fire pulling device made of red phosphorus, copper wire, sulfur and broken glass powder. When used, just unscrew the safety cover behind, then pull the pull-hair rope, and then throw the grenade out.

In ancient China, yellow phosphorus was easily obtained. There were two kinds of natural phosphorus ores, one with high phosphorus content, which was easy to burn; the other with low purity was not easy to burn. In ancient times, the phosphate ores that were easily burned were used by wealthy people as a beacon in the tombs; the phosphorus that was not easy to burn was used as flint, and was knocked off with iron sheets to knock off the stones outside. The phosphorus inside would ignite spontaneously when it encountered air.

With Zhang Yong's brain, it is not a piece of cake to extract yellow phosphorus from the phosphorus ore? After extracting yellow phosphorus, it is processed into red phosphorus that will not spontaneously ignite when it encounters air, and then a safety match is obtained. Then, the principle of safety matches is used to create a fire pulling device, which is a new type of grenade that is close to modern grenades.

Zhang Yong also set up a scientific laboratory with Emperor Tianqi. The emperor did his carpenter work and assembled machinery, while Zhang Yong conducted some chemical experiments, made some novel items, and even planned to improve gunpowder and make explosives.

The black gunpowder grenade used now is really unsatisfactory, so Zhang Yong needs new gunpowder and even explosives to make grenades.

However, the grenades equipped by the factory guards are already quite advanced weapons. The bullet body cast from ceramic contains thirty iron beads. After the explosion, the ceramic can form fragments to kill the enemy. The iron beads inside fly out and form a killing radius within a radius of six meters.

Each Jinyiwei and Dongchang Fanzi Xiaoqi also carried a five-tube self-generated tiger-wing gun. The so-called tiger-wing gun is an enhanced three-eyed gun, which turns the original fire gate-type ignition into a trigger-rack-type ignition, called a tiger-wing gun. The five-tube self-generated tiger-wing gun jointly developed by Zhang Yong and the little carpenter strengthens the three-tube to five-tube, and changes the grenade gun to a flintlock gun. This kind of tiger-wing gun, after one round, can fire another round as long as the gun barrel is turned, and can fire five projectiles in a row.

Seeing Zhang Yong and Gao Shixin leaving Liaoyang with a group of factory guards, Yuan Yingtai asked, "Where are you two going?"

Zhang Yong snorted coldly and said in a word: "Jinluo Yuan, are you too concerned about it? Our factory and ward have to explain to you where to go?"

Yuan Yingtai was speechless because of the criticism. The factory guards were not under his control. Not to mention that Zhang Yong, the military supervisor, could not control him, even Gao Shixin, the assistant chief of the Jinyiwei, had no right to control him.

The little castrated dog is so domineering! Yuan Yingtai cursed in his heart.

Gao Shixin originally planned to ignore Yuan Yingtai and let Shenyang fall and let Yuan Yingtai die in Shenyang. However, he couldn't do such a thing. If he didn't help him, he could use Jiannu's hands to get rid of Yuan Yingtai. However, in order to kill Yuan Yingtai from the Donglin Party, he would have to cause millions of people in Liaodong to suffer. Gao Shixin felt that his conscience would be very painful.

Fengji Fort is not far from Shenyang, and it is 150 miles from Liaoyang to Shenyang. It is more than a miles from Liaoyang to Fengji Fort. It took only two days for Gao Shixin and Zhang Yong and others to arrive at Fengji Fort.

Seeing a group of factory guards coming, the Fengji Fort Guard Li Bingcheng hurried out of the fort to greet him.

Li Bingcheng was also a general of the Sichuan Army transferred from Xiong Tingbi from other places. He stationed a thousand white-sling soldiers in Fengji Fort. In the original time and space, Lao Nu attacked Fengji Fort and was defeated again and again by the white-sling soldiers, forcing Lao Nu to attack Huangshan in the north. Because the Huangshan guards fled without fighting, Lao Nu then surrounded Fengji Fort.

When he saw Gao Shixin and Zhang Yong, Li Bingcheng asked: "Sir Gao and Eunuch Zhang, why are you here?"

Gao Shixin asked back: "General Li, don't you think that what happened in Liaodong has been abnormal recently since Yuan Jingluo came to Liaodong? Batches of Baoyi escaped from Jiannu's land. Why is this?"

Li Bingcheng was quite mindful: "Sir, I think that Jiannu must have installed countless works in it!"

"Yes!" Gao Shixin nodded in approval, "Now that Liaodong has been penetrated into a sieve by Jiannu! Jiannu has made such a big fanfare, what will they do next?"

"We must make a big attack! Now Jiannu has destroyed the Yehe tribe and is completely connected with the Korqin Tartars. Jiannu's strength has increased several times! They must be preparing to attack Liaodong!" Li Bingcheng replied.

"That's right!" Zhang Yong said, "Our family analyzed that Fushun Pass, Qinghe Pass, Kaiyuan and Tieling have been repaired by Xiong Jinglei, and heavy troops have been stationed. Moreover, Liaoyang, Shenyang, Tieling and Kaiyuan are all connected together. If Jiannu attacks Kaiyuan or Tieling, our reinforcements will arrive at it. Jiannu cannot encircle all sides, so they cannot surround the reinforcements! They will only gain more than they deserve to attack Guancheng. Therefore, our family judges that Jiannu will definitely use it as a breakthrough from you!"

Li Bingcheng sneered: "If Jiannu dares to come to Li, he will definitely teach him that he will never come back! The thousand white-rod soldiers under Li's command are not vegetarians!"

Gao Shixin asked: "Who is the guardian of Huangshan Fort opposite?"

"Liaoyang guerrilla general Cao Xiyuan." Li Bingcheng replied.

"Cao Xiyuan?" Hearing this name, Gao Shixin and Zhang Yong were shocked at the same time.

Who is Cao Xiyuan? When it comes to Cao Xueqin, everyone knows it. Cao Xiyuan's son Cao Zhenyan is Cao Yin's grandfather, and Cao Yin is Cao Xi's son, Kang Mazi's personal bodyguard, and later served as the Jiangning weaving factory. Cao Yin's grandson is the famous Cao Xueqin.

Cao Xi is Cao Zhenyan's son, and Cao Xi's wife is Kang Mazi's wet nurse, so Cao Yin and Kang Mazi are brothers and sisters. This family is a traitor for five generations!
