These homemade black powders were relatively crude, and even though Lin Shuhang had followed a strict mixing ratio, they were still not very powerful.

I definitely don't want to think about grenades, but it is enough to make firecrackers.

The best material for making the cannon body was paper, but during the New Dynasty, paper was not popular, and even Kunyang City could not find a few pieces, so bamboo tubes were used instead.

The production method was all found on the Internet before. It is relatively simple. Cotton thread is wrapped with gunpowder to act as a lead, and some pigments are added to the gunpowder inside the bamboo tube.

It is impossible to create those modern colorful and large-scale fireworks. You can only simply spray tongues of flame and finally explode directly.

Simple is a little too simple, but after all, it is the black powder formula of later generations. Lin Shuhang experimented several times and found that the power is quite good. The sparks exploded from a small bamboo tube can splash to the surrounding area of ​​seven to eight square meters, and the spray can reach three meters.

Four meters high.

In addition, the Chung Ling Army's salt-making brigade actually discovered a talent, which gave Lin Shuhang an unexpected surprise.

Li Changfu had considerable wealth before joining the Green Forest Army. Unfortunately, his family fell into decline after the promulgation of the New Deal, which is similar to the situation of Lin Yinu's family.

This person has been fond of seeking immortality and refining elixirs since he was a child. He is actually a serious alchemist. He was very excited when he was sent by Wang Ba to boil saltpeter. He claimed that he also had a recipe, which was to put charcoal, urine, lime and sand together.

It is heated and distilled to obtain a white granular shape. Its burning effect is better than that of saltpeter. It is extremely flammable and can burn endlessly if it is touched with meat. It will burn until your intestines are broken. He calls it 'yin flint stone'.

'.

When Lin Shuhang heard this, he thought, isn't this 'white phosphorus'... According to modern historical records, this thing was only discovered by the German Brandt in the 16th century. However, he did not expect that China already had it as early as the Han Dynasty.

.

This was a good thing, so he quickly allocated manpower and materials to Li Changfu and asked him to produce it in large quantities. He waited until the fourth day to get it out. Lin Shuhang added a small amount to the last batch of firecrackers, and let him continue to make large quantities of the rest.

manufacture.

The sneak attack on the beast camp is just a powerful means to boost one's own morale and destroy the new army. The subsequent battle to defend the city will definitely still be difficult. Having a sharp weapon like white phosphorus will definitely be of great help to defend the city.

As for the impact on history... Ever since Li Changfu appeared, Lin Shuhang has looked away a little.

White phosphorus has been discovered by Chinese people a long time ago, but it has not become a climate phenomenon and is not even recorded in history.

Including gunpowder, it was obviously invented by the Chinese first, but a thousand or two thousand years later, it is still at the stage of making fireworks and firecrackers... If you get black powder in advance, the impact on history will probably be minimal.

After all, the inheritance and development of a civilization are determined by people's ideology, rather than one or two simple inventions. I seem a bit too unfounded.

On the morning of the fifth day, the baggage of the new besieging army had arrived, and dozens of rams and catapults began to be pushed to frontline positions in all directions for assembly.

Kunyang City is small. Although the city wall is strong, it is only three feet high and five feet thick. How can it withstand the destruction of these heavy siege weapons?

In addition, there was no trace of Liu Xiu's reinforcements and no news, so the morale of the Green Forest Army inevitably fell off a cliff.

In the last simulation, the proposal for the Chongling Army to imitate Liu Xiu's breakthrough and destroy the enemy's engineering weapons was once again put before the top brass of the Green Forest Army.

Suggestions came one after another in the hall, mostly from Wang Feng and Wang Chang's old subordinates. They were not pleased with Liu Xiu, but also disliked Wang Ba, who had gradually become favored in the past two days.

But Wang Feng Wang Chang was a little embarrassed. After all, Wang Ba of the Chung Ling Army had shown kindness to them several times in the past few days, and he had the intention of abandoning the dark side and turning to the bright side. Moreover, this man was skilled in martial arts and full of knowledge, so he was asked to die. Wang Feng Wang Chang still responded.

I really can't bear it.

Unexpectedly, Wang Ba readily agreed and did not need any support, just the headquarters of the Ling Army.

