The research institute is a building that Li Wenbin attaches the most importance to besides the barracks, and its function is very powerful. [with _ dream]ā

After the biomechanical technology is upgraded to Level 2, the function is also powerful, and it can already be used to create higher-level Level 2 mecha and engineering vehicles.

Level 2 mechs and engineering vehicles are far more powerful than Level 1, and of course, the cost and materials required are also rising.

——

Level 2 Battle Mech, Production Requirements: Energy 50,000, Level 2 Alloy 1,000 to 5,000 kg, Mutant Beast Carcass (Level 2 or above).

Second-level engineering mecha, production requirements: 50,000 energy, 2 tons of ordinary steel or 800 kg of first-class alloy, mutant beast corpses (more than 1 ton).

Second-level engineering vehicle, production demand: energy 50,000, ordinary steel 10 tons, mutant beast gene model.

——

The energy consumption of second-level mecha and engineering vehicles alone is ten times that of first-level mechas, not to mention the demand for other materials such as alloys and mutant beast corpses.

However, the high pay, the high return is naturally high.

Not to mention, a second-level battle mech alone is worth the ticket price.

The second-level battle mech, even if it is manufactured with the lowest material configuration, its combat power is equivalent to the middle of the second order, if it is configured with the highest material, its combat power can reach the peak of the second order!

Of course, for now, it was impossible for Li Wenbin to create the strongest second-order battle mecha, because he lacked an important material, the corpse of a mutant beast at the peak of the second order.

From the second metamorphosis of the earth to the present, the early stage of the second order is already the fastest level of evolved creatures, and there may be creatures in the middle of the second order or even above, but so far, Li Wenbin has not encountered it.

Therefore, the second-level battle mecha that he can make now has the highest comprehensive strength, which is equivalent to about the late second-order stage, which is produced by several fifth-star-level second-order early stage zombie corpses as materials.

In the past few days, Li Wenbin now has nearly 50 second-level combat mechs in his hands, of which 20 are upgraded from the previous first-level combat mechs, and the others are all newly made, which is very powerful.

In order to make these battle mechas, all of Li Wenbin's previous material stocks were consumed, and some of the remaining defective products were also used by him to make several engineering mechs and engineering vehicles.

Unlike combat mechas, the engineering mecha and engineering vehicles manufactured by Li Wenbin are only first-class and are not manufactured in accordance with second-class standards.

Because at this time period, the first-level engineering mecha and engineering vehicles are enough, no matter how high, it is a waste and not worth it.

Compared with biomechanical technology, another scientific and technological research of the institute is relatively inferior.

However, Li Wenbin still upgraded it to level 2, if not for anything else, just for that special function: biological transformation!

The first-level biological transformation can allow Zhan Weiguo, a half-limbed person, to directly cross several levels, soar to the late stage of the first order, and unexpectedly awaken successfully and become an evolutionary, which is not strong.

And the second-level biological transformation, once successful, the strength of the transformed person will directly reach the peak of the first order or even the second order, which is even more terrifying.

However, biomodification is uncertain and not 100% successful, so so far, there are less than 100 people in the entire Doomsday Fortress who are willing to accept the transformation and succeed.

Among these hundred people, Zhan Weiguo is the only one who has undergone two transformations, and now his strength is infinitely close to the early stage of the second order, and he is the strongest among all the biological transformations, and he is only one chance away from breaking through and truly entering the second order.

Biological modification is the hope of those ordinary or abolished people, even if the success rate is not guaranteed, even if they will have some mutant beast characteristics after success, it cannot stop them from squeezing their scalps and fighting for the impulse of a transformation place.

There is one thing that Li Wenbin has never mentioned and will not mention.

Once he accepts the biological transformation of the Doom Fortress, he will be marked by the Doom Fortress as belonging to Li Wenbin, and from then on, it can only be used by him.

This is not coercive oppression, but a hint from the soul, even if this person had boundless malice towards Li Wenbin before the transformation, once he is transformed, these malices will disappear, and in his place, he will be faithful to Li Wenbin without swerving until death.

In this regard, Li Wenbin remained silent and watched quietly.

In addition to the research institute, another thing that Li Wenbin remembers is the call of the barracks.

In addition to the cost of infrastructure construction and research institutes, Li Wenbin's large amount of energy has been invested in summoning troops.

In the past three days, except for the initial classes such as archers and spear and shield warriors, the number of other classes has increased considerably.

——

Farmer: 100

Blacksmith: 20

Cook: 20

Infantry: 400

Captain of the Infantry: 8

Archers: 10000

Archer Captain: 200

Spear and Shield Warriors: 10000

Spear Shield Warrior Captain: 200

Elemental Mages (wind, wood, water, fire, earth): 600 each

Elemental Mage Captain (Wind, Wood, Water, Fire, Earth): 6 each

Wolf Cavalry: 700

Captain of the Wolf Cavalry: 7

Shadow Assassin: 200

Captain of the Shadow Assassins: 4

Pastor: 50

Captain Priest: 2

Junior Commander: 10

——

Three days, seventy-two hours, more than four thousand minutes.

