The Invincible Overlord of Heroes

After studying with the scholar, Xu Lai could not rest immediately.

By the light in the bedroom, Xu Lai compiled the map drawn by the scouts during the day into the big map again.

He even took advantage of the darkness to use knotting and pacing to measure twice the overlap between the curve of Swan Lake and the obelisk map.

The knot is a fixed length that does not vary slightly like the pace.

After determining the number of knots, Xu Lai used a polished pebble to find the length of the lines on the obelisk map.

In this way, after a simple mathematical calculation, Xu Lai determined the actual proportion of the map and reality.

In this way, he doesn't even need to draw the complete map of the obelisk. As long as he determines the direction, he can reach any point on the map based on the length.

The center of the map is naturally included in it.

Thinking of this, Xu Lai even couldn't sleep, thinking about digging all night?

After all, it was still too dangerous at night, and Xu Lai was not sure whether there were wild monsters or other dangers entrenched near the center of the map.

At the center of the map, if you want to continue going all the way south, you have to pass through the territory of the group of manticores.

Of course he can easily avoid them during the day, but if the opponent's alert is triggered at night, he may not be able to defeat those manticores even with all his troops.

For the whole first half of the night, Xu Lai couldn't sleep well. The magic weapon Su Ya mentioned before was too tempting.

Xu Lai got up early in the morning, but unfortunately he was the last one. Su Ya got up early to prepare breakfast and arrange for the farmers to work.

Xu Lai brought the knots he made, his own archer troops and cavalry, as well as the militiamen and scouts.

Su Ya took the flying troops left by Xu Lai and her own troops to protect the safety of the village, and ate all the low-level wild monsters Xu Lai left behind.

There were no signs on the prairie, so it was no problem to follow the lines on the obelisk map at first. But when the obelisk map lost its usefulness, Xu Lai could only dismount and use knots to measure little by little.

There are two problems at this time. One is that a group of water elements appear in the middle and block the road.

Another problem is that even if he can measure it bit by bit, Xu Lai will not be able to maintain a straight line as the distance grows.

The water element is an elemental creature, immune to mental spells and water spells, but will withstand double fire damage. The initial level is level 3.

If it's just a water element, it's not a big deal, because this thing relies on its own big fish tail to swim. Not to mention its slow speed, it's still a melee unit.

However, there are several level 4 ice elements in this group of water elements, which can release low-level water spells. By default, they release ice arrows with a range of about 100 meters.

Xu Lai decided to kill these wild monsters without much thought. He could go around them, but with a distance of more than 200 meters, Xu Lai would not be able to maintain a straight line when going around them.

He has already thought of a way to overcome the straight line, which is to leave a soldier on the spot to guard. Without Xu Lai's order, these dull soldiers will never move.

Although this is not guaranteed to be straight, at least it will be roughly horizontal. At worst, he will have to dig a little more area. Anyway, he brought four militiamen.

150 meters away, Xu Lai took out his flame ray scroll and held it with one hand to complete his first spell cast.

In fact, considering the range of a marksman, these ice elements are not scary at all.

But Xu Lai was eager to experience the power of magic, so he tried it himself.

Xu Lai didn't feel much about the process of casting the spell. He didn't need to recite the spell or pose, he just needed to hold the magic scroll tightly in his hand.

The magic scroll will automatically extract the magic power from Xu Lai's body. Xu Lai can also clearly feel that part of the power in his body is being extracted, but this part of the power will not hinder his body.

After condensing for a full 1.5 seconds, a flame ray exactly like the Archmage shot out straight.

The flame ray shot by Xu Lai was also an order, and the sharpshooters and flame shooters behind raised their bows and arrows.

Ice element is an advanced unit of water element. It also inherits the properties of water element and can withstand double fire damage.

Xu Lai's flame ray happens to be a fire spell. This spell itself will not receive any bonus effects, but the damage amplification effect from the opponent can still be endured.

After deducting the effects of physical fitness and magic resistance, Xu Lai's flame ray dealt a full 300 points of damage.

The ice elements on the opposite side were no longer instantly killed, but directly shattered into pieces.

The flight speed of the flame rays was also much faster than the arrows. It was only when the ice element exploded and all the water elements stirred and swam towards Xu Lai that the arrows flying in the distance arrived.

The ice elements all fell to the ground under the first round of arrow attacks, so Xu Lai no longer had to worry about being attacked from a distance.

He stood calmly, waiting for the second round of arrows from the sharpshooters to cover him, and then waved his hands heavily.

24 nomads plus mercenaries and other cavalry all moved into action with a bang.

Even though there were only 30 cavalry in total, they ran with extraordinary momentum, splashing large swaths of mud.

However, neither the nomads nor the leader had charging skills, so the knights' servants and mercenaries did not charge either, and always maintained a similar speed.

Xu Lai also pulled the grassland horse and gradually accelerated to merge into the cavalry group. At this time, the water elements had just received the third round of blows, and their number had been reduced to single digits.

According to the newly acquired knowledge of knight's charge, Xu Lai, like the mercenaries, held a simple spear under his arm.

The spears of the nomads are shorter than those of the mercenaries, but there is no need to care about this length in the high-speed charge at this time.

The water elements were almost defenseless under the charge of the nomads, and were torn apart by the knights in just one encounter.

Xu Lai, who was at the front of the cavalry group, also successfully stabbed a water element.

15 points of strength plus 12 points of damage from the simple spear. After adding the speed bonus of high-speed charging, 20% of the physical attack of the intermediate offensive technique was added, which immediately caused a lot of damage to the water element.

It's a pity that the attributes are still a bit inferior after all. The most important thing is that the weapons are really poor. They use simple long guns on the same level as the first-level militia.

The water elemental was injured but survived, and was directly stabbed to death by a spear from the nomad behind Xu Lai.

After destroying this group of water elements, picking up all the dropped items, and taking away the black iron treasure box guarded by the water elements, Xu Lai didn't waste a moment.

Let all the nomads dismount and use them as a benchmark to keep measuring with knots.

After arriving at the intermediate node position he estimated, he returned to another 90 degrees, walked the previous distance, and stopped near a group of wild antelopes.

The antelopes were naturally not on Xu Lai's summary map. Apart from this group of antelopes, there was nothing around. There was no sign within hundreds of meters.

"Excavation!"
