War Sandbox: +54 for Environmental Simulation, +52 for Weather Forecast, +56 for Terrain Simulation

Just when Liu Yi was chatting with Yu Ban, the sand table was also completed, but at the moment of completion, Liu Yi was stunned, and he did not upgrade, but the experience points were more than half.

After entering the seventh level, unlike before, the attribute span is between forty and fifty-nine, and the experience required is one billion, Liu Yi has made the jade seal of the country over the years, built the new city of Yunnan, and includes the defense of Nanyang, the track of the entire Jingshu land, plus several disciples are also constantly doing, so far, it is also worthy of 500 million experience, when he did this sand table, it was just more than half, and what he obtained was only the improvement of the attributes, and there was no other gain.

"Mohou?" Yu Ban looked at Liu Yi, who was suddenly stunned, strangely, and called softly.

"Oh~" Liu Yi came back to his senses slightly, turned his head to look at Yu Ban and said, "What did Wen Zefang just say?" ”

It has been more than 20 years since he came to this world, and his heart has gradually become calm with the experience over the years, and now even if there is a change in the system, it only makes Liu Yi have too many surprises or other feelings.

"It's not early, Mo Hou Mo has to rest too late, and it's time for the last general to leave." Yu Ban glanced at the sand table strangely, not knowing if it was an illusion, he seemed to see the sky above the sand table just now, and there was fog that began to gather.

"Well, Wen Ze walks slowly." Liu Yi nodded, watched Yu Ban leave the grass shed, and looked at the sand table in front of him again, a trace of water vapor began to gather into a thin cloud, but if you don't look carefully, it is difficult to see clearly, after all, it is just a simulation, but the sand table in front of you feels like a small world, quite wonderful.

Liu Yi suddenly had an absurd thought, is the world in which human beings live also outside the world, and this world is made by an existence beyond human beings?

In the past, Liu Yi didn't believe in those things of God and Taoism, but at this moment, Liu Yi suddenly had some alternative views, in his previous life, he remembered that there was such a saying on the Internet, that cosmic civilization can be divided into seven levels, the first level can control all the energy on the planet, and can control various natural phenomena such as weather and geology at will, and then there are star civilizations, galaxy civilizations, and cosmic civilizations, and how to describe them, Liu Yi can't remember clearly, but it seems that when it comes to level six or seven, time and space can be controlled at will. Different universes can be created or destroyed at will......

At that time, Liu Yi was also very lively about this statement, but ...... What's going on with the system? Why did you suddenly come to this era that is nearly 2,000 years apart? Is it also the inheritance of a high-level civilization? But it seems that its own system has no other purpose than additional attributes.

Crossing is a very irresponsible word, when it doesn't happen to you, no one knows if it's really like this, but when it happens to you, you can't share it with others, but the thing of traveling through time or space, for human beings, even after two thousand years, is still an incredible thing, only in people's imagination.

This night, Liu Yi had insomnia, and all night, he was thinking about the meaning of life, which was originally a very meaningless thing, but this night, Liu Yi seriously thought about this question, even including why people live such esoteric and meaningless things.

The next morning, when he woke up, he didn't really have a pair of dark circles under his eyes, his physique was strong after all, and he had never really charged into battle in his life, let alone left any dark injuries, even if he was over forty years old now, he was still strong and healthy, and he didn't sleep all night, and it wouldn't have too much impact, but he was still in a state of confusion mentally.

"Mohou, it's better to rest for a day today, General Guan Ping's army is afraid that it will take three days to arrive." Yu Ban saw that Liu Yi was not in a good state and proposed.

"No, let's observe it again, the terrain of Yiyang and other places has not yet been understood, and this kind of thing is related to the lives of thousands of people, and there can be no sloppiness." Liu Yi shook his head, although the state is not very good, but today is not the day of war, there is no need to waste a day because of this, preparation is sometimes more important than the war itself, this point, Liu Yi has emphasized more than once whether he does it himself or when he teaches his apprenticeship.

……

Luoyang City, Si Li's Captain's Mansion, there are more troubles these days, Cao Xiu has not closed his eyes for three days, the Han army in Guanzhong has appeared three ways, and the news that 150,000 troops have left the customs shocked the government and the opposition, Jingzhou Guan Yu is even more powerful, Nanyang 70,000 troops poured out, Shu Han suddenly came out of 200,000 troops, all of a sudden, the world that had been peaceful for a long time seemed to fall back into the war-torn era.

In particular, Guan Yu, who was originally unhurried, suddenly accelerated the speed of the siege, and killed Yique Pass in an instant, and within one day, three urgent letters were sent from Yique Pass in a row, so that Cao Xiu, who originally wanted to see if the Han army still had a backhand, had to order to assemble troops to prepare to aid Yique Pass.

Yique Pass is an important checkpoint for guarding Nanyang this time, Cao Xiu has fully arranged 8,000 defenders in Yique Pass, coupled with the terrain that is easy to defend and difficult to attack, even if Guan Yu puts 70,000 troops over, it is impossible to capture it at once, not to mention that Guan Yu always has to pay attention to his own back road, right?

