Yang Lin's conversation with the three gods lasted all night, in order to fool them into their own warship, Yang Lin almost had to answer their questions, for the development direction of the Daomen, Yang Lin's guidance was to let them develop to the pharmaceutical industry, using their own advantages in the Taoist temples all over the world, to develop a set of medical system, while accepting the sesame oil money of the believers, the great merit of curing the sick and saving people was implemented to the people, as long as the Daomen insisted on curing the sick and saving people, no matter where they went, they would be respected by the people, and the ruler would not take such an organization. For the development direction of Buddhism, in view of the fact that their power was not great in the early Tang Dynasty, Yang Lin felt the need to remind them to go west to learn scriptures, of course, not to ask them to go to India to get Buddhist scriptures, but to tell them to go west along the direction of the setting sun, to explore, to find the species of this world, if many years later, the Tang Dynasty changed their lives because of some species brought back by monks traveling thousands of miles, they would remember the merits of Buddhism, and similarly, explorers like them are also needed by the people.

As for the Divine Human Race, Yang Lin's advice was, hurry up and let the whole clan go out of the mountain to join me! When it comes to understanding the microcosm, if you hide in the mountains and study the extermination of the race, you may not be able to catch up with me, so it is better to bring them out as soon as possible while your race is not extinct.

The three gods left with restless steps, Yang Lin didn't take what he said today as a secret at all, I believe that Chun Tao, who has been guarding the Drunken Immortal Building, will report some of the situation here to Li Er, and after returning to the palace, I am afraid that there will be a mouth-wrenching explanation, so Yang Lin stayed overnight in the Drunken Immortal Building for the first time, although there was no girl to serve.

Sleeping until the sun turned west, Yang Lin woke up and was caught under his arm and ran wildly, now he can be regarded as a person who has seen the world, and he can take away his own at any time in Chang'an City, except for the inner servants in the palace, there are only the inner servants in the palace, Yang Lin squinted his eyes and saw the person who was running between himself, as if he was urging Erfan.

"What's wrong with the palace?"

"It exploded."

Urging Erfan to run out of breath, thinking that Li Er's order was very anxious, it must be Li Ke's side that made some mess, he didn't want to play himself to death, Yang Lin was still in a hurry to urge Erfan to run at first, this will start to think that he is running slowly, if there is Ji Wutong's speed, this will already be to the palace.

A large number of Qianniuwei gathered in the palace of King Wu where Li Ke lived, and the entire palace had already entered a wartime state of alert, urging Erfan to pass through many checkpoints to bring Yanglin to Li Er, thank God, Li Ke, who was wearing a black and tattered shirt, was still alive, and he was kneeling down in front of Li Er to enjoy his scolding.

"Father, the son can't explain clearly, let's talk about Xiaolinzi!" Li Ke saw Yang Linran as if he had seen a savior, and hurriedly kicked the ball over, looking at the ruins of the Wu Wang Palace, Yang Lin knew that there was probably a lot of gunpowder that was detonated, and even many small side halls around it were collapsed by the aftermath of the explosion, and casualties were inevitable, only to blame Yang Lin for not being able to carefully describe the power of gunpowder at the beginning, especially the power of the golden ratio ** he gave.

"Father, this is a matter of importance, so let's let the left and right retreat before we can speak." The sleepy-eyed Yang Lin looked at the corpses that had been cleaned up by the eunuchs, and felt very uncomfortable, gunpowder is not an absolutely safe way to make it in the future, not to mention now, looking at the hint of excitement in Li Ke's slightly frightened eyes, Yang Lin felt the need to give them some knowledge of gunpowder, the palace maid eunuch and Qian Niuwei all retreated, and even the crying Yang Concubine was taken down by the eldest grandson, and there were only a few men left in the field, Li Er and his three sons, Yang Lin.

If Li Ke's eyes can still find a trace of excitement, then Li Chengqian and Li Tai's eyes have a trace of incomprehension and resentment, Yang Lin and Li Ke actually have a secret that their two brothers don't know, this is a very dangerous signal, don't doubt why the twelve or thirteen-year-old boy has such a mind, they grew up in such an atmosphere, the battle in the palace is everywhere, but their means dare not be imposed on the extremely smart Yang Lin.

"Father, the second brother is developing a secret weapon given to him by Professor Erchen, I'm afraid that something will cause an explosion if something happens in it." Yang Lin couldn't explain anything to Li Chengqian, gunpowder is not something that young people should be contaminated, if Li Ke strictly follows the process formulated by himself, this cold winter wax moon should not be easy to cause accidents, it seems that he should want to see what kind of power this thing has, curiosity is the root of this accident.

"What it is, tell me in detail."