The third-level Doomsday Fortress can produce an elemental mage in an average of ten minutes, and in three days, a single elemental mage can summon a total of about four hundred people, and the five elemental systems add up to two thousand people.

Five hundred energy for an elemental mage, two thousand add up, and one million energy is spent.

The other main station of the army, the wolf cavalry, also increased by four hundred, and the total number reached seven hundred, which has formed a large cavalry scale.

As for the shadow assassins, priests, and those captain-level troops, Li Wenbin did not summon a large number of elemental mages and wolf cavalry like summoning them, but supplemented them according to the current number of troops.

In the end, it took about 1.5 million energy to summon these troops.

Coupled with the previous infrastructure and research institute upgrade costs, nearly 10 million yuan of energy was spent nearly half of it at once, which is more than all Li Wenbin's previous expenses combined, and it is really like a flowing cost.

The rest of the energy Li Wenbin naturally will not be wasted, according to the current situation in Wolf Smoke City, he bought a lot of items from the fortress mall that do not belong to earth technology, some are used for construction, and they are also consumed daily, and they are also needed for combat.

It can be said that Li Wenbin has tried his best to do everything he can think of, and exceeded the standard, and for a long time, except for summoning troops, there will be no need for him to continue to invest energy.

In the future, his main energy input will only be the summoning of troops and the production of battle mechs.

……

The beast spirit world, the doomsday fortress, the inner city, and the martial arts arena.

Li Wenbin is shirtless, wearing a pair of loose shorts, and is doing daily physical training.

Of course, in the eyes of many people, it seems that this system pervert is just a warm-up training, and in the eyes of many people, it is already an unimaginable hellish training.

A steel column, surrounded by one person, is three or four meters long and weighs more than three thousand kilograms.

This is Li Wenbin's warm-up tool, at the moment he is carrying a steel column, running, frog jumping and a series of muscle-stretching exercises.

He didn't use crystal power, he relied on it, just pure ** power.

Not far from him, Yun Meng and Wen Ruxue were also exercising.

Needless to say, Yun Meng naturally had been accustomed to this kind of training for her, and although it was a little difficult to deal with, it was not much of a problem.

It is like snow, because it has only recently started high-intensity physical training, and it is just an ordinary person, so it seems a little difficult.

However, she did not complain about being tired, and kept silently training according to the training plan formulated by Li Wenbin for herself, without any relaxation.

The three of them didn't communicate with each other, and they were all doing their own things seriously.

But......

Hey! ~

A childish coquettish drink broke the peace.

In addition to the three of them, there are two other figures in the martial arts arena.

One, it is the naughty and cute little girl Duoduo, at this time is tying up a pony step, practicing a set of simple boxing techniques at a glance, accompanied by every punch, and often will shout, very cute.

The other is Li Wenbin's first pet, the mutant Teddy - Da Bai!

This strange guy is learning the appearance of a little girl at this time, standing on his hind legs, and from time to time he comes to a dog's paw fist, and it looks like he is really a bit 'human-like and dog-like'.

"Whew~ I'm so tired!! ~”

After all, a child is a child, Duoduo immediately couldn't hold back after hitting several sets of boxing techniques in a row, and as soon as he gave it away, his little butt sat on the ground.

She shook her little hands, her little face was red, and she was humming there.

Dabai on the side was very eye-catching, and after the little girl stopped, it also sat on the ground, sticking out its big tongue, looking like 'I'm also tired'.

This guy has now evolved to the late stage of the first order, and he will soon break through, and his strength is very strong.

However, with the increase in strength, this guy's greedy character has not only not changed, but has intensified, looking at it, it seems that he intends to evolve towards the 'full-time cute pet', and to sell cuteness and stupidity to support himself.

"Big white, let's go, let's go play eagle and catch chicken~~"

After a little rest, Duoduo skillfully climbed on Da Bai's back, sat on the 'dog saddle' specially built for her by Li Wenbin, and with a wave of her little hand, she drove Da Bai out of the martial arts arena.

Training? That's just a hobby for Lady Duoduo, and her real job is to play carefree and happy.

Li Wenbin and the three of them silently looked at the two guys who left, and did not react.

This is the Beast Spirit Realm, and in this, no one can hurt Duoduo.

Don't look at Duoduo, there is only one big white who sells cuteness for a living, and thinks she is a soft persimmon. As long as someone dares to fight Duoduo's idea, before they have time to do it, they will be sent to hell for penance by the dagger of the Shadow Assassin Captain.

Training, going on.
