After coming out of the wormhole, Qin Haohan saw the changes in the gymnasium.

The velocity insects and worker bees guarding here surrounded the circle to defend the mother.

The Fang sisters hugged in a corner and looked at the huge monster with some anxiety.

The second-level mother, Pan Heng, was on the side of the basketball court of the gymnasium, like an ancient giant beast crawling there.

The insect limbs that were originally just in the prototype have grown out, each one is as thick as a tree trunk, and there are as many as nine on one side.

The eighteen insect limbs on both sides are slightly bent, and they can support their huge body to stand up at any time.

The upper and lower jaws form an acute angle, with a long upper jaw and a short lower jaw.

The upper jaw spits out like a rain eaves, and there is a deep black hole below which is the mouth of the mother's corpse and the gate.

It is about fifteen meters long, four meters tall, and seven meters wide.

The tail occupies about five meters in length, but the tail is not much thinner than the body. I don’t know what role such a huge tail will have in the future.

Unlike ordinary first-level Zergs, they are born white, with the color of the mother's body black and bright in black.

Although the skin still looks sticky, it is much better than before, and it feels that its defense has improved.

After seeing Qin Haohan come in, the mother's eighteen insect limbs exerted force and stood up with a loud bang!

Boom! Boom!

Step forward.

The speed is slow, almost the same as walking alone.

After many experiences and lessons, Qin Haohan certainly knew what this guy was going to do. He should be licking himself with his tongue and immediately issued an order: "Stop! Leave down!"

When the mother heard this, she immediately crawled down.

Qin Haohan smiled, thanks to his intelligence, otherwise he would have been licked again.

Walking over, he reached out and patted the mother's huge head: "So good."

The mother was praised by the master and immediately stuck out her tongue excitedly.

"Suck!"

Have you ever seen a tongue bigger than a human?

Qin Haohan, who had just taken a shower in the morning and changed into a new sportswear, had mucus flowing down his body.

"I.....!"

Qin Haohan wiped his face with his hands, and he was really overwhelmed by this kind of ceremony.

Hurry into the mother's house and change clothes, and check the situation after the mother's house is upgraded.

The system light curtain lights up.

"Second-level Zerg mother: weighs 22 tons, moves at 10 kilometers per hour, cannot run or fly, has low combat ability, has three insect eggs per day, and can hatch existing non-hero units for free."

"Unlock the main building of Zerg, the thorn snake nest."

"Unlock Zerg auxiliary buildings, scientific research cavity."

"Unlock Zerg auxiliary buildings, modulation rooms."

Several consecutive tips introduce the approximate situation after the mother's upgrade.

Qin Haohan quickly changed his clothes and asked him how much he said.

"Why aren't the Zerg's new combat units unlocked?"

"Drug, under normal circumstances, the new main combat arm of the Zerg second-level mother is the prickly snake. If you want to produce prickly snakes, you must first build the prickly snake nest. When the prick wants to develop more new Zerg units, I suggest you build a scientific research cavity immediately. After the scientific research cavity is completed, there will be more options for scientific research insects. These Zergs can help you quickly develop new Zerg, which is a must for the growth of our tribe."

Qin Haohan checked the cost of the building.

Snake nest: cost 1,000 food, 500 oil mine.

Modulation room: cost 2,000 food, 1,000 oil ore, 500 gas ore.

Scientific research institute: cost 3,000 food, 1,500 oil ore, 1,000 gas ore.

Qin Haohan originally thought that the nests of the main combat troops should be the most expensive, but he did not expect that the scientific research cavity and modulation chamber were much more expensive than the snake nest.

You know, he has not been idle for a while and has only plundered more than a thousand gas mines.

As for food and oil mines, it is not enough, so they can only be built selectively.

"Why is scientific research accent so expensive?"

"Science and technology are the primary productive forces."

Qin Haohan nodded, saying that he was indeed good, so it is natural that there is a reason for it to be expensive.

But he asked again: "How can the mother be upgraded to level 3?"

"Master, upgrading to level 3 at level 2 is much more difficult than upgrading to level 1 at level 2. Please check the mother's upgrade standards."

