The sentry scouts and righteous officers of the Silla army were reported that none of the sentry scouts sent to the front to explore the road returned, so they were vigilant and ordered the whole army to move slowly. Pen @ fun @ pavilion wWw. ｂｉｑUｇE。 ｉｎｆｏ

Previously, the sentry cavalry was attacked by the Tang cavalry, and only two of them returned alive, but when the Silla army rushed to the location where the Tang army was discovered, it was long gone.

The Silla generals once thought that the Tang army was afraid of their army and fled without a fight, but now it seems that they must have gone back to ask for help.

"Report, General, the Silla Army is slowing down."

Hei Tooth Changzhi tore off a piece of cooked beef, chewed it twice in his mouth, and swallowed it, sneering, "It seems that the Silla people have discovered us." He shouted to the generals who were waiting for the order: "Order the whole army to immediately mount their horses and prepare for battle." ”

"Whoa."

The generals returned to their armies and reorganized their troops and horses, and the more than 7,000 cavalrymen who were resting on the ground packed up and stepped onto their horses.

Seeing that the armies were ready, the blacktooth Changzhi waved his right hand, and the soldiers moved slowly with their horses and whips, and then controlled their mounts to speed up and gallop wildly.

Seven thousand five hundred people rode wildly, 30,000 iron hooves nailed to the horseshoe kept stepping on the road they were traveling, the deafening sound of horses' hooves spread for miles, the birds in the bushes were frightened and fled, and the people in the mountains and wilderness hurriedly packed up their belongings and took their wives and children to the deep mountains and dense forests.

The officers and men of the Silla Army, who were slowly advancing several miles away, were so distraught by the deafening sound of horses' hooves that they stopped moving, clenching their weapons in their hands and feeling uneasy.

"The Tang Army is here." The ministers' faces were grim, and their eyes were fixed on the large group of cavalry that appeared in front of them.

The righteous officer chuckled: "There are quite a few people coming, and they all look like cavalry." ”

"Array." The ministers changed their grim complexions, their eyes were fierce and tenacious, and they shouted at the troops who were still in a state of march, and ordered the adjutant general to lead 3,000 cavalry to stand by in the rear of the formation.

"The pikemen are in front, and the attackers are in the back......"

In the face of the vigorous slaughter of the Tang cavalry, the Silla infantry was in a panic under the loud reprimand of the officer, and arranged in an orderly formation from the outside to the inside to deal with the cavalry attack.

"Ho ......" Silla army poles and spears were erected in front of the formation, and the archers stood behind, and the arrows were drawn to fill the bowstring under the command of the officers.

"Shoot."

A thousand Silla archers fired a volley at the Tang army that rushed towards them, and then quickly mounted the arrows and fired again, wave after wave of arrows formed a rain of loose arrows in the air, arcing in the air, and the arrows swished down towards the rapidly rushing Tang cavalry group.

The Don cavalry was equipped with a round mounted shield, which hung on the left side of the saddle.

Seeing the Silla arrows flying in, the charging Tang soldiers hurriedly took off their riding shields from their saddles, held them in their left hands to protect their heads, and bowed their bodies slightly forward, trying to prevent the arrows from hitting their torsos under the cover of the riding shields.

The arrows came with a whooshing sound, and in the blink of an eye, one or two arrows were inserted into the shields in the hands of the Tang soldiers.

The lucky soldier dodged the flying arrow, and the unfortunate one who was caught in the reins of his horse tightened at the first moment of the arrow, and fell to the ground with the neighing of his mount.

But more soldiers dodged the arrows, but their unprotected mounts were a few arrows shorter, and in the mournful sound of the horses, the galloping horses fell to the ground violently, and the soldiers on the horse's back were thrown out with strong inertia. It's good to fall into a dog and gnaw mud, but unfortunately, it falls into a dog's gnaw, and when you support your aching body with both hands, you look up and see the war horse rushing up behind you instantly trampling yourself to death on the ground, and after all the cavalry rushes over, there is a mess of rotten meat left.

