Before lunch, Xia Ling hurried back to Wuhun City with the Titan.

Old Jack also led his farming team to work in the fields behind the Papal Hill.

There is only a kitten left in the house, and a little rabbit who comes to eat.

Originally, the Titan was a little embarrassed to come to the Summer Ling family for dinner.

But by the time he actually took the first bite, he couldn't stop his mouth at all.

After eating and drinking, the Titan slumped into his chair rubbing his round belly.

"Teacher, your cook is too good, if you can eat this delicious food every day, I can give you a day job."

Zhu Zhuqing and Xiao Wu laughed on the side without saying a word.

Another man who has been conquered by good food.

After eating, Xia Ling personally took the Titan to the Martial Soul Research Institute hidden in the deep mountains and old forests outside Martial Spirit City.

"Teacher, where is the research institute you are talking about? I didn't see anything. ”

The Titans looked around, seeing only forests and mountains.

"Follow me."

Summer Spirit led the Titan to an unremarkable mountain and pulled out a communication card.

"Hello? Guard, please open Gate One. ”

"Roger, Your Highness the Holy Son, Gate No. 1 is opening."

The guards responded quickly from inside the billboard.

The communication cards are all in pairs, and those who are qualified to enter the Martial Soul Research Institute have a corresponding communication card, and there are detailed records of entry and exit.

Their materials are all kept in the guardhouse.

As long as the communication rings, the guards on duty can directly know who is requesting to enter, and the confidentiality is extremely strong.

Although ordinary researchers do not have soul power and spiritual power, they can activate the vibration function by pasting the jade plaque on a recognition area on the door.

At that time, the guards inside the door will take the initiative to activate the corresponding jade plate and contact the other party to verify their identity.

After activation, the jade plate can directly conduct sound, and no other operation is required.

The construction of this research institute in the mountains had already begun a long time ago, even earlier than the Martial Spirit Arena.

Xia Ling, who was "doted" by the two giants of Bibi Dong and Qiandaoliu, was given a high degree of autonomy by the two of them.

As long as you don't do anything out of the ordinary, you will basically be satisfied.

What's more, every time Xia Ling made any big moves, he would also give a very detailed plan for the elders to see.

Therefore, the construction of the Wuhun Hall Wuhun Research Institute was not hindered in any way, and it successfully received a lot of support.

Now it has been built and is waiting for the owner to move in.

Most of the top blacksmiths in the Martial Spirit Hall have moved their work to the research institute.

There was a slight rumbling vibration from the seemingly ordinary mountain rocks, and the sound was not loud.

A gate slowly opened on the mountain.

After the two entered, the door closed silently, as if nothing had happened.

Upon entering the Institute, the Titan was shocked by what shocked him.

Judging from the fluctuation of soul power coming from the two guards when they just entered the door, the two of them were at least Contra level powerhouses, and they were very strong.

There are also several soul saints lined up on both sides, ready to go.

The momentum that came from the two Contras was not even inferior to his own.

A powerhouse of this level is to be offered up in other kingdoms and principalities, and now he is looking at the gate here?

What the Titans didn't know was that not only were the guards here Contra and Soul Saint, but there were also Super Douluo all year round.

It was none other than the ninety-eight-level Second Enshrinement, Golden Crocodile Douluo.

Originally, the offering would not leave the temple unless there were special circumstances.

But Xia Ling had a good personal relationship with Golden Crocodile Douluo, and gave Golden Crocodile Douluo some small help in terms of cultivation.

Feeling the hope of breaking through the limit Douluo, coupled with the acquiescence of Qiandaoliu, this matter was so logical.

Passing through the currently empty first-floor hall, the staircase at the far end spreads downward.

The only sound in the passage illuminated by the soul guide lamp was the sound of the two of them marching.

The long and narrow passage can effectively prevent large-scale invasion.

