After returning to the new stronghold, Lu Chao took Xiao Hei and Yaya to fish every day, and then continued to practice shock punches in the woods around the house.

Big trees fell down and turned into bare trunks, which were arranged one by one by one by one by Lu Chao in the dirt pits dug with shovels around the house.

Compared with the first time when building wooden walls, Lu Chao is now significantly more efficient.

Without the Dimension Supermarket, Lu Chao didn't know how much his current physique had reached, but he estimated that he might have exceeded the limit of 150 points of humanity.

As for his internal strength, it should have reached more than 60 points now, because without Yaya's internal strength injecting it, he can shoot out more than 60 shock punches in a row.

A significant increase in physical fitness also means a significant increase in strength. Whether it is cutting down trees or building wooden walls, the efficiency will undoubtedly be much higher than before.

When cutting down the tree with his fist, a fallen tree attracted Lu Chao's attention.

It's the fruit on this tree.

He clearly remembered that this kind of fruit was found in Xu Junshan’s mobile phone.

Not only will this kind of fruit be very toxic when eaten, but the smoke burned after being dried is even more amazingly toxic. It can release a certain kind of nerve paralysis gas. Inhaling one mouthful will cause the whole body to become soft and coma, and inhaling multiple mouthfuls may even die.

Once you get poisoned and fall into a coma, you can still use drugs to detoxify in the real world, but in the woods, you can only lie in the air circulation, and it takes one or two hours to detoxify yourself.

In other words, after inhaling the poisonous smoke from this fruit, you will have to be in a coma for at least one hour or even longer before you wake up.

Lu Chao guessed that the ashes he saw in the trap near Xu Junshan's house were the fruits of this kind of tree. They were ignited by Xu Junshan and threw them into the pit.

Once someone falls into the trap dug by Xu Junshan, he will unconsciously inhale this smoke and will have life worries.

Lu Chao found five or six dried fruits in this tree. After soaking them in the resin he collected and sucking oil, he carefully wrapped them in the plastic bag he found and stored them. Maybe it will come in handy in the future.

Three days later, Lu Chao built a complete wooden wall around the house in the new stronghold, creating a large yard in front of the house.

As for traps and other things, Lu Chao doesn't plan to do it.

He was not going to stay here for too long.

Even the wooden wall is not deliberately built, it is just a by-product of practicing "Shocking Fist".

During these three days, the water in the river became shallower and fewer fish.

Especially today, Xiao Hei and Yaya only caught five fish in the morning, which was much less than the previous few days.

If this trend continues, there will be no fish in the river soon.

Fortunately, Lu Chao still has some reserves. If the fish in the river are really cut off, Lu Chao will have to go on the road again.

As for the water problem, don’t worry too much. After the snow melted last time, many small ponds appeared in the lowlands in the woods. Even if it was cold and ice, you could use firewood to make the ice into water.

After setting off again, if you find a richer food source and a more suitable stronghold, Lu Chao will give up this stronghold.

During these days, I was able to eat enough food every day, and after eating meat, Lu Chao felt that his cultivation efficiency seemed to have improved a lot compared to before. After all, the nutritional value of bear meat and fish is much higher than that of the fruits on the trees.

Every day passed, Xiao Hei had been awake for a little longer than the previous day.

When Lu Chao was idle, he studied the pet training materials and then performed some training on Xiao Hei according to his own interpretation.

The main tool is the dog whistle, ultrasonic dog training whistle.

After the dog whistle is adjusted, it will make a sound that humans cannot hear, but dogs are very sensitive. After hearing it, the pet dog will run over to find the owner.

Dog whistle can also be used as props for training pet dogs, and different movements can be completed according to the sound of different lengths.

Although Xiao Hei is a wolf, after Lu Chao's experiment, he found that various training methods for dogs in the textbooks are also effective for Xiao Hei.

Moreover, Xiao Hei's performance is much smarter than that of ordinary pet dogs. In the textbooks, some training sessions last for a week or even a month, Xiao Hei often only trains for one day and has an effect in two days.

Especially when Yaya was playing with the dog whistle, she learned the long sounds that Lu Chao blew, and was trained by Lu Chao to call Xiao Hei. After training, no matter how far Xiao Hei is from Yaya, as long as Yaya blows the whistle, Xiao Hei will rush to come.

Once, Lu Chao and Yaya went out early, and Xiao Hei was still in a drowsy sleep, but Lu Chao let go of his body.

Yaya accidentally blew a dog whistle by the river two kilometers away. A few minutes later, Xiao Hei rushed over.

Later, there was another time when Lu Chao intentionally threw Xiao Hei, who was about to wake up, into a certain place in the forest, and then went to another place in the forest, two kilometers away from Xiao Hei, with Yaya, which was a place that Xiao Hei had never been to before.

Yaya blew a dog whistle, and a few minutes later, Xiao Hei also rushed over!

Lu Chao deeply suspected that Xiao Hei's hearing and smell were greatly enhanced after swallowing the black bear crystal core, otherwise it would be impossible to hear the dog whistle two kilometers away.

In addition to training to find the master, Lu Chao also trained Xiao Hei to advance, retreat, lie down, escape, and even attack targets according to the methods in the textbook.

...

Another half month has passed.

Lu Chao's training on Xiao Hei was very effective.

Xiao Hei's daily awakening time has been extended to seven or eight hours.

There has been no rain or snow in the woods.

The temperature is still very low.

In the past half a month, the river water became shallower and there were fewer and fewer fish in the river water. Until the river water was so small that it could not flow and completely frozen and broke the flow, Xiao Hei and Yaya were unable to catch the fish again.

Fortunately, Lu Chao had reserved a lot of dried fish before, and even if he didn't find a new source of meat, it would be enough for the whole family to eat for at least half a month.

Without fish, it seems that we have to look for a new stronghold again.

When continuing to explore in which direction, Lu Chao hesitated a little.

The river flows from the south to the north, and the fish swim upstream along the river.

This means that those fish should live in the south.

Based on experience on Earth, the south side should seem to be warmer.

Of course, this experience may not be applicable here.

What Lu Chao hesitated now was whether he should walk up the riverbed to find the source of the fish, or continue to go east along the cement road to see where the two vans came from.

This is indeed a very tangled issue.