Hearing that it was a weapon, Li Er's eyes lit up, a weapon that can raze dozens of zhang to the ground, is there anything in this world that can stop it?

"This thing is called gunpowder, and it can be called a bomb after it is successfully made, and it is made of sulfur, saltpeter, and charcoal in a certain proportion, and it is sealed with a fixed sealing device, leaving a lead, and taking fire to ignite the lead, which can produce a violent explosion, and the result of the explosion is just like what His Majesty saw." Yang Lin pointed to the ruin-like palace of King Wu, and at the same time asked Li Ke in a low voice, "How much gunpowder did you detonate?" ”

Li Ke didn't dare to make a sound, and gestured a shape the size of a small jar with his hand, and Yanglin had a black line on the spot.

"If your baby were the whole big altar, Datang would die in your hands." Yang Lin couldn't help but roar, this thing is not suitable for development in a place where there are people, especially for these curious young people to develop, gunpowder is put in the air and ignited, that is, it burns quickly, once a large amount is sealed, it is not as simple as burning, Li Ke This is a miscalculation of the energy of the bomb device to amplify the power of gunpowder.

Yang Lin was scolding, but Li Er was trembling, as Li Ke's son, he was more curious than him, and asked to see the power of gunpowder with his own eyes on the spot, but Yang Lin naturally refused, this thing must be found in a desert where no one can test it.

"Father, the power of gunpowder is enough to make all the forces that dare to rebel against my Tang Dynasty bow their heads, but they must also be cautious when using it, its raw materials are not difficult to find, once it is mastered by people with ulterior motives, the consequences are unimaginable, and now there are only a few people who know the correct configuration of gunpowder, I think it is not appropriate for more people to know, the power of gunpowder, we have to choose a secret location, and conduct secret tests, including the news of the explosion in the Wu Wangdian today, Your Majesty Xià had better also order a blockade,, Once the power of this thing is spread, I am afraid that the palace will not be at peace again. ”

Yanglin's Jianyì Li Er thought so, if such a killing weapon detonated in the palace for the second time, not to mention the loss, it would be difficult to appease the people's hearts, and after a while, Li Er summoned Ma Yongquan and told the six palaces, the palace of Wu Wang was in disrepair and collapsed, and the palaces did not need to panic, check their respective residences by themselves, whether there was any damage, and report to the inner government for repair.

At dusk, a big carriage carried a cart of jars and jars out of the imperial city, taking advantage of the city gate was not locked, out of Chang'an, on the carriage, Li Er looked at a few wooden boxes covered with withered grass like a baby, Yang Lin had reminded him more than once, this thing should not be too close, and after he developed a safe detonation device, people can get in close contact with this thing, and the three brothers Li Chengqian outside the carriage were thinking about things in their hearts, and they had not said a word since the afternoon.

The carriage walked outside the city for two hours, and it really stopped when it came to a deserted suburb with no road, the moon in winter was big and bright, but let a few eunuchs who accompanied him quickly investigate the surrounding environment, Yang Lin buried several gunpowder jars weighing ten kilograms at the foot of a small hill, although the lead of several meters long could burn for a minute or two, but he still didn't have the courage to light this thing himself, what if he didn't run far and fell? What if I twist my foot in a wrestling? Two hundred meters away, Li Er's anxiety, Yang Lin finally handed over the task of ignition to the lightly worked hard to urge Erfan.

"Your Majesty, the amount of gunpowder is a bit large, we must cover our ears and grow our mouths to release the impact of sound waves." While Yang Lin was explaining, he was demonstrating to everyone, and he saw a figure shooting here from a distance, which was the Qi Erfan who ignited the fuse.

"Boom."

If it is in the blue sky and white day, you must be able to see a small mushroom cloud, a few ten-kilogram gunpowder jars, this is the amount used to open the mountain and build the road, even if you cover your ears tightly according to Yanglin's instructions, the boss with his mouth open, can not escape the shock that can make people have a broken heart, it is a horse that is broken, not a person, of course, the head is like being hit by a big bell to urge Erfan's eyes are a little dazed, Yanglin taught people who are watching from a distance to cover their ears and open their mouths, but they forgot to teach this person who lit the fire, At the same time, they didn't take protective measures for the horses that pulled them here, and the people were fine, but they saw that the horses that were tied to the explosion point less than 100 meters suddenly fell to the ground with a whin.

A few seconds after the explosion, I heard the sound of broken stones and dirt falling from the air to the ground like raindrops, and the sound of banging lasted for almost a minute.

"Boundary."

Li Er, his three sons, and several eunuchs looked at the scene in front of them in disbelief, with such a powerful killing weapon, no matter how thick the city wall was, it was just a thicker piece of paper in front of gunpowder.