It is indeed difficult for Qin Haohan to find the upgrade standards for mothers.

First of all, metal.

It requires 10 tons of iron, one ton of aluminum, one ton of copper, and 100 kilograms of silver.

Iron, aluminum and copper are not too difficult to make, and the difficulty of 100 kilograms of silver is not small.

It seems that I will go to places like jewelry stores to collect more food in the future.

Metals are the first condition, and the second condition is scientific research.

Qin Haohan's scientific research agenda was required to develop two new Zergs.

Level 1 upgrade to level 2 is one, and this time there are two.

Then there is the third item.

The number of Zergs under his command is required to exceed 2,000.

Qin Haohan felt that it was not too difficult. As long as the Zerg had resources, the violent soldiers would be in minutes.

Of course, to complete these, you must build all the thorn snake nests, modulation rooms, etc.

He knew about the snake's nest and scientific research cavity. This was the first time I saw this modulation room.

“What is a modulation room?”

"Master, the modulation room is a very important construction unit of our tribe. Whenever the mother is upgraded, the Zerg level produced will automatically increase. For example, now that the mother is upgraded to level 2, all the Zergs produced will automatically be of level 2. The Zergs produced before need to enter the modulation room for modulation. The first level can be modulated to level 2. If they reach level 2 after combat, they can be modulated to level 3."

Qin Haohan's eyes suddenly lit up. This thing is so good!

Now under his command, Xiaotian is at level 3, Xiaobai is at level 3, and there are many second-level units. If modulated, the combat power will be improved by no means a little bit.

This time, the raid in the Seven Star Arrow Hall would have been much more difficult to solve if it weren’t for the power of Xiaotian and the Golden Head Electric Centipede.

Qin Haohan actually really wanted to start working on the spot and build these buildings immediately.

But he couldn't do this. The end of the world had begun for almost ten days. He had no news about his sister yet, so he could not continue to stay in Snow City.

The second-level mother's research and development has been completed, and it is time to leave Xuecheng and head to Sanjiang.

But he still started construction.

Even if you can't place it first, it's okay to make it first. When you arrive in Sanjiang, you can place the buildings built by science and technology directly without waiting.

The construction of the snake nest takes 12 hours, the modulation room takes 48 hours, and the construction of the scientific research chamber takes 72 hours, which is as time-consuming as upgrading the motherboard.

Qin Haohan's resources were not enough to produce all the resources, and the construction of buildings also needed to be done one by one, and several could not be built at the same time.

He chose the scientific research agenda that took the most time. The building took three days and was built on the road. He waited for the new base to be found before placing it.

"It takes 72 hours to build a scientific research chamber, which consumes 3,000 food, 1,500 oil ore, and 1,000 gas ore. Please wait patiently."

After deducting resources, Qin Haohan has become a little poor.

At this time, a wave came from the wormhole outside, and the Zerg at the Seven Star Arrow Hall was back.

Qin Haohan walked out and saw that the injured Zerg had recovered a lot.

It should be that in the Seven Star Arrow Hall, the Zerg's regeneration ability is difficult for any race to match.

Wang Yuan and Han Dong also came back, with seven or eight people behind him, both men and women.

It seems that some people chose to leave, and Qin Haohan didn't care. At present, there are almost enough of these seven or eight people working.

"Boss Qin, Li Luyao and Cao Nan have already resolved." This is what Wang Yuan reported.

Although Wang Yuan was honest in front of Qin Haohan, he was actually a ruthless person, otherwise he would not have been sent by Lu Dachuan to trade with Li Heng.

Qin Haohan nodded: "Is it okay for you?"

When I often read forums, Qin Haohan still knows that Lu Dachuan is currently making great progress in Xuecheng and is a capable person.

Wang Yuan's face was a little embarrassed: "You can't say it's okay. Lu Dachuan talked to one of us and already knew the situation here. He even scolded you on the forum."

As he said that, Wang Yuan handed over his cell phone.

Qin Haohan took it and saw that Lu Dachuan's swearing post had been topped.