But judging from the emergency document of the Yique Pass guard, Guan Yu is not much, between thirty and fifty thousand, but the attack is extremely sharp, especially the siege equipment of the Han army, in one day, three times to attack the city tower, Yique Pass almost changed hands, the battle loss ratio is quite close, both sides are elite, this is almost unimaginable, this is not an ordinary earth city, it can already be regarded as a Xiongguan, the defenders are enough, a day was beaten like this, which made Cao Xiu very surprised.

"Quick, let General Niu Jin lead 5,000 soldiers and horses to gallop to aid Yique Pass, be sure to hold it, I will lead the army to arrive later!" Cao Xiu passed down the last military order, and asked the guards to urge Niu Jin, who had been sent to prepare for the army, to rush to Yique Pass as soon as possible to support.

As for the war in Guanzhong, Cao Zhen should be able to hold it for the time being, and the reinforcements of the imperial court should have moved at this time, as long as they can arrive, the situation in Guanzhong will not be too bad, but if the Han army can be blocked this time, next, Guanzhong should have some more soldiers and horses.

……

The sky has gradually darkened, outside the Yique Pass, Guan Yu looked at the Guancheng that was crumbling in the war, but had never been able to be breached, frowning slightly, Luoyang's reinforcements, I am afraid that they are coming soon, and even at this time they have arrived outside the pass, if they can't capture this Yique Pass, it will be difficult to break through it again.

"Zhou Cang!" Looking at the sky, Guan Yu's heart moved, and he summoned Zhou Cang.

"Prince!" Zhou Cang came to Guan Yu's side and intervened.

"You take a group of men and horses, take advantage of the fact that the siege is not over at this time, lie on the side of the mountain, wait for a while, after a certain Mingjin collects the troops, the three armies retreat, and the enemy army is slackened when the attack is slack, kill and capture the city!" Guan Yu looked at Zhou Cang and said in a deep voice.

This can be regarded as a kind of psychological warfare, after a day of fighting, seeing that the troops are collected here, the enemy's mind will inevitably be relaxed, especially when this battle is fought very hard, this mentality is more likely to appear, and at this time, it may become the last pressure to crush the enemy's resistance heart.

"Whoa!" When Zhou Cang heard this, he bowed down and was about to turn around and leave.

"Wait!" Guan Yu stopped Zhou Cang and said in a deep voice: "Bring a thousand school sword guards with you!" ”

The predecessor of the school sword guard was Guan Yu's five hundred school knife hands, each martial arts is exquisite, well-equipped, well-trained, is the most elite one in Guan Yu's hands, and acts as Guan Yu's personal guard on weekdays, but every time there is a tough battle, the school sword guard must be at the forefront.

Now Guan Yu is old, and his physical strength is not as good as before, but the school sword guard has expanded a lot, and the equipment used is also excellent equipment supervised by Liu Yi himself.

"Junhou, as soon as the school sword guard leaves, your safety ......" Zhou Cang naturally understands the importance of the school sword guard, and now that the Han army is pressing Yique Pass, Cao Jun can't even fight back, and it is only a matter of time before the city is broken, and such an enemy can't use the school sword guard to make a move.

"Who among the three armies can hurt me?" Guan Yu brushed the white beard under the remains and said proudly.

He has always been the only one who cuts others in the midst of thousands of troops, even if Lu Bu is resurrected and wants to provoke him Guan Yu in the midst of thousands of troops, Guan Yu will definitely teach him to be a man, and today's Han army is two concepts from before.

"Whoa!" Zhou Cang took a deep breath, agreed, turned around and left with the knife.

The war is still going on, the Han army is like an ant tide and continues to pass through the ladder and the well to kill the city pass, and the defenders fight together, and the defenders are constantly forced back through the numerical advantage, the entire Yique Pass, there are corpses everywhere, the strength of the defenders has been a little stretched after these two days of fighting, so that the way to drive the Han army down the city pass is unsustainable, Guan Yu brought 40,000 troops this time, and the defenders of Yique Pass are only 8,000, so fight, the first one who can't hold on must be Cao Jun, This is also the reason why the guard sent three emergency documents to Cao Xiu in a day, this time the Han army is fierce and abnormal!

The sky is getting darker and darker, and the torches have been lit in the Han army's formation, this day seems to be unusually long, and the Cao army defending the city is tense, just waiting for the sound of the Han army's gold to sound, they can take a breath.

When Guan Yu's crisp sound of gold echoed above Yique Pass, for the soldiers of the Cao army defending the city, this sound was nothing less than heaven!

Looking at the Han army that was rapidly receding like a tide, the general of the Cao army no longer had the heart to sigh at the well-trained Han army, he just wanted to take a good rest now, and by the way, he wrote an urgent document to Luoyang, but the sudden shouting of killing in his ears again made the breath that had just been relieved be brought up again......