If there are really a large number of soul masters who break in regardless of life or death, the Demon Modified Tang Sect secret weapon hidden above the passage will teach them to be human.

What is the forty-eight consecutive Zhuge God crossbow?

Twenty combinations, four hundred and eighty consecutive rounds of giant enhanced version of the Zhuge Divine Crossbow?

Anyway, it's a fixed weapon, but you can reload it for me!

Big is good!

More is beauty!

However, these Titans of the Mechanism hidden in the shadows can't feel it.

He was now stroking the concrete wall, his face shocked.

"Teacher, what kind of stone is this wall made of? Why is it so smooth and delicate? It's even stronger than the old rhinoceros's walls! And I can feel that the wall seems to be a whole piece? ”

"It's not stone, it's called cement, it's a new building material that I've created. This material is characterized by ......"

Xia Ling was aroused by the Titan with an occupational disease, and began to explain to him the composition of the Martial Spirit Research Institute.

The production of cement is actually not difficult, the raw materials are nothing more than limestone, sand, iron powder, etc., which are all available in the Douluo Continent.

It doesn't matter if the blender or heater is not there, you can use the soul master instead.

The production speed of the soul master is even faster than that of the machine.

After exchanging the mature cement recipe with the system, Xia Ling had already made the craftsmen of the Martial Spirit Hall produce a lot.

However, a large amount of cement produced in recent years has been used to build the Martial Spirit Research Institute.

The Martial Soul Research Institute is built on the mountain as a whole, and the caves that originally existed in the mountain are hollowed out.

A large amount of cement was poured so that the strength of the buildings in this mountain was comparable to that of the strategic mountain fortress in the previous life, and it was difficult for Title Douluo to pose a threat to it.

If it can really be harmful, just let Golden Crocodile Douluo come out and kill him, and directly solve the problem from the root.

Through the narrow hallways and several large spirit-forged metal gates, the two of them finally reached the true interior of the research institute.

"This way, I'll take you to the forging area."

The vast majority of the areas within the Martial Spirit Research Institute have not yet been activated, and only some members of the forging area have already settled in.

Hundreds of blacksmiths are in full swing.

Thanks to some of the black technologies of Douluo Continent.

Otherwise, not to mention hundreds of people forging together, it is the ventilation in this martial soul research institute that will be a problem.

Summer Spirit didn't make a big fuss, just whispered to the Titan about one facility after another.

The further he walked inside, feeling the heat and the clanging of metal, the more excited the Titans became.

One after another light rose up, which was a sign of the completion of a thousand forgings.

This place is simply amazing!

There are so many excellent colleagues!

There are also forging equipment that is more powerful than the casting room of their power clan, which is simply heaven.

As early as several years ago, when Xia Ling figured out the method of a hundred forgings, he had already taught all these skills to the blacksmiths of the Martial Spirit Palace.

It is not difficult to forge, and after trying for a while, everyone found that the superiority of forging is much stronger than casting, so they have changed their banners.

Some time ago, when Ling returned to Wuhun City in the summer, he compiled his previous forging experience and Tang Wulin's forging experience into a book and handed it to many blacksmiths.

After more than half a year of practice and some previous explorations, many talented and intelligent people have realized the mystery of the thousand forgings.

Now the group of people at the head are attacking the spirit forging.

When the Force arrives, the blacksmith's team will grow again and become more productive.

Passing through the forging area, Summer Spirit took the Titan down another level.

If the above is just the most basic work area, then this layer is the real core of the Martial Spirit Research Institute, where the elites gather.

Research Zone.

There are only two main areas of research today.

Soul Guide and Forge.

Or it can simply be said that both of them are in the service of the industrialization of the mainland.

Due to the lack of talents in related majors, everything can only be cultivated from scratch.

After returning from the Yin and Yang Upside Down Mountain, Xia Ling handed over the samples of the soul guide lamp he made and stacks of materials, drawings, and formation books to his subordinates who had been cultivating for several years.
