This world is not as peaceful as it looks. Monsters attack the camp every night. If there is not enough defense, these monsters will rush into the camp, destroy the base camp, and cause the game to fail.

Although Zhang Tuohai is powerful, he is not afraid of wild beasts, and can protect the safety of the base camp, but those monsters will bypass him to attack npcs, destroy various production machinery, and consciously slow down his development pace. Several of his automatic logging machines were smashed by a few grizzlies, causing his development to lag behind and the game to fail.

Zhang Tuohai hung the trolley loaded with the Gatling machine gun behind the command vehicle, tied it with a traction rope, and continued to drive forward.

Along the way, Zhang Tuohai picked up five small cars loaded with Gatling machine guns and a small excavator.

After taking back the scattered vehicles, Zhang Tuohai did not leave immediately, but drove towards a big tree.

This tree looks ordinary, but it is actually a wonder.

This tree can produce 40 different fruits every day. If it is transplanted into the camp, it will increase the happiness of the residents in the camp, reduce the needs of the residents, improve combat effectiveness and scientific research capabilities, and reduce the time required for scientific research in the camp.

It is a perfect buff provider. If you can't bring it back on the first day, it will be gradually damaged in the next few days of monster siege, and finally completely destroyed.

This was something Zhang Tuohai couldn't bear, so after he landed and completed the initial construction work, he came out to look for this tree.

Seeing that the tree was still intact, Zhang Tuohai heaved a sigh of relief, drove the small excavator hanging on the rear of the car, and started digging towards the big tree.

He has already dug hundreds of times, he knows the texture of every inch of soil in this area, he knows the position of every big rock, and he dug a big tree out of the ground without hindrance. out.

Then, Zhang Tuohai activated the small hook machine behind the excavator to hoist the big tree.

"Go!"

Zhang Tuohai jumped into the command vehicle and pulled a lot of things back into the valley.

At this time, several automatic sawmills in the valley had collected the wood needed to upgrade the base camp.

Zhang Tuohai chose to build two carpentry workshops, and clicked to upgrade the base camp.

A ball of white light enveloped the sunshade made of palm leaves, and a light green progress bar appeared in front of Zhang Tuohai. There was no time on it, but Zhang Tuohai, who had experienced thousands of simulations, knew that it was 30 seconds.

Thirty seconds passed quickly, and the awning originally made of palm leaves turned into a vacation cabin made of wooden boards, which looked much stronger.

[The upgrade of the base camp is completed: the current level is lv2, unlock the stone technology, unlock the wall, foundation, catapult, sentry tower... 200 units of stone are required for the next level. 】

Zhang Tuohai looked at the stone materials and found that they were not enough to build and upgrade, so he built two refugee camps, and ten refugees came out of them.

The refugees stood respectfully in front of Zhang Tuohai, waiting for his order.

"Go build a fence, build one at the mouth of the canyon, and dig a trench in front of the fence."

"By the way, dig a hole here and plant this salad tree in."

Seeing the huge salad tree, the eyes of the ten refugees lit up.

They are all tool people described by the program. After seeing the strange resource, their morale instantly increased by 2 points.

Soon a big hole was dug, and the salad tree was carefully planted in the hole by ten refugees.

Taking advantage of this opportunity, Zhang Tuohai placed five Gatling machine guns in various positions of the camp.

Three Gatling guns crossed the canyon, locking the passage.

The remaining two were placed closer to the coast.

At night, not only will there be animal hordes attacking on land, but there will also be dangers coming at sea.

After setting up Gatling, the refugees took tools from the carpenter's workshop to build fences and trenches, while Zhang Tuohai rushed out of the camp in a command vehicle.

After leaving the valley, Zhang Tuohai looked left and right, took out the compass to confirm the direction, and then turned the steering wheel to drive towards the distance.

After driving for about an hour, Zhang Tuohai crossed the vast grassland and came to the edge of the forest.

A few touches of red cloth and a tall wooden fence can be seen far away from the edge of the woods.

Several people dressed in animal skins, armed with spears, bows and arrows, and with red paint on their faces came out of the woods and stopped Zhang Tuohai.

"Don't be afraid, I come with peace and kindness, this is my gift."

As Zhang Tuohai said, he threw a pig hind leg that had been prepared earlier out of the car, and threw it at the feet of several people.

Several people glanced at each other, one of them bent down cautiously, touched the smooth pig hind legs, his face showed shock, the red and white pork texture exudes a charming smell, they all glanced at each other, A man carried the pig's hind legs and ran quickly towards the village.

Zhang Tuohai didn't take it seriously either, he leisurely got out of the car, leaned against the car door and waited.

After a while, there was a sound of footsteps in the village, and an old man in a red robe and holding a long stick appeared in front of him.

"Hello, I am the elder here, do you need any help?"

"I am a traveler, passing by here unintentionally, this is my little heart, please accept my kindness and friendship."

As Zhang Tuohai said, he pulled out another piece of red silk from the car, and handed it to the old man with both hands.

The old man took the silk and satin hesitantly, and then a shocked expression appeared on his face.

"There is such a smooth cloth in the world, it is as smooth as milk, it is a gift from God."

"I don't know if this thing can prove my friendship?" Zhang Tuohai asked with a smile.

"Of course, of course, if you can present such a precious gift, we will naturally not doubt your sincerity."

The old man handed the silk and satin to a confidant beside him with both hands, and then solemnly took out a black sheepskin scroll from his arms.

"We Mosha people will never disappoint our friends. This is the secret technique of our village. It is a witness of our friendship. Please accept it."

Zhang Tuohai took the sheepskin scroll with both hands, and at the same time, a line of prompts popped up.
