Originally, he Xiang Yu wanted to take everyone to respect Liu Bang as the new co-master, but considering that he was not effective in protecting him, he could only be demoted to the new King of Qi, and Liu Bang also said that it was okay to be wronged, after all, everyone is for the people of the world.

At this point, Liu Bang, the king of Qi, officially took office, and thanked the overlord for his benevolence and righteousness, and swore that he would have fun if he said something that he didn't believe in ghosts.

And Sima Xin's territory was given to Xiang Yu's brother-in-law Yu Ziqi.

.........

In Shuzhong, the court of Qin, everyone has learned the news of Xiong Xin's death and the news that Liu Bang was named the king of Qi, and everyone agreed that at this time, the six kingdoms of Shandong must be unstable and the princes are moving.

This is a good opportunity for Daqin to subdue the world.

Li Feng agreed.

Xiong Xin's death successfully made Xiang Yu feel at ease, and he heard that he was preparing for a big wedding with Yu Ji in Pengcheng recently, so he didn't want to pay attention to other things at all.

At the beginning, he promised Yu Ji to follow him, and he should repay him with the world, but now that his dream has come true, he is full of spirit, Xiang Yu's whole person is about to float, and he is staying in Pengcheng to enjoy the pleasure of waking up to the power of the world and drunk on the knees of beautiful women.

Even if Fan Zeng repeatedly advised him to continue to conquer the world, Xu Tu was enterprising, but Xiang Yu couldn't listen to it.

Sometimes, when a man is romantic, it is enough to embarrass the world.

Liu Bang is very enterprising, but the overall situation is still solid, and he has no suitable opportunity to forge ahead.

But he is not idle, on the one hand, he is indeed seriously governing the people of Qi and winning the hearts of the people, on the other hand, he is recruiting troops and horses, and he is ready to make a move at any time.

Since seeing the power of that fierce fire oil tank in Shuzhong, Liu Bang has been working hard to remember, and he is also secretly looking for this artifact, so that when the storm rises again in the future, he can achieve unexpected results on the battlefield.

In short, they don't have time to deal with Li Feng now.

This just gave Li Feng time to develop.

Of course, these are only auxiliary roles for Li Feng, and his greater confidence still comes from himself.

The Qin family came with good news, the first season of hybrid rice has matured, according to Li Feng's reasonable breeding, under the reasonable fertilization, the yield per mu has really reached more than 2,000 catties, and is currently preparing to plant the second season.

"Set aside some of them for storehouses to keep aside, and distribute the rest to the people who have good land, and cultivate them in the name of royal gifts, and in the future they will be taxed thirty times." Suppressing his joy, Li Feng repaired the book to Qin Dan overnight, of course, it is also necessary to properly express his longing for Qin Yu.

Not long after, Qin Dan replied: "Obey the holy order, the people of Bashu will be grateful for Your Majesty's kindness, and in addition, Yu'er misses Your Majesty's prosperity, and I wish Your Majesty to be happy as soon as possible to comfort your feelings." ”

..........

Now, the grain and grass are ready to start a war that will last for months.

The weapons and equipment of the Ordnance Bureau have also produced results, and they can be put into use with only Li Feng's order.

The new army has been trained, and the army of 80,000 tigers and wolves is waiting to enter Guanzhong, recapture the territory of Qin, and reunite with their fathers and elders in their hometown.

To be honest, in this era that is still in the middle of cold weapons, the 80,000 army wants to attack Sanqin, which has an army of more than 200,000, which is a bit hanging.

Especially now that Sanqin has been prepared, it is no longer possible for him to be like Han Xin in history, and come up with a surprise attack strategy of "Ming Xiu Plank Road and Secretly Crossing Chen Cang".

This means that the 80,000 army needs to rely on hard power to attack, and he does not want to flood the ruins like Han Xin in the original historical time and space, which will cause a large number of civilian casualties, which is not advisable.

In fact, Li Feng has never understood the ancient behavior of flooding the city with water or slaughtering the city at every turn.

In this way, the common people are dead, there are no people to exploit you, no soldiers, no money, even if you get this city, there is a fart.

Even if you are a tyrant, defeat the defenders, break into the city, take its wealth and goods, and collect its beauties, isn't it fragrant? But if you're done killing, how will you collect it?

On the school field outside the Ordnance Bureau, Li Feng was testing his new weapon.

It's all epoch-making stuff, and it's one of his chips.

Originally, what Li Feng gave was just a drawing, and then added a little explanation, but he didn't expect that Meng Rui's people were so creative that they actually got these things out.

Trebuchet, a conventional artifact in siege warfare, is generally used at this time by the human trebuchet handed down from the Warring States period, using a lever to let people pull hard and throw stone projectiles.

The firing range can reach about 170 meters, and it can throw 30 kilograms of heavy objects, but it takes more than 20 people to operate a stone throwing machine, the rate of fire is slow, and the manpower requirements are relatively high.

After improvement, Li Feng creatively invented the winch and made a torsion stone thrower.

Manpower was replaced with a winch rope, the range averaged 250 meters, only 4 people were needed to operate, and it could launch up to 50 kg of weight.

After improving the trebuchet, in order to achieve better results, Li Feng improved the cannonballs on the basis of oil as raw material and combined with the siege concept of the Ming Dynasty.

Thermal weapons such as mortars, bazookas, and arquebuses cannot be made.

Li Feng tried, but the result was for unknown reasons, but if there was a hint of a hot weapon, something would definitely happen immediately the next day, either the armory exploded or the production staff died suddenly.

Weapons are also often inexplicably turned into parts status.

Maybe this is the so-called ban on heat weapons, power and the like in the system, but Li Feng is not too depressed, to be honest, he has a bit of a B number, even if these things are not forbidden, he doesn't know how to get them.

Since thermal weapons can't be built, some simple, practical and immoral things are still okay.

For example, some sharp weapons that surpass the Qin and Han dynasties, as a history lover, he has not seen much of the information of these things.

The poisonous dragon breathes fire god tubes, borrowed from the Ming Dynasty, which is the earliest smoke screen and poison gas bombs.

Make a large bamboo tube, which is filled with oil, plus lime, grass and trees, cow dung wolf fire, mugwort, arsenic, realgar, stone yellow, soaphorn, ginger powder, knotweed, pepper, sand oil and other medicines, mixed together.

Since these things are not as heavy as stones, they can be very large in size and can contain a lot of things.

After igniting it, it was placed on a trebuchet and fired, and the poisonous gas penetrated into the enemy's seven orifices, and the people in the city could not open their eyes at all, and they had to endure the discomfort of poisoning. At this time, take the opportunity to attack the city and get twice the result with half the effort.

In order to achieve the greatest lethality and shocking effect, Li Feng also made the eight-bull crossbow that could only appear in the Song Dynasty come out in advance. This thing can definitely be regarded as the most lethal weapon with the greatest impact on the human body throughout the ages, and there is no one, even the current big sniper cannot be compared.