The Tang cavalry, who rushed ahead, took their bows or crossbows from their saddles and counterattacked with arrows, and suddenly thousands of crossbow arrows with powerful penetrating power flew towards the Silla army.

The Silla pikemen, who were in the front row without shield protection, were suddenly shot dead and wounded by hundreds, so that the formation was unstable.

At this time, the Tang army rushed to the front of the Silla formation, and the Silla pikemen in the front line faced the Tang cavalry surging with Zhangba horse lances, everyone was frightened, and the formation retreated involuntarily, and the war horses did not hesitate to crash into the Silla army formation under the control of the master.

The pikemen in front of the Silla army failed to withstand the Tang cavalry rushing to the front, and the formation lined up was scattered by the Tang army, and suddenly people turned over on their horses, the mourning of the war horses and the screams of the soldiers before they died, and the desperate fighting of the soldiers on both sides who rushed together resounded throughout the mountains and forests.

Relying on his skillful equestrian skills, Blacktooth Tsuneyuki split the arrows that shot at him in the charge, and took the lead in crashing into the Silla army with a horse lance.

In the days that followed, Li Yu would pick up the "Guide to Geography" whenever he had time to study it. The book is divided into eight volumes, the first of which is a general theoretical overview, expounding Ptolemy's system of geography and revising Marinus's cartographic method. Volumes 2 to 7 contain a list of 8,100 locations on Europe, Asia, and Africa, and use the latitude and longitude network established by Hipparchus, dividing the circumference into 360 parts, and indicating the latitude and longitude coordinates for each location. Volume 8 consists of 27 maps of the world and 26 maps of local areas.

In his book, Ptolemy argued that geography was a linear description of the entire known area of the earth and everything related to it, that is, drawing graphs and replacing geographical descriptions with place names and surveying lists. In his Guide to Geography, he used a smaller value of the circumference of the earth measured by Bosidonis, which made Li Yu completely unimprinted, and he couldn't help but think that the circumference of the earth could be measured at that time. Hundreds of years ago, the Romans went as far east as Persia, and having heard of the Malay Peninsula and the Silk Kingdom (i.e., China) could not determine the distance between the two. To the west to know the farthest point Ptolemy himself speaks of in his book as the Canary Islands, and to one of its westernmost islands as the prime meridian of longitude. According to the memories of previous lives and the impressions of the map, the prime meridian is set at the Greene Site Observatory in the United Kingdom, and the longitude of this Canary Islands is obviously not far from the 0 degree longitude of the Greene Site Observatory in the United Kingdom.

After comparing the latitude and longitude of the list of 8,100 locations on Europe, Asia, and Africa listed in volumes 2 to 7 of the book, and the longitude and latitude of these familiar places in my memory, it is found that the latitude gap between Alexandria, Rome, Jerusalem and other historical cities where Ptolemy lived is not too large, but the longitude gap is inevitably too large, and Li Yu estimates that at least the difference with the actual longitude is more than ten degrees.

What is even more unbelievable is that the distance of the sea indicated in the book is really speechless, the distance of the sea is much smaller than it actually is, look at the map of the world drawn by Ptolemy, and extend the land to the east. Think of the inhabited world as a continuous mass of land surrounded by ocean basins. For example, the three continents of Europe, Asia and Africa seem to be close together, those small ocean basins mark the Mediterranean Sea and the Caspian Sea in the Black Sea, the Indian Ocean is much smaller, and Asia is too close to Europe. More than 800 years later, Columbus was deceived by his map into thinking that he could reach the East by sailing westward, and as a result, he discovered America by mistake. And he showed on the map: there is still an unknown southern continent in the south of the Indian Ocean, but the fact is that there is no southern continent at all, only the smallest Australian continent and the three islands of New Zealand and Tasmania, and then to the south, the frozen Antarctica can be counted as the southern continent, Li Yu couldn't help but laugh at the mistakes in the book.
