Lu Chen drew an artillery airship, and then drew a steam engine structure diagram, he didn't know much about the internal structure, and Lu Chen, who was not professional, made up a lot of brains, and then muskets, grenades, and even drew a bazooka. These things Lu Chen is drawing and playing, but he is not just painting and playing, at least the artillery and bombs he really plans to do in the future, and after he has gunpowder, he began to think about it. However, because he was going to come to the rescue of Gongsun Zhan, he put it on hold for the time being, and Lu Chen was even more idle now than when he was in Yanmen Hanoi, so he drew what he had thought about and made some preparations for the future.

Trains, planes, tanks, aircraft carriers or something, don't think about it in this life, it's even difficult to get a musket. Lu Chen didn't want to develop high technology, although it sounds very relieving to drive a tank to crush Cao Cao, but this is impossible after all, Lu Chen is still a very realistic person, he will not be ambitious.

But he also knew that some simple inventions and innovations could be realized, and could improve his military strength and the productivity of the people, so of course he was happy to do it. For example, in addition to bombing the city wall, bombs can also be used to build roads, if you want to get rich first to build roads, in addition, it can also be used for mining, Lu Chen's location is very good, he will not let go of the treasure land of the rampant coal production in the future, coal must be dug.

These days, Lu Chen has nothing to do, so he thinks a lot, mostly some small inventions, and he has no experience in politics, so he can only start from science and technology and find ways to improve his soft power.

I thought a lot, and I drew a lot, of course, it was very rough, not only a matter of painting level, but also a problem of not using a brush. For this reason, Lu Chen also tried to make a quill pen, but unfortunately, it was not as easy to use as written in the novel, often scratching the paper or dripping a large lump of ink, or the little wolf was more reliable.

For Lu Chen's paintings, Pang Tong said that he couldn't understand it, even if Lu Chen patiently explained it to him, he couldn't understand what kind of blasting propulsion, mechanical leverage, Pang Tong listened to the mosquito coils all over his eyes. Especially when it comes to hot air balloons and airships, Pang Tong doesn't believe that thing can fly into the sky, and quotes scriptures to say that the wooden bird built by Lu Ban back then can fly to the sky, how can your round ball-like thing fly? Don't you see that birds have wings? Have you ever seen a pig fly?

Lu Chen argued with him for a long time, and found that he couldn't say it clearly, so he made a Kong Ming lantern out of the remaining paper, made a frame with bamboo strips, and asked the blacksmith to make a wire through the lower part, and a piece of rag stained with tung oil was wrapped in the center of the wire, and then, the Kong Ming lantern flew into the blue sky decisively.

Pang Tong was suddenly surprised, he could imagine that this lamp could really carry people up hundreds of times larger.

However, in addition to being shocked, Pang Tong said that he was very puzzled: "Why do you want to call Kong Ming lantern?" It has something to do with Zhuge Villager? ”

Since hearing the word Zhuge Villager in Lu Chen's mouth, Pang Tong's name for Zhuge Liang has changed, sometimes it is Zhuge Villager, and when he grits his teeth, he is Zhuge Pifu.

Of course, Kong Ming Lantern has something to do with Zhuge Kong Ming.

"Uh......" Lu Chen remembered that he had just said that he had leaked his mouth, and Pang Tong and Zhuge Liang did not deal with it, so he said nonsense, "I'm not talking about Kong Ming lanterns, but empty lights, lights that emit bright light in the air, referred to as empty lights." Hey, since you have witnessed its lift-off, this lamp will be called Shiyuan Lantern in the future! ”

Lu Chen did not hesitate to transfer Zhuge Liang's patent to Pang Tong. Pang Tong was flattered and liked it very much, looking at the "Shiyuan Lantern" that was flying higher and higher, and said: "Xiao Junhou, can the Shiyuan Lantern fly to the fairy world?" ”

Sou.

The feather arrows have been coming through the air.

