"You're really not a god?" Zong Ze was a little incredulous, looking at the panorama around Bianjing.

"If you are a mortal, you can understand that I am also a scholar, but the place where I came from is relatively far away, and the books I read are different from yours. Bai Yan bragged.

"Brother Bai Yanxian, with this, it can be worth 100,000 male soldiers. I have a few sons who are not successful, and I am going to let them worship you as a teacher, what do you think, virtuous brother? According to the age of the seed master, Bai Yan's father is a little older, and he actually calls Bai Yanxian brother, his son is estimated to be not too small than himself, thinking that a few big men call themselves masters is actually quite beautiful, but they are boasting big, and the hardware and software of this Tianji system can't be rubbed out by hand.

"This, in fact, I am not too good at learning, although I know the principle, but I can't make it." Bai Yan said embarrassedly.

"Brother Bai Yanxian, I have a daughter who has not been out of the cabinet, young cardamom, beautiful and knowledgeable, after this battle, if you are free, you can see it." Li Gang also stroked his beard at this time and said with a smile.

Bai Yan looked at Li Gang's boxy face, and then thought about Cardamom's age, isn't it less than fourteen years old, and couldn't help but shudder: "Master Li, I take you as a brother, but you want me to be your son-in-law, it's not kind." ”

The crowd laughed.

Seed Master Dao carefully looked at the hologram of the battlefield, twisted his gray beard and said: "Two adults, Brother Bai Yanxian, with this map, although I dare not ensure that the field wave battle can win the Jin Army, but in the right place, it is possible to do some ambush and win one or two small victories." ”

Zong Ze looked at Bianjing City in the center of the map and said with some concern: "In this battle, the most important thing is that Bianjing City cannot be lost, as long as the official family of the Great Song Dynasty is still in the city, and the imperial flag does not fall, the Qinwang army from all over the Great Song Dynasty will be able to contain the Jin army, if the inner city of Bianjing is also breached, then my Great Song Dynasty will be in danger." ”

"By the way, General Chong, is there a huoyao in our army?" Bai Yan asked the seed master.

"huoyao, there are some, there are also craftsmen in the army, making some thunderbolts, earth-shaking thunder, and some role when defending the city, but when fighting in the field, the effect is not great." The seed master said truthfully.

When Bai Yan was in high school, he was also more interested in some military knowledge, and he also knew a little about the formula of black huoyao, including yellow powder, although he couldn't make it now, but he knew the best formula for black huoyao, and how to exert the power of black huoyao, he had also studied.

Although you can't make a gun now, you can't make a cannon, that thing has high requirements for steel, and without an industrial base, it is difficult to mass-produce. But it's not too difficult to build some earthen grenades and enhance some combat effectiveness.

Bai Yan explained that where he came from, there was a kind of knowledge that could increase the power of huoyao.

Li Gang and the others were very curious about where Bai Yan came from, but when they saw that Bai Yan refused to say, they didn't ask, so the planter called the craftsmen in the army, and according to Bai Yan's request, they took saltpeter, sulfur and charcoal. Bai Yan instructed them to purify the three materials and mix them into powder in proportion, this step is not much different from the original process of the military craftsmen, but many times, the huoyao made can only be burned quickly, and it cannot form an explosion, even if it explodes, the power is not great. This is because the black huoyao powder, due to the mixing of the ratio of the three raw materials, after standing for too long, due to the relationship of specific gravity, there will be delamination of powder, resulting in uneven proportion, and the huoyao of the Song Dynasty is far from reaching the best ratio, so the huoyao of this era almost has little effect on the battlefield.

However, on the one hand, Bai Yan provides the best ratio of huoyao formula, including some processes for purification, and the most important thing is to granulate huoyao. Bai Yan asked the planter to get some egg whites, mix them with huoyao powder to form a paste, and then rub them into thin strips, let the craftsmen put them outside to dry, and after drying, let the craftsmen cut them evenly into one grain at a time, and then mix some iron nails and the like, find a bamboo tube, stuff it in, you can find a place where no one is around, light a fire and try it, Bai Yan also told the planter that this thing is very powerful, you must pay attention to safety.

The planter will be suspicious and let the craftsman prepare. In the evening, Zong Ze prepared a dinner party to entertain Bai Yan. Zong Ze and Li Gang were both literati, and they were very curious about Bai Yan's knowledge. Bai Yan boasted a bit big, but he was also educated in basic education, and he used Newton's three laws, Einstein's theory of relativity, including astronomy and geography, and other knowledge, to drink and eat, and brag nonsense, but shocked Zong Ze and Li Gang as heavens.

The sun sets, the moon waxes and wanes, and the seasons change, so that's it? Both of them are drunk, this world is so reasonable, it is so simple, this so-called universe is so vast and majestic.

Seed Master Dao is a martial artist, but not as nerdy as Li Gang and Zong Ze, although this knowledge sounds quite powerful, but the most important thing is to keep Chen Liu, and after three rounds of drinking, he will inspect the city defense.

In fact, there is no need, Bai Yan has already ordered to scout the flying insects and conduct a vigilance in the sky above Chen Liu, even if there is really a sneak attack by the Jin army, it can't hide from the eyes of the sky.

At night, Zong Ze arranged a place for Bai Yan to rest, and Bai Yan finally had time to have a good chat with the demon lord carving, after all, how to go back is what Bai Yan is most concerned about.

"The singularity of going back has not yet appeared. But your Dimensity system is really powerful, you can let your reconnaissance flying insects load a task to detect the singularity, but if you find the singularity, it also means that you have discovered the Protoss, after all, you and I are both stumbling blocks to the invasion of the Protoss, and this time secret realm is essentially to trap us here. The Demon Lord Seal explained.

"Protoss, didn't you say that they couldn't get over because the speed of light in the universe can't exceed the law?" Bai Yan asked.

"Of course, the ontology of the Protoss can't get by, it can only be their projection clone, and the projection clone can come to the secret realm through the singularity, and once it reaches this time secret realm, it will also cut off contact with the ontology. But the projection clone carries the coordinates of the singularity on it, and once it is destroyed, the singularity will be reopened, and we will be able to find our way back. The Demon Lord Seal explained.

"What are you doing with the projection clone of the Protoss?"

"Of course they came to destroy us, our existence blocked the invasion of the Protoss, they created the secret realm of time, and also pushed us in, but at the same time, it also allowed me to grasp part of the secret of time. This time secret realm is a cage that traps us, but at the same time, I am also reversely cracking the mysteries of their secret realm, and it is estimated that they have also discovered this, so they will send clones to destroy us. "The Demon Lord carved the seal.

"What, what did you find when you cracked the mystery of the secret realm of time?"

"Time is like a long river, and in this long river, the Protoss has created a tributary, which is the secret realm where we are now. Our secret realm is actually a branch of the Overworld, but when they created this tributary, I found a loophole, and I can also gently open a stream in this Overworld. The Demon Lord said.

"I can't understand human language."

"I can open up a space-time singularity, and after going to it for sixteen years, the time is only five days."

"What's the use of that?"

"Yue Fei was killed at that time, if you have time, you can take him and his Yue family army for a trip."

"Is that awesome?" Bai Yan is overjoyed.
