The induction of Yaya is also very strong within 10 meters, and it will weaken if it exceeds 10 meters, and it cannot be sensed beyond 15 meters. Mobile M.

Is all this because their qi and blood are connected and their qi and veins are connected?

It's not mentioned in "A Brief History of Martial Arts"!

The only explanation is that he has been holding Yaya and cultivating for too long, and the qi and blood of the two have been completely fused, and there is no difference, even if they are divided into two individuals, they can echo each other from afar and exchange with each other.

Although this matter sounded ridiculous, Lu Chao soon thought of the reasonableness in it.

According to the "A Brief History of Martial Arts", 'qi' is a kind of dark energy, which is different from the bones, nerves, and blood that really exist in the body.

Since it is a non-existent thing, it is not surprising that non-physical contact can echo each other and complete the process of operation.

The prerequisite, of course, is that the 'qi' in the two of them has been completely fused, and there is no difference.

No matter what the principle is, this is a great thing for Lu Chao.

In the past, Lu Chao always started some cultivation that required a large amount of 'qi' replenishment after Yaya fell asleep.

But he couldn't move too much, otherwise he would disturb Yaya's sleep.

Now there is no need to worry, whether Yaya is asleep or awake, as long as the distance between her and him is no more than ten meters, he can continue to cultivate.

I don't worry about the amplitude of the movement.

……

After coming out of the castle this time, Lu Chao adopted a new way of running and probing.

In the past, Lu Chao let Xiao Hei go into the woods to explore, in order to expand his search range as much as possible.

The last time he was robbed and ambushed by the road, he learned a lesson, so that he didn't dare to let Xiao Hei get too far away from him and Yaya. With Xiao Hei by his side, there is no way to expand the search area, but at least it can ensure that he can be warned in advance when there is danger.

As for exploring the surrounding woods, Lu Chao thought of a new way.

It was his elementary school physical education teacher...... No, the math teacher teaches the method.

If the tree is 10 meters tall and the mountain is 100 meters high, and the planet where the wilderness is located is about the same radius as the Earth, then if you climb the tree, you can see the mountain within a radius of 40 kilometers.

The simplified formula is basically 36 times the sum of the square roots of the two heights. Therefore, if the road is straight, you can climb the tree every 40 kilometers to see the circle, which can basically cover 30 kilometers of mountains on both sides of the road.

If the distribution of the mountains is not on the side of the road, you can only go into the woods for dozens of kilometers and then go up to the trees.

This is still visible to the naked eye, and if you use the high-magnification lens unscrewed from the sniper rifle, you can see even further.

If the radius of the planet where the wilderness is located is larger than that of the earth, Lu Chao can observe a larger range than the earth.

The way of going into the woods to find the mountains is time-consuming and laborious, and it is too time-consuming, and Lu Chao will definitely not use it. However, it is still possible to climb to the top of the tree every few tens of kilometers and observe the surroundings.

This may pass through the small buildings that appear in the woods, but if there are mountains within a few tens of kilometers on both sides of the concrete road, you can definitely spot them on a sunny day.

Lu Chao found a secret cave on the mountain he encountered in the first two times, the first time was a game adventure, and the second time he teleported and got the loot in the game adventure, and the harvest was very good.

If you can encounter a hill again, don't miss it easily.

……

The seventh day of departure from the castle.

In the evening, a particularly tall tree appeared on the side of the road, at least about twenty meters taller than the tree next to it.

Although in the morning and at noon, Lu Chao each carried out a tree climbing and observation, but after seeing this tree, Lu Chao couldn't help but climb it again.

The taller the tree, the farther you can see, and maybe you'll make some new discoveries this time.

This is also the twenty-first time that Lu Chao has climbed high and looked into the woods after coming out of the castle.

Three times a day is completely unnecessary, and mathematically speaking, once a day is almost enough to complete the observation task. But Lu Chao still couldn't help but climb high three times a day, and every time his heart was full of expectations, wanting to find something different in the woods, but he was disappointed in the first twenty times.

I wonder if I will continue to be disappointed this time.

In order to avoid Yaya getting lost on the ground when climbing the tree to observe, Lu Chao tied Yaya to his body every time he climbed the tree and took her to the top of the tree.

Yaya also likes the feeling of staying at the top of the tree and looking around.

This time was no exception, before Lu Chao climbed the tree, he tied the girl to his body with a waist stool, and then climbed up to the top of the tree.

The tree is 40 meters tall if you count the treetops, but it can only climb up to 30 meters in consideration of the weight of the father and daughter. However, even if it is only 30 meters, it is already beyond the height of the top of the other trees next to it, and you can see farther away.

Soon Lu Chao came to an observation height of thirty meters, and after sitting down on the branch, Lu Chao picked up the binoculars and looked around.

Woods.

Or the woods.

Just as Lu Chao was about to go down with some disappointment, Yaya suddenly stretched out her little hand, pointed to the southeast, and let out a 'Huh!' Hey! 'voice.

Yaya's performance generally means that she must have seen something different.

Lu Chao looked in the southeast direction, but he didn't find anything unusual.

In order to verify whether Yaya was pointing casually or really seeing something, Lu Chao picked up the high-powered mirror and looked at the southeast carefully.

This time, it really made him find something different.

Not a mountain, but a pit!

A crater that looks at least a few kilometers in diameter, if not larger!

The crater is also overgrown with trees, so it's hard to spot a crater unless you look closely.

Yaya's eyes are so good!

There will be buildings and adventures in the mountains in the woods, so there should be something different in this giant pit, right?

Lu Chao made a preliminary estimate that the giant crater was about twenty or thirty kilometers away from where he was now.

In order to avoid getting lost in the woods, Lu Chao decided to continue walking along the cement road for more than ten kilometers to reach the vertical point between the giant pit and the cement road, find a tree to climb up to confirm the location of the giant pit, and then go to the giant pit in a straight direction.

It's getting dark, and it's definitely not going to work today, so let's start early tomorrow morning.

For now, let's find a place to rest.

……

Wangshan ran a dead horse.

It's the same with looking at the pit.

The next day, as soon as it was dawn, Lu Chao set off, and in the afternoon arrived at the vertical angle between the cement road and the giant crater that he had discovered beforehand.
