After Lin Tian bought this bloodthirsty sword, he still had crystals worth more than 10,000 yuan left, and he did not look at them in this weapon and equipment store.

I can't afford it anymore if I like it anymore. The weapons here are more expensive than I expected.

[Developing an atomic bomb].

Lin Tian walked on the dirt road in the camp street and tried to upgrade to the intermediate level of the [laboratory] skill. Can he create weapons of mass destruction of the earth's civilization?

[Dingdong, R&D failed, the selected R&D and manufacturing item level is too much higher than your current level, and it is impossible to develop and manufacture.]

【Develop Gatling heavy machine gun】,

【Dingdong, R&D failed…】

【Developing AK rifles】,

[Dingdong, it takes 1000 hours to develop an AK rifle, and 1000 hours to manufacture an AK. Required materials: ore*0.1 unit, wood*0.1 unit, crystal: red level 1 crystal*1, with one hundred bullets. Have you started research and development? Yes/No.]

When Lin Tian was about to give up, the [Intermediate Laboratory Level 1] skill actually prompted that AK can be developed this time.

The weapon of Earth's technological civilization can finally be built in this continent of gods and demons.

However, seeing the research and development time, Lin Tian became a little weak.

1000 hours of research and development, and 1 AK can be produced in 1000 hours.

After AK is created, the six days of the demon attacking the camp will be over.

I now have more than one red level 1 crystal. Even if I invest in the research and development process, I will not be much faster to build the AK rifle.

Moreover, the power of the AK rifle is not as powerful as the magical feather arrows emitted by the indigenous female archers of the God and Demon Continent.

At least a Gatling machine gun or something is useful.

However, this is also a good start.

At least it can develop and manufacture weapons to the earth's civilization.

Lin Tian is preparing to give it a try. After his level is improved, will the R&D and manufacturing speed increase accordingly?

AK rifles may have relatively complex structures and are slow in R&D and manufacturing.

【Develop remote control start C4 explosive pack.】

Lin Tian tried to make something simple.

[Dingdong, R&D and develop a remote control start C4 explosive package, which takes 5 hours to make a remote control C4 explosive for 1 hour. Required materials: ore * 0.1 unit, wood * 0.1 unit, crystal: white 3-level crystal * 1, whether to carry out research and development and manufacturing, yes / no.]

Lin Tian was a little looking forward to this prompt.

[Research and development of remote control C4 explosive package], Lin Tian immediately chose to develop it.

This C4 explosive pack is cheap, and the research and development and manufacturing speed is relatively fast, so you can accept this speed yourself.

I just don’t know how powerful the C4 explosive pack I made.

Make several remotely controlled C4 explosive packs, blow up zombies and demons, and they should be able to kill them.

Let’s talk about research and development first.

Lin Tian decided to buy some ore and wood. On the street, he found an indigenous aunt and asked.

Just find a warehouse selling ore and timber.

Lin Tian bought some directly.

Ores and wood are much cheaper in this camp than what you eat.

One whiteboard level 1 crystal can be exchanged for 1 unit, that is, a few pieces of ore and a large bale of wood.

Lin Tian directly bought 10 units of ore and 10 units of wood, and placed it in his own storage space, which only took up two units.

I originally wanted to give it a try, the synthesis box of everything, but agreed with the camp leader Ilaina that the time to build a high-end crystal crossbow rattle was almost here.

Let’s build a crossbow rattle, Wanhe synthesis box, and then try it later.

Now I haven't thought about what to synthesize with this synthesis box of everything.

Walk quickly towards the east exit of the camp.

On the way, Lin Tian opened a chat group at the Earth Arrival Camp to see if there is any new news for other compatriots on Earth.

However, as soon as the chat group opened, I found that the atmosphere inside was not right, and the morale of the people who came to Earth was now depressed.

【The battle last night is so good, so many people died, I want to go home】

[I want to go to work, but I don’t want to protect the camp and fight monsters or demons. This battle is really dead!]

[I saw the indigenous people in the camp in the morning and used straw mat covers. The wooden carts were pulled outside the camp and burned them. A large number of corpses were thrown into the pit and burned together. If they died, there would be no ashes or graves!]

[There are six nights left. Can we keep it? I don’t want to die!]

[Come to the camp and help transport stones and build a wall. Build a stone wall and don’t let demons and monsters enter tonight. We have a greater hope of survival!]

[Why are we so unlucky? Are the camps they go to are safe when they are reincarnated and descended to the Gods and Demons Continents? Our cursed camp is attacked by demons when we come up!]

[Hey, I've only been level 3, and I've been level 3 Fireball Technique, but I can't buy it in the camp!]

[I am even more miserable. I chose the shooter profession and I can't shoot accurately! Fortunately, in the current stage of the demon attack camp, I provide free feather arrows, otherwise I will not be able to afford feather arrows!]

【I miss my wife, I want to go home!】

[I miss my daughter, I'm here, and after kindergarten, no one picks her up.]

[I want to go take a shower, and I want to go back too, and I beg for a way to go back.]

...

Lin Tian looked at the chat group of the Earth Arrivals, and now it is a miserable conference!

Now the starving demon cursed the earth's arrival in the camp. After the battle last night, death was by their side.

Many people on earth are afraid, especially the six nights of demon attacking the camp.

Even the Aboriginals have no confidence in whether they can keep this camp, let alone them.

Lin Tian has closed this chat group and will not watch it for now.

My upgrade speed and equipment are pretty good now. Thanks to my arrival, I woke up from the gift package of novice.

When I left with the fat thief uncle Jeter, Lin Tian also tried to inquire.

In fact, the talent of awakening by the advent of the earth is not given by the divine priest.

This talent is hidden in the bloodline and soul of the earthlings.

This god priest from the God and Demon Continent is just giving some help to awaken the talents hidden in the human body on earth.

Fat uncle Jeter had asked before, whether Lin Tian was awakened or not.

Lin Tian shook his head with a smile.

This time retrospective talent also has weaknesses. If outsiders know the specific effect of their time retrospective talent, they will easily be captured and imprisoned alive.

Lin Tian decided to go back to his talent at this time, and no one told him, just know.

When we arrived at the east exit of the camp, thousands of people were carrying stones at the edge of the camp.

The indigenous female archers wearing leather jackets and short skirts were carrying the bows and arrows behind them. Under the scorching sun, they worked hard to carry large stones, sweating, and still had no rest.

The Earth's arrivals and the elderly and children in this camp are also involved in the construction of the stone wall.

After a piece of stone wall was cleared, there was a senior indigenous wizard who released earth magic and strengthened the stone wall.
Chapter completed!