The Chongling Army only has three to four hundred people, most of whom are old, weak and disabled, and only a few hundred are truly capable.

With just such a small number of manpower, do you dare to launch a surprise attack on Nanying?

There were many people in the army waiting to see the joke, and some thought Wang Ba and the Chongling Army were going to die tragically, but no matter what, the quarrels always stopped.

…………On the evening of the fifth day, in the hut.

The firecrackers have been made, a total of 300 firecrackers, and five of them are packed in a large dark backpack, weighing hundreds of kilograms.

The boiled saltpeter and white phosphorus are still being produced continuously, but Lin Shuhang no longer plans to continue to equip them. These are enough. No matter how much, he, Wang Ba and a few selected elite players will not be able to get it by then.

The room was clean, Lin Shuhang was walking in Fuxi's confused footsteps, and Little Zhou Tian's mind was running slowly.

I have been too busy making firecrackers these past few days. At night, I have to go to the top of the city to use night vision binoculars to observe the enemy camp's branches and patrol hidden posts, etc.

There is no time to practice the sword technique, and the proficiency level is still at 689/1000, but Xiao Zhoutian Xinfa still squeezes out a little time to practice every day, and he never insists on it too fast. He only needs to increase ten points step by step every day.

As long as you break through the Xiantian realm before taking action tonight, even if you fail and die tonight, you can still purchase spells in the Cause and Effect Mall after exiting.

The data is all stuck. When the last little Zhoutian mental method is completed, the spiritual energy increases.

[Ling Yuan: 1000 (Foundation Building Realm)]

When the data on the personal panel jumped, the abundant spiritual energy in the dantian seemed to suddenly expand rapidly. Normally, such a speed would burst the dantian in an instant and go crazy.

But at this moment, the expanding spirit energy seems to have opened up another 'dimension'. Although it is constantly expanding in the dantian, it does not feel swollen at all, as if the entire dantian has completed a deep transformation at this moment.

, becomes without 'boundaries'.

Some new knowledge also poured into my mind.

This is the advantage of using a simulator to practice. First, there are no bottlenecks. Breakthroughs will occur naturally when the data arrives. Second, there are supporting theories. Once you reach a certain state, you will naturally have knowledge principles that match that state, without the need for a teacher to guide and guide you.

Teach, because the simulator is your best teacher.

The knowledge in his mind is obscure and profound. According to Lin Shuhang's own understanding: the Dantian used to be in the body, and its existence could be truly felt. It could be called a substance in the 'three-dimensional world'.

The current 'Dan Tian' cannot be called Dan Tian, ​​but can be called Qi Hai. It does not exist in one's body, but it is very closely connected with oneself.

This feeling is the same as that of "Tao Zed". In modern terms, it seems to exist in the "fourth dimension", a fourth dimensional space that belongs to you alone.

Lingyuan practice itself is a process of breaking through the barrier between the three dimensions and the fourth dimension, and the so-called "fourth dimension" defined in this way is actually the world of spirit.

Lin Shuhang now understood why he had to reach the Foundation Establishment Realm to practice magic, because before reaching this stage, you would not be able to feel the existence of the spiritual world.

The ghosts seen in the Mausoleum of the First Emperor were products of the spiritual world, and spells were also products of the spiritual world.

Spiritual energy is the energy required to communicate between the three-dimensional real world and the four-dimensional spiritual world, which is roughly equivalent to what modern scientists call "dark matter".

The way you cast spells, interact with ghosts, etc. are the means and bridge for you to communicate between the two worlds.

Both worlds coexist in reality, but the lower dimension cannot directly see the higher dimension, just like two-dimensional creatures cannot see or understand three-dimensional creatures.

The opposite is true, so ordinary people cannot feel the existence of spirits and cannot understand ghosts and gods.

To outsiders, it seems very complicated and mysterious, but to those who have entered the door, it is actually a casual action of opening and closing the door. When you truly understand the so-called "spirit", everything becomes like this.

Simple.

Lin Shuhang couldn't help but think of what the Emperor had said to him in the beginning: Immortals are not what ordinary people imagine, but they are actually far less mysterious.
