"What for?"

Tai Shici, who was disguised as a hunter, walked more than ten steps to the Poyang City Gate when he was loudly questioned by the city gate guards, even if he was only carrying a bow and arrow.

Tai Shi Ci didn't plan to talk nonsense, raised the prey in his hand, and after indicating the identity of the hunter, he began to observe the layout of the soldiers guarding the gate, and then prepared to snatch a weapon and directly control the city gate.

In the absence of war horses, a military general is easily surrounded by hundreds of soldiers, so that even Tai Shici is certain to die, otherwise Dian Wei, who is known as evil, will not die in Wancheng.

However, there may be exceptions in the terrain of the city gate cave, which is why Tai Shi Ci decided to steal the city alone, but it is too difficult to stick to the spot for a tea time, but considering the actual situation, Tai Shi Ci still thinks that this is more reliable than building a ladder to storm the city before the enemy catches up......

Tai Shici's indifferent attitude towards the city gate guards made him feel offended, because no ordinary person dared to ignore him like this.

"Stop!" The guard drew his sword, ready to scare and scare this wild man who didn't know the height of the sky, and the dozen or so soldiers guarding the gate around him also cooperated and raised their spears and aimed at Tai Shici.

Tai Shi Ci ignored the guards, and his eyes were aimed at the nearest soldier, because the spear was more suitable for sealing the doorway than the Pu knife.

"How daring!" The guard, who was ignored again, shouted loudly, and angrily greeted Tai Shi Ci, but Tai Shi Ci just glanced at him, and began to prepare to make a move!

But it was because of this sight that Tai Shici suddenly saw an iron gate hanging on the city gate, and this discovery made his hair stand on end, and he was stunned for a moment and forgot to make a move on the spot, because this iron gate would make his plan go to waste!

The iron gate, commonly known as the jack gate, is a kind of defense facility that uses a winch to take off and land, and can be quickly put down in case of an emergency to block the enemy from the city gate.

The ancient Chinese liked to exaggerate the word, but the term jack gate is a bit humble, because its weight is more than 1,000 catties, of which the wooden iron-clad one weighs thousands of catties; There are more than 10,000 catties directly cast from pig iron.

Tai Shi Ci didn't expect that such a small broken county town would have such defensive facilities, so that there were quite two city gates to grab, which was an impossible task for Tai Shi Ci, who came alone.

Moreover, the winch that controls the jack gate is inside the city gate, and if Tai Shici wants to control it, he has to leave the city gate hole, which is easy to be surrounded......

"Enemy attack!" Just when Tai Shi Ci was stunned for a short time, an alarm bell suddenly sounded on the city gate, which startled the guards who wanted to come to trouble Tai Shi Ci.

"Not good!" Tai Shi Ci realized what was wrong, and he made an agreement with the Danyang soldiers hidden in the forest to charge towards the city gate when he saw him move, the sooner the better.

Now the city gate guards rushed towards him with weapons, and it was estimated that the fight had already started from a distance, so the Danyang soldiers began to attack, so they would naturally be discovered by the defenders on the city wall!

In this situation, it is impossible for strangers to be allowed to enter the city, and Tai Shi Ci has no choice......

The guard was startled when he heard the alarm, and he didn't care about making trouble with Tai Shi Ci anymore, so he turned around and was about to run into the city, but at this time, how could Tai Shi Ci let him run, killing this person, and the enemy army without command would be more conducive to his next actions.

So he no longer hesitated, and rushed forward with an arrow, grabbed the knife in his hand, and slashed down, and his head flew in an instant......

The guard is dying and hasn't figured out what's going on!

"Ahh Enemy attack under the city!! The enemy soldiers were startled by the sudden situation and subconsciously shouted for the police; Tai Shi Ci then took refuge and went up, and after slashing two people in a row, the enemy reacted and retreated to the city gate with screams!

Tai Shi Ci flew out with a knife, stabbed another person, grabbed the spear, and rushed in with him, cutting off the two gates behind him before the enemy soldiers even knew it!

At this time, if the enemy wants to close the city gate, I am afraid that he will have to pass over his body first.

According to the previous thought, at this time, Tai Shici's task has been half completed, and the rest is to hold the city gate for 10 minutes in the enemy's attack, and wait for the Danyang soldiers to rush over to respond.

Ether Shi Ci's martial arts, although there is no guarantee of success, there is still hope, at least if it fails, you can exit the city gate and do something else.

But now it's not going to work, there is one more jack gate, and there is no point in just guarding the city gate, so Tai Shici has to continue to assault forward, and he has to rush into the city to find the position of the winch that controls the jack gate, as for what to do next, he hasn't had time to think about it......

……

Wu County, Dantu County.

This night, Yuan Yao didn't sleep, waiting for the moment in the early hours of the morning, because today was the last day to systematically study the technology of "Compass......

In fact, Yuan Yao didn't have to wait at all, even if he wanted to choose the next technology to be studied, he could wait to wake up and do it, and it didn't have any impact at all, but he just couldn't sleep with excitement, because this was the first technology that the system had completed and Yuan Yao wanted to see it completed with his own eyes......

The moon and stars are scarce, and the night is low. Time is like water and ice, as if it were silent......

System prompt: Compass technology research is complete.

“……”

Yuan Yao was a little stunned, although he didn't expect any special effects after the completion of scientific and technological research, he still felt empty in his heart when he was so calm.

"Do you want to light the whole gunpowder to celebrate!" Yuan Yao laughed at himself for a moment, then calmed down and began to check the information after the "Compass" technology was activated......

Before the technology is studied, there is only a rough hint of information, and "Compass" only hints that it is possible to upgrade coastal facilities, build ocean-going seaports and sail ocean vessels.

Now, after completing his research, Yuan Yao has discovered some economic processes that have been activated along with the upgrading of coastal facilities, such as artificial pearl cultivation, bamboo planting oyster cultivation, and algae farming......

However, compared to these icing on the cake craft, there is one coastal facility that has attracted Yuan Yao's attention, and that is - the salt drying field.

Salt is one of the most important substances for human survival, and it can be said that it is the most indispensable in food, in addition to food and water; At the same time, it is also the most consumed food.

High consumption represents large demand; When the demand is large, it represents the benefit. Therefore, since Emperor Wu, the Han Dynasty has implemented the salt and iron official system, and the income from salt has also become one of the main financial revenues of the imperial court.

Even the size of the country can't help but be greedy, you can imagine how big the benefits of salt are!

The salt-making technology of the Han Dynasty was still the method of "frying" and "boiling", using a plate for frying and a pot for boiling, which is the so-called "boiling the sea for salt".

From the use of tools, you can imagine how poor the production efficiency of salt is at this time, and the salt drying plant is an epoch-making process to change this situation. And this process is now activated by the system's "Compass" technology!

Yuan Yao had a salt-making technology that was much higher than the output of this era, and Jiangdong still had a vast coastline, and seawater would become his inexhaustible wealth......
