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

One by one, the big trees fell, turning into bare trunks, and Lu Chao erected them one by one in the earth pits dug with shovels around the house.

Compared with the first time he built a wooden wall, Lu Chao's efficiency is obviously much higher now.

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

As for his internal strength, it should have reached more than 60 points by now, because he can blast out more than 60 concussive punches in a row without Yaya infusing internal force.

A large increase in physique 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.

While cutting down trees with his fists, a fallen tree attracted Lu Chao's attention.

It is the fruit of this tree.

He remembered very clearly that Xu Junshan had this kind of fruit in his mobile phone.

This kind of fruit will not only be very toxic when eaten, but also the smoke burned after drying is even more toxic, which can release some kind of nerve paralyzing gas, and inhaling one bite will lead to a soft coma throughout the body, and inhaling multiple mouthfuls will even die.

Once you are in 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 spend an hour or two to let the body detoxify itself.

In other words, after inhaling the poisonous smoke of this fruit, it will take at least one or two hours or more to wake up.

Lu Chao estimated that the ashes he saw in the trap near Xu Junshan's house were the fruits of this kind of tree, which were ignited by Xu Junshan and thrown into the pit.

Once someone falls into the trap dug by Xu Junshan, they will be worried about their lives if they unconsciously inhale this smoke.

Lu Chao found five or six dried fruits on this tree, soaked them in the resin he had collected to absorb the oil, and carefully wrapped them in the plastic bag he found for storage, maybe they would 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 courtyard in front of the house.

As for traps and the like, Lu Chao didn't plan to get them.

He wasn't prepared to stay here for too long.

Even if it is a wooden wall, it is not deliberately built, it is just a by-product of the cultivation of "Concussion Fist".

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

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

If this trend continues, the river will soon run out of fish to catch.

Fortunately, Lu Chao still has a certain reserve, if the fish in the river are really cut off, Lu Chao can only go on the road again.

Don't worry too much about the water, since the snow melted last time, there are many small ponds in the lowlands of the woods, and even if the weather is cold and frozen, you can use firewood to melt the ice into water.

After hitting the road again, if he finds a richer source of food and a more suitable stronghold, Lu Chao will abandon this stronghold.

During this period of time, after being able to eat enough meat every day, Lu Chao felt that the efficiency of his cultivation seemed to have improved a lot compared to before. After all, the nutritional value of bear meat and fish meat is much higher than that of the fruit on the tree.

Every day passed, Xiao Hei spent a little longer awake than the day before.

When Lu Chao was free, he studied the pet training textbooks, so he did some training for Xiao Hei according to the gourd scoop.

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

After the dog whistle is adjusted, it will make a sound that cannot be heard by humans, but dogs are very sensitive, and the pet dog will run to the owner after hearing it.

The dog whistle can also be used as a prop for training pet dogs, and different actions can be completed according to different long sounds.

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

And Xiao Hei's performance is much smarter than that of ordinary pet dogs, and some of the training in the textbook that lasts for a week or even a month, Xiao Hei often only trains for one or two days to have an effect.

Especially when Yaya played with the dog whistle, she learned the long sound that Lu Chao blew, and was trained by Lu Chao to call Xiao Hei, after training, no matter how far Xiao Hei was from Yaya, as long as Yaya blew the whistle, Xiao Hei would rush to it.

Once Lu Chao and Yaya went out early, Xiao Hei was still in a coma, but Lu Chao let go of the binding on his body.

Yaya inadvertently blew a dog whistle by the river two kilometers away, and a few minutes later, Xiao Hei came galloping in.

Later, another time, Lu Chao deliberately threw Xiao Hei, who was about to wake up, into a certain place in the woods, and then went to another place in the woods two kilometers away from Xiao Hei, and it was a place that Xiao Hei had never been to before.

Yaya blew the dog whistle, and a few minutes later, Xiao Hei also galloped in!

Lu Chao deeply suspected that Xiao Hei's sense of hearing and smell had been greatly strengthened after swallowing the black bear's crystal nucleus, otherwise it would be impossible to hear the dog whistle two kilometers away.

In addition to training to find the master, Lu Chao also used dog whistles of different lengths and rhythms to train Xiao Hei to advance, retreat, lie down, escape, and even attack the target according to the methods in the textbook.

……

Another half a month has passed.

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

Xiao Hei's waking time every day has also been extended to seven or eight hours.

It never rained again in the woods, and there was no snow.

The temperature is still very low.

In the past half a month, the river has become shallower and shallower, and there are fewer and fewer fish in the river, until the river is so small that it cannot flow, and it is completely frozen and cut off, and Xiao Hei and Yaya have not been able to catch any more fish.

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

Without the fish, it looks like we have to find a new stronghold again.

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

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

This means that those fish should live in the south.

Based on experience on Earth, it seems like the south side should be a little warmer.

Of course, this experience may not be applicable here.

Lu Chao was hesitant whether he should go upstream of the riverbed to find the source of those fish, or continue along the cement road east to see where the two vans came from.

This is indeed a very tangled question.