Smack.

The Shiyuan lamp was shot through and then fell.

"Faerie...... It seems impossible. ”

Lu Chen squinted at it, and saw Cao Xing's goods holding a bow, and he shrank in the distance with a few personal soldiers in high spirits, pointing at the air, and could vaguely hear sycophant words such as good archery and marksman.

When Cao Xuan and the others saw Lu Chen and Pang Tong, they ran over, with a black face, and shouted: "Xiao Junhou, just now I found out that someone was using witchcraft on our military camp, and there was a fiery and bright thing flying in the air, and the soldiers were all shocked, but they were not afraid, and they shot it down with a bow and arrows. Someone has been sent to arrest him now! I think someone wants to use the art of fire attack on us, this is a demon art, don't be careless, Xiao Junhou! ”

Black art?

Hex: Your sister!

Lu Chen snorted and said to Cao Xing: "Demon magic...... You've read too many fantasy novels! Then he cursed and walked away. What an expensive piece of paper, he was ruined by this fool (he didn't feel that he was also wasting paper), and Lao Tzu's masterpiece!

Pang Tong looked at Cao Xuan and said, "The demon art is waiting for Xiaojun to release." After speaking, he glanced at Cao Xing with disdain, and also left.

Cao Xuan scratched his head and screamed strangely: "It turns out that Xiao Junhou really learned demon art from the old immortal?" No wonder it's so powerful. ”

Back to the tent, Lu Chen continued to write and paint, although Pang Tong didn't understand, but after seeing the wonder of Shiyuan lantern, he also watched with interest, of course, his eyes were still mosquito coils, and they were rotating mosquito coils.

Lu Chen doesn't like painting or "design", but Gongsun Xu is too fumbling, it's been five days, and he hasn't pulled it out, Lu Chen muttered a lot about whether Gongsun Chan was his father or not.

Actually, Gongsun Chan is really Gongsun Xu's father. Gongsun continued not to go south immediately, not because he was not in a hurry, but because he couldn't. On the other hand, he had less than 10,000 men in his hands, and his strength was so weak that he did not dare to venture south. He needed to wait for Zhang Yan's army to arrive, and then go to Yi Jing together, however, Zhang Yanjun's speed was too slow.

The reason why Zhang Yan is slow is not because the soldiers are slow, but because of the institutional characteristics of the Yellow Turban Army in Montenegro, which makes their reaction speed and action not fast. The Yellow Turban Army has always been a plate of loose sand, Zhang Jiao was fine before he died, and as soon as Zhang Jiao died, the Yellow Turban Army was completely dispersed. So it was quickly exterminated, Zhang Yan's methods were not bad, and he not only survived Yuan Shao's many encirclements and suppressions, but also collected the yellow scarves in Changshan, Leping, Julu and other places, and his strength continued to grow. However, Zhang Yan's subordinates usually have their own side and have to give short notice when mobilizing, and the efficiency of the promotion is very low.

After another two days, the Yellow Turban Army was finally coming.

Zhang Yan sent his son Zhang Fang to lead 5,000 cavalry to Guangyang to find Gongsun Xu, and "escorted" them south to Yijing to join his army. Of course, the escort is just talking, it is a statement to take care of the face, although Gongsun Xu has few soldiers and horses, but there is no problem with his own safety, Zhang Fang is here to ask for food and money, and the escort is quite euphemistic.

Now, Gongsun Xu had no choice but to fully agree to Zhang Fang's request and did not dare to refute it at all. Under the concession of Gongsun Xu, the grain and grass baggage were also negotiated, and they could finally start to go south.

Lu Chen just drew some of the things he needed, and even drew a few Ultraman pictures out of boredom, he originally wanted to draw Mr. Aoi, but he didn't have enough skills, so he gave up. The paintings were properly collected by Lu Zhan, and then, Lu Chen received a notice to go south, and his mood suddenly improved a lot.
